Gordon Allport described three basic traits which were of utmost importance in comparison to thousands of others. Describe cardinal, central and secondary traits

*Cardinal traits* - characteristics that influence most of a person's behaviours and ways they organize his life (dominant traits - e.g. selflessness, power-motivation). Cardinal traits influence central and secondary traits. *Central traits* - major characteristics of personality easy to infer, like honesty, shyness or charisma *Secondary traits* - personal characteristics more limited in occurrence - can be described as preferences - e.g. love for modern art, pescatarian or veganism, attitudes

The hypothalamus releases two direct hormones into the posterior pituitary. What are they and what do they do?

- ADH (Antidiuretic hormone, aka vasopressin) increases reabsorption of water in collecting ducts of the kidneys + is secreted in response to plasma osmolarity or increased solute concentations in the blood. - Oxytocin - stimulates contractions during labor + milk letdown during lactation.

Some of the key hormones released by the hypothalamus into the pituitary are GnRH, GHRH, TRH and CRF. What do each of these do as they go bind to receptors in the anterior pituitary?

- Gonadotropin-releasing hormone (GnRH) --> stimulates release of FSH and LH - Growth-hormone releasing hormone (GHRH) - stimulates release of growth hormone (GH) - Thyroid-releasing hormone (TRH) - release of thyroid-stimulating hormone (TSH) - Corticotropin-releasing factor (CRF) - release of adrenocorticotropic hormone (ACTH)

The release or inhibition of PTH is controlled by the amount of calcium in our blood. When Ca levels drop, PTH is released - talk about how PTH not only increases Ca levels, but also in terms of phosphorus homeostasis.

- Increases reabsorption/decreases excretion of calcium by kidneys - Increases absorption of calcium in the gut - Increases bone resorption of Ph and Ca - Reduces kidney reabsorption of Ph

In a stressful event, the body goes into "fight or flight mode, where the body increases heart rate and decreases digestion. Hans Selye developed a sequence of physiological responses called the general adaptation syndrome - describe it's three distinct stages (alarm, resistance, exhaustion)

1) Alarm - initial stage where body activates sympathetic NS - hypothalamus stimulates pituitary to release ACTH* which stimulates the adrenal glands to produce cortisol to maintain steady supply of blood + adrenal medulla to release epinephrine and norepineprhine* 2) Resistance - continuous release of hormones keeps the sympathetic NS stimulated for the body to remain engaged to combat stressor 3) Exhaustion - when the body can no longer maintain elevated response with sympathetic NS activity - individuals become more susceptible to illnesses and medical conditions, and death in extreme cases *ACTH = adrenocorticotropic hormone; epinephrine/nor is the same as adrenaline/noradrenaline

Studies have shown three factors influence our ability to multitask. What are they?

If there were no cochlear fluid, would audition be possible? How would the hair cells be affected?

Any vibrations from the stapes to the oval window would move air, whose movement would have a significantly smaller effect on hair cells; thus, they wouldn't reach threshold, making audition impossible.

As many as __% of those with major depressive disorder die by suicide.

As many as 15% of those with major depressive disorder die by suicide.

In terms of homeostasis and the body's ability to adapt, why do regular drug users need a higher dose of drugs over time?

As the body adapts to drug use, it begins to prepare itself before the drug user takes the drug. Taking external and environmental cues, the brain begins to prepare the body and preemptively lowers heart rate, etc. - thus, the same dose of drugs over time is not as effective and drug users require more of the drug to achieve the same high.

As one becomes addicted to cocaine, how does the brain develop a tolerance causing the individual to take more of the drug to get high?

As the brain gets influxes of dopamine consistently, it adapts in order to balance out the unnatural levels of "happiness" or "pleasure" received from the dopamine. Thus, it shuts down some post-synaptic receptors to regulate this. As a result, as one becomes addicted to cocaine, the brain adapts and shuts down some dopamine receptors, leading to the individual needing more cocaine to achieve the high.

At the optic chiasm, how are the nasal and temporal visual fields sorted? What purpose does this serve?

At the optic chiasm, rays from the nasal field cross at the chiasm while those from the temporal do not. This allows all the information from the right visual field to go to the left side of the brain, the from the left visual field to the right side of the brain. Both eyes see both visual fields to a degree, our brain converts it into one image.

Describe the types of decision making heuristics: - Availability heuristics - Representativeness heuristics

Availability heuristic are when we make decisions or try to decide how likely something is - use examples that are readily available and easily come to mind - sometimes correct but not always.

BMR - triiodothyronine (T3) and thyroxine (T4) Calcium homeostasis - calcitonin

Albert Bandura's Bobo doll experiment is famous for coming up with the social cognitive theory of personality. What were his crucial ideas?

Bandura's concepts of *reciprocal determinism* and *locus of control* were crucial to the social cognitive perspective. Reciprocal determinism - idea that out thoughts, feelings, behaviour and environment all interact with each other to determine our actions in a given situation. Locus of control - level of control people feel they have over the environment, or the environment has over them.

There is a structure in the accessory olfactory epithelium called the vomeronasal system, which has specific cells that respond to pheromones. What are these cells? (Hint: there are two types)

Basal cells and apical cells

In addition to the cochlea, the brain uses __________ to distinguish between high and low frequencies.

Basilar tuning. The basilar membrane inside the cochlea contains many hair cells

Schizophrenia can also include a positive symptom of disorganized behaviour is catatonia - what does this refer to?

Catatonia refers to certain motor movements and tendencies seen in patients with schizophrenia - may include reduction of spontaneous movements, or even rigid posture and refusal to be moved. Echolalia (repeating persons words) or echopraxia (repeating persons actions) may also be associated with catatonia.

When an Ion channel opens due to receptor binding, do cations or anions flow into the cell, causing depolarization?

Cations. When a molecule binds to a receptor on an ion channel, the ion channel opens and +ions begin to flow in, causing depolarization, and an action potential.

Our daily cycle of sleeping and waking up is regulated by internally generated rhythms called __________________

Circadian rhythms. Our circadian rhythms approximate 24-hour cycles and are somewhat affected by external cues such as light.

Noam Chomsky is known for his study on transformational grammar, and advocated for the existence of some innate capacity for infants to learn language. Which theory of language is this referring to?

Chomsky's theory refers to the nativist theory (biological/innatist) of language development - states that infants have an innate ability to learn language. This innate ability was called the language acquisition device (LAD) - theoretical pathway in the brain that allows infants to process + absorb language rules

Describe the two main types of strategies used in signal detection theory.

Conservative strategy - always say no unless 100% certain of a signal. Downside is you'll always get correct rejections, but may have some miss's. Liberal strategy - you'll always get the hits but then may also get some false alarms

Describe complex behaviours

Complex behaviours are a category somewhat between innate and learned behaviours - sort of like a spectrum. Think insects: an insect has an innate ability to fly, but through learning it becomes more efficient at flying (adaptive improvement).

Compare compliance, identification and internalization (all ways of being motivated by different influences or pressures)

Compliance is doing what you are asked regardless of whether you want to or not. Identification - when we go along with something under motivation of being like a certain famous figure Internalization - conforming not only publicly but also privately with a certain behaviour - internalizing the ideas - most powerful because not only do you, but you also want to!

How does a dermatome encode a location of stimulus?

Each dermatome corresponds to an area of skin supplied by mainly one spinal nerve. Whichever dermatome is firing indicates the position.

What are the three elements of secondary appraisal?

Evaluating harm, threat and challenge. The organism evaluates harm (damage caused by the event), the threat (potential for future damage caused by event) and the challenge (potential to overcome and maybe benefit from the event). Individuals who perceive the ability to cope experience less stress.

Excess insulin causes hypoglycemia - low blood glucose conc., and underproduction, insufficient secretion or insensitivity to insulin can cause diabetes. Hyperglycemia is characterized by excessive glucose in the body - in the kidneys, it will overwhelm nephrons and be excreted in urine - causes polyuria (excess urination) and polydipsia (excess thirst) Type I (insulin-dependent) diabetes is caused by autoimmune destruction of beta-cells, causing little to no insulin production Type II (non-insulin dependent) diabetes is due to receptor level resistance to insulin - partially inherited partially due to diet and environment.

Remaining in stress and overdrive for too long puts your body in a system of overdrive. What are some of the physical effects of stress on the immune system?

Excess stress can lead to a suppressed immune system via too much inflammation - arthritis is an example. However, if the body gets conditioned to chronic stress, then the immune system can get suppressed, making us more susceptible to illnesses and other things like reduced healing rate.

What are pheromones?

Excreted or secreted chemicals that triggers an innate social response in members of the same species. Linked to mating, fighting, and communication.

Experience - If your spouse speaking to you is a common experience, you may be more likely to recognize it. Motivation - If you are motivated to impress your spouse, you may be more likely to pay attention. Alertness - If you are less tired while studying, you will be more likely to perceive that your spouse is speaking to you.

What are explicit (declarative) memories?

Explicit memories are facts or events that can clearly and explicitly be described (e.g. state capitals, vocabulary etc.) - uses semantic memory (having to do with words) or episodic memory (memory for events)

Remaining in stress and overdrive for too long puts your body in a system of overdrive. What are some of the physical effects of stress on metabolism?

Extra or psychosocial cortisol release can lead to excess glucose in the blood stream - can have profound effects on our metabolism and cause diabetes.

Motivation can be described as the purpose/driving force behind action. Can be categorized based on what drives people to act. Differentiate between extrinsic and intrinsic motivation.

Extrinsic motivation - external forces driving motivation - e.g rewards and punishments Intrinsic motivation - internal motivation from within oneself - e.g. interest by a task, or pure enjoyment (me at the gym)

Becky is one of those people who is never upset. She is always calm and collected. After hanging out with friends, she tends to get worn out. Sometimes she believes that some of her friends are out to get her even though they are not. Hans Eysenck believed that Extraversion, Neuroticism, and Psychoticism were the three major traits of one's personality. How do these three traits apply to Becky?

Extroversion is the degree to which someone is outgoing. Becky would be seen to have little of this trait. Neuroticism is one's emotional stability, which is sounds like Becky has a lot of. Psychoticism is the degree to which reality is distorted in someone's view. In this case, Becky's view of reality is distorted so she would score high in psychoticism.

True or False? In the Milgram experiment, when the experimenter held a clipboard, obedience of the participant decreased because they knew the experimenter should have known better.

False. In the Milgram experiment, when the experimenter held a clipboard, obedience of the participant increased due to the increased authority of the person giving them the command.

True or False? In the Milgram experiment, when the experimenter was standing right behind the participant, obedience of the participant decreased because they knew the experimenter more intimately.

False. In the Milgram experiment, when the experimenter was standing right behind the participant, obedience of the participant increased because obedience increases as physical proximity and closeness increase.

Flat affect refers to the symptom where there are virtually no signs of emotional expression in the patient. Inappropriate affect - discordance with content of speech - e.g. laughing while describing someone's death

Sigmund Freud's Dream theory: manifest content and latent content

Freud said dreams represent our unconscious wishes, urges, feelings and conflicts. He separated dreams into their manifest content (what one actually sees) and their latent content (the underlying significance/hidden meaning behind these elements). Iceberg analogy - what you see vs. what is underlying.

Libido is the natural energy source that fuels the mechanisms of the mind. When Libido becomes fixed at a certain stage of development, what does Freud propose occurs at this point?

Freud would propose that you would end up stuck in that stage of development. So if your libido was stuck at an oral stage of development, you would have oral traits and personalities such as being very talkative, maybe smoking, etc.

Differentiate between Freud, Jung and Alder in terms of their psychoanalytical theories of personality.

Freud's major assumption was that behaviour is motivated by inborn instincts; Jung's principal is that a person's conduct is governed by inborn archetypes; Alder's theory assumes people are primarily motivated by striving for superiority.

Compare and Contrast the function of G-Protein Coupled receptors and Ion Channels in terms of the Gustatory System?

GPCR: A sweet, umami or bitter molecule binds a GPCR which causes a conformational change. The G-protein then dissociates which opens an ion channel and thus causes the cell to depolarize and fire an Action Potential. Ion Channel: A sour or salty molecule binds to a receptor on an Ion channel which opens causing the cell to depolarize and fire an Action Potential They end up doing the same thing but the initial trigger is different.

Theories of multiple intelligences also have support. What was Howard Gardner's theory of multiple intelligences? How about psychologist Robert Sternberg's Triarchic theory?

Gardner's multiple intelligences - 7 defined types of intelligence: linguistic, logical-mathematical, musical, visual-spatial, bodily-kinesthetic, interpersonal and intrapersonal - all independent of each other. Sternberg's 3 intelligences: Analytical (IQ test relevant), creative and practical intelligence (to solve ill-defined problems).

Describe the role of glucagon in the body

Glucagon is released during times of fasting by alpha cells of the islets of Langerhans - low glucose concentrations stimulate secretion of glucagon to trigger degradation of protein and fat, conversion of glycogen to glucose, and production of new glucose via gluconeogenesis. When glucose levels are high, glucagon release is inhibited.

Glucocorticoids Mineralocorticoids Cortical sex hormones

Motor skills can be broken down to two skills - differentiate between gross and fine motor skills

Gross motor skills are movements of large muscle groups and whole body motion (sitting, crawling, walking) - develop earlier Fine motor skills are movements of smaller muscles like fingers and toes + delicate movements and tracking motion

The upper membrane of the Organ of Corti contains Cilia (Hair Cells) known as the ___________.

Hair bundle

Why are some hallucinogens used to treat patients with PTSD (post traumatic stress disorder)?

Hallucinogens can allow people to access painful memories from the past without strong emotions, therefore allowing people to properly handle such an experience - not possible under normal circumstances.

What are the physiological effects of hallucinogens? What are some examples?

Hallucinogens cause individuals to experience distorted perceptions, including hallucinations or heightened sensations that are not real. They may cause increased/decreased energy but are classified by their perceptual effects. E.gs - LSD, psilocybin, PCP

How did Hans and Sybil Eysenck come up with their trait theory? (hint: PEN model)

Hans and Sybil Eysenck used factor analysis to group behaviours that typically occur together and assigned labels to those groups. They described three traits in the *PEN Model* - *Psychotism* (measure of social deviance and nonconformity); *Extraversion* (tolerance for social interaction + stimulation); and *Neuroticism* (measure of emotional arousal in stress) E.g. people who are more reserved and less outspoken tended to enjoy solitary activity and avoid stimulation.

What are the 6 components of the universal emotions?

Happiness, sadness, surprise, anger, disgust, fear

Levi has a long Dopamine-4-receptor gene. He also hates sky diving, gambling, and even stays home on Halloween to avoid the thrill. He is very calm and not interested in such activities. Do Levi's actions confirm or disconfirm the Biologic Theory?

Having a longer Dopamine-4-receptor gene is associated with being a thrill-seeker, but just because you have a genetic disposition for something doesn't mean you will certainly act that way. For this reason, Levi's actions neither confirm nor disconfirm the Biologic Theory.

Cluster B (dramatic/emotional) is defined by four types of personality disorder. Describe histrionic personality disorder

Histrionic personality disorder - characterized by being attention-seeking - usually are very extroverted, wear bright clothes, and can even sometimes be dramatic and seductive.

How does a human's Reconstructive Memory differ from a computer's memory?

Humans have reconstructive memory, which can slightly alter a memory as it is recalled based on one's mental state, mood, desires, etc. A computer's memory, however, will recall information accurately time and time again.

What was the problem with Broadbents theory?

If everything else were filtered out when selectively attending to one thing, how do you suddenly change focus when your name is called out in a group? (Cocktail party effect)

The opening or dark space in the middle of the eye, known as the pupil, adjusts its size based on the amount of light it receives. How does the pupil adjust its size in a dark environment? Light environment?

If it is dark outside, the pupil will expand to increase the amount of light able to enter the eye, while if it is light outside, the pupil will contract to decrease the amount of light able to enter the eye.

Can a phobia be considered an anxiety disorder?

If the phobia is causing distress or disability, then yes. It will be focused anxiety presenting with a specific pattern.

The Theory of Planned Behavior states that our behavior is determined by how we think about an action before we do it, specifically our implications and intentions. Our intentions are influenced by 3 things - attitudes, subjective norms, and perceived behavior control. Describe how your intention to study for the MCAT might be influenced by these three things.

