Chapter 8 Motivation and Emotion
2
Motivation
3
The biological, emotional, cognitive, or social forces that activate and direct behavior
4
Instinct Theory
5
The view that certain human behaviors are innate and due to evolutionary programming.
6
Drove Theories
7
The view that behavior is motivated by the desire to reduce internal tension caused by unmet biological needs
8
Homeostasis
9
The idea that the body monitors and maintains internal states, such as body temperature and energy supplies, at relatively constant levels; in general, the tendency to reach or maintain equilibrium
10
Drive
11
A need or internal motivational state that activates behavior to reduce the need and restore homeostasis
12
Incentive theories
13
The view that behavior is motivated by the pull of external goals. Such as rewards
14
Arousal theory
15
The view that people are motivated to maintain an optimal level of arousal that is neither to high nor too low
16
Sensation seeking
17
The degree to which an individual is motivated to experience high levels of sensory and physical arousal associated with varied and novel activities
18
Humanistic Theories of motivation
19
The view that emphasizes the importance of psychological and cognitive factors in motivation, especially the notion that people are motivated to realize their personal potential
20
Glucose
21
Simple sugar that provides energy and is primarily produced by the conversion of carbohydrates and fats; commonly called blood sugar
22
Insulin
23
Hormone produced by the pancreas that regulates blood levels of glucose and signals the hypothalamus, regulating hunger and eating behavior
24
Basal Metabolic Rate
25
When the body is at rest, the rate at which it uses energy for vital functions, such as heartbeat and respiration
26
Adipose tissue
27
Body fat that is the main source of stored, or reserve, energy
28
Energy homeostasis
29
The long-term matching of food intake to energy expenditure
30
Positive incentive value
31
in eating behavior, the anticipated pleasure of consuming a particular food, in general, the expectation of pleasure or satisfaction in performing a particular behavior
32
Satiation
33
In eating behavior, the feeling of fullness and diminished desire to eat that accompanies eating a meal; in general, the sensation of having an appetite or desire fully or excessively satisfied
34
Cholecystokinin (CCK)
35
Hormone secreted primarily by the small intestines that promotes satiation; also found in the brain
36
Sensory-specific satiety
37
the reduced desire to continue consuming a particular food
38
Leptin
39
The hormone produced by fat cells that signals the hypothalamus, regulating hunger and eating behaviors
40
Neuropeptide Y (NPY)
41
Neurotransmitter found in several brain areas, most notably the hypothalamus, that stimulates eating behavior and reduces metabolism, promoting positive energy balance, and weight gain
42
Corticotropin-releasing hormone (CRH)
43
Hormone manufactured promarily in the hypothalamus that reduces eating behavior and increase metabolism, promoting negative energy balance and weight loss
44
Set-point theory
45
Theory that proposes that humans and other animals have a natural, or optimal body weight, called the set-point weight, that the body defends from becoming higher or lower by regulating feelings of hunger and body metabolism
46
Settling-point models of weight regulation
47
General model of weight regulation suggesting that body weight settles, or stabilizes, around the point at which there is balance between the factors influencing energy intake and energy expenditure
48
Body Mass Index
49
A numerical scale indicating adult height in regulation to weight; calculated as: (704.5 x weight in pounds) (height in inches) 2
50
Obese
51
Condition characterized by excessive body fat and a body mass index equal to or greater then 30.0.
52
Cafeteria Diet Effect
53
The tendency to eat more when a wide variety of palatable foods is available
54
Leptin resistance
55
A condition in which higher-than-normal blood levels of the hormone leptin do not produce the expected psychological response
56
Weight cycling
57
Repeated cycles of dieting, weigth loss, and weight regain
58
Eating disorder
59
A category of mental disorders characterized by severe disturbances in eating behavior
60
Anorexia nervosa
61
An eating disorder characterized by excessive weight loss, an irrational fear of gaining weight, and distorted body self-perception
62
Bulimia Nervosa
63
an eating disorder characterized by binges of extreme overeating followed by self induced vomiting, misuse of laxatives or other inappropriate methods to purge the excessive food and prevent weight gain
64
Binge-Eating Disorder
65
A proposed category of eating disorder characterized by recurring episodes of binge eating that are not followed by purging
66
Hierarchy of Needs
67
Maslow’s hierarchical division of motivation into levels that progress from basic physical needs to psychological needs to self- fulfillment needs.
68
Self-actualization
69
Defined by Maslow as a person’s “full use and explication of talents, capacities and potentialities.
70
Self-determination Theory (SDT)
71
Edward Deci and Richard Ryan’s theory that optimal human functioning can occur only if the psychological needs for autonomy, competence, and relatedness are satisfied
72
Intrinsic Motivation
73
Behavior motivated by the desire to engage in tasks that the person fins inherently satisfying and enjoyable, novel, or optimally challenging; the desire to do something for its own sake
74
Extrinsic Motivation
75
Behavior motivated by external factors or influences, such as rewards, consequences, or social expectations
76
Competence Motivation
77
Motivated behavior directed toward demonstrating competence and exercising control in a situation
78
Achievement Motivation
79
Motivated behavior directed toward excelling, succeeding, or outperforming others at a task
80
Thematic Apperception Test
81

82
Emotion
83
A complex psychological state that involves subjective experience, a physiological response, and a behavior or expressive response
