(167 cards)
1
Q
Classical conditioning
A
Learning in which a natural response (salivation) is elicited by a conditioned or learned, stimulus that previously was present in conjunction with an unconditioned stimulus;
usually deals with involuntary response
2
Q
Operant conditioning
A
Learning in which a particular action is elicited because it produces a punishment or reward;
usually deals with voluntary response
3
Q
Operant conditioning: Positive reinforcement
A
Desired reward produces action (mouse presses button to get food)
4
Q
Operant conditioning: Negative reinforcement
A
Target behavior (Response) is followed by removal of aversive stimulus (mouse presses button to turn off continuous loud noise)
5
Q
Operant conditioning: punishment
A
Repeated application of aversive stimulus extinguishes unwanted behavior
6
Q
Operant conditioning: extinction
A
discontinuation of reinforcement (+ or -) eventually eliminates behavior;
can occur in operant or classical conditioning
