Spatial and Temporal Measurements of Eye Movement in Children with Dyslexia
This paper presents the first reading data in Croatian collected with an eye-tracking device. Eye-tracking method allows for research into two crucial levels underlying reading: visual and cognitive. The aim of this paper is to show the differences in eye movements in children with dyslexia using the principles of cognitive-control view. Namely, despite well known definitions and vast literature on dyslexia, background causes of dyslexia on the individual level are highly varied. The three children studied in this paper were tested behaviorally using set of language tests for language behavior assessment. Two children had low scores on most language tests, and all three children had poor level of reading and writing. Using SMI`s iView X Hi-Speed eye- tracking system all children had to read two texts silently while the device recorded the eye movements, i.e. fixations (number, position, duration) and saccades (number, speed, magnitude). A number of variables were analysed: number and length of fixations and number of regressive (or back) saccades. The results have shown intergroup diffferences (between typical developing child and children with dyslexia), and intragroup differences (among all theee children with dyslexia).
