When EEG and task predictors were included together, both remained highly significant ( p < 0.001), and model fit improved (R 2 ≈ 1.000) for all regions.

However, pairwise comparisons revealed a near-significant trend in the alpha band between Focused and Rest conditions [ t (6) = −2.15, p = 0.075], suggesting that phase alignment may be more consistent during focused attention ( Table 6 ).
