John Garcia

●Challenged idea that any natural response can be conditioned to any NS and tested this theory using classical conditioning ●Rats love sweetwater, and they began to avoid it after it was poisoned. Sickened rats experienced taste aversion ●US: poison, UR: sickness, CS: sweetwater, CR: sickness Other Findings: ●Even if sickened as late as several hours after tasting a particular flavor, the rats thereafter avoided that flavor. This appeared to violate the notion that for conditioning to occur, the US must immediately follow the CS. ●The sickened rats developed aversions to tastes but not to sights or sounds.

Smell/Olfaction

●Chemical sense: molecules sent to receptor cells (embedded on surface of nasal cavity neurons) in the nasal cavity (respond selectively)--> olfactory nerve--> olfactory bulb--> thalamus--> smell cortex in temporal lobe--> limbic system (memory, emotion) ●No distinct receptor for each detectable odor (combination) ●Attractiveness of smell depends on learned associations (memory). ●Only sense not routed in thalamus

Death and Dying

●Difficult separation from spouse ●When death is natural, grieving = short-lived ●When death is sudden, grieving = severe ●Reactions differ with culture (not predictable stages) ●Strong expressions of emotion may not purge grief, and bereavement therapy is not significantly more effective than grieving without such aid. ●Integrity: One's life has been meaningful (vs. despair)

Neurotransmitter

●When an action potential reaches terminals, it triggers the release of these (chemical messengers that cross synaptic clefts between neurons. When released by the sending neuron, they travel across synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse). ●Ions flow in--> excite or inhibit an action potential. ●Produced inside the body

Therapy conducted with groups rather than individuals, permitting therapeutic benefits from group interaction, like learning that others have similar problems.

behavior therapy

Therapy that applies learning principles to the elimination of unwanted behaviors. Focus on what we do.

cognitive therapy

Therapy that teaches people new, more adaptive ways of thinking; based on the assumption that thoughts intervene between events and our emotional reactions. Focus on what we think. Can get quick results.

family therapy

Therapy that treats the family as a system. Views an individual's unwanted behaviors as influenced by, or directed at, other family members.

Roger Sperry and Michael Gazzaniga

These two scientists divided brains of cats and monkeys at the corpus callosum. Also did split brain visual studies on the human brain. Said there are "two separate minds". Roger Sperry: Mind and brain are a holistic system. The brain creates and controls the emergent mind, which in turn influences the brain.

Critical Thinking

Thinking that does not blindly accept arguments and conclusions. Rather, it examines assumptions, assesses the source, discerns hidden values, evaluates evidence, and assesses conclusions. It is informed by science and helps clear the colored lenses of our biases. It recognizes multiple perspectives. Actively processing information, analyzing, asking ?

empathy-altruism theory

This is based on one's feelings for others. If someone feels empathy for someone, they will help them even if they have nothing to gain from it. If there is no empathy, the social exchange theory takes control.

Law of Effect

Thorndike's principle that behaviors followed by favorable consequences are more likely, and that behaviors followed by unfavorable consequences become less likely (behavior control) / no internal cognition

How Effective is Psychotherapy?

Those not undergoing therapy often improve, but those undergoing therapy are more likely to improve more quickly, and with less risk of relapse.

cognitive psychology

To explore scientifically the ways we perceive, process, and remember information. Someone working from the cognitive perspective might study how our interpretation of a situation affects our anger and how our anger affects our thinking.

Sublimation

Transferring of unacceptable impulses into socially valued motives.

Cochlear Nerve

Transfers auditory information from cochlea to brain.

Adolescence

Transition period from childhood to adulthood, extending from puberty to independence (time of validity).

Auditory Canal

Transmits sound waves from pinna to tympanic membrane.

Lens

Transparent structure behind the pupil that changes shape to help focus images on the retina.

