With the help of method of eye-tracking some characteristics of visual motor activity were studied among children of three groups: ADHD, Specific Developmental Disorders of Scholastic Skills (SDDSS), school children without learning difficulties. In the group of SDDSS a decrease in the accuracy of fixations was found in trials from the right to the left and from the top to down. In the groups of SDDSS and ADHD the children did more eye movements in all the trials in comparison with the control group. In the group of ADHD latency time of saccades is increased in the trial from down to top. In all the groups latency time of saccades was found to be increased, as well as decrease in the accuracy of fixations when doing vertical eye movements in comparison with horizontal movements.
