Why do we eat and have sex? Flashcards
what is drive?
a psychological state of deprivation that creates a need (hunger, thirst, loneliness, boredom)
what is a need?
a necessary condition within the individual (food, water, connection, stimulation)
what are the 3 categories of needs?
physiological needs
psychological needs
implicit needs
what are examples of physiological needs?
food, arousal, water
what are the 3 psychological needs?
autonomy, competence, and relatedness (SDT)
what are the 3 implicit needs?
achievement, affiliation, power
why do we eat?
-biological reasons like energy, essential elements, and for defense
what drives hunger?
short term appetite (aka the glucostatic)
what is the glucostatic hypothesis
liver monitors blood glucose
msg to lateral hypothalamus to create hunger
msg to ventromedial hypothalamus to create satiety
long term energy balance
-lipostatic hypothesis (fat stores)
too little: grehlin triggers
too much: leptin triggers
what is homeostasis and the set point theory
our body has a genetic set point it likes to be at
- intuitive eating and eating less processed norm
-when you diet you can maintain a lower set point for a little bit but you will always rebound larger
-metabolisms can switch when we restrict, our metabolism slows down
know the model of hunger regulation
on slides
eating is a …. experience
sensory
what are some psychosocial reasons we eat or dont eat?
-celebrations
-bonding relationships
-cooperative behavior
-gender norms
know the hunger diagram
in your notes
according to the lipostatic hypothesis, what happens whn fat stores are too small
ghrelin is triggered, and the individual becomes chronically hungry in order to increase fat stores to homeostasis
according to the lipostatic hypothesis, what happens when fat stores are too large
leptin is triggered, and the individual becomes chronically not hungry in order to try and reduce the size of the fat stores to homeostasis
what are some environmental influences that may impact hunger/eating behavior?
Portion sizes, sight, smell, taste of food, and time of day
how does time of day influence eating behavior?
ghrelin peaks in the morning and then continues to peak prior to each meal
what are the 7 core processes incolved in regulation_
need (physiological)
Drive (psychological)
homeostasis
Negative feedback
Multiple inputs/Multiple outputs
intraorganismi mechanisms
extraorganismic mechanisms
what is the physiological need-psychosocial drive-behavioral cycle?
- satiated state —>
2.) physiological deprivation occurs naturally —>
3.) prolonged physiological deprivation produces bodily need —->
4.) need intensifies: gives rise to psychological drive—>
5.) goal directed motivated behavior occurs as an attempt to gratify drive
6.) consummatory behavior occurs
7.) drive is reduced
