Question

multiple choice question when a teacher uses pop quizzes and unannounced tests to determine students grades, what type of reinforcement schedule is being used? variable interval semi - continuous reinforcement fixed interval continuous reinforcement

Explanation:

In variable - interval reinforcement, the reinforcement (in this case, the pop quizzes and unannounced tests) is delivered after an unpredictable amount of time has passed. Pop quizzes and unannounced tests are not scheduled at fixed time intervals, ruling out fixed - interval. Continuous reinforcement means reinforcement after every response, which isn't the case here. There's no such standard term as semi - continuous reinforcement in basic reinforcement schedules.

Answer:

A. variable interval
