人类是社会性动物，经常与他人交往。社会思想和行动的重要性怎么强调都不过分。然而，社会信息是否如此重要，以至于它实际上决定了哪些刺激被提升为意识体验，哪些刺激被抑制为不可见？为了解决这个问题，我们使用了双眼竞争范式，其中两只眼睛接收不同的动作刺激。在两个实验中，我们测量了对手行为的有意识感知，发现参与社会互动的行为比非互动行为更容易获得视觉感知。最后，一个可能参与心智化系统的注意力任务，在达到有意识的知觉时，提高了社会互动的优先级。我们还发现，人类识别的互动活动和促进社会相关信息的视觉意识之间的正相关关系。目前的研究结果表明，视觉系统放大了与社会相关的感官信息，并积极地将其提升到意识中，从而促进了对社会互动的推断。
Humans are social animals, constantly engaged with other people. The importance of social thought and action is hard to overstate. However, is social information so important that it actually determines which stimuli are promoted to conscious experience and which stimuli are suppressed as invisible? To address this question, we used a binocular rivalry paradigm, in which the two eyes receive different action stimuli. In two experiments we measured the conscious percept of rival actions and found that actions engaged in social interactions are granted preferential access to visual awareness over non-interactive actions. Lastly, an attentional task that presumably engaged the mentalizing system enhanced the priority assigned to social interactions in reaching conscious perception. We also found a positive correlation between human identification of interactive activity and the promotion of socially-relevant information to visual awareness. The present findings suggest that the visual system amplifies socially-relevant sensory information and actively promotes it to consciousness, thereby facilitating inferences about social interactions.
