Which schedule of reinforcement delivers the reinforcer after a fixed number of responses?

The fixed ratio schedule of reinforcement is characterized by delivering a reinforcer after a set number of responses are made. For instance, if a fixed ratio of 10 is set, the individual would receive a reinforcer after every 10 responses. This type of schedule encourages a high rate of responding since the individual knows exactly how many responses are required to earn a reward. In this way, learners can quickly and directly associate their behavior with the reinforcement they receive, which can lead to increased motivation and productivity.

Understanding this schedule is crucial in behavior analysis as it can be effectively utilized to shape and maintain desired behaviors in various settings, such as educational environments or therapeutic practices. The predictable nature of fixed schedules contrasts with other types of schedules, where either the number of responses required or the time interval between rewards varies, which can lead to different patterns of behavior.
