Classified in Psychology and Sociology

Written on in English with a size of 6.9 KB

Classical Conditioning Principles

Acquisition: The process where a stimulus elicits a conditioned response (CR). Acquisition is quicker if the stimulus is salient; the unconditioned stimulus (UCS) and conditioned stimulus (CS) are paired multiple times.

Extinction

Extinction: The elimination of the CR due to withholding the UCS; extinction is a gradual change.
