This idea has been around for several decades. This
thread states the original idea, but thinking and research have evolved, and most learning experts these days would say that everyone uses all three types of learning. Some people might feel that they have *slight* preferences, but in studies, those preferences don't really hold up well.
But, from a learning and teaching perspective, most everybody DOES benefit when instruction includes approaches from two or three of those channels as opposed to instruction that focuses only on one of the three channels.
