Development of a Synchronization Coefficient for Biosocial Interactions in Groups and Teams

---

Body movements, autonomic arousal, and electroencephalograms (EEGs) of group members
are often coordinated or synchronized with those of other group members. Linear and
nonlinear measures of synchronization have been developed for pairs of individuals, but
little work has been done on measures of synchronization for groups. We define a new
synchronization coefficient, SE, for a group based on pairwise correlations in time series
data and employing the notions of a group driver, who most drives the group’s responses,
and empath, who is most driven by the group. SE is developed here in the context of
emotional synchronization based on galvanic skin response time series. A simulation study
explores its properties, the balance between strong versus weak autocorrelational effects,
transfer, group size, and direct versus oscillatory functions. Distributions of SE are not
affected by group size up to 16 members. Norms for interpreting the coefficient are
presented along with directions for new research.
