This study was intended to explore the effectiveness of cognitive enhancement training in training to ensure safe driving for older drivers. For this purpose, the difference in performance of visual and spatial working memory tasks between groups was examined by dividing the cognitive function improvement training programs into groups that were conducted wirelessly and those that were not. As a result, the change in the performance of the training group in the post-preparation period was large compared to the non-training group. This could enhance the cognitive function of older drivers, even with short term training programs, thereby suggesting the spread of training to ensure safe driving.
