On behavioristic versus neurophysiologic accounts of psychotic behavior

B. F. Skinner has made significant contributions to the science of the behavior of organisms, including human ones, especially through his emphasis on observable behavior. He has correctly placed psychology among the biological sciences. My disagreement with his position stems from his apparent belief that a knowledge of the pertinent neurophysiology is not necessary (though perhaps desirable) to an explanation of the behavior of an organism. I believe this is a significant conceptual shortcoming, and that correcting it will bring psychology into a more consistent position with the biological sciences in general.
