| Research Abstract |
We investigated the characteristics of verbal and sensory regulation in cognitive processes of persons with intellectual disabilities by the tasks of eye movements, visual search and grip strength. Outlines of each task were as follows. 1) Eye movement task : Subjects were told to keep their eyes on the target, which moves on horizontal plane at fixed frequency, and follow it as best they could. 2) Visual search task : Subjects searched the target among distractors as soon as possible. 3) Grip strength task : Subjects were told to regulate their grip strength in obedience to verbal instructions. In eye movement task and grip strength task, subjects had to regulate their own movements by verbal instructions. These were tasks that were mainly needed verbal regulation. In visual search task, the target stood out from distractors by pop-out phenomenon, and subjects could find out the target easily. Subjects could process this task instinctively. Through tasks mentioned above there was not severe disturbance in both of verbal and sensory regulations of cognitive processes in the subjects with moderate intellectual disabilities. On the other hand results of the subjects with severe intellectual disabilities showed that they would have difficulties in both of verbal and sensory regulations of cognitive processes. These results may indicate that it would be difficult to use sensory information, which was given externally, to regulate actions for persons with severe intellectual disabilities.
