Which schedule typically yields high, steady response rates with minimal pauses between reinforcements?

Which schedule typically yields high, steady response rates with minimal pauses between reinforcements?

• A. Fixed ratio
• B. Fixed interval
• C. Variable ratio
• D. Continuous schedule

Answer: (C)

Reinforcement schedules shape how often a behavior is performed. On a variable-ratio schedule, reinforcement comes after an unpredictable number of responses, so the next reward could come at any moment. This unpredictability keeps the organism responding almost continuously, producing a high and steady rate with minimal pauses between reinforcements. In contrast, fixed-ratio schedules create post-reinforcement pauses after a set number of responses; fixed-interval schedules produce bursts near the end of each time interval with gaps in between; and a continuous schedule reinforces every response, which can also lead to high rates but is not as resistant to extinction and doesn’t capture the same pattern of steady responding under variable reinforcement. Thus, the variable-ratio schedule best yields that persistent, steady responding with few interruptions.
