Perceptual learning increased P3 amplitude. (a) Grand average ERPs recorded at POz electrode for Session 1 (blue) and Session 2 (red). Vertical line at zero indicates the onset of TDT target array presentation, and the gray highlighted rectangle indicates the temporal window used for P3 analysis. P3 amplitude increased significantly following learning (mean P3 in Session 1: 3.89 μV, SD = 2.36; Session 2: 4.83 μV, SD = 2.53). (b) P3 topographical map 300 ms after stimulus onset for Session 1 (left), Session 2 (middle), and their difference (right).
