Tzelgov and colleagues [Tzelgov, J., Meyer, J., and Henik, A. (1992). Automatic and intentional processing of numerical information. Journal of Experimental Psychology: Learning, Memory and Cognition, 18, 166-179.], offered the existence of the laterality effect as a post-hoc explanation for their results. According to this effect, numbers are classified automatically as small/large versus a standard point under autonomous processing of numerical information. However, the genuinity of the laterality effect was never examined, or was confounded with the numerical distance effect. In the current study, I controlled the numerical distance effect and observed that the laterality effect does exist, and affects the processing of automatic numerical information. The current results suggest that the laterality effect should be taken into account when using paradigms that require automatic numerical processing such as Stroop-like or priming tasks.
泽尔戈夫及其同事[泽尔戈夫，J.，迈耶，J.，和赫尼克，A.（1992年）。数字信息的自动和有意加工。《实验心理学杂志：学习、记忆与认知》，18，166 - 179。]，提出存在偏侧性效应，作为对其研究结果的事后解释。根据这种效应，在数字信息的自主加工过程中，数字会自动与一个标准点相对比，被分类为小/大。然而，偏侧性效应的真实性从未被检验过，或者与数字距离效应混淆了。在当前的研究中，我控制了数字距离效应，观察到偏侧性效应确实存在，并且会影响自动数字信息的加工。当前的结果表明，在使用需要自动数字加工的范式，如类斯特鲁普或启动任务时，应该考虑偏侧性效应。
