Abstract
The purpose of the current study was to examine the performance of children with and without ADHD in time reproduction tasks involving varying durations and modalities. Method: Fifteen ADHD children, diagnosed by a pediatric psychiatric with my diagnosis confirmation using ADHD rating scale and Conner’s parents rating scale, selected from a psychiatric clinic patients and 15 healthy controls selected from two private schools, completed time reproduction tasks in three modalities (auditory, visual, and a unique combined auditory/visual condition) and six durations (6 second, 12 seconds, 18 seconds, 24 seconds, 36 seconds, and 48 seconds).Results: Consistent with our predictions, we found main effects of group (participants with ADHD were significantly less accurate than those without ADHD) and duration (accuracy decreased as temporal duration increased. But main effects of modality (in which responses in the combined conditions should be more accurate than those in the auditory condition, which in turn should be more accurate than those in the visual condition) were not found. Furthermore, predicted interactions between group and duration (the discrepancy in performance between the two groups grew as temporal duration increased) were supported. But, interactions between group and modality (in which the modality effect should be greater for participants with ADHD) were not supported. A marginal, nonsignificant interaction between group, modality, and duration was also found.
