Definitions:

Conditioned Stimulus

In classical conditioning, a previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response.

Classical Conditioning

A learning process that occurs when two stimuli are repeatedly paired: a response that is initially elicited by the second stimulus is eventually elicited by the first stimulus alone.

Conditioned Response

A learned reaction to a previously neutral stimulus that has become associated with an unconditioned stimulus after conditioning.

Conditioned Stimulus

An initially neutral trigger that, following its association with an unconditioned stimulus, ultimately elicits a conditioned reaction.
