Question

Quizplus · Accepted Answer

A variable-interval schedule involves reinforcement being given at unpredictable times, after varying amounts of time have passed. This schedule tends to produce a consistent rate of responding, with individuals typically responding steadily and at a moderate pace. In this case, because the students never know when a quiz will be given, they must study consistently in order to be prepared at all times. The unpredictability of the quiz schedule is likely to elicit a steady rate of studying from the students.
