Previous studies investigating the ability of high priority stimuli to grab attention reached contradictory outcomes. The present study used eye tracking to examine the effect of the presence of the self-face among other faces in a visual search task in which the face identity was task-irrelevant. We assessed whether the self-face (1) received prioritized selection (2) caused a difficulty to disengage attention, and (3) whether its status as target or distractor had a differential effect. We included another highly familiar face to control whether possible effects were self-face specific or could be explained by high familiarity. We found that the self-face interfered with the search task. This was not due to a prioritized processing but rather to a difficulty to disengage attention. Crucially, this effect seemed due to the self-face's familiarity, as similar results were obtained with the other familiar face, and was modulated by the status of the face since it was stronger for targets than for distractors.
以往研究高优先级刺激吸引注意力能力的结果相互矛盾。本研究采用眼动追踪技术,在面部身份与任务无关的视觉搜索任务中,考察自我面孔在其他面孔中出现时的影响。我们评估了自我面孔是否(1)得到优先选择,(2)导致注意力难以脱离,以及(3)其作为目标或干扰项的状态是否有不同影响。我们纳入了另一张高度熟悉的面孔,以控制可能的效应是自我面孔特有的,还是可以用高度熟悉来解释。我们发现自我面孔干扰了搜索任务。这并非由于优先加工,而是由于注意力难以脱离。至关重要的是,这种效应似乎是由于自我面孔的熟悉度,因为另一张熟悉面孔也得到了类似结果,并且这种效应受面孔状态的调节,因为对目标的影响比对干扰项的影响更强。
