Giving and receiving touch are some of the most important social stimuli we exchange in daily life. By touching someone, we can communicate various types of information. Previous studies have also demonstrated that interpersonal touch may affect our altruistic behavior. A classic study showed that customers give bigger tips when they are lightly touched by a waitress, which has been called the Midas touch effect. Numerous studies reported similar effects of touch on different kinds of helping or prosocial behaviors. Here, we aim to examine the neural underpinnings of this effect by employing a functional magnetic resonance imaging approach. While lying in the scanner, participants played different rounds of the dictator game, a measure of prosocial behavior. Before each round, participants were touched (or not touched in the control condition) by an experimenter. We found that touching the hand increased the likeliness to behave prosocial (but not the general liking of control stimuli), thereby confirming the Midas touch effect. The effect was predicted by activity in the primary somatosensory cortex, indicating that the somatosensory cortex here plays a causal role in prosocial behavior. We conclude that the tactile modality in social life may be much more important than previously thought. [ABSTRACT FROM AUTHOR]

In recent years the study of dynamic, between-brain coupling mechanisms has taken social neuroscience by storm. In particular, interbrain synchrony (IBS) is a putative neural mechanism said to promote social interactions by enabling the functional integration of multiple brains. In this article, I argue that this research is beset with three pervasive and interrelated problems. First, the field lacks a widely accepted definition of IBS. Second, IBS wants for theories that can guide the design and interpretation of experiments. Third, a potpourri of tasks and empirical methods permits undue flexibility when testing the hypothesis. These factors synergistically undermine IBS as a theoretical construct. I finish by recommending measures that can address these issues. Interbrain synchrony is a putative neural mechanism said to promote social interactions by enabling the functional integration of multiple brains. Research on this topic has skyrocketed in recent years. However, the field lacks a widely accepted definition of interbrain synchrony. Interbrain synchrony wants for theories that can guide the design and interpretation of experiments. A plethora of empirical methods permit evidence consistent with the idea to accumulate without providing means to falsify it. These problems conspire to undermine the construct validity of the phenomenon. However, steps can be taken to address these issues. [ABSTRACT FROM AUTHOR]

This article focuses on the psychology of principled nonviolent activism, specifically ideas associated with Martin Luther King, Jr.'s philosophy of nonviolence and how they are compatible with attachment theory and related areas of modern neuroscience (e.g., attachment/social neuroscience and interpersonal neurobiology). The proposed Kingian Neuro-Relational Theory (KNRT) recognizes King as having a relational development approach to social justice. KNRT offers a way of understanding King's ideas to aid research and develop strategies for reducing many forms of societal violence, with eventual outcomes of improving mental and physical health via stress reduction, and subsequent creation of a more socially just world. KNRT is an integrative, multidisciplinary approach, incorporating the philosophy of nonviolence, attachment theory, social neuroscience, ecological systems theory, and personalistic philosophy. The theory highlights developmental and clinical implications of moving beyond tactical/pragmatic nonviolent activism (nonviolent direct action) to activism via embracing nonviolence as a principled way of life (nonviolent daily interactions). This theory is building on an earlier project that conveyed how King's philosophy of nonviolence is related to modern–day diversity and inclusion efforts. [ABSTRACT FROM AUTHOR]

Changes in socio-emotional functioning in people living with dementia (PLWD) are common; however, little is known about the broader effects these may have on wellbeing. This study examined socio-emotional functioning over time and associations with the wellbeing of PLWD and their family carers. One hundred and one individuals with a diagnosis of dementia and their respective carers completed the Social Emotional Questionnaire (assessing emotion recognition, empathy, social relationships and social behaviour) alongside measures of dementia severity, cognition, mood, stress, and relationship quality. Sixty-six dyads were reassessed on the same measures at 12 months post-baseline, and 51 dyads again at 20 months post-baseline. When rated by the PLWD, there was no change in socio-emotional functioning over time; however, carers reported a significant decline over time. For both carers and the PLWD, poorer wellbeing measures were indicative of worse socio-emotional functioning at Time 1, though only dementia type, quality of life and relationship quality impacted upon the trajectory of socio-emotional decline over time. Changes in social and emotional functioning are evident early in the course of dementia and worsen within 20 months. Both carer characteristics and those of the PWLD affected reporting of social and emotional functioning. These data are useful for guiding the provision of appropriate education and care.

