This paper focuses on the aspects of the lexicon in 66 prematurely born very-low-birth-weight and 87 full-term Finnish children at 2;0, studied using the Finnish version of the MacArthur Communicative Developmental Inventory. The groups did not differ in vocabulary size. Furthermore, the female advantage in vocabulary size was not seen in preterm children. The overall shapes of the trajectories for the main lexical categories as a function of vocabulary size were highly similar in both groups and followed those described in the literature. However, there were significant differences in the percentage of nouns and grammatical function words between the two groups. The results suggest that prematurity 'cuts off' the female advantage in vocabulary development. Furthermore, it also seems that there are differences between prematurely born and full-term children in the composition of the lexicon at 2;0. The findings support the universal sequence in the development of lexical categories.
本文聚焦于66名早产极低出生体重芬兰儿童和87名2岁足月儿的词汇方面，使用芬兰语版的麦克阿瑟沟通发展量表进行研究。两组在词汇量上没有差异。此外，早产儿童中未出现女性在词汇量上的优势。两组中主要词汇类别的轨迹总体形状与词汇量的函数关系高度相似，且与文献中描述的一致。然而，两组之间名词和语法功能词的百分比存在显著差异。结果表明，早产“切断”了女性在词汇发展方面的优势。此外，2岁时，早产儿童和足月儿在词汇构成上似乎也存在差异。这些发现支持了词汇类别发展的普遍顺序。
