Motivation & Emotion Flashcards
motives vs motivation
motives
- > needs, wants, desires that lead to a goal-directed behaviour
motivation
- > the internal and external motives that cause us to behave in a specific way
- > why we do what we do
3 motivational theories
- Drive theories
- > makes us feel balanced, if I do this I’ll be satisfied - Incentive theories
- > I will get X by doing this - Evolutionary theories
- > based on the idea that we are genetically motivated to increase the chances of passing along our genes
Drive theories
Drive Theories
- > seek homeostasis (balance/calm)
- *Drive reduction theory**
- > physiological need creates a state of tension (drive) that motivates the organism to satisfy a need
- > pushed by our internal need to reduce drive
need vs drive
- *need**
- > a deprivation that energizes the need to eliminate or reduce the deprivation
- *drive**
- > an internal state of tension because of a physiological need
incentive theories
- *regulated by external stimuli**
- > positive or negative goal with capacity to motivate behaviour (i.e. gold star, money)
- > pulled by our external incentives that lure or repel us
intrinsic vs extrinsic motivation
- *extrinsic**
- > a desire to perform a behaviour because of a promised reward (or threat of punishment)
- *intrinsic**
- > a desire to perform a behaviour for its own sake
expectancy-value model
refers to the relationship between “how likely am I to get it” and “what’s it worth to me”
evolutionary theories
motivation works to maximize reproductive success
- > only genes that promote survival of the species are preserved in the gene pool
- > natural selection favour behaviours that maximize repro success
biological factors of hunger and eating
- > regulated by the brain (hypothalamus)
- > glucose and digestive regulation is determined by blood glucose levels
hormonal controls of hunger
Appetite signaller
- > insulin
appetite suppressors
- > leptin
- > ghrelin
- > CCK
buffer window for when your body tells you you’re full
20 minutes
environmental factors of hunger and eating
- > learned preferences and habits
*anticipated pleasure of food
- > food related cues
- > stress
- > variety (you’ll eat more at a buffet than a normal breakfast bar)
- > social
characteristics of obesity
- > there are evolutionary explanations for obesity (body can’t tell between life threatening stress and normal stress, wants to stock up stores just in case)
- > there are genetic predispositions to obesity
- > set point/settling point that body wants to maintain if you lose weight
- > dietary restrains can trigger starvation mode and keep weight
stages of sex according to Masters and Johnson (1966)
hormones that regulate sex
- > estrogen
- > testosterone
- > androgens
