chap 4- approaches to understand learning Flashcards
who first described classical conditioning
Ivan Pavlov
what is before conditioning
CS is neutral at this stage. UCS caused UCR
what is during conditioning (acquisition)
CS (originally neutral) is associated with UCS which leads to UCR
what is after conditioning
CR is created which was originally neutral. CS leads to CR. The CR is a response that’s very similar to the UCR
what is important during conditioning
CS must be presented before UCS and there must be multiple/repeated pairings
what is learning b
a relatively permanent change in behaviour due to the environment
What is the neutral stimulus (NS)
the conditioned stimulus before it becomes conditioned, it produces no relevant response
What is the conditioned stimulus (CS)
stimulus is neutral at start of conditioning. It wouldn’t normally produce the UCR but does so eventually because of its association with the UCS
What is the unconditioned stimulus (UCS)
any stimulus that consistently produced a particular involuntary/reflexive response
What is the unconditioned response (UCR)
a response which occurs automatically when the UCS is presented
What is the conditioned response (CR)
the behaviors which is identical to the UCR but is caused by the CS after conditioning.
What is extinction in classical conditioning
when UCS is no longer presented along with the CS, eventually CS becomes weaker and weaker, CR stops
What is spontaneous recovery in classical conditioning
extinction has occurred. a rest period takes place. when CS is reintroduced the CR again appears. CR is weaker than when first conditioned
what is stimulus generalization in classical conditioning
the organism only responded to the CS and no other similar stimuli.
what is stimulus discrimination in classical conditioning
the organism only responds to the CS and no other similar stimuli
what is operant conditioning
a learning process by which the likelihood of a particular behavior occurring is determined by the consequences of that behavior.
during operant conditioning when is behavior strengthened
When behavior is followed by a pleasant outcome it makes it more likely to be repeated
during operant conditioning when is behavior weakened
when behavior is followed by an unpleasant outcome it makes it less likely to be repeated
