The present study applied the dimensional approach to test whether self-reported symptoms of Attention Deficit/Hyperactivity Disorder (ADHD) in adults are associated with the speed of interhemispheric interaction. A sample of first grade students (N = 112) completed Conners' Adult ADHD Rating Scales and letter matching reaction time tasks. In the tasks, participants had to match a single target letter displayed below the fixation cross, either on left or right visual field, with one of two letters displayed above the fixation cross, one letter on each visual field. For each task, identical letters were presented either within the same visual field (within hemisphere condition) or across visual fields (across hemisphere condition). Interhemispheric interaction was indexed as the difference in mean reaction time between within and across hemisphere conditions. Comorbid problems such as depression, anxiety, and stress may affect task performance and are controlled for in this study. Findings indicated that self-reported ADHD symptomology, especially hyperactivity, in the presence of stress was weakly but significantly associated with fast interhemispheric interaction.
本研究采用维度方法来检验成人注意力缺陷/多动障碍（ADHD）的自我报告症状是否与半球间相互作用的速度相关。一年级学生样本（N = 112）完成了康纳斯成人ADHD评定量表和字母匹配反应时任务。在任务中，参与者必须将显示在注视十字下方、位于左或右视野的单个目标字母与显示在注视十字上方的两个字母之一进行匹配，每个视野一个字母。对于每个任务，相同字母要么在同一视野内呈现（半球内条件），要么跨视野呈现（半球间条件）。半球间相互作用以半球内和半球间条件下平均反应时的差异为指标。诸如抑郁、焦虑和压力等共病问题可能会影响任务表现，本研究对此进行了控制。研究结果表明，在存在压力的情况下，自我报告的ADHD症状，尤其是多动，与快速的半球间相互作用存在微弱但显著的关联。
