用三个实验探索了重读在口语语篇理解加工中的作用。其中实验 1利用以句子为单位的口语动窗法 ,考察了重读如何影响语篇的临场加工速度。实验 2和实验 3利用词汇再认任务 ,考察了重读对语篇临场加工效果 (即信息在语篇表征中的激活水平 )的影响。结果表明 :与控制条件相比 ,一致性重读加快语篇的临场加工 ,不一致性重读减慢语篇的理解加工 ; 与控制条件相比 ,一致性重读提高了新信息在语篇表征中的激活水平 ; 不一致性重读虽然促进了所标示的旧信息的激活 ,但是对于相对重要的新信息的激活具有抑制作用。从而说明一致性重读对语篇理解具有促进作用 ,而不一致性重读阻碍语篇理解。这一促进和抑制作用不仅体现于语篇的临场加工过程中 ,而且表现在即时的语篇加工效果中

Three experiments were carried out to investigate the role accentuation plays in spoken discourse comprehension . The first experiment examined how accentuation influenced on-line processing speed during discourse comprehension , using sentence-by-sentence auditory moving window technique. The second and third experiments explored the effect of accentuation on the immediate results of discourse processing (namely the activation of information in discourse representation) , using word recognition task. The results showed that : compared to neutral accentuation , appropriate accentuation speeded up discourse processing and inappropriate accentuation slowed discourse processing ; compared to neutral accentuation , appropriate accentuation enhanced the activation of new information in discourse representation ; however , inappropriate accentuation suppressed the activation of important new information although it enhanced the activation of old information it marked. Therefore , appropriate accenting accelerated discourse comprehension and inappropriate accentuation impeded discourse processing , both were exhibited both in on2line processing time and in the immediate result of discourse processing.
