Since the monkey has consistently chosen the rough block in the past and has received a reward for doing so, it is likely to continue this behavior and choose the new, even rougher block when given the choice between the two. This is known as the Law of Effect, which states that behavior that is followed by a reward is more likely to be repeated in the future.
