Immature grooming and playing with non-mothers in post-conflict versus non-conflict intervals from Limited evidence for third-party affiliation during development in wild chimpanzees (<i>Pan troglodytes schweinfurthii</i>)

Histogram of 10,000 proportions of non-conflict intervals in which an immature A) groomed or B) played with a non-mother obtained from a randomization procedure for individuals of age class 1.5 – 5.0, 5.0 – 8.0, 8.0 – 12.0. PC = Average proportion of PC intervals in which the non-mother was groomed or played with. NC = Bootstrapped mean of proportions in which the non-mother was groomed or played with in a random non-conflict interval.
