Table S1. The results of two two-way analyses of variance with activity exhibited in the B-tests
at Stage 1 of focal offspring as dependent variable, Category as within-subject variable, and
either the presence of older offspring (two levels: yes/no) or mother’s reproductive state at Stage
1 (two levels: reproductive/ nonreproductive) as between-subject variables (BV). Females were
considered reproductive if pregnant or/and lactating.
