In a paradigm combining spatial Stroop with spatial cueing, the current study investigated the role of the presence vs. absence of placeholders on the reduction of the spatial Stroop effect by peripheral cueing. At a short cue-target interval, the modulation of peripheral cueing over the spatial Stroop effect was observed independently of the presence/absence of placeholders. At the long cue-target interval, however, this modulation over the spatial Stroop effect only occurred in the placeholders-present condition. These findings show that placeholders are modulators but not mediators of the reduction of the spatial Stroop effect by peripheral cueing, which further favor the cue-target integration account.
在结合空间斯特鲁普和空间提示范式的研究中，本研究考察了在空间斯特鲁普效应中，占位符的存在与否对周边提示的影响。在短的提示-目标间隔下，外周提示对空间斯特鲁普效应的调节与占位符的存在与否无关。然而，在长的提示-目标间隔下，这种对空间斯特鲁普效应的调节仅发生在占位符存在的情况下。这些发现表明，占位符是外周提示减少空间斯特鲁普效应的调节因素，而不是中介因素，这进一步支持了提示-目标整合理论。
