Which reinforcement schedules do NOT exhibit a post-reinforcement pause?

• A. Fixed-ratio and fixed-interval
• B. Variable-ratio and variable-interval
• C. Continuous and fixed-interval
• D. Variable-ratio and fixed-interval

Answer: (B)

The correct choice identifies the reinforcement schedules that do not exhibit a post-reinforcement pause. In this context, variable-ratio and variable-interval schedules are of particular interest. Variable-ratio schedules deliver reinforcement after an unpredictable number of responses, which encourages a high and steady rate of responding due to the uncertainty regarding when the next reinforcement will occur. This unpredictability keeps individuals engaged and responding without leading to a pause after receiving reinforcement. Similarly, variable-interval schedules provide reinforcement at unpredictable time intervals. This means that, like variable-ratio schedules, individuals remain consistently engaged, as they cannot predict when reinforcement will occur, thus minimizing any likelihood of a post-reinforcement pause. In contrast, fixed-ratio and fixed-interval schedules typically result in a pause after reinforcement. In a fixed-ratio schedule, after receiving a reinforcement, individuals may take a brief break before resuming responding, as they know exactly how many responses are required for the next reinforcement. Fixed-interval schedules lead to the same behavior, where individuals respond more as reinforcement time approaches but may pause after receiving the reinforcement since the next reinforcement is predetermined in time. By recognizing the characteristics of variable-ratio and variable-interval schedules, it becomes evident why they do not lead to post-re
