Age (years)	27.9 ± 3.6	29.6 ± 3.6	0.000
Education (years)	14.8 ± 1.9	15.0 ± 1.8	0.132
AUC$200	0.275 ± 0.217	0.256 ± 0.191	0.079
AUC$40K	0.542 ± 0.282	0.514 ± 0.283	0.403
AUC$40K—AUC$200	0.249 ± 0.211	0.258 ± 0.216	0.566
RT_REW (ms)	404.8 ± 118.4	432.6 ± 106.4	0.000

Note: Values are mean ± SD; AUC, area under the curve; RT_REW: RT of reward block; RT_PUN: RT of punishment block. The RT data were missing in a total of 96 subjects (30 women) from the HCP; thus, 872 subjects (472 women) were included in the RT statistics.
