philotes Posted January 24, 2012 Report Share Posted January 24, 2012 Have them stare at the dots on the nose of the female in the picture for 30 seconds. Immediately after have them stare at a white wall. ...If that doesn't do it - have them stare at it again for another 30 seconds and turn to the white wall and blink really fast. Those with HPPD should have no problem seeing the after image. Link to comment Share on other sites More sharing options...
