Sažetak

This paper presents the first reading data in Croatian collected with an eye-tracking device. The eye-tracking method allows for research into two crucial levels underlying reading: the visual and the 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. Despite the well-known definitions and vast literature on dyslexia, the neural basis of dyslexia varies greatly on the individual level. The three children studied in this paper were tested behaviorally using set of language tests for language behavior assessment on all language levels: phonology, morphology, syntax, lexicon and pragmatics. Two children had low scores on most language tests, and all three children had poor reading and writing level. Each of the children had to read two texts silently while their eye movements were recorded by means of an infrared eye-tracking system. We analyzed the number, position, and duration of fixations and the number and position of regressive (or back) saccades. Our results show intergroup differences (between a typically developing child and the three children with dyslexia), and intragroup differences (among all three children with dyslexia). The great number of fixations, longer duration of fixations, and great number of regression saccades are the main features that differentiate the children with dyslexia form the typically developing child. The only difference found between language and visual subtypes of dyslexia was a shorter duration of fixations for the child with a visual processing disorder.
