Decoding accuracy in Experiment 2. (A) 8-way classification accuracy of target position (chance = 0.125). The black line reflects significance at p < 10−3 (cluster based permutation test), shaded area is +/− s.e.m. Peak at 264 ms. Note again the similarity in temporal evolution with the N2pc (Fig. 3) and decoding accuracies of Experiment 1 (Fig. 4), although plausibly peaking slightly later because of the increase in the number of items on the screen. (B) Classsification accuracy per quadrant (chance = 0.5). (C) Separate N2pc components were computed for left versus right target objects at each of the four vertical elevations, indicated by color. Colored sections indicate p < 10−3 (cluster based permutation test).
