| Research Abstract |
Various kinds of cases with cognitive disability (early or congenitally blind patients who received surgery, cases with cerebral lesion, the handicapped children and developmental retardation child) were followed up, in order to investigate experimentally and longitudinally on their activity of sign-system.
Main results obtaned so far were as follows.
(1) In the cases of the congenitally blind who received surgery, their visual localization activity has much improved, although it has left something to be trained.
(2) As for subjects who reported a complete impairment in binocular stereopsis, various kinds of stereograms were used to assess their capacity for stereoscopic vision. After repeatedly presenting these stereograms, they have exhibited a tendency to restore the ability for stereopsis.
(3) We found the specific spatial memory deficit in a patient with retrosprenial cortical lesion and discussed the relation between that area and the memory circuit.
(4) We compared the symbolic functions of severe aphasics with those of nonaphasic dementias and demonstrated that some aspects of symbolic function were preserved in some severe aphasics.
(5) In the cases of the brain damaged or the congenitally blind after surgery who were unable to recognize human faces, their visual activity for face identification has gradually improved, through a long-term of training.
