Neural correlates of conditional reasoning dysfunction in major depression: An event-related potential study with the Wason selection task

Figure 3 Grand averaged P100 and topographical distribution of both healthy control and major depression groups. A: Grand averaged event-related potentials of experiment 2 in the healthy control (HC) group and major depression (MD) group; The time window corresponding to P100 is indicated by the gray shaded area; B: A topography map of the experiment 2 condition depicting the grand average amplitude of the difference wave within the 70-100 ms timeframe for the HC group and the MD group. HC: Healthy controls; MD: Major depression; E2: Precautionary Wason selection task.
