Previous laterality studies have implicated the right hemisphere in the processing of metaphors, however it is not clear if this result is due to metaphoricity per se or another aspect of semantic processing. Three divided visual field experiments varied metaphorical and literal sentence familiarity. We found a right hemisphere advantage for unfamiliar sentences containing distant semantic relationships, and a left hemisphere advantage for familiar sentences containing close semantic relationships, regardless of whether sentences were metaphorical or literal. This pattern of results is consistent with theories postulating predominantly left hemisphere processing of close semantic relationships and predominantly right hemisphere processing of distant semantic relationships.
以往关于大脑半球偏侧化的研究表明,右半球在隐喻处理中发挥作用,然而,目前尚不清楚这一结果是由于隐喻本身还是语义处理的其他方面所致。三项视野分割实验改变了隐喻句和直白句的熟悉程度。我们发现,对于包含远距离语义关系的不熟悉句子,右半球具有优势;而对于包含近距离语义关系的熟悉句子,左半球具有优势,无论句子是隐喻性的还是直白的。这一结果模式与以下理论一致,即该理论假定左半球主要处理近距离语义关系,而右半球主要处理远距离语义关系。
