词汇判断中汉语多义词识别的优势效应

THE EFFECTS OF POLYSEMY FOR CHINESE WORDS IN LEXICAL DECISION

运用词汇判断任务,考察了汉语双字词识别中的多义性效应。实验一运用2个真字任意组合构成的假词(如:镜社)作填充材料,发现多义词识别的优势效应仅仅存在于错误率中。实验二运用与源真词(如:冲锋)同音形似的假词(如:冲烽)作填充材料,促使被试更多地在语义水平上做出判断,结果发现很强的多义词识别的优势效应,这种效应主要表现在低频词上。两个实验结果表明,在词汇判断中用不同的假词作填充词会影响被试的词汇判断策略,从而在不同水平上通达词义。最后,用反馈模型对实验结果进行了解释。

Two experiments were conducted to examine the effects of polysemy in the identification of Chinese two- character words in the lexical decision tasks. In experiment 1,with a filler word (e.g.,镜社) consisting of two Chinese characters ranged randomly,a polysemous advantage effects was observed only in the error rates. In Ex- periment 2,however,with a filler word (e.g.,冲烽) as composed of two Chinese characters which were pseudoho- mophonetic and similar- graph with the two Chinese characters forming a polysemous word (e.g.,冲锋),there were a robust polysemous advantage effects mainly in low frequent words and a significant interaction between polyse- my and frequency. The results of two experiments showed that when different foils were used in the lexical de- cision tasks,subjects adopted different strategies in the different foils contexts,and acceded to the different se- mantic levels of words. The implications of these results for conclusions were best accounted for in terms of the the feedback accounts.
