The inability to accurately recall sentences has proven to be a clinical marker of specific language impairment (SLI); this task yields moderate-to-high levels of sensitivity and specificity. However, it is not yet known if these results hold for speakers of dialects whose nonmainstream grammatical productions overlap with those that are produced at high rates by children with SLI.
Using matched groups of 70 African American English speakers and 36 Southern White English speakers and dialect-strategic scoring, we examined children's sentence recall abilities as a function of their dialect and clinical status (SLI vs. typically developing [TD]).
For both dialects, the SLI group earned lower sentence recall scores than the TD group with sensitivity and specificity values ranging from .80 to .94, depending on the analysis. Children with SLI, as compared with TD controls, manifested lower levels of verbatim recall, more ungrammatical recalls when the recall was not exact, and higher levels of error on targeted functional categories, especially those marking tense.
When matched groups are examined and dialect-strategic scoring is used, sentence recall yields moderate-to-high levels of diagnostic accuracy to identify SLI within speakers of nonmainstream dialects of English.
无法准确回忆句子已被证明是特定语言障碍(SLI)的一项临床指标;该任务具有中等到较高水平的敏感性和特异性。然而,对于那些非主流语法表现与SLI儿童高频率出现的表现相重叠的方言使用者而言,这些结果是否成立尚不清楚。
我们选取了70名非裔美国英语使用者和36名美国南部白人英语使用者作为匹配组,并采用方言策略评分,研究了儿童的句子回忆能力与其方言及临床状态(SLI与发育正常[TD])之间的关系。
对于两种方言,SLI组的句子回忆得分均低于TD组,根据分析不同,敏感性和特异性值在0.80至0.94之间。与TD对照组相比,SLI儿童逐字回忆水平较低,回忆不准确时出现更多不符合语法的情况,并且在目标功能类别上的错误水平更高,尤其是那些标记时态的类别。
当对匹配组进行研究并采用方言策略评分时,句子回忆在识别非裔美国英语非主流方言使用者中的SLI方面具有中等到较高水平的诊断准确性。
