Why is the hyperscanning paradigm important for comparing the social brain across "digital" and "real-life" conditions? Introduction to special issue.

Abstract

The explosion of digital media has emerged quickly from the convergence of technological advances, pandemic urgency, and cultural changes that have now taken hold in the daily life of people around the world. With cell phone, tablet and laptop devices as well as broad internet service available to an estimated two-thirds of the world's population, the landscape of social interaction continues to change. "Social media" for personal, educational, business, health and other purposes is being used daily. With this shift, the field of social neuroscience has begun to consider both digital and in-person interactions. The hyperscanning technique lends itself well to this challenge and is beginning to be applied to study of varied social constructs as well as clinical samples. This special issue has assembled a set of papers specifically focused on hyperscanning as an informative approach to investigating digital vs. in-person interactions. Papers present conceptual, methodological, and primary data findings. Authors address issues of interpersonal stress regulation, shared and distinctive bodily and physiological characteristics of digital vs. in-person experiences, the effects of prior social interaction on emotional contagion, and the possible influence of BMI on neural synchrony during motor coordination.
