Answer:
of a stimulus of some sort
Explanation:
In psychology, the stimulus-response theory is used to indicate that the behavior is a consequence of the interplay between a stimulus and its corresponding response. The behaviorism states that a stimulus will produce a corresponding reaction (response) either by pairing it with a reflective trigger or by rewarding it with a response (i.e., when the stimulus is present). This current of thinking focuses on the modification in observable behaviors as a result of the learning process.
