Do eye movements hold the key to dyslexia?

Abstract Dyslexics have been found to exhibit during reading erratic eye movement (EM) patterns and characteristics, which are different from those of all other readers. The present study shows that the dyslexics' erratic EM's are present not only in reading but also in the simple sequential task of trying to follow light sources each of which is illuminated sequentially. These results could manifest a central malfunction in dyslexics, namely sequential disability and/or oculomotor malfunction.
