– a need or desire that energizes and directs behavior


a complex behavior that is rigidly patterned throughout a species and is unlearned

Which theory of motivation most clearly emphasizes the importance of genetic predispositions?

Instinct theory

Which theory has been accused of simply naming rather than explaining behaviors?


drive-reduction theory

– the idea that a physiological need creates an aroused tension state (a drive) that motivates an organism to satisfy the need – physiological aim is homeostasis

A need refers to:

a physiological state that triggers motivation arousal

An aroused or activated state that is often triggered by a physiological need is called a(n):


For a thirsty person, drinking water serves to reduce:

a drive

Food deprivation is to ________ as hunger is to ________

need; drive

Victims of a famine will often eat unappetizing and nutritionally poor foods simply to relieve their constant hunger. Their behavior is best explained in terms of:

drive-reduction theory


– a tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level

For a hungry person, the consumption of food serves to:

maintain homeostasis

need; incentive

Which theory would be most helpful for explaining why people are motivated to watch horror movies?

arousal theory

Which theory would be most likely to predict that rats are motivated to explore precisely those areas of an experimental maze where they receive mild electric shocks?

arousal theory

The arousal theory of motivation would be most useful for understanding the aversive effects of:


hierarchy of needs (definition)

– Maslow’s pyramid of human needs, beginning at the base with physiological needs that must first be satisfied before higher-level needs and then psychological needs become active

hierarchy of needs (bottom to top)

– Physiological needs: need to satisfy hunger and thirst – Safety needs: need to feel that the world is predictable – Belongingness and love needs: need to love and be loved – Esteem needs: need for recognition and respect – Self-actualization needs: need to live up to fullest and unique potential – Self-transience needs: need to find meaning beyond the self

The most basic or lowest-level need in Maslow’s hierarchy of human motives includes the need for:

food and water

According to Maslow, our need for ________ must be met before we are preoccupied with satisfying our need for ________

adequate clothing; self-esteem

On the basis of Maslow’s hierarchy of needs, one would be least likely to predict that a:

prisoner might choose to die rather than betray his or her country

hierarchy of needs

Ancel Keys and his colleagues observed that men on a semistarvation diet:

lost interest in sex and social activities

Washburn and Cannon

– Swallowed a balloon to transmit stomach contractions – Discovered that Washburn was indeed having stomach contractions whenever he felt hunger

Research on the physiological basis of hunger has indicated that:

hunger continues in humans whose cancerous stomachs have been removed


– the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger

Increases in the hormone insulin lead to:

decreasing blood glucose levels triggering hunger

In the brain, the hunger controls are located in the ________________


lateral hypothalamus

– brings on hunger – if stimulated there, well-fed animals begin to eat – if the area is destroyed, even starving animals have no interest in food


– hunger-triggering hormone – when given to rats, they become ravenously hungry

ventromedial hypothalamus

– depresses hunger – stimulating this area will cause the animal to stop eating -destroying this area would cause the stomach and intestines to process food more rapidly, causing it to be extremely fat


– hunger-arousing hormone secreted by an empty stomach


– a sister hormone to ghrelin – sends out a fullness signal that suppresses hunger


– a hormone secreted by the digestive tract – appetite-suppressant


– protein secreted by fat cells and acts to diminish the rewarding pleasure of food

Dr. Milosz electrically stimulates the lateral hypothalamus of a well-fed laboratory rat. This procedure is likely to:

cause the rat to begin eating

An animal’s stomach and intestines will process food more rapidly and the animal will become extremely fat if its:

ventromedial hypothalamus is destroyed

Destruction of the ventromedial hypothalamus of a rat is most likely to:

cause the rat to become extremely fat

Leptin, a hunger-dampening protein, is secreted by:

fat cells

set point

– the point at which an individual’s "weight thermostat" is supposedly set – when the body falls below this weight, an increase in hunger and a lowered metabolic rate may act to restore the lost weight

An explanation of motivation in terms of homeostasis is best illustrated by the concept of:

set point

basal metabolic rate

– the body’s resting rate of energy expenditure

Our weight thermostats are somewhat flexible and are influenced by environmental as well as biological factors. Some researchers have therefore adopted the term:

settling point

anorexia nervosa

– an eating disorder in which a person (usually an adolescent female) diets and becomes significantly (15 percent or more) underweight, yet, still feeling fat, continues to starve

bulimia nervosa

– an eating disorder characterized by episodes of overeating, usually of high-calorie foods, followed by vomiting, laxative use, fasting, or excessive exercise

binge-eating disorder

– significant binge-eating episodes, followed by distress, disgust, or guilt, but without the compensatory purging, fasting, or excessive exercise that marks bulimia nervosa

less sincere and less friendly

Research on obesity and weight control indicates that:

no matter how carefully people diet, they can never lose fat cells

Although John has been obese for as long as he can remember, he is determined to lose excess weight with a special low-calorie diet. John is likely to have difficulty losing weight while dieting because:

fat tissue can be maintained by fewer calories than can other body tissues

TV viewing habits

Having lost weight, formerly obese individuals have ________ fat cells and ________ metabolic rates

smaller; slower

sexual response cycle

– the four stages of sexual responding described by Masters and Johnson—excitement, plateau, orgasm, and resolution

plateau phase

– excitement peaks as breathing, pulse, and blood rates continue to increase


– muscle contractions – further increases in breathing, pulse, and blood pressure rates

refractory period

– a resting period after orgasm, during which a man cannot achieve another orgasm


– sex hormones, such as estradiol, secreted in greater amounts by females than by males and contributing to female sex characteristics – in nonhuman female mammals, estrogen levels peak during ovulation, promoting sexual receptivity


– the most important of the male sex hormones – both males and females have it, but the additional testosterone in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty

During the resolution phase of the sexual response cycle, people are most likely to experience a rapid decrease in physiological arousal if:

they have just experienced an orgasm

autonomic nervous system

– mobilizes your body for action and calms it when the crisis

The two factor theory of emotion places more emphasis on the importance of ________ than do other theories of emotion

cognitive activity

The autonomic nervous system regulates the ________ that accompanies different emotions

physiological arousal

sympathetic division of ANS

– directs adrenal glands to release the stress hormones epinephrine (adrenaline) and norepinephrine (noradrenaline)

parasympathetic division of ANS

– neural centers inhibit further release of stress hormones and arousal diminishes gradually

A hormone that increases heart rate, blood pressure, and blood sugar levels in times of emergency is



– a machine, commonly used in attempts to detect lies, that measures several of the physiological responses accompanying emotion (such as perspiration and cardiovascular and breathing changes)

spillover effect

– when our arousal response to one event spills over into our response to the next event

The suggestion that "a happy face creates a merry soul" is most consistent with the

James-Lange theory

facial feedback

– the effect of facial expressions on experienced emotions, as when a facial expression of anger or happiness intensifies feelings of anger or happiness

Repeatedly saying the word "me" puts people in a better mood than repeatedly saying "you." This best illustrates the

facial feedback effect

People experience a mood shift when they switch from taking short shuffling steps to taking long strides and swinging their arms by their sides. This best illustrates

the behavior feedback pehnomenon

After 9/11, Americans who responded with anger more than fear also displayed

more intolerance for immigrants

"I’m really angry that I had to wait so long for you to get here."

Rosaria is upset with her husband for not putting his dirty clothes in the laundry basket. Anger experts would most likely recommend that she deal with her frustration by saying to him

"It annoys me that you leave your dirty clothes for me to pick up."
