PSYC 100 Chapter 6 Flashcards
Habituation
process of responding less strongly over time to repeated stimuli; getting used to a stimulus; usually a neutral
stimulus
Dishabituation
responding to a previously habituated stimulus
Sensitization
process of responding more strongly over time to repeated stimuli; usually a dangerous or irritating stimulus
Relaxed state more likely to get…
Habituated
Aroused state more likely to get…
Sensitized
Learning
Change in an organism’s behavior or thoughts as a result of experience
Non-Associative Learning
Responding to 1 stimulus
Associative Learning
Learning to connect or associate 2+ stimuli
Classical Conditioning
Form of learning in which two stimuli are repeatedly paired
Neutral stimulus + stimulus that elicits an automatic response
Eventually, the neutral stimulus triggers the reflex on its own
Unconditioned Stimulus
Something you already have a response to, reflex (dog food)
Unconditional Response
The response, already there not learned (salivation)
Conditioned Stimulus
Initially neutral becomes associated with the unconditioned stimulus (US) (light switch)
Conditioned Response
Automatic response triggered by conditioned stimulus (CS) (salivation)
Before conditioning
US->UR
NS->X
During conditioning
NS+US ->UR
After conditioning
CS->CR
Acquisition
Learning phase; when CS is paired with US
Extinction
CS appears alone and the CR
weakens
CR is eventually eliminated
(extinct)
Spontaneous Recovery
When a previously extinct CR suddenly emerges after a long time
Generalization
The tendency to respond to stimuli that are similar to the CS (can go too far)
Overgeneralization
When generalization goes too far
Discrimination
We learn to respond to a
particular stimulus but not to
similar stimuli (opposite of generalization)
Requirements for US-CS association to occur
Continuity, Contingency
Continuity
Shortness of time between CS and US
Contingency
Predictiveness, High likelihood of receiving US after CS
Blocking
a prior association with a conditioned stimulus prevents the learning of an association with another stimulus because the second one adds no further predictive value
Solution to Blocking
Higher order Conditioning
Higher order conditioning
Adding CS2 to CS1 shortly after, not simultaneously
Preparedness
We are more prepared to build certain associations than others.
Conditioned taste aversions
we have a strong tendency to associate
nausea with food rather than with other environmental factors
