EVOKED POTENTIALS TO FUNCTION WORDS IN SLI CHILDREN

描述：这项研究的目的是确定儿童是否 患有系统性红斑狼疮和发育正常的儿童在敏感性方面相似 关于虚词的声学-语音特性，因为它们依赖于 虚词在故事理解和神经生理学中的作用 虚词知觉的相关因素。这些问题的答案如下 旨在梳理和/或澄清不同版本的知觉 SLI的加工理论。 40名患有系统性红斑狼疮的学龄前儿童和40名年龄匹配的对照组 补充两项研究，这两项研究涉及聆听听讲的故事。 当儿童加工虚词和废话时，事件相关电位将被记录下来 故事中嵌入的音节。两者之间的唯一区别是 故事是正常虚词和故事的声学属性 无意义的音节。在听取了每个故事的部分内容后，参与者将 指向一幅代表故事中人物所见的图片。之后 听故事，参与者将完成一个基本的听觉 辨别任务。

DESCRIPTION: The purpose of this study is to determine whether children with SLI and normally-developing children are similar in their sensitivity to the acoustic-phonetic properties of function words, in their reliance on function words in story comprehension, and in the neurophysiological correlates of function word perception. Answers to these questions are designed to tease apart and/or clarify different versions of perceptual processing theories of SLI. Forty preschool-aged children with SLI and 40 age-matched controls will comple two studies that involve listening to stories presented auditorally. ERPs wil be recorded as the children process function words and nonsense syllables that are embedded in stories. The only differences between the stories are the acoustic properties of the normal function words and the nonsense syllables. After hearing sections of each story, participants will point to a picture tha represents what a character in the story saw. After listening to the stories, participants will complete a basic auditory discrimination task.
