Previous studies have shown that children with cochlear implants have difficulty in grammar acquisition. Vocabulary acquisition and grammar abilities are important during language development. The purpose of this study was to investigate the effect of grammar therapy on the lexical ability of cochlear implanted children. Five children with cochlear implants and grammatical problems were treated using a grammar task designed for the current study. Before and after the treatment, repeated evaluations were performed using the Mean Length of Utterance (MLU) and Persian Developmental Sentence Scoring (PDSS) indices for grammar and NDW and NTW indices for vocabulary abilities; these show the number of different words and the number of total words respectively. Grammar intervention was successful in cochlear implanted children of the present study. In addition, treatment of grammatical problems increased the lexical ability of all children; NDW and NTW scores increased, which was confirmed by the effect size indices. In the follow-up phase, the cochlear implanted children were able to maintain the increase in NTW and NDW values. Improving grammar skills in cochlear implanted children also increased their lexical ability. Therefore, grammar therapy helps to increase the vocabulary of children too.
先前的研究表明，接受人工耳蜗植入的儿童在语法习得方面存在困难。词汇习得和语法能力在语言发展过程中很重要。本研究的目的是调查语法治疗对人工耳蜗植入儿童词汇能力的影响。五名有语法问题的人工耳蜗植入儿童接受了为本研究设计的语法任务治疗。在治疗前后，使用话语平均长度（MLU）和波斯语发展句子评分（PDSS）指数评估语法，使用不同单词数（NDW）和总单词数（NTW）指数评估词汇能力；这些指数分别显示不同单词的数量和总单词的数量。本研究中，语法干预对人工耳蜗植入儿童是成功的。此外，语法问题的治疗提高了所有儿童的词汇能力；NDW和NTW分数增加，效应大小指数证实了这一点。在随访阶段，人工耳蜗植入儿童能够维持NTW和NDW值的增加。提高人工耳蜗植入儿童的语法技能也提高了他们的词汇能力。因此，语法治疗也有助于增加儿童的词汇量。