If you have a negative attitude toward studying ("I hate studying"), others think your studying is a waste of time (subjective norms), and you feel like you can't control how much time you have for studying, you would be less likely to study.

Describe illness anxiety disorder

Illness anxiety disorder is characterized by being consumed with thoughts about having or developing a serious medical condition - individuals may be quick to become alarmed about health and excessively check selves for signs of illness

What are implicit (non-declarative) memories?

Implicit memories are more difficult to explain - they include memories for skills or how to do things (like bike riding). They lie outside of our conscious awareness. They use procedural memory (for procedures) and priming (previous experience influencing current interpretation of event)

When aging, which memories improve, remain stable and decline?

Improve: semantic memory, crystallized IQ, emotional reasoning Stable: Implicit memory, recognition Decline: recall, episodic memory, processing speed and divided attention

Why do we not realize how strange our dreams are when we are in REM sleep?

In REM sleep, the activity of the prefrontal cortex in the brain decreases. The prefrontal cortex is responsible for logical thinking, therefore our dreams in REM sleep can defy logic and not seem strange.

Compare the Information Processing Model of the nervous system to how a computer works.

In both the Information Processing Model and a computer, input is taken from the environment, processed, and outputs are produced.

Remaining in stress and overdrive for too long puts your body in a system of overdrive. What are some of the physical effects of stress on the heart?

In increased blood pressure, the blood vessels become respond by becoming more rigid and distend (swell from pressure inside) - increased vessel rigidity requires more force from the heart to move blood - leads to a cycle of elevating blood pressure, eventually hypertension. A damaging effect of this can be vascular disease (disease of blood vessels) - veins and arteries experience episodes of damage and inflammation + plaque build up. The coronary arteries is the worst place to experience this as they pump blood to the heart - coronary artery disease --> heart attack.

What are intentions in the theory of planned behaviour based off and formed by?

Intentions are based off (1) our attitudes towards a certain behaviour, (2) our subjective norms (what others/society thinks of our behaviour), and (3) perceived behaviour control (how hard it is to control our behaviour).

Contrast the order in which an event, emotion, physiological response, and appraisal/label is applied in the Schachter-Singer and Lazarus Theories of Emotion.

In the Schachter-Singer theory, first an event occurs, then a physiological response, then the labelling of the event/response, and then an emotion. In the Lazarus Theory of emotion, first an event occurs, then it is appraised, and that appraisal simultaneously determines the emotion and physiological response.

Describe the signalling pathway for the parasympathetic NS

In the parasympathetic NS, a long preganglionic neuron begins either in the brain or spinal cord, and carries the electrical signal via a long axon to the synapse with a short postganglionic neuron - synapse uses acetylcholine. The signal is then carried to the effector organ, where the synapse also uses acetylcholine. Note: both synapses use acetylcholine to carry the signal on.

Differentiate between inattentional blindness and change blindness.

Inattentional blindness: ere not consciously aware of things that happen in our visual field when our attention is directed elsewhere in that field. "miss something right in front of you" Change blindness: when we fail to notice changes in the environment - "you miss a change between a previous state and current state" - e.g. moms new haircut The difference is subtle but important

Serotonin is a neurotransmitter that is responsible for satiation and content. What happens to Serotonin levels when Dopamine levels increase due to heightened euphoria and pleasure?

Increase in dopamine levels causes subsequent decline in serotonin levels. Because serotonin is responsible for feelings like satiation, it explains why drugs can be so addictive and cause dependence.

Describe factitious disorder

Individuals who fake it because they 'want to be sick' - falsification of signs and symptoms

What is somatic symptom disorder?

Individuals with somatic symptom disorder have one or more somatic symptoms (which can be any symptom, may or may not be linked to a condition) that is accompanied by a disproportionately high level of concern about its seriousness, devotion of excess time and energy to it, or elevated levels of stress.

Sally is touching a hot stove. She thinks that the action potential that sent the signal to her brain must be really big and strong. How would you respond to Sally's reasoning?

Inform her that action potentials are actually always the same size. The intensity of her pain is encoded by frequencies with which nerve cells fire, which sends many action potentials to her brain over a short time period, rather than one large action potential signal.

Differentiate how the different processing routes of the elaboration likelihood model influences the types of characteristics of persuasion.

Information by this model is first filtered by our target characteristics, and then the content of the message/source characteristics are taken into account. Those in line with the central processing route - target characteristics (of listener) would likely be greater interest in topic, motivation to learn, and finding it important. In terms of message and source characteristics, the information is deeply processed. Those in line with the peripheral processing route - target characteristics might likely include lack of interest in or motivation to learn about the topic information, as well as little importance. In terms of message and source characteristics, the superficial factors like attractiveness have influence on persuasion.

Compare the effects of inhibiting versus destroying the Amygdala.

Inhibiting the amygdala will simply result in someone entering a mellow state. Destroying the amygdala will cause hyperorality, hypersexuality and disinhibited behavior, as seen in Kluver-Bucy Syndrome.

Describe innate behaviours

Innate behaviours are inherited, intrinsic behaviours that occur naturally. They are typically inflexible (not modified by experience), stereotypical species wide, and consummate (fully developed on first performance). Encoded by DNA, so subject to genetic change and mutations. Examples include blinking, eating, and many reflexes seen at birth.

Describe the role of insulin in the body

Insulin is released by beta cells of the islets of Langerhans - antagonistic to glucagon - secreted at high [blood glucose] - induces glucose uptake by muscles and liver cells. Insulin stimulates anabolic processes such as protein and fat synthesis.

What is interference?

Interference (or the interference effect) is another reason for memory loss - retrieval error caused by existence of other similar information.

Describe the term and what kind of cue it is: interposition

Interposition is a monocular cue - ability to know if something is in front of/behind another

Air moves through the nasal passage to the olfactory epithelium, which is sensitive to various molecules. What is an accessory olfactory epithelium?

It is a specialized epithelium which sends information to the accessory olfactory bulb

What is the sensory strip?

It is a specific part of your brain's cortex that contains the somatosensory homonculus, which is the map of your own body. It receives sensory input from the entire body (any pain, heat, fingers touching, feet etc). Information from any part of the body will go to one specific part of the sensory strip. There is a designated synapse area for your feet, your face, fingers, etc.

What is the just-noticeable difference (JND)?

JND is the threshold where you go from not noticing any tiny changes to just noticing a tiny little change in stimulus. Example with lifting weights, 2.2lbs vs. 2.05 (2.2 is just noticeable an increase from 2lbs whereas 2.05 would prob not be).

Jacob walked on the carpet with muddy shoes on. His Mom told him that before he could eat any dinner, he would need to clean the carpet. How might this situation relate to the Drive-Reduction Theory of Motivation?

Jacob's need for food is driving him to clean the carpet. Once he finishes cleaning the carpet and eats his dinner, his need is fulfilled and his drive is reduced.

Describe the Bobo Doll Experiment. What was the major conclusion of this experiment?

Kids observed a man beating up a Bobo Doll. After the children were tasked with putting together a frustrating puzzle, they were given the opportunity to play with a room full of toys. Several children copied the man's actions and proceeded to beat up the Bobo Doll. The conclusion was that children can learn through observation.

Virat Kohli consistently hits the ball with the middle of the bat compared to how he was 4 years ago. Is this an example of proprioception or kinesthesia?

Kinesthesia - hand-eye coordination improvements and awareness + behavioural

After 4 months out with an injury, a bodybuilder finds it easier to put on lost size than when he did initially. Why?

Kinesthesia plays a big part in muscle memory.

What is sleep deprivation?

Lack of sleep from one or multiple nights of poor quality or little sleep, resulting in irritability, mood disturbances, decreased performance and slow reaction time. Sleep deprivation is also linked to anxiety, depression, and some risk of obesity due to increased cortisol.

Describe learned behaviours

Learned behaviours are not inherited and develop in response to environmental stimuli, usually for some adaptive advantage. They are learned, extrinsic, permutable (pattern/sequence that is changeable over time), adaptable (can be modified), progressive.

What is a Lewy Body, and what role does it play in Parkinson's Disease?

Lewy Bodies are found in the substantia nigra in Parkinson's Disease, and mainly contain alpha-synuclein, a normal protein that will aggregate into these bodies and cannot be cleared. These bodies can be distributed amongst the cortex too, and may or may not be what kills the dopaminergic neurons.

How is light converted into electric signals and sent to the brain?

Light hits the cones and rods and causes a conformational change in membrane proteins, which leads to electric signals that go to the brain via the optic nerve

Parts of the eye: lens

Light hits the lens which is convex - the lens can change shape and get thinner or thicker

Sensation occurs when a physical stimuli is converted into a neural impulse. In terms of the human eye, what is the physical stimuli and what cells convert that into a neural impulse?

Light is the stimulus - it enters the eye and is converted to a neural impulse by photoreceptors (cones and rods)

The most common form of depression when referred to is Major Depressive Disorder. What is this disorder characterized by?

Major Depressive Disorder - usually characterized by a feeling of helplessness and worthlessness, low self esteem, persistent depressive mood, social isolation and discouragement/loss of interest in most enjoyable activities (anhedonia) Other physical symptoms such as appetite disturbances, weight fluctuations, sleep disturbances, decreased energy (lethargy) or excessive guilt can also be seen.

Bipolar disorders are a type of mood disorder characterized by episodes of both depression and mania. Describe manic episodes

Manic episodes are characterized by abnormal and persistently elevated moods lasting a week or longer - consist of at least three of the following: increased distractibility, decreased need for sleep, high self esteem, racing thoughts, increase goal-driven activity, increased talkativeness, and potentially involvement in high-rish behaviour.

William Masters and Virginia Johnson noticed certain factors increase sexual arousal - what did they find?

Masters and Johnson noted that physiologically, sexual arousal and motivation was linked to secretion of estrogens, progesterone and androgens, with a strong correlation between hormone conc and sexual desire. Another biological factor was smell - certain odors were shown to increase sexual desire and activity Cultural factors played a role in influencing pleasure and the interpretation of pleasure, as does cognition (sexual videos study). Culture and society also influenced what was deemed appropriate.

What might be the function for the Rooting reflex?

May be beneficial for breast feeding

What is meditation?

Meditation is an induced state of consciousness that is highly dependent on the practitioner and their beliefs. It usually involves the quieting of the mind to achieve a sense of relaxation. In Western traditions it is used for counseling and psychotherapy to provide relief from anxiety or worrying. Causes physiological changes like decreased heart rate and BP

What is memory decay?

Memory loss which is natural and not due to disorders - memories not often used or stimulated are often lost naturally over time as the neurochemical trace of a short term memory fades.

There are three characteristics that influence how we are persuaded for or against something that are part of the elaboration likelihood model - what are they?

Message characteristics - features of the message itself (was the argument logical? did it have key points? was there good grammar? too long/short? addressed the issue?) Source characteristics - (did the speaker seem knowledgeable or trustworthy? where was the messaged collected from? physical environment?) Target characteristics - characteristics of the listener/that you bring - (good/bad mood? high/low self-esteem? level of alertness? intelligence of listener? hungry or satiated?)

Describe mineralocorticoids and how they work (+ e.gs)

Mineralocorticoids are used in salt and water homeostasis - aldosterone is the common example, which increases sodium reabsorption in kidneys. Aldosterone is under the control of the *renin-angiotensin-aldosterone system* - decreased blood pressure = juxtaglomerular cells of kidneys secrete renin = cleaves inactive plasma protein angiotensinogen -> active form angiotensin I -> angiotensin II (by angiotensin-converting enzyme) -> stimulates adrenal cortex to release aldosterone. Negative feedback mechanisms for homeostasis. renin -> (cleaves) angiotensinogen -> angiotensin I -> (enzyme) angiotensin II -> aldosterone release stimulated

In the frame of the nature versus nurture debate, explain the significance of monozygotic and dizygotic twin studies and adoption studies.

Monozygotic twin studies have 100% of the same genes and almost 100% similar environments. Dizygotic twins have only 50% gene sharing but still almost 100% environment. In an adoption study, the monozygotic twins still share 100% of genes, but very different environments. A combination of these studies allows studying effects of only genetic differences or only environment changes.

The three types of TrpV1 fibers, A-B, A-D, and C vary in size due to different levels of myelination. How does their relative myelination affect their function?

Myelin is very important for conduction as it increases the number of ions in the axons to create an action potential. Ions in the axons cannot escape through myelinated areas, and so the more myelinated the fiber, the faster the conduction speed. Furthermore, the more myelinated, the wider the axon = less resistance = faster conduction

How are night terrors different from dreams?

Night terrors are periods of intense anxiety during SWS - it is most common in children, who when experiencing, may thrash and scream and show signs of sympathetic overdrive (fast heart rate, rapid breathing) - can be hard to wake children as this occurs in slow-wave sleep.

DSM-5 Classification.

Neurodevelopmental disorders - distress caused by lack of NS development Neurocognitive disorders - lost function of the NS causing distress Sleep-wake disorders - distress/disability from sleep abnormalities (sleep apnea, insomnia) Anxiety disorders - some specific to phobias, but can be general too - fear and anxiety related (e.g. panic attacks) Depressive disorders - distress from abnormally negative mood Bipolar and related disorders - distress cause by both depressive moods and mania Schizophrenia spectrum + other - distress from psychosis Trauma and stressor related - distress from mentally traumatic or stressful events (e.g. PTSD) Substance-related/addictive disorders - distress from abnormal substance use leading to mental function disorders Personality disorders - distress related to personality (long term mental and behavioural features) Obsessive-compulsive disorders - distress related to obsessive and compulsive behaviour (OCD) Somatic symptom and related disorder - distress from psychologically derived symptoms from illnesses Feeding and eating disorders - distress from food related disorders (anorexia, bulimia) Elimination disorder - distress from urinating or defecating at inappropriate times Dissociative disorders - abnormalities from memory or identity Sexual dysfunction - distress from abnormalities relating to sex performance Gender dysphoria - distress from identifying as a different gender than that identified by society Paraphilic disorders - distress or disability fro sexual arousal from what is considered unusual stimuli Other disorders - one who appears to have a mental disorder causing distress/disability but doesn't fit into another category

There are three ways for a neuron to encode timing (when a stimulus starts and stops? Describe each: - Non-adaptive - Slow-adapting - Fast-adapting

Non-adaptive: neurons fire at a constant rate over time Slow-adapting: neuron firing will slowly adapt to stimulus with time - action potentials start incoming fast but become less frequent until finally stopped Fast-adapting: neuron firing will be rapid initially and then stop, and fire again once the stimulus stops

There are several types of anxiety disorders. Describe Obsessive-Compulsive disorder

OCD is characterized by obsessions (persistent, intrusive thoughts and impulses) which increase tension or stress level, leading to compulsions (repetitive tasks). The relationship between the two is key - obsessions raise stress level, compulsions relieve the stress. It is a disorder when it comes to the point of disrupting or affecting someone's life and the behaviour becomes a problem.

Cluster C (anxious/fearful) is defined by three types of personality disorder. Describe obsessive-compulsive personality disorder

OCPD - individual affected is a perfectionist and inflexible, tending to like rules and order - also may show excessive stubborness, lack of sense of humour, inability to throw worn out clothes, etc. DIFFERENT from OCD - OCD is

Compare and contrast Obsessive Compulsive Disorder and Obsessive Compulsive Personality Disorder.

Obsessive Compulsive disorder is known for having compulsions on outside tasks or objects. Ego-dystonic. Obsessive compulsive personality disorder has a focus on their life being completely ordered and controlled, not on some outside object. Ego-syntonic.

Why is that when one has a cold and their nose is stuffy, their sense of taste is diminished?

Olfaction (smell) and gustation (taste) senses are connected. When someone eats, molecules travel to the back of the throat and nose, so when eating one's sense of taste is being used in conjunction with one's sense of smell. When someone has a cold, their sense of smell is knocked out, therefore diminishing their sense of taste.

By what mechanism does MDMA (ecstasy) function as both a stimulant and hallucinogen?

On the stimulant side, ecstasy increases dopamine and serotonin levels, leading to increased heart rate, CNS activity, blood pressure, dehydration. Overdoing it can lead to damaged serotonin receptors. On the hallucinogen side, excess ecstasy can cause perceptual changes including hallucinations and a feeling of connectedness.

