LANGUAGE DEVELOPMENT IN DOWN SYNDROME CHILDREN

描述：（根据申请人的描述改编） 研究是研究语言的短期微观发生过程 唐氏综合征青少年的习得、理解和使用。 的 这项研究源于一个理论框架（儿童谈话模型）， 强调了语境中的先前历史在使 语言可用，听觉短期记忆减弱的历史 唐氏综合症儿童的缺陷。 实验的目的是（1） 评估听觉短期记忆支持的作用，并检查 句子重复在新单词的附带学习和定性 句子理解策略的转换;（2）话语检查 面试形式中的公式化、话轮转换和潜伏模式; (3)评估话语模型对有效干预的预测， 在独特的共现语境中学习多个新名词和动词; 通过重复和扩展获得新的话语结构 在获得后的微观遗传学研究中促进讲故事 在五到六次会议上。

DESCRIPTION: (Adapted from applicant's description) The purpose of this research is to study short-term, microgenetic processes of language acquisition, comprehension, and usage in teenagers with Down syndrome. The study derives from a theoretical framework (the Child Talk model) that emphasizes the role that prior history of talk in context plays in making language available, a history attenuated by auditory short-term memory deficits in children with Down syndrome. Experiments are proposed to (1) evaluate the role of auditory short-term memory support and to examine sentence repetition in incidental learning of novel words and in qualitative shifts in sentence comprehension strategies; (2) examine utterance formulation, turn-taking, and latency patterns in an interview format; (3) assess the discourse model s prediction of effective interventions for learning of multiple new nouns and verbs in distinctive co-occurring contexts; and acquisition of new discourse structures through repeated and expanded prompting of story telling in microgenetic studies that follow acquisition across five or six sessions.
