General linear mixed model (GLMM) output showing fixed effects with response as proportion of scolding. Age and time since training were z-transformed, the rest dummy coded with the reference categories being neutral (for mask), first presentation (for order), 1 (for sib-group), and hand-raised (for raising). Higher sex ratios indicate more males. N = 722. Significance codes: <0.1; * < 0.05; ** < 0.01; *** < 0.001.
