| Abstrakt: | Objective: To explore the character of the exploratory eye movement in ADHD children. Methods: The eye mark recorder (model IV) was used to record the eye movements in 33 ADHD children and 33 normal controls matched by age and sex, using t-test to compare the differences of the numbers of eye fixations, total eye scanning lengths, mean eye scanning lengths, cognitive search scores, responsive search scores and D values between the two groups. Results: ADHD children showed significantly fewer frequent numbers of eye fixations and longer mean eye scanning lengths than the normal controls. The responsive search score of ADHD children was significantly lower than that of the control group. ADHD children had a positive D value and the normal controls had a negative D value. Conclusion: ADHD children had fewer frequent numbers of eye fixation, longer mean eye scanning length and lower responsive search score than the normal controls, which may be the evidence of executive dysfunctions. |
