Which schedule of reinforcement is characterized by providing rewards at consistent intervals?

The correct answer is the fixed-interval schedule, which is characterized by providing reinforcement at consistent, predetermined time intervals. For example, if a worker receives a paycheck every two weeks, the reinforcement (the paycheck) is delivered on a fixed schedule. This type of reinforcement leads to a pattern of responding where the subject tends to increase their behavior as the time for reinforcement approaches, but may slow down immediately after receiving reinforcement.

This schedule is effective because individuals learn to predict when the reinforcement will occur, and it creates a regular frequency of behavior motivated by the anticipation of that reward. The timing creates a unique learning pattern that helps in understanding how behaviors can be shaped over time according to the predictable nature of the rewards.
