Horizons of Vision Research
March 6th-8th 2008

The last fifteen years of vision
research have produced several challenges to both our intuitive
conception of the nature of vision and to orthodox frameworks for
studying vision. Empirical results demonstrating blindness by
subjects to sudden changes in a visual scene (change blindness) and
blindness to unattended changes in the visual scene (inattentional
blindness) undermine the idea that the phenomenology of visual
experience at any given moment is as richly detailed and timely as
we routinely suppose. Dissociations between the ability to
discriminate and identify object shape on the basis of visual
experience and visuomotor task performance exhibited by optic
ataxics (object discrimination with impaired visuomotor skills) and
visual form agnosics (visuomotor skills without object
discrimination) have undermined the orthodox view that conscious
visual experience closely guides motor behavior. |
