Studies indicate that children with Attention Deficit Hyperactivity Disorder (ADHD) have deficits in social and emotional functions. It can be hypothesized that these children have some deficits in early stages of facial emotion discrimination. Based on this hypothesis, the present study investigated neural correlates of early visual processing during emotional face recognition in this group compared with typically developing children using the Event-Related Potentials (ERPs).
Nineteen boys between the ages of 7 and 11 years diagnosed with ADHD (Combined type) based on DSM-IV-TR classification were compared with 19 typically developing children matched on age and gender. The participants performed an emotional face recognition task while their brain activities were recorded using the event-related potentials procedure.
A significant reduction in the Early Posterior Negativity (EPN) for happy and angry faces has been revealed in ADHD children compared to normal ones (P<0.05).
The present study supports the notion that individuals with ADHD have some impairments in early stage of emotion processing which can leading to their misinterpretation of emotion in faces.
研究表明，患有注意力缺陷多动障碍（ADHD）的儿童在社交和情感功能方面存在缺陷。可以推测，这些儿童在面部情绪识别的早期阶段存在一些缺陷。基于这一假设，本研究使用事件相关电位（ERP），调查了该组儿童与正常发育儿童在情绪面孔识别过程中早期视觉处理的神经相关性。
将19名根据DSM-IV-TR分类诊断为ADHD（混合型）的7至11岁男孩与19名年龄和性别匹配的正常发育儿童进行比较。参与者执行情绪面孔识别任务，同时使用事件相关电位程序记录他们的大脑活动。
与正常儿童相比，ADHD儿童对快乐和愤怒面孔的早期后负波（EPN）显著降低（P<0.05）。
本研究支持这样的观点，即ADHD患者在情绪处理的早期阶段存在一些损伤，这可能导致他们对面部情绪的误解。
