lesson 6
By comparing twins raised apart to twins raised together, one can estimate how much of a trait is attributable to genetics and how much to environment. This study reported that 56 percent of the variability in whether or not people develop anorexia nervosa is attributable to (1)_____ influence, with most of the remaining influence (38 percent) being attributable to the common (2)_______.
1. genetics 2. environment shared with family members
the two factors of incentive value
1. success at the task has to be important to you. 2. the more difficult the task and the lower the odds of succeeding at it, the more it will mean to you if you do succeed.
at what month can discriminate between different types of facial expressions of emotion
5 months note: and by one year of age they rely on the faces of their caregivers to convey important information about how they might act
genes is responsible for about ____ percent of adult weight gain
70%
brain effects in real orgasm vs fake orgasm
Achieving a real orgasm always involved deactivation of brain regions involved with fear and anxiety in the amygdala and hippocampus as well as parts of the cortex involved in consciousness. During faked orgasms, however, these brain regions remained activated. Men too show brain deactivation during orgasm, but only in the left amygdala
How is BMI measured?
BMI is determined by dividing weight by height to yield a weight-to-height ratio
theory that incoming emotional sensory stimuli travel to the thalamus, where the signal gets divided into a descending pathway to control body arousal and an ascending cortical pathway to control emotional experience.
Cannon-Bard theory of emotion
a smile that expresses true enjoyment, involving both the muscles that pull up the lip corners diagonally and those that contract the band of muscles encircling the eye.
Duchenne smile
This theory looks at internal drives to explain why people do what they do.
Evolutionary theory
a widely used method for measuring all observable muscular movements that are possible in the human face.
Facial Action Coding System (FACS)
hormone secreted by empty stomach; sends "I'm hungry" signals to the brain
Ghrelin
Doug Kenrick and colleagues bridged the evolutionary and hierarchical models of motivation by modifying Maslow's hierarchy from an evolutionary perspective. The new model builds on basic needs. List them (from base to tip)
Immediate physiological needs. Self-protection. Affiliation. Status/esteem. Mate acquisition. Mate retention. Parenting.
the perception of the physiological changes that accompany emotions that produces the subjective emotional experience.
James-Lange theory of emotion for example, because we perceive different body changes for each emotion. In short, "I am trembling, and therefore I am afraid; or I feel a lump in my throat, therefore I am sad."
______ is released in the hypothalamus when an animal is hungry or underfed, and it stimulates appetite
Neuropeptide Y (NPY)
the concept that individuals have an internal motivation to maintain the right amount of arousal
Optimal Arousal Model
This view of emotions illustrates the adaptive value of negative emotions, which enable people to respond efficiently to a significant challenge or obstacle. For example, when danger approaches, the heart pumps blood to the skeletal muscles to enable quick movement in case escape is necessary, the respiratory system works harder to bring in more oxygen, and the brain prioritizes attention so that we can figure out what we need to do to escape the dangerous situation
Organized responses
program that gives teachers a detailed curriculum for improving children's emotional awareness and regulation skills and enhancing their social competence.
PATHS program (Providing Alternative THinking Strategies)
hierarchical model levels from base to tip note! According to this model, lower-level needs must be satisfied before we can focus on achieving self-actualization.
Physiological needs. Safety and security needs. Love and belongingness needs. Esteem needs. Self-actualization.
the principle that moderate levels of arousal lead to optimal performance.
Yerkes-Dodson law
Stress-induced negative mood enhances preference for sweet foods, since they contain carbohydrates that boost brain levels of a. serotonin. b. insulin. c. orexin. d. neuropeptide Y.
a. serotonin.