When do on-center bipolar cells turn on? What about off-center bipolar cells?

On- and off-center refer to to the status of a bipolar cell being either ON or OFF. For an on-center bipolar cell, it is turned ON when light shines on the center of the rods (rods turn off). Off-center bipolar cells refer to bipolar cells being turned ON in the absence of light on the center of rods (rod cells turned on). See image for more details.

While referred to as the same class of psychoactive drugs, what is the small distinction between Opiates and Opioids?

Opiates are used to describe the drugs found naturally, while opioids are those made synthetically.

What differentiates the effects of opiates/opioids vs. depressants?

Opiates can also work as analgesics. Also, the two classes work via different mechanisms: Opiates - stimulate endorphin receptors. Depressants - enhance GABA receptors.

What defines stress?

Our response to challenging events (physio-, cognitive or behavioural) defines stress

Cluster A (Odd and eccentric) is defined by three types of personality disorder. Describe paranoid personality disorder

Paranoid personality disorder is characterized by immense distrust and suspicion of others

Ethology refers to the scientific and objective study of behaviour, usually in an adaptive sense. What are 'overt' behaviours?

Overt behaviours simply refer to observable behaviour. It can be broken down to innate, learned and complex behaviours.

One form of response to stress is to "tend and befriend" for things like pair bonding - what is the hormone released and responsible for this? Why is it seen more in females?

Oxytocin It is more common in women because it is more linked to estrogen.

Describe the third step of the phototransduction cascade. Transducin binds to PDE, what happens next?

PDE is triggered to convert cGMP, necessary for Na+ channels, to GMP. There is hence a decline in [cGMP] and a rise in [GMP]

PTH is water soluble and does not require a protein carrier to travel in the blood. What does this tell you about PTH? How would work?

PTH is a peptide hormone, since it is water soluble and doesn't require a protein carrier. In the cell, PTH would not be lipid-soluble and so would not be able to pass through a plasma membrane. Thus, it would bind to a receptor within the membrane and signal a second messenger.

Compare the Pegword and Method of Loci mnemonic devices.

Pegword devices are number and verbally based (match numbers with rhyming words, "one is a gun"), whereas Method of Loci is based on location (putting items in different rooms of your house or something like that).

Describe the Solomon Asch Conformity Study.

People are asked to identify which line (A, B, or C) is equal to the line of interest. Only one person is actually a participant, and they are found to go along with the group even when they knew the group was wrong. The participant went along with the group at least once 75 percent of the time. The participant went along with the group every time 37 percent of the time. When alone however, the participant made errors less than 1 percent of the time!

Hormones can be classified into three types - what are they?

Peptide hormones steroids amino-acid derivatives

Describe peptide hormones

Peptide hormones are made up of amino acids - derived from larger precursor polypeptides that undergo Golgi modification

Which of the following reflexes newborns are born with are permanent reflexes? Neonatal reflexes? - Breathing reflex - Rooting refelx - Eye blink reflex - Pupillary reflex - Swimming Reflex - Moro Reflex (flailing arms out when startled - Galant reflex (when stroked on side, baby will roll onto that side - Swallowing reflex - Palmar grasp reflex -Stepping reflex

Permanent reflexes: Breathing, eye blink, pupillary, swallowing Neonata reflexes: rooting, swimming, moro, galant, palmar grasp, stepping

Personality disorders are patterns of behaviour that are inflexible and maladaptive, causing distress or impaired functioning in cognition, emotions, interpersonal functioning or impulse control. What does it mean to say personality disorders are ego-syntonic?

Personality disorders are ego-syntonic, meaning that the individual perceives their behaviour as the correct, normal way and is harmonious with their goals. It is in contrast to ego-dystonic

Describe the three elements of emotion/emotional response: cognitive, physio-, behavioural

Physiological response - when feeling is experiences, arousal is stimulated by ANS - physiological component includes changes in heart rate, breathing rate, skin temp, blood pressure. Behavioural response - includes facial expressions and body language - e.g. smiling, hand gestures Cognitive response - this is the subjective interpretation of the feeling being experiences - largely based on memories of past experiences and perception.

The _______ funnels sound into the ___________, where it will travel to the _______________, where the sound waves are then converted into ossicle vibrations. To fill in the blanks, please choose 3 from the following options: - Semicircular Canals - Pinna - Tympanic Membrane (eardrum) - Auditory Canal - Stapes

Pinna, Auditory Canal, Tympanic membrane

Describe the following retrieval cues: Spreading activation (priming)

Priming is the effect where one stimulus or concept activates a node in our semantic memory to think of other linked concepts being unconsciously activated - also called spreading activation e.g. the concept of red could relate to similar colours like orange, and also objects like roses or fire engines

Describe the term and what kind of cue it is: relative size

Relative size - monocular cue that allows us to perceive two things far apart as relatively the same size When objects are of relatively equal size, the one closer takes up more space in the visual field

What are problems in the brain area related to schizophrenia relating to the prefrontal cortex and hippocampus?

Prefrontal cortex - dysfunction in the prefrontal cortex Hippocampus - schizophrenics often have smaller hippocampus's

What are examples of primary and secondary sex characteristics?

Primary - genetilia - testis, ovaries Secondary - voice changes, body hair, breast and hip development, pubic and underarm hair

Describe the cognitive appraisals of stress: primary, secondary appraisal and reappraisal

Primary appraisal - stage 1 - initial evaluation of the environment and associated threat - can be irrelevant, benign or positive, or stressful. Secondary appraisal - stage 2 - begins when threat revealed by primary appraisal - evaluating whether the organism can cope with the stress Some events require ongoing monitoring through constant reappraisal.

What is priming?

Priming is the effect where exposure to one stimulus influences response to another stimlus.

Jimmy agrees to eat 10 hot chili peppers with his friends. How would Private Conformity play out in this situation? What about Public Conformity?

Private Conformity would entail Jimmy agreeing inwardly and outwardly that eating 10 hot chili peppers is a good idea. Public Conformity would entail Jimmy eating the 10 hot chili peppers and agreeing that it is a good idea outwardly while feeling it is a bad idea inwardly. A private conformity will actually change your internal beliefs, whereas public would only make you put on a public persona.

What is bottom up processing?

Process begins with the stimulus, and the stimulus influences our perception. e.g. looking at a cockpit of a plane as a novice - you look at all the parts and gauges and data received drives your perception

What are the main differences between proprioception and kinesthesia?

Proprioception can be thought of as a cognitive awareness of your body in space and is more subconscious Kinesthesia can be thought of as behavioural, as your brain can consciously detect a movement and improve at that movement to better complete the task at hand.

One of the senses not often talked about in school is the sense of proprioception. Describe it.

Proprioception is defined as our ability to sense where our body is in space - our sense of position and balance.

Proprioception spindles are receptors in the muscles, often compared to springs. How do these receptors communicate position to your brain?

Proprioception spindles can sense when the muscle contracts and stretches, and stretches itself. When the protein within gets stretched, it fires a signal to the brain. The ability to know when each muscle in our body is contracted or relaxed gives us our sense of position in space, hence our proprioception.

Compare and contrast the Psychoanalytic Theory and the Humanistic Theory?

Psychoanalytic Theory thinks of us as being controlled by our unconscious. Sees us as animals that have intense desires. Humanistic Theory, however, views us as being in control and focuses on our conscious thoughts and actions. Sees us as inherently good and wanting to improve.

Compare and contrast puberty and adolescence.

Puberty is a 2-year long period for sexual maturation and drastic body changes that ends with the ability of sexual reproduction. Adolescence is a transition between childhood and adulthood seen as starting with puberty and ending once someone is an independent adult (self-supported).

Parts of the eye: pupil

Pupil is the opening of the eye which allows light in - it is controlled by the iris via sympathetic division of autonomic nervous system - dilates when it's dark out (sympathetic) so more light can enter light; constricts when its bright out (parasympathetic) so less light enters.

How is cholesterol (and after that steroid hormones) biosynthesized from isoprene groups and pyrophosphate (a good leaving group)?

Pyrophosphate is a weak base, making it a good leaving group. Electrons from one pi bond in isoprene will replace a pyrophosphate group of another isoprene to join - once there is a 30 carbon backbone (a squalene), ring closing reactions occur to close a 4-ringed chain, forming the cholesterol structure. Thereafter, cholesterol can be modified to form a steroid hormone.

Describe REM sleep and why it is also called paradoxical sleep

Rapid eye movement (REM) sleep is interspersed between cycles of Non-REM sleep stages. In this stage, arousal levels reach that of wakefulness but muscles are paralyzed. It is thus called paradoxical sleep because one's heart rate, breathing patterns and EEG mimic wakefulness, yet the individual is in deep sleep.

Describe the term and what kind of cue it is: relative height

Relative height - monocular cue - objects that are higher in the visual field are more distant

Describe the term and what kind of cue it is: retinal disparity

Retinal disparity/stereopsis - binocular cues - eyes separated by 2.5" (disparity); 2 eyes used to provide slightly different images on the retina

Describe rote rehearsal

Rote rehearsal (or maintenance rehearsal) is the repitition of a piece of info to either keep it within working memory (and not forget) or store it in short-term and eventually long-term memory. This rehearsal is generally not effective in facilitating later recall

Compare and contrast the mechanism and effects of the secondary messenger system and primary messenger system.

Secondary Messenger: After first hormone is bound on an extracellular receptor, a series of reactions will cause a secondary messenger like cAMP to be produced in bulk. This allows amplification! Primary messenger: The receptor is intracellular. Hormones cross the cell membrane and bind to receptor. That binding can directly effect transcription/translation. It is simpler, but does not allow for amplification.

Jacob says he has reached self-actualization after winning an Olympic Gold medal in the high jump. He used steroids to achieve this feat and was really only doing it for the fame and fortune. Would Maslow agree with Jacob?

Self actualization revolves around reaching one's maximum potential. If he was really doing it for the fame and fortune only, and not self-improvement, think about it. Self-actualizers are those who reach their full potential and these individuals are true to their own moral principles. Jacob is not focused on reaching his full potential or on obeying his own moral principles. He is most likely trying to meet needs of self-esteem, and is not actually self-actualizing.

Describe self-serving bias

Self-serving bias is the notion that we ourselves couldn't commit atrocious acts or crimes applying to certain situations, such as the Milgram experiment or the holocaust.

What is sensory adaptation?

Sensory adaptation is a down regulation of sensory receptors over time to a change in stimulus

Why is Sensory adaptation important in terms of cells becoming over excited?

Sensory adaptation is necessary as otherwise cells remaining excited for too long leads to them being over-excited, which can induce damage and cell-death.

Describe the term and what kind of cue it is: Shading, lighting and contours

Shading/contours - monocular cue - recognition of shading and lighting to attain depth information

Describe the term and what kind of cue it is: shape constancy

Shape constancy - monocular cue - ability to recognize similar/same shapes even when in different orientation

Why do we dream? No one knows this answer, but what are some of the theories?

Sigmund Freuds theory- dreams are our unconscious desires and needs that we want to fulfill Evolutionary theory- some evolutionists believe dreams evolved as a ways to develop either problem solving and/or threat stimulation Other theories- can include to develop neural pathways, maintain and consolidate memories

Mwape just barely arrives at a new school. She meets two new friends, Becky and Sarah. Mwape starts inviting them over to her house and leading them in several of her favorite games. Does Mwape demonstrate Social Potency or Traditionalism. What about Sarah and Becky? Explain why?

Social Potency is the degree to which a person assumes leadership and mastery roles in a social situation. Mwape is demonstrating this by quickly taking control in her new friend group. Sarah and Becky likely demonstrate Traditionalism as they are quick to follow Mwape's lead.

There are several types of anxiety disorders. Describe social anxiety disorder

Social anxiety disorder is anxiety due to social situations - fear of being exposed to social situation or performance that may lead to embarrassment.

Compare Somatic Symptom Disorder and Conversion Disorder.

Somatic Symptom disorder can have any type of symptom, specific or general, can have extreme levels of anxiety over these symptoms, and may or may not be medically explained. Conversion Disorder, on the other hand, is characterized by neurological symptoms, like speech, swallowing, seizures, or paralysis. They are incompatible/undetectable with any test/exam.

What are the roles of somatostatin?

Somatostatin is produced by delta cells of the islets of Langerhans (pancreas) - stimulated by high blood sugar and AA concentrations - inhibitor for both glucagon and insulin. Also produced by hypothalamus to decrease GH secretion.

Sound waves hit the outer ear - how do they reach the inner ear?

Sound waves hit the pinna and travel down the external auditory meatus (auditory canal) and hit the ear drum (tympanic membrane), causing it to vibrate. This causes the 3 bone structure (malleus, incus, stapes) to vibrate back and forth. The stapes is attached to a the oval window, a membrane-covered opening that leads into the inner ear.

How do the Parvo Pathway and Magno Pathway compare in terms of: -Spatial Resolution (Detail)? -Temporal Resolution (time)? -Color Vision?

Spatial Resolution - The Parvo pathway can provide much greater detail, necessary for detecting form. Temporal Resolution - The Magno Pathway has faster processing, necessary for tracking motion. Color Vision - Only found in the Parvo Pathway.

Deutsch and Deutsch's Late selection theory

Spawned from the cocktail party effect. This shifted the selective filter aspect to after the perceptual meaning.

There are four stages of sleep. What are they characterized by?

Stage 1 - when you are drowsy or doze off - theta waves are experienced by this point (irregular waveforms, low F high V) - also called stage N1 Stage 2 - as you fall more deeply asleep - the EEG shows theta waves along with sleep spindles and K complexes (see image) - stage N2 Stage 3 and 4 are known as slow wave sleep (SWS) - delta waves are seen, though stage 3 is aka stage N3; at this point it is harder to wake someone.

Of the 4 main stages of sleep, which stages are characterized as Non-Rapid Eye Movement (non-REM)?

Stages 1, 2 and 3 (N1, N2, N3)

Describe steroid hormones and how they function.

Steroid hormones are derived from cholesterol (nonpolar molecules) and easily cross the cell membrane - they function by binding to intracellular/nuclear receptors to undergo confor-changes and induce increased or decreased transcription of certain genes. Dimerization is a common form of conformational change

What are the physiological effects of Stimulants? What are some examples?

Stimulants stimulate or intensity neural activity and bodily functions, i.e. increase CNS activity, heart rate and blood pressure - also causes one to be more awake and alert. E.gs amphetamines (like meth), caffeine, nicotene, MDMA/ecstasy, cocaine

What are subliminal stimuli?

Stimuli below the absolute threshold (less than 50% detected/not detected by the individual). Homer Simpson example:

A common effect of Alzheimer's is sundowning - what does this refer to?

Sundowning is the phenomenon of increase in dysfunction in the late afternoon and evening

True or false: The biological and trait perspectives are closely linked. In twin studies with identical twins raised separately, one of the supporting findings for these theories was that traits such as social potency and traditionalism were common in both twins.

TRUE: The biological and trait perspectives are closely linked. In twin studies with identical twins raised separately, one of the supporting findings for these theories was that traits such as social potency and traditionalism were common in both twins. social potency = degree to which a person assumes leadership in mastery roles in social situations traditionalism = tendency to follow authority

True or false: the *object relations theory* is a psychoanalytical personality theory that refers to objects as representations of parents/caregivers based on subjective experiences during early infancy - these objects persist into adulthood and influence interactions and social bonds.

TRUE: the *object relations theory* is a psychoanalytical personality theory that refers to objects as representations of parents/caregivers based on subjective experiences during early infancy - these objects persist into adulthood and influence interactions and social bonds.

True or false: the PEN model by Eysenck was expanded to the *Big Five*, which describes majority of people using the dimensions of five traits: openness, conscientiousness, extraversion, agreeableness and neuroticism

TRUE: the PEN model by Eysenck was expanded to the *Big Five*, which describes majority of people using the dimensions of five traits: openness, conscientiousness, extraversion, agreeableness and neuroticism acronym - OCEAN

Give an example of how framing a decision can change the choice a person will make.

Take the flu vaccine as an example. If I ask someone if they want to be protected from the flu, they would be likely to get vaccinated; if I ask if they want to receive a shot, they are less likely to get vaccinated. Framing makes a big difference in how someone views their choices!

