Mean, SD, and P values (two-tailed Wilcoxon signed rank test) for within-subject correlations (n = 28) of RT CoV with off-task rating and with DMN signal in 30-s prerating periods
| Correlation | r, mean ± SD | P |
| Off-task rating vs. prerating RT CoV | 0.18 ± 0.23 | 0.001 |
| Prerating DMN activity vs. RT CoV | −0.13 ± 0.17 | 0.0014 |
Before Wilcoxon signed rank tests, within-subject Pearson’s r values were Fisher-transformed to z values.
