# Gestalt therapy

Gestalt therapy is a form of psychotherapy that emphasizes personal responsibility and focuses on the individual's experience in the present moment, the therapist–client relationship, the environmental and social contexts of a person's life, and the self-regulating adjustments people make as a result of their overall situation. It was developed by Fritz Perls, Laura Perls and Paul Goodman in the 1940s and 1950s, and was first described in the 1951 book Gestalt Therapy.

## Overview

Edwin Nevis, co-founder of the Gestalt Institute of Cleveland, founder of the Gestalt International Study Center, and faculty member at the MIT Sloan School of Management, described Gestalt therapy as "a conceptual and methodological base from which helping professionals can craft their practice". In the same volume, Joel Latner stated that Gestalt therapy is built upon two central ideas:
* that the most helpful focus of psychotherapy 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 relationships to others.
The historical development of Gestalt therapy (described below) discloses the influences that generated these two ideas. Expanded, they support the four chief theoretical constructs (explained in the theory and practice section) that comprise Gestalt theory, and that guide the practice and application of Gestalt therapy.
Gestalt therapy was forged from various influences upon the lives of its founders during the times in which they lived, including the new physics, Eastern religion, existential phenomenology, Gestalt psychology, psychoanalysis, experimental theatre, systems theory, and field theory. 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 1970s 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 theory in psychology, many came to believe Gestalt was an anachronism. Because Gestalt therapists disdained the positivism underlying what they perceived to be the concern of research, they largely ignored the need to use research to further develop Gestalt theory and Gestalt therapy practice (with a few exceptions like Les Greenberg; see the interview "Validating Gestalt"). However, the new century has seen a sea change in attitudes toward research and Gestalt practice. In March 2020, Vikram Kolmannskog became the world's first Professor of Gestalt Therapy at the Norwegian Gestalt Institute, where he has been teaching and researching since 2015.
Gestalt therapy is not identical to Gestalt psychology, but Gestalt psychology influenced the development of Gestalt therapy to a large extent.
Gestalt therapy focuses on process (what is actually happening) over content (what is being talked about). The emphasis is on what is being done, thought, and felt at the present moment (the phenomenality of both client and therapist), rather than on what was, might be, could be, or should have been. Gestalt therapy is a method of awareness practice (also called "mindfulness" in other clinical domains), by which perceiving, feeling, and acting are understood to be conducive to interpreting, explaining, and conceptualizing (the hermeneutics of experience). This distinction between direct experience versus indirect or secondary interpretation is developed in the process of therapy. The client learns to become aware of what they are doing and that triggers the ability to risk a shift or change.
The objective of Gestalt therapy is to enable the client to become more fully and creatively alive and to become free from the blocks and unfinished business that may diminish satisfaction, fulfillment, and growth, and to experiment with new ways of being. For this reason Gestalt therapy falls within the category of humanistic psychotherapies. As Gestalt therapy includes perception and the meaning-making processes by which experience forms, it can also be considered a cognitive approach. Also, because Gestalt therapy relies on the contact between therapist and client, and because a relationship can be considered to be contact over time, Gestalt therapy can be considered a relational or interpersonal approach. As it appreciates the larger picture which is the complex situation involving multiple influences in a complex situation, it can also be considered a multi-systemic approach. In addition, the processes of Gestalt therapy are experimental, involving action, Gestalt therapy can be considered both a paradoxical and an experiential/experimental approach.
When Gestalt therapy is compared to other clinical domains, a person can find many matches, or points of similarity. "Probably the clearest case of consilience is between gestalt therapy's field perspective and the various organismic and field theories that proliferated in neuroscience, medicine, and physics in the early and mid-20th century. Within social science there is a consilience between gestalt field theory and systems or ecological psychotherapy; between the concept of dialogical relationship and object relations, attachment theory, client-centered therapy and the transference-oriented approaches; between the existential, phenomenological, and hermeneutical aspects of gestalt therapy and the constructivist aspects of cognitive therapy; and between gestalt therapy's commitment to awareness and the natural processes of healing and mindfulness, acceptance and Buddhist techniques adopted by cognitive behavioral therapy."$^{:174}$

