Abstract
When testing the spatial recognition of men and women, gender differences are often observed. On the other hand, it is possible that gender differences can be reduced by training. In the U.K. and U.S., it has been reported that playing action games regularly for more than an hour a day reduces/eliminates gender differences in spatial recognition. However, in Japan, there are no empirical tests for the same purpose. Therefore, we will confirm whether the gender difference is reduced by game playing in Japan by using a MRT. The results showed that there was no significant difference in MRT by gameplay, but they did indicate the possibility of its improvement.
