Differentiating between typically and atypically developing child populations: A microanalysis of the children's Draw-a-Clock test
The Children's Draw a Clock Test (CDCT) was used in this study to compare differences in typically developing (TD) and atypically developing children's (ATD) performance. The participants (N = 160) were given the CDCT in group or individual administrations. Examination of developmental trends, using ANOVA, and MANOVA, indicated that both TD and ATD children's performance improves across most age groups, except from age group 8–9.99 to 10–11.99. Analysis of the performance of TD children and children diagnosed with ADHD, RD, and ADHD+RD revealed that there are significant differences in performance across the diagnostic groups. TD children performed significantly better than ATD children on both conceptual knowledge and spatial planning. TD children also performed better on measures of conceptual knowledge than children diagnosed with RD. TD children and children diagnosed with RD did better on spatial planning than children diagnosed with ADHD. These last two findings were not replicated when the analysis was run again with a smaller sample of equal cell sizes. Contrary to the hypotheses put forth in this study, the children's performance did not vary on measures of self-monitoring and sequencing errors. Additionally, the hypotheses relating to the co-morbid group (ADHD+RD) were not supported. ^
