Septal injections of a V1aR antagonist enhanced duration of social play (A), number of nape attacks (D), and number of pins (E) in juvenile male rats but reduced these parameters in juvenile female rats (F2,34=9.39, p < 0.005, F2,34=5.82, p < 0.01 and F2,34=12.2, p < 0.001, respectively). Social play, social investigation (B), and non-social exploration (C) are expressed as percentage of total time. Bars indicate means + SEM. *: p < 0.05, **: p < 0.01, *** p < 0.005, **** p < 0.001, #: p < 0.05 versus male counterparts; Bonferroni post hoc tests.
