PSI theory (Dörner)

from Wikipedia, the free encyclopedia

The PSI theory of Dietrich Dorner is a theory of intent and action organization of man. In theory, humans are described as a self-regulating, mechanistic system that explains how and why humans behave the way they do.

description

The PSI theory traces human action back to a series of information processing processes , whereby it tries to explain the essential psychological functions such as perception , thinking , learning , emotion , motivation and memory . The theory is checked for completeness and consistency with the help of computer simulations.

Main features

The five "boilers" are central to regulation

which represent the current need and motivate to act, with competence and determination taking a special position, since they are cognitive needs and partly depend on the satisfaction of the other needs. A boiler has an outlet, an inlet and a stand knife. Based on the needs represented by the filling level of the boiler, a classification of the need can be created, which, for example, in a dangerous situation, gives more weight to the need to maintain physical integrity than to the need to satisfy hunger.

Neural Network Theory

Quad

A quadruple (short quad) is the theoretical neuron structure and the central building block of a neural network . It consists of a central neuron and the four edge neurons sub, sur, por and ret.

sur sursum upwards
sub sub under
por porro forward
ret retro backward

The edge neurons point to the central neurons of other quads and thereby form chains that can be used for various tasks, such as remembering an event, in order to find a specific memory.

Scheme

"Schemas" are the basic building blocks of our memory. A scheme is a series of neurons running in the por and ret directions, which can take on the most varied of shapes and forms. They vary from relatively simple sensory schemes such as the haptic impression of a cup, from more complex movement patterns such as grasping the cup and from entire behavioral programs that have stored the interaction with the environment, such as grasping, bringing to the mouth and drinking the cup of coffee.

Networks

The various schemes are "piled up in the memory like potatoes in a box" and are therefore disordered and inflexible. In order to systematize this random arrangement and make it usable in a meaningful way, a network of mutually referring information is formed. A scheme of a cup refers via sub to subordinate schemes, such as the haptic, visual impression, the auditory sensory impression of the word cup as well as the movement pattern that enables the word to be spoken, i.e. a subordination to an abstract scheme. A scheme such as "cup" can in turn be subordinate to several other schemes, which generates a complex system of cross-references with the wealth of experiences stored in a lifetime, which changes and creates new structures with every new experience that is incorporated.

Further development

The theory is continued mainly in the applied area by former employees, u. a. by Petra Badke-Schaub at the TU Delft (NL) in the Design Methodology Group, by Harald Schaub in the Human Factors Team at IABG , by Stefan Strohschneider in the field of intercultural communication at the University of Jena and by Rüdiger von der Weth at the HTW Dresden .
