Learning
|
Change in an organism's behavior or thought as a result of experience
|
Habituation
|
Process of responding less strongly over time to repeated stimuli (opposite is sensitization)
|
Classical conditioning (or Pavlovian or respondent conditioning)
|
Form of learning in which animals come to respond to a previously neutral stimulus that had been paired with another stimulus that elicits an automatic response
|
Conditioned stimulus
|
Initially neutral stimulus
|
Unconditioned stimulus
|
Stimulus that elicits an automatic response
|
Unconditioned response
|
Automatic response to a nonneutral stimulus that does not need to be learned
|
Conditioned response
|
Response previously associated with a nonneutral stimulus that is elicited by a neutral stimulus through conditioning
|
Acquisition
|
Learning phase during which a conditioned response is established
|
Extinction
|
Gradual reduction and eventual elimination of the conditioned response after the conditioned stimulus is presented repeatedly without the unconditioned stimulus
|
Spontaneous recovery
|
Sudden reemergence of an extinct conditioned response after a delay in exposure to the conditioned stimulus
|
Renewal effect
|
Sudden reemergence of a conditioned response following extinction when an animal is returned to the environment in which the conditioned response was acquired
|
Stimulus generalization
|
Process by which conditioned stimuli similar, but not identical to, the original conditioned stimulus elicit a conditioned response
|
Stimulus discrimination
|
Displaying a less pronounced conditioned response to conditioned stimuli that differ from the original conditioned stimulus
|
Higher-order conditioning
|
Developing a conditioned response to a conditioned stimulus by virtue of its association with another conditioned stimulus
|
Latent inhibition
|
Difficulty in establishing classical conditioning to a conditioned stimulus we've repeatedly experienced alone, without the unconditioned stimulus
