The influence of sex and housing conditions on outcomes of acquisition in social operant conditioning. Effects of experimental parameters of biological sex and housing conditions on social rewards (A), difference in active-inactive lever presses (B), latency to first active lever press (C), locomotor activity (D), within-session time course of mean social rewards averaged over sessions 7 and 8 (E), total time with nose in open door (F), proportion of open-door time with nose in door (G), within-session proportion of open-door time with nose in door averaged over sessions 7 and 8 (H), total time with nose in closed door (I), and proportion of closed-door time with nose in door (J). Sample sizes were n = 8 per factorial condition, except for locomotion, total time with nose in open door, total time with nose in closed door, and proportion of closed-door time with nose in door (F-Iso-L: n = 7, F-Pair-L: n = 7, F-Iso-D: n = 6, F-Pair-D: n = 6, M-Iso-L: n = 7, M-Pair-L: n = 8, M-Iso-D: n = 6, M-Pair-D: n = 6); and proportion of open-door time with nose in door (F-Iso-L: n = 7, F-Pair-L: n = 7, F-Iso-D: n = 6, F-Pair-D: n = 6, M-Iso-L: n = 6, M-Pair-L: n = 8, M-Iso-D: n = 6, M-Pair-D: n = 4). Data represent mean values ± S.E.M. and individual data points represent individual subject data. Statistical significance is indicated by the following: Sex– biological sex; H– housing condition; ToD– time-of-day; Ss– session, Time– timepoint during session. Level of statistical significance is indicated by the number of * symbols: one– p <.05, two– p <.01, three– p <.001
