Correlations between Individual Features of Electrodermal Response During Viewing of the Same Videos

In the past few years, much attention has been given to the development of neurophysiological methods of analyzing social interactions between subjects in response to natural stimuli presented in videos. This article describes a methodological approach for assessing similarities, and differences in how videos are perceived by different subjects based on their phasic electrodermal response (EDR). Experiments with viewing of videos revealed statistically significant correlations of electrodermal reactions in different subjects that made it possible to distinguish groups with similar or differing types of perception of the films. The results obtained demonstrate to our mind the possibility of using EDR as a simple method for quantifying autonomous nervous activity to assess the emotional, and activation components of interpersonal interaction.
