Questions: Question 21 4 pts A baby who has been given 100 presentations of a high-pitched tone no longer reacts to the sound by stopping the sucking response. When a lowpitched tone is presented, the baby does stop sucking. This cessation of sucking caused by the new tone is called dishabituation. disinhibition. habituation. a conditioned response.

The answer is the first one: dishabituation.

Explanation for each option:

1. Dishabituation: This term refers to the recovery of a response that has undergone habituation, typically due to the presentation of a new stimulus. In this scenario, the baby initially stops reacting to the high-pitched tone after repeated presentations, indicating habituation. When a new, low-pitched tone is introduced, the baby stops sucking again, which is a classic example of dishabituation.

2. Disinhibition: This term is generally used in the context of a previously inhibited response reappearing due to the removal of an inhibitory influence. It is not the correct term for the situation described, as the baby's response is not about inhibition but rather about a renewed reaction to a new stimulus.

3. Habituation: This is the process by which an organism decreases or ceases its responses to a stimulus after repeated presentations. In this case, the baby has habituated to the high-pitched tone, but the question is about the response to the new tone, which is not habituation.

4. A conditioned response: This term is used in classical conditioning to describe a learned response to a previously neutral stimulus. The scenario described does not involve conditioning but rather a change in response due to a new stimulus, so this is not the correct answer.

In summary, the cessation of sucking caused by the new low-pitched tone is best described as dishabituation.
