Abstract: With Chinese listeners as participants, the study examined the time courses of stop consonant activation using context effect tasks. Experiment 1 examined the context effects of stop acoustic features. A /ta/-/ka/ continuum acted as target stimuli, the acoustic analogues of initial 80-ms segments of syllables /ta/ and /ka/, and acoustic analogues of syllables /ta/ and /ka/ acted as context stimuli. The results showed that neither syllable analogs nor stop segment analogs exhibited context effects. Experiment 2 examined the context effects of stop phonetic categories. Syllables /ta/ and /ka/, and 80-ms stop segments acted as context stimuli. The results found that both endpoint syllables and 80-ms segments showed contrastive context effects. Experiment 3 varied ISI between stop segments and target stimuli to examine the time courses of stop category activation. The results showed that the transition from auditory processing to phonetic processing stage occurs about 120 ms after stimuli processing. The present findings disclose the time courses of stop auditory and phonetic processing.

摘要: 采用语境效应范式,以汉语听者为被试,在三个实验中考察了塞辅音声学信息和语音信息激活的时间进程。实验1语境刺激是/ta/、/ka/音节和/ta/、/ka/塞音段的声学模拟音,目标刺激是/ta/-/ka/对比连续体,结果发现,塞音声学信息激活没有产生语境效应。实验2语境刺激是/ta/、/ka/音节和/ta/、/ka/塞音段,结果发现塞音语音信息激活产生了显著的对比语境效应。实验3变化塞音段和目标刺激之间的间隔,系统考察塞音范畴通达的时间进程,结果发现,塞音知觉中听觉加工阶段向语音加工阶段的转变约发生于刺激加工后120 ms。实验结果揭示了塞辅音知觉中音位范畴通达的时间进程。