## Contemporary theory and practice

The theoretical foundations of Gestalt therapy essentially rest atop four "load-bearing walls": phenomenological method, dialogical relationship, field-theoretical strategies, and experimental freedom. Although all these tenets were present in the early formulation and practice of Gestalt therapy, as described in Ego, Hunger and Aggression (Perls, 1947) and in Gestalt Therapy, Excitement and Growth in the Human Personality (Perls, Hefferline, & Goodman, 1951), the early development of Gestalt therapy theory emphasized personal experience and the experiential episodes understood as "safe emergencies" or experiments. Indeed, half of the Perls, Hefferline, and Goodman book consists of such experiments. Later, through the influence of such people as Erving and Miriam Polster, a second theoretical emphasis emerged: namely, contact between self and other, and ultimately the dialogical relationship between therapist and client. Later still, field theory emerged as an emphasis. At various times over the decades, since Gestalt therapy first emerged, one or more of these tenets and the associated constructs that go with them have captured the imagination of those who have continued developing the contemporary theory of Gestalt therapy. Since 1990 the literature focused upon Gestalt therapy has flourished, including the development of several professional Gestalt journals. Along the way, Gestalt therapy theory has also been applied in Organizational Development and coaching work. And, more recently, Gestalt methods have been combined with meditation practices into a unified program of human development called Gestalt Practice, which is used by some practitioners.
Richard G. Erskine, the originator of Integrative Psychotherapy (Developmentally Based, Relationally Focused), has written about the treatment of shame and self-righteousness in "A Gestalt therapy approach to shame and self-righteousness: theory and methods" from his book Relational Patterns, Therapeutic Presence: Concepts and Practice of Integrative Psychotherapy (2015).

### Phenomenological method

The goal of a phenomenological exploration is awareness. This exploration works systematically to reduce the effects of bias through repeated observations and inquiry.
The phenomenological method comprises three steps:
* Applying the rule of epoché - one sets aside one's initial biases and prejudices in order to suspend expectations and assumptions.
* Applying the rule of description - one occupies oneself with describing instead of explaining.
* Applying the rule of horizontalization - one treats each item of description as having equal value or significance.
The rule of epoché sets aside any initial theories with regard to what is presented in the meeting between therapist and client. The rule of description implies immediate and specific observations, abstaining from interpretations or explanations, especially those formed from the application of a clinical theory superimposed over the circumstances of experience. The rule of horizontalization avoids any hierarchical assignment of importance such that the data of experience become prioritized and categorized as they are received. A Gestalt therapist using the phenomenological method might say something like, "I notice a slight tension at the corners of your mouth when I say that, and I see you shifting on the couch and folding your arms across your chest ... and now I see you rolling your eyes back". Of course, the therapist may make a clinically relevant evaluation, but when applying the phenomenological method, temporarily suspends the need to express it.

### Dialogical relationship

To create the conditions under which a dialogic moment might occur, the therapist attends to their own presence, creates the space for the client to enter in and become present as well (called inclusion), and commits themself to the dialogic process, surrendering to what takes place, as opposed to attempting to control it. With presence, the therapist judiciously "shows up" as a whole and authentic person, instead of assuming a role, false self or persona. To be judicious, the therapist takes into account the specific strengths, weaknesses and values of the client. The only good client is a live client, so driving a client away by injudicious exposure of intolerable [to this client] experience of the therapist is obviously counter-productive. For example, for an atheistic therapist to tell a devout client that religion is myth would not be useful, especially in the early stages of the relationship. To practice inclusion is to accept however the client chooses to be present, whether in a defensive and obnoxious stance or a superficially cooperative one. To practice inclusion is to support the presence of the client, including their resistance, not as a gimmick but in full realization that this is how the client is actually present and is the best this client can do at this time. Finally, the Gestalt therapist is committed to the process, trusts in that process, and does not attempt to save themself from it.

