“…The founder of the journal Behaviorism , Willard Day, overtly sought reconciliation between radical behaviorism and phenomenology (Day, 1969). Most present day Gestalt therapists would find it incomprehensible that the coauthor who contributed the extensive personal and applied exercises (see Perls introduction, p. viii) to the original book on Gestalt Therapy (Perls, Hefferline, & Goodman, 1951) was Ralph Hefferline, an experimental psychology faculty member at Columbia and a rat running radical behaviorist in the Skinnerian tradition (Knapp, 1986). For reasons that are easy to understand today, Hefferline objected to the label “Gestalt,” preferring the term “Integrative Therapy” (Shepard, 1975, p. 63), but integration was not the order of the day and the two traditions stood far apart for decades.…”
