Question

Quizplus · Accepted Answer

For classical conditioning to be effective, the conditioned stimulus (CS) should be presented just prior to the unconditioned stimulus (US). This creates an association between the two stimuli, leading to the formation of a conditioned response (CR). If the CS is presented too long before or after the US, the association is weaker, and the conditioning may not be as effective. Presenting the CS at the same time as the US can lead to overshadowing, where the animal pays more attention to one stimulus over the other, and the conditioning is less effective.
