这项研究考察了有和没有特定语言障碍(SLI)儿童的过去时标记的生产力和表征。参与者包括11名患有SLI的6岁儿童、11名年龄匹配的对照组和11名MLU匹配的对照组。规则动词和不规则动词被用来检验规则标记的生产力。过去时的表征是通过要求儿童改变同音对的同音和不规则的根动词来检验的。这三组受试者都表现出了对过去时态的有效标记，尽管如预期的那样，受损组的准确度低于早期控制组。在SLI和MLU匹配组中，过去时标记的模式随着单词的语音成分和词形变化频率的变化而变化，并且所有儿童都呈现出对语法结构敏感的过去时系统。这些发现重复了先前对SLI形态系统的研究，并提供了这些儿童形态优势和劣势的额外说明。优势包括儿童对词汇的语法和语音特征的敏感性；劣势包括常规过去时标记的生产力有限，以及与正常发育儿童相比对频率操纵的更敏感。根据SLI剖面的性质对结果进行讨论。它们也被用来评估作为研究基础的理论模型。
This study examined the productivity and representation of past-tense marking in children with and without specific language impairment (SLI). Participants were 11 6-year-olds with SLI, 11 age-matched controls, and 11 MLU-matched controls. Regular and irregular verbs were used to examine the productivity of regular marking. Past-tense representation was examined by asking children to inflect homophonous pairs of denominal and irregular root verbs. All three groups demonstrated productive marking of past tense, although as expected the accuracy of the impaired groups was less than that of earlier control group. Patterns of past-tense marking as a function of a word's phonological composition and inflectional frequency were the same for the SLI- and MLU-matched groups, and all children presented a past-tense system that was sensitive to grammatical structure. The findings replicate previous research of the SLI morphological system and provide additional specification of these children's morphological strengths and weaknesses. Strengths include the children's sensitivity to grammatical and phonological characteristics of the lexicon; weaknesses include limited productivity of regular past-tense marking and a greater sensitivity to frequency manipulations as compared to normally developing children. Results are discussed in terms of the nature of the SLI profile. They also are used to evaluate the theoretical model on which the study was based.
