Heatmap of facial expressivity as per AU intensity grouped by condition and valence type
Note∗. Boxplots with intensity ranges for each AU can be found in Figure S2. Greater average intensity of facial muscle activity is indicated in form of darker tones. Includes AUs used in model 2, except AU45, which could not be visualized in Py-Feat. To aid visualization, the most prominently used AUs are tagged in the small, encircled window on the right side of the plot.
