Evidence for this Comprehensive Approach to Subliminal Perception

• Is there any remaining visual functioning without a cortex?
• Blindsight (Weiskrantz et al., 1974; Weiskrantz, 1991)
  • What is it?

  

  The visual field of one eye
  
  The damaged right striate cortex

  

  Hemianopia from removal of right striate cortex

   

• Evidence of remaining visual functioning
  • Can localize information in scotoma
  • Can recognize some shapes at greater than chance
  • Can tell some colors
  • Can move eyes in direction of stimulus in damaged area
  • Backed-up with animal research

• There is some debate but mostly people believe this is real
• It certainly fits the anatomy

• So what can we conclude?
