汉字、数字和符号的身份信息和位置信息加工比较——中文阅读的特别机制

The Identity and Position Processing for Chinese Character,Digit,and Symbol Strings——Special Mechanism of Chinese Reading

汉字、数字和符号的身份信息和位置信息加工存在怎样的差异,以及在不同呈现方式下是否表现不同,现在仍不清楚。本研究采用9选1部分报告范式,通过字符串水平呈现和竖直呈现两个实验来对这一问题进行探究。结果发现,水平呈现对于不同类型字符的身份信息和位置信息加工都更有优势。数字在不同呈现方式下都表现出绝对优势,且水平呈现时存在首位置优势,表明“改变的接受域”理论对于汉语语系地区数字系列位置效应解释的可能性。同时,汉字与符号更为相似,但水平呈现时汉字位置信息加工更好,且表现出更为明显的注视点左侧(包括注视点)优势,这可能是中文阅读的特别机制。

It is still unclear what differences exist in the identity and position processing of Chinese characters,digits and symbols,and whether they perform differently in different presentation modes.We conducted two experiments(random strings aligned horizontally and vertically)using a nine-alternative forced-choice(9AFC)partial reporting task to explore this issue.The results showed that horizontal presentation had more advantages for identity and position processing of different types of strings.The processing of digits showed absolute superiority in different presentation modes,and there was a first position advantage in horizontal presentation.This indicates that there is possibility for the theory of"Modified Receptive Field"to explain the serial position effect for digits in Chinese language region.Chinese characters were more similar to symbols,but they had better position processing and more obvious left fixation(including fixation)advantage in horizontal presentation,which may be the special mechanism of Chinese reading.
