| Popis | Dyslexia is a specific learning disorder that is manifested by difficulties with reading, which is evident also in the gaze performance. This paper aims to present the results of a study that focused on the detection and analysis of specifically selected parameters of eye movements (fixations and saccades), in child dyslexic readers during the pseudo-text reading, as a part of diagnostic batteries in the Czech Republic. For these purposes, 70 participants (35 dyslexic, 35 intact) of elementary school readers in the age range of 9-10 years were measured, including eye movement detection during the performance of pseudo-text reading. Data analysis focused on parameters of fixations and saccades (i.e. fixation duration, number of fixations, saccadic amplitude, and number of regressions). These metrics were analyzed at the level of the text as a unit, individual sentences, and separate words. Results show that dyslexic readers exhibit a higher number of fixations as well as a longer fixation duration compared to intact readers. Dyslexics also perform a higher number of regressions and shorter saccadic amplitude. These results may provide new insights into the diagnostics of dyslexia, which can be followed up with precisely targeted intervention to support further development of the dyslexic reader. |
