个体之间凝视的动态交互是社会认知的标志。然而，很少有研究探讨了实时交互过程中相互目光接触后的社会注视动态。我们使用了一个高度可量化的范式来评估成对猴子之间的社会凝视动态，并使用指数衰减函数来模拟这些动态，以研究相互眼神接触后的持续注意力。当猴子与真实的伙伴互动时，与同一只猴子的静态图像和电影相比，我们发现眼睛注视的比例显着增加，眼睛周围的注视分散度较小，这表明对眼睛区域的焦点注意力增强。值得注意的是，互动对之间的优势和熟悉感引起了可分离的凝视动态组件，这是现场互动所独有的。相互目光接触后占主导地位的猴子的凝视动态与更多的固定到眼睛，而熟悉的对与更快的速度下降，在这个眼睛导向的注意。我们的研究结果支持这样一种观点，即社会认知的某些关键方面只在互动的社会环境中被捕获，并依赖于与社会有意义的事件相关的时间。
The dynamic interaction of gaze between individuals is a hallmark of social cognition. However, very few studies have examined social gaze dynamics after mutual eye contact during real-time interactions. We used a highly quantifiable paradigm to assess social gaze dynamics between pairs of monkeys and modeled these dynamics using an exponential decay function to investigate sustained attention after mutual eye contact. When monkeys were interacting with real partners compared with static images and movies of the same monkeys, we found a significant increase in the proportion of fixations to the eyes and a smaller dispersion of fixations around the eyes, indicating enhanced focal attention to the eye region. Notably, dominance and familiarity between the interacting pairs induced separable components of gaze dynamics that were unique to live interactions. Gaze dynamics of dominant monkeys after mutual eye contact were associated with a greater number of fixations to the eyes, whereas those of familiar pairs were associated with a faster rate of decrease in this eye-directed attention. Our findings endorse the notion that certain key aspects of social cognition are only captured during interactive social contexts and dependent on the elapsed time relative to socially meaningful events.
