Motivation Flashcards
Instinct Theory
Automatic, involuntary behavior patterns triggered by stimuli
Fixed-Action Patterns
Unlearned, genetically coded responses to stimuli,exhibited by all members of a species
ex: nest building, bird mating dances
Evolutionary perspective
“instinctual” behaviors have evolved because they were adaptive for promoting individual survival
ex: many in animals, in humans only infant reflexes
Drive-Reduction Theory
Behavior is guided by biological needs
HOMEOSTASIS
Primary drives
(Drive-Reduction)
Stem from biological needs like food and water (unlearned)
Secondary drives
(Drive-Reduction)
Stimuli that acquires the motivational properties of primary drives
ex: farming so we do not go hungry
Arousal Theory
People seek to maintain an optimal level of physiological arousal
Yerkes-Dodson Law
A correlation between task performance and optimal level of arousal
Incentive Theory
Behavior is guided by the lure of positive incentives and the avoidance of negative incentives
-we do things just bc we like them or get something out of it
Lateral hypothalamus
Stimulation makes you hungry
Damage makes you full
-stimulate the last will make you fat
-makes us hungry
Ventromedial hypothalamus
Stimulation stops eating
Damage makes you hungry/eating
-makes us full
Stomach distention
wall stretches - send signal to brain that it is full
when stomach contacts, makes us hungry
Glucose
Have it = full
Insulin
Have it = full
Leptin
Have it = full
(Left in)=full
