Evoked potentials at Fz-electrode position is shown for #-items. Solid lines represent disconfirming and dashed lines confirming #-items. Those #-items following K-items are shown in black and #-items with T-item as predecessor are depicted in grey. The underlying grey box shows the latency range of noise-replacement. The starred range depicts the analyzed time course as identified by the permutation tests for the induced GBA.
