Multimodal hyperscanning reveals that synchrony of body and mind are distinct in mother-child dyads

NeuroImage, Journal Year: 2022, Volume and Issue: 251, P. 118982 - 118982

Published: Feb. 8, 2022

Hyperscanning studies have begun to unravel the brain mechanisms underlying social interaction, indicating a functional role for interpersonal neural synchronization (INS), yet that drive INS are poorly understood. The current study, thus, addresses whether is functionally-distinct from synchrony in other systems - specifically autonomic nervous system and motor behavior. To test this, we used concurrent near-infrared spectroscopy electrocardiography recordings, while N = 34 mother-child stranger-child dyads engaged cooperative competitive tasks. Only domain was higher compared observed. Further, were positively related during competition but not cooperation. These results suggest different behavioral biological may reflect distinct processes. Furthermore, they show increased unlikely be explained solely by shared arousal similarities, supporting recent theories postulate close relationships.

Osteopathic Care as (En)active Inference: A Theoretical Framework for Developing an Integrative Hypothesis in Osteopathy

Frontiers in Psychology, Journal Year: 2022, Volume and Issue: 13

Osteopathy is a person-centred healthcare discipline that emphasizes the body’s structure-function interrelationship—and its self-regulatory mechanisms—to inform whole-person approach to health and wellbeing. This paper aims provide theoretical framework for developing an integrative hypothesis in osteopathy, which based on enactivist active inference accounts. We propose osteopathic care can be reconceptualised under (En)active as unifying framework.

Spontaneous dyadic behavior predicts the emergence of interpersonal neural synchrony

NeuroImage, Journal Year: 2023, Volume and Issue: 277, P. 120233 - 120233

Published: June 21, 2023

Synchronization of neural activity across brains – interpersonal synchrony (INS) is emerging as a powerful marker social interaction that predicts success multi-person coordination, communication, and cooperation. As the origins INS are poorly understood, we tested whether how might emerge from spontaneous dyadic behavior. We recorded (EEG) human behavior (full-body kinematics, eye movements facial expressions) while dyads participants were instructed to look at each other without speaking or making co-verbal gestures. made four fundamental observations. First, despite absence structured task, emerged spontaneously only when able see other. Second, show such INS, comprising specific spectral topographic profiles, did not merely reflect intra-personal modulations activity, but it rather reflected real-time dyad-specific coupling activities.

Your turn, my turn. Neural synchrony in mother–infant proto-conversation

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 378(1875)

Published: March 6, 2023

Even before infants utter their first words, they engage in highly coordinated vocal exchanges with caregivers. During these so-called proto-conversations, caregiver–infant dyads use a presumably universal communication structure—turn-taking, which has been linked to favourable developmental outcomes. However, little is known about potential mechanisms involved early turn-taking. Previous research pointed interpersonal synchronization of brain activity between adults and preschool-aged children during Here, we assessed caregivers at 4–6 months age ( N = 55) face-to-face interaction. We used functional-near infrared spectroscopy hyperscanning measure dyads' microcoded also measured infants’ inter-hemispheric connectivity as an index for maturity later vocabulary size attachment security outcomes potentially The results showed that more frequent turn-taking was related neural synchrony, but the strength relation decreased over course proto-conversation. Importantly, positively associated infant size, not security. Taken together, findings shed light on facilitating preverbal stress importance emerging child language development.

Interpersonal synchronization of spontaneously generated body movements

iScience, Journal Year: 2023, Volume and Issue: 26(3), P. 106104 - 106104

Published: Feb. 1, 2023

Interpersonal movement synchrony (IMS) is central to social behavior in several species. In humans, IMS typically studied using structured tasks requiring participants produce specific body movements. Instead, spontaneously generated (i.e., not instructed) movements have received less attention. To test whether spontaneous synchronize interpersonally, we recorded full-body kinematics from dyads of who were only asked sit face-to-face and look at each other. We manipulated interpersonal (i) visual contact (ii) spatial proximity. found that synchronized across when they could see other regardless This synchronization emerged very rapidly did selectively entail homologous parts (as mimicry); rather, the generalized nearly all possible combinations parts. Hence, alone can lead IMS. More generally, our results highlight be under natural unconstrained conditions.

A growing body of research shows that the universal capacity for music perception and production emerges early in development. Possibly building on this predisposition, caregivers around world often communicate with infants using songs or speech entailing song-like characteristics. This suggests might be one earliest developing most accessible forms interpersonal communication, providing a platform studying communicative behavior. However, little has examined truly contexts. The current work aims to facilitate development experimental approaches rely dynamic naturalistic social interactions. We first review two longstanding lines examine musical interactions by focusing either caregiver infant.
