Abstract Much of a child’s early learning takes place during social interactions with others. Neural synchrony, the temporal alignment individuals’ functional brain activity, is neural mechanism that may support successful interaction, but its biological origins and sensitivity to environmental factors remain unknown. This study measures coherence between 4- 6-year-old children their mothers using wearable near-infrared spectroscopy (“fNIRS”) in collaborative problem-solving hyperscanning paradigm. Best practices fNIRS data processing are incorporated optimise quantification extricate environmental- task-related effects. Results suggest physiological noise extracerebral layer artificially inflated strength both oxygenated (“HbO2”) deoxygenated (“HbR”) haemoglobin. Coherence remained stronger than individual problem solving chromophores after reduction. Phase-scrambled pseudodyad analyses supported interpretation collaboration relates dynamics interaction rather task- or environmental-related components. Strength HbO2 was positively related task performance negatively background maternal stress. HbR also stress direction results were mixed. Overall, this provides new insight into nature play.

Group creation is the process by which group members collaborate to produce novel and useful ideas or products, including generation evaluation. However, interpersonal neural mechanism of during natural communication remains unclear. In this study, two groups same-sex dyads with similar individual creativity collaborated complete Product Improvement Task (creative condition) Item Purchase Plan (control condition), respectively. Functional near-infrared spectroscopy (fNIRS) was used record both members' activity in left prefrontal (lPFC) right temporal-parietal junction (rTPJ) regions task. Considering that role asymmetry may have an impact on patterns, we identified leaders followers based participant performance. The results showed creative condition had significantly lower synchronization (INS) superior temporal gyrus-left frontal gyrus, supramarginal middle gyrus than control condition. Partial multivariate Granger causality analyses revealed influence between bidirectional but stronger from other direction. addition, task, INS associated novelty, appropriateness, conflict views. All these findings suggest evaluation poor coupling due factors such as difficulty understanding ideas. performances be improved when can better integrate views reach collective understanding, intentions, goals. Furthermore, found there are differences dynamics different brain regions. related novelty decreased early stages, while appropriateness stages.

Interbrain substrates of role switching during mother–child interaction

Human Brain Mapping, Journal Year: 2024, Volume and Issue: 45(5)

Published: March 28, 2024

Abstract Mother–child interaction is highly dynamic and reciprocal. Switching roles in these back‐and‐forth interactions serves as a crucial feature of reciprocal behaviors while the underlying neural entrainment still not well‐studied. Here, we designed role‐controlled cooperative task with dual EEG recording to explore how differently two brains interact when mothers children hold different roles. When were actors observers, mother–child interbrain synchrony emerged primarily within theta oscillations frontal lobe, which correlated children's attachment their (self‐reported by mothers). reversed, this was shifted alpha central area associated mothers' perception relationship children. The results suggested an observer‐actor alignment actor's oscillations, related actor‐toward‐observer emotional bonding. Our findings contribute understanding established dynamically changed during interaction.

Non-verbal cues tone our communication. Previous studies found that non-verbal factors, such as spatial distance and gaze direction, significantly impact interpersonal However, little is known about the behind multi-brain neural correlates whether it could affect high-level creative group Here, we provided a new, scalable, neuro-based approach to explore effects of factors on different communication tasks, revealed underlying using fNIRS-based hyperscanning technique. Across two experiments, closer more direct angle promote collaborative behaviors, improve both non-creative outcomes, enhance inter-brain synchronization. Moreover, compared task, participants' network was intertwined when performing task. These findings suggest close serve positive social cues, bringing interacting brains into alignment optimizing information transfer, thus improving outcomes.

The so-called metaverse will allow users to blend real and virtual worlds in a seamless manner, thus drastically changing how humans interact, socialize, even work. While progress extended reality headsets, wireless communications, blockchain technologies quantum communications are paving the way for metaverse, many of emerging applications still focusing on only two human senses: hearing vision. In this position paper, we argue that order truly make immersive experiences, additional senses need be stimulated. Moreover, affective computing brain-computer interface principles incorporated interaction (be it human-human, human-avatar, avatar-avatar) more natural, sustainable solutions developed, so do not destroy our world while trying build version it. This future internet has been termed "the Internet Senses (IoS)". Here, highlight some challenges developing IoS, as well opportunities multisensory experiences bring manufacturing, retail, entertainment, healthcare domains.
