Definitions:

Classical Conditioning

A behavioral conditioning technique in which the continuous association of two stimuli results in a response that, although initially elicited by the second stimulus, is triggered by the first stimulus alone over time.

Strange Environment

An unfamiliar or unusual setting that an individual is not accustomed to, often leading to feelings of discomfort or curiosity.

Conditioned Stimulus (CS)

A stimulus that was once neutral but has become linked with an unconditioned stimulus, thereby eliciting a conditioned response over time.
