Summary of conflict decision-making timescales detected in the study group. Detections in the various bands (α, β and γ) are shown for the two null models. In addition, we show the overall significance of the detections. The primary timescales found are α (between 30 min and 2 h) and γ (above 6 h). One demographic class the second power quartile, shows a significant intermediate, β, scale between 2 and 6 h. Taken collectively, the 47 socially mature individuals, as well as a number of smaller demographic classes, show significant evidence overall for non-stationary behaviour (above the mixed-strategy null); overall violations of the daily-forcing null, indicating fluctuation-sensitive behaviour, are rarer and found in only in the adult males and in the policing class. In the 11 matrilines, there are two detections of α- and β-scales; only one matriline has an overall significance against the mixed-strategy null (p = 0.003.)
