2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

PERCEPTUAL FILTERS 1)3)

← Back

Any sensorial organ or part of the nervous subsystem which reduces our capacity to observe our environment.

Our five generally recognized sensory organs all act as perceptual filters. For ex., our sight cannot recognize infra-red or ultra-violet radiations, or may in some cases confuse colors (Daltonism). This renders our sight incomplete, and even in some cases unreliable.

The way sensations are translated into nervous inputs, and notably the ways these inputs are converted and become interconnected in the brain, may also produce a filtering or warping effect.

In this way, ambiguities and erroneous interpretations can appear as for example optical or auditive illusions.

Finally, some cultural traits may generate perceptual filtering effects through a different quality or level of sensorial education. As an example, the perception by Indian Raga musicians of 1/9th of tones is more acute than the Occidental perception of mere 1/2 tones.

The existence of perceptual filters is very important for any good theory of the observer.
