摘要/Abstract

摘要： 当要求被试对数字进行奇偶判断时，左手对小数的反应较快，而右手对大数的反应较快，该现象被称为空间数字反应编码联合效应（SNARC效应）。大量研究证实了SNARC效应的存在，该效应表明人类对数字的加工受空间表征和空间注意的影响。该文系统地回顾了SNARC效应存在及其发生阶段的证据，对比了Simon效应与SNARC效应，最后尝试着从空间注意的角度挖掘数字和空间的本质联

Abstract: When participants judge the parity of presented digits, left-hand responses are faster for numerically small numbers, whereas right-hand responses are faster for large numbers. This association of numbers with space was termed Spatial-Numerical Association of Response Codes (SNARC effect). A number of experiments have proved this effect, It indicates that both spatial representation and attention influence the course of human number processing. This paper systematically reviewed the evidences of SNARC effect and its functional locus , then SNARC and Simon effects were contrasted. In the end, attention perspective was considered to further explore the essence of spatial-numerical association

Key words: Mental number line, SNARC effect, Spatial representation
