Eye tracking studies, a way to understand difficulties in reading processing
Main Article Content
Abstract
The aim of this study is to compare the features that characterise reading in Spanish, in dyslexic children and typical readers based on their eye movements, according to the different variables that characterise them: reading time, number and duration of fixations, amplitude, duration and speed of saccades, number of regressions and path length. The eye movements of 36 children aged 9-10 years (16 of whom were diagnosed with dyslexia) were studied while reading words and texts. The analysis showed significant differences in some of the variables studied. Dyslexic children perform a greater number of fixations, require more time to complete the reading task, perform shorter saccades and more regressions compared to typical readers. The average path length and the duration of fixations are similar in both groups.
