Cognitive Science - Reward Is Not Enough?

There are different cultures of reinforcement learning that kind of correspond to the history of cognitive science, where some are closer to behaviorism. Some might be even closer to inactivism, and talking about impowerment and interaction sort of learning which is much more used in robotics. And it seems to me that perhaps reward is not enough is akin to the behaviorist culture of arel. I wonder what you think?
