Meaningful Gesture in Monkeys? Investigating whether Mandrills Create Social Culture
Figure 3
Individuals experience significantly reduced disturbance while gesturing.
Disturbance rates (per h) when mandrills were and were not gesturing. Periods of non-gesturing represented controls in which the same individuals were in a stationary resting context with either a lying or sitting body posture, but were not covering their eyes. (A) Approach rate (others coming within 2 m of the focal individual). (B) Touch rate (others initiating tactile contact with the focal individual). Mean + SEM shown. See Tables S4 and S5 for data on each individual separately.
