Time–frequency analysis (TFA) on ERPs. Significant differences between MWA and MWoA are marked by black rectangles: only frequencies in the lower range (below 8 Hz) are reported. These time–frequency windows are numbered with a practical aim for further description, i.e. TF-1…TF-11 (Table 2). Maps represent frequencies across time, time-point 0 being the stimulus onset (vertical dashed line). Color scales express the power (µV2/Hz) and are normalized across groups and stimuli. The data was taken from Pz electrode. Choc: Chocolate, L: left, R: right
