Table 4. Mixed-effects analysis of resting state and task data before and following task switches (R1, T1, T5 and R2): Effects of task switch (RS vs. task period), time point (data at the first switch vs. the second) and task switch-by-time point interaction on (i) mean connectivity strength, (ii) functional network and (iii) physical distance metrics.
Response | Factor | Statistics |
Connectivity Strength(a) | Task switch (RS to task, or task to RS period) | F(1,57) = 0.05, p = 0.83 |
