特定语言障碍（SLI），就像许多复杂行为状况的诊断标签一样，通常被认为是定义一类儿童，这些儿童不仅在程度上而且在种类上与正常发展语言的儿童不同。尽管这一假设对理论模型和临床方法具有重要意义，但其有效性尚未得到检验。在这项研究中，使用称为“平均以上减去低于削减”的分类程序对 3 岁（N = 620）和 4 岁（N = 623）儿童的语言分数分布进行了分析（MAMBAC；P. E. Meehl & L. J. Yonce，1994）。语言分数在两个年龄段均按维度分布，未能支持 SLI 儿童对应的定性不同群体的假设。
Specific language impairment (SLI), like many diagnostic labels for complex behavioral conditions, is often assumed to define a category of children who differ not only in degree but also in kind from children developing language normally. Although this assumption has important implications for theoretical models and clinical approaches, its validity has not been tested. In this study, distributions of language scores from children at ages 3 (N = 620) and 4 (N = 623) years were analyzed using a taxometric procedure known as "mean above minus below a cut" (MAMBAC; P. E. Meehl & L. J. Yonce, 1994). Language scores were distributed dimensionally at both ages, failing to support the hypothesis of a qualitatively distinct group corresponding to children with SLI.
