本文通过两个实验考察现代汉语双音节名词和动词典型性效应和词性效应。实验一采用单独呈现的词汇判断实验发现:名词典型性效应发生在低频条件下,高频条件下典型性差异不显著。动词典型性效应在高频和低频条件下均不显著,动词和名词的词性效应在高频和低频条件下均显著。实验二通过句子语境条件下的眼动实验发现:低频条件下仍存在名词典型性效应,但名词和动词的词性效应消失。文章还对上述发现作了理论上的解释。 This article examines the typical effects and part-of-speech effects of nouns and verbs in modern Chinese through two experiments. In the first experiment, we found that the typical effect of nominals was found under the condition of low frequency, but the typical difference was not significant under high frequency. The typical effects of verbs were not significant at high frequency and low frequency, and the part of speech and noun of the verbs were both significant at high frequency and low frequency. In the second experiment, we found that under the condition of low sentence frequency, there are still nouns typical effects, but the part of speech and verbs disappear. The article also made a theoretical explanation of the above findings.
