Popis Dyslexia is a specific learning disorder manifested by reading difficulties such as errors in spelling and decoding words which consequently complicates the reading process and text comprehension (Gabrieli, 2009). Nowadays, a large amount of information is presented in a text form, which influences the knowledge uptake and further vocabulary expansion (Rello & Ballesteros, 2015). Repeated failures in reading can lead to reduced motivation, problems with behaviour and anxiety in children with dyslexia (Spafford & Grosser, 1996). For this reason, early diagnosis of dyslexia is crucial, which would also allow early selection of an appropriate therapy method. This would subsequently improve the pupil's adaptation to the school environment, not only in terms of the pupil's overall school performance but also in terms of the individual's social and emotional development (Nilsson Benfatto et al., 2016). Several theories try to explain the neurobiological origin of dyslexia and some of them are closely related to the visual perception and eye movements (e.g., magnocellular theory or cerebellar theory) while reading (Jošt, 2011). Eye movements can be measured via eye-tracking. Eye-tracking is a device that can provide eye movements recordings while reading. Current research shows that dyslexics have different eye movements (saccades and fixations) during reading compared to ordinary readers (e.g., Rayner, 1998; Hutzler & Wimmer, 2004). However, eye movements are not registered during the diagnostics of dyslexia in the Czech environment. The analysis of eye movements of dyslexic pupils can bring new knowledge into the field of diagnosis, possible prediction of dyslexia and also can provide a selection of appropriate therapy. The main aim of this paper is to present the results of the eye-tracking pilot study focused on eye movements aspects of dyslexic children during reading syllables and consistent text and to verify the research methodology of this study.
