passage 3

   for some time past it has been widely accepted that babies—and other creatures—learn to do things because certain acts lead to “rewards"; and there is no reason to doubt that this is true. but it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological “drives" as thirst or hunger. in other words, a baby would learn if he got food or drink, some sort of physical comfort, not otherwise.

   it is now clear that this is not so. babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
