Studies have widely captured the spatial-numerical association of response codes (SNARC) effect in the processing of various types of numbers in which small numbers are responded to faster with the left hand than with the right hand and larger numbers are responded to faster with the right hand than with the left hand. Although a few studies have explored Arabic numbers to further investigate the influence of number location on the SNARC effect, it remains unclear whether the influence of number location on the SNARC effect is moderated by numerical semantic processing difficulty and the task performed. This study explored traditional Chinese numerical words and rotated them to certain angles, which can increase numerical semantic processing difficulty, to further investigate the influence of the stimulus-response compatibility effect and Simon effect on the SNARC effect in a space classification task (Experiment 1), numerical magnitude classification task (Experiment 2), numerical parity classification task (Experiment 3), and color classification task (Experiment 4). The results indicated that (a) the stimulus-response compatibility effect, not the SNARC effect, prevailed in the numerical space classification task; (b) the SNARC effect, not the Simon effect, prevailed in the numerical magnitude and parity classification task; and (c) the Simon effect and the SNARC effect coexisted in the color classification task. These results suggested that the influence of number location on the SNARC effect was moderated by the task performed. Implications for the theory of the SNARC effect and Simon effect are discussed.
研究广泛捕捉到了反应编码的空间-数字关联（SNARC）效应，即在处理各类数字时，较小数字用左手反应比用右手更快，而较大数字用右手反应比用左手更快。尽管有一些研究探讨了阿拉伯数字，以进一步研究数字位置对SNARC效应的影响，但数字位置对SNARC效应的影响是否受到数字语义加工难度和所执行任务的调节仍不清楚。本研究探讨了繁体中文数字词，并将它们旋转到一定角度，这可以增加数字语义加工难度，以在空间分类任务（实验1）、数字大小分类任务（实验2）、数字奇偶分类任务（实验3）和颜色分类任务（实验4）中进一步研究刺激-反应兼容性效应和西蒙效应对SNARC效应的影响。结果表明：（a）在数字空间分类任务中，占主导的是刺激-反应兼容性效应，而非SNARC效应；（b）在数字大小和奇偶分类任务中，占主导的是SNARC效应，而非西蒙效应；（c）在颜色分类任务中，西蒙效应和SNARC效应共存。这些结果表明，数字位置对SNARC效应的影响受到所执行任务的调节。文中讨论了这些结果对SNARC效应和西蒙效应理论的启示。
