a need or desire that energizes and directs behavior.
instinct theory
theory whose underlying assumption is that genes predispose species-typical behavior; names instead of explains behavior and fails to explain most human motives.
evolutionary perspective
perspective that serves as the modern day form of instinct theory.
drive-reduction theory
theory that physiological need creates an aroused tension state (aka “drive”) that motivates an organism to satisfy said need.
an aroused tension state.
a complex behavior that is rigidly patterned throughout a species and is unlearned.
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; what motivates drive-reduction theory.
a positive or negative environmental stimulus that motivates behavior.
human motivation
aims not to eliminate arousal but seeks optimum levels of arousal.
too much stimulation, want to decrease arousal.
too little stimulation, want to increase arousal.
hierarchy of needs
Maslow’s pyramid; physiological needs must first be satisfied before higher-level safety needs and then psychological needs become active.
self-transcendence level
people strive for meaning, purpose, and communion that is beyond the self, that is transpersonal.
modern pyramid add-ons
gaining and retaining mates, and parenting offspring.
Keys’ experiment
the semi-starved men’s preoccupations w/food and hunger illustrated how activated motives can hijack our consciousness: when you are hungry, food matters; subjects lowered BMR to adjust to lowered ability to consume food.
Washburn experiment
showed that stomach contractions (transmitted by the stomach balloon) accompany our feelings of hunger (indicated by a key press).
can persist w/o stomach pangs or even stomach!
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.
appetite hormone secreted by the pancreas that controls blood glucose; actually diminishes blood glucose, partly by converting it to stored fat.
arcuate nucleus
neural arc of hypothalamus that has two centers, one that secretes appetite-stimulating hormones and another that secretes appetite-suppressing hormones.
a hunger-arousing hormone secreted by an empty stomach and sends “I’m hungry” signals to the brain.
appetite hormone secreted by fat cells that decreases hunger.
appetite hormone secreted by the hypothalamus that increases hunger.
appetite hormone secreted by the digestive tract that decreases hunger.
set point
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; heredity influences.
basal metabolic rate (BMR)
the body’s resting rate of energy expenditure.
settling point
indicates the level at which a person’s weight settles in response to caloric intake and expenditure (which are influenced by environment as well as biology) – alternative to biologically fixed “set point”.
Rozin experiment

sweet and salty
preferences for these tastes are genetic and universal.
dislike of things unfamiliar; an adaptive trait.
repeated sampling
doing this will repeatedly typically increase appreciation for a new taste.
social facilitation
theory that presence of others tends to amplify our natural behavior tendencies; explains why we over eat at celebrations.
unit bias
calories increase with portion size and we we tend to eat whole portions; smaller portion sizes explain why French weight less than us.
food variety
having access to a bunch of different or many foods stimulates eating; adaptive trait.
way to reduce consumption

Gortmaker study
study that followed 370 obese 16-to 24-year-old women over 7 year period, @ end: 2/3 of whom were still obese 7 years later, they made on average $7000 a year less that non-obese women, and they were less likely to be married.
Pingitore experiment

obesity-depression correlation
obesity contributes to depression and depression fosters obesity.
3500 calories
the energy equivalent of a pound of fat (# of calories in a pound of fat).
metabolic rate
fat has a lower rate of this b/c it takes less food energy to maintain; why require less food to maintain our weight than we did to attain it!
decreases metabolic rate
what the body does to adapt to starvation; explains why why reducing your food intake by 3500 calories may not reduce your weight by 1 pound and diet plateaus.
Bray experiment
daily food intake of obese subjects was reduced from 3500 to 450 calories but they only lost only 6 percent of their weight b/c their metabolic rates dropped about 15%.
reverse Bray experiment
volunteers were overfed an extra 1000 calories a day for eight weeks; those who gained the least weight tended to spend the extra caloric energy by fidgeting more; results suggest that lean people are naturally disposed to move about.

sexual response cycle
excitement, plateau, orgasm, and resolution (Masters and Johnson).
excitement phase
men’s and women’s genital areas become engorged with blood, a woman’s vagina expands and secretes lubricant, and her breasts and nipples may enlarge.
plateau phase
excitement peaks as breathing, pulse, and blood pressure rates continue to increase; penis becomes fully engorged and some fluid may appear at its tip; vaginal secretion continues to increase, the clitoris retracts, and orgasm feels imminent.
orgasm phase
muscle contractions take place all over the body during, accompanied by further increases in breathing, pulse, and blood pressure rates; pulse rate surges from about 70 to 115 beats per minute.
resolution phase
when the body gradually returns to its unaroused state as the engorged genital blood vessels release their accumulated blood; happens fast if orgasm has occurred, relatively slowly otherwise.

female orgasm
reinforces and facilitates conception by helping propel semen from the penis, positioning the uterus to receive sperm, and drawing the sperm further inward.
sex hormones
direct the physical development of male and female sex characteristics, and (especially in nonhuman animals) they activate sexual behavior.
sex hormones, such as estradiol, secreted in greater amounts by females than by males and contributing to female sex characteristics.
when strogen levels peak in nonhuman female mammals, promoting sexual receptivity aka state of being “in heat”; sexual desire rises slightly in women as well but they do not experience “heat”.
sex hormone that both males and females have it, but males have more of; additional amount in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty.

sexual orientation
an enduring sexual attraction toward members of either one’s own sex (homosexual orientation) or the other sex (heterosexual orientation).
____________ prevails and ____________ survives.
percent of the population is gay or lesbian.
erotic plasticity
explains why women’s sexual orientation tends to be less strongly felt and potentially more fluid and changing (aka more likely to be bi).
fraternal birth order effect
men who have older brothers are also somewhat more likely to be gay, about 1/3 more likely for each additional brother; may be caused by maternal antibodies becoming stronger w/each birth and consequently preventing the fetus’ brain from developing in a male-typical pattern.
not a sexual orientation center, but an important part of the neural pathway engaged in sexual behavior.
studied sections of the hypothalamus taken from deceased heterosexual and homosexual people and identified one cell cluster that was reliably larger in heterosexual men.
kin selection
explains how gay people’s genes live on through their supporting the survival and reproductive success of their nieces, nephews, and other relatives (who also carry many of the same genes); based in assumption that gay men make generous uncles.
“fertile females” theory
based in research that homosexual men have more homosexual relatives on their mother’s side than on their father’s; suggests that the genes that dispose women to be strongly attracted to men, and therefore to have more children, also dispose men (including some of their male relatives) to be attracted to men.

brain differences (gay-straight)
one hypothalamic cell cluster is smaller in women and homosexual men, anterior commissure is larger in gay men than straight men, gay men’s hypothalamus react as straight women’s do to the smell of sex-related hormones.
genetic influences (gay-straight)
shared sexual orientation is more common among identical than fraternal twins, sexually attraction in fruit flies can be genetically manipulated; male homosexuality appears to be transmitted from the mother’s side of the family.
prenatal influences (gay-straight)
altered prenatal hormone exposure may lead to homosexuality in humans and other animals; right-handed men w/several older brother are more likely to be gay, possibly due to a maternal immune-system reaction.
straight women and gays
most adept at remembering an object’s spatial location.

given the persistence of our traits and temperaments, we should focus not on our deficiencies, but rather on our…
interviewer illusion
overconfidence of interviewers, contributing factors: good intentions are less revealing than habitual behaviors; you don’t follow those you passed up; presumption that people are who they seem to be; preconceptions and moods lead to bias.
unstructured interviews
do provide a sense of someone’s personality (their expressiveness, warmth, and verbal ability) but they are not good predictors of future success!
