Introduction: Developmental Coordination Disorder (DCD) is one of the conspicuous deficiencies in the area of motor skill development in children, and at first glance it shows itself as a problem in the field of learning or in possessing skills that require motor coordination. Thus, the aim of this study was to compare the perception and visual memory of children with and without DCD in the city of Sanandaj.
Methodology: The method employed for this research is post-event correlation and the study sample included 20 children with DCD and 20 children without DCD aged 7 to 11 years who were selected among students of District 2 in Sanandaj by multistage cluster sampling. Frastyg test is used to measure visual perception while visual memory has been measured by Andre Rey test. Data were analyzed through independent t-test and by using SPSS software version 22.
Results: In order to determine the significance of the difference between mean scores, independent t-test was employed. Having met the assumption of homogeneity of variances in visual perception variable and visual memory variable, we observed that there was a significant difference between, first, visual perception mean score of the two groups of children with and without DCD and, second, between visual memory mean score of the two groups of children with and without DCD.
Discussion: Research findings revealed that scores on visual perception and visual memory in children without DCD are higher than those in the children with DCD; therefore, this study underscores the importance of considering the characteristics of visual perception and visual memory in children with developmental coordination disorder in designing or developing therapeutic and educational interventions.
