A rat is trained to press a lever to obtain food under a fixed-interval schedule. Which of the following behaviors would the rat most likely exhibit?

Pressing the lever continuously whenever it is hungry.

Pressing the lever exactly once and waiting for the food pellet before pressing it again.

Pressing the lever slowly at first, but with increasing frequency as the end of the interval approaches.

None of the above; the association formed by fixed-interval schedules is too weak to increase behavior.

C is the correct answer.

In a fixed-interval schedule, the desired behavior is rewarded the first time it is exhibited after the fixed interval has elapsed. Both fixed-interval and fixed-ratio schedules tend to show this phenomenon: almost no response immediately after the reward is given, but the behavior increases as the rat gets close to receiving the reward.
