Deconstruction of prosocial behavior. (A) Test time (sec) spent allogrooming a same-sex, novel conspecific and (B) the number of play events exhibited did not differ between the age groups. (C) Pre-weaning (PND15) males spent significantly more time huddling with the stimulus male than PND45 and PND60, but not PND30, males. Box plots show the median (black line), 75th and 25th percentiles (box), and 95% confidence interval (whiskers). * represents extreme outliers. Letters above graphs (A, B) indicate statistical similarity.
