Gestalt therapy is an existential and phenomenological approach developed in the 1940s-1950s by Fritz and Laura Perls. The central premise is that people should be viewed holistically as a whole consisting of mind, body, and emotions. The initial goal of Gestalt therapy is to increase a client's awareness of what they are experiencing in the present moment. Therapists use supportive, accepting, and challenging techniques like experiments and roleplaying to help clients gain insight into their behaviors and increase present-moment awareness.
