Benedictus behavior analysis: B.F. Skinner’s magnum opus at fifty.
Abstract
This book continues to be one of the more widely read books in psychology. Skinner's magnum opus is one of a handful of books that changed the face of modern psychology. The Behavior of Organisms provided the first example of the use of the operant method to measure behavioral effects of drugs and led to the development of teaching machines, programmed instruction and community treatment programs for juvenile delinquents. The functional unit Skinner defined in his doctoral dissertation and explicated in The Behavior of Organisms remains the foundation of modern behavior analysis. The operant was defined as a class of behavior bearing characteristic probability relations with environmental events previously occurring after instances of members of that class. The Behavior of Organisms is a remarkably mature book written by the author when he was in his early 30s. The regularities and principles explicated in The Behavior of Organisms stand largely intact after half a century, and the analytic strategy has been highly effective.
