Figure 5
(A) Time-voltage plots and scalp-topographies showing the CPP in the blocks prior to the switch in cue-condition contingencies. Inserts show single-subject data for CPP amplitude and slope across conditions. Scalp topographies show voltage averages 180 to 80 ms prior to response. All topographies are thresholded between 2 and 7 µV. Data are not smoothed for display purposes. Shaded error bars depict the standard error of the mean. (B) CPP amplitude and slope plotted on the single-subject level for fast and slow trials separately. Single dots show single-subject data, bars display mean of the distribution (solid line), 95% confidence interval (dark grey shaded area), and 1 standard deviation (light grey shaded area). Amplitude differences across conditions show little variation by RT, however, RT does modulate differences in slope across conditions. Time-window for Amplitude: 180 to 80 ms prior to response. Time-window for calculation of Slope: 400 to 100 ms prior to response.
