The left hemisphere (LH) is responsible for many fundamental aspects of language; however, converging evidence suggests the right hemisphere (RH) is critically involved in higher-level language comprehension. We examined the extent of each hemispheres' access to a meaningful mental representation of language by recording electroencephalography while participants (N = 44) completed a computer-based task where auditory sentences described individual elements of an image. If integrated successfully, this allowed the construction of a meaningful mental representation. If unsuccessful, the individual elements were in themselves meaningless. Participants saw a lateralised image that was either an integrated representation of the object described in the previous auditory passage ("integrated"), an unintegrated representation of each of the individual elements ("unintegrated"), or an integrated representation of an object that did not match the previous passage ("unrelated"). Evidenced by the trend in N300 amplitudes, we found that both hemispheres accessed a mental representation that embodied the elements described in the preceding passage. However, only the RH distinguished integrated versus unintegrated targets, suggesting that the RH accessed a mental representation that embodied the correct spatial relationships between elements (i.e., perceptual integration) as well as the individual imagined elements (i.e., perceptual elaboration). These results provide evidence of a clear RH contribution to the integration of perceptual information during language comprehension.

语言理解过程中感知整合的半球差异:一项ERP研究。

左半球(LH)负责语言的许多基本方面。但是,越来越多的证据表明,右半球(RH)严重参与了高级语言理解。我们通过记录脑电图检查了每个半球获得有意义的语言心理表达的程度,而参与者(N = 44)完成了一项基于计算机的任务,其中听觉句子描述了图像的各个元素。如果成功整合,就可以构建有意义的心理表征。如果不成功,那么各个要素本身就毫无意义。参与者看到了一张侧面化的图像,该图像是上一听觉段落中描述的对象的整体表示(“整体”),每个单独元素的未集成表示(“未集成”),或与先前段落不匹配的对象的集成表示(“无关”)。通过N300振幅趋势的证明,我们发现两个半球都访问了一个心理表征,该心理表征体现了上一段中描述的元素。但是,只有RH区分了集成目标和未集成目标,这表明RH访问了一种心理表征,体现了元素之间的正确空间关系(即感知整合)以及单个想象的元素(即感知阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。或与先前段落不匹配的对象的综合表示(“无关”)。通过N300振幅趋势的证明,我们发现两个半球都访问了一个心理表征,该心理表征体现了上一段中描述的元素。但是,只有RH区分了集成目标和未集成目标,这表明RH访问了一种心理表征,体现了元素之间的正确空间关系(即感知整合)以及单个想象的元素(即感知阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。或与先前段落不匹配的对象的综合表示(“无关”)。通过N300振幅趋势的证明,我们发现两个半球都访问了一个心理表征,该心理表征体现了上一段中描述的元素。但是,只有RH区分了集成目标和未集成目标,这表明RH访问了一种心理表征,体现了元素之间的正确空间关系(即感知整合)以及单个想象的元素(即感知阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。通过N300振幅趋势的证明,我们发现两个半球都访问了一个心理表征,该心理表征体现了上一段中描述的元素。但是,只有RH区分了集成目标和未集成目标,这表明RH访问了一种心理表征,体现了元素之间的正确空间关系(即感知整合)以及单个想象的元素(即感知阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。通过N300振幅趋势的证明,我们发现两个半球都访问了一个心理表征,该心理表征体现了上一段中描述的元素。但是,只有RH区分了集成目标和未集成目标,这表明RH访问了一种心理表征,体现了元素之间的正确空间关系(即感知整合)以及单个想象的元素(即感知阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。提示RH访问了一种心理表现形式,该表现形式体现了元素之间的正确空间关系(即知觉整合)以及单个想象的元素(即知觉阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。提示RH访问了一种心理表现形式,该表现形式体现了元素之间的正确空间关系(即知觉整合)以及单个想象的元素(即知觉阐述)。这些结果提供了在语言理解过程中RH对感知信息整合的明显贡献的证据。
