Question

Quizplus · Accepted Answer

Mary's studying pattern is consistent with a fixed-interval schedule, as she starts studying more as the test approaches and her behavior is reinforced by the fixed interval of two weeks between tests. Fixed-ratio schedules would involve Mary having to complete a set amount of studying before being reinforced, variable-ratio schedules would involve reinforcement after a varying amount of studying, and variable-interval schedules would involve reinforcement after a varying amount of time. None of these schedules fit Mary's studying pattern as well as fixed-interval schedules.
