This study examines the lexical characteristics of language development of 17 children between 24 and 41 months of age with a history of slow expressive language acquisition (experimental group). The purpose of the investigation is to compare these subjects to 49 children (ranging in age from 13-24 months) with a normal language history matched for vocabulary size to determine, whether the expressive vocabulary of children with language delay is same to normal group. The data were collected using the parental report instrument "Il Primo Vocabolario del Bambino"(Caselli and casadio 1995) the Italian version of MacArthur Communicative Development Inventories (Fenson et al. 1993). For analyses of word production, children were divided into four groups based on their total vocabulary size: 1) 11 to 20 words; 2) 21 to 50 words; 3) 51 to 100 words; 4) 101 to 200 words. Analysis revealed a significant difference in verbs and grammatical function words when the level of vocabulary size of experimental group was between 21 and 50 words. In the other vocabulary size there were not significant differences. In summary the results of this study show that the vocabulary composition of children with slow expressive language acquisition is same that of children 14-16 months younger.
本研究调查了17名年龄在24至41个月之间、有表达性语言习得迟缓病史的儿童（实验组）的语言发展词汇特征。调查目的是将这些受试者与49名年龄在13至24个月之间、有正常语言史且词汇量匹配的儿童进行比较，以确定语言迟缓儿童的表达性词汇量是否与正常组相同。数据收集使用家长报告工具《儿童第一本词汇表》（卡塞利和卡萨迪奥，1995年），即麦克阿瑟沟通发展量表（芬森等人，1993年）的意大利语版本。为了分析单词产出情况，根据儿童的总词汇量将其分为四组：1）11至20个单词；2）21至50个单词；3）51至100个单词；4）101至200个单词。分析显示，当实验组词汇量水平在21至50个单词之间时，动词和语法功能词存在显著差异。在其他词汇量水平上则没有显著差异。总之，本研究结果表明，表达性语言习得迟缓儿童的词汇构成与小14至16个月的儿童相同。
