(a) Frequency distributions for the VFMT-White and VFMT-East Asian with best Gaussian fits to the data of 120 individuals. X axis indicates the number of correct trials, with chance level = 16 (i.e., 33.3% correct), and the maximum number of correct trials = 48(i.e., 100% correct). Y axis indicates the number of people that got the corresponding number of trials correct) (b) Average cumulative scores across 48 test items for White faces and Asian faces. The red diagonal lines indicate perfect performance (100% accuracy), and the blue dots indicate the average cumulative score at each test item, representing participants’ actual performance. Error bars indicate the standard deviation for the cumulative scores. The task is divided into two stages, with the first 18 items in the Identical-Image Stage, and last 30 items in the Novel-Image Stage.
