ABSTRACT

This research was funded through the American Speech and Hearing Foundation’s 2012 StudentResearch Grant in Early Childhood Language Development awarded to Vanessa Harwood as well as an anonymous generous donation to Haskins Laboratories. Electrophysiological measures of language within early childhood provide important information about neurolinguistic development. We investigated associations between amplitude and latency of the P1 and N2 event-related potential components in response to spoken pseudowords, and clinical measures of language performance within a sample of 58 typically developing children between 24 and 48 months. N2 amplitude differences between repeated and new tokens were correlated with measures of expressive and receptive language and speech sound production. Phonemic sensitivity measured by the N2 component may reflect the integrity of neural networks that are important for speech perception and production in young children.

摘要

这项研究由美国言语和听力基金会 2012 年授予瓦妮莎·哈伍德 (Vanessa Harwood) 的儿童早期语言发展学生研究补助金以及向哈斯金斯实验室 (Haskins Laboratories) 的匿名慷慨捐款资助。幼儿时期语言的电生理测量提供了有关神经语言发展的重要信息。我们调查了 P1 和 N2 事件相关电位成分对口语伪词反应的振幅和潜伏期之间的关联，以及 58 名 24 至 48 个月之间典型发育儿童样本中语言表现的临床测量。重复和新标记之间的 N2 幅度差异与表达性和接受性语言以及语音产生的测量相关。N2 分量测量的音素敏感性可能反映了神经网络的完整性，这对于幼儿的言语感知和产生很重要。
