Well duh, the vast majority of the women in this study are probably all the types that don't enjoy gaming on their own to any degree, or aren't interesting enough to their partner to become more deserving of attention than a game. The second one can happen quite often I've seen.lordlee said:
Try this study again with two additional groups: hetero couples where both have a fondness for video games to a similar degree and same-sex ones where, again, both partners have a particular fondness for gaming. Then you've got an effect group, a control group and one to see if the our-brains-are-more-alike-because-we're-the-same-gender thing also comes into play.
That might be interesting.
