Definitions:

Novel Stimulus

A new or unfamiliar stimulus that has not been previously experienced by an organism.

Conditioned Response

A response that is acquired due to the association of a neutral stimulus with an unconditioned stimulus, leading to a conditioned reaction.

Behavioral Contrast

A phenomenon where the rate of response to a stimulus changes when the conditions of reinforcement for another stimulus are altered.

Eyeblink Conditioning

When a conditioned stimulus (CS) becomes able to elicit a conditioned eyeblink as a result of being paired with a puff of air or a brief electrical shock below the eye.
