| Research Abstract |
The purpose of this study is to analyze experimentally and clinically the differentiation and integration processes of visual information in the development of cognitive functions and the interaction between these processes and the signal-system activity.
Young speech-retarded children and autistic children who remained at primitive level of visual cognitive function, congenitally blind patients who received sight-restoring surgery, and brain-injured patients with various symptoms were used as the subjects for the study.
The following results were obtained: (1) Concerning speech-retarded children and autistic children, early visual cognitive behavior is related to the motivational states of the children. The signalization of sensory input is needed for the cognition of objects in communication situation. Visuo-motor coordinations play the critical role for pattern discrimination in those children. (2) Concerning the patients who recovered vision, the perception of color, form and objects is the preconditions for the cognition of human facial expression. (3) Concerning the brain-damaged patients, non-right handed aphasics and right handed crossed aphasics are found to be better in prognosis than right handed usual aphasics. In the prosopagnosic and enviromental agnosic patients with right occipital lesion, the syndoromes are attributed to the disturbance of physiognomic memory or to the dissociation of the physiognomic perception from memory rather than to the mere cognition disorders.
