motivation

a need or desire that energizes and directs behavior

The set of processes that arouse, direct, and maintain human behavior toward attaining some goal

Four perspectives psychologists have used in their attempt to understand motivated behaviors:

instinct theory (now replaced by the evolutionary perspective)

drive reduction theory

arousal theory

hierarchy of needs

instinct theory

focuses on genetically predisposed behaviors

Drive reduction theory

focuses on how our inner pushes and external pulls interact
Arousal theory- focuses on finding the right level of stimulation

hierarchy of needs

describes how some of our needs take priority over others

instinct

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

Many psychologists view human behavior as directed both by:

physiological needs and by psychological wants

drive-reduction theory

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

With few exceptions, when a physiological need increases, so does a

psychological drive

homeostasis

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

The physiological aim of drive reduction is

homeostasis

incentive

a positive or negative environmental stimulus that motivates behavior

Human motivation aims not to eliminate arousal but to seek _____

optimum levels of arousal (curiosity, etc)

Maslow's hierarchy of needs

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

hierarchy of needs

Physiological
Safety
Belongingness and love
Esteem
Self-actualization
Self-transcendence

People in a motivational "hot" state (from fatigue, hunger, or sexual arousal) become more aware of :

having had such feelings in the past and more sympathetic to how fatigue, hunger, or sexual arousal might drive others' behaviors.

glucose

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

Increases in the hormone insulin (secreted by the pancreas) do what?

diminish blood glucose, partly by converting it into stored fat. Your brain automatically monitors your blood chemistry and internal state and will trigger hunger when blood glucose drops.

Signals from your stomach, intestines, and liver (indicating whether glucose is being deposited or withdrawn) all signal your brain

to motivate eating or not

hypothalamus

The small but complex neural traffic intersection deep in the brain

wo distinct hypothalamic centers influence eating:

Activity along the sides of it (the lateral hypothalamus) brings on hunger. If electrically stimulated there, animals begin to eat.
When blood glucose drops, the lateral hypothalamus churns out the hunger-triggering hormone orexin.

Activity in the lower mid-hypothalamus (the ventromedial hypothalamus) depresses hunger.
Problems here lead to obesity and overeating

In addition to producing orexin, the hypothalamus monitors levels of the body's other appetite hormones:

ghrelin
obestatin
PYY
Leptin

ghrelin

a hunger-arousing hormone secreted by an empty stomach (stapled stomachs produce less)

obestatin

a sister hormone to gherkin produced by the same gene that sends out a fullness signal to suppress hunger

PYY

a hormone secreted by the digestive tract

leptin

a protein that is secreted by fat cells and acts to diminish the rewarding pleasures of food

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

basal metabolic rate

the body's resting rate of energy expenditure

When feeling stressed, we crave starchy, carbohydrate-laden food because:

carbs boost the level of serotonin, which has calming effects.

Exposure to one set of novel foods increases ____

our willingness to try another

neophobia

dislike of unfamiliar things

.6%

1%

2.8%

how can family environment provide ground for an eating disorder?

Mothers of girls with eating disorders focus on their own weight and the weight and appearance of their daughters

Families of bulimia patients have a higher-than-usual incidence of childhood obesity and negative self-evaluation

Families of anorexia patients tend to be competitive, high-achieving, and protective

sexual response cycle

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

refractory period

sexual disorder

a problem that consistently impairs sexual arousal or functioning

Sex hormones have two effects:

they direct the physical development of male and female sex characteristics

and (especially in nonhuman animals) they activate sexual behavior.

Estrogens

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

testosterone

the most important of the male sex hormones. Both males and females have it, but 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
