采用听觉动窗法和跨通道探测技术,设计3个实验考察了汉语口语句子理解中,动词隐含因果性和重读对代词加工的影响及其时间进程。实验1中自变量为动词类型和韵律特征;实验2、3中增加探测词类型变量。结果发现:动词隐含因果性影响代词的指认方向;当代词不重读时,动词隐含因果性在遇到代词后立即影响代词可能先行词的激活水平。代词重读影响“因为”分句的阅读时间,且在代词后立即影响主语型动词语句中代词的加工。
Introduction There are many factors influencing pronoun processing in spoken language comprehension, such as implicit verb causality and accentuation. Numerous studies ( McDonald & MacWhinney, 1995 ; Garnham, Traxler & Oakhill, et al, 1996 ; Debra & Long, 2000; Sun Y, Shu H, Zheng X, et al 2001 ) have shown that implicit verb causality influenced pronouns resolution. Focus hypothesis and integration hypothesis( Stewart, 2000)both claim that implicit causality makes some candidate antecedent prominent. However, these studies are not consistent on its time course on pronoun processing: on line or off line. In spoken language domain, researchers(Akmajian, 1970; Cahn, 1995; Kameyama, 1999; Venditti,Stone & Tepper, 2001; Wang D & Yang Y, 2004) have studied the effect of accentuation on pronoun processing but have not come to a conclusion. Some researchers claim that stressed pronoun shifts the center of attention, whereas others argue that it only works in parallel-structure sentences. As mentioned above, different prominence of candidate antecedents arisen by implicit verb causality provides us a natural instance for observing the effect of accentuation. The present study aimed to explore the effects of implicit verb causality and accentuation on pronoun processing during spoken Chinese sentence comprehension as well as their time course, using auditory moving window technique ( experiment 1 ) and cross-modal probe method ( experiment 2 and 3 ), by comparing the comprehension time, percentage of choosing NP1, reaction time to probe words between NP1 verb and NP2 verb level, stressed pronoun and unstressed pronoun level. Method One hundred and one paid volunteers participated in the study (30, 20, and 21 in experiments 1,2, and 3, respectively). In the self-paced listening paradigm, participants listened to the sentences clause-by-clause and interpreted the pronoun. In the cross-modal probe procedure, sentences were presented by earphone and the probe word (NP1, NP2) was p
