中文摘要: 注意是语言理解过程中的重要元素,但是以往心理语言学研究着重于考察语言各个模块之间(比如句法、语义和音系)的关系,较少涉及到注意作为基本的认知元素在语言理解中所起的作用。已有研究表明信息结构和情绪都能够调控注意资源,因此本项目以信息结构和情绪为切入点,拟使用脑电和功能磁共振成像技术对它们在语言理解中调控注意的认知神经机制进行探索。首先,我们考察信息结构在语言理解中所激活的大脑网络,并将其与知觉加工中所涉及的注意网络进行比较,以此来揭示语言理解过程中是否激活了一般性注意网络;其次,考察情绪信息对句子中其他词语加工的影响,以此来揭示情绪信息调控注意资源的广度;最后,从时间和空间两个维度上考察信息结构和情绪在调控注意资源中的交互作用。通过上述研究,我们将揭示语言理解在一般认知框架下的加工过程;同时,本研究结果能为注意缺陷所导致的语言理解障碍的评估及康复治疗提供理论依据。

英文摘要: It is well known that attention plays a crucial role in language comprehension. However, most studies in the psycholinguistic field have focused on the interplay among linguistic modulars (such as syntax, semantics and phonology), leaving the influence of attention on language comprehension largely unknown. Given that both information structure and emotion could serve to modulate attention, we will use EEG and fMRI techniques to investigate their influences on language comprehension as well as the underlying neural mechanisms. First, we will compare the brain regions activated by information structure with the attention network localized in a spatial attention task, thereby testing whether a domain-general attention network is recruited during language comprehension. Second, the degree of attentional influences of emotion will be assessed by examining how emotional information affects its following information processing. Finally, we will study the temporal and spatial characteristics of the interaction between information structure and emotion. The findings will contribute to our understanding of the language comprehension within a general cognitive processing framework. In addition, the results will provide some theoretical basis for the diagnosis and treatment of language impairments related to attentional de
