To test the proposal that the tense deficit that has been demonstrated for children with specific language impairment (SLI) in other languages is also found in child Spanish and that low performance on tense-related measures can distinguish Spanish-speaking children with SLI from those without.
The authors evaluated evidence from existing spontaneous production, elicited production, and grammaticality judgment studies of finiteness in child Spanish. They measured the relationship of 7 spontaneous speech measures with previous receptive and expressive measures of finiteness and performed a discriminant function analysis, using tense as the target variable, to classify monolingual child Spanish (n = 55) as representing SLI or as typically developing (TD).
Spontaneous speech measures correlated with the results of previous receptive and expressive measures of child Spanish that show a tense deficit. The SLI group was shown to have statistically lower scores than the TD group on 6 of 7 spontaneous speech measures. Multiple discriminant functions, including tense measures by themselves and in combination with spontaneous speech measures, were shown to provide fair to good sensitivity and specificity in the classification of children as having SLI vs. TD.
The findings support the contention that the tense-marking deficit is a plausible clinical marker of SLI for Spanish-speaking children.
检验以下假设，即在其他语言中表现出的特定语言障碍（SLI）儿童的时态缺陷也存在于西班牙语儿童中，并且时态相关测量的低表现可以区分西班牙语 SLI 儿童和非 SLI 儿童。
作者评估了西班牙语儿童中现有关于时态的自发产生、诱发产生和语法判断研究的证据。他们测量了 7 项自发言语测量与先前的西班牙语时态接受性和表达性测量之间的关系，并进行了判别函数分析，以时态为目标变量，将单语西班牙语儿童（n=55）分类为 SLI 或典型发育（TD）。
自发言语测量与西班牙语儿童的先前接受性和表达性测量结果相关，这些结果表明存在时态缺陷。与 TD 组相比，SLI 组在 7 项自发言语测量中的 6 项上的得分明显更低。包括时态测量本身以及与自发言语测量相结合的多个判别函数，在将儿童分类为 SLI 与 TD 方面表现出了较好的敏感性和特异性。
这些发现支持了这样一种观点，即时态标记缺陷是西班牙语儿童 SLI 的一个合理的临床标记。
