11.1 emotion and motivation

Question 1

basic motivation

Answer 1

short term goals
determined by primitive biological signals about our current needs
-ex. our brain receives info when our body requires food, and the brain directs us to fix the deficiencies

Question 2

Drives

Answer 2

stimulation that our brain generates to push us to address basic biological needs

Question 3

Homeostasis

Answer 3

processes that allow us to maintain balance in our biological systems

Question 4

Allostasis

Answer 4

processes that allow us to develop a state of readiness for anticipated future demands on our biological systems
ex. ppl might get in the habit of eating a big breakfast both to maintain energy levels after not eating anything since the previous day, homeostasis would be the goal in that case, and to ensure sufficient energy for preforming physically demanding tasks in the hours between morning and lunchtime, in that case allostasis is the goal

gives us feeling of hunger

in the ventral medial region

Question 6

statiation

Answer 6

the experience of being full and uninterested in eating any more

Question 7

glucostats

Answer 7

• the hypothalamus receives info about glucose levels based on messages sent by special neurons called glucostats
• when the hypothalamus receives info about a drop in glucose levels, it simulates feelings of hunger

Question 8

cholecystokinin or CCK

Answer 8

when we eat, expansion of our intestines stimulates neurons to release CCK. when the hypothalamus detects enough CCK it stimulates feelings of satiation

Question 9

in the bottomless bowl of soup study, ppl who had soup imperceptibly replaces at 70 % more soup

Question 12

unit bias

Answer 12

the bias to behave as though the amount of food we receive is just the right amount for us to achieve satiation

Obesity

Answer 16

an eating disorder in which ppl consume more food than they require to sustain their biological processes

the absence of control elsewhere encourages unhealthy efforts to gain control over one’s weight resulting in under eating or binging and purging

Answer 20

females that don’t feel well supported tend to binge and diet as a coping strategy
eating disorders that result in low body fat may be a way for women to reduce the chance of becoming pregnant when they are under stress or when they do not feel ready or well supported
this is possible bc low body fat suppresses menstruation- an outcome called amenorrhea

Question 21

the media is not helping us prevent eating disorders

Answer 21

thanks to insisting on displaying unattainable body shapes as the deal

• fantasy images and stories that communicate messages about beauty and ideal body shape provided by entertainment media are also not helping

``` consists of four stages -excitement -plateau -orgasm -resolution these graphs show how there is mor variability in the female cycle than the male one, bc women do not reach organism as often and bc women can sometimes have multiple orgasms without any refractory period. the typically much longer refractory period in men is the duration of time after orgasm during which having another orgasm is not possible ```

Question 28

orgasms and resolution

Answer 28

the hypothalamus generates the orgasm the point of intense pleasure and release during the sexual response cycle in both men and women -following orgasm, the hypothalamus signals the pituitary gland to release a hormone, called OXYTOCIN

Question 30

sexual orientation

Answer 30

ones preference for engaging in sexual activity with opposite sex partners (heterosexuality), same sex partners (homosexuality), either (bisexuality) and so on

Question 31

an update on the search for the cause of homosexuality

Answer 31

there has been no evidence supporting theories suggesting that homosexuality is a consequence of parenting practices or any particular type of childhood experience - brain studies have revealed that homosexual men may have a smaller hypothalamus, but that evidence is rather inconsistent and unconvincing - twin studies reveal that heritability of homosexuality is between .3 and .6, but the highest heritability estimates tend to be observed for homosexuality in men - maybe sexual orientation varies for the same complicated reasons that dining preferences vary - unfortunately, discrimination based on sexual orientation continues and likely results in underestimates of the true prevalence of homosexuality and bisexuality
