Fig. 2: Example trajectories for a stranger dyad (left) and a friend dyad (right) along the valence dimension.
From: Hyperscanning shows friends explore and strangers converge in conversation
Only one dimension is plotted to facilitate interpretation. Over the course of a trial, this stranger dyad converged along the valence dimension, whereas the friend dyad diverged. The trajectories and distance lines have been smoothed to facilitate interpretation. For smoothing, a loess regression was used with a 20% smoothing span for individual valence locations and a 70% smoothing span for distance between partners.