Where in the retina is the image at its sharpest?

The fovea, due to high concentration of cone cells.

Why is Temperament often associated with the Biologic Theory?

Temperament related to mood, activity level, etc. - it is an innate disposition (inherited) and the Biologic Theory is focused on the innate causes of our behavior.

If a person strongly believes in the spotlight and resource models, what would their opinion be on multi-tasking?

That the ability to multi-task is ineffective, and attending to one set of stimuli is more effective.

One of Jung's archetypes is the self - describe what he means by the self.

The *self* - intersection between the collective unconscious, personal unconscious and conscious mind. This archetype strives for unity.

Why is Cognitive Theory seen as a bridge between Behaviorism and Psychoanalysis?

The *social cognitive* perspective focuses not only on how the environment influences behaviour, but also how we interact with the environment.

John knows that his family has a history of depression, and he has the disease version of the 5-HTTLPR gene (associated with depression in some cases). Knowing this, John avoids long-term stressors when possible and never develops depression. How can this be explained?

The 5-HTTLPR gene is only associated with depression if the person is in stressful situations often.

A child is taking a hearing test. How might the concept of Absolute Threshold of Sensation apply to this situation?

The Absolute Threshold of Sensation is a generally detectable stimulus. It is defined as the minimum intensity of a stimulus needed to detect that stimulus at least 50% of the time. Thus, for a child taking a hearing test, it would be the point at which the child begins to detect the sound in their ear at least 50 percent of the time.

Contrast The Behavioral Theory and the Psychoanalytic Theory.

The Behavioral Theory says that we are influenced by our environment and is focused on observable behavior. Psychoanalytic Theory, on the other hand, is focused on internal desires and mental states.

What makes the Biologic Theory unique as compared to the Humanistic and Psychoanalytic Theories?

The Biologic Theory posits that our behavior and personality are inherited whereas the Humanistic and Psychoanalytical Theory propose that they develop from our experiences. Certain traits and genes are coupled with certain behaviours, however not necessarily defining.

Contrast the Cannon-Bard theory of emotion with the James-Lange theory of emotion.

The Cannon-Bard theory claims an event can cause a physiological response and an emotion simultaneously. The James-Lange theory claims a physiological response will occur, and then its perception will cause an emotion.

Describe the Cannon-Bard theory of emotion. (hint: think separate and simultaneous)

The Cannon-Bard theory states that the cognitive and physiological components of emotion occur simultaneously and result in the behavioural component (action). This theory separates the two - disagrees with James-Lange - believes that one could experience physio- response without emotion. An event occurs and causes a response AND an emotion simultaneously E.g. heart races when you are scared but also when you run; "I am afraid because I see a snake and my heart is racing....run!"

Describe the James-Lange theory of emotion. (hint: think functionalist, William James = founder of functionalism)

The James-Lange theory of emotion states that a stimulus first results from physiological arousal, which leads to a secondary response in which the emotion is labelled. Peripheral organs receive signals and respond, and that response is labelled as an emotion by the brain. E.g. "I must be angry because my heart rate is elevated, skin is hot, blood pressure is high"

Draw or visualize an example of The Law of Closure. Describe this law.

The Law of Closure - objects grouped together are seen as a whole. We tend to ignore gaps and complete contour lines

Compare the nervous system and endocrine system, focusing on speed and duration.

The Nervous System can send signals and cause change very quickly, but the duration of these effects tend to be short. The Endocrine System will take much longer to send signals across the body, but the duration of these signals tend to last much longer.

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the Prototype-Willingness model (PWM)

The PWM says that behaviour is a function of six factors - past behaviour, attitudes towards behaviour, subjective norms, intentions, willingness to engage in a behaviour, and prototypes (models) This theory combines the planned behaviour and attitude-behaviour theories and adds onto it.

What is parallel processing?

The ability to detect all information relating to feature detection (color, form, motion) simultaneously.

What is depth perception?

The ability to perceive the world in 3 dimensions + distance of an object. Depth perception rises from a variety of depth cues (monocular and binocular cues).

Describe emotional intelligence

The ability to perceive, understand, manage and use emotions in your interactions with others

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the attitude-behaviour process model

The attitude-behaviour process model says that an event triggers an attitude, which influences our perception of an object or stimulus. Additional outside knowledge towards the situation or object, combined with our attitude, leads to our behaviour.

What is the major function of the basal ganglia (which contains the substantia nigra)?

The basal ganglia coordinates motor movements. It receives dopamine from the substantia nigra to function properly - it controls initiation and termination of movements, as well as sustaining repetitive motor skills and smoothening muscles.

Describe the behavioural theory of personality.

The behavioural theory states that personality is the result of the interaction between an individual and their environment.

Differentiate between the biomedical and biopsychosocial approaches to psych- disorders.

The biomedical approach assumes disorders have roots in biomedical/biological disturbances and abnormalities, and therapy focuses on interventions that rally around symptom reduction. The biopsychosocial approach assumes there are biological, psychological and social components that contribute to an individual's disorder. The biomedical approach is typically narrower than the biopsychosocial and fails to take into account psychological and social factors like lifestyle and socioeconomic status.

In terms of the difference of choroids, explain why cats have better night vision than humans?

The choroid in humans is black in colour, and so absorbs all light and reflects none. However, in cats the choroid is a shiny colour, and thus light not absorbed by the retina is reflected back onto the retina after striking the choroid and given another chance at retinal absorption, resulting in better night vision for cats.

What are the function of the ciliary body?

The ciliary body has the ciliary muscles which control shape of the lens (by pulling on suspensory ligaments), and ciliary epithelium that produces aqueous humor to bathe the eye front before draining into the canal of Schlemm

For patients with CRSD (Circadian Rhythm Sleep Disorders), daily rhythms like body temperature, alertness and hormone secretion are impaired. What is the circadian rhythm responsible for in a healthy individual?

The circadian rhythm is often called a "biological clock", because it causes sleepiness to gradually increase during the day, regulating sleep and wakefulness.

Describe the cognitive approach of motivation

The cognitive approach of motivation focuses on our rationale and decision-making ability

What does the cognitive process dream theory state?

The cognitive process dream theory states dreams are merely the sleeping counterpart of stream-of-consciousness

Describe the fourth step of the phototransduction cascade. We now have high [GMP] - so what?

The decline in [cGMP] is crucial because sodium channels throughout the rod cells require cGMP to be bound in order to remain open. Now, with them closed, less sodium enters the cell, causing the cell to hyperpolarize and subsequently turn off.

When talking about biases, what is the disconfirmation principle?

The disconfirmation principle states when a potential solution fails during testing it should be discarded - solution does not work. Confirmation bias may prevent one from doing this.

Within the prefrontal cortex, describe the function of the following: - dorsal prefrontal cortex - ventral prefrontal cortex - ventromedial prefrontal cortex

The dorsal prefrontal cortex is associated wit attention and cognition The ventral prefrontal cortex connects with regions of the brain responsible for experiencing emotion The ventromedial prefrontal cortex plays roles in decision making and controlling emotional responses from the amygdala

Describe Frued's element of the ego

The ego and superego both have conscious and unconscious elements. The ego operates according to the *reality principle*, and takes reality into account to inhibit or guides the activity of the id - guidance referred to as *secondary process*. The aim of this principle is to postpone the pleasure principle until satisfaction is actually obtainable. The ego also moderates the superego

How are the ego and superego related?

The ego mediates the desires of the superego, just as it does those of the id. The three are in conflict, and the ego's recourse for relieving anxiety caused by clash of the id and superego is via *defense mechanisms*

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the elaboration-likelihood model for persuasion

The elaboration-likelihood model theory separates individuals based on their processing of persuasive info - is more cognitive and focuses on the 'why' and 'how' aspects. There are two ways this model is processed: 1) At one extreme, those who elaborate extensively and think deeply - *central processing route* - the degree of attitude change depends on the quality of arguments by the persuader 2) Other extreme - those who do not elaborate much - *peripheral processing route* - looks at superficial and nonverbal persuasion cues (attractiveness, status, expertise)

What is the endocrine system?

The endocrine system is a system of organs called glands which release chemicals called hormones into the bloodstream to initiate an effect.

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the functional attitudes theory

The functionalist attitude theory states that attitudes serve four functions: knowledge, ego expression, adaptation and ego defence. *Knowledge* provides consistency and stability in thought. Attitudes can be *ego expressive* (to communicate and solifidy our identity; e.g. big Eminem fan, big Pats fan) and *ego defensive* (protect self-esteem or justify actions we know are wrong). They can also be *adaptive* - idea that one will be accepted if attitudes are socially acceptable.

How does a cochlear implant work?

The implant is a Receiver and has a tube called a Stimulator that goes all the way and connects to the cochlea. The receiver gets information from its adjacent structure called a Transmitter, which gets electrical information from the Speech Processor. The Speech Processor gets information from it's microphone, which goes to the Transmitter -> Receiver, which sends the information through the Stimulator into the cochlea, which converts that electrical impulse into a neural impulse. This restores some degree of hearing to individuals with nerve deafness

When talking about biases, what is belief perseverance?

The inability to reject a particular belief despite clear evidence to the contrary

Describe the incentive theory of motivation

The incentive theory explains behaviour as motivated by desire to pursue rewards + avoid punishments, rather than by arousal. It is based on the idea that if a behavior is rewarded, it will result in the behavior occurring again.

How is the lack of a reflex in an infant clinically significant in a pediatrician checkup?

The lack of a reflex can signal that a certain area or group of muscles is not developing properly.

Why do some astronauts or even scuba divers feel 'disoriented' at times?

The lack of gravity in space, or the effect of buoyancy in deep waters, will cause the carbonate crystals in the otolithic system to not function properly, as gravity is an essential component in its shifting and subsequent pulling on hair cells to indicate orientation and position.

What is the macula? Fovea? Difference?

The macula is the name given to a avascular region in the posterior region of the eye. The fovea is a dimple-like area in the center of the macula, densely populated with cones, which allows detailed vision and in colour.

A woman dreams about her boss getting eaten by a giant snake. What might be the manifest content in this example? latent content?

The manifest content is what she saw - her boss getting eaten by a giant snake. The latent content could be her suppressed feelings of anger toward her boss. Perhaps subconsciously she wants her boss to be out of her life.

In terms of storing memory, how is the Modified Semantic Networks (current theory) different than a simple hierarchical semantic network model?

The modified theory allows for a "hierarchy" based on personal experience and common knowledge, not necessarily just based on traits. This allows for individual differences in what connections exist in individuals, and differences in relative processing time.

A smoker who has been smoking for 6 years is aware of how damaging it is to his body, yet he cannot seem to stop smoking. In fact, he claims he smokes more cigarettes today compared to two years ago, when he tried to start quitting due to harm realization. How does the opponent-processing theory explain these phenomenon?

The opponent-processing theory explains that when a drug is repeatedly taken, the body attempts to counteract effects by changing physiology. It counteracts alcohol abuse, for example, by increasing arousal. The problem arises because this reaction lasts longer than the drug - results in withdrawal symptoms which are exact opposing effects of the alcohol or drug. This can create a physical dependence. The same phenomenon runs for nicotine, in cigs - it explains why the smoker smokes more today as he has an increased tolerance.

What is the optimal arousal theory of motivation?

The optimal arousal theory states people perform actions in order to maintain an optimal level of arousal - seek to increase arousal when it falls below their optimal level. The image shows the Yerkes-Dodson law which postulates a U shaped function between arousal and performance - performance is worst at extremely high and low levels of arousal, and best when at optimal levels.

Arriving at the scene, an EMT needs to quickly assess the situation, including any bleeding, discoloration, injuries, etc. How does the parallel processing of multiple vision pathways enable them to do this quickly and efficiently?

The parallel processing of multiple pathways allows different aspects (color, form, motion) to be processed quickly at the same time, and integrated at higher vision centers.

The autonomic nervous system is split into sympathetic and parasympathetic components. What do each do?

The parasympathetic nervous system controls homeostasis and the body at rest, and is responsible for the "rest and digest" function of the body. The sympathetic nervous system controls the body's response to threat, and "fight or flight" mode.

Talk about the parathyroid gland, which consists of 4 pea-sized structures on the posterior surface of the thyroid, and its hormone.

The parathyroid gland produces PTH (parathyroid hormone) - serves as antagonist hormone to calcitonin. The overall effect of PTH is a significant increase in blood calcium levels with little effect on phosphorus (phosphorus homeostasis).

A common issue with flash photography is the "red eye effect". What part of the eye anatomy causes the red eye effect, and how?

The red eye effect phenomenon is due to light reflecting back off the retina, which is a reddish colour.

How does Deutsch and Deutsch's Late Selection Theory differ from Broadbent's Early Selection Theory?

The selective filter that discriminates information to be processed in Deutsch's is after the perceptual processing, but is before this in Broadbent's.

If a salt receptor was accidentally expressed and activated in a sweet cell, would the sensed taste in the brain be salty or sweet? Why?

The sensed taste would be sweet. If the salty receptor in a sweet cell was accidentally expressed, it would trigger a cascade effect which would still fire an action potential up an axon leading to the designated area in the brain. By the Labelled Lines model, the axons do not mix, and thus the synapse in the brain would still be in the area that detects sweet tastes - thus, the taste would be sweet. Type of cell determines the taste sensed, not the receptor

Describe the signalling pathway for the sympathetic NS

The signal pathway consists of two neurons - starts with a short preganglionic neuron, whose cell body originates at the spinal cord and the axon extends into the PNS. The preganglionic neuron synapses with a long postganglionic neuron using acetylcholine, which extends to synapse to the effector organ (using epinephrine/norepinephrine) Note: the synapse between pre- and postganglionic neurons uses acetylcholine while the second between the post- and effector organ uses epinephrine or norepinephrine.

Clearly differentiate the terms stressor, stress reaction, and stress.

The stressor is the event that is causing the animal to have that stress reaction. The stress reaction is how the animal with the stressor physiologically responds. Stress is the combination of the stressor and stress reaction.

When talking about biases, what is confirmation bias?

The tendency to focus on info that fits an individuals beliefs while rejecting information that goes against them

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the theory of planned behaviour

The theory of planned behaviour states we consider our implications of our actions before we decide how to behave. The best predictor of our behaviour are our intentions in a given situation.

Parts of the eye: sclera

The thick white covering layer of the eye, does not cover the cornea - supplied nutrients by two bloodvessels: choroidal and retinal vessels. Composed of protein called collagen as well as elastic fibers

Jack sees a poor man on the street. He thinks to himself, "That poor fellow. He doesn't deserve this." Is this an example of the Just World Phenomenon?

This is not an example of the Just World Phenomenon. If it was, Jack would have said, "That fellow is getting what he deserves. He must be too lazy to get a job." Think of the "Just World Phenomenon" as a "Fair World", and it can be used to justify critical judgments.

When traveling to the Eiffel Tower for the first time, tourists may still get a feeling of deja-vu. Why is this the case in terms of bottom-up and top-down processing?

Tourists have probably seen pictures of the Eiffel Tower, so top-down processing will quickly recognize the structure before bottom-up processing can actually process the stimuli.

Parts of the eye: vitreous humor

Transparent gel in the eye behind the lens which supports the retina

Define the methods of problem solving: - Trial & Error - Algorithms - Heuristics

Trial and error - less sophisticated - various solutions to a problem are tried until one works Algorithms - formula or procedure for solving a certain type of problem - e.g. mathemetical or instructions set Heuristics are simplified principles to make decisions - rules of thumb - e.g. ismeans-end analysis (starts with the biggest problem -> smaller); working backwards (working way back from start point of a maze to find the beginning).

True. In the Asch experiment, when the participant was told to write their answers down, conformity of the participant decreased because they no longer had to state a dissonant answer out loud. When you know you are not being observed, your conformity will decrease.

True or false: in most cases, individuals with dissociative identity disorders have suffered of childhood abuse, either physical or sexual.

True. Most cases - individuals with DID have suffered of severe physical or sexual abuse.

True or false: Rods and cones have structural similarities

True. When experiencing pleasure, the Ventral Tegmental Area sends dopamine to the Amygdala, Nucleus Accumbens, Prefrontal Cortex, and the Hippocampus.

