Two experiments were performed to investigate the magnitude of the confound in the standard control condition of the Stroop experiment. The confound resides in the fact that only color changes from one item to the next in the control condition, whereas both color and configuration of the items that represent color change in the usual experimental conditions. The results of both experiments showed small but significant increases in color-naming time when both colors and non-verbal shapes changed from one item to the next. These findings are discussed in the context of the role of factors in selective attention in the color-naming task. While response competition appears to be the more substantial source of interference in Stroop color-word effects, a smaller but more general source of interference due to selective attention appears in whole-list tasks with more than one dimension of item-to-item change.
进行了两项实验，以研究斯特鲁普实验标准控制条件下混淆因素的程度。这种混淆在于这样一个事实：在控制条件下，只有颜色从一个项目到下一个项目发生变化，而在通常的实验条件下，代表颜色变化的项目的颜色和形状都会改变。两项实验的结果均表明，当颜色和非语言形状从一个项目到下一个项目都发生变化时，颜色命名时间虽有小幅但显著的增加。这些发现是在颜色命名任务中选择性注意因素的作用背景下进行讨论的。虽然反应竞争似乎是斯特鲁普颜色-单词效应中更主要的干扰源，但在具有多个项目到项目变化维度的全列表任务中，由于选择性注意而产生的较小但更普遍的干扰源也会出现。
