Abstract: Objective To explore the influence of domestic dialect on language development of children, thus to provide theoretical reference for discussing the reasons for developmental language disorder. Methods Totally 688 children aged 35.1—95.7 months in Department of Developmental and Behavioral Pediatrics, Shanghai Children's Medical Center from November 2015 to September 2019, were enrolled in this study.According to their language exposure in family, 151 children were selected as mandarin group and 537 children were in dialect group.Chi-square test and Mann-Whitney U test were run to examine the differences on language abilities between two groups. Results There were no significant differences on age, gender composition and the proportion of developmental language disorder between mandarin group and dialect group (P>0.05).Moreover, difference was not found on five dimensions of language abilities between children with and without developmental language disorder, including total language, receptive, expressive, semantic and syntax (P >0.05). Conclusions Domestic dialect has no adverse effect on children's language development.On the contrary, the quality and quantity of language exposure is more important for early language development.

摘要： 目的 探究家庭方言环境对儿童语言发育的影响, 为探讨儿童语言障碍原因提供理论依据。方法 收集2015年11月-2019年9月于上海儿童医学中心发育行为儿科就诊并完成语言能力测试的儿童资料。共688名儿童, 年龄范围35.1~95.7个月;根据家庭方言环境分为普通话组(n=151), 方言组(n=537)。采用χ²检验和Mann-Whitney U检验分析两组儿童的语言能力差异。结果 普通话组和方言组儿童的年龄、性别构成以及语言障碍比例, 差异无统计学意义(P>0.05);语言正常和障碍儿童在整体语言、听力理解、语言表达、语义、句法5个维度上均不受方言环境影响(P>0.05)。结论 家庭方言环境不是儿童语言发育的危险因素, 语言暴露的质量与数量对儿童早期发展更为重要。
