The Society for Gestalt Theory and its Applications (GTA) is a prominent scientific association dedicated to advancing Gestalt theory in both academic research and practical applications. Founded in 1978 and based in Germany, the GTA boasts a diverse membership primarily composed of psychologists and psychotherapists, along with researchers from various other disciplines. The organization is committed to promoting integrative approaches to psychotherapy, exemplified by their publication, "Essentials of Gestalt Theoretical Psychotherapy," which provides valuable insights into this method.

The GTA also hosts conferences to foster collaboration and discussion within the Gestalt community, including the esteemed Metzger Award and the II. Bozzi Award. Their extensive publication, "Gestalt Theory Journal," serves as a platform for the dissemination of new research and ideas. The GTA stands as a vital hub for professionals interested in the interplay of psychology, philosophy, and the arts, contributing to the rich tapestry of human understanding and therapeutic practice worldwide.
