汉字识别中的语音效应

PHONOLOGICAL EFFECT FOR IDENTIFICATION OF CHINESE CHARACTERS

该实验用启动掩蔽法探讨了汉字词识别中语音的作用。以五类高、低频汉字词对为材料,在三种启动时间条件下发现:高频形似音同目标字在25毫秒启动下有显著促进效应,而形异音同目标字在25和35毫秒有显著抑制效应。在低频情况下与上述相应的目标字表现出不显著的促进和抑制效应。此结果似乎表明汉字词识别过程具有程度不同的语音自动激活效应。

The present experiment was conducted to examine whether Chinese charac-ter identification is mediated by phonological processes or not. A maskedpriming paradigm was used. Five kinds of character pairs were used as stimuli(orthographically similar; orthographically similar homonym; homophone;synonym; and cotrol character). All of them were divided into higher andlower frequencies. The exposure duration were 40ms for targets and 25, 35,45ms for priming characters. The results showed that there was a significantinhibit effect for homophone targets compared with control targets at 25msand 35ms exposure duration in the condition of higher frequency, And theorthographically similar homonym targets got significant facilitation effect at25ms. In lower frequency condition a significant facilitation was obtained forboth orthographically similar and orthographically similar homonym targetsat three exposure dtirations of priming. And the homophone showed insigni-ficant difference compared to the control targets. The results suggest thatChinese character identification is mediated by phonological processes. Theconditions in which the function of phonology appeared were discussed.
