According to classical conditioning models of learning, what happens to the CR (conditioned response) if the CS (conditioned stimulus) is repeatedly presented by itself-that is, without the US (unconditioned stimulus) ?

A) It gets reconditioned.
B) It undergoes extinction.
C) It dishabituates.
D) It generalizes.

Classical Conditioning

A habituation method wherein two stimuli are systematically paired together; as a result, a response initially stimulated by the second stimulus is later elicited by the first stimulus on its own.

Conditioned Response

A learned response to a previously neutral stimulus that has become associated with a significant stimulus.

Conditioned Stimulus

An originally neutral signal that, upon being paired with an unconditioned stimulus, ultimately elicits a conditioned response.
