: Verbal communication comprises the retrieval of semantic and syntactic information elicited by various kinds of words (i.e., parts of speech) in a sentence. Content words, such as nouns and verbs, convey essential information about the overall meaning (semantics) of a sentence, whereas function words, such as prepositions and pronouns, carry less meaning and support the syntax of the sentence. : This study aimed to identify neural correlates of the differential information retrieval processes for several parts of speech (i.e., content and function words, nouns and verbs, and objects and subjects) via electroencephalography performed during English spoken-sentence comprehension in thirteen participants with normal hearing. Recently, phoneme-related information has become a potential acoustic feature to investigate human speech processing. Therefore, in this study, we examined the importance of various parts of speech over sentence processing using information about the onset time of phonemes. : The distinction in the strength of cortical responses in language-related brain regions provides the neurological evidence that content words, nouns, and objects are dominant compared to function words, verbs, and subjects in spoken sentences, respectively. : The findings of this study may provide insights into the different contributions of certain types of words over others to the overall process of sentence understanding.
言语交际包括通过句子中的各种词（即词性）来提取语义和句法信息。实词，如名词和动词，传达句子整体意义（语义）的基本信息，而虚词，如介词和代词，意义较少，支持句子的句法。本研究旨在通过对 13 名正常听力参与者在英语口语句子理解过程中进行的脑电图，确定不同词性（即实词和虚词、名词和动词、宾语和主语）的差异信息检索过程的神经相关性。最近，音位相关信息已成为研究人类言语处理的潜在声学特征。因此，在这项研究中，我们使用音位起始时间的信息来检查各种词性在句子处理中的重要性。语言相关脑区皮质反应强度的差异为内容词、名词和宾语相对于功能词、动词和主语在口语句子中分别占主导地位提供了神经学证据。这项研究的结果可能为理解句子的整体过程中某些类型的词与其他词的不同贡献提供了新的视角。
