关于患有注意力缺陷多动障碍（ADHD）的儿童在多任务处理方面有增加的困难，有相当多的讨论，但很少有实验数据。在本研究中，我们使用心理不应期（PRP）效应来研究两个刺激反应任务的同时加工。我们假设患有多动症的儿童会表现出更大的PRP效应，这表明在刺激-反应处理中存在一个长期的“瓶颈”。与25名对照儿童相比，共有19名患有多动症的学龄儿童表现出了持久的PRP效应，这表明多动症患者在多任务处理方面的认知成本更高。
There is considerable lay discussion that children with attention deficit hyperactivity disorder (ADHD) have increased difficulty with multitasking, but there are few experimental data. In the current study, we examine the simultaneous processing of two stimulus-response tasks using the Psychological Refractory Period (PRP) effect. We hypothesized that children with ADHD would show a greater PRP effect, suggesting a prolonged "bottleneck" in stimulus-response processing. A total of 19 school-aged children with ADHD showed a prolonged PRP effect compared with 25 control children, suggesting a higher cognitive cost in ADHD for multitasking.
