RT incorrect delayed red X ms	551	23	562	26	548	17	1.25	0.298
Discriminability red X	0.72	0.10	0.71	0.09	0.78	0.06	2.52	0.097
Bias red X	−0.14	0.13	−0.17	0.08	−0.10	0.14	1.01	0.377
Discriminability non-X	0.84	0.05	0.84	0.04	0.86	0.04	1.01	0.375

^†Repeated measures ANOVA revealed a significant main effect of trial time for red X (F = 15, P ≤ 0.001) trials. There were no between group differences across trial time (group × time F = 0.9, P = 0.42).

^‡Repeated measures ANOVA revealed a significant main effect of trial time for blue X (F = 37, P ≤ 0.001) trials. There were no between group differences across trial time (group × time F = 1.0, P = 0.39).

ADHD, attention-deficit hyperactivity disorder; BPD, bipolar disorder; SD, standard deviation.
