PSYCHOLOGICAL AND COGNITIVE SCIENCES Correction for “Testosterone administration impairs cognitive empathy in women depending on second-to-fourth digit ratio,” by Jack van Honk, Dennis J. Schutter, Peter A. Bos, Anne-Wil Kruijt, Eef G. Lentjes, and Simon Baron-Cohen, which appeared in issue 8, February 22, 2011, of Proc Natl Acad Sci USA (108:3448–3452; first published February 7, 2011; 10.1073/pnas.1011891108).

(A) Effect of testosterone administration on cognitive empathy in young women: mean and SEM of the percentage correct responses on the RMET after administration of testosterone and placebo (P = 0.013, one-tailed). Testosterone administration impairs the ability to accurately infer motives, intentions, thoughts, and emotions from the eye region of the face of others. (B) Fetal testosterone exposure (inferred from 2D:4D ratio) predicts the effect of testosterone administration on cognitive empathy: scatter plot shows the interaction between the 2D:4D ratio fetal testosterone marker and the effect of testosterone (T) administration on cognitive empathy (P < 0.001). The group effect of testosterone administration on cognitive empathy varies strongly according to individual 2D:4D ratios. The asterisk defines two identical data points. (C) Effect of testosterone (T) administration on cognitive empathy in subjects with high and low fetal testosterone exposure (inferred 2D:4D ratio): Mean and SEM of the effect of testosterone administration on cognitive empathy in subjects with relatively low and high 2D:4D ratios, based on median split. Substantial effects of testosterone on cognitive empathy are observed in subjects with high fetal testosterone exposure (P = 0.006, one-tailed), and no effects are seen in subjects with low fetal testosterone exposure (P = 1).]
