Unit 3 Flashcards
(109 cards)
Neutral stimulus
stimulus which initially produces no specific response other than attention
Ex: ringing a bell for a dog to salivate
unconditioned stimulus
stimulus that naturally triggers responses without prior learning
unconditioned response
automatic, involuntary, unlearned reaction to stimulates
Ex: dog salivates at the sight of food
conditioned stimulus
previously neutral stimulus that, with repeated association with stimulus, triggers a response
conditioned response
learned behavior as response to previously neutral stimulus
acquisition
first stages of learning when a conditioned response is established
extinction
the decreased or disappearance of conditioned response
spontaneous recovery
the reappearance of conditioned response after a rest period or period of lessened response
stimulus generalization
having a conditioned response by stimulation similar but not identical to the original stimulus
stimulus discrimination
ability to distinguish between similar stimulus and only respond to specific stimuli
higher-order conditioning
conditioned stimulus used as unconditioned stimulus
conditioned + conditioned
Ex: light + bell = dog salvation for food
counterconditioning
bunny = fear, cookie = happy
bunny + cookie = happy
bunny = now happy
positive reinforcement
stimulus added + strengthens behaviors
positive punishment
stimulus added + weakens behavior
negative reinforcement
stimulus removed + negative reinforcement
negative punishment
stimulus removed + weakens behavior
variable ratio
response is reinforced after unpredictable # of responses
fixed interval
reinforcement is given after a predictable interval
fixed ratio
reinforcement given after specific # of responses
variable interval
reinforcement is presented after an unpredictable interval
Longitudinal Study
studying same group over a long period of time
cross-sectional study
data collected from people at a single point in time
Ex: different ages
teratogens
harmful substances that can interfere with normal prenatal development
Ex: alcohol, tobacco, other medication
rooting reflex
when a baby check is touched, they turn their head towards the stimulus
- seeking food
