Temporal binding (TB) refers to an underestimation of time intervals between two events, most commonly for actions and their effects. This temporal contraction is measurable for both perceived changes in social stimuli such as faces, as well as for interactions with a partner. We investigated TB in two separate experiments to uncover the individual influences of (i) participants’ belief in an interaction with a human partner (as compared to a computer), and (ii) a face-like stimulus versus an abstract stimulus mediating the interaction. The results show that TB is more pronounced when self-initiated actions result in a personal event as opposed to a mere physical effect, being suggestive of a “social hyperbinding.” The social hyperbinding effect appeared to be driven both by the belief in interacting with another person and by a face-like stimulus. However, there seemed to be no further enhancing effect when combining the top-down processes (“beliefs”) with the bottom-up processes (“perceptions”). These findings suggest a prioritization of social information for TB regardless of whether this information is introduced by top-down (beliefs) or bottom-up information (stimuli). Our results add to existing literature demonstrating an increase in action-event monitoring for social cues.

时间约束 (TB) 是指低估两个事件之间的时间间隔，最常见的是动作及其影响。这种时间收缩对于诸如面部等社会刺激的感知变化以及与伴侣的互动都是可测量的。我们在两个独立的实验中研究了结核病，以揭示（i）参与者对与人类伴侣互动的信念（与计算机相比）以及（ii）面部刺激与介导互动的抽象刺激的个体影响. 结果表明，当自我发起的行为导致个人事件而不是单纯的身体影响时，结核病会更加明显，这暗示着“社会过度绑定”。社会超绑定效应似乎是由与另一个人互动的信念和类似面孔的刺激所驱动的。然而，当将自上而下的过程（“信念”）与自下而上的过程（“感知”）结合起来时，似乎没有进一步的增强效果。这些研究结果表明，无论这些信息是由自上而下（信念）还是自下而上信息（刺激）引入，都应优先考虑结核病的社会信息。我们的结果增加了现有的文献，表明对社会线索的行动事件监测有所增加。
