Kurt Levin: Field Theory
Born on: September 09, 1890
Died on: February 12, 1947
His theory is also sometimes referred to as vector psychology. Principal characteristics of Field Theory
1. Behavior is a function of the field that exists at the time the behavior occurs. 2. Analysis begins with the situation as a whole from which the component parts are differentiated.
3. The concrete person in a concrete situation can be represented mathematically. Definition of Terms
- is a function of the life space;
- B = f(L)
- The totality of coexisting facts which are conceived of as mutually interdependent. 3. Life space
-contains the totality of possible facts that are capable of determining the behavior of an individual. 4. Locomotion
-Movement that takes place when two regions are closely connected, accessible to one another and mutually influential;
- takes place when force with sufficient strength acts upon a person. 5. Needs
-Principal facts of the inner-personal region.
- Resistance of a boundary.
-Psychological means by which tension becomes equalized.
8. Psychical energy
-Kind of energy that performs psychological work.
-Equivalent to a specific intention.
-A state of the person; state of an inner-personal region relative to other inner-personal regions. 11. Valence
-A conceptual property of a region of the psychological environment. Structure of Personality
-Connections between Regions
- Number of Regions
-Person in the Environment
(P + E = Life space, L)
> Whole of psychological reality;
> Facts that exist in the region outside and adjacent to the boundary of the life space, known as the foreign hull of the life space, can materially influence the psychological environment;
> The boundary between the life space and the outer world is endowed with the property of permeability.
> Environmental facts can influence the person (P = f(E);
> Personal facts can influence the environment (E = f(P).
> includes everything that has to be known in order to understand the concrete behaviour of an individual human being in a given psychological environment at a given time.
> Outer part represents the perceptual-motor region (P-M), the central part represents the inner-personal region. > Cells adjacent to the perceptual-motor region are called peripheral cells (p); > Cells in the center of the circle are called central cells, (c). Connections between Regions
> Two regions are connected when the facts of one region are accessible to the facts of another region; > Extent of influence or accessibility between regions:
1. nearness-remoteness dimension
> place the regions close together when the influence of one upon the other is great;
> place them far apart when the influence is weak;
> Influence decreases as the number of intervening regions increases. 2. firmness-weakness dimension
> Permeability of the boundary is represented by the width of the boundary line;
> Very thin line represents a weak boundary;
> Very thick line represents an impermeable boundary.
3. fluidity-rigidity dimension
> Medium of a region is its floor or surface quality;
