| Research Abstract |
The authors hypothesized that the information processing behavior of orgamisms would not only depend upon the external stimulus information given at the particular time, but also upon active, information-taking-in operations of organisms, and that the information processing behavior would be formed through interactional processes of these external and internal factors, using the information/knowledge stored in the organisms. The authors also hypothesized that sign-/signal-systems of organisms could be constructed under the interactional processes. Under the above-mentioned framework, this study was to analize experimentally some conditions of the organization and disorganization in the information processing behavior, relating to the function of sign-/signal-systems. In the experiments employing rats discrimination behavior under the situation in which signals were produced by rats' activities was experimentally analyzed. It was suggested that the formation of the discrimination behavior was facilitated in the situation. Visual cognitive processes for various figures under conditions of limited visual field were examined in the experiments employing normal adults. It was found that the cognitive processes were affected by active strategies of subjects. A brain-damaged patient with difficulties in perception of speech sounds was tested with repetition and matching tasks using speech sound materials and non-speech sound materials. It was suggested that his main defect was due to decline in the rate of phonological coding processes. A cervical spine damaged patient who had completely lost somatosensory perception below his neck was tested with discrimination of weight and texture. The patient could discriminate weights using active visual and auditory cues. Some theoretical significances were discussed on the basis of these results.
