Abstract
This pilot study investigated the modifiability of perceptual deficits by training which consisted of performing microcomputer-generated video tasks. These commercially available remedial programs tapped a range of skills, such as right/left discrimination, color matching, visual scanning, judgment of line orientation, visual search, shape discrimination, visual memory, eye tracking, visuomotor coordination and visual imagery. Four subjects with acquired brain damage were given 10 h of training. Perceptual skills were assessed with a battery of 7 paper-and-pencil tests administered before and after the training. Following the training 2 subjects showed some improvement on several of the perceptual tests used, while 2 other subjects showed improvement on only a limited number of tests. Based on these results and on the performance changes on the video tasks themselves, a comprehensive evaluation of the potential benefits of this type of training on driving performance is recommended.