### Field-theoretical strategies

Field theory is a concept borrowed from physics in which people and events are no longer considered discrete units but as parts of something larger, which are influenced by everything including the past, and observation itself. "The field" can be considered in two ways. There are ontological dimensions and there are phenomenological dimensions to one's field. The ontological dimensions are all those physical and environmental contexts in which we live and move. They might be the office in which one works, the house in which one lives, the city and country of which one is a citizen, and so forth. The ontological field is the objective reality that supports our physical existence. The phenomenological dimensions are all mental and physical dynamics that contribute to a person's sense of self, one's subjective experience—not merely elements of the environmental context. These might be the memory of an uncle's inappropriate affection, one's color blindness, one's sense of the social matrix in operation at the office in which one works, and so forth. The way that Gestalt therapists choose to work with field dynamics makes what they do strategic. Gestalt therapy focuses upon character structure; according to Gestalt theory, the character structure is dynamic rather than fixed in nature. To become aware of one's character structure, the focus is upon the phenomenological dimensions in the context of the ontological dimensions.

### Experimental freedom

Gestalt therapy is distinct because it moves toward action, away from mere talk therapy, and for this reason is considered an experiential approach. Through experiments, the therapist supports the client's direct experience of something new, instead of merely talking about the possibility of something new. Indeed, the entire therapeutic relationship may be considered experimental, because at one level it is a corrective, relational experience for many clients, and it is a "safe emergency" that is free to turn out however it will. An experiment can also be conceived as a teaching method that creates an experience in which a client might learn something as part of their growth. Examples might include:
* Rather than talking about the client's critical parent, a Gestalt therapist might ask the client to imagine the parent is present, or that the therapist is the parent, and talk to that parent directly
* If a client is struggling with how to be assertive, a Gestalt therapist could either:
** have the client say some assertive things to the therapist or members of a therapy group
** give a talk about how one should never be assertive
* A Gestalt therapist might notice something about the non-verbal behavior or tone of voice of the client; then the therapist might have the client exaggerate the non-verbal behavior and pay attention to that experience
* A Gestalt therapist might work with the breathing or posture of the client, and direct awareness to changes that might happen when the client talks about different content.
With all these experiments the Gestalt therapist is working with process rather than content, the how rather than the what.

## Noteworthy issues
### Self

In field theory, self is a phenomenological concept, existing in comparison with other. Without the other there is no self, and how one experiences the other is inseparable from how one experiences oneself. The continuity of selfhood (functioning personality) is something that is achieved in relationship, rather than something inherently "inside" the person. This can have its advantages and disadvantages. At one end of the spectrum, someone may not have enough self-continuity to be able to make meaningful relationships, or to have a workable sense of who they are. In the middle, their personality is a loose set of ways of being that work for them, including commitments to relationships, work, culture and outlook, always open to change where they need to adapt to new circumstances or just want to try something new. At the other end, their personality is a rigid defensive denial of the new and spontaneous. They act in stereotyped ways, and either induce other people to act in particular and fixed ways towards them, or they redefine their actions to fit with fixed stereotypes.
In Gestalt therapy, the process is not about the self of the client being helped or healed by the fixed self of the therapist; rather it is an exploration of the co-creation of self and other in the here-and-now of the therapy. There is no assumption that the client will act in all other circumstances as they do in the therapy situation. However, the areas that cause problems will be either the lack of self-definition leading to chaotic or psychotic behaviour, or the rigid self-definition in some area of functioning that denies spontaneity and makes dealing with particular situations impossible. Both of these conditions show up very clearly in the therapy, and can be worked with in the relationship with the therapist.
The experience of the therapist is also very much part of the therapy. Since we co-create our self-other experiences, the way a therapist experiences being with a client is significant information about how the client experiences themselves. The proviso here is that a therapist is not operating from their own fixed responses. This is why Gestalt therapists are required to undertake significant therapy of their own during training.
From the perspective of this theory of self, neurosis can be seen as fixed predictability—a fixed Gestalt—and the process of therapy can be seen as facilitating the client to become unpredictable: more responsive to what is in the client's present environment, rather than responding in a stuck way to past introjects or other learning. If the therapist has expectations of how the client should end up, this defeats the aim of therapy.

