Field theory (psychology)
Field theory is a psychological theory (more precisely: Topological and vector psychology) which examines patterns of interaction between the individual and the total field, or environment. The concept first made its appearance in psychology with roots to the holistic perspective of Gestalt theories. It was developed by Kurt Lewin, a Gestalt psychologist, in the 1940s.
Lewin's field theory can be expressed by a formula: B = f(p,e), meaning that behavior (B) is a function of the person (p) and their environment (e).
Early philosophers believed the body to have a rational, inner nature that helped guide our thoughts and bodies. This intuitive force, our soul, was viewed as having supreme control over our entire being. However, this view changed during the intellectual revolution of the 17th century. The mind versus the body was a forever evolving concept that received great attention from the likes of Descartes, Locke and Kant. From once believing that the mind and body interact, to thinking the mind is completely separate from the body, rationalist and empirical views were deeply rooted in the understanding of this phenomenon. Field Theory emerged when Lewin considered a person's behavior to consist of many different interactions. He believed people to have dynamic thoughts, forces, and emotions that shifted their behavior to reflect their present state.
Kurt Lewin's influence
Kurt Lewin was born in Germany in 1890. He originally wanted to pursue behaviorism, but later found an interest in Gestalt psychology while volunteering in the German army in 1914. His early experiences substantially influenced the development of his field theory. Lewin's field theory emphasized interpersonal conflict, individual personalities and situational variables and he proposed that behavior is the result of the individual and their environment. In viewing a person's social environment and its effect on their dynamic field, Lewin also found that a person's psychological state influences their social field.
Wanting to shift the focus of psychology away from the Aristotle views and more towards Galileo's approach, he believed psychology needed to follow physics. Drawing from both mathematics and physics, Lewin took the concept of the field, the focus of one's experiences, needs, and topography to map spatial relationships. Lewin created a field theory rule that says analysis can only start with the situation represented as a whole, so in order for change to take place, the entire situation must be taken into account. There seems to be a repetition of people having the same unsuccessful attempts to grow and develop themselves and field theory draws the conclusion that this repetition comes from forces within our fields. To display this psychological field, Lewin constructed "topological maps" that showed inter-related areas and indicated the directions of people's goals.
The life space
The idea that an individual's behavior, at any time, is manifested only within the coexisting factors of the current "life space" or "psychological field." So a life space is the combination of all the factors that influences a person's behavior at any time. Therefore, behavior can be expressed as a function of the life space B=ƒ(LS). Furthermore, the interaction of the person (P), and the environment (E) produces this life space. In symbolic expression, B=ƒ(LS)=F(P,E). An example of a more complex life-space concept is the idea that two people's experience of a situation can become one when they converse together. This does not happen if the two people do not interact with each other, such as being in the same room but not talking to each other. This combined space can be "built" up as the two people share more ideas and create a more complex life-space together.
The environment as demonstrated in the life space, refers to the objective situation in which the person perceives and acts. The life space environment (E) is completely subjective within each context as it depends not only on the objective situation, but also on the characteristics of the person (P). It is necessary to consider all aspects of a person's conscious and unconscious environment in order to map out the person's life space. The combined state, influenced by the environment as well as the person's perspective, conscious, and unconscious, must be viewed as a whole. While each part can be viewed as a separate entity, to observe the totality of the situation one must take all inputs into consideration.
Lewin applied the term person in three different ways.
- Properties/characteristics of the individual. (needs, beliefs, values, abilities)
- A way of representing essentially the same psychological facts of "life space" itself.
- "The behaving self".
The development of the person inevitably affects the life space. As a person undergoes changes with their body or their image of themselves changes, this can cause an instability in the region of life space. Additionally, an instability in the psychological environment or life space can lead to the instability of the person.
Any change within the life space subject to psychological laws. Accordingly, an action of the person (P) or a change in the environment (E) resulting from said action, can be considered behavior (B). These behaviors can make large or small influences on the totality of the life space. Regardless, they must be taken into consideration. Field theory holds that behavior must be derived from a totality of coexisting facts. These coexisting facts make up a "dynamic field", which means that the state of any part of the field depends on every other part of it. This not only includes both mental and physical fields, but also unseen forces such as magnetism and gravity. This can be elaborated by imagining the difference that a force can make by acting from a distance. When considering something such as the Moon's influence on the Earth, it is clear that there is an effect even though it acts from a large distance away. Behavior depends on the present field rather than on the past or the future.
Development also plays a major role in life space behavior. From the beginning of one's life behavior is molded in all respects to his or her social situation. This of course brings up the sociological discussion of nature versus nurture. Experimental psychology studies have shown the formation of aspiration, the driving factor of actions and expressions (behavior), is directly influenced by the presence or absence of certain individuals within one's life space. A child's development naturally leads to an opening up of new unknown life space regions. Transitional periods such as adolescence are characterized by a greater effect of these new regions. Therefore, an adolescent entering a new social group or life space can be seen psychologically as entering a cognitively unstructured field. This new field makes it difficult for the individual to know what behavior is appropriate within the field. This is believed to be a possibility for changes in child and adolescent behavior.
Theory and experimental evidence
According to field theory, a person's life is made up of multiple distinct spaces. Image 1 is an example of the total field, or environment. Image 2 is showing a person, and a goal they have. This image shows that there are forces pushing a person toward their goal. The dotted line is everything one must go through to reach their goal, and how one must go through many different spaces. Individuals may have the same goal, but the field to get there may be different. One's field may be adjusted in order to gain the most in life. Some fields may be deleted, and some added, all depending on certain events that occur in a persons lifetime.
Field theory also includes the idea that every person holds a different experience for a situation. This is not to say that two people's experience of an event will not be similar, but that there will be some difference. This leads to the idea that no two experiences are the same for a person either, as the dynamic field is constantly changing. This is to say that the dynamic field is like a stream, constantly flowing while changing slightly. Another piece of field theory is the idea that no part of a person's field can be viewed as being pointless. Every part of a total field must be viewed as having possible meaning and importance. This must be done regardless of how pointless or non-important the part of the field may seem, it should still be accounted for. The totality of an individual's field seems to have no bounds, as research has shown that even an infant's experience of World War II could possibly affect life later on, due to the change in field. This is a good example of how broad field theory can span, as a person's preconsciousness may be altered due to field changes that occurred before any major development.
Reception and implications
Field theory is a rather obscure aspect of Gestalt theory, a doctrine that includes many important methods and discoveries. It is a crucial building block to the foundation of Gestalt psychologists' concepts and applications. There is some confusion as to the basics of field theory, causing misconceptions of how it should be used in Gestalt therapy.
