Phonological priming between bisyllabic (CV.CVC) spoken items was examined using both behavioral (reaction times, RTs) and electrophysiological (event-related potentials, ERPs) measures. Word and pseudoword targets were preceded by pseudoword primes. Different types of final phonological overlap between prime and target were compared. Critical pairs shared the last syllable, the rime or the coda, while unrelated pairs were used as controls. Participants performed a target shadowing task in Experiment 1 and a delayed lexical decision task in Experiment 2. RTs were measured in the first experiment and ERPs were recorded in the second experiment. The RT experiment was carried out under two presentation conditions. In Condition 1 both primes and targets were presented auditorily, while in Condition 2 the primes were presented visually and the targets auditorily. Priming effects were found in the unimodal condition only. RTs were fastest for syllable overlap, intermediate for rime overlap, and slowest for coda overlap and controls that did not differ from one another. ERPs were recorded under unimodal auditory presentation. ERP results showed that the amplitude of the auditory N400 component was smallest for syllable overlap, intermediate for rime overlap, and largest for coda overlap and controls that did not differ from one another. In both experiments, the priming effects were larger for word than for pseudoword targets. These results are best explained by the combined influences of nonlexical and lexical processes, and a comparison of the reported effects with those found in monosyllables suggests the involvement of rime and syllable representations.
我们使用行为学指标（反应时间，RT）和电生理学指标（事件相关电位，ERP），研究了双音节（CV.CVC）口语项目之间的语音启动效应。单词和假词目标之前呈现假词启动项。比较了启动项和目标项之间不同类型的最终语音重叠情况。关键对共享最后一个音节、韵或尾音，而不相关对用作对照。在实验1中，参与者执行目标跟读任务，在实验2中执行延迟词汇判断任务。在第一个实验中测量反应时间，在第二个实验中记录ERP。反应时间实验在两种呈现条件下进行。在条件1中，启动项和目标项均通过听觉呈现，而在条件2中，启动项通过视觉呈现，目标项通过听觉呈现。仅在单模态条件下发现了启动效应。对于音节重叠，反应时间最快；对于韵重叠，反应时间中等；对于尾音重叠和对照，反应时间最慢，且彼此之间没有差异。ERP是在单模态听觉呈现下记录的。ERP结果表明，对于音节重叠，听觉N400成分的波幅最小；对于韵重叠，波幅中等；对于尾音重叠和对照，波幅最大，且彼此之间没有差异。在两个实验中，单词目标的启动效应都比假词目标大。这些结果最好用非词汇和词汇过程的综合影响来解释，将报告的效应与单音节中发现的效应进行比较表明，韵和音节表征参与其中。
