What is true about a Fixed Ratio (FR) schedule?

A Fixed Ratio (FR) schedule is characterized by delivering a reward after a specific number of responses. This means that a trainer or the reinforcement system is designed to provide reinforcement consistently after a predetermined number of correct behaviors or actions are performed by the dog. For example, in a dog training context, if the schedule is set to FR5, the dog would receive a reward after every fifth successful sit command.

This structure encourages the animal to perform the behavior consistently, as they learn the exact number of actions required to earn their reward, creating a strong association between their efforts and the reinforcement received. In contrast to variable schedules, which might lead to unpredictable reinforcement timing, the fixed ratio offers a clear and defined outcome for learning.

When considering the other choices, it becomes evident that they do not accurately define a Fixed Ratio schedule. Rewards tied to a variable number of responses pertain to a Variable Ratio (VR) schedule, while a slow response rate is typically associated with Fixed Interval schedules. Lastly, the notion of no post-reinforcement pause is characteristic of Variable Ratio schedules, where the unpredictability of reinforcement keeps the subjects engaged without pauses in action following a reward.
