Quizplus · Accepted Answer

The unconditioned stimulus (UCS) is a naturally occurring stimulus that elicits an unconditioned response (UCR). In this scenario, the cat is serving as the UCS as it naturally causes Duke to bark (UCR). The knock and Rachel are not naturally occurring stimuli that automatically elicit a response from Duke.
