Event Related Potentials (ERP) were recorded during a two-tone discrimination task in 18 children with Learning Disabilities (LD) and 36 children with Learning Disabilities and Attention Deficit Hyperactivity Disorder (LD-ADHD). Twenty-seven normal children served as a control group. P3 wave amplitude was significantly smaller in the LD and LD-ADHD groups compared with normal children. There was no difference between the LD and LD-ADHD groups. It is suggested that the smaller P3 amplitude in children with LD-ADHD syndromes reflects cognitive and processing difficulties, which frequently coexist with ADHD in these children and is not specifically related to an attention deficit.
在一项双音辨别任务中，对18名学习障碍（LD）儿童、36名患有学习障碍和注意力缺陷多动障碍（LD-ADHD）的儿童记录了事件相关电位（ERP）。27名正常儿童作为对照组。与正常儿童相比，LD组和LD-ADHD组的P3波幅明显较小。LD组和LD-ADHD组之间没有差异。提示患有LD-ADHD综合征儿童的P3波幅较小反映了认知和处理困难，这些困难在这些儿童中常与ADHD共存，且与注意力缺陷没有特异性关系。