Hypnotherapists

Try to help patients harness their own healing powers / change their problems

Amygdala

Two lima-bean-sized neural clusters that are linked to strong emotions. (aggression, fear)

Transgender

Umbrella term describing people whose gender identity or expression differs from that associated with their birth sex. (gender expression; transsexual)

Repression

Underlies all other defense mechanisms. The basic mechanism that banishes anxiety-arousing impulses and enables other defense mechanisms.

Latent Content

Underlying meaning of a dream / unconscious drives / wishes

discrimination

Unjustifiable negative behavior toward a group and its members-- motivated by prejudice.

altruism

Unselfish regard for the welfare of others without regard to your own self-interest. Picture: Other factors, including our mood and similarity to the victim, also affect our willingness to help.

industrial-organizational (I/O) psychology

Use psychology's concepts and methods in the workplace to help organizations and companies select and train employees, boost morale and productivity, design products, and implement systems.

applied research

Use the knowledge developed by experimental psychologists to solve human/practical problems.

Sexual Orientation

●Enduring sexual attraction toward members of either one's own sex (homo), the other sex (hetero), or both sexes (bi). -Neither willfully chosen nor willfully changed. -Not an indicator of mental health -Men= less erotic plasticity (sexual variability) than women -Environment doesn't affect S.O. ●Proof of Biology/Difference in Sexual Orientation -Same-sex attraction in other species -Gay-straight brain differences *Hypothalamus cell cluster= reliably larger in hetero men than in women and homo men. (different development soon after birth) -Genetic Influences *Family studies--> evolutionary / maternal genetics *Twin studies--> same orientation *Fruit fly studies--> multiple genes *Prenatal influences--> exposure to hormone levels or mother's immune system (fraternal birth-order effect) -Gay-Straight Trait Differences (Table 53.1) *Traits fall midway between straight males and females

The Competent Newborn

●Equipped with automatic reflex responses (cries for nourishment) ●Habituation

Basic Trust

●Erik Erikson ●Sense that the world is predictable and trustworthy; said to be formed during infancy by appropriate experiences with responsive caregivers ●Formed with good, early parenting

Weber's Law

●Ernst Weber ●Principle that, to be perceived as different, 2 stimuli must differ by a constant minimum percent (rather than a constant amount)

Opponent Processing Theory

●Ewald Hering / Afterimages ●Opposing retinal processes (red-green, yellow-blue, white-black) enable color vision.

*Norepinephrine (NE)

●Excitatory ●Used for arousal in the flight/fight response (alertness), modulation of mood, plays a role in learning and memory retrieval ●Effect of Deficit: Depression + other mental disorders ●Effect of Surplus: Anxiety

Glutamate

●Excitatory ●Works together with GABA ●Used in memory, learning, movement. Helps messages cross the synapse more efficiently ●Effect of Deficit: None ●Effect of Surplus: Too much glutamate (and too little GABA) is associated with epileptic seizures

Acetylcholine

divergent thinking

●Expands the number of possible problem solutions (diverges in different directions) ●Creativity tests ●Injury to certain areas of the frontal lobes damages this ability

B.F. Skinner

●Experiment w/ operant chamber about reinforcement ●Behaviorism ●Legacy: Critics said his work was dehumanized / His reply- actions are controlled by external consequences, reinforcement=humane

George Sperling

●Experiment where people viewed 3 rows of 3 letters each, for only 1/20 of a sec. After the 9 letters disappeared, they could recall about 1/2 of them. -When signaled to recall a particular row immediately after the letters had disappeared and after a tone was rung, they could do so with accuracy. ●Iconic Memory

Cerebellum

●Extends from the rear of the brainstem (called little brain) ●Balance, coordination, and motor memory

basal ganglia

●Facilitate formation of our procedural memories for skills (implicit memories) ●Receive input from the cortex but do not send information back to it for conscious awareness of procedural learning

attitude

●Feelings, often influenced by our beliefs, that predispose us to respond in a particular way to objects, people, and events. ●___________ affect actions + actions affect __________.

