Eye-movements and sequential tracking in dyslexic and control children.

The efficiency of eye-movements while tracking sequential lights was compared for 15 dyslexic children and 15 controls, matched on age and non-verbal intelligence. Contrary to Pavlidis (1981), no significant differences were found between the two groups on two measures of efficiency. A hierarchical cluster analysis did not demonstrate unique patterns of errors for dyslexics, with the exception of a single female dyslexic.