### Change

In what has now become a classic of Gestalt therapy literature, Arnold R. Beisser described Gestalt's paradoxical theory of change. The paradox is that the more one attempts to be who one is not, the more one remains the same. Conversely, when people identify with their current experience, the conditions of wholeness and growth support change. Put another way, change comes about as a result of "full acceptance of what is, rather than a striving to be different."

### Empty chair technique

Empty chair technique or chairwork is typically used in Gestalt therapy when a patient might have deep-rooted emotional problems from someone or something in their life, such as relationships with themselves, with aspects of their personality, their concepts, ideas, feelings, etc., or other people in their lives. The purpose of this technique is to get the patient to think about their emotions and attitudes. Common things the patient addresses in the empty chair are another person, aspects of their own personality, a certain feeling, etc., as if that thing were in that chair. They may also move between chairs and act out two or more sides of a discussion, typically involving the patient and persons significant to them. It uses a passive approach to opening up the patient's emotions and pent-up feelings so they can let go of what they have been holding back. A form of role-playing, the technique focuses on exploration of self and is used by therapists to help patients self-adjust. Gestalt techniques were originally a form of psychotherapy, but are now often used in counseling, for instance, by encouraging clients to act out their feelings helping them prepare for a new job. The purpose of the technique is so the patient will become more in touch with their feelings and have an emotional conversation that clears up any long-held feelings or reaction to the person or object in the chair.

## Historical development

Fritz Perls was a German-Jewish psychoanalyst who fled Europe with his wife Laura Perls to South Africa in order to escape Nazi oppression in 1933. After World War II, the couple emigrated to New York City, which had become a center of intellectual, artistic and political experimentation by the late 1940s and early 1950s.

### Early influences

Perls grew up on the bohemian scene in Berlin, participated in Expressionism and Dadaism, and experienced the turning of the artistic avant-garde toward the revolutionary left. Deployment to the front line, the trauma of war, anti-Semitism, intimidation, escape, and the Holocaust are further key sources of biographical influence.
Perls served in the German Army during World War I, and was wounded in the conflict. After the war he was educated as a medical doctor. He became an assistant to Kurt Goldstein, who worked with brain-injured soldiers. Perls went through a psychoanalysis with Wilhelm Reich and became a psychiatrist. Perls assisted Goldstein at Frankfurt University where he met his wife Lore (Laura) Posner, who had earned a doctorate in Gestalt psychology. They fled Nazi Germany in 1933 and settled in South Africa. Perls established a psychoanalytic training institute and joined the South African armed forces, serving as a military psychiatrist. During these years in South Africa, Perls was influenced by Jan Smuts and his ideas about "holism".
In 1936 Fritz Perls attended a psychoanalysts' conference in Marienbad, Czechoslovakia, where he presented a paper on oral resistances, mainly based on Laura Perls's notes on breastfeeding their children. Perls's paper was turned down. Perls did present his paper in 1936, but according to him, it met with "deep disapproval." Perls wrote his first book, Ego, Hunger and Aggression (1942, 1947), in South Africa, based in part on the rejected paper. It was later re-published in the United States. Laura Perls wrote two chapters of this book, but she was not given adequate recognition for her work.

### Seminal book

Perls's seminal work was Gestalt Therapy: Excitement and Growth in the Human Personality, published in 1951, co-authored by Fritz Perls, Paul Goodman, and Ralph Hefferline (a university psychology professor and sometimes-patient of Fritz Perls). Most of Part II of the book was written by Paul Goodman from Perls's notes, and it contains the core of Gestalt theory. This part was supposed to appear first, but the publishers decided that Part I, written by Hefferline, fit into the nascent self-help ethos of the day, and they made it an introduction to the theory. Isadore From, a leading early theorist of Gestalt therapy, taught Goodman's Part II for an entire year to his students, going through it phrase by phrase.

