The year 1945 saw the culmination of many developments in psychology since the 1920s, which led to two major coalitions being formed. The first of these was represented in the reorganization of the American Psychological Association (APA). The most important aspect of this reorganization was the consensus that theory, applications, and clinical activities, formerly represented by separate organizations and carrying on their affairs at a distance from each other, were indeed all parts of a unitary entity, psychology. Psychologists advanced their own comprehensive views of behavioral science as a complex system. The perception that psychology was a united front continued to be a successful strategy, which further confirmed its presence within the spectrum of physical and social sciences. Social psychology, which in previous decades was a melange of crowd psychology and anthropological ideas, acquired a perceptual and cognitive focus.
