True, but while this has some effect on things like handedness and lateralization of language functions, it does not predict any aspect of personality. Anyway it's a moot point, since this illusion has nothing to do with hemispheric dominance and everything to do with how we interpret 3D images on a 2D plane.

And for the record (just so that I'm not jumping in here solely to be contentious ), I've been acquainted with this illusion for many months and have yet to ever see it spin counter-clockwise...
