Bar graphs and scatterplots showing the relationship between the face ratio judgements of aggression.

<p><b>A</b> The mean Fisher's Z correlations between observers' judgements of aggression and the face ratio in Study 1, for male (n = 24) and female faces (n = 31), and, in Study 2 (shaded area), for female faces (n = 31). Error bars represent the standard error. * male faces > female faces, p<0.05. <b>B</b> The percent of observers whose judgements of aggression were correlated significantly with the face ratios of male (n = 24) and female faces (n = 31) in Study 1, and female faces (n = 31) in Study 2 (shaded area). <b>C</b> Scatterplot of the face ratio and judgements of aggression in male (n = 24) and female faces (n = 31) in Study 1. <b>D</b> Scatterplot of the face ratio and judgements of aggression in female faces (n = 31) in Study 2.
