This study compared the use of English past tense in a group of Spanish-English bilingual children with language impairment (BLI) to younger groups of bilinguals with typical and atypical language development reported in an earlier study. Ten children with BLI enrolled in 3rd-6th grade participated. Children supplied 12 regular, 12 irregular, and 12 novel past tense verbs on an elicitation task. The results demonstrated that despite 2.5 years of school exposure, older children with BLI still lagged in the production of regular and novel past tense verbs when compared to the younger typically developing (TD) controls. Although the rates of productive errors on irregular verbs increased, the older students nonetheless failed to achieve rates of over-regularization comparable to the younger TD group. These data extend earlier findings regarding the exceptional challenge of past tense use, particularly with respect to finite verb morphology in certain children with BLI. These challenges, combined with similarities between monolingual and bilingual impairment, are largely compatible with a linguistic deficit account.
本研究将一组有语言障碍（BLI）的西班牙裔-英语双语儿童使用英语过去时的情况，与早期研究中报告的具有典型和非典型语言发展的较年轻双语儿童组进行了比较。十名就读于三至六年级的BLI儿童参与了研究。儿童在一项诱发任务中提供了12个规则、12个不规则和12个新颖的过去时动词。结果表明，尽管有2.5年的学校学习经历，但与年龄较小的发育正常（TD）对照组相比，年龄较大的BLI儿童在规则和新颖过去时动词的产出方面仍然滞后。尽管不规则动词的产出错误率有所增加，但年龄较大的学生仍未达到与年龄较小的TD组相当的过度规则化率。这些数据扩展了早期关于过去时使用的特殊挑战的研究结果，特别是在某些BLI儿童的限定动词形态方面。这些挑战，再加上单语和双语障碍之间的相似性，在很大程度上与语言缺陷理论相符。
