Figure 1.

A) Grand-average waveforms at a pooling of FC1, FC2, Cz, CP1, CP2 (where the LPP was scored), shown separately for participants with low and high meanness. Low/high meanness groups were created using the top and bottom terciles of meanness scores, for illustrative purposes only. B) Scalp distributions of amplitudes for unpleasant minus neutral pictures and pleasant minus neutral pictures from 2500-5000ms, shown separately for participants with low and high meanness. C) Partial regression plots depict the association between meanness and ΔLPP to unpleasant and pleasant pictures, respectively.
