Neural correlates of impairments in music emotion processing in major depressive disorder: Evidenced from an event-related potential study

Figure 8 This correlation matrix heatmap illustrates relationships among reaction times, accuracy in neutral/negative/positive emotional tasks, and Hamilton Depression Rating Scale scores in major depressive disorder patients. Color intensity and dot size reflect correlation strength (dark blue = strong negative, light = positive). Positive correlations exist within reaction times and within accuracy across emotions; Hamilton Depression Rating Scale shows negative correlations with several emotional processing indicators, quantifying links between emotional cognition and depressive severity in major depressive disorder. RTs: Reaction times; ACC: Accuracy; HAMD: Hamilton Depression Rating Scale.
