Monkeys and humans ‘correlation between mean looking time and FWHR. Mean looking time in milliseconds (ms) of (a) monkeys (r(48) = −0.35, p < 0.05, Pearson correlation) and (b) humans (r(48) = −0.47, p < 0.001) are negatively correlated to the facial width height ratio (FWHR) scores, i.e., longer and narrower faces were looked longer by both species. Light grey points correspond to trustworthy faces and dark grey points to untrustworthy ones
