Abstract

Background

Nurturing environments have a critical influence on children's language development. It is unclear to what extent nurturing environments in institutions influence children's language development.

Methods

The present study investigated the early lexical development in Japanese children raised in institutional care (IC) (N = 86; 10–33 months; 37 boys) and compared their lexical skills to a large sample of age peers being raised in biological family care (BFC) (N = 1897; 937 boys) using vocabulary checklists.

Results

Our results present three main findings: (1) Japanese IC children did not exhibit a delay in productive vocabulary compared with BFC children, although their comprehensive vocabulary was delayed; (2) IC children who experienced maltreatment showed poorer vocabulary scores than non-maltreated IC children; (3) both the duration at the institution and the number of books read to them significantly predicted children's vocabulary scores.

Conclusion

Our study suggests that the Japanese institutions included in the present study did not show a negative impact, at least on productive vocabulary, and may competently foster children's language development. We discussed the relationship between institutional environments and children's language development.

在保育院长大的日本儿童的语言发展。

背景：养育环境对儿童的语言发展有着至关重要的影响。目前还不清楚机构中的养育环境在多大程度上影响儿童的语言发展：本研究调查了在机构保育（IC）中长大的日本儿童（人数=86；10-33 个月；37 名男孩）的早期词汇发展情况，并使用词汇检查表将他们的词汇技能与在亲生家庭保育（BFC）中长大的同龄儿童（人数=1897；937 名男孩）进行了大样本比较：我们的研究结果显示了三项主要发现：（1）与亲生家庭保育儿童相比，日本的 IC 儿童在生产性词汇方面没有表现出延迟，尽管他们的综合词汇量有所延迟；（2）与未受虐待的 IC 儿童相比，受过虐待的 IC 儿童的词汇量得分较低；（3）在保育机构的时间长短和为他们朗读的书籍数量都能显著预测儿童的词汇量得分：我们的研究表明，本研究中的日本机构至少对生产性词汇没有负面影响，而且可以有效促进儿童的语言发展。我们讨论了机构环境与儿童语言发展之间的关系。

期刊介绍： Child: care, health and development is an international, peer-reviewed journal which publishes papers dealing with all aspects of the health and development of children and young people. We aim to attract quantitative and qualitative research papers relevant to people from all disciplines working in child health. We welcome studies which examine the effects of social and environmental factors on health and development as well as those dealing with clinical issues, the organization of services and health policy. We particularly encourage the submission of studies related to those who are disadvantaged by physical, developmental, emotional and social problems. The journal also aims to collate important research findings and to provide a forum for discussion of global child health issues.
