Discussion
The main fi nding of this study is that scores on a creativity test are the same or higher for children with ADHD when not medicated as when they are medicated. In particular, medicated ADHD
children have a more limited number of responses, indicated by their lower scores on Fluency. As described in previous studies, when medicated, some of the children showed perseveration in reproducing the same sketch (Abraham et al., 2006; Solanto & Wender, 1989; Dyme et al., 1982). Originality was also lower when children with ADHD were taking the drug than when they were not. These results are consistent with the explanation that medicated children experience a greater focusing of attention, as argued by Solanto and Wender (1989), which would prevent using all available environmental stimuli for inspiration. Possibly, as described in Douglas, et al. (1995), when on medication, cognitive tasks involving a single correct solution, like those performed at school, will be favored, but not those involving creative thinking.
