A theory in which constructs from biology and physics have been borrowed to explain complex psychosocial behaviours and interactions. Field theory takes a holistic and dynamic view of psychological events as systems of psychological energy, which can be represented mathematically. It holds that a person has personality and reacts from the very beginning as a whole. Also it views psychosocial behaviour as being the outcome of interacting forces (psychological, intellectual, emotional, and social) similar to those operating within the field theory of physics.
