注视方向可以用于快速和反射性地引导或误导他人对重要刺激的位置的注意。当注视方向的感知与目标的位置一致时，与不一致时相比，反应更快。那些一直注视一致的面孔也比那些一直注视不一致的面孔更值得信赖。然而，目前还不清楚凝视线索如何引起信任的变化。我们测量了面部肌电图（EMG）在身份相依凝视线索任务，以检查是否体现情绪反应凝视线索介导的信任学习。无论参与者是否在预期的方向上表现出信任的学习，凝视提示效应都是等效的。相比之下，我们发现这两个人群的EMG活动模式明显不同。在进一步的实验中，我们发现学习效果是特定于观看面部的，因为当观看引起类似注意定向反应的箭头时，没有检测到喜欢的变化。这些研究结果表明，在学习信任的身份-特遣队凝视提示，可能是由于共享的注意力或欺骗，而不是域一般的注意力定向的社会价值体现的情绪。
Gaze direction can be used to rapidly and reflexively lead or mislead others’ attention as to the location of important stimuli. When perception of gaze direction is congruent with the location of a target, responses are faster compared to when incongruent. Faces that consistently gaze congruently are also judged more trustworthy than faces that consistently gaze incongruently. However, it’s unclear how gaze-cues elicit changes in trust. We measured facial electromyography (EMG) during an identity-contingent gaze-cueing task to examine whether embodied emotional reactions to gaze-cues mediate trust learning. Gaze-cueing effects were found to be equivalent regardless of whether participants showed learning of trust in the expected direction or did not. In contrast, we found distinctly different patterns of EMG activity in these two populations. In a further experiment we showed the learning effects were specific to viewing faces, as no changes in liking were detected when viewing arrows that evoked similar attentional orienting responses. These findings implicate embodied emotion in learning trust from identity-contingent gaze-cueing, possibly due to the social value of shared attention or deception rather than domain-general attentional orienting.
