Latency to enter the threat zone does not affect body weight gain, saccharin preference, or open field activity. a Body weight (g) increased in all groups from baseline (BL), through the 3 weeks of social defeat stress, to 1 week post-stress (PS), although overall, “fast” (black circles, n = 13) rats weighed significantly less than “slow” (gray circles, n = 13) and control (white circles, n = 43) rats (*p < 0.05). b Percent change in body weight from baseline (%BL) did not differ between groups. c Saccharin intake (mg/kg body weight) increased from BL to the 1 week PS in all groups, but no differences in saccharin consumption between groups were observed. d Saccharin preference (%, saccharin intake/(saccharin intake + water intake) also did not differ between groups. e On the first day of baseline open field testing, distance traveled (cm) in 5 min bins decreased across the 30-min habituation period but did not differ between groups. Insertion of a novel object (N) into the open field caused increased locomotor activity, but distance traveled did not differ between groups. f Average locomotor activity at BL, during each of the 3 weeks of stress, or PS did not differ across groups.