Type theories like the MBTI create a taxonomy of personality types - one well known theory describes type theories as Type A or Type B - what were these types?

Type A- competitive and compulsive behaviour; type B- laid-back and relaxed. Type A were found to be more prone to heart disease, though no evidence of higher mortality rates exist.

Why are Tyrosine derivatives treated as a separate class of hormones from the polypeptide class?

Tyrosine derivatives are made of exactly one amino acid that is manipulated, not multiple. The cyclic structure also gives tyrosine derivatives some non-polar characteristics, so they can act similarly to both Polypeptide and Steroid hormones in certain contexts.

Frued's psychoanalytical theory has heavy basis on unconscious desires and libido - describe these two.

Unconscious desires influence our behaviours, along with childhood experiences. Our personalities have memories, beliefs, urges and drives we aren't aware of, that make up this unconscious. Libido refers to natural energy source that fuels the mechanisms of the mind - it is fixated at certain psychosexual stages of development.

What is amplification?

Up regulation of a certain stimulus

How does priming affect selective attention?

We attend to information we have been primed for, even if not consciously thought about. For example, after eating, you would be primed to recognize food words in a word scramble. This would also explain the Cocktail Party Effect, as we'd have been primed to respond to our names.

Why do humans rely very little on pheromones? Which structure in the human olfactory system is not present that is present in other animals that rely on pheromones?

We lack the accessory olfactory bulb. We do have vomeronasal system but not the accessory olfactory bulb.

As sound travels through an ear, how many levels of amplification do we see? Why is this amplification of sound even necessary?

We see three levels of amplification - the first by the pinna capturing sound, the second by the ear drum, and the third by the 3 bones in the middle ear. The reason we need amplification is because in the inner ear sound is transmitted through a fluid, perilymph - sound travels through more resistance in fluid than in air.

The tip link of a kinocilium is attached to the gates of a K+ channel. Explain how an action potential is generated when fluid begins to move inside the cochlea.

When fluid moves in the cochlea, the tip links are pushed back and forth and subsequently stretched by movement in the cochlea. This stretching activates K+ channels they are linked to, allowing K+ to enter the cell. The entry of K+ activates Ca2+ channels inside the cell, and Ca2+ is also allowed into the cell. This causes an action potential which activates the auditory nerve.

When is the phototransduction cascade triggered?

When light is present and hits rod cells and turns them off

How is a pressurized sound wave formed when someone claps their hands?

When one claps their hands, a number of air molecules that were in a more open space are suddenly compressed into confined space between the palms. With less space to move, this compression forces them to be pressurized - to relieve this pressure, air molecules try to escape, which results in areas of high and low pressure = creating pressurized sound waves

Why do some users who take drugs in new locations overdose?

When taking drugs in a new location, the brain does not take external or ritualistic cues and hence has no time to adjust preemptively - thus, the same higher dose that would be needed in a drug users normal location would be too much when the body has not adjusted beforehand, leading to OD.

What is the crash?

When the body adjusts its homeostatic conditions with cues and the brain expects incoming drugs, but does not receive them, the time spent staying in preemptive preparation is the crash.

You look at a group of lightbulbs and notice that some are brighter than others. You are unable to tell however that two of the lightbulbs have any difference in intensity, seeming to be the same brightness. How does the concept of Just-noticeable Difference (JND) apply in this context?

When you can see a difference in the brightness of some bulbs, the level of brightness for said bulbs in comparison to the baseline has exceeded your just-noticeable difference (JND). When you do not perceive others as brighter, however, the difference in intensity has not passed your JND.

What is *wish fulfillment* and how is it part of the Id?

Wish fulfillment refers to mental imagery like fantasy or daydreaming - it serves as a ways to fulfill satisfaction, which is the function of the Id.

With Obsessive Compulsive Disorder (OCD), where does the distress or disability come into play?

With OCD, distress comes into their everyday life when their compulsions interfere with daily activities.

For months, Alterrique appeared to be depressed. However, this episode ends and Alterrique has extreme self-esteem and optimism, but also shows risky behaviors. Could Alterrique have been misdiagnosed and suffer from Bipolar Disorder?

Yes, Alterrique's behaviors after the depressive episode are characteristic of mania. Displaying both manic and depressive episodes is characteristic of bipolar disorder.

According to the DSM-5, is Sexual Dysfunction considered a mental disorder?

Yes, Sexual Dysfunction is considered a mental disorder because it involves Distress and Disabilities from abnormalities or performance of sexual acts.

1) sound waves are *caught by your pinna/auricle* (big part of external ear) and passed along into deeper ear 2) sound *passes through the external auditory meatus* (auditory canal), connecting into the middle ear --> *auditory waves collide with the tympanic membrane* (aka eardrum), which is the boundary between the two 3) *Ear drum vibrates and passes vibrations to bones in the middle ear (aka tympanic cavity)*, which *amplifies sound waves* when they enter the inner ear *through the auditory ossicles* (3-bone structure of the malleus, incus and stapes - aka hammer anvil and stirrup) 4) The 3 bone structure acts as a chain to *conduct sound through* another membrane, *the superior oval window, which sets fluid in the inner ear into motion, through which sound travels* 5) *inner ear converts sound into electrical impulses* to send to the brain - more on that later.

What is a flashbulb memory, and are they susceptible to reconstruction?

A flashbulb memory is an extremely emotional, vivid memory (positive or negative). They are still susceptible to reconstruction. A person after experiencing something like say, a traumatic experience, will be likely to remember the memory and things done on that day very vividly - this is the concept of flashbulb memories.

In the image behind this flashcard, try to match each letter with the number provided: 1. Iris 2. Lens 3. Aqueous Humor 4. Vitreous Humor 5. Ciliary muscles 6. Optic nerve 7. Retina 8. Pupil 9. Fovea 10. Cornea

What are the 3 types of nerve fibers? Distinguish between them

A-beta nerve fibers - largest diameters and plenty of myelin A-gamma nerve fibers - medium, some myelin C-fibers - smallest diameters, no myelin Combo of size and myelin changes how quickly each fiber can send an action potential

Sally has a bad attitude towards spiders. Describe this by each of the three components of attitude

Affective - Sally is scared of spiders (fear being the emotion) Behaviour - because of her fear, Sally will avoid spiders and going near them (action) Cognitive - Sally believes spiders are dangerous. All three contribute to form Sally's negative attitude towards spiders.

How do the functions of the external and middle ears differ from the inner ear?

All three portions of the ear are involved in hearing, but the inner ear is also involved in maintaining your equilibrium (proprioception).

Pancreas - from endocrine standpoint, small clusters of hormone producing cells are grouped into the islets of Langerhans - Islets contain three cell types each secreting a different hormone - what are they and what do they secrete?

Alpha cells - glucagon Beta cells - insulin Delta cells - somatostatin

Compare Alzheimer's Disease with Korsakoff Syndrome: - Cause of each? - Symptoms? - Treatment? - Permanent or Treatable?

Alzheimers: Unknown cause, problems based more on attention, semantic and abstract thoughts. Progressive and terminal. Untreatable. Korsakoff's Syndrome: Caused by lack of B1/thiamine, so lack of glucose metabolism, will have poor balance and abnormal eye movement along with memory/confusion issues. Can be treated and improve.

What is kinesthesia?

An awareness of the position and the movement of parts of the body by means of sensory organs. Kinesthesia is much more concerned with movement and behaviour, and is a key component of hand eye coordination and muscle memory.

Compare the differences in symptoms between patients with Broca's aphasia, Wernicke's aphasia, and conductive aphasia.

Aphasia is an impairment of language, due to injury. Broca's aphasia - damage to the Broca would result in impaired or slurred speech. Wernicke's aphasia - difficulty or inability to understand words + producing nonsense words Conductive (or global) aphasia - damage to the arcuate fasciculus resulting in loss of connection between the Broca's and Wernicke's areas - they are both in tact and hence so is speech production and language comprehension but the patient is unable to repeat something said to him. But with enough time patients will correctly get their point across via synaptic plasticity.

When graphing Signal detection theory, D represents the distance between the peaks of the noise curve and the signal curve. As D decreases, what happens to the frequency of misses/false alarms?

As D decreases, the range of signals and thresholds also decreases, and false alarms and misses would become more common.

How is attention split between multiple tasks, and why does this make multi-tasking less effective?

Attention is not actually split between two tasks simultaneously, but rather only focuses on one at a time. These gaps in attending to each task makes multitasking ineffective.

How would you describe attitudes (ABC model) and how they influence us?

Attitudes can be described as learned tendencies with three components: affective, behavioural, and cognitive components (ABC model). Affective component refers to how we feel emotions, which shapes our attitude Behavioural component refers to how we behave towards a subject, influencing our attitude Cognitive component refers to thoughts and beliefs or knowledge we form about something which influences our components.

Differentiate automatic processing from controlled (effortful) processing

Automatic processing is when information is gained without effort; controlled processing is active memorization of information. With practice, controlled processing can become automatic (think when you get good at a foreign language)

A week after his house was broken into in the night, James has a panic attack while trying to fall asleep in his bed his first night back home. Could he be diagnosed with a panic disorder?

Based on this information, no. James had an isolated panic attack that was somewhat justified by the situation, not a history of panic attacks for less warranted reasons.

Read this paragraph about the Prototype WIllingness Model: http://wiki.scetool.nl/index.php?title=Prototype_Willingness_Model What does it mean to say that the Prototype WIllingness Model is a Dual-processing Model? Can you relate this to a child who decides to smoke for the first time?

Basically, this theory says that there are two paths of influence on this child's behavior. The first path is rational and analytical (i.e. "It is okay to smoke because I've never been taught the consequences") . The second path is the social reaction path, which involves prototypes ("I know people who smoke and they are cool") and willingness to engage in the risky behavior ("I'm a daredevil, risk-taker kind of person").

Explain the difference between Belief Perseverance and Confirmation Bias.

Belief Perseverance is maintaining old, incorrect beliefs by ignoring or rationalizing against the dis-confirming facts presented to you. Confirmation Bias is when you intentionally seek out only facts to support your current opinion/decision.

Benzodiazepines, often shortened to "Benzos", can be prescribed for conditions from insomnia to anxiety. If their mechanism is opening chloride channels, how does "Benzos" repress insomnia and anxiety?

Benzos open up GABA (inhibitory NT) activated chloride channels on neurons - allowing more Cl- ions to flow in. The negatively charged anions makes the cell more resistant to excitation - thus they are used to repress anxiety or induce sleep/counter insomnia.

Electroencephalography (EEG) is used to record average electrical patterns of the brain - there are four characteristic patterns, or waves, associated with different states of waking or sleeping. What are beta and alpha waves?

Beta and alpha waves characterize brain wave activity when we are awake; Beta waves have a high frequency (12-30Hz) and occur when we are alert and attending a mental task - neurons are randomly firing Alpha waves occur when we are awake but relaxed with our eyes closed, and are slower than beta waves (8-13Hz) - more synchronized

How are circadian rhythms regulated?

Biochemical signals underlie the concept of circadian rhythms. Less light induces melatonin release for sleepiness, while more induces cortisol release for wakefulness. Sleepiness is attributed to increased levels of melatonin, a seratonin-derived hormone) released by the pineal gland. The retina is directly connected to the hypothalamus, which controls the pineal gland - decreasing light can trigger release of melatonin. In contrast, more light = cortisol release, which contributes to wakefulness. Increased light causes release of corticotropin releasing factor (CRF) from the hypothalamus - causes release of adrenocorticotropic hormone (ATCH) from anterior pituitary, which stimulates cortisol release.

The part of the retina that is directly in front of where the optic nerve exits the eye is known as the _____________.

Blind Spot. The Blind Spot is directly in front of where the optic nerve exits the eye - contains no rods or cones.

Differentiate between Anorexia and Bulimia nervosa

Both Anorexia and Bulimia are Feeding and Eating Disorders that lead to underweight patients. In Anorexia, the person consumes too little food consistently, whereas in bulimia, a person will binge eat and then purge it out (throw up the food).

Compare Schizotypal and Schizoid Personality Disorders.

Both Schizotypal and Schizoid Personality Disorders are part of the "Odd and Eccentric" Cluster. Schizoid Personality Disorder is characterized by emotional detachment, whereas Schizotypal personality disorder will both avoid close relationships AND hold magical/odd beliefs.

P.K.U (which codes for a liver protein) disorders can lead to a baby getting a buildup of phenylalanine and suffer neural defects. Giving the baby a phenylalanine-free diet will make the baby asymptomatic. Is P.K.U. caused by nature (genes), nurture (environment), or both?

Both genes and environment. Like many diseases, there is a genetic component (lacking the protein to breakdown Phenylalanine), but altering the environment appropriately (consuming a phenylalanine-free diet) prevents the disease from manifesting.

Compare the functions of the Visuo-Spatial Sketchpad with the Phonological Loop.

Both the Visuo-Spatial Sketchpad and Phonological Loop are part of Working Memory. The Visuo-Spatial Sketchpad is used for visual information (like schedules and maps) whereas the Phonological Loop is used for verbal information (words and numbers). Modality is not the way information is acquired, so whether numbers are heard (echoic) or seen (iconic memory), they will go to the phonlogical loop.

For two siblings, with genetic predispositions to depression, one child ends up good looking and receives more attention and affection, and the other ends up ugly and thereby is more isolated from society. What would account for the second child becoming depressed, nature or nurture?

Both. Nature in the sense of genetic predisposition as well as unfortunate aesthetic genes, nurture in the sense that the people in the surrounding environment did not give the child the same sort of attention and privileges.

Compare bottom-up and top-down processing.

Bottom-up: Stimulus influences our perception. Data driven and no preconceived knowledge is used, thus integrates stimuli slower. Top-down: Using background knowledge to influence perception. Theory-driven, it is quicker, but more prone to mistakes.

Later psychoanalytical theories have given more emphasis to interpersonal, sociological and cultural influences. Carl Jung preferred to think of libido as psychic energy in general. How did Jung define the ego and elements of the theory?

Carl Jung identified the ego as the conscious mind. He divided the unconscious mind into the *personal unconscious* (=Fruedian unsconscious) and the *collective unconscious*, which is a powerful system shared among all humans, considered to be a residue of experiences of early ancestors.

Describe Piaget's pre-operational stage

Children ~2-7 years - characterized by symbolic thinking (including ability to speak), egocentrism and centration (tendency to focus on only one aspect of a phenomenon). Concepts of conservation and pretend-play also develop.

There are ten personality types organized into 3 clusters. What are these clusters?

Cluster A - Odd and eccentric (paranoid, schizotypal, schizoid) Cluster B - Dramatic, emotional and errate (antisocial, borderline, narcissistic, histrionic) Cluster C - Anxious and fearful (avoidant, dependent, obsessive-compulsive)

After living with a depressed roommate for months and not scoring well on the LSAT, Jamarcus starts to develop depression himself. Could co-rumination have been a factor? If so, how?

Co-rumination is definitely a possible factor. Living with a depressed roommate, and after failing, Jamarcus and his roommate both may have sulked, and Jamarcus could have adopted some of his roommate's tendencies and attributions.

Define cognitive dissonance

Cognitive dissonance is the discomfort felt when holding two or more conflicting cognitiosn (ideas, values, beliefs, etc.) - can lead to alterations in attitudes or behaviours, which are done in order to reduce that dissonance

Substance use can lead to problems such as substance induced disorders. What falls under this category?

Conditions caused by substances that can range from substance induced mood disorders (mania, depression), disorders relating to anxiety, sleep, sexual function, even psychosis

What type of light do cones detect?

Cones detect colour and detail. There are three types, named for their wavelengths - short cones (S, blue light), medium cones (M, green light) and long cones (L, red light)

Differentiate between conformity, compliance and obedience

Conformity is how we adjust our attitudes and behaviours in order to go along with the group. Compliance is doing as you are asked even when you don't want to. (e.g. paying taxes) Obedience describes how we obey authority and follow order - does not involve cognitive factor that conformity does. (e.g. Nazism)

What is the definition of conformity?

Conformity is the tendency of people to bring their behaviour in line with group norms.

How can we define consciousness?

Consciousness can be described as one's level of awareness of themselves and their environments. Can be influenced by many factors including drugs. There are many stages of consciousness.

