Variance decomposition of resting-state cognition in fMRI group (n = 68).
| Sum of squares (%) | ||||
|---|---|---|---|---|
| Factor | Between individuals | Resting-state block (within) | Residual (within) | Total |
| Discontinuity of mind | 62.1 (78.4) | 1.4 (1.8) | 15.7 (19.8) | 79.3 (100) |
| Theory of mind | 106.8 (75.7) | 0.1 (0.1) | 34.0 (24.2) | 140.9 (100) |
| Self | 71.3 (78.2) | 0.00 (0) | 19.9 (21.8) | 91.2 (100) |
| Planning | 74.5 (84.2) | 0.03 (0.0) | 14.0 (15.8) | 88.5 (100) |
| Sleepiness | 90.4 (75.5) | 0.8 (0.7) | 28.5 (23.8) | 119.7 (100) |
| Somatic awareness | 73.0 (83.4) | 1.4 (1.6) | 13.1 (15.0) | 87.6 (100) |
| Comfort | 122.5 (76.8) | 4.1 (2.6) | 32.9 (20.6) | 159.6 (100) |
Most of the variance in the scores over the two resting-state blocks is due to between-subject variability. Repeated-measures ANOVA sum of squares contribution of inter-individual and intra-individual variability for each resting-state cognition factor mean score. Variance is divided into between-subjects variability and within-subject variability, with the latter subdivided into the effect of the resting-state block and residual variability. Percentages are fractions of total sum of squares.
