Definitions:

Repeated Exposure

The process of being exposed to the same stimulus or environment multiple times, affecting perceptions or behaviors.

Classical Conditioning

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

Conditioned Stimulus

A conditioned stimulus is a previously neutral stimulus that, after becoming associated with an unconditioned stimulus, eventually triggers a conditioned response.

Unconditioned Stimulus

In behavioral psychology, a stimulus that naturally and automatically triggers a response without prior conditioning.
