AB  - Ternus stimuli give rise to two mutually exclusive visual experiences: with long 
      interstimulus intervals (ISIs) the elements in the stimulus are perceived as 
      moving together as a group ('group movement'), while at shorter ISIs only a 
      single element appears to be moving ('element movement' or 'end-to-end 
      movement'). It has been hypothesized that group and element movements, 
      respectively, reflect magnocellular and parvocellular activity. On this basis, 
      Ternus tests have been used to assess magnocellular function in dyslexic 
      individuals. This use of Ternus stimuli is examined in the present report. On the 
      basis of amplitude spectra of the stimuli and of a review of previous studies it 
      is concluded that to use Ternus tests to assess magnocellular function is 
      problematic.
