Explanation: Monique's response to the shaking sound is known as a conditioned response. Conditioning is simply how we adapt to our environments and a conditioned response is defined as a response to a conditioned stimulus (a stimulus that elicits a response only after learning has taken place). In other words, it is a response that has been learned.
