Means and standard deviations for performance measures in the time estimation task.
| Time estimation | SDI |
Non-SDI |
|||
|---|---|---|---|---|---|
| Informative | Uninformative | Informative | Uninformative | ||
| Deviation from 1000 ms | Correct | 143 (65) | 146 (78) | 158 (76) | 154 (83) |
| Incorrect | 432 (137) | 425 (136) | 425 (168) | 432 (202) | |
| Post-feedback change | Correct | 167 (64) | 182 (83) | 157 (77) | 160 (60) |
| Incorrect | 225 (81) | 210 (71) | 231 (116) | 209 (143) | |
Deviation from 1000 ms and post-feedback change values are presented in milliseconds. Deviation scores represent the difference between the 1000 ms target estimation and the mean absolute value of deviations from 1 s. Post-feedback change scores represent the change in magnitude of deviation for trial n to n + 1. To compute change, the difference in the absolute value of the deviation from 1 s on trial (n) to the absolute value of the deviation from 1 s on trial (n + 1) was computed. Main effects for performance (i.e. Correct vs. Incorrect) were significant, but main effects for Feedback Type (Informative vs. Uninformative) and group (SDI vs. non-SDI) were not significant.
