think spatially and stuff...

there was a comment made in my class yesterday evening that i found somewhat perplexing: some people just don't think spatially. is that kind of like colorblindness? i mean, i'm not talking about lack of depth perception, because i know that that is an actual medical condition... but do some people actually not understand space? see spatial qualities in, say, a rothko painting? maybe i'm being stupid/naive/daft, but i just can't imagine not perceiving space in two-dimensional media and the like...