Brain imaging research has found that during orgasm a. some parts of the brain "shut down" and become deactivated. b. most of the brain becomes very active. c. only the brain stem is active. d. the insula becomes very active.
a. some parts of the brain "shut down" and become deactivated.
a desire to do things well and overcome obstacles.
achievement motivation
stable predispositions toward certain types of emotional responses such as anger. Consider the example of being cut off in traffic. People who have the affective trait of hostility are most likely to feel anger. They aren't always angry, but they have hair triggers.
affective traits
the need to build relationships and to feel part of a group
affiliation need
this part of the brain play a very important role in appraisal of the emotional significance of stimuli, with a specialized function for noticing fear-relevant information
amygdala
4 parts of the brain that play key roles in the way we experience emotion and remember emotional experiences
amygdala, prefrontal cortex, anterior cingulate cortex, and the hypothalamus
an eating disorder in which people cannot maintain 85 percent of their ideal body weight for their height, have an intense fear of eating, and have a distorted body image.
anorexia nervosa
a situation that may lead to an emotional response.
antecedent event
the evaluation of a situation with respect to how relevant it is to one's own welfare; it drives the process by which emotions are elicited.
appraisal for example, the level of happiness expressed by Olympic athletes can be greater for winners of the bronze medals (third place) than for winners of the silver medal (second place). Bronze medalists could easily imagine an alternative outcome: They may not have even placed. Compared to that outcome, third is great. Silver medalists, on the other hand, could easily imagine and hope for an alternative outcome: Winning first place! Compared to that outcome, second is somewhat disappointing. Our own beliefs clearly influence the way in which we appraise our situation, as do our personalities, personal histories, and goals.
polygraph reliability in correctly detecting lying ranges from 70 to 85 percent, there is an alarming proportion of incorrectly identified lies, somewhere in the range of 7 to 15 percent. This means that 7 to 15 percent of the time, an honest person is incorrectly identified as a liar. This might be due to the fact that the polygraph actually measures ________, and therefore will detect general anxiety associated with being questioned as well as tension associated with the deception itself
arousal
The physiological system responsible for changes during an emotional response is the what? ex. The heart pumps blood rapidly to the muscles; oxygen intake in the lungs increases; and processes that are not immediately necessary for action, such as digestion, shut down so that energy is conserved for more urgent body functions
autonomic nervous system (ANS)
Most research on weight loss has reported that a. losing weight is very difficult for most people. b. losing weight is relatively easy, but keeping it off is very difficult. c. keeping weight off is relatively easy for most people. d. losing weight is relatively easy and so too is keeping it off.
b. losing weight is relatively easy, but keeping it off is very difficult.

between 20 and 25
Fredrickson's model for positive emotions, which posits that they widen our cognitive perspective and help us acquire useful life skills. Play, for example, especially the rough-and-tumble play of animals and young children, helps develop physical and strategic skills that may be useful for hunting, escaping, or defensive fighting.

d. appraisal
In humans, lesions to parts of the hypothalamus lead to a ______ (increase or decrease) in sexual behaviour
decrease
learned norms or rules, often taught very early, about when it is appropriate to express certain emotions and to whom one should show them.
display rules
the idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need
drive-reduction model
the perceived states of tension that occur when our bodies are deficient in some need, creating an urge to relieve the tension.
drives
the cognitive and behavioural efforts people make to modify their emotions.
emotion regulation
the physiological, behavioural/expressive, and subjective changes that occur when emotions are generated.
emotional response
brief, acute changes in conscious experience and physiology that occur in response to a personally meaningful situation.
emotions
The________ are naturally occurring neurochemicals that can increase appetite. Blocking receptor sites for this leads to a decrease in eating and to weight loss
endocannabinoids
In general, drives come from the body, whereas incentives come from the ________.
evironment
what are the four phases of sexual arousal?
excitement, plateau, orgasm, and resolution
a response-focused strategy for regulating emotion that involves the deliberate attempt to inhibit the outward manifestation of an emotion. For instance, in order to avoid a confrontation, you might literally bite your lip rather than tell your roommates that they are slobs for letting the dishes pile up and waiting for you to wash them.
expressive-suppression
a simple sugar that provides energy for cells throughout the body, including the brain.
