众所周知，注视某人突然移动眼睛会引发观察者相应的注意力转移。这种现象，被称为凝视暗示效应，可以作为暗示面孔中描绘的个体的社会地位的函数来调节。在这里，在两个实验中，我们研究了这种调制的时间动态。为此，实施凝视线索范式，其中中央放置的脸描绘高和低地位的个人突然转移到一个位置的眼睛空间一致或不一致的后续目标刺激所占据的。在实验阶段之前，社会地位被操纵，呈现虚构的简历。在实验1中，其中两个时间间隔（50毫秒与900毫秒）之间发生的直接凝视脸和回避凝视脸的发作，一个更强的凝视提示效果，在响应高地位的面孔比低地位的面孔被观察到，无论时间参与者被允许提取社会信息。在实验2中，其中两个时间间隔（200毫秒与1000毫秒）之间发生的回避凝视脸和目标发病，一个更强的凝视提示高地位的面孔，观察到在较短的时间间隔。两者合计，这些结果表明，有关社会地位的信息提取迅速（实验1），并有选择性地参加高地位的个人注视的位置的趋势可能会随着时间的推移衰减（实验2）。
Fixating someone suddenly moving the eyes is known to trigger a corresponding shift of attention in the observer. This phenomenon, known as gaze-cueing effect, can be modulated as a function of the social status of the individual depicted in the cueing face. Here, in two experiments, we investigated the temporal dynamics underlying this modulation. To this end, a gaze-cueing paradigm was implemented in which centrally-placed faces depicting high- and low-status individuals suddenly shifted the eyes towards a location either spatially congruent or incongruent with that occupied by a subsequent target stimulus. Social status was manipulated by presenting fictive Curriculum Vitae before the experimental phase. In Experiment 1, in which two temporal intervals (50 ms vs. 900 ms) occurred between the direct-gaze face and the averted-gaze face onsets, a stronger gaze-cueing effect in response to high-status faces than low-status faces was observed, irrespective of the time participants were allowed for extracting social information. In Experiment 2, in which two temporal intervals (200 ms vs. 1000 ms) occurred between the averted-gaze face and target onset, a stronger gaze cueing for high-status faces was observed at the shorter interval only. Taken together, these results suggest that information regarding social status is extracted from faces rapidly (Experiment 1), and that the tendency to selectively attend to the locations gazed by high-status individuals may decay with time (Experiment 2).
