项目特定比例一致性（ISPC）效应是指与主要以一致格式出现的项目相比，主要以不一致格式出现的项目（例如单词）的斯特鲁普效应的减少。它被认为展示了单词阅读过程的反应控制。在本研究中，我们测试了这样一个假设：在颜色词 Stroop 任务中使用明确的、逐次试验的一致性预兆来主动引导注意力可以减少原本强大的 ISPC 效应。在实验 1 中，预提示操作与传统上被认为影响单词阅读过程主动控制的操作一起使用（即列表比例一致性 [list PC]）。使用 100% 有效的预提示来预提示参与者消除了 ISPC 效应和列表 PC 效应。在实验 2 中，我们使用 70% 有效的一致性预提示来指导参与者在给定的试验中普遍预期冲突或一致性。当参与者预计会发生冲突时，ISPC 效应会选择性地降低。这些结果表明，预先提示会影响主动控制的参与，从而减少特定项目和基于列表的倾向对将注意力转向或远离单词阅读的影响。
The item-specific proportion congruency (ISPC) effect refers to the reduction in the Stroop effect for items (e.g., words) that mostly appear in an incongruent format, as compared to items that mostly appear in a congruent format. It is thought to demonstrate reactive control of word-reading processes. In the present study, we tested the hypothesis that using explicit, trial-by-trial congruency precues to proactively guide attention during a color-word Stroop task could reduce the otherwise robust ISPC effect. In Experiment 1, the precueing manipulation was employed alongside a manipulation traditionally thought to influence proactive control of word-reading processes (i.e., list proportion congruence [list PC]). Precueing participants with 100 %-valid precues eliminated both the ISPC effect and the list PC effect. In Experiment 2, we used 70 %-valid congruency precues to direct participants to generally expect conflict or congruence on a given trial. ISPC effects were selectively reduced when the participants expected conflict. These results suggest that precueing influences engagement in proactive control and, as a result, reduces the impact of item-specific and list-based tendencies to direct attention toward or away from word reading.
