Sample A (Table 1): performance of females (white) and males (black) on the Freiburg visual acuity test (a), vernier discrimination (b), adding the 25 elements mask (SOA25) (c) or the 5 elements mask (SOA5) (d). Females have significantly lower visual acuity on The Freiburg visual acuity task compared to males and needed significantly longer SOAs between the vernier and the mask in order to show 75% accuracy rate. The effect size was medium for visual acuity and small for the remaining two significant tests. Error bars represent ± 2 SE of the mean. *p < 0.05, ***p < 0.001.
