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.
