Fig. 3.

P2 repetition effects at each lag, for RVF/LH-studied hits (first row) and LVF/RH-studied hits (second row). Effects are shown at the right medial frontal electrode site (RMFr), where P2 effects are prominent, with an abbreviated timescale (100 ms pre-stimulus to 500 ms post-stimulus onset). For RVF/LH-studied test words, P2 responses to hits and correct rejections did not differ at any lag. For LVF/RH-studied test words, in contrast, P2 responses to hits were more positive than P2 responses to correct rejections at all lags. (Note that correct rejections do not have a lag condition, but are overplotted at each to illustrate the repetition effect.)
