Gestalt therapy is a phenomenological-existential therapy founded by Frederick (Fritz) and Laura Perls in the 1940s. It teaches therapists and patients the phenomenological method of awareness, in which perceiving, feeling, and acting are distinguished from interpreting and reshuffling preexisting attitudes. Explanations and interpretations are considered less reliable than what is directly perceived and felt. Patients and therapists in Gestalt therapy dialogue, that is, communicate their phenomenological perspectives. Differences in perspectives become the focus of experimentation and continued dialogue. The goal is for clients to become aware of what they are doing, how they are doing it, and how they can change themselves, and at the same time, to learn to accept and value themselves.
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.
