使用行为（反应时间，RTs）和电生理（事件相关电位，erp）测量来检测双音节口语项目之间的语音启动。单词和假词目标前面是假词启动词。比较了启动词和目标词不同类型的韵母重叠。关键的对词共享最后一个音节、韵母或结尾，而不相关的对词作为对照。实验1为目标跟踪任务，实验2为延迟词汇决策任务。第一次实验测量RTs，第二次实验记录erp。RT实验在两种呈现条件下进行。在条件1中，启动物和目标物都是听觉呈现的，而在条件2中，启动物是视觉呈现的，目标物是听觉呈现的。启动效应仅在单峰条件下存在。对于音节重叠，rt反应最快，对于韵母重叠，rt反应中间，对于尾韵重叠和控制，rt反应最慢。在单峰听觉呈现下记录erp。ERP结果显示，音节重叠时，听觉N400分量的振幅最小，时间重叠时，听觉N400分量的振幅居中，尾音重叠和无差异对照时，听觉N400分量的振幅最大。在两个实验中，单词的启动效应都大于伪单词的启动效应。这些结果最好是由非词汇和词汇过程的综合影响来解释的，并且将报告的影响与单音节过程的影响进行比较，表明了韵母和音节表征的参与。
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 nas 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.
