Exam III (Chapters 11, 12, and 13) Flashcards
motivation
a need or desire that energizes our behavior and directs it to a goal
instinct theory
our instincts are the source of our motivators
arousal theory
human motivation seeks optimum levels of arousal
drive reduction theory
a physical need creates an aroused state (drive) that motivates someone to satisfy the need
does NOT include sex drive
maslow’s hierarchy of needs
once the lower need is met, one moves to the next
example of self-transcendence (maslow’s hierarchy of needs)
social justice involvement, charity

example of physiological (maslow’s hierarchy of needs)
hunger, thirst
role of hypothalamus in hunger
releases appetite-related hormones
arcuate nucles (in the hypothalamus)
secretes appetite-stimulating hormones
does the hypothalamus secrete any appetite suppressing hormones?
yes
glucose
triggers feelings of hunger when low
stomach contractions
the feeling of hunger pangs
insulin
increases in insulin decrease blood glucose, which trigger hunger
leptin
protein hormone secreted by fat cells, when abundant, causes brain to increase metabolism and decrease hunger
IN TOPOMAX!!!
PYY
suppresses appetite
orexin
hunger-triggering hormone secreted by the hypothalamus
ghrelin
hunger-triggering hormone secreted by empty stomach
obesity
the condition of being grossly overweight or fat
set point theory
the point at which your weight “thermostat” is set
when your body fat goes above or below this point, your body will compensate to get back to its set point
basal metabolic rate
body’s resting rate of energy output, determined partly by genetics
anorexia nervosa
medically underweight for age, gender, and height; intense fear of becoming overweight; distorted body image
subtypes of anorexia nervosa
restricting (do not eat), binge-eating purging (eat a lot of food, then purge)
most common age of onset for anorexia nervosa
17 years old
dx checklist for anorexia nervosa
- must be medically underweight
- purposely takes in too little nourishment
- intense fear of gaining weight and seeks to prevent gaining weight despite low body weight
- has a distorted body perception, places inappropriate emphasis on weight or shape in self-judgement, or fails to appreciate serious implications of their low weight
t or f
people with anorexia usually struggle with control issues, perfectionism, depression, and/or OCD
true
treatment for anorexia
SSRIs
bulimia nervosa
binge-eating episodes and behaviors to lose weight that was just gained
subtypes of bulimia nervosa
purging-type (forced vomiting, misused laxatives), nonpurging-type (fasting, exercising frantically)
dx checklist for bulimia
- repeated binge eating episodes, feeling out of control (avg binge is 1500-10000 calories in one sitting)
- repeated performance of ill-advised compensatory behaviors to prevent weight gain
- symptoms take place at least weekly for a period of 3+ months
- inappropriate influence of weight and shape on appraisal of oneself
t or f
depression, anxiety, and substance abuse disorders are common with bulimia
true
why does bulimia usually occur?
stress
more than 1/3 of people with bulimia have _________
borderline personality disorder; impulsivity is an issue
treatment for bulimia
SSRIs
are people with bulimia usually underweight?
no- they are usually a normal weight or overweight
who are bulimia and anorexia diagnosed more in?
women
binge eating disorder
repeated binges with no control with no weight gain prevention
how much of people with binge eating disorder are overweight or obese
2/3
dx checklist for binge eating disorder
- recurrent binge-eating episodes
- binge episodes include at least 3 of the following:
+ unusually fast eating
+ absence of hunger
+ uncomfortable fullness
+ secret eating due to sense of shame
+ subsequent feelings of self-disgust, depression, or severe guilt - significant distress
- binge-eating episodes take place at least weekly over the course of 3 months
- absence of excessive compensatory behaviors
t or f
bulimia and anorexia are not diagnosed between men and women
false
they are equally diagnosed
sexual response cycle
excitement → plateau → orgasm → resolution
excitement (sexual response cycle)
getting aroused
plateau (sexual response cycle)
excitement has peaked, levels off temporarily, orgasm feels imminent
orgasm
peaks of sexual pleasure, tension released
resolution (sexual response cycle)
the body goes back to baseline
refractory period (resolution, sexual response cycle)
only men have one- they can not physically have another orgasm
younger men- a few minutes; older men- few days
hormones
men- testosterone
women- estrogen
large hormonal shifts affect sex drives
sexual disorders
impotence, erectile disorder, premature ejaculation, female orgasmic disorder
erectile disorder
inability to attain or maintain an erection
can be psychological or physical (decided which one through a REM test)
treatment: inflatable penile implant thing, viagra
premature ejaculation
sexual climax occurs before he wishes with minimal stimulation or shortly after penetration
treatment: stop/start method, squeeze technique
female orgasmic disorder
feel like they have the inability to have an orgasm
paraphilias
experiencing sexual arousal from fantasies, behaviors, or urges involving nonhuman objects, the suffering of self or others, and other non-consenting persons (i.e. voyeurism, pedophilia, transvestic fetishism)
homosexual
attracted to one’s own sex
heterosexual
attracted to people of the other sex
bisexual
attracted to both sexes
gay-straight brain differences
hypothalamic cell cluster is smaller in women and gay men than straight men
gay men’s hypothalamus reacts the same way as straight women’s to the smell of sex-related hormones
genetic influences of sexual orientation
identical twins have the same sexual orientation more frequently than fraternal
sexual attraction in fruit flies can be manipulated
male homosexuality appears to be transmitted from the mother’s side of the family
parental influences of sexual orientation
altered prenatal hormone exposure may lead to homosexuality
men with several older biological brothers are more likely to be gay
affiliation need in humans
humans are innately social beings, our need to belong affects our thoughts, emotions, and behaviors
the pain of being shut out
real pain is experienced in social isolation (anterior cingulate cortex- pain response area - is activated), social exclusion may interfere with empathy for others, increase aggression, or raise the risk for self-defeating behavior or underperformance
the net result
social media, phones, etc., have been shown to have a positive correlation with declining mental health
intrinsic motivation
motivated to complete the task because it is fun (e.g. playing volleyball)
extrinsic motivation
motivated to complete the task because we are rewarded for it (e.g. working a job for money)
task vs social & directive vs nondirective leaders
task- good at keeping members on task, have a directive/authoritarian leadership style
social- focus on morale, have a nondirective/nonauthoritarian or democratic leadership style
psychologically distant leaders
positive correlation between psychological distance and productivity
if employees are closer with their bosses, they are less productive
if employees are more distant, they are more formal
emotions
adaptive responses that support survival
three components of emotions
bodily arousal, expressive behaviors, conscious experiences
james-lange theory of emotion
arousal comes before emotion
cannon-bard theory of emotion
arousal and emotions happen at the same time
schachter’s two-factor theory
arousal and label = emotion
- emotions have two ingredients: physical arousal and cognitive appraisal
- arousal fuels emotion, cognition channels it
zajonc and ledoux theory of emotion
some emotional responses involve no deliberate thinking; they bypass the cortex and go straight to the amygdala
