Within‐brain coupling
LME, FM
To examine whether participants exhibit differences in within‐brain coupling between the various task conditions, we constructed two LME models, which included Condition (BB, FM, and IS), and ROI pairings as fixed factors, dyads' ID numbers as a random factor, and coherence (WTC) values as a dependent measure. The first included only the main effects of the fixed factors, while the second model included a possible interaction between them as well.
