Two cross-modal priming experiments investigated whether the representation of either an initial- or a final-embedded word may be activated when the longer carrier word is auditorily presented. Visual targets were semantically related either to the embedded word or to the carrier word or they were unrelated to the primes. A priming effect was found for semantic associates of the carrier word in both experiments as well as for associates of the final-embedded word (Experiment 2). These results suggest that mapping speech onto lexical representations may imply lexical access attempts at several points during auditory processing of the speech signal.
两项跨模态启动实验研究了,当较长的载体词通过听觉呈现时,词首或词尾嵌入词的表征是否会被激活。视觉目标在语义上要么与嵌入词相关,要么与载体词相关,要么与启动词无关。在两项实验中均发现了载体词语义联想词的启动效应,以及词尾嵌入词语义联想词的启动效应(实验2)。这些结果表明,将语音映射到词汇表征上可能意味着在语音信号的听觉处理过程中的多个点上进行词汇通达尝试。
