N2c and P3a at midline electrodes. The grand-average N2c and P3a at Fz (left panel), Cz (central panel) and Pz (right panel) evoked by the non-targets C+F-, C-F+, and C-F-. Top panel. The color-overlap distractor (C+F-) elicited a distinct N2c at Fz as well as a distinct P3a at Cz, compared with the evoked response of the other two non-targets (i.e., the form-overlap distractor (C-F+) and the standard non-target (C-F-), respectively) when colors were easily distinguishable (easy distinctiveness condition). Middle panel. Similar effects were observed when the perceptual distinctiveness of colors was at an intermediate level. Bottom panel. The color-overlap distractor (C+F-) neither elicited a distinct N2c at Fz nor a distinct P3a at Cz, compared with the evoked response of the other two non-targets (i.e., the form-overlap distractor (C-F+) and the standard non-target (C-F-), respectively) when the colors were hard to distinguish (hard distinctiveness condition).
