Previous research indicates that mental representations of word meanings are distributed along both semantic and syntactic dimensions such that nouns and verbs are relatively distinct from one another. Two experiments examined the effect of representational distance between meanings on recognition of ambiguous spoken words by comparing recognition of unambiguous words, noun-verb homonyms, and noun-noun homonyms. In Experiment 1, auditory lexical decision was fastest for unambiguous words, slower for noun-verb homonyms, and slowest for noun-noun homonyms. In Experiment 2, response times for matching spoken words to pictures followed the same pattern and eye fixation time courses revealed converging, gradual time course differences between conditions. These results indicate greater competition between meanings of ambiguous words when the meanings are from the same grammatical class (noun-noun homonyms) than they when are from different grammatical classes (noun-verb homonyms).
先前的研究表明，词义的心理表征沿着语义和句法维度分布，使得名词和动词相对彼此不同。两项实验通过比较明确词、名动同音异义词和名名同音异义词的识别情况，研究了词义之间的表征距离对模糊口语词识别的影响。在实验1中，明确词的听觉词汇判断最快，名动同音异义词较慢，名名同音异义词最慢。在实验2中，将口语词与图片匹配的反应时间遵循相同模式，并且眼动注视时间进程揭示了不同条件之间逐渐趋同的时间进程差异。这些结果表明，当模糊词的词义来自相同语法类别（名名同音异义词）时，其词义之间的竞争比来自不同语法类别（名动同音异义词）时更大。
