180 children, aged 7-13, diagnosed with specific developmental disorders of scholastic skills (SDDSS) were examined in the children neurological clinic Prognoz. With the help of computer methods risk factors in the decrease in learning abilities were found out. BAER was used to measure a speed of auditory processing in the pathways of the brainstem; eye tracking was used to study characteristics of ocular motor activity; posturography – characteristics of sensory motor integration in the task of keeping balance. With the help of Ritmo-BOS, our methodical software, rhythm perception was evaluated. It was found that children with specific developmental disorders of scholastic skills have a combination of dysfunctions: 68% of children have delays in auditory processing in the brainstem; 85% have postural abnormality; 58% – an abnormal amplitude of micro saccades; 84.3% – have difficulties with rhythm reproduction. These children need a complex training designed to develop sensory motor integration in order to improve their learning abilities.
