Lecture 6c: motives for behaviour Flashcards
motivation:
a process that causes some behaviour
toward some goal, or away from some unpleasant behaviour
behaviour is mainly influenced by:
nature and nurture
drive theory
- behaviours are caused by fulfilling biological needs (drives), these can be hunger, sex, thirst, ect.
- not all the behaviour that we show is to satisfy basic biological needs alone
some biological motives in humans:
hunger, thirst, sex, excretion, temperature, activity, ect.
some social motives in humans:
achievement, affiliation, dominance, order, play, ect.
what are the categories of motivation
Extrinsic motivation: participating in an activity to gain a reward
inartistic motivation: participating in an activity for its own sake
the genetic basis of weight: set-point
a biological mechanism that is partly genetic, it maintains people’s body weight at a certain level
-it is influenced by basal metabolism rate
what is bad about obesity?
it is a costly social problem, and has major health threats
why are people becoming so overweight nowadays?
- fatty food is cheaper and tastes good
- that food is easier to make
- modern technology gives us more leisure and less exercise
- we drive instead of walk
- modern hobbies consume minimal calories
the role of genes in weight gain:
we evolved when food was scarce and starvation was a concern, therefore, we eat when food is available, and store it is fat when there is more than we need
the role of modern environment on weight gain:
food is cheap and in great abundance, unfortunately, our bodies still want to eat as much as we can and store the remaining fat
how can people fight the genetics that make them gain weight?
reducing the amount of calries that you eat will only slow down metabolism, but since exercise increases metabolism, that is the answer
what is the cultural influence of weight?
some places favour more weight, whereas some favour less, it depends on the ideal body type of the culture that the person is in.
what is the consequence of cultural ideals for body image?
bulimia, anorexia, steroids, depression and anxiety (from not living up to a certain standard)
the biological basis of sexual desire:
the hormone testosterone is important for the existence and intensity of one’s sex drive
- having sex increases testosterone levels
- castration does not eliminate sex drive
