Intermodal congruence

In perceptual physiology, intermodal consistency or intermodal congruence refers to the correspondence of the perceptual experience of two or more different sensory systems within an individual . This phenomenon forms the necessary prerequisite for the spatial orientation of living beings .

The Partial isomorphism (Strukturgleichkeit) in the evolutionary theory of knowledge is the basis for an intermodal epistemic congruence: Only due to the Passungscharakters of cognitive apparatus, in turn, is the "objective", d. H. to bring intersubjective reality into agreement with the knowledge system of the individual.

Various evidence from psychophysics even suggest that our sensory experience is constructed even more extensively within the individual brain. It is possible that our perceptions are not isomorphic images of so-called "reality" at all. However, intermodal congruence would not conflict with radical constructivism either.

According to the brain researcher Wolf Singer , the various sensory modalities in the hierarchy of the senses are accorded different powers of persuasion; In relation to primates , the following gradation results:

1. Haptic perception ,
2. Visual perception ,
3. Auditory perception ,
4. Olfactory perception .

For other living beings, completely different sensory hierarchies can apply with regard to persuasiveness.
