Playing video games erases the spatial acuity gap between men and women at least according to one study where men and women participated in an “off Man Out” game in which men scored much better than women. However, then video games entered the picture.
They asked some of their volunteers to spend ten hours playing an action-packed, shoot-’em-up video game, called “Medal of Honour: Pacific Assault”. As a control, other volunteers were asked to play a decidedly non-action-packed puzzle game, called “Ballance”, for a similar time. Both sets were then asked to do the odd-man-out test again.
Among the Ballancers, there was no change in the ability to pick out the unusual. Among those who had played “Medal of Honour”, both sexes improved their performances.
That is not surprising, given the different natures of the games. However, the improvement in the women was greater than the improvement in the men—so much so that there was no longer a significant difference between the two. Moreover, that absence of difference was long-lived. When the volunteers were tested again after five months, both the improvement and the lack of difference between the sexes remained. Though it is too early to be sure, it looks likely that the change in spatial acuity—and the abolition of any sex difference in that acuity—induced by playing “Medal of Honour” is permanent.
