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

Figure 7 Heat map for correlations among variables in major depression group. Positive correlations are indicated in red, while negative correlations are marked in blue. ^aP < 0.05; ^bP < 0.01, ^cP < 0.001. MD: Major depression; HAMD: Hamilton Depression Scale; Early-LPP-E1: Late positive potentials early phase of experiment 1; Early-LPP-E3: Late positive potentials early phase of experiment 3; Med-LPP-E1: Late positive potentials medium phase of experiment 1; Med-LPP-E2: Late positive potentials medium phase of experiment 2; Med-LPP-E3: Late positive potentials medium phase of experiment 3; Late-LPP-E1: Late positive potentials late phase of experiment 1; Late-LPP-E3: Late positive potentials late phase of experiment 3; P1-E2: The P100 of experiment 2.
