Fear Conditioning

A learning process where an individual associates a previously neutral stimulus with an aversive event, leading to the elicitation of a fear response to the neutral stimulus.

The preoccupation or worry over a potential future event that might result in negative outcomes.

CR

In the context of classical conditioning, CR stands for Conditioned Response, which is the learned response to a previously neutral stimulus that has become associated with an unconditioned stimulus.
