Abstract: Hyperscanning methods are gaining prominence in psychophysiological research and yielding interesting insights into the neural mechanisms supporting interpersonal social engagement. However, the vast majority of that innovative work is being carried out in adolescents and adults. Given the known importance of dyadic social interactions for supporting early neurodevelopment, expanding hyperscanning methods to child studies presents a promising opportunity to broaden the field's understanding of the interplay between neural, behavioral, and environmental factors contributing to social connectedness. This scoping review summarizes the findings from the empirical, peer‐reviewed pediatric hyperscanning studies involving children 7 years of age or younger. We review methodological practices related to the experimental design of naturalistic social interaction paradigms and data analysis options for quantifying interpersonal neural synchrony, identify their strengths and knowledge gaps, and propose key areas for future study. Impact Statement: The increasing use of hyperscanning, where neural signals from multiple individuals engaged in shared activities are measured and analyzed simultaneously, expands the existing frameworks of social neuroscience. This scoping review of hyperscanning studies summarizes current methodological practices related to experimental design of naturalistic social interaction paradigms and data analysis approaches, and identifies key areas for future study with specific focus on early childhood, when dyadic interactions provide a critical foundation for neurodevelopmental outcomes.
