Challenging the contest vs. scramble dichotomy in social competition: mixed conditions allow disparately ranked monkeys to get equivalent food but experiencing more competition still leads to risk-averse decisions.

An ANOVA comparing the GLMM version of the more complex First Choice of Platforms Model (with previous experience as focal in the current study, proportion of trials where the focal encountered a dominant competitor, presence of a dominant competitor within 25 m included as fixed effects, and identity of the focal individual included as a random effect) with a null model using only the focal’s identity (included as a random effect) as a predictor, found differences between the models that approached significance based on a likelihood ratio test ( P = 0.059), and an increase in deviance of 7.428, suggesting that the First Choice of Platforms Model had a better fit than did the null model.
