Examples of the different types of trial.
Fig 2.
Mean reaction times (RTs) as a function of perceptual load and validity when the cue was held in WM and when it was merely identified.
*p < .05, **p < .01, ***p < .001.
Fig 3.
The validity effects on the P1 and N1 component under the low perceptual load (upper panels) and the high perceptual load (lower panels) conditions when the cue was held in WM (left panels) and when it was merely identified (right panels).
Data were also averaged across memory-matching stimuli at ipsilateral vs. contralateral electrode sites. The left occipito-parietal electrodes include O1, PO3 and PO7 and the right occipito-parietal electrodes include O2, PO4 and PO8.
Fig 4.
The mean amplitude for the P1 (A and B) and N1 component (C and D) as a function of perceptual load and validity of the stimuli across WM group and priming group.
The representative electrodes for P1 and N1 component were O1, PO3, PO7, O2, PO4, and PO8.
Fig 5.
The scalp voltage distribution maps of the P1 (upper panels) and N1 (lower panels) component as a function of perceptual load and validity when the cue was held in WM (left column) and when it was merely identified (right column).
The time points of the P1 and N1 components were 80–120 ms and 150–190 ms both in the WM group and the mere-repeat group, respectively. The color bars show the voltage value (in μV) of the component.

Displays grand mean sLORETA images of P1 (80–120 ms) and N1 (150–190 ms) for the four conditions in the WM group.
Color bars represent voxel current density values (A/m2).
