In the context of reinforcement, what defines a Fixed Ratio Schedule?

A Fixed Ratio Schedule is characterized by delivering a reinforcer after a fixed number of responses have been completed. This means that reinforcement is contingent upon the organism performing a specific number of behaviors before being rewarded. For instance, if a behavior is reinforced on a fixed ratio of 5, the individual must perform the behavior five times to receive a reward.

This schedule leads to a high and consistent rate of responding, as individuals learn that their efforts directly relate to receiving reinforcement. Their motivation remains strong because they know exactly how many responses are necessary to earn the reinforcer. Thus, the definition focuses on the exact number of responses required to trigger the reinforcement, distinguishing it from other schedules that involve time or variability in response requirements.
