The first lever press after 10 seconds resulting in food delivery and increasing lever pressing is an example of a fixed interval reinforcement schedule.
The scenario described, where the first lever press after 10 seconds results in food delivery and increases the rate of lever pressing, is an example of a fixed interval reinforcement schedule.
In a fixed interval reinforcement schedule, a behavior is rewarded after a set amount of time.
The reinforcement occurs at regular intervals, regardless of the number of responses or the quality of the behavior.
In this case, the food delivery acts as a reinforcer, and it is only given after a fixed interval of 10 seconds.
Other examples of fixed interval reinforcement schedules include scheduled medication administration or receiving a paycheck every two weeks.
