ACQUISITION OF LANGUAGE IN DIFFERENT SOCIAL CONTEXTS

人们普遍认为，儿童早期发展对儿童的年龄、性别、年龄、性别和年龄的变化很敏感。 它发生的社会环境，虽然细节， 环境与儿童发展的关系不好 明白 这项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 以及早期语言经验对儿童语言的影响 发展 参与者将是30名工人阶级和30名中上层阶级的母亲 和他们16-22个月大的孩子。 互动将记录在 在四个不同的自然环境中的家--穿衣，喂食， 读书和玩耍 母婴互动的录像记录 将在两个月的语言增长期内收集两次， 包括组合语音的开始。 母亲的财产和 从这些互动的转录本编码的儿童语音将提供 两项拟议研究的数据。 研究1调查了母亲对孩子的讲话是否随着年龄的增长而变化。 背景或社会阶层的功能，以及这种变化是否相关 孩子的语言成长。 研究2调查是否不同 环境以不同的方式支持语言开发， 母亲言语对儿童语言发展的影响 两个社会阶层。 本研究的目的是描述语言的范围， 儿童在不同社会环境中的互动， 这些环境对语言发展的影响。 该描述 应该为评估竞争性假设提供基础， 儿童的学习机制使用儿童的经验提供的 社会环境对语言习得的影响 这项研究还应 为优化语言环境支持提供依据 在语言延迟的情况下获得。

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.
