Understanding the “cognitive revolution” in psychology

In this paper it is argued that the “cognitive revolution” in psychology is not best represented either as a Kuhnian “paradigm shift,” or as a movement from an instrumentalist to a realist conception of psychological theory, or as a continuous evolution out of more “liberalized” forms of behaviorism, or as a return to the form of “structuralist” psychology practiced by Wundt and Titchener. It is suggested that the move from behaviorism to cognitivism is best represented in terms of the replacement of (operationally defined) “intervening variables” by genuine “hypothetical constructs” possessing cognitive “surplus meaning,” and that the “cognitive revolution” of the 1950s continued a cognitive tradition that can be traced back to the 1920s. © 1999 John Wiley & Sons, Inc.
