experiment 2. A: trial schematics for “same location” trial. B: ERP data from trials in which 4 items were remembered sequentially, either at the same location (red) or different location (blue) as the 1st memory array. Time-locked to the onset of memory array 1. C: CDA amplitudes 300–500 ms following the 1st and 2nd memory array. Mean CDA amplitudes from simultaneous 2- and 4-item conditions are shown in dashed lines. Error bars = 95% confidence intervals. Significant main effect of time window was found (1st delay vs. 2nd delay, P < 0.001), but no effect of locations was found. Regardless of the location, CDA amplitude after the second delay was statistically not different from simultaneous presentation of 4 items.