Zygote

●Fewer than half survive beyond the 1st 2 weeks ●The fertilized egg; it enters a 2-week period of rapid cell division and development into an embryo. ●Conception--> 2 weeks

James Flynn

●Flynn Effect (college entrance aptitude scores were dropping in the 60's-70's but intelligence test scores were improving.) ●Rising performance in intelligence tests ●Standardization

functional fixedness

●Form of mental set ●The inability to perceive a new use for an object- limits a person to seeing an object only used the way it is supposed to.

Theory of Mind

●Forming in preschool ●People's ideas about their own and others' mental states - about their feelings, perceptions, and thoughts, and the behaviors these might predict. ●Others' thoughts can be different

Roy Baumeister

●Found that people tend to see their foibles and attitudes in others, which is called the false consensus effect: the tendency to overestimate the extent to which others share our beliefs and behaviors. ●Experimented with the "dark side of high self-esteem."

Dream Theories / Table 24.3

●Freud's wish-fulfillment: Satisfy our own wishes & unacceptable feelings; dreams=key to understanding inner conflicts; manifest and latent content / discredited: lacks scientific support + dreams can be interpreted ●Information Processing: Sort out day's events and file away memories; REM sleep = important to memories / but why do we sometimes dream about things we haven't experienced? ●Physiological Function: Develop and preserve neural pathways from regular brain stimulation in REM sleep / but why do we experience meaningful dreams? ●Neural Activation: REM sleep triggers neural activity that evokes random visual memories, which our sleeping brain weaves into stories / but the individual's brain is weaving the stories ●Cognitive Development: Dream content reflects dreamers' cognitive development; top-down / but it doesn't address the neuroscience of dreams

Unconscious

●Freud: Reservoir of mostly unacceptable thoughts, wishes, feelings, and memories. ●Modern: Info processing of which we are unaware.

Formal Operational Stage

●From 12--> adulthood ●Abstract thinking, systematic reasoning ●Apply new abstract reasoning tools to world around us

Preoperational Stage

●From 2--> 6,7 years ●Where a child learns to use language but doesn't comprehend mental operations of concrete logic. ●Conservation, symbolic thinking, egocentrism, theory of mind

Lawrence Kohlberg (Table 51.1)

●Moral reasoning guides moral actions (unconscious) ●Moral reasoning (thinking that occurs as we consider right and wrong) ●Moral Intuition (quick gut feelings or affectively laden intuitions) -Human morality is run by moral emotions / moral reasoning is pretending to be in control -Moral intuitions trump moral reasoning ●Moral Action (thinking, feeling, and doing the right thing; moral action feeds moral attitudes) ●Moral decisions are egocentric ●Changes in the stages: fueled by changes in cognitive capability STAGE THEORY ON MORAL DEVELOPMENT ●Preconventional Morality: Birth--> 9yrs; self-interest (obey rules to avoid punishment or gain concrete rewards) -1) Avoid punishment -2) Gain Reward ●Conventional Morality: 9--> 20yrs; uphold laws to gain social approval or maintain social order. -3) Gain Approval & Avoid Disapproval -4) Duty & Guilt ●Postconventional Morality: 20+ or maybe never; actions reflect belief in basic rights + self-defined ethical principles -5) Agreed upon rights -6) Personal moral standards

Testosterone

●Most important of the male sex hormones. Both males and females have it, but the additional testosterone in males stimulates growth of male sex organs in fetus + development of male sex characteristics during puberty. ●4th-5th prenatal months: Sex hormones bathe fetal brain and influence its wiring (causes sexual differentiation)

Pituitary Gland

●Most influential gland / master gland ●Controls hypothalamus: regulates growth and influences hormone secretion by other endocrine glands. -Examples: Growth Hormone, Oxytocin

