That makes me think about any link between gender and learning preferences. My learning preference - using various instruments - always comes up as being visual (preferably written). I much preferred reading assignments over lectures for example. I still prefer reading and I'll eschew (if possible) multimedia (in particular solely audio) methods.
I hadn't really thought of that, but you may have hit on another component of the phenomenon. But as a guy, wouldn't you prefer a power point presentation with visuals than a lecture alone? It is true that women will frequently have an easier time grasping concepts from a lecture or audio presentation than will the guys. Again there are always exceptions. Then again the guys have an easier time grasping concepts of a diagram or other written instructions showing how to assemble something complicated than the women usually will.
