During a typical morning, Daniel will check the clock more frequently as the time for his regularly scheduled lunch break approaches. In this case, Daniel's clock-checking behavior is reinforced on a schedule.

Fixed-interval schedule

Explanation:

A Fixed-interval schedule is a schedule of reinforcement where the first response is rewarded only after a specified amount of time has elapsed. This schedule causes high amounts of responding near the end of the interval but much slower responding immediately after the delivery of the reinforce.

A Fixed Interval Schedule provides a reward at consistent times.
