What does a Fixed Time (Noncontingent; FT/NCR) schedule involve?

A Fixed Time (Noncontingent; FT/NCR) schedule involves the delivery of a reinforcer after a predetermined amount of time has passed, regardless of the individual's behavior. This means that the reinforcement is provided based on the passing of time alone, rather than any specific behavior being exhibited. For example, if a reinforcer is set to be delivered every 5 minutes, it will be given after that timeframe has elapsed, irrespective of what the individual has done during that period.

This approach contrasts with reinforcement schedules that are contingent upon certain behaviors (like behavior frequency or completion of tasks). In a Fixed Time schedule, the timing of reinforcement is predetermined and does not require a specific response, which can lead to behaviors that may not be directly linked to the delivery of reinforcement.
