BALB/cJ (n = 12) and C57BL/6J (n = 12) test mice at ~30 days of age (range: 29 – 31 days of age) were tested for their tendency to approach and investigate a gonadectomized A/J stimulus mouse located in one chamber of a three-chambered apparatus. All results are displayed as M ± SEM. A) BALB/cJ mice approach the stimulus mouse less than C57BL/6J mice do, as measured by the chamber preference change score (t(22) = 3.27, p < 0.01, one-tailed). B) BALB/cJ mice investigate the stimulus mouse less than C57BL/6J mice do, as measured by the cylinder sniffing preference change score (t(22) = 6.71, p < 0.000001, one-tailed). C) BALB/cJ and C57BL/6J mice show no significant differences in their locomotor activity, regardless of whether the stimulus mouse is absent (first (Phase 1A) and second (Phase 1B) 5-minute blocks of the 10-minute acclimation period) or present (social choice period (Phase 2)). D) BALB/cJ and C57BL/6J mice show no significant differences in time spent sniffing a novel object (paperweight) during Phase 2.
