Your calculus professor informed you at the beginning of the term that you will have eight tests-but they will all be unannounced. This is most similar to a __________ reinforcement schedule.
A) fixed interval
B) fixed ratio
C) variable interval
D) variable ratio

Question

Quizplus · Accepted Answer

The fact that the tests are unannounced means that there is no set time interval between tests (as in fixed interval) or set number of tests before reinforcement (as in fixed ratio or variable ratio). The only consistent factor is that the reinforcement (test) occurs at a variable interval of time.
