For a description of the task see Methods. Comparisons of prosopagnosic cases with control group were calculated by z-scores.
*, P < 0.05;
†, P < 0.01;
‡, P < 0.001.
Control group: Warrington Face Memory, n = 25 (18–27 yr); faces and shoes, n = 11 (18–28 yr); face and house parts, n = 21 (18–29 yr). Maximum possible score for Benton Face Recognition was 54, for Warrington Face Memory 50, and for the other tests 64.
