In general scientists do a lot of experiments where they make predictions about learning and those predictions turn out to be false. That goes for predictions based on RL as well as prediction based on other models.

Wikipedia describes RL as:

Reinforcement learning is an area of machine learning inspired by behaviorist psychology, concerned with how software agents ought to take actions in an environment so as to maximize some notion of cumulative reward.

Given that's an area of machine learning you usually don't find psychologists talking about RL. They talk about behaviorism. There are tons of papers published on behaviorism and after a while the cognitive revolution came along and most psychologists moved beyond RL.
