Heterogeneity of raw facial expression correspondence (correlations) among dyads. (a) Some dyads showed high correspondence of only positive affect, (b) some showed no correspondence of either positive or negative affect, (c) some showed high correspondence of both positive and negative affect, and (d) some showed positive correspondence of positive affect but negative correspondence of negative affect. Intensity ratings range from 1 (no emotion) to 7 (extreme emotion) within each 10-s interval across the 10-min discussion.
