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

Figure 4 Grand averaged late positive potential (early phase) and topographical distribution of both healthy control and major depression groups. A-D: Grand averaged event-related potentials of different experiments in the healthy control (HC) and major depression (MD) group; the time window corresponding to late positive potential (LPP) early phase is indicated by the gray shaded area; E-H: A topography map of different experiments depicting the mean amplitude of LPP early phase within the 350-550 ms time window for the HC and MD group. HC: Healthy controls; MD: Major depression; E1: Social contract Wason selection task; E2: Precautionary Wason selection task; E3: Descriptive Wason selection task; E4: Abstract Wason selection task.
