Table 2 appears incorrectly in the published article. Please see the correct Table 2 and its caption here.

Table 2

Mean performance on the stop-signal task in normal controls, ARMS subjects and schizophrenia patients; these means were examined using ANOVAs.

	Control(n = 38)	ARMS(n = 27)	Schizophrenia(n = 37)	Statistics
				F	P
IIV stop	19.04(17.32)	38.70(28.54)	36.90(24.79)	7.57	0.001 a,b
IIV go	87.79 (59.28)	154.65(96.11)	132.06(72.99)	6.78	0.002 a,b
SSRT	159.46(48.17)	216.01(108.02)	231.11(127.90)	5.32	0.006 a,b
Go RT	459.65(143.20)	561.01(173.93)	547.82(152.18)	4.42	0.015 a
PSS	0.51(0.09)	0.55(0.16)	0.54(0.16)	0.65	0.524

Note. Data are presented as the means (SD). ARMS = at-risk mental state; IIV = intra-individual variability; SSRT = stop-signal reaction rime; Go RT = reaction time on go trials; PSS = proportion of successful stops.

a p < 0.05 for two-tailed tests.

b p < 0.01 adjusted significance for two-tailed tests with application of Bonferroni correction for multiple comparisons.
