Concept:Field theory explains human behavior as a product of psychological forces in an individual's life space, and it was developed by Kurt Lewin, a Gestalt psychologist.
Explanation:Kurt Lewin is considered the father of modern social psychology and a key Gestaltist.
He proposed field theory to understand how individuals perceive and react to their physical and social environment.
The theory uses the concept of "life space," which includes the person's drives, thoughts, and perceived objects.
Lewin's work focused on group dynamics and individual behavior, distinct from behaviorists, structuralists, or psychoanalysts.
Gestalt psychology's core idea is that the whole is greater than the sum of its parts, which underlies field theory.
Therefore, field theory is a contribution of the Gestalt school.
