I think to the first order, perception must follow geometry.
I see the aspect of perception you're probably talking about
as being that which fixes up the problems which come from 
ambiguous, incomplete, and/or contradictory geometry.

I guess that's perception at work.  Most people see enlarged
objects if the pair is shot with a reduced baseline.  This is
the basis of the sport called "hypostereo".  Most people see
stretched objects if the viewpoint is too far from the prints.