What is conversion disorder?

Conversion disorder (formerly hysteria) is characterized by unexplained symptoms with neurological basis that affect voluntary motor or sensory functions. Usually begin after something traumatic or stressful and develops over time - e.gs include paralysis or blindness without evidence of neurological damage. Individuals may be unconcerned about the symptom - la belle indifférence

What are binocular cues? Provide examples.

Cues about depth information derived from the use of both eyes. Examples include: Stereopsis (2 slightly diff images on retina), Eye convergence, Retinal disparity (the difference in image location seen by both eyes; ~2.5in) Yielding depth

What are monocular cues? Provide examples.

Cues provide depth information when viewing a scene with one eye. Examples include: Motion parallax (relative motion) Relative size Interposition Relative height Lighting, shading and contours Size constancy Shape constancy Colour constancy

Compare: - Deductive reasoning - Inductive reasoning

Deductive reasoning (top-down) - starts from a set of general rules and draws conclusions from info given Inductive reasoning (bottom up) - create a theory via generalizations - starts with specific instances and draws conclusions from them

What are the physiological effects of Depressants? What are some examples?

Depressants are drugs that lower the body's basic functions and neural activity, i.e. decreased CNS activity, reaction time, processing speed, heart rate and blood pressure. E.g. benzos, barbituates, alcohol

In what ways is comparing Depression and a common cold appropriate? In which ways is it inappropriate?

Depression is by far the #1 reason for reaching out to mental health services, so its prevalence in the mental health community is similar to a cold's prevalence. However, this comparison can trivialize depression, since common colds are often recovered from without outside help.

What are some of the emotional behaviour effects of stress?

Depression, anger, anxiety/fear and addiction

What are the coping mechanism types for cognitive dissonance?

Described from perspective of smoker: 1) Modifying - modifying the cognitions; "i don't really smoke that much" 2) Trivialize - trivializing/making less important their cognitions - "evidence is weak that smoking causes cancer" 3) Add - adding more cognitions - "i exercise so much it doesn't matter I smoke" 4) Denying the cognitions - denying any relations between the cognitions - "there's no evidence smoking and cancer are linked"

A man comes into the ER room wearing steel-toed boots, a mesh hat and a RAM 1500 t-shirt, and is carrying his detached finger with him in a toolbox. Is it more likely that he is a construction worker, or a truck-driving construction worker? How might this be an example of the Conjunction Fallacy?

Despite any context clues, it is statistically more likely that the patient falls under just the label of "construction worker" than both "construction worker" and "truck driver". This is a clear example of the Conjunction Fallacy.

What are some ways people can cope with stress?

Develop a sense of perceived control over a situation Social support Nurturing an optimistic attitude

How does the auditory system break down complex sound waves into its component parts?

Different sound waves of different frequencies travel different distances in the cochlea and move different hair cells.

Hormones can also be classified by target tissue. Differentiate between *direct hormones* and *tropic hormones*

Direct hormones - secreted and act directly on target tissue - e.g. insulin released by pancrease induces glucose uptake by muscles. Indirect hormones - require intermediary action - e.g. GnRH stimulates LH and FSH

Differentiate between direct and indirect therapy. Which approach typically subscribes to which one?

Direct therapy refers to treatment that acts directly on the individual such as medications and periodic meetings with the psychologist. Indirect therapy aims to increase social support by educating and empowering family and friends of affected individual. The biomedical approach uses direct therapy; biopsychosocial uses both.

Differentiate between drive-reduction theory and the theory that motivation is based on needs.

Drive-reduction theory explains that motivation is based on the goal to eliminate uncomfortable stress. Need based theories state that motivation is explained by how we allocate energy and resources to satisfy our needs.

Describe the drive-reduction theory of motivation

Drives are internal states of tension that induce particular activity. The drive-reduction theory states drives help humans survive by creating an uncomfortable state ensuring motivation to eliminate this state or relieve internal tension. Primary drives (need for food, water, warmth) motivate us to sustain bodily temp in homeostasis. Homeostasis is controlled by negative feedback.

Considering the proximity of the receptors for different flavors. How does the Labelled Lines Model account for the 5 flavors not mixing?

Each one of the specialized taste cells has dedicated axons that remain separate all the way to the brain and synapse at dedicated spots in the brain without mixing.

How does a taste bud distinguish between different tastes?

Each taste bud has all the different types of cells specialized to each of the tastes. They all have dedicated axons that lead to the brain and remain separate all the way, and synapse at different parts of the brain. (This is known as the labelled lines model)

What is encoding?

Encoding refers to the process of putting new info into memory.

The adrenal medulla is responsible for production of sympathetic hormones epinephrine and norepinephrine (catecholamines) - specialized nerve cells in the medulla allow for direct release of these hormones into circulatory system. What do each do?

Epinephrine increases breakdown of glycogen -> glucose (glycogenolysis) and increases basal metabolic rate. Both hormones increase heart rate, dilate bronchi, and alter blood flow to certain internal organs. In sympathetic response- vasodilation of blood vessels to heart, lungs, skeletal muscle and brain to increase blood flow to these organs; vasoconstriction of vessels to decrease blood flow to the gut, kidneys and skin

What are some ways people manage stress?

Exercise and meditation Religious beliefs/faith Cognitive flexibility to change perspective

The pancreas has exocrine and endocrine functions. What is its exocrine function?

Exocrine tissues in pancrease secrete substances directly into ducts - numerous digestive enzymes

Compare Exogenous vs. Endogenous Cues.

Exogenous cues are external to our goals, will capture attention anyways (loud noise, bright colours). Endogenous cues are more internalized and require higher order thought (seeing an arrow and knowing it means to look/go that direction).

True or false: with age, fluid intelligence tends to increase or remain stable, while crystallized intelligence decreases dramatically

FALSE: crystallized intelligence remains stable or increases with age, while fluid intelligence tends to decrease

True or false: the id is responsible for our system of right or wrong, which substitudes for parental rewards and punishments.

FALSE: the *superego* is responsible for our system of right or wrong, which substitudes for parental rewards and punishments.

True or False? At the end of each projection that the olfactory bulb sends through the cribriform plate to the olfactory epithelium are receptors that sensitive to many molecules each.

False. At the end of each projection that the olfactory bulb sends through the cribriform plate to the olfactory epithelium are receptors that sensitive to ONLY 1 MOLECULE each.

True or False. Attitudes are something innate and unchangeable as they are closely intertwined with one's personality.

False. Attitudes are defined as "learned tendencies."

True or False? Object Permanence describes how older children can know that two cups hold equal volumes of water, even if the cups are different shapes, if the water is poured in front of them.

False. CONSERVATION describes how older children can know that two cups hold equal volumes of water, even if the cups are different shapes, if the water is poured in front of them.

True or False. The sooner a reward is given after an accomplishment/action, the less likely it is to occur again. Behavior is best rewarded at random and inconsistently as in variable-ratio conditioning.

False. The sooner a reward is given after an accomplishment/action, the more likely it is to occur again.

True or False? There is a certain personality type that is more likely to obey and conform than others.

False. There isn't a certain personality type that is more likely to obey and conform than others. However, different socioeconomic and cultural groups may be a little more likely.

True or false: Sodium channels in the rod cells require GMP to be bound in order for them to be open and allow flow of Na+ ions into the cell.

False. They require cGMP to be bound; conversion of cGMP to GMP by phosphodiesterase (PDE) causes a decline in cGMP concentration, closing the sodium channels.

True or False? To have an effect, hormones must be very concentrated in the blood (almost as concentrated as White Blood Cells).

False. To have an effect, hormones can be at very low concentrations in the blood (picograms/mL can be enough!)

True or false: Aging usually leads to significant memory loss.

False: contrary to popular belief, aging does not do this as many elderly retain vivid semantic and prospective memories.

True or false: Hypnosis has had little to no success in real world medicine or therapy.

False: hypnosis has been used successfully for pain control, psych- therapy, memory enhancement, weight loss, smoking cessation - the success or effectiveness, however, highly depends on how willing the subjects personality is + lack of skepticism

True or false: the tympanic membrane is part of the middle ear

False: it is considered part of the external ear

True or false: Between these three, semantic encoding is the weakest form of encoding: - Semantic encoding - Visual encoding - Auditory encoding

False: semantic encoding is the strongest while visual is the weakest.

True or false: when someone tells you their IQ score, they are telling you their practical intelligence (from Sternberg's 3 intelligences)

False: the IQ test measures what would be analytical intelligence on Sternberg's theory (or linguistic and logical-mathematical on Gardner's) The Stanford-Binet IQ test is: IQ=mental age/chronological age x100

True or false: the image projected on the retina is upright

False: the image is inverted

True or false: extremely vivid and emotional memories are not susceptible to memory reconstruction.

False: these memories (flashbulb memories) are indeed still susceptible to memory reconstruction

True or false: during meditation the EEG sees beta waves from the brain

False: theta and alpha waves are seen, resembling Stage 1 of sleep.

True or false: when we are awake, cortisol levels tend to be lower

False: when we are awake, there is a physiological level of arousal and cortisol levels tend to be HIGHER.

If Freddie has a strong attraction to Hannah Montana, how might he use the Reaction Formation Defense Mechanism to deal with this?

Freddie might actively voice disgust with her and say that he hates her music. In Reaction Formation, an individual expresses the opposite emotion to the one they actually have.

Differentiate between free recall, cued recall and recognition.

Free recall is when you recall information without any cues or hints. Cued recall is when you are given some form of a cue to recall a piece of information, e.g. when recalling the word 'planet' from a list and you are given 'pl_____' Recognition is the process of merely identifying a piece of info that was previously learned - far easier than recall itself.

There are several types of anxiety disorders. Describe Generalized Anxiety disorder

Generalized anxiety disorder (GAD) - defined as disproportionate and continuous feeling of anxiety/worry and tension about many things for at least six months. People tend to be very tense with an unclear source. Physical symptoms may include fatigue, muscle tension, sleep problems. 2/3 patients are female.

Describe glucocorticoids and how they work + e.gs

Glucocorticoids regulate blood glucose levels and raise them via gluconeogenesis and decreasing protein synthesis. Examples are cortisol and cortisone - cortisol is responsible for increasing glucose levels for fuel during stress and fight-or-flight modes. Glucocorticoid release is under control of ACTH

T3 and T4 are synthesized by iodination of AA tyrosine in the follicular cells of the thyroid. The numbers 3 and 4 correspond to the number of iodine atoms attached to each tyrosine. Increased levels of T3 and T4 leads to cellular respiration - what does this entail?

Greater amounts of T3 and T4 leads to greater amount of protein and fatty acid turnover by speeding of synthesis and degradation. High plasma levels of thyroid hormones leads to decreased TSH and TRH synthesis - negative feedback in excess of T3 and T4

A group of closet racists and a group of closet feminists are placed in a room to discuss issues about racism for an hour. After the discussion, it was found that in the first group, members became overt and more racist than they were before, whereas the other group members became even less so. What explains this?

Group polarization - tendency for group ideas to shift more to an extreme than individual ideas of members within the group.

Group interactions can shape an outcome. What is group polarization?

Group polarization is a phenomenon in which group decision making amplifies original opinions of group members. Group ideas have a tendency to polarize towards an extreme, more so than individual ideas or inclinations of members within a group. Some factors: -All views do not have equal influence - viewpoint shared by majority -Arguments made tend to favour popular view, criticism is directed to minority view (confirmation bias)

Group interactions can shape an outcome. What is groupthink?

Groupthink is the social phenomenon where the desire for harmony and minimizing conflict results in a group of people potentially coming to a poor decision. The desire to eliminate conflict drives consensus decisions without presenting of alternative views/ideas, and the desire to agree causes a loss of independent critical thinking. Many factors influence groupthink, including: illusion of invulnerability, collective rationalization, illusion of morality, pressure of conformity, self censorship, illusion of unanimity, mindguards

Compare and contrast hueristics and algorithms in terms of processing speed and guarantee of correctness.

Heuristics are mental tricks used to break complex problems into simpler problems using mental tricks, but do not guarantee right answers. Algorithms are methodical approaches that are guaranteed to get the correct answer, but can take a very long time.

A deficiency of iodine or inflammation may result in hypothyroidism - what characterizes this condition?

Hypothyroidism is characterized by lethargy, decreased body temp, slow respiratory and heart rate, weight gain, cold intolerance.

Put the Auditory Ossicles in order from first to vibrate to last to vibrate? I. Incus II. Malleus III. Stapes (A) I > II > III (B) II > I > III (C) III > II > I (D) III > I > II

II > I > III malleus -> incus -> stapes

Why is answer choice B wrong in the following question: Two siblings could be born with the same combination of genes that can lead to depression, but the environment only activates those genes for one of the siblings. Which of the following scenarios is this most like? (A) Ben and Chrissy both have a dream to win a reality TV show, but only Ben achieves this dream. (B) Devon and Mike grew up having very different looks, and because Devon was more handsome, he received more positive attention. (C) Ashley and Alan both have a predisposition for panicking under stress, and Alan has a panic attack after he gets in a car accident. (D) Lauren and Desi grew up with very different lifestyles, so that only Lauren enjoys working outdoors.

In this answer choice (B), one sibling ends up receiving more attention and affection from the surroundings and so may end up growing up happier and more optimistic, but this does not suggest any predisposition to depression or any sort of mental disorder, thus assuming the other child would become depressed would not be entirely accurate. If a predisposition was mentioned, then (B) would have more of an option.

What is L-DOPA? How is it useful for Parkinsons?

L-DOPA is a precursor that is converted to dopamine once in the brain - it is therefore useful for partially managing Parkinsons by replacing what is lost due to the disease.

Parts of the eye: cornea

Light passes through the cornea first, which gathers and focuses incoming light. Entering light is bent with an index of refraction = 1.4 (while air = 1.0)

Maslow's Hierarchy of Needs is the most well known motivation theory based on needs, and breaks down needs into categories on a pyramid. Describe his theory and hierarchy.

Maslow's Hierarchy of Needs - classifies needs into five groups of different importance on a pyramid, with the bottom being the most important. His needs, in order of importance, were: - Physiological (breathing, food, water, air, sex, homeostasis) - Safety (security of: body, employment, health, property) - Love/Belonging (friendship, family, intimacy) - Esteem (self-esteem, confidence, respect) - Self-actualization (morality, creativity, spontaneity, problem-solving, accomplishment)

Describe the term and what kind of cue it is: motion parallax

Motion parallax is relative motion - it is a monocular cue. When looking at something far while moving, it appears to move slow, whereas something nearby or adjacent seems to be moving fast.

Cluster B (dramatic/emotional) is defined by four types of personality disorder. Describe narcissistic personality disorder

Narcissistic personality disorder - characterized by sense of grandoise and self importants, feelings of entitlement and constant need for admiration and attention. Ego-centric.

What does the Nature versus Nurture debate claim about motor development.

Nature: Since kids all around the world and blind kids all have similar timelines, it may not be learned from watching/nurture. Nurture: Allowing more space and time with parents to develop motor skills and practice can help.

What kind of light do rods detect?

Only light and dark - they have one pigment, which is rhodopsin - low sensitivity to detail but permits night vision

What mechanistically differentiates PTSD from other anxiety disorders?

PTSD can have a clear trigger that causes the onset of the disorder, while others have more ambiguous or trivial beginnings.

There are several types of anxiety disorders. Describe Post-Traumatic Stress Disorder (PTSD), and the sort of symptoms it has (intrusion, avoidance, negative-cognitive, arousal).

PTSD is a stress anxiety disorder that occurs after experiencing or witnessing a traumatic event. Unlike other anxiety disorders, it usually has a trigger to onset the disorder. PTSD has intrusion, avoidance and negative cognitive and arousal symptoms: Intrusion symptoms include recurrent reliving the event through flashbacks, nightmares and prolonged distress. Avoidance symptoms include deliberate attempts to avoid memories, people, places, objects etc. associated with the trauma. Negative cognitive symptoms include inability to recall the key features of the incident, negative mood and world views, feeling distanced. Arousal symptoms include increased startle response, irritability, anxiety, destructive or reckless behaviour, insomnia.

