Brainstem, middle-latency, and long-latency auditory evoked potentials (BAEPs, MAEPs, and LAEPs) and visual evoked potentials (VEPs) were recorded from subjects without mental retardation (control subjects) and from subjects with organic mental retardation or cultural-familial mental retardation. Both mentally retarded groups had smaller mean VEP amplitudes and longer mean LAEP latencies in response to target stimuli than did the control subjects, showing that the target stimuli were evaluated more slowly by the subjects with than by those without mental retardation. We found no significant differences between the mentally retarded and control groups with regard to BAEPs or MAEPs, and the two mentally retarded groups did not differ significantly in any EP parameter. The implications of these results for the defect and developmental theories of mental retardation were discussed.
对无智力障碍的受试者（对照组）以及患有器质性智力障碍或文化 - 家族性智力障碍的受试者记录了脑干听觉诱发电位（BAEP）、中潜伏期听觉诱发电位（MAEP）和长潜伏期听觉诱发电位（LAEP）以及视觉诱发电位（VEP）。与对照组相比，两个智力障碍组在对目标刺激的反应中，平均VEP波幅较小，平均LAEP潜伏期较长，这表明与无智力障碍的受试者相比，有智力障碍的受试者对目标刺激的评估更为缓慢。我们发现，在BAEP或MAEP方面，智力障碍组与对照组之间没有显著差异，并且两个智力障碍组在任何诱发电位参数上也没有显著差异。讨论了这些结果对智力障碍的缺陷和发展理论的意义。
