What does a fixed-interval schedule entail?

A fixed-interval schedule involves providing reinforcement after a specific period of time has passed. This means that the first response that occurs after the designated time interval is rewarded. For example, if a worker receives a paycheck every two weeks, their performance is influenced by this predictable time frame. This schedule is effective in establishing a pattern of behavior, as individuals will typically increase their efforts as the time for reinforcement approaches. The structure encourages responses as individuals learn the timing of when reinforcement will occur, which can lead to predictable patterns in behavior.
