• The WISC-IV provides a detailed account of the cognitive profile of children with DCD.
• The DCD group, overall, present with weaknesses in processing speed and working memory.
• Within-group analyses depict a heterogeneous cognitive profile in the DCD group.
• Motor demands in the WISC-IV PSI are a potential confound, but performance in this area may highlight the need for further exploration of motor difficulties.
• The DCD group cannot be differentiated from their peers solely on a cognitive profile.
BackgroundWhile primarily a motor disorder, research considering the cognitive abilities in children with Developmental Coordination Disorder (DCD) is limited; even though these children often struggle academically.AimsThe present study aimed to characterise the IQ profile of children with and without DCD, and to identify whether children with DCD exhibit specific cognitive weaknesses.Methods and procedures104 children participated in the study. Fifty-two children (mean age, 9 years) with a diagnosis of DCD were matched to 52 typically-developing children by age and gender. Cognitive ability was assessed using the Wechsler Intelligence Scale for Children (WISC-IV).Outcomes and resultsChildren with DCD performed poorer than their peers on processing speed and working memory measures. Individual analyses revealed varied performance in the DCD group across all cognitive indices, despite displaying Full-Scale IQs in the typical range. Discriminant function analyses show processing speed and working memory performance predicted only 23% of between-group variability.ConclusionsChildren with DCD present with a heterogeneous cognitive profile, lending support to individual case analyses in research and when designing educational assistance plans. The motorically-demanding nature of the WISC-IV processing speed tasks raises specific concerns about using this index of the IQ assessment in this population. Research and practical implications are raised.
