Illustration of the emotional modulation of the late positive potential (LPP) cluster: Angry pictures lead to an enhanced LPP compared to neutral pictures. (a): Topography of t-values averaged across the significant time points. The size of the marked sensors is displayed proportional to their contribution to the cluster. (b): Topography of the scalp potential difference. The size of the marked sensors is displayed proportional to their contribution to the cluster. (c): Box plot and single subject values from the cluster. Blue lines indicate a more positive LPP for angry compared to neutral pictures, red the opposite. Asterisks illustrate the significance of exploratory post-hoc subgroup comparisons: *** p < 0.001, * p < 0.05, ns p > 0.05. (d): Time course of the respective LPP cluster. Colored shaded areas signify standard errors. Grey shaded areas signify the latency of the cluster.
