It is well supported that stimulus-driven control of attention varies depending on the degree of conflict previously encountered in a given location. Previous research has further shown that control settings established in conflict-biased locations can transfer to nearby unbiased items. However, these spatial transfer effects have only been shown using incompatible flanking arrows (i.e., stimuli that trigger spatial information) to elicit conflict in a flanker task. Here we examine the generalizability of transfer of control by examining if it can occur across a range of tasks. We employ a classic Stroop task (Experiment 1), a spatially segregated Stroop task (Experiment 2), and a spatial Stroop task (Experiment 3). Location-specific proportion compatibility effects were observed in all variations of the Stroop task tested; however, transfer to unbiased items occurred only in the spatial Stroop task in Experiment 3. This suggests that the transfer of cognitive control settings within spatial categories may occur only in tasks where the source of conflict is spatial, as arises in tasks with arrow and direction word stimuli.
有充分的证据表明,由刺激驱动的注意力控制会因在给定位置先前遇到的冲突程度而有所不同。先前的研究进一步表明,在有冲突偏向的位置建立的控制设置可以转移到附近无偏向的项目上。然而,这些空间转移效应仅在侧翼任务中使用不相容的侧翼箭头(即触发空间信息的刺激)来引发冲突时得到了证明。在这里,我们通过研究控制转移是否能在一系列任务中发生来检验其普遍性。我们采用了经典的斯特鲁普任务(实验1)、空间分离的斯特鲁普任务(实验2)和空间斯特鲁普任务(实验3)。在所测试的斯特鲁普任务的所有变体中都观察到了特定位置的比例相容性效应;然而,仅在实验3的空间斯特鲁普任务中出现了向无偏向项目的转移。这表明,认知控制设置在空间类别内的转移可能仅发生在冲突源是空间的任务中,如在带有箭头和方向词刺激的任务中那样。
