People reactively adjust attentional control based on the history of conflict experiences at different locations resulting in location-specific proportion compatibility (LSPC) effects. Weidler et al. (2022, Journal of Experimental Psychology: Human Perception and Performance, 48[4], 312-330) found that LSPC effects were larger when stimuli were presented on the horizontal axis (i.e., locations to left and right of fixation) compared with the vertical axis (i.e., locations above and below fixation). They proposed and provided initial evidence suggesting left/right locations may represent a special design feature that leads to stronger LSPC effects (i.e., horizontal precedence account). However, their use of horizontally oriented flanker stimuli, which required participants to traverse through the distracting flankers to select the central target selectively in the horizontal axis condition, may have contributed to the horizontal advantage they observed (i.e., gaze path account). The present study tested competing predictions of these two accounts. Experiment 1 used vertically oriented flanker stimuli and compared the findings with Weidler et al. The LSPC effect was larger for vertically oriented stimuli on the vertical axis, and horizontally oriented stimuli on the horizontal axis, supporting the gaze path account. Experiment 2 used flanker stimuli that required participants to traverse through distracting flankers regardless of the axis on which stimuli were presented. The LSPC effect was equivalent between the vertical axis and horizontal axis conditions. These results further supported the gaze path account and suggest that the critical design feature for amplifying LSPC effects is not left/right locations per se, but rather use of stimuli/axis combinations that encourage processing of the distractor dimension.
人们会根据不同位置的冲突经历的历史来反应性地调整注意力控制，从而产生位置特异性比例兼容性 (LSPC) 效应。Weidler 等人（2022 年，《实验心理学杂志：人类感知与表现》，48[4]，312-330）发现，当刺激呈现在水平轴（即注视点左右的位置）上时，LSPC 效应比垂直轴（即注视点上下的位置）上更大。他们提出并提供了初步证据，表明左/右位置可能代表一个特殊的设计特征，导致更强的 LSPC 效应（即水平优先解释）。然而，他们使用水平定向的侧翼刺激，要求参与者穿越分心的侧翼，在水平轴条件下选择性地选择中央目标，这可能导致了他们观察到的水平优势（即注视路径解释）。本研究检验了这两个解释的竞争预测。实验 1 使用垂直定向的侧翼刺激，并将发现与 Weidler 等人的研究进行比较。在垂直轴上，LSPC 效应对于垂直定向的刺激更大，而在水平轴上，LSPC 效应对于水平定向的刺激更大，这支持了注视路径解释。实验 2 使用侧翼刺激，无论刺激呈现在哪个轴上，都要求参与者穿越分心的侧翼。LSPC 效应在垂直轴和水平轴条件之间相等。这些结果进一步支持了注视路径解释，并表明放大 LSPC 效应的关键设计特征不是左/右位置本身，而是使用鼓励处理干扰维度的刺激/轴组合。
