Unit 6 : Theories of Motivation Flashcards
(48 cards)
Instinct/evolutionary theory
Behaviors that promote survival
Infants instinct to suck promotes survival
Drive-reduction theory
Replaced the instinct theory
Focuses on psychological needs (food + water) leads to a drive (arousal of body) which reduces the need by fulfilling it
Optimal arousal theory
Things we do just because they’re exciting. Optimal level needed
Yerkes Dodson Law
Performance increases with arousal up to a point
Hierarchy of needs
Pyramid of human needs that need to be satisfied in order to move on to the next level need
Motivation
Need/desire that directs behavior
Homeostasis
Maintain a balanced constant
Incentives
Positive or negative environment stimulus that motivate behavior
Glucose, what happens when low
Fork of sugar that circulates in blood; major form of energy
When low organs signal brain to eat
Hypothalamus + glucose
Blood vessels supply hypothalamus responds to blood levels
Insulin
Secreted by pancreas, controls blood glucose
Ghrelin
Secreted by empty stomach; sends I’m hungry to brain (growling gremlin)
Orexin
Hunger triggering secreted by hypothalamus
Leptin
Protein hormone by fat cells; when present causes brain to increase metabolism and lower hunger
PYY
Digestive track; says “I’m not hungry anymore”
Hypothalamus
Maintains bodies homeostasis + regulates hunger thirst and body temp (contains endocrine system)
Lateral hypothalamus
Large hunger, signals that we are hungry
Ventromedial hypothalamus
Very minimal hunger, signals that we had enough
Set point
Body thermostat our body restores weight back to this point
Basal metabolic rate
number of calories you burn as your body performs basic (basal) life-sustaining function.
Set point + basal metabolic rate =
Ability to lose and gain weight
Hunger depends on
Memory
Emotion
Combo of body arousal and expressive behavior
James Lang
Arousal before emotion (J before L)