There are several types of anxiety disorders. Describe panic disorders

Panic disorders consist of repeated panic attacks - symptoms of a panic attack include fear and apprehension, trembling, sweating, hyperventilation, and a sense of impending doom. Panic attacks tend to be sudden bursts of short-lived but very severe, intense episodes.

Peptide hormones are charged while steroids aren't (derived from nonpolar molecules) - what does this entail about their water solubility and travel through the bloodstream?

Peptide hormones can travel through the bloodstream without carriers because they are water soluble. Steroid hormones are nonpolar and thus not soluble in water - they require protein carriers to travel through the bloodstream. They are generally inactive when attached and must dissociate from the carrier protein to function. Carrier proteins can be specific or nonspecific.

Peptide hormones are charged - how do they function if they cannot pass through the plasma membrane (due to charge)?

Peptide hormons cannot pass through the plasma membrane and hence function as a *first messenger* and bind to the receptor (usually G-protein coupled) to release a second signal called a *second messenger*. At each step there is a possibility of amplification. The connection between the hormone and the effect of its second messenger - referred to as *signalling cascade*. Common peptide hormones are insulin, ADH; common second messengers are cAMP, IP3 and Calcium

Symptoms of schizophrenia include positive and negative symptoms. What are examples of each?

Positive symptoms refer to presence of symptoms such as delusions, hallucinations, disorganized thought, speech or behaviour. They have a psychotic dimension (delusions/hallucinations) and a disorganized dimension (disorganized activity). Negative symptoms refer to the absence of normal or desired behaviour, such as disturbance of affect or avolition (lack of engagement in goal-driven actions)

Each of the tropic hormones causes release of another hormone from an endocrine gland that has a negative feedback effect. What does this mean about receptors on the hypothalamus and pituitary?

Receptors for end hormones like cortisol must be present on the hypothalamus and pituitary for negative feedback to be possible. CRF from hypothalamus causes release of ACTH from pituitary gland - ACTH causes the adrenal cortex to release cortisol. When cortisol levels get too high, it must have negative feedback capabilities - therefore receptors for cortisol must be present on the hypothalamus and pituitary.

Describe the following retrieval cues: Serial position effect

Retrieval cue referring to how learning lists. Learners will have much higher recall for the first and last few items on a list than any other - tendency to remember early and late items is known as the *primacy* and *recency* effect (respectively)

Describe the following retrieval cues: State-dependent effect

Retrieval cue referring to people who learn facts or concepts in an altered state of mind, will recall the information best when in that state of mind.

What is retrieval?

Retrieval is the process of demonstrating that something learned has been retained. Many think of it as recall.

Compare retroactive and proactive interference in terms of memory.

Retroactive interference is when some new piece of information makes it harder to recall previously learned information/memories. Proactive interference is when something learned in the past interferes with learning or retrieving something learned after.

Differentiate retrograde and anterograde amnesia.

Retrograde amnesia - loss of previously formed memories Anterograde amnesia - inability to form new memories

Describe the second step of the phototransduction cascade. Rhodopsin has changed it's shape, and there's a molecule of interest attached to it. What happens?

Rhodopsin changes shape after 11-cis retinal -> all trans retinal. A G-protein molecule, Transducin, is attached to rhodopsin, and subsequently breaks off. Transducin has an alpha, beta and gamma subunits, and the alpha subunit binds to PDE (phosphodiesterase).

What happens when light hits a rod cell? Is it turned off or on?

Rod cells are normally turned on, in the absence of light. So when light hits a rod cell, it turns it off.

What happens when light strikes a rod cell in the rhodopsin proteins? How are they turned off?

Rod cells have disc like structures within, that contain rhodopsin proteins. Rhodopsin contains a small molecule retinal, which exists in a particular conformation called 11-cis retinal. When light hits rhodopsin, it causes the 11-cis retinal molecule to change conformation to become all trans-retinal, and subsequently rhodopsin also changes shape. Rhodopsin has a molecule called transducin, (a G-protein which has α, β and γ subunits) that then breaks off, and the alpha subunit goes and binds to a protein phosphodiesterase (PDE) on another part of the disc. PDE converts cyclic GMP to GMP. The increase in [GMP] results in inability of Na+ channels along the cell to remain open, as they require cGMP to be bound to remain active. As less sodium enters the cell, the cell hyperpolarizes and causes the rod cells to turn off. These will be divided into other cards - look out for them!

When you walk out from the bright sunlight into a dark room, you are unable to see at first, but after a few minutes your eyes adjust and you can begin to see clearly. What causes this on a molecular level?

Rods account for dark and light (or B/W) vision. Rods have slow recovery or adjustment times - in bright light, they are hyperpolarized to allow activation of bipolar cells; for them to return to resting membrane potential and fire another action potential, it takes more time than it does for cone cells. Hence, when you go into a dark room from bright, it takes time for rods to reactivate to be able to clearly see in the dark

The retina has two types of photoreceptors in particular- what are they?

Rods and cones

Compare Assimilation and Accommodation, in terms of mental Schema.

Schemas can be defined as frameworks we create in order to organize and understand new information (e.g. schema for 4 legged animals). Piaget theorized new information is processed via adaptation, which has two complementary processes: assimilation and accomodation. Assimilation is the process of classifying new information into existing schemas. Accomodation is the process by which the EXISTING schemas are modified to incorporate new information.

Cluster A (Odd and eccentric) is defined by three types of personality disorder. Describe schizoid personality disorder

Schizoid personality disorder is a pervasive pattern of emotional detachment from social relationships + restricted emotional expression Little social interactions + poor social skills

Cluster A (Odd and eccentric) is defined by three types of personality disorder. Describe schizotypal personality disorder

Schizotypal personality disorder refers to a pattern of odd or eccentric thinking - individuals may have ideas of reference (similar to delusions of reference) as well as magical thinking (supersticious, belief in clairvoyance)

An individual experiences symptoms of major depressive disorder, but for some reason only during the winter season. What sort of disorder might this be categorized as? How might this be treated?

Seasonal affective disorder (SAD). Best explained as major depressive disorder with seasonal onset, with symptoms present only in the winter months. Believed to potentially be related to abnormal melatonin metabolism, and often treated with bright light therapy (patient exposed to bright light for specified amount of time each day).

What is sensory memory?

Sensory memory is a temporary register of all the senses your body is taking in. The most studied are iconic memory (visual) and echoic memory (auditory)

What are the two important classes of steroids in the body?

Sex hormones - estrogen, progesterone, androgens Adrenal cortex steroids - cortisol, cortisone, aldosterone

What is the benefit of basilar tuning?

Specific frequencies send specific signals allowing the brain to distinguish between different sounds of high or low frequencies. Otherwise, if all hair cells responded to all frequencies, one large signal would be sent to brain without ability to distinguish.

When eating spicy foods, people can feel pain as their TrpV1 receptors are activated. Why can capsacin and similar chemicals activate these receptors?

Spicy foods contain chemical molecules like capsacin which bind to TrpV1 receptors in your tongue, causing it to fire an action potential, which causes the brain to interpret it as pain and heat. Over time, the receptors become desensitized to capsacin.

Describe the sympathetic NS vs. parasympathetic NS in terms of: - Pupil dilation - Salivation - Breathing (respiratory) rate - Heart rate - Glucose release (blood sugar) - Adrenaline release - Digestion

Sympathetic NS: Pupils dilate; decreased salivation and digestion; increased breathing and heart rates, glucose release/blood sugar, and adrenaline/epinephrine release. Parasympathetic: Pupils constrict; increased salivation and digestion; decreased heart and breathing rates, adrenaline release and glucose release (or increased glucose storage)

Why is the hypothalamus referred to as the "control center"?

The Hypothalamus plays a key role in integrating the CNS and Endocrine System because of its duality as an endocrine gland and as part of the forebrain. Because of this, the hypothalamus can be considered the Control Center.

Describe Frued's element of the Id

The Id is the most unconscious part of our mind that develops at birth. It operates under a *pleasure principle* which demands instant gratification. The *primary process* is the id's response to frustration, which is to seek satisfaction immediately.

You are really craving ice cream. Describe how the Id, Ego, and Superego might interact within your mind as you face this temptation.

The Id wants immediate gratification and would drive you to just eat the ice cream NOW. The Superego is moral oversight and represents the values of society, which would tell you to never eat ice cream because it is not good for your body. The Ego acts as a mediator would balance out the two, resulting in a compromise where you eat some ice cream after patiently waiting for it.

What is the Just World Phenomenon?

The Just World phenomenon is the idea that the universe is fair and people must get what they deserve. "Good things happen to good people, while bad things happen to bad people". In terms of Milgram's experiment, some of the participants who felt ashamed for what they did still justified their actions somewhat by sort of blaming the victims, stating if they got more answers correct and were smarter, they wouldn't have gotten shocked as much.

Draw or visualize an example of The Law of Continuity. Describe this law.

The Law of Continuity - lines are seen as following the smoothest path.

Draw or visualize an example of The Law of Pragnanz. Describe this law.

The Law of Pragnanz states that reality is usually reduced to its simplest form. In this image, you see five circles instead of more complex potential shapes.

Draw or visualize an example of The Law of Proximity. Describe this law.

The Law of Proximity states that objects that are close to each other are usually grouped together.

Draw or visualize an example of The Law of Similarity. Describe this law.

The Law of Similarity - items or objects that are similar are grouped together.

Describe the Lazarus theory of emotion. How is it different from the Schachter-Singer theory?

The Lazarus theory of emotion proposed that the experience of emotion depends on how the experience is cognitively appraised (where you label the situation). It is different from the Schachter-Singer theory because once an event happens, the situation is labelled by the brain, and depending on that label comes the emotional response. So if the situation is labelled as bad or frightful, the emotion experience thereafter is negative and a physiological response occurs (simultaneously).

Right now, you are preparing for the MCAT. Is the MCAT a Well-Defined or Ill-Defined problem, and why?

The MCAT is a well-defined problem, because it has a clear beginning and end. Especially with the structure and organization of the MCAT Self Prep eCourse! ;) An Ill-defined problem lacks that clarity.

Stanley Milgram was inspired by his background (Jewish parents who immigrated to the US) and by the Holocaust to conduct his experiment regarding obedience. Describe his experiment.

The Milgram experiment was conducted to observe the obedience of participants who were asked to give an individual for answering questions wrong. Individuals did as they were told and administered high level shocks in order to obey the authority, despite having to give up to 'lethal' shocks. It found that stark authority usually overuled peoples morals and people would go to any extent under authority.

Abnormalities in neural pathways for certain NTs may cause increased or decreased activity in certain parts of the brain, leading to depressive symptoms. Discuss these pathways: - Raphe system - Locus Coeruleus - VTA pathway

The Raphe system - pathway begins in the Raphe nuclei of the brainstem, responsible for secreting serotonin into projections leading up to the cerebrum (including frontal lobe and limbic system) - the pathway seems to be abnormal in patients with depression. Locus Coeruleus - also begins in the brainstem, releasing norepinephrine into the cerebrum - also abnormal in patients with depressive disorders VTA - in the brainstem - supplies much of the dopamine to the brain via the mesocorticolymbic pathway - also abnormal in depressive patients. Medications that affect these different NTs often better some of the symptoms of depressive disorders.

The *Rorschach inkblot test* and *thermatic apperception test* both are used to identify individual undesired feelings via projection as a defense mechanism. Describe the tests.

The Rorschach inkblot test - relies on assumption that the client projects his or her unconscious feelings onto the shape Thermatic Apperception test - series of pictures presented to client who is asked to make up a story for each - will elucidate client's own unconscious thoughts and feelings.

Describe the Schachter-Singer theory of emotion. (hint: cognitive appraisal)

The Schachter-Singer theory (aka cognitive-arousal theory or two-factor theory) states that BOTH arousal and the labelling of arousal based on the environment must occur in order for an emotion to be experienced. E.g. "I am excited because my heart is racing and everyone else is happy" This theory uniquely incorporates cognitive appraisal into causation of emotion

What does the activation-synthesis theory of dreams state?

The activation-synthesis theory states dreams are caused by widespread, random activation of neural circuitry in our brainstem - this activation can mimic incoming sensory information, and may consist of stored pieces of memories, current or previous desires, and met or unmet needs. By this theory, dreams have no prominent meaning.

What happens when a benzene molecule (or aromatic compound) enters a nasal passage and hits one of the receptors on a nerve projection?

The benzene ring hits the receptor - those sensitive to benzene will trigger a cascade of events and fire an action potential into a particular location in the olfactory bulb called a glomerulus. From there, they synapse into a mitral (or tufted) cell, which projects the signal to the brain.

Describe Jung's *collective unconscious* and what elements it has

The building blocks of the collective unconscious are images of common experiences, referred to as *archetypes* - examples of archetypes: The *persona* - a personality mask we wear in public that is adaptive to social interactions The *anima* (feminine) and *animus* (masculine) - referring to sex-inappropriate qualities - feminine qualities in males, masculine qualities in females The *shadow* - appearance of socially reprehensible and unpleasant thoughts, feelings, emotions in our consciousness.

What is sensory adaptation?

The change in the sensitivity of your perception of a sensation Senses of hearing, touch, smell, even proprioception (sense of balance) all adapt to changes in perception by desensitizing

When at a rock concert, your friend whispers something in your ear and you have no clue on Earth what he said. However, when he whispered the same thing the next day in the library, you had no issues understanding what he said. What concept explains this?

The concept of JND (just noticeable difference). By Weber's Law (ΔI/I=K), the threshold for the JND would be very different compared to the surroundings of the two environments. Relationship between intensity and incremental threshold is linear.

What is the relative density and location of the rod and cone cells in a human eye?

The cones are very densely populated and centered in the fovea, while scarcely present in the periphery of the retina. The rods are densely populated in the periphery of the retina, but decline rapidly when approaching the fovea.

Nativists believe in a certain time frame between the ages of 2 and puberty for learning language, beyond which later training is largely ineffective. What is this timeframe called?

The critical period - period of time in which a child is most able to learn a language. Theoretically, LAD only operates during this period.

Describe Frued's element of the superego

The ego and superego both have conscious and unconscious elements. The superego also aims to achieve desires, but unlike the id (which desires basic needs), the superego has refined and focused desires on the ideal self - personality perfectionist that judges our actions and responds with pride or guilt. Two elements: the *conscience* - collection of punishable improper actions from childhood; the *ego-ideal* - proper actions rewarded from childhood. These eventually transform into a system of right or wrong.

You probably noticed that when you spun around too much like an idiot when a child, you got pretty dizzy after. What goes on in the vestibular system when that happens?

The endolymph in the ear canals doesn't stop moving right when we do when we're spinning around vigorously and then stop. As a result, the shifting endolymph continues to send signals and action potentials to your brain that you are still moving, when when at halt. This results in dizziness. When the fluid eventually stops moving is when the dizziness stops.

The olfactory bulb is a bundle of nerves that sends thousands and thousands of nerve projections through the cribriform plate into the olfactory epithelium. What is at the ends of these projections?

The ends of these nerve projections have tiny receptors that are each sensitive to only one molecule each. This accounts for how we smell distinct odors.

Describe the evolutionary approach of motivation

The evolutionary approach is based on the instinct theory - people are driven to do certain behaviours based on evolutionary programmed instincts. Described motivation in reference to Darwinian evolution. William James was the first to write about instincts.

Describe the foot-in-door phenomenon on how behaviour influences attitude.

The foot in door phenomenon states we are much more likely to do a large, attitude changing task if we agree to perform a small one first. This is one way people get 'brainwashed' into doing things. "foot in door" or "dipping feet into water". E.g. trying our SARMS before going to full-fledged steroids; gateway drugs

What is the general intelligence (G factor) theory?

The general intelligence theory proposes there is one underlying intelligence accounting for our mental abilities and capabilities, and ability in one area = higher ability in another

When you eat a piece of cake, how do the glucose molecules interact with taste buds?

The glucose molecule binds to a receptor for glucose in the sweet cell of a taste bud, which triggers a cascade and fires an action potential all the way to the brain. Also: for sweet tastes, the molecule binds to a GCPR and causes the G-protein to dissociate from the receptor, beginning the cascade.

Describe the hierarchal model of semantic memories and spreading activation.

The hierarchal model (which is the old model) was a simplistic hierarchal network of things into general categories.

