In two experiments we examined whether the allocation of attention in natural scene viewing is influenced by the gaze cues (head and eye direction) of an individual appearing in the scene. Each experiment employed a variant of the flicker paradigm in which alternating versions of a scene and a modified version of that scene were separated by a brief blank field. In Experiment 1, participants were able to detect the change made to the scene sooner when an individual appearing in the scene was gazing at the changing object than when the individual was absent, gazing straight ahead, or gazing at a nonchanging object. In addition, participants' ability to detect change deteriorated linearly as the changing object was located progressively further from the line of regard of the gazer. Experiment 2 replicated this change detection advantage of gaze-cued objects in a modified procedure using more critical scenes, a forced-choice change/no-change decision, and accuracy as the dependent variable. These findings establish that in the perception of static natural scenes and in a change detection task, attention is preferentially allocated to objects that are the target of another's social attention.
在两项实验中，我们研究了在自然场景观看中注意力的分配是否会受到场景中出现的个体的注视线索（头部和眼睛方向）的影响。每个实验都采用了闪烁范式的变体，其中场景的交替版本和该场景的修改版本由一个短暂的空白区域隔开。在实验1中，当场景中出现的个体注视变化的物体时，参与者比个体不在场、直视前方或注视不变物体时，能更快地检测到场景中的变化。此外，随着变化的物体离注视者的视线越来越远，参与者检测变化的能力呈线性下降。实验2在一个修改后的程序中重复了注视线索物体的这种变化检测优势，该程序使用了更关键的场景、强制选择变化/无变化决策，并将准确性作为因变量。这些发现表明，在静态自然场景的感知和变化检测任务中，注意力会优先分配到他人社会关注目标的物体上。
