阿拉伯数字与汉字大写数字认知的大脑功能一侧化实验研究

用半视野速示术检查阿拉伯数字和汉字大写数字在三种任务加工条件（认读、简单相加、奇偶概念异同判断）下进行认知的大脑两半球机能活动一侧化效应。结果表明：以被试正确反应的百分数为指标，两类数字的三种任务加工均没有表现出明显的视野（大脑半球）优势。以被试正确反应的反应时为指标，两类数字的认读和简单相加也未出现视野（大脑半球）的明显差别，而两类数字的奇偶概念异同判断却出现了差异显著的右视野（左半球）优势。

AN EXPERIMENTAL STUDY ON FUNCTIONAL HEMISPHERIC LATERALIZATION IN COGNITIVE PROCESSING ARABIC NUMERALS AND NUMERALS IN CAPITALS OF CHINESE CHARACTERS

Tachistoscopic visual half-field test was used to investigate functional hemispheric laterality for three kinds of cognitive processing task (reading,simple addition and conceptual decision)on Arabic numerals and numerals in capital of Chinese characters.The results were as follows:1 When determined by percentage of correct reaction,there were no significant hemispheric advantages on all three tasks for two kinds of numerals.2When determined by reaction-time of correct reaction,there was a significant right visual half-field(left hemisphere)advantage on odd-even conceptual decision task but not on reading and simple addition tasks for two kinds of numerals.