What is the function of the hippocampus in the limbic system?

The hippocampus works to form new memories - converts short-term memories into long-term memories

Describe the *humanistic theory* (or phenomenological)

The humanistic theory takes a person-centered approach in stating individuals have free will and the ability to strive towards self-actualization (which remember, is max potential in Maslow's hierarchy!) The theory states we are inherently good and strive to self improve. Maslow was the first humanist.

The hypothalamus connects to the pituitary gland through a stream of blood vessels to release hormones that bind to receptors in the pituitary, triggering release of other hormones. What is the name of the blood vessel system?

The hypophyseal portal system. The hypothalamus sends tropic hormones through the hypophyseal portal system to the anterior pituitary gland, where they bind to receptors and signal release of other hormones.

Describe the role of the hypothalamus and how it regulates hormones and maintains homeostasis.

The hypothalamus is the control center that links the CNS and endocrine system - located in the forebrain and can have organism-wide effects. The hypothalamus controls the pituitary through paracrine hormones (regionally acting) into a hypophyseal portal system, and can receive input from a variety of sources. It regulated the release of hormones and maintains homeostasis via negative feedback.

What is the role of the hypothalamus in the limbic system?

The hypothalamus regulates the autonomic nervous system - fight/flight or rest/digest - via secreting hormones into your body (epinephrine, norepinephrine, adrenaline)

Alfred Alder also formed a psychoanalytical theory - he was the originator of the *inferiority complex*. How did his theory describe personality?

The inferiority complex refers to individual's sense of incompleteness, imperfection and inferiority (physically & socially). Alder's theory stated striving for superiority enhances and drives personality.

Sensory adaptation can protect your ears (via the tympanic reflex) from damage during a long fireworks display. How does this work?

The inner ear muscle contracts after an increased, sustained stimulus, decreasing ossicle vibration and downstream sensitivity.

B. F. Skinner proposed that operant conditioning and reinforcement account for an infants ability of language development. Which theory does this refer to?

The learning (behaviouralist) theory of language development. Over time infants perceive sounds that are reinforced as having value, whereas those that aren't do not. Does not explain how children can learn new words or form sentences they haven't heard before

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the Learning theory

The learning theory of attitudes states that our attitudes are developed from different forms of learning - can be influenced by direct contact, direct instruction from others, subjective norms, and/or classical, operant conditioning or observational learning.

What is the absolute threshold of a sensation?

The minimum stimulus needed to activate a sensory system and reach the CNS - it is a threshold in sensation but not perception. A stimulus below this would not reach the CNS. It can also be described as the minimum intensity of a stimulus to be able to detect a stimulus ~50% of the time - lowest level of a stimulus we can generally detect.

The hypothalamus also releases PIF (prolactin-inhibiting factor) into the anterior pituitary - what is different about this hormonal release?

The other hormones release all stimulated the release of their respective hormones. However, PIF (which is actually dopamine) inhibits the release of Prolactin secretion (stimulates mammary glands in females to produce milk)

What is the purpose of the otolithic organs (utrical and saccule)?

The otolithic organs help determine the acceleration and head positioning. They have calcium carbonate crystals attached to hair cells. These crystals pull on the hair cells, depending on our head positioning, which results in an action potential, allowing us to detect acceleration and position.

How are sound waves transmitted along in the inner ear?

The oval window (or eliptical window) is attached to the cochlea. After the ear drum vibrates and the stapes causes the oval window to vibrate. This causes fluid inside to go all the way around the cochlea until reaching the tip, and flow back until it hits the circular (round) window and pushes it out. This continues to happen until the energy of the sound wave has dissipated, and hair cells inside the cochlea are being pushed back and forth, which transmits an electrical impulse via the auditory nerve --> brain.

How does the phototransduction cascade affect rod cells, the downstream bipolar and ganglion cells, and the optic nerve?

The phototransduction cascade deactivates rod cells that typically inhibit downstream cells. In response, a bipolar cell is activated, which activates a retinal ganglion cell that sends signals to the optic nerve, which finally leads to processing in the Brain.

What is the first part of sound waves hit when entering the body for transduction?

The pinna, portion of the outer ear

What does the pre-frontal cortex do in relations to emotions?

The prefrontal cortex is the anterior portion of the frontal lobes - associated with planning intricate cognitive functions - problem solving, decision making, expressing personality.

Explain the concept and mechanism of synaptic plasticity and long-term potentiation.

The presynaptic neuron releases NTs to the postsynaptic neuron, which opens channels to allow cations (Na+, Ca^2+) to flow into the postsynaptic charge. Each neuron have a surrounding membrane, with the interior having a different charge than the exterior - diff in charges called neurons potential, and the flow of ions affects that potential. Strength of synapse is measured by how much post synaptic potential changes with presynaptic stimulus. With practice, the synaptic plasticity improves at opening channels and the strength of synapse increase - this is called Long term potentiation, and this is why we can learn better with practice.

What does the problem solving theory of dreams state?

The problem-solving theory states dreams are a way to solve problems while you are sleeping - untethered by real world rules, and allow interpretation of obstacles differently than when alert and awake.

Before schizophrenia is diagnosed, a patient often goes through a phase characterized by poor adjustment called the Prodromal phase - describe this phase

The prodromal phase is exemplified by clear evidence of deterioration, social withdrawal and isolation, impairment of role functioning, peculiar behaviour, unusual experiences, and inappropriate affect.

Remaining in stress and overdrive for too long puts your body in a system of overdrive. What are some of the physical effects of stress on the reproductive system?

The reproductive system requires lots of energy, and so part of acute stress response (like fight or flight) the reproductive system is inhibited or shut down. However, with chronic stress (which accompanies psychosocial stressors) - hormones like LH and FSH, estrogen and progesterone involved in reproduction in women can be inhibited; erectile dysfunction is a problem in men with inhibited testosterone and less blood flow.

Drug addiction is highly related to the mesolimbic reward pathway. What is this pathway and what does it include?

The reward pathway is a dopaminergic pathway that includes the ventral tegmental area (VTA) or the brain which releases dopamine in response to a pleasurable stimulus, to the nucleus accumbens (NAc), amygdala, prefrontal cortex and hippocampus. The pathway counts for motivation and emotion, and positive reinforcement of substance use. Stimuli can include food, sex, social interactions, drugs, gambling, even love.

Describe the first step of the phototransduction cascade. Light hits the rod cells, what happens? (think rhodopsin)

The rod cells have membrane bound structures called optic discs which contain proteins, one of which is rhodopsin. When light hits the rod cell, and strikes rhodopsin, it causes a conformational change in a molecule within - 11-cis retinal becomes all trans retinal. Subsequently, rhodopsin also changes shape.

When it comes to behaviour influencing attitudes, what is role-playing phenomenon?

The role-playing phenomenon states that people alter their behaviour when in a new role to fit that role, which may eventually influence their attitudes and normalize that role. E.g. first time parents feel unusual at it initially but eventually develop new attitudes, "mature"; new professional behaviours in a new job, making you eventually having a new attitude

What is the sleep cycle? How does it go typically?

The sleep cycle refers to a single progression through the stages of sleep - the makeup of sleep cycle changes through the night, as early on SWS (slow wave sleep) predominates as the brain falls into deep sleep and then more wakeful states. Later at night, REM sleep predominates. The cycle goes from N1 -> N2 -> N3 -> N2 -> REM -> back to N1 and repeat.

What is the essence of the biological perspective of personality theories?

There is variation amongst biological theorists but in essence, the biological perspective holds that personality can be explained by the result of genetic expression in the brain and behaviour. The biological theory suggests that important components of personality are [[inherited]]

What does the social interactionist theory of language development state?

The social interactionist theory accounts for interplay between biological and social processes in language development. States children's have a desire to communicate with others, which drives their language development as brain circuits are reinforced through these interactions.

There are a few theories that attempt to explain how attitudes influence behaviour. Describe the social-cognitive theory

The social-cognitive theory of attitudes states people learn how to behave and shape attitudes by observing behaviours of others. According to this - behaviour is not learned by trial and error, but develops via direct observation and replication of actions. 3 factors of behaviour, personal factors and environment are not independent, but rather influence each other.

What is the purpose of the anterior, posterior and lateral/horizontal canals (aka semicircular canals)? By what mechanism do they work?

The three ear canals are at right angles to each other and each are in line with one of the axes along our head (x, y or z). The canals are filled with a fluid called endolymph, and rotations of our head along particular axes causes the endolymph in the corresponding semicircular canal to shift - allows us to sense what plane out head is rotating along, as well as strength of the said rotation. Works towards our proprioception (sense of balance and position).

Why doesn't fluid flow back around the cochlea and hit the eliptical window? Why only the circular window?

There is a membrane that runs along the length of the cochlea known as the organ of corti, which prevents this from happening. It consists of two different membranes, the basilar membrane and tectorial membrane.

A reflex is an involuntary behavioural response to a stimulus without higher cognitive input. Infants are equipped with a variety of reflexes that may help and ensure survival. Describe the following primitive reflexes that disappear with age: - Rooting reflex - Sucking and swallowing reflex - Moro reflex - Babinski reflex - Grasping reflex - Galant reflex - Swimming reflex

These primitive reflexes that disappear with age are called neonatal reflexes. Rooting reflex - baby turns its head in response to stroking of cheek (~first few weeks) Sucking and swallowing - when object placed in mouth (~3-4 months) Moro reflex - infant reacts to abrupt movements of the head by flinging out arms and crying (disappears ~ 4 months) Babinski reflex - curling of toes when something touches foot Grasping reflex - wrapping fingers around an object Galant reflex - when stroked on the side, baby will roll to that side Swimming reflex - infants move arms and legs in swimming fashion and hold breaths when placed in water (~6 months)

Theta waves are experienced in the drowsy state, essentially Stage 1 of sleep - low frequencies of 4-7Hz, high voltage, irregular waveforms. Delta waves are low frequency (0.5-3Hz), high voltage waves experienced in Stage 3 and 4 of sleep - usually REM sleep or coma.

Depressants and stimulants seem to have opposite effects. Why don't combining stimulants and depressants cancel each other out? (Hint: think mechanistically)

They do not work on the same Neurotransmitters or neurochemical pathways, so effects on both ends of the spectrum are felt.

In the second version of the experiment, the children were shown a man getting punished after he beat up the Bobo Doll. Some children still copied the man, but other children didn't. These children still learned the behavior, though, as evidenced by their ability to imitate the behavior after being bribed with candy. What did this reveal about the *Learning-performance Distinction*?

This experiment revealed that just because you learn something doesn't mean you are going to actually perform what you learned. This is the essence of the *Learning-performance Distinction*.

Jack looks back on the Holocaust, and thinks to himself, "If I were in that situation, I may have done the same thing." Is this an example of the Self-serving Bias?

This is not an example of the Self-serving Bias. Jack would have said, "I would have never done something like that", asserting his actions or morals would be superior.

What happens when you look at a map with directions and street names? Where in the working memory is this dealt with?

This requires *coordination of the Visuo-Spatial Sketchpad and the Phonological Loop* - *a role done by what is called the Central Executive*. It causes them to create an integrated representation stored in the Episodic Buffer (which is a connection to Long term memory)

Describe Piaget's sensorimotor stage

This stage comes where the child is an infant ~0-2 years old - two different types of circular reactions referring to sensorimotor functions: Primary circular rxns are repitition of body movements that occus by chance, e.g. thumb sucking; secondary circular rxns are those when manipulation is focused on something outside the body, like toys. Through this stage the idea of object permanence develops, which is the understanding that objects continue to exist when outside of view

What was Triesmans's Attenuation theory? How does it alter the selective filter idea?

This theory changed the idea of a selective filter to an attenuator, which would weaken but not eliminate other information that is not receiving selective attention. Instead of a complete filter, the attenuator that will not amplify the not-attended information. This focus could then be switched.

What is the expectancy-value theory of motivation?

This theory states that the amount of motivation needed to reach a goal is proportional to both the individuals expectations of success + degree to which they value succeeding at that goal

Broadbent's early selection theory

This theory's idea was that all the information from your environment goes into your sensory register which stores all sensory input you get (e.g. words, sirens, etc.) - then this input gets transferred to the selective filter which identifies what its supposed to be attending to through basic physical cues (voice, pitch, speed, accent etc.) and everything else is filtered out. Perceptual processes assign meaning to the words/noise/etc. Then, cognitive processes can occur.

What is top-down processing?

Top down processing uses your background knowledge to influence your perception e.g. in the following image, there are only circles with lines inside, but we can see a cube in it due to our previous knowledge. Even though there is no cube, we perceive one due to our background knowledge

How do trait theories define personality?

Trait theories of personality use clusters of behavioural patterns to describe individuals - the combination and interaction of various traits defines a personality unique to each individual. No two people by these theories have the same personality.

True or false: representativeness heuristic can lead to base rate fallacy (also called conjunction fallacy)

True. Using representativeness heuristic can lead to using proto/stereotypical factors while ignoring actual numerical information, which is base rate/conjunction fallacy. E.g. Linda is a smart, studious college graduate and works in anti-discrimination volunteer programs. You would assume she's more likely a feminist bank teller over a bank teller, but the numbers show she is more likely to be a bank teller.

True or false: gene regulation states that ~95% of our genes aren't even protein encoding genes, but rather regulators for activation

True: gene regulation states that ~95% of our genes aren't even protein encoding genes, but rather regulators for activation Sort of like "if we experience..(sugar consumption)...then we activate and encode..(insulin)..."

Sensory adaptaton by your sight senses when it's very dark out - what kind of regulation is this?

Up regulation. When it's dark out, pupils dilate, and rods and cones start synthesizing light sensitive molecules.

What would happen if the cribriform plate were completely solid (no holes)?

We would have impaired sense of smell, as the olfactory bulb would be unable to connect to the olfactory epithelium.

What is the purpose of Weber's Law?

Weber noticed that the ratio of the increment threshold to the background intensity is constant. Weber's law quantified the JND for tactile and auditory sensations.

Both nociception and thermoception (pain and temperature sensation, respectively) use TrpV1 receptors. How do these receptors convert cellular damage into neural signals?

When a cell is damaged, it releases chemical signals that diffuse to the nearest TrpV1 receptor and activate it to fire an action potential.

A major problem in recovering from drugs is the dependence that the nervous system can develop for outside sources of dopamine and/or serotonin. What happens in the neural synapses to cause this natural decrease in dopamine/serotonin production?

When the drug is taken initially, the synapses are flooded by excess dopamine/serotonin. With this overstimulation, the brain acts by shutting down some membrane receptors - can lower production of these neurotransmitters and/or the number of channels in the membrane, decreasing sensitivity.

What is selective attention?

When you exercise your attention to focus on only one thing - can be thought of as a flashlight beam on some area of interest in your environment, with things around it being "dimmer"

Describe attention

When you pay attention to something, you focus on it exclusively relative to the environment around

There are no axons that run behind the cones in the fovea, creating an indentation. What is the functional purpose of this lack of axons?

With no nearby axons blocking the light, a higher resolution of light will hit the cones, giving more clarity of vision.

On a very foggy day, a driver can have trouble seeing the traffic light. How could this be an example of Signal Detection Theory?

With thick fog, the driver will guess when the light is green (a decision made with uncertainty).

If a Split Brain patient looks at an object on their right visual field, could they verbally describe the object? Why or why not?

Yes, if a Split Brain patient sees an object in their right visual field, it will be processed on the left side of their brain, where the language center is found. If the object were on the left side, however, the patient could not verbally express the object!

In an autopsy of someone who committed suicide, fewer than normal serotonin and norepinephrine receptors have been found in tissue staining. Is this characteristic of clinical depression?

Yes, studies have shown fewer than average NE and serotonin receptors in patients with depression.

Crystal spent the last calendar year noticeably tense and it was affecting her schoolwork. She often had twitching eyelids and a furrowed brow. Could she have been suffering from General Anxiety disorder (GAD)?

Yes. Since Crystal has had a deficit in her work and her symptoms for over six months from an unclear source, this could be diagnosed as General Anxiety Disorder.

How would your perception change if you only had one eye?

You wouldn't be able to use binocular cues such as convergence or retinal disparity. As a result, you would be less able to accurately perceive depth.
