In order to proceed with abstraction, the organism must be exposed to a sufficient number of events which contain the same factors. Only then is a person equipped to cope with the most frequent happenings that he may encounter.

The change toward larger Gestalten and the necessity of this change for both humanistic and formal reasons can be illustrated by considering Sullivan's emphasis upon the phenomena of interaction. This emphasis is very clearly part of a defense of man against the older, more mechanistic thinking which saw him so heavily determined by his internal psychological structure that he could easily be manipulated by pressing the appropriate buttons — a doctrine which made the therapeutic interview into a one-way process with the patient in a relatively passive role. The Sullivanian doctrine places the therapeutic interview on a human level, defining it as a significant meeting between two human beings. The role of the therapist is no longer to be dehumanized in terms of definable purposes which he can plan, and the role of the patient is no longer dehumanized into that of an object of manipulation"

Human sense organs can receive only news of difference, and the differences must be coded into events in time (i.e., into changes) in order to be perceptible. Ordinary static differences that remain constant for more than a few seconds become perceptible, only by scanning. Similarly, very slow changes become perceptible only by a combination of scanning and bringing together observations from separated moments in the continuum of time.
