Classical Conditioning

An acquisition of knowledge through the consistent coupling of two stimuli, wherein a response originally induced by the second stimulus is ultimately induced by the first stimulus on its own.

Conditioned Stimulus

An initially neutral stimulus that, after being associated with an unconditioned stimulus, elicits a conditioned response.

Unconditioned Stimulus

A stimulus that naturally triggers a reflexive response without any prior learning in classical conditioning.
