变形汉字的结构方式和笔画数效应

EFFECTS OF CONSTRUCTION WAY AND STROKE NUMBER IN VISUAL PERCEPTION OF TRANSFORMING CHINESE CHARACTERS

曾捷英等提出并采用了汉字通透性概念解释汉字识别中的字形属性效应 ,例如笔画数效应、笔画类型效应和结构方式效应。在有关研究中采用的主要实验方法是在速示、重复速示、非速示、时间或空间微观发生等条件下要求被试命名汉字。该研究将采用新的实验方法 ,即在呈现变形汉字 12 0 0ms后要求被试报告识别内容。结构方式和笔画数两种字形属性为研究对象。实验结果表明存在着常规的结构方式效应和笔画数效应 ,尤为重要的是观察到了逆转的结构方式效应。客观计算出的汉字通透性可以合理地解释这些效应。该研究和先前研究部分证明了关于汉字字形知觉的一个重要假设 :汉字通透性是形成各种字形属性效应的基本或主导原因。字形属性对汉字识别的影响可以归结为通透性的影响 ,这称之为通透性中介假设。

s Zeng et al. proposed that the space transparency of Chinese characters can be used to account for varieties of character form effects in visual perception of Chinese characters, such as, the effects of stroke number, stroke type and construction way. This study applied a new method that subjects were asked to report what they saw after the transforming Chinese characters were presented on screen for 1200ms. The results showed that there were construction way and stroke number effect as people had before disclosed, however, it is important that there is reverse effect of construction way. The space transparency computed according to an algorithm can reasonably account for these effects. This study and previous study can partially prove an important hypothesis on visual perception of Chinese characters that space transparency plays a leading role in varieties of form effects.
