What is classical conditioning?
A learning process that explains involuntary, automatic responses to stimuli
Initially described by Ivan Pavlov through studies involving dogs and salivation.
Who initially described classical conditioning?
Ivan Pavlov
What is an unconditioned stimulus (US)?
A stimulus that automatically elicits an unconditioned response (UR)
Example: meat powder in Pavlov’s studies.
What is an unconditioned response (UR)?
A natural response elicited by an unconditioned stimulus (US)
What is a conditioned stimulus (CS)?
A previously neutral stimulus that, after conditioning, elicits a conditioned response (CR)
What is a conditioned response (CR)?
A learned response to a conditioned stimulus (CS)
What is the relationship between the magnitude of a CR and a UR?
The magnitude of a CR is always less than the magnitude of the UR.
What is delay conditioning?
A procedure where the CS precedes and overlaps with the US
Most effective conditioning procedure with an optimal delay of about one-half second.
What is trace conditioning?
A procedure where the CS is presented and terminated just before the US
What is simultaneous conditioning?
A procedure where the CS and US are presented and terminated at about the same time
What is backward conditioning?
A procedure where the US is presented before the CS
Usually ineffective in establishing a CR.
What is classical extinction?
Occurs when the CS is repeatedly presented without the US, leading to no CR
What is spontaneous recovery?
The return of a CR in a reduced form after a period of time when the CS is presented alone
Suggests that extinction is a suppression of the CR, not an elimination.
What is stimulus generalization?
When stimuli similar to the original CS elicit the CR without being paired with the US
Provide an example of stimulus generalization.
Little Albert’s startle response to a white rat, which generalized to other white furry objects.
What is stimulus discrimination?
The ability to distinguish between the CS and similar stimuli
What is experimental neurosis?
Unusual behaviors observed in dogs during difficult discrimination tasks
Caused by a conflict between excitatory and inhibitory processes in the central nervous system.
What is conditioned inhibition?
A method for reducing or eliminating a CR by pairing a CS with a new neutral stimulus without the US
What is higher-order conditioning?
When a CS is paired with a neutral stimulus, making the neutral stimulus also a CS
What is compound conditioning?
Occurs when two or more stimuli are presented together
Includes blocking and overshadowing.
What is blocking in compound conditioning?
When a previously conditioned stimulus prevents the conditioning of a new stimulus
What is overshadowing in compound conditioning?
When a more salient stimulus overshadows a less salient stimulus during conditioning trials
What is the main goal of interventions based on classical conditioning?
To decrease or eliminate an undesirable behavior using extinction or counterconditioning.
Name one intervention that uses classical extinction to alter behavior.
Exposure with response prevention.
