Detection of Nonverbal Synchronization through Phase Difference in Human Communication
Fig 5
Total results from the remote communication condition.
Distribution of the mean relative frequency of synchronized head nods across all pairs in the remote communication condition. A smoothing spline curve (red line) is fitted to the mean relative frequency of synchronized head nods across all pairs and the vertical gray line shows the mean phase difference in remote communication. The horizontal axis represents the phase difference when head nod synchronization occurs, and the vertical axis indicates the frequency of head nod synchronization. Negative values on the horizontal axis indicate that the student’s head nod precedes that of the teacher, whereas positive values indicate the reverse.
