This humanistic approach, developed by Fritz Perls, grew rapidly in the United States in the 1960s. Although Perls' methodology became more and more direct, the aim from the first was that clients should learn from their own experience to acknowledge previously denied feelings and aspects of their personalities.

Well-known Gestalt techniques include increasing the awareness of "body language" and of negative internal "messages"; emphasizing the client's self-awareness by making him or her speak continually in the present tense and in the first person; concentrating on a part of a client's personality, perhaps even on just one emotion, and addressing it (or asking the client to address it) as if it were sitting by itself in the client's chair; the creation by the therapist of episodes and diversions that vividly demonstrate a point rather than explaining in words.

Such techniques are widely borrowed by other therapeutic disciplines to support their own practices. 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.

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.

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. 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.
