Figure 6
Time-voltage plots and scalp-topographies showing the CPP in the last block prior to the switch in cue-condition contingencies (left), and in the switch block (right). Inserts show single-subject data for CPP amplitude and slope across conditions. 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). Both measures reflect conditions, and amplitude shows more modulation by the switch. Scalp topographies show voltage averages across 40 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. Time-window for Amplitude: 180 to 80 ms prior to response. Time-window for calculation of Slope: 400 to 100 ms prior to response.