Sigmund Freud

●Mostly case studies ●Unconscious ●Psychoanalysis ●Layers of Mind: Conscious, Preconscious, Unconscious ●Parts of Personality: Id, Ego, Superego ●Psychosexual Stages ●Defense Mechanisms ●Repression

Motor Cortex

●Motor function ●An area at the rear of the frontal lobes that controls voluntary movements (issues orders to move body). Stimulating parts in the left or right hem. cause movements on the opposite side of the body. ●Body areas requiring precise control occupy the greatest amount of cortical space.

convergent thinking

●Narrows the available problem solutions to determine the single best solution ●Intelligence tests ●Injury to the left parietal lobe damages this ability

Maturation

●Nature ●Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience. (experience [nurture] adjusts it)

Behavior Genetics

●Nature and nurture shape development ●Study of our differences and weighing the effects + interplay of heredity and environment

Karen Horney

●Neo-Freudian ●Childhood is important but social, not sexual, tensions are crucial for personality formation. Childhood anxiety triggers our desire for love and security, fought for women's self-respect. ●Womb envy ●Self Help

Alfred Adler

●Neo-Freudian ●Childhood is important but social, not sexual, tensions are crucial for personality formation. Inferiority complex + conquer childhood inferiority ●Birth order is important in developing personality.

Carl Jung

●Neo-Freudian ●Freud's disciple-turned-dissenter -- placed less emphasis on social factors; unconscious exerts powerful influences; unconscious contains more than our repressed thoughts and feelings; unconscious is the source of creative impulse ●Collective unconscious (collection of memories from our history- archetypes)

The Eye

●Nerves transfer the signal to the brain. ●Light enters the eyes through the pupil--> lens --> retina--> rods and cones in retina--> bipolar cells--> optic nerve Light rays reflected from a candle pass through the cornea, pupil, and lens. The curvature and thickness of the lens change to bring nearby or distant objects into focus on the retina. Rays from the top of the candle strike the bottom of the retina, and those from the left side of the candle strike the right side of the retina. The candle's image on the retina thus appears upside down and reversed, but perceived upright in the brain.

Action Potential

●Neurons transmit messages when stimulated by signals. In response, neurons fire an impulse, called this. ●Neural impulse; a brief electrical charge that travels down an axon. ●Neurons generate electricity from chemical events. ●Ions= chemically charged atoms that are exchanged (axon's surface is selectively permeable) ●Direction of Electrical Impulse: Only one direction, away from cell body through axon to terminal

NREM sleep

●Nonrapid eye movement sleep; encompasses all sleep stages except for REM (1 hour of this, then REM) ●No paralysis or dreams ●Order: NREM-1, NREM-3, NREM-2, REM

Hypnosis as a Social Phenomenon (Role Theory)

●Normal consciousness ●Social influence theory of hypnosis~ role playing "good subject"

Daniel Kahneman

●Notable for his work on the psychology of judgment and decision-making, as well as behavioral economics. ●Challenged the assumption of human rationality prevailing in modern economic theory. ●With Tversky and others, established a cognitive basis for common human errors that arise from heuristics and biases and developed prospect theory

Stanley Milgram (Figure 75.2)

●Obedience ●If the "learner" gives a wrong answer on a list of word pairs, the "teacher" delivers a mild shock. With each succeeding error, you move to a higher voltage. After many wrong answers you hear the learner begin to scream but the experimenter says you must continue. The majority complied. -No real shock was being delivered to the learner/confederate ●Most people were sure they would stop in a survey taken before the experiment. -All cruelty takes is ordinary people corrupted by an evil situation.

Today's Views on Piaget's Theory

●Object permanence unfolds gradually ●There are sequences of cognitive milestones, but development is seen as more continuous ●Piaget underestimated children's competence

Color Vision

●Objects reflect wavelengths of color. Color is our mental construction (it doesn't exist outside the brain, perception). ●Color processing occurs in 2 stages--> YHTT, then processed by nervous system's opponent-process cells (OPT)
