A lexical decision experiment investigated hemisphere asymmetries in resolving lexical ambiguity within a sentence context. Sentences that biased a single meaning (either dominant or subordinate) of sentence-final ambiguous words were followed by a lateralized target related to the sentence-congruent or -incongruent meaning of the ambiguous word, or an unrelated word. In the RVF sentence-congruent targets were facilitated, while incongruent targets were not primed. In contrast, related targets were facilitated in the LVF, regardless of sentence context. This suggests that selecting the contextually appropriate word meaning requires the left hemisphere, and supports a right hemisphere role in maintaining alternate word senses.
一项词汇判断实验研究了在句子语境中解决词汇歧义时的半球不对称性。偏向句末歧义单词单一意义（主导或从属）的句子后面跟着一个与歧义单词的句子一致或不一致意义相关的侧化目标，或者一个无关单词。在右视野中，与句子一致的目标得到促进，而不一致的目标没有被启动。相比之下，无论句子语境如何，左视野中的相关目标都得到促进。这表明选择符合语境的词义需要左半球，并支持右半球在维持替代词义方面的作用。
