Presence of spouse enhances brain-to-brain synchrony

Link – Physical presence of spouse enhances brain-to-brain synchrony in co-parenting couples. Abstract Co-parenting spouses who live together remain in close physical proximity to each other and regularly engage in reciprocal social interactions in joint endeavors to coordinate their caregiving. Although bi-parental rearing is a common occurrence in humans, the influence of the physical presence […]

Gender affects the interaction during group creative idea generation.

Link – Gender of partner affects the interaction pattern during group creative idea generation. Abstract This study aimed to determine how gender composition affects the group creative process. Participants were recruited into dyads with different gender compositions (female-male dyad, F-M; female-female, F-F; male-male, and M-M) to solve two problems. One problem demanded creativity alternative use […]

The “gift effect” on functional brain connectivity

Link – The “gift effect” on functional brain connectivity. Inter-brain synchronization when prosocial behavior is in action. Abstract The gift exchange represents a moment that characterizes interpersonal interactions. In particular, research in psychological and neuroscientific fields aimed to observe the social function of gift exchange. Specifically, the present study aimed to investigate the effects of […]

Optimization of wavelet coherence analysis in fNIRS

Link – Optimization of wavelet coherence analysis as a measure of neural synchrony during hyperscanning using functional near-infrared spectroscopy. Abstract Significance: The expanding field of human social interaction is enabled by functional near-infrared spectroscopy (fNIRS) that acquires hemodynamic signals during live two-person interactions. These advances call for development of methods to quantify interactive processes. Aim: […]

Hyperscanning: Neural Inter-brain Underpinnings of Social Interaction


Link – Hyperscanning: A Valid Method to Study Neural Inter-brain Underpinnings of Social Interaction. Abstract Social interactions are a crucial part of human life. Understanding the neural underpinnings of social interactions is a challenging task that the hyperscanning method has been trying to tackle over the last two decades. Here, we review the existing literature […]

Real-Time Eye-to-Eye Contact fNIRS

Link – Real-Time Eye-to-Eye Contact Is Associated With Cross-Brain Neural Coupling in Angular Gyrus. Abstract Direct eye contact between two individuals is a salient social behavior known to initiate and promote interpersonal interaction. However, the neural processes that underlie these live interactive behaviors and eye-to-eye contact are not well understood. The Dynamic Neural Coupling Hypothesis […]

The Neural Correlates of Group Coordination

Link – The neural correlates of reaching focal points. Abstract In pure-coordination games where there are multiple Nash equilibria, the selection of coordinated responses is inexplicable by rational-choice theory – yet coordination is ubiquitous in daily interactions. The psychological game theory therefore evokes the idea of focal-points: some equilibria being chosen due to its salience, […]

fNIRS Hyperscanning Synchronization

Link – Self-other overlap and interpersonal neural synchronization serially mediate the effect of behavioral synchronization on prosociality. Soc Cogn Affect Neurosci. 2020 Feb 12;: Authors: Feng X, Sun B, Chen C, Li W, Wang Y, Zhang W, Xiao W, Shao Y Abstract Behavioral synchronization has been found to facilitate social bonding and prosociality but the […]

Instructor-learner brain coupling with fNIRS

Link – Instructor-learner brain coupling discriminates between instructional approaches and predicts learning. Abstract The neural mechanisms that support naturalistic learning via effective pedagogical approaches remain elusive. Here we used functional near-infrared spectroscopy to measure brain activity from instructor-learner dyads simultaneously during dynamic conceptual learning. Results revealed that brain-to-brain coupling was correlated with learning outcomes, and, […]

Bonding between teachers and students

Link – Affiliative bonding between teachers and students through interpersonal synchronization in brain activity. Soc Cogn Affect Neurosci. 2020 Feb 05;: Authors: Zheng L, Liu W, Long Y, Zhai Y, Zhao H, Bai X, Zhou S, Li K, Zhang H, Liu L, Guo T, Ding G, Lu C Abstract Human beings organize socially. Theories have […]
