Magno and parvo stimuli affect illusory directional hearing in normal and dyslexic readers

► Hari discovered a longer temporal window in illusory directional hearing. ► This is exacerbated in dyslexics due to a magnocellular deficit. ► We made Hari's paradigm cross-modal by adding a visual grating with each auditory click. ► We found that Parvo-activating (Magno-activating) visual stimuli enhanced (reduced) illusory hearing over no visual stimuli.
