In this paper, we describe how eyetracking has been used in exploratory experiments to inform the design of screening tests for dyslexic students by examining their eye gaze while reading Arabic texts. Findings reveal differences in the intensity of eye gaze and reading patterns between dyslexic readers and non-dyslexic controls. Dyslexics consistently exhibited longer fixation durations, shorter saccades, and more regressions. Moreover, results suggest that eye movement patterns are a reflection of the cognitive processes occurring during reading of texts in both Arabic deep and shallow orthographies. Applicability of eye movement analysis in investigating the nature of the reading problems and tailoring interventions to the particular needs of individuals with dyslexia is discussed.
