I've made a similar comment when this comment came out before, so my apologies to anyone who is already bored.
My take on this, based entirely on personal experience, is that there is a such thing as thinking modes, and not so much learning modes. My brain likes to operate in a visual manner, but if you're teaching me something, whether the information is presented to me visually or aurally, I will be busy constructing some sort of visual model based on what I'm receiving. Once the model appears complete and seems to work, I've learned something. Otherwise, it's time to ask some searching questions as I examine my model, and modify or destroy as appropriate.
And why this idea of learning modes is appealing to people, I think, is because people recognize their own processing modes, and naturally think that's the same thing.
As for memorization, which is a whole different thing than learning, my DW is constantly irritated by my reduced ability to recall things heard rather than seen.
