ERP results across memory conditions. (A) Grand-averaged waveforms (averaged across PO7/8 and P7/8 electrodes) for the three memory array conditions: all-different (blue), partial-same (orange), and all-same (gray). The waveforms reflect lateralized activity (contralateral minus ipsilateral) and are time-locked to the onset of the memory array (time zero on the x-axis). The shaded gray area indicates the duration of memory array presentation. Dashed rectangles highlight the predefined time windows for the early and late CDA components. (B) Mean CDA amplitudes during the early time window (500–650 ms) for each memory condition (all-different condition, partial-same condition, and all-same condition). (C) Mean CDA amplitudes during the late time window (700–850 ms) for each memory condition. Error bars indicate SE. ** = p < .01, * = p < .05, N.S. = p > .05.
