No other spectral power comparisons yielded statistically significant results; but there was a statistical trend suggesting inaccuracy was associated with reduced alpha (8 Hz) power over posterior sensors ( T = 4.61, p FWE = 0.069).

Tentatively, this interpretation is supported by the fact that posterior alpha power behaved opposite to gamma (i.e., it decreased with increasing inaccuracy, although this effect did not reach statistical significance; see Results).
