The numerical Stroop task involves presenting participants with two digits that differ in physical size and numerical value and asking them to report which digit had the larger size or value while ignoring the other dimension. Previous studies show that participants have difficulty ignoring the irrelevant dimension and thus have implications on the automaticity of numerical processing. The present study investigates the automatic influence of numerical value on numerosity processing in a novel Stroop-like task. In two experiments, participants were presented with digits made of colored stripes and asked to identify the number of different colors. In both experiments, interference and facilitation effects were found, supporting the automaticity of symbolic number processing and its influence on numerosity processing. These findings expand upon previous research on numerical as well as counting Stroop tasks, and have potential implications for studying interference and basic numerical processing in children and clinical populations.
数字斯特鲁普任务要求向参与者呈现两个在物理大小和数值上不同的数字，并要求他们报告哪个数字的大小或值更大，同时忽略另一个维度。先前的研究表明，参与者难以忽略无关维度，因此对数字处理的自动性有影响。本研究在一项新颖的类似斯特鲁普任务中调查了数值对数量处理的自动影响。在两个实验中，向参与者呈现由彩色条纹组成的数字，并要求他们识别不同颜色的数量。在两个实验中，均发现了干扰和促进效应，支持了符号数字处理的自动性及其对数量处理的影响。这些发现扩展了先前关于数字以及计数斯特鲁普任务的研究，并对研究儿童和临床人群中的干扰和基本数字处理具有潜在意义。
