Gestalt therapy is an existential and experiential psychotherapy that focuses on the individual's experience in the present moment, the therapist-client relationship, the environmental and social contexts in which these things take place, and the self-regulating adjustments people make as a result of the overall situation. It emphasizes personal responsibility. Gestalt therapy was co-founded by Fritz Perls, Laura Perls and Paul Goodman in the 1940s-1950s.

Edwin Nevis described Gestalt therapy as "...a conceptual and methodological base from which helping professionals can craft their practice" (Nevis, E., 2000, p. 3). In the same volume Joel Latner asserted that Gestalt therapy is built around two central ideas: that the most helpful focus of psychology is the experiential present moment and that everyone is caught in webs of relationships; thus, it is only possible to know ourselves against the background of our relation to other things (Latner, 2000). The historical development (see below) of Gestalt therapy shows the influences that have resulted in these two foci. Expanded, they result in the four chief theoretical constructs (see below under the theory and practice section) that comprise Gestalt theory and guide the practice and application of Gestalt therapy.

Gestalt therapy was forged from various influences in the times and lives of the founders: physics, Eastern religion, existential phenomenology, Gestalt psychology, psychoanalysis, theatrical performance, systems and field theory (Mackewn, 1997).

Gestalt therapy rose from its beginnings in the middle of the 20th century to rapid and widespread popularity during the decade of the 1960s and early 1970s. During the 70s and 80s Gestalt therapy training centers spread globally, but they were, for the most part, not aligned with formal academic settings. As the cognitive revolution eclipsed Gestalt therapy in psychology, many came to believe Gestalt was an anachronism. In the hands of Gestalt practitioners, Gestalt therapy became an applied discipline in the fields of psychotherapy, organizational development, social action, and eventually coaching. Until the turn of the century Gestalt therapists disdained the positivism underlying what they perceived to be the concern of research, and so, largely, ignored the need to utilize research to further develop Gestalt therapy theory and support Gestalt therapy practice. That has begun to change.

Gestalt therapy focuses more on process (what is happening) than content (what is being discussed). The emphasis is on what is being done, thought and felt at the moment rather than on what was, might be, could be, or should be.

Gestalt therapy is a method of awareness, by which perceiving, feeling, and acting are understood to be separate from interpreting, explaining and judging using old attitudes. This distinction between direct experience and indirect or secondary interpretation is developed in the process of therapy. The client learns to become aware of what they are doing psychologically and how they can change it. By becoming aware of and transforming their process they develop self acceptance and the ability to experience more in the "now" without so much interference from baggage of the past.

The objective of Gestalt therapy, in addition to helping the client overcome symptoms, is to enable him or her to become more fully and creatively alive and to be free from the blocks and unfinished issues that may diminish optimum satisfaction, fulfillment, and growth. Thus, it falls in the category of humanistic psychotherapies. Gestalt therapist could either (a) have the patient say some assertive things to members of a therapy group, or (b) give a talk on how one should never be assertive; (3) A Gestalt therapist might notice something about the non-verbal behavior or tone of voice of the client; the therapist might have the client exaggerate the non-verbal behavior and pay attention to his/her experience while doing so; (4) a Gestalt therapist might work with the breathing or posture of the client, and changes in these when the client talks about different content. Through all these means the Gestalt therapist is working with process rather than content, the How rather than the What.
