Abstract

Speech perception skills have been implicated in the development of phoneme-graphene correspondence, yet the exact nature of speech perception and word reading ability remains unknown. We investigate phonological sensitivity to native (English) and nonnative (Spanish) speech syllables within an auditory oddball paradigm using event related potentials (ERPs) collected from lateral temporal electrode sites in 33 monolingual English-speaking children aged 6–8 years (N = 33). We further explore the relationship between ERPs to English word reading abilities for this group. Results revealed that language stimuli (English, Spanish), ERP condition (standard, deviant), and hemisphere (left, right) all influenced the lateral N1 component. ERPs recorded from deviant English stimuli were significantly more negative within the left hemisphere compared to all other recorded ERPs. Mean amplitude differences within the N1 in left lateral electrode sites recorded in response to English phoneme contrasts significantly predicted English word reading abilities within this sample. Results indicate that speech perception of native contrasts recorded in left temporal electrode sites for the N1 component are linked to English word reading abilities in early school-aged children.

事件相关电位与母语语言对比预测早期学龄儿童的单词阅读能力

语音感知技能与音素-石墨烯对应的发展有关，但语音感知和单词阅读能力的确切性质尚不清楚。我们利用从33名6-8岁的单语英语儿童(N = 33)的颞侧电极处收集的事件相关电位(ERPs)，研究了在听觉怪异范式下对母语(英语)和非母语(西班牙语)语音音节的语音敏感性。我们进一步探讨erp与该群体英语单词阅读能力之间的关系。结果表明，语言刺激(英语、西班牙语)、ERP条件(标准、偏差)和脑半球(左、右)均影响侧侧N1成分。与所有其他记录的erp相比，偏离英语刺激记录的erp在左半球内显着更加负性。在响应英语音素对比时记录的左侧电极N1内的平均振幅差异显著地预测了该样本的英语单词阅读能力。结果表明，在左颞叶N1成分电极上记录的母语对比语音感知与早期学龄儿童的英语单词阅读能力有关。

期刊介绍： The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