### First instances of Gestalt therapy

Fritz and Laura founded the first Gestalt Institute in 1952, running it out of their Manhattan apartment. Isadore From became a patient, first of Fritz, and then of Laura. Fritz soon made From a trainer, and also gave him some patients. From lived in New York until his death, at age seventy-five, in 1993. He was known worldwide for his philosophical and intellectually rigorous take on Gestalt therapy. Acknowledged as a supremely gifted clinician, he was indisposed to writing, so what remains of his work is merely transcripts of interviews.
Of great importance to understanding the development of Gestalt therapy is the early training which took place in experiential groups in the Perls's apartment, led by both Fritz and Laura before Fritz left for the West Coast, and after by Laura alone. These "trainings" were unstructured, with little didactic input from the leaders, although many of the principles were discussed in the monthly meetings of the institute, as well as at local bars after the sessions. Many notable Gestalt therapists emerged from these crucibles in addition to Isadore From, e.g., Richard Kitzler, Dan Bloom, Bud Feder, Carl Hodges, and Ruth Ronall. In these sessions, both Fritz and Laura used some variation of the "hot seat" method, in which the leader essentially works with one individual in front of an audience with little or no attention to group dynamics. In reaction to this omission emerged a more interactive approach in which Gestalt-therapy principles were blended with group dynamics; in 1980, the book Beyond the Hot Seat, edited by Feder and Ronall, was published, with contributions from members of both the New York and Cleveland Institutes, as well as others.
Fritz left Laura and New York in 1960, briefly lived in Miami, and ended up in California. Jim Simkin was a psychotherapist who became a client of Perls in New York and then a co-therapist with Perls in Los Angeles. Simkin was responsible for Perls's going to California, where Perls began a psychotherapy practice. Ultimately, the life of a peripatetic trainer and workshop leader was better suited to Fritz's personality—starting in 1963, Simkin and Perls co-led some of the early Gestalt workshops and training groups at Esalen Institute in Big Sur, California, where Perls eventually settled and built a home. Jim Simkin then purchased property next to Esalen and started his own training center, which he ran until his death in 1984. Simkin refined his precise version of Gestalt therapy, training psychologists, psychiatrists, counselors and social workers within a very rigorous, residential training model.

### Schism

In the 1960s, Perls became infamous among the professional elite for his public workshops at Esalen Institute. Isadore From referred to some of Fritz's brief workshops as "hit-and-run" therapy, because of Perls's alleged emphasis on showmanship with little or no follow-through—but Perls never considered these workshops to be complete therapy; rather, he felt he was giving demonstrations of key points for a largely professional audience. Unfortunately, some films and tapes of his work were all that most graduate students were exposed to, along with the misperception that these represented the entirety of Perls's work.
When Fritz Perls left New York for California, there began to be a split with those who saw Gestalt therapy as a therapeutic approach similar to psychoanalysis. This view was represented by Isadore From, who practiced and taught mainly in New York, as well as by the members of the Cleveland Institute, which was co-founded by From. An entirely different approach was taken, primarily in California, by those who saw Gestalt therapy not just as a therapeutic modality, but as a way of life. The East Coast, New York–Cleveland axis was often appalled by the notion of Gestalt therapy leaving the consulting room and becoming a way of life on the West Coast in the 1960s (see the "Gestalt prayer").
An alternative view of this split saw Perls in his last years continuing to develop his a-theoretical and phenomenological methodology, while others, inspired by From, were inclined to theoretical rigor which verged on replacing experience with ideas.
The split continues between what has been called "East Coast Gestalt" and "West Coast Gestalt," at least from an Amerocentric point of view. While the communitarian form of Gestalt continues to flourish, Gestalt therapy was largely replaced in the United States by cognitive behavioral therapy, and many Gestalt therapists in the U.S. drifted toward organizational management and coaching. At the same time, contemporary Gestalt Practice (to a large extent based upon Gestalt therapy theory and practice) was developed by Dick Price, the co-founder of Esalen Institute. Price was one of Perls's students at Esalen.

