Quizplus · Accepted Answer

The scalloped pattern of responding on a cumulative recorder is characteristic of a fixed interval schedule of reinforcement. This means that the subject only receives reinforcement after a set amount of time has passed, rather than after a certain number of responses. As the time interval approaches, the subject begins to increase their rate of responding, resulting in the scalloped pattern.
