Personality Theory in Gestalt Theoretical Psychotherapy: Kurt Lewin’s Field Theory and his Theory of Systems in Tension Revisited

With regard to the dynamics of human experience and behavior, Gestalt theoretical psychotherapy (GTP) relies mainly on Kurt Lewin’s dynamic field theory of personality. GTP is carried out by including a re-interpretation of Lewin’s theory in some aspects of psychotherapeutic practice in relation to critical realism. Human experience and behavior are understood to be functions of the person and the environment (including the other individuals therein) in a psychic field (life space), which encompasses both of these mutually dependent factors. The anthropological model of this approach is, therefore, not mono-personal but, a priori, structural and relational in nature. It does not one-sidedly focus on the “inner components” of a person, but on the interrelation of the individual and a given environment, which affects experience and behavior. After a brief introduction of these basic concepts, this lecture will focus especially on Lewin’s concept of tension-systems, which may be considered as the Gestalt theoretical counterpart of Freud’s drive theory. Further, we define the basic assumptions which underlie GTP and explain how the person moves through her/his life experience in terms of Gestalt psychology.
