AB  - In an experimental paradigm adapted from Hari (1995), forty observers listened 
      via headphones to 8 binaural clicks: 4 left-ear leading followed by 4 right-ear 
      leading with either 38 or 140 ms interstimulus intervals (ISIs). Concurrently, 
      they viewed either foveal or peripheral visual stimuli designed to activate 
      either the parvocellular or magnocellular pathway. They then reported the 
      perceived location of each click-pair. Our results replicated Hari's finding that 
      observers mistake the perceived location of short ISI click-pairs more often than 
      long. That is, when ISIs were short, the sounds seemed to play across the inside 
      of the head in a phenomenon called illusory directional hearing. However, when 
      click-pairs were accompanied by peripheral visual stimuli that activated the 
      magnocellular pathway, observers were more accurate than when there were no 
      visual stimuli. Conversely, parvocellular-activating foveal visual stimuli 
      produced more illusory hearing than when there were no visual stimuli. These 
      findings suggest that activating the slow sustained parvocellular system may 
      result in a longer processing window. Thirty dyslexic observers who repeated the 
      experimental paradigm had an even longer processing window than control observers 
      indicating that dyslexics may have a magnocellular system deficit.
