Narratives from three studies differing in subject pools, elicitation procedures, and story content were analyzed using seven variables hypothesized to measure a variety of language abilities used in narrative production. Two questions were addressed: (a) To what extent did multiple variables represent common factors? and (b) To what extent did these variables distinguish children with language disorder from their nondisordered peers? Results indicated that: (a) The seven variables represented two factors; Factor I measured global organization of content (i.e., episode structure), and Factor II measured within- and across-sentence structure (i.e., grammatical sentence structure, within subordinate clause productivity, and textual cohesion), and (b) regardless of study, only the variables representing Factor II were selected as the most effective in predicting group membership.
对来自三项研究的叙述进行了分析,这三项研究在受试者群体、诱导程序和故事内容方面存在差异,使用了七个假设变量来衡量叙事生成中使用的各种语言能力。研究了两个问题:(a)多个变量在多大程度上代表共同因素?(b)这些变量在多大程度上能够区分语言障碍儿童与其无语言障碍的同龄人?结果表明:(a)这七个变量代表两个因素;因素I衡量内容的整体组织(即情节结构),因素II衡量句子内和句子间的结构(即语法句子结构、从属子句内的生成能力和文本衔接);(b)无论研究如何,只有代表因素II的变量被选为预测组成员身份最有效的变量。
