Q

What is the role of the ventromedial hypothalamus (lower mid-hypothalamus)? What happens if it is destroyed?

A

It depresses hunger. Stimulate this area and an animal will stop eating; destroy it and the animals stomach and intestines will process food more rapidly, causing it to become extremely fat.

Q

Set point

A

The point at which an individuals “weight thermostat” is supposedly set.

21
Q

What happens when the body falls below the set point?

A

An increase in hunger and a lowered metabolic rate may act to restore the lost weight

22
Q

What is basal metabolic rate?

A

The body’s resting rate of energy expenditure

23
Q

Neophobia

A

A dislike of things unfamiliar to you

24
Q

Social facilitation

A

The presence of others tends to amplify our natural behavior tendencies (Ex. We may realize after a party that we have overeaten)

25
Unit bias
When people are served larger portions of food they eat more
26
Anorexia nervosa
An ED in which a person (usually an adolescent female) diets and becomes significantly (15% or more) underweight, yet, still feeling fat, continues to starve
27
Bulimia nervosa
An ED characterized by episodes of overeating, usually of high-calorie foods, followed by vomiting, laxative use, fasting, or excessive exercise
28
Binge-eating disorder
Significant binge-eating episodes, followed by distress, disgust, or guilt, but without the compensatory fasting, etc
29
What is the role of fat cells in obesity?
In an obese person, fat cells may swell to two or three times their normal size and then divide or trigger nearby, immature, fat cells to divide - resulting in more fat cells. Once the number of fat cells increases it never decreases, but their fat cells could shrink.
30
How does sleep loss affect weight gain?
With sleep deprivation, the levels of leptin (which reports body fat to the brain) fall and ghrelin (the stomach hormone that stimulates appetite) rise, therefore you’re more vulnerable to obesity
31
How does social influence affect weight gain?
People are more likely to become obese when a friend becomes obese
32
How does changing food consumption and activity levels affect weight gain?
The availability of unhealthy foods, and how normal they are in your society can cause you to gain weight
33
Sexual response cycle
The four stages of sexual responding described by Masters and Johnson - excitement, plateau, orgasm, and resolution.
34
Refractory period
A testing period after orgasm, during which a man cannot achieve orgasm
35
Estrogen
A sec hormone secreted in greater amounts of females than by males and contributing to female sex characteristics
36
Testosterone
The most important of the male sex hormones: stimulates the growth of male sex organs in the fetus and the development of the male sex characteristics during puberty
37
Sexual orientation
An enduring sexual attraction toward members of either one’s own sex or the other sex
38
Competence motivation
Show by people who are driven to master a task or achieve a personal goal
39
Achievement motivation
Occurs when people try to outdo, or beat, other people
40
Self-efficacy belief
Level of confidence one has when facing the challenges and demands of a situation
41
Arousal theory
Motivation aims not to eliminate arousal but to seek optimum levels of arousal
42
Maslow’s hierarchy of 6 needs (from least important to most)
1. Self- transcendence (need to find meaning) 2. Self-actualization (need to live up to our potential) 3. Esteem needs 4. Belongingness and love 5. Safety 6. Physiological (need to satisfy hunger or thirst)
43
What was Ancel Keys experiment?
- fed 36 volunteers just enough to maintain initial weight, then cut rations in half - they lost interest in any activities not involving food - conclusion: food and hunger have a powerful effect on us
44
What was Washburn’s experiment?
- swallowed a balloon, which measured stomach contractions - he would press a button each time he felt hungry - conclusion: our stomachs contracts when we feel hungry
45
Ostracism
Social exclusion - leads to depression
46
Cyber-ostracism
Ignored friend request on Facebook, unanswered email, checked kakao message but no reply
47
Anterior Cingulate Cortex
Brain area activated in response to physical pain and social pain
48
What biological factors influence hunger?
- hypothalamic centers in the brain monitoring appetite - appetite hormones - stomach pangs - weight set/settling point - attraction to sweet and salty tastes - adaptive wariness toward novel foods
49
What 2 social factors influence hunger?
- culturally learned taste preferences - responses to cultural preferences for appearance
