Dehaene、Bossini和Giraux（1993）发现，受试者对右侧选择的大数字的反应要快于左侧选择的反应，而对小数字的反应则相反（SNARC效应）。根据Dehaene等人（1993）的研究，SNARC效应取决于数字的定量表示，例如从左到右的模拟数字线。本研究的主要目标是双重的：第一，调查是否可以观察到垂直SNARC效应，第二，以验证是否Dehaene等。的解释是正确的。实验2A和2B显示了奇偶判断任务中的垂直SNARC效应。受试者对大数字的反应快于顶部的选择，而对小数字的反应则相反。然而，实验3未能显示SNARC效应在数量大小判断任务，这表明数量表征可以从产生SNARC效应的空间代码分离。
Dehaene, Bossini, and Giraux (1993) revealed that subjects responded to large numbers faster with the choice on the right than with the choice on the left, whereas the reverse held true for small numbers (SNARC effect). According to Dehaene et al. (1993), the SNARC effect depends on the quantitative representation of number, such as a left-to-right-oriented analog number line. The main goal of the present study was twofold: first, to investigate whether the vertical SNARC effect could be observed, and, second, to verify whether Dehaene et al.'s (1993) explanation of the SNARC effect is correct. Experiments 2A and 2B showed the vertical SNARC effect in a parity judgment task. Subjects responded to large numbers faster with the top choice than with the bottom choice, whereas the reverse held true for small numbers. However, Experiment 3 failed to show the SNARC effect in a number magnitude judgment task, suggesting that the quantitative representation could be dissociated from the spatial code that produces the SNARC effect.
