B)by which reinforcement occurs after a varying number of responses rather than after a fixed number.

Question

Quizplus · Accepted Answer

A variable-interval schedule is a type of reinforcement schedule in which reinforcement is delivered after a random amount of time has passed. It is not based on the number of responses made, as in a variable-ratio schedule (option B), or a fixed time period (option C). The time between reinforcements fluctuates around some average rather than being fixed, as stated in option D. Therefore, option D is the correct answer.
