Numbers refer to the beginning and the end of the study. Following Schiel and Huber (2006), we assigned the individuals to four different age categories (adults/subadults: >11 months; juveniles: 5–10 months; older infants: 3–4 months; young infants: 0–2 months). N (max) indicates the total number of the individuals belonging to each group during the whole experiment). Note that the number of monkeys per group varied across the different sessions and test blocks, mainly because of births (>50), deaths, disappearances or emigration to other groups.
