中文摘要：

为考察数字空间表征的特点和可变性,运用实验法对30余名大学生进行了研究.实验1采用单手奇偶判断任务,实验2在实验1的基础上增加了从左至右或者从右至左的稳定空间启动,结果发现：实验1中被试表现出了明显的SNARC效应;实验2中从左至右稳定的空间位置启动能增强SNARC效应,而相反方向稳定的空间位置启动能削弱SNARC效应.结果表明SNARC效应不受按键距离的影响,且SNARC效应具有一定程度的可变性.结果能为数学认知发展、数学教学以及数学障碍提供理论基础.

英文摘要：

T he present study aimed at investigating the characteristics and changeability of number-spatial representation .Over thirty participants have been recruited in both experiments .The odd-even identifica-tion task has been used in experiment 1 and steady spatial priming either from left to right or from right to left have been added in experiment 2 .Results suggest that significant SNARC effect is found in experiment 1 and the SNARC effect is strengthened by spatial priming from left to right ;but reduced by spatial prim-ing in the opposite direction in experiment 2 .These findings suggest that the distance of response keys do not affect SNARC effect ;and SNARC effect is changeable .These findings could serve as theoretical bases for development of mathematical cognition as well as mathematical disorders .
