摘　　要：采用Gevers等的实验范式,以判断数字大小并选择汉字左右为任务,材料为阿拉伯数字(1,2,8,9)和汉字符号("左"、"右"),考察在汉字符号("左"、"右")信息下,7～11岁儿童数字认知加工SANRC效应的编码方式.结果发现:在汉字符号信息下,7～11岁儿童在数字大小比较任务中都表现出数字空间联结SNARC效应;7岁、9岁和11岁儿童数字认知SNARC效应的编码方式主要存在视觉空间和言语空间编码,且以言语空间编码为主,说明儿童从7岁开始在对数字进行表征时已能将小数字与言语信息"左"联系,将大数字与言语信息"右"联系,并且数字与言语之间的联结优先于数字与空间之间的联结.In present study, Gevers et al＇s experimental paradigm was used to investigate that the coding modes of 7 to l 1-year-old children＇s SNARC effect of numerical cognition under the symbols of Chinese characters. The stimuli were Arabic numbers （1, 2, 8, 9） and Chinese characters （＂Left＂, ＂Right＂）. Subjects＇ task was to decide whether the presented number was larger or smaller than 5, select Chinese characters of left and right. The results showed that 7 to l 1-year-old children performed the SNARC effect of number-space interactions in the task of numerical comparison under the symbols of Chinese characters,and the coding modes of 7 to ll-year-old children＇s SNARC effect of numerical cogni- tion were visuospatial and verbal-spatial. The verbal-spatial coding was mainly. These results indicated that children from 7 year old could connect the small number with verbal information ＂Left＂ and the large number with verbal information ＂Right＂ when they represented numbers. Moreover, the interaction of number with verbal was in preference to the interaction of number with space.
