Fig 3. The effect of co-presence on autonomic ISC.

Fig 3

A. Control (H0) distributions (not co-present) and the experimental means (co-present, dashed lines), for both autonomic measures (ISCEDA, ISCHR) and for both emotional movies. H0 distributions represent movie-driven ISC of ANS signals. As can be seen in the figure, the experimental group-wise ISCs fall in the right tail of the control distributions, indicating the positive effect of co-presence on synchronization of participants’ autonomic activity. B. Time shifts in ANS synchronization: we assessed whether the ANS signals of co-present individuals were more tightly linked in time. Figure presents the control (H0) distributions and the experimental means (dashed lines) of the time lags in which two ANS signals exhibited maximal ISC. As can be seen in the figure, the time shifts in ANS synchronization of the co-present participants were significantly smaller in three out of four ANS measures. Lag_EDA in the positive movie showed a trend towards significance.
