利用跨通道词汇再认任务,探索了口语临场加工过程中,不一致性重读对新信息以及它所标示的旧信息在语篇表征中激活水平的影响。结果表明:与控制条件相比,不一致性重读虽然提高了旧信息在语篇表征中的激活水平,但是同时抑制了新信息的激活; 这一促进和抑制作用在关键词汇后的500ms就已出现。从而说明,对于相对重要的新信息,不一致性重读会阻碍语篇的理解,并且会影响到语篇的临场加工过程。

Using cross-model word recognition task, this study explored the effect of inconsistent accentuation on activation of new information and correspondent old information in discourse representation, during on-line spoken discourse processing. The results showed that: compared to control condition, although inconsistent accentuation enhanced the old information's activation in discourse representation, it inhibited the activation of new information; the facilitating and inhibiting effect occurred about 500 ms after the offset of the old word which was accented. Therefore, with respect to new information which was important to language processing, inconsistent accentuation impeded spoken discourse comprehension; meanwhile, inconsistent accentuation indeed influenced on-line discourse processing.
