Conditioned Stimulus (CS)
|
The neutral stimulus that is paired with the unconditioned stimulus during classical conditioning
|
|
Second-Order Conditioning
|
A procedure in which an established conditioned stimulus is used to condition a second neutral stimulus
|
|
Stimulus Generalization
|
Responding to a new stimulus in a way similar to the response produced by an established conditioned stimulus
|
|
Stimulus Discrimination
|
Responding differently to a new stimulus than how one responds to an established conditioned stimulus
|
|
Extinction
|
Presenting a conditioned stimulus repeatedly, after conditioning, without the unconditioned stimulus, resulting in a loss of responding
|
|
Spontaneous Recovery
|
The recovery of an extinguished conditioned response after a period of nonexposure to the conditioned stimulus
|
|
Conditioned Inhibition
|
Learning that an event signals in the absence of the unconditioned stimulus
|
|
Operant Conditioning
|
A procedure for studying how organisms lear about the consequences of their own voluntary actions
|
|
Law of Effect
|
If a response in a particular situation is followed by a satisfying consequence, it will be strengthened. If a response in a particular situation is followed by an unsatisfying consequence, it will be weakened.
|
|
Discriminative Stimulus
|
The stimulus situation that sets the occasion for a response to be followed by reinforcement or punishment
|
|
Reinforcement
|
Response consequences that increase the likelihood of responding in a similar way again
|
|
Positive Reinforcement
|
An event that, when presented after a response, increases the likelihood of that response
|
|
Negative Reinforcement
|
An event that, when removed after a response, increases the likelihood of that response occurring again
|
|
Escape Conditioning
|
A situation in which a response can reduce or eliminate an unpleasant stimulus, such as when a rat escapes an ongoing shock by jumping over a barrier
|
|
Avoidance Conditioning
|
A situation in which a response can prevent the delivery of an aversive stimulus, such as when a rat learns to jump over a barrier to avoid a shock
|
|
Conditioned Reinforcer
|
A stimulus that has acquired reinforcing properties through prior learning
|
|
Punishment
|
Consequences that decrease the likelihood of responding in a similar way again
|
|
Positive Punishment
|
An event that, when presented after a response, lowers the likelihood of that response occurring again
|
|
Negative Punishment
|
An event that, when removed after a response, lowers the likelihood of that response occurring again
|
|
Schedule of Reinforcement
|
A rule that an experimenter uses to determine when particular responses will be reinforced
|
|
Partial Reinforcement Schedule
|
A schedule in which reinforcement is delivered on some of the time after the response has occurred
