This study explored the early two-word utterances from four Down's syndrome children to determine if they encode the same relational meanings as children developing language normally. Nine semantic categories were established to classify the subject's two-word constructions. Absolute and proportional frequencies of relational types were then used to analyze the relational meanings. The results reveal that this classification system accounts for a combined 79% of the two-word utterances expressed by these Down's subjects. It is suggested that Down's children demonstrate as much diversity in their use of relational meanings as normals at the same linguistic stage. These findings are discussed with respect to what Down's children know about the world as they begin to produce two-word combinations.
本研究探讨了四名唐氏综合征儿童的早期双词话语，以确定他们编码的关系意义是否与正常语言发展的儿童相同。建立了九个语义类别来对受试者的双词结构进行分类。然后使用关系类型的绝对频率和比例频率来分析关系意义。结果表明，该分类系统占这些唐氏受试者所表达双词话语的79%。研究表明，唐氏儿童在关系意义的使用上与处于相同语言阶段的正常儿童一样具有多样性。这些发现结合唐氏儿童在开始产生双词组合时对世界的认知进行了讨论。
