【Objective】 To reveal the characteristic of visual perception development of children with ADHD. 【Methods】 Frostig visual perception development test-II and Wechsler intelligence scale for children were tested in 41 subjects and the normal controls matched by age and gender. All subjects came from the psychological clinic of Children's Hospital of Fudan University. The diagnosis was made according to the criteria of ICD-10. 【Results】 1) The scores of the general visual perception (GVP), the motor-reduced visual perception (MRP), and the visual-motor integration (VMI) of ADHD children were significantly lower than those of healthy children (P<0.05). 2)The scores of the position in space (PS), the visual closure (VC), the eye-hand coordination (EH) of ADHD children were significantly lower than those of healthy children in boys. The scores of the PS, the VC, the form constancy (FC), the EH, the copying (CO), the spatial relations (SR) of ADHD children were significantly lower than those of healthy children in girls. The scores of EH of boys were lower than girls in ADHD children. 3) The VIQ, PIQ, and FIQ of ADHD children were lower than healthy children. 【Conclusions】 There is visual perception development delay or deficient in the children with ADHD. The different characteristics of visual perception development are found between girls and boys. The visual perception should be promoted in the treatment of ADHD children.
