Currently, eye movements during the reading process are viewed as a reflection of complex cognitive processes associated with the perception of the text, its semantic analysis and information processing, that is, as an indicator of human cognitive processes. The purpose of this study was to develop a diagnostic model for screening reading skills impairments due to general underdevelopment of speech and dyslexia, based on oculomotor activity patterns. For this, General Classification/Regression Tree model was used. The possibility has been revealed of using the following spatial-temporal parameters of oculomotor activity as prognostic criteria for determining the reading disorder: the average duration of fixations, the ratio of regressive saccades to the total number of saccades, the average amplitude of saccades. The accuracy of the model was 97%.
