Hemispheres model

from Wikipedia, the free encyclopedia

The hemisphere model is a popular scientific adaptation of neuroscientific findings on the lateralization of the brain . It explains in a simplified way how the brain works , but is now viewed as outdated.

idea

The basic idea of ​​the hemisphere model is the assumption that both halves of the brain are differently specialized (for mainly rational or mainly emotional processes). It is assumed that only the left half of the brain has access to the "waking consciousness" and processes rational, linguistic, analytical, temporally linear and logical processes, while the right half of the brain is "holistic, pictorial, musical, creative, intuitive, timeless, spatial, emotional and body-oriented ”. It still partially forms the basis for psychological market research procedures .

The idea originally came from the observation that people with a severed corpus callosum often cannot read or recognize words that are presented in their left visual field, which is evaluated by the right hemisphere. This suggested that the cerebral hemispheres had separate tasks and that linguistic functions were located in the left hemisphere alone.

According to the current state of research, the hemispheres of the brain have different information processing methods along the above scheme, but these only reflect priorities or preferences, but not exclusive responsibilities. The left hemisphere of the brain is responsible for processing linguistic content in most individuals. With regard to other cognitive functions, it can be concluded that non-language functions are less lateralized. With regard to the dominance of language in the left hemisphere, recent studies have shown that the right hemisphere also plays a significant role in language processing. Köhler and Bruhn therefore come to the conclusion that “the so-called hemispheric model” is considered outdated. A good graphic representation of the current state of research can be found here under the web links.
