Abstract

The visual perception is completely associated with successful performance of motor skills. Development of Children’s perceptual abilities considerably improved motor function or weakens. So awareness of the developmental status of visual perception is essential. The purpose of this study was to compare depth perception of 7-9 years old children Characterized by developmental coordination disorder (DCD) with healthy children. Participants were 80 male subjects, 40 subjects with developmental coordination disorder and 40 healthy peers that selected on available sampling. All have normal vision or were modified. Depth perception of subjects was evaluated in three times by the depth perception model D9009. The average error of depth perception was used as the depth perception score. Independent T-test results showed significant difference between healthy children and DCD.The average error in thehealthy children was significantly lower (MD =9.45). From the results can be concluded that weaker motor functions and motor delay and consequently the DCD has negative impact on the visual perception of depth. Therefore, in dealing with these people due to the importance of depth perception in motor function, attention to this matter is essential.