### Post-Perls

In 1969, Fritz Perls left the United States to start a Gestalt community at Lake Cowichan on Vancouver Island, Canada. He died almost one year later, on 14 March 1970, in Chicago. One member of the Gestalt community was Barry Stevens. Her book about that phase of her life, Don't Push the River, became very popular. She developed her own form of Gestalt therapy body work, which is essentially a concentration on the awareness of body processes.

#### Polsters

Erving and Miriam Polster started a training center in La Jolla, California, and published a book, Gestalt Therapy Integrated, in the 1970s.
They were influential in advancing the idea of contact boundary phenomena, which is a key part of Gestalt theory. The standard contact boundary resistances were confluence, introjection, projection, and retroflection, but the Polsters added "deflection" as a way of avoiding contact. Boundary phenomena can have good or bad effects, depending on the situation. For example, it's normal for a baby and mother to merge, but not for a therapist and client. If the therapist and client become too merged, then there can be no progress because there is no boundary for them to connect with. The client will not be able to learn anything new because the therapist will just become a part of them.

## Influences upon Gestalt therapy
### Some examples

There were a variety of psychological and philosophical influences upon the development of Gestalt therapy, not the least of which were the social forces at the time and place of its inception. Gestalt therapy is an approach that is holistic (including mind, body, and culture). It is present-centered and related to existential therapy in its emphasis on personal responsibility for action, and on the value of "I–thou" relationship in therapy. In fact, Perls considered calling Gestalt therapy existential-phenomenological therapy. "The I and thou in the Here and Now" was a semi-humorous shorthand mantra for Gestalt therapy, referring to the substantial influence of the work of Martin Buber—in particular his notion of the I–Thou relationship—on Perls and Gestalt. Buber's work emphasized immediacy, and required that any method or theory answer to the therapeutic situation, seen as a meeting between two people. Any process or method that turns the patient into an object (the I–It) must be strictly secondary to the intimate, and spontaneous, I–Thou relation. This concept became important in much of Gestalt theory and practice.
Both Fritz and Laura Perls were students and admirers of the neuropsychiatrist Kurt Goldstein. Gestalt therapy was based in part on Goldstein's concept called Organismic theory. Goldstein viewed a person in terms of a holistic and unified experience; he encouraged a "big picture" perspective, taking into account the whole context of a person's experience. The word Gestalt means whole, or configuration. Laura Perls, in an interview, denotes the Organismic theory as the base of Gestalt therapy.
There were additional influences on Gestalt therapy from existentialism, particularly the emphasis upon personal choice and responsibility.
The late 1950s–1960s movement toward personal growth and the human potential movement in California fed into, and was itself influenced by, Gestalt therapy. In this process Gestalt therapy somehow became a coherent Gestalt, which is the Gestalt psychology term for a perceptual unit that holds together and forms a unified whole.

