Abstract: Objective To determine cognitive function domains of temporal processing,the possible etiopathogenisis,and to supply scientific evidence for intervention of attention deficit hyperactivity disorder (ADHD)children. Methods One hundred children with ADHD and 100 healthy controls matched in age,gender,grade,handedness were measured with neuropsychological tests concerning the domain of temporal processing (i.e,time production).The performances were compared using repeated measurement of multivariate analysis of variance (MANOVA) and MANCOVA with FIQ controlled between two groups. Results The omnibus MANOVA had group and duration main effects and interaction effect in time production task,the absolute discrepancies,the accuracy coefficients were significant different.The results showed that the abosulte discrepancyies were greater and the accuracy coefficients were less in children with ADHD than those in healthy controls.The performance in both groups became worse with the time duration increasing,but much worse in children with ADHD.The results remained unchanged after controlling for FIQ.The ACOVAs of each duration showed that children with ADHD performed worse than healthy controls in the long durations. Conclusion Temporal processing deficiency may be inherent and not stem from other cognitive deficiencies.
