I think it's helpful for people to understand that different people perceive things and process them in different ways. And that different people learn in different ways. I think this helps facilitate better communication and learning. It's not uncommon for someone who perceives things or learns things in one particular way, to assume that everyone else does it in the same way.

If, for instance, I'm taking accordion lessons from someone who can hear music in his or her head, and some of my teacher's methods address this particular ability, but do not address the needs of someone who cannot hear music in in his or her head, there will be a breakdown in communication, and learning will very likely not take place.