### Psychoanalysis

Fritz Perls trained as a neurologist at major medical institutions and as a Freudian psychoanalyst in Berlin and Vienna, the most important international centers of the discipline in his day. He worked as a training analyst for several years with the official recognition of the International Psychoanalytic Association (IPA), and must be considered an experienced clinician. Gestalt therapy was influenced by psychoanalysis: it was part of a continuum moving from the early work of Freud, to the later Freudian ego analysis, to Wilhelm Reich and his character analysis and notion of character armor, with attention to nonverbal behavior; this was consonant with Laura Perls's background in dance and movement therapy. To this was added the insights of academic Gestalt psychology, including perception, Gestalt formation, and the tendency of organisms to complete an incomplete Gestalt and to form "wholes" in experience.
Central to Fritz and Laura Perls's modifications of psychoanalysis was the concept of dental or oral aggression. In Ego, Hunger and Aggression (1947), Fritz Perls's first book, to which Laura Perls contributed (ultimately without recognition), Perls suggested that when the infant develops teeth, he or she has the capacity to chew, to break food apart, and, by analogy, to experience, taste, accept, reject, or assimilate. This was opposed to Freud's notion that only introjection takes place in early experience. Thus Perls made assimilation, as opposed to introjection, a focal theme in his work, and the prime means by which growth occurs in therapy.
In contrast to the psychoanalytic stance, in which the "patient" introjects the (presumably more healthy) interpretations of the analyst, in Gestalt therapy the client must "taste" his or her own experience and either accept or reject it—but not introject or "swallow whole." Hence, the emphasis is on avoiding interpretation, and instead encouraging discovery. This is the key point in the divergence of Gestalt therapy from traditional psychoanalysis: growth occurs through gradual assimilation of experience in a natural way, rather than by accepting the interpretations of the analyst; thus, the therapist should not interpret, but lead the client to discover for him- or herself.
The Gestalt therapist contrives experiments that lead the client to greater awareness and fuller experience of his or her possibilities. Experiments can be focused on undoing projections or retroflections. The therapist can work to help the client with closure of unfinished Gestalts ("unfinished business" such as unexpressed emotions towards somebody in the client's life). There are many kinds of experiments that might be therapeutic, but the essence of the work is that it is experiential rather than interpretive, and in this way, Gestalt therapy distinguishes itself from psychoanalysis.

## Therapies influenced by Gestalt therapy

Psychotherapies influenced by Gestalt therapy include:
* Acceptance and commitment therapy
* Emotion-focused therapy

## Current status

Gestalt therapy reached a zenith in the United States in the late 1970s and early 1980s. Since then, it has influenced other fields like organizational development, coaching, and teaching. Many of its contributions have become assimilated into other schools of therapy. In recent years, it has seen a resurgence in popularity as an active, psychodynamic form of therapy which has also incorporated some elements of recent developments in attachment theory. There are, for example, four Gestalt training institutes in the New York City metropolitan area alone, in addition to dozens of others worldwide.
Gestalt therapy continues to thrive as a widespread form of psychotherapy, especially throughout Europe, where there are many practitioners and training institutions. Dan Rosenblatt led Gestalt therapy training groups and public workshops at the Tokyo Psychotherapy Academy for seven years. Stewart Kiritz continued in this role from 1997 to 2006.

### Training of Gestalt therapists
#### Pedagogical approach

Many Gestalt therapy training organizations exist worldwide. Ansel Woldt asserted that Gestalt teaching and training are built upon the belief that people are, by nature, health-seeking. Thus, such commitments as authenticity, optimism, holism, health, and trust become important principles to consider when engaged in the activity of teaching and learning—especially Gestalt therapy theory and practice.

### Associations

The Association for the Advancement of Gestalt Therapy holds a biennial international conference in various locations—the first was in New Orleans, in 1995. Subsequent conferences have been held in San Francisco, Cleveland, New York, Dallas, St. Pete's Beach, Vancouver (British Columbia), Manchester (England), and Philadelphia. In addition, the it holds regional conferences, and its regional network has spawned regional conferences in Amsterdam, the Southwest and the Southeast of the United States, England, and Australia. Its Research Task Force generates and nurtures active research projects and an international conference on research.
The European Association for Gestalt Therapy, founded in 1985 to gather European individual Gestalt therapists, training institutes, and national associations from more than twenty European nations.
Gestalt Australia and New Zealand was formally established at the first Gestalt Therapy Conference held in Perth in September 1998.

### Limitations

It has been shown that Gestalt therapy is neither designed nor intended for treatment of young adolescents, especially those who manifest severe psychiatric or behavioral disorders.
