On the same wavelength—Do parents and children understand each other better if their brains are “in sync”?

Humans are social beings by nature. We often (unconsciously) imitate each other’s behaviors—think of yawning or laughing. Recent research shows that this imitation extends even beyond actions; it happens in our brains, too. State-of-the-art neuroimaging techniques reveal that interpersonal neural synchrony, where the brain activities of two or more interacting people align, is important for understanding others, starting from early childhood. In our article, we explore how interpersonal neural synchrony occurs during parent-child interactions and how it relates to behavior, relationship quality, and gender.

Dr Pascal Vrticka is a social neuroscientist with strong ties to developmental & social psychology. His research focuses on the psychological, behavioural, biological, and brain basis of human social interaction, attachment and caregiving. Besides measuring neurobiological responses to different kinds of social versus non-social information in single participants using (functional) magnetic resonance imaging ([f]MRI) and electroencephalography (EEG), Dr Vrticka most recently started to assess bio-behavioural synchrony in interacting pairs using functional near-infrared spectroscopy (fNIRS) hyperscanning. The main question thereby is how romantic partners and parents with their children get “in sync” when they solve problems together or talk to each other. Dr Vrticka furthermore relates the obtained individual and dyadic behavioural, biological, and brain measures to interindividual differences in relationship quality – particularly attachment and caregiving. In doing so, he refers to attachment theory that provides a suitable theoretical framework on how we initiate and maintain interpersonal relationships across the life span. With his research, Dr Vrticka is promoting a new area of investigation: the social neuroscience of human attachment.
