There are very few studies, and at present none in Spanish, on vocabulary composition in children with Down syndrome (DS). Nor has the topic been widely assessed in Spanish-speaking children with typical development (TD). This study analyzed the composition of early vocabularies in a large sample of Spanish-speaking children with DS and compared it with that of children with TD.
We studied 108 children with DS and 108 children with TD with mental ages between 8 and 29 months, matched for size of productive vocabulary and gender. The MacArthur-Bates Communicative Development Inventories (Fenson et al., 1993, 2007), adapted to the language development profile of children with DS, were used. The categories examined were nouns, predicates, closed-class words, and social words.
The performance of children with DS was similar to that of children with TD with the same vocabulary size. The only significant difference was the larger production of nouns by children with DS. The trends of development in the different classes of words were also similar.
The strategies used by children with DS to learn vocabulary may be similar to those used by children with TD in the first stages of language learning.
关于唐氏综合征（DS）患儿的词汇构成，研究极少，目前尚无西班牙语研究。在西班牙语环境中发育正常（TD）的儿童中，该主题也未得到广泛评估。本研究分析了大量讲西班牙语的DS患儿早期词汇的构成，并将其与TD患儿的词汇构成进行比较。
我们研究了108名DS患儿和108名TD患儿，他们的心理年龄在8至29个月之间，根据产出性词汇量和性别进行匹配。使用了根据DS患儿语言发展特点改编的麦克阿瑟-贝茨交流发展量表（Fenson等人，1993年，2007年）。所考察的类别包括名词、谓语、封闭类词和社交词汇。
词汇量相同的情况下，DS患儿的表现与TD患儿相似。唯一显著的差异是DS患儿产出的名词更多。不同类别词汇的发展趋势也相似。
DS患儿学习词汇所采用的策略可能与TD患儿在语言学习第一阶段所采用的策略相似。
