The goal of the international Society is the further development of Gestalt theory in basic research as well as in application, and the encouragement and support of interdisciplinary work. The Society every other year sponsors a scientific convention, dedicated on the one hand to discussions of currently salient theoretical positions and on the other to exchange of information about ongoing Gestalt-theoretical works and projects. The languages of the congress are German and English.
A portion of the members is broken down into subgroups - work groups and a section on psychotherapy (Gestalt Theoretical Psychotherapy) -, the purpose of which is to make the mode of thought of Gestalt psychology an essential foundation and a useful basis in various fields of application. To date, these fields include psychotherapy (Gestalt Theoretical Psychotherapy), pedagogy, art and design, economics, medicine, and sport. All members are more loosely invited to participate in workshops devoted to a variety of themes.
The official publication of the GTA is the quarterly journal 'GESTALT THEORY. An International Multidisciplinary Journal' (Krammer Verlag, Vienna, ISSN 0170-057X).
Published in it are original manuscripts that serve to promote Gestalt-theoretical research and application. It also reprints classical works of historical significance that are not currently readily accessible.The gap in the further development of Gestalt-theoretical work produced by the emigration of significant Gestalt theorists during the 1930s, it is hoped, will be closed in this manner.
