我们报告了一项关于四个正常发展年龄组的儿童（5 - 8岁）和一组8名患有特殊语言障碍（SLI， 5 - 4 - 9岁）的法语儿童的主谓数字一致口语生产的研究。通过实验，要求儿童完成包含一个头名词和一个可能吸引人的“局部名词”的句子序言，从而激发了动词一致性的产生。与以往的研究不同的是，我们研究了局部名词在主语成分（后修饰语）中的吸引力，我们还研究了局部名词在不属于主语成分的结构中的吸引力（插入的附加语）。在正常发育的儿童中，我们报告(1)吸引力效应从早期开始出现；(2)在7岁之前，单数作为默认数字产生；(3)在8岁以后，助词比后修饰语产生更多的错误；5。相比之下，即使是年龄较大的特殊语言障碍儿童也没有表现出吸引力效应，以单数作为默认值的优势，没有句法结构的影响，更普遍的是，持续的高错误率。在7和8之间观察到转折点；5在正常儿童中，以错误率降低和句法结构的显著影响为特征，被解释为协议自动化的指标。从结构因素和工作记忆因素在远距离关系计算中的相互作用角度讨论了句法结构效应。(C) 2003 Elsevier Ltd.版权所有。
We report a study on the spoken production of subject-verb agreement in number by four age groups of normally developing children (between 5 and 8;5) and a group of 8 children with Specific Language Impairment (SLI; between 5;4 and 9;4), all French speaking. The production of verb agreement was experimentally elicited by asking children to complete sentence preambles containing a head noun and a potentially attracting 'local noun'. In contrast to previous studies that focused on attraction with local nouns within the subject constituent (postmodifiers), we also studied attraction with local nouns in structures that are not part of the subject constituent (interpolated adjuncts). In normally developing children, we report that (1) attraction effects appear from early on; (2) singular is produced as the default number until age 7 included; (3) more errors are produced with adjunct structures than with postmodifiers, but only from age 8;5 on. In contrast, even the older SLI children showed no attraction effect, a predominance of the singular as default, no effect of syntactic structure and, more generally, persistent high error rates. The turning point observed between 7 and 8;5 in normal children, characterized by a reduced error rate and a significant effect of syntactic structure, is interpreted as an index of the automatization of agreement. The syntactic structure effect is discussed in terms of the interplay of structural and working memory factors in the computation of long-distance relationships. (C) 2003 Elsevier Ltd.
