marginally significantP = 0.056
Post hoc tests showed this interaction was driven by a marginally significant difference between high- and low-frequency items at left electrodes ( P = 0.056, Mhigh = −1.57 (SE = 0.04), Mlow = −1.98 (SE = 0.04)), and a significant increase from right to left electrodes for high-frequency items ( P < 0.001, Mright = −1.7 (SE = 0.04), diff = 0.13 mV), which was absent for low-frequency items ( P = 0.998, Mright = −1.9 (SE = 0.04), diff = 0.08 mV).
