bottom left panel) emerged early ~50-150 ms and 4-5 Hz. Pairwise comparisons suggest this effect mainly reflected greater spectral power for the 13-14-year-old group compared to the 15-17 year-old group (p = .010, Figure 4C) and the 10-12-year-old group (trend, p = .091). The second effect (ERSP Age Effect 2, p = .036, Figure 4D, bottom right panel).) appeared in the window of 4-6 Hz and 300-400 ms. This effect mainly reflected that the 13-14-year-old group had more spectral power in the 4-6 Hz range than the 10-12-year-old group, p = .006 (Figure 4D). The 15-17-year old group had less power in this range than the 13-14-year old group (trend, p = .075).