glucose
Another model of motivation, which combines drives and incentives. Needs range from the most basic physiological necessities to the highest, most psychological needs for growth and fulfillment
hierarchical model (pyramid) by Maslow
the process by which all organisms work to maintain physiological equilibrium or balance around an optimal set point.
homeostasis
Our blood sugar level drops when we go without eating for long periods. If this happens, the ________ (part of the brain), which monitors glucose levels, triggers the drive to obtain food. It acts as hunger's sensory detector.
hypothalamus
any external object or event that motivates behaviour.
incentive For some people, money is a primary incentive, but for others winning a gold medal at the Olympics or getting a university degree might be the main incentive behind their training or studying.
an inherited behavioural tendency that has been preserved within a species because it helped ensure survival.
instinct
brain structure most involved in interoception, or the perception of sensations arising within the body. As such, it plays an important role in emotional experience.
insula
At least four hormones suppress appetite. what are they?
insulin, leptin, peptide YY (PYY), and cholecystokinin
region of the hypothalamus that promotes feeding.
lateral hypothalamus note Lesioning of this area has also been performed in humans as a controversial treatment for obesity. Subsequent destruction of this area reduced caloric intake and body weight in these patients. Although these results were promising, results were temporary, suggesting that other areas are also likely involved in hunger
the overall evaluation we make of our lives and an aspect of subjective well-being
life satisfaction
The rate at which we consume energy
metabolism
affective states that operate in the background of consciousness and tend to last longer than most emotions.
moods
the urge to move toward one's goals; to accomplish tasks.
motivation
inherently biological states of deficiency (cellular or bodily) that compel drives.
needs
Ekman's explanation that some aspects of emotion, such as facial expressions and physiological changes associated with emotion, are universal and others, such as emotional regulation, are culturally derived.

what is the BMI range that is considered overweight? Obese?
overweight - 26-29.9 obese - 30 or above
Female-initiated sexual behaviour peaks around what course of the 28-day menstrual cycle?
ovulation and again before and after menstruation
the division of the autonomic nervous system that calms the body, conserving its energy
parasympathetic nervous system
societies that place few restrictions on sex
permissive societies
one of the more active regions of the brain in the experience and appraisal of emotions. Damage to the left prefrontal cortex results in depression. clinically depressed people show less activity in the left prefrontal cortex than do non-depressed people
prefrontal cortex
an emotion-regulation strategy in which one re-evaluates an antecedent event so that a different emotion results. For example, rather than seeing your next midterm as an opportunity for failure, an outlook that might create fear or anxiety, you might reappraise the exam as a challenging opportunity to prove to yourself and others how much you have learned, an outlook that would lead to eager anticipation.
reappraisal
society that restrict sex before and outside of marriage
restrictive societies
The most reliable behavioural changes associated with deception are...?
rigid posture reduction of hand and arm movements long pauses in speech lower rates of blinking
the inherent drive to realize one's full potential.
self-actualization
types of emotion that require a sense of self and the ability to reflect on actions; they occur as a function of meeting expectations (or not) and abiding (or not) by society's rules. ex. The feeling of pride a child feels at learning how to ride a bike and the shame of being caught in a lie
self-conscious emotions
societies that prohibit premarital sex, but do not strictly enforce this prohibition
semirestrictive societies
- this tells the brain when the set point has been achieved, and the brain then tells the body to stop correcting. - Signals that are produced by a response and are often used to guide the continuation of the response
sensory feedback
the ideal fixed setting of a particular physiological system, such as internal body temperature.
set point

the stomach, the blood, the brain, and hormones and neurochemicals.
term referring to something that is common to all human beings and can be seen in cultures all over the world.
universal
region of the hypothalamus that promotes satiety (feeling full). Destruction of this area leads to overfeeding and weight gain, while stimulation has the opposite effect
ventromedial hypothalamus
the ______ exerts a long-term effect on our sexual orientation
womb Research has revealed that, to some extent, individuals exposed to relatively high levels of testosterone in the womb are more likely to be attracted to women, whereas those exposed to relatively low levels of testosterone are more likely to be attracted to men
