进行了三个跨通道启动词汇判断实验 ,探讨汉语听觉词汇加工中声调信息对语义激活的制约作用。实验一和二使用具有相同音段信息、但不同声调信息的双音节合成词 (如“条约”和“跳跃”)作为听觉启动词 ,与其中一个词有语义关系的双字词作为视觉探测词。语义启动词与其配对的声调不匹配词在第一音节的声调、第二音节的声调、或两个声调上有所不同。实验三改变语义启动词的第一或第二音节的声调 ,以产生声调不匹配的假词启动项 ;实验三还同时变化了原来的声调与产生的声调之间的相似性。实验结果表明 ,声调不匹配的启动项目是否产生显著的启动效应取决于词汇竞争的环境、声调输入与深层声调表征之间匹配的程度 ,以及不匹配的声调所在的位置。文章从语音输入中的声调信息如何激活词汇表征、声调信息如何存储在心理词典中、声调对语义激活的制约作用如何受竞争环境的影响这三个方面讨论了研究的发现 Three cross-channel start-up vocabularies were tested to explore the role of tonal information in semantic activation in Chinese auditory vocabulary processing. Experiments one and two use two-syllable words (such as “treaties” and “jumps”) that have the same information of the same section but different tonal information as auditory initiators and double words that have a semantic relationship with one of the words as visual probe words . The tone mismatch between the semantic start and its counterpart differs in the pitch of the first syllable, the pitch of the second syllable, or both tones. Experiment 3 changed the tone of the first or second syllable of the semantic start-up word to generate the unvoiced pseudo-start item. Experiment three also changed the similarity between the original tone and the generated tone. Experimental results show that whether tone-mismatched start-up items have a significant start-up effect depends on the context of the vocabulary competition, the degree of match between tone input and deep tone representation, and the location of mismatched tones. The article discusses the findings from three aspects: how to activate vocabularies in phonetic input, how to store tonal information in mental lexicon, and how the restrictive effect of tone on semantic activation is affected by competitive environment
