[Concept formation and space perception in the blind--a summary of behavioral psychological studies]

Blindness entails an altered situation in the areas of information intake and processing concerning the aspects of perception, inter alia spatial, and concept formation. Numerous individual factors, such as life age, age at blindness onset, and occupational biography, constitute additional influences on the above cognitive faculties. A range of different study modules were used in seeking to obtain generally valid evidence relative to spatial perception and concept formation. The study overall had been directed at devising didactic and learning tools towards specific programme components. To illustrate potential applications of the study findings, the article briefly outlines a music programme guide intended for parents of blind, and possibly multi-handicapped, pre-school children.
