ACQUISITION OF LANGUAGE IN DIFFERENT SOCIAL CONTEXTS

人们普遍认为，儿童早期发展对 它发生的社会环境，尽管 环境与儿童发展的关系不是很好 明白了。建议的研究是一项短期的纵向研究 社会环境对早期母婴对话的影响 以及早期语言体验对儿童语言的影响 发展。 参与者将是30名工薪阶层和30名中上阶层的母亲 以及他们16到22个月大的孩子。互动将记录在 在四个不同的自然主义环境中的家--穿衣，喂食， 读书，玩耍。记录母子互动的录像带 将在两个月的语言增长期间收集两次 包括组合语音的开头。母亲和母亲的财产 从这些互动的转录文本编码的儿童语音将提供 两项拟议研究的数据。 第一项研究调查了母亲对孩子的讲话是否随着 设定或社会阶级的作用以及这种变化是否相关 对孩子的语言成长有很大的帮助。研究2调查了不同的 环境通过比较以不同的方式支持语言发展 母亲的言语对儿童语言发育的影响 两个社会阶层。 这项研究的目的是描述语言学的范围 儿童在不同社会环境中体验的互动和 这些环境对语言发展的影响。这一描述 应该为评估相互竞争的假说提供基础 儿童的学习机制使用儿童提供的经验 语言习得中的社会环境。这项研究也应该 为优化语言环境支撑提供依据 语言延迟情况下的习得。

It is widely acknowledged that early child development is sensitive to the social environment in which it occurs, although the details of the relationship between the environment and child development are not well understood. The proposed research is a short-term longitudinal study of the influence of the social environment on early mother-child conversation and the effects of that early language experience on children's language development. The participants will be 30 working-class and 30 upper-middle-class mothers and their 16-22 month-old children. Interaction will be recorded in the home in four different naturalistic settings -- dressing, feeding, bookreading, and play. Video-taped records of mother-child interaction will be collected twice over a two-month period of language growth which includes the beginning of combinatorial speech. Properties of mother and child speech coded from transcripts of these interactions will provide the data for two proposed studies. Study 1 investigates whether mothers' speech to their children varies as a function of setting or social class and whether such variation is relevant to children's language growth. Study 2 investigates whether different environments support language development in different ways by comparing the influences of mothers' speech on their children's language growth in the two social classes. The objective of this research is to describe the range of linguistic interactions children experience in different social environments and the influences of those environments on language development. That description should provide a basis for evaluating competing hypotheses concerning how the child's learning mechanisms use the experiences provided by the child's social environment in acquiring language. This research should also provide a basis for optimizing the environmental supports for language acquisition in cases of language delay.
