我们分析了灵长类社会中冲突决策的时间尺度。我们提供了与社会决策和行为模式相关的多个周期性时间尺度的证据。我们证明了周期性的存在，这些周期性与环境循环或已知的超纬度机制不直接相关。在特定的生物学和社会定义的人口类别中，周期性跨越几小时到几天的时间尺度。我们的结果表明，这些周期性不是由外生或内部规律驱动的，而是由对社会互动模式的战略反应驱动的。分析还表明，扮演关键职能角色（治安）的一类个人的签名时间尺度约为 1 小时。我们提出了一种类似于神经系统的行为时间尺度的分类，从一小时尺度上发生的高频或阿尔法尺度行为，到多小时或贝塔尺度行为，最后是在天的时间尺度上观察到的伽玛周期性。
We analyse the timescales of conflict decision-making in a primate society. We present evidence for multiple, periodic timescales associated with social decision-making and behavioural patterns. We demonstrate the existence of periodicities that are not directly coupled to environmental cycles or known ultraridian mechanisms. Among specific biological and socially defined demographic classes, periodicities span timescales between hours and days. Our results indicate that these periodicities are not driven by exogenous or internal regularities but are instead driven by strategic responses to social interaction patterns. Analyses also reveal that a class of individuals, playing a critical functional role, policing, have a signature timescale of the order of 1 h. We propose a classification of behavioural time-scales analogous to those of the nervous system, with high frequency, or alpha-scale, behaviour occurring on hour-long scales, through to multi-hour, or beta-scale, behaviour, and, finally gamma periodicities observed on a timescale of days.
