“Empathy and pro-social behavior in rats” by I. B.-A. Bartal et al. (9 December 2011, p. 1427). On p. 1428, the last full paragraph of column 1 was incorrect. The paragraph should be replaced by this corrected text: “All female rats (6/6) and most male rats (17/24) in the trapped condition became door-openers. Female rats in the trapped condition opened the restrainer door at a shorter latency than males on days 7 to 12 (P < 0.01, MMA, Fig. 3A), consistent with suggestions that females are more empathic than males (7, 12, 13). Furthermore, female rats were also more active than males in the trapped condition (P < 0.001, ANOVA) but not in the empty condition (Fig. 3B).”
