MANCOVA results for behavioral measures for Rapid-response impulsivity and Reward-delay impulsivity combined group: Presented are raw Means (standard deviations) and F-statistic.
| Variable | Low impulsivity group (n = 22) | High impulsivity group (n = 23) | F(1,42) | Partial Eta Squared |
|---|---|---|---|---|
| GNGT – number of commission errors | 2.50 (2.3) | 5.17 (4.5) | 7.50∗∗ | 0.15 |
| GNGT – Mean RT | 357.01 (51.5) | 388.19 (76.6) | 2.74 | 0.6 |
| SST – number of commission errors | 9.73 (7.1) | 15.91 (10.3) | 5.95∗ | 0.12 |
| SSRT | 307.99 (173.7) | 279.86 (147.4) | 0.38 | 0.01 |
| DDT | 0.49 (0.2) | 0.62 (0.1) | 8.76∗∗ | 0.17 |
For the DDT, the proportion of small-immediate/large-delayed reward choices is shown. GNGT, Go/No-Go Task; RT, reaction time; SST, Stop-Signal Task; SSRT, Stop-Signal reaction time; DDT, Delay Discounting Task. ∗p < 0.05, ∗∗p < 0.01.
