Question

Quizplus · Accepted Answer

A variable-interval schedule reinforces a behavior after unpredictable time intervals. In this case, studying for surprise quizzes is reinforced after an unpredictable amount of time has passed between quizzes. The other options do not fit because a fixed-interval schedule reinforces after a set amount of time has passed, a fixed-ratio schedule reinforces after a set number of behaviors, and a variable-ratio schedule reinforces after an unpredictable number of behaviors.
