Thirty-eight severely dyslexic boys and 38 good readers were evaluated with neurometrics, a diagnostic procedure based on the application of numerical taxonomy to EEG spectra obtained during resting conditions, supplemented by selected evoked potential features. This procedure generates deviance scores for the EEG spectra by comparing each individual's values to those obtained from a normative population and has been reported to discriminate learning disabled children from normal controls (Ahn et al. 1980). In the present study, all subjects, dyslexic and control, passed stringent screening to assure normal intellectual, neurological, sensory and emotional status. The false positive rate obtained in our control group was comparable to that reported earlier. However, none of the deviance scores significantly discriminated dyslexics from controls; most subjects from both groups were classified as normal. Severe dyslexia per se is thus not associated with the specific neurometric abnormalities reported previously in more heterogeneous learning disabled populations.
38名严重诵读困难男孩和38名优秀阅读者接受了神经测量学评估，这是一种诊断程序，基于将数值分类法应用于静息状态下获得的脑电图频谱，并辅以选定的诱发电位特征。该程序通过将每个个体的值与从正常人群中获得的值进行比较来生成脑电图频谱的偏差分数，并且据报道可以区分学习障碍儿童和正常对照组（安等人，1980年）。在本研究中，所有受试者，无论是诵读困难组还是对照组，都通过了严格的筛查，以确保智力、神经、感官和情绪状态正常。我们对照组中获得的假阳性率与之前报道的相当。然而，没有一个偏差分数能够显著区分诵读困难者和对照组；两组中的大多数受试者都被归类为正常。因此，严重诵读困难本身与之前在更多异质性学习障碍人群中报道的特定神经测量异常无关。
