I don't think she said anything wrong.
In her defence that statement she made was highly contextual: as a direct response to someone saying that videogames cannot be used as education because of the high levels of realistic violence in them. She just gave a quick response of a completely hypothetical example where you can have the same sort of gameplay as a shooter, without the severed limbs and exploding heads.
In fact she probably deliberately made the example as girly and childish as possible to show that the games could be completely suitable to the type of people that watch My Little Pony.
That is exactly the right thing. Her research makes a point of games being able to massively improve cognitive performance. These changes are persistent for years after "game training" and improve non gaming related tasks as well.
One of the main points is that this effect should be harnessed for education and training. The only problem is that children should not be confronted with violent action games. This is a problem. When asked about this problem she replied that fast-paced action video games do not necessarily involve violent action.
Her example is a hypothetical case that could indeed work as a first person shooter game and would not rely on violence although keeping the fast paced action part. Actually non-violent FPS have already been tried (Nerf Arena Blast for example: http://en.wikipedia.org/wiki/Nerf_Arena_Blast )
The other point why she chose the princess and the magic wand is that it is infact problematic to get women to play fast-paced action games. Mostly because of the violence. She did not imply that all women want princesses and magic wands to play with.
I hope that puts her comment in perspective. She is actually doing great research and the results are abolutely amazing.
