Interpersonal circumplex.

The social and intellectual climate of the late 1940s and early 1950s in America helped nourish humanistic, person-centered views of human behavior. During that time, psychologists such as Gordon Allport, Abraham Maslow, David McClelland, Harry Murray, and Carl Rogers emphasized the positive growth potential in human character. The psychiatrist Harry Stack Sullivan proposed that personality can best be understood within the context of interpersonal transactions, and he provided a practical, street-smart understanding of psychiatric symptoms that was quite an advance over the traditional medical and psychoanalytic viewpoints. These ideas, along with the concept of dimensionalizing traits rather than categorizing them, inspired my colleagues and I to conduct our cooperative work on the interpersonal circumplex, which culminated in the publication of my monograph. Interpersonal Diagnosis of Personality (Leary, 1957).
