Studies of the Stroop color-word task have provided evidence for the existence of two conflicts: (1) an early task conflict between noting the relevant color and reading afforded by the irrelevant word (or word-like stimuli), and (2) a late information conflict between the information provided by the word and the information provided by the color. Measurements of pupil changes, in addition to reaction time (RT), have extended understanding regarding these two conflicts. The current work examines the generalizability of such understanding. We ask whether similar processes work in the comparative judgment of numbers (e.g., in the numerical Stroop task). We present two experiments that support and extend the knowledge gained in the word-color context to numerical processing. Similar to results with the Stroop color-word task, we found a dissociation between RT and pupillometry and an early task conflict followed by an information conflict.
对斯特鲁普颜色-词语任务的研究提供了两种冲突存在的证据：（1）在注意相关颜色和阅读无关单词（或类似单词的刺激）提供的信息之间的早期任务冲突，以及（2）在单词提供的信息和颜色提供的信息之间的晚期信息冲突。除了反应时间 (RT) 之外，瞳孔变化的测量还扩展了对这两种冲突的理解。目前的工作检验了这种理解的普遍性。我们想知道类似的过程是否适用于数字的比较判断（例如，在数字斯特鲁普任务中）。我们提出了两个实验，这些实验支持并扩展了在单词-颜色语境中获得的知识到数字处理中。与斯特鲁普颜色-词语任务的结果相似，我们发现 RT 和瞳孔测量之间存在分离，以及早期任务冲突和信息冲突。
