Children with attention deficit hyperactivity disorder (ADHD) are often reported to have deficits of time perception. However, there is a strong relation between performance on tasks of working memory and time perception. Thus, it is possible that the poor performance of children with ADHD on time perception results from their deficit of working memory. In this study, the working memory of participants was separately assessed; therefore, we could explore the relationship between working memory and time perception of children with ADHD. Fifty-six children with ADHD and those of healthy controls completed tasks measuring working memory and time perception. The results showed that the time discrimination ability of children with ADHD was poorer than that of controls. However, there was a strong association between time perception and working memory. After controlling working memory and intelligence, the time discrimination ability of children with ADHD was not significantly poorer than that of controls. We suggest that there is an interdependent relationship between time perception and working memory for children with ADHD.
据报道，患有注意力缺陷多动障碍（ADHD）的儿童往往存在时间感知缺陷。然而，工作记忆任务的表现与时间感知之间存在密切关系。因此，ADHD儿童在时间感知方面表现不佳可能是由于他们的工作记忆缺陷所致。在本研究中，我们分别评估了参与者的工作记忆；因此，我们可以探讨ADHD儿童的工作记忆与时间感知之间的关系。56名ADHD儿童和健康对照组儿童完成了测量工作记忆和时间感知的任务。结果表明，ADHD儿童的时间辨别能力比对照组差。然而，时间感知与工作记忆之间存在密切关联。在控制了工作记忆和智力因素后，ADHD儿童的时间辨别能力并不比对照组显著差。我们认为，ADHD儿童的时间感知和工作记忆之间存在相互依存的关系。
