摘要 词汇歧义是语言歧义的一种,词汇歧义消解受到相对意义频率和语境的影响。半视野研究发现大脑两半球都能在词汇歧义消解过程中根据语境信息选择性地激活歧义词的恰当意义、抑制不恰当意义,其中左半球的语义选择功能更强;脑损伤研究发现大脑左、右半球损伤都会导致词汇歧义消解中语义选择障碍,词汇歧义消解需要大脑两半球的联合作用;神经成像研究进一步发现额叶与颞叶共同支持词汇歧义消解,歧义词的恰当意义的选择是由额下回执行的,语义整合加工是由颞叶负责的。 One important issue on language is how the Previous studies with various paradigms reveal that brain processes and represents lexical semantics. sentential information can be used to suppress contextually inappropriate meanings in the LH but not in the RH. However, recent studies find RH not only activate a broader semantic field, but also use contextual information to resolute lexical ambiguity. Neuroimaging studies indicate that lexical ambiguous words are mediated by strong brain activations in the left-dominant network of fronto-temporal brain regions. The IFG plays an important role in selecting an appropriate meaning and inhibiting inappropriate meaning from multiple alternatives.
