A cumulative record showing regular,scalloped-shaped variation is characteristically produced by

Question

Quizplus · Accepted Answer

The regular, scalloped-shaped variation in cumulative records is typically seen with fixed interval reinforcement schedules. This is because during a fixed interval schedule, the reinforcement is only given after a certain amount of time has passed, and the response rate tends to increase as the time of the next reinforcement approaches. As a result, there is a slow rate of responding immediately after reinforcement, a rapid increase as the interval draws to a close, and then a decline in responding immediately after reinforcement is given again. This pattern creates the characteristic scalloped shape in the cumulative record. None of the other options listed would produce this pattern of responding.
