FIGURE 6.

The figure displays the grand averages at electrode site Pz as a function of dimensional repetition (left) and dimensional change (right) and S–R correspondence sequence (sequence types: c–C, n–C, c–N, n–N). Positive deflections are displayed downward. The gray area highlights the analyzed time-window of the P3b component (390–450 ms). Black lines signal current corresponding trials, gray lines signal current non-corresponding trials. Solid lines indicate previous corresponding and dashed lines indicate previous non-corresponding S–R relations. h = horizontal dimension, v = vertical dimension, c = corresponding, n = non-corresponding S–R relations. Small letters indicate previous trial features, capital letters current trial features of a trial sequence.
