I'm not sure I understand your question exactly, but you might check some
work by Mel Goodale and David Milner on the patient D.F. who exhibits an
ability to perform visually-guided actions with a loss of visual form
recognition. For example, she cannot discriminate different orientations,
but she can "post a letter" in a slot of any orientation without
difficulty. Goodale views this as evidence of a dissociation of
"perception" and "action"
