Cond = condition (deviant vs standard); Reg = region; Fron = frontal; Cen = central; Pos = posterior; Site = electrode site; Hem = hemisphere.

Note that only statistically significant effects are reported.

^aThe interaction Cond × Region × Spelling Group F(2,88) = 4.72 did not reveal any significant step-down results involving the factor spelling group and was thus disregarded.
