Fig. 3: Role model choices as developmental stage, food processing complexity, and party size change.

A Effect of age on the probability of peering at other individuals than the mother (model 3a). B Interaction between party size and food processing complexity on the probability of peering at other individuals while at least one individual (the mother) is foraging (model 3b). The regression lines from the Bayesian Regression model show a 95% credible interval. Each dot represents the number of peering events per subject and age in a month: (A), per individual, type of foraging, and party size (B).
