The Brain's "New" Science: Psychology, Neurophysiology, and Constraint*

There is a strong philosophical intuition that direct study of the brain can and will constrain the development of psychological theory. When this intuition is tested against case studies from the psychology of perception and memory, it turns out that psychology has led the way toward knowledge of neurophysiology. An abstract argument is developed to show that psychology can and must lead the way in neuroscientific study of mental function. The counterintuition is based on mainly weak arguments about the fundamentality or objectivity of physics or physiology in relation to psychology.
