A reinforcement schedule where a response is reinforced only after a specific number of responses have occurred. For instance, a subject might receive a reward after exhibiting the desired behavior exactly five times. This predictable schedule often results in a high and consistent rate of responding, especially near the completion of the required number of responses, followed by a brief pause after reinforcement, sometimes referred to as a post-reinforcement pause.
This method offers a straightforward approach to behavior modification, particularly useful when establishing a consistent performance level. Historically, it has been a cornerstone of operant conditioning research, providing fundamental insights into the relationship between behavior and its consequences. Its effectiveness lies in its clarity; the required response is clearly defined, and the reward is consistently delivered after meeting that criteria.
