Using the cross-modal priming paradigm, we attempted to determine whether semantic representations for word-final morphemes embedded in multisyllabic words (e.g.,/lak/in /hemlak/) are independently activated in memory. That is, we attempted to determine whether the auditory prime, /hemlak/, would facilitate lexical decision times to the visual target, KEY, even when the recognition point for /hemlak/ occurred prior to the end of the word, which should ensure deactivation of all lexical candidates. In the first experiment, a gating task was used in order to ensure that the multisyllabic words could be identified prior to their offsets. In the second experiment, lexical decision times for visually presented targets following spoken monosyllabic primes (e.g., /lak/-KEY) were compared with reaction times for the same visual targets following multisyllabic pairs (/hemlak/-KEY). Significant priming was found for both the monosyllabic and the multisyllabic conditions. The results support a recognition strategy that initiates lexical access at strong syllables (Cutler & Norris, 1988) and operates according to a principle of delayed commitment (Marr, 1982).
我们采用跨模态启动范式，试图确定多音节词中词尾语素的语义表征（如/hemlak/中的/lak/）在记忆中是否被独立激活。也就是说，我们试图确定听觉启动词/hemlak/是否会加快对视觉目标词KEY的词汇判断时间，即便/hemlak/的识别点出现在单词结束之前，而这应该能确保所有词汇候选词都被停用。在第一个实验中，我们使用了一个选听任务，以确保在多音节词结束之前就能识别它们。在第二个实验中，我们比较了在单音节启动词（如/lak/-KEY）之后视觉呈现目标词的词汇判断时间，以及在多音节词对（/hemlak/-KEY）之后相同视觉目标词的反应时间。在单音节和多音节条件下均发现了显著的启动效应。结果支持了一种识别策略，该策略在强音节处启动词汇提取（Cutler & Norris，1988），并根据延迟承诺原则运作（Marr，1982）。