Social cognitive processes, such as emotion perception and empathy, allow humans to navigate complex social landscapes and are associated with specific neural systems. In particular, theory of mind (ToM), which refers to our ability to decipher the mental states of others, is related to the dorsal medial prefrontal cortex and temporoparietal junction, which include portions of the default network. Both social cognition and the default network have been linked to the personality trait Agreeableness. We hypothesized that default network activity during a ToM task would positively predict social cognitive abilities and Agreeableness. In a 3T fMRI scanner, participants (N = 1050) completed a ToM task in which they observed triangles displaying random or social (i.e., human-like) movement. Participants also completed self-report measures of Agreeableness and tests of intelligence and social cognitive ability. In each participant, average blood oxygen level dependent responses were calculated for default network regions associated with social cognition, and structural equation modeling was used to test associations of personality and task performance with activation in those brain regions. Default network activation in the dorsal medial subsystem was greater for social versus random animations. Default network activation in response to social animations predicted better performance on social cognition tasks and, to a lesser degree, higher Agreeableness. Neural response to social stimuli in the default network may be associated with effective social processing and could have downstream effects on social interactions. We discuss theoretical and methodological implications of this work for social and personality neuroscience. [ABSTRACT FROM AUTHOR]

Mother-child brain-to-brain synchrony captures the temporal similarities in brain signals between dyadic partners, and has been shown to emerge during the display of joint behaviours. Despite the rise in the number of studies that investigate synchrony in naturalistic contexts, the use of varying methodological approaches to compute synchrony remains a central problem. When dyads engage in unstructured social interactions, the wide range of behavioural cues they display contribute to the use of varying lengths of signals to compute synchrony. The present functional Near-infrared Spectroscopy (fNIRS) study investigates how different methods to quantify brain signals during joint and non-joint portions of dyadic play affect the outcome of brain-to-brain synchrony. Three strategies to cope with unstructured data are tested and different signal lengths of 15, 20, 25, 30, 35, 40, 45s were used to determine the optimal method to sensitively capture synchrony. Results showed that using all available portions of the signals generated a greater number of less conservative results compared to the other two strategies, which were to compute the average synchrony for the joint and non-joint signals portions and to compute the difference between the average synchrony of joint and non-joint portions. From the different signal durations, only length portions of 25s to 35s generated significant results. These findings demonstrate that differences in computational approaches and signal lengths affect synchrony measurements and should be considered in naturalistic synchrony studies.

Introduction Interpersonally coordinated behaviors are crucial for social interactions.The “Theory of Mind,” or mentalization capacity, of an individual is essential for the establishment of behavioral synchronization. The Reading the Mind in the Eyes Test (RMET) is used to assess mentalization, social cognition and empathy. Previous RMET studies, investigated people in isolation, not in social situations. It is unclear how the RMET predicts functioning during real-life social interactions. Objectives To investigate the relationship between the performance measured on the RMET test and the synchronous behavior of two individuals interacting with each other during tasks requiring social collaboration. Methods Sample included healthy controls (HC,n=48) and patients with ADHD (n=26) or schizophrenia (SCH,n=36) from an ongoing EEG-hyperscanning study, employing a social coordination condition.We applied a Go/NoGo reaction time(RT) task performed by pairs of participants. Synchronous behavior was characterized by the correlation of participants’ RTs.We used the percent (%) correct responses from the RMET to characterize social cognition. Results In HC, with better social cognitive performance, the correlation of behavioral responses was significantly (p

Williams syndrome (WS) is a genetic condition characterized by an overly gregarious personality, including high empathetic concern for others. Although seemingly disparate from the profile of autism spectrum disorder (ASD), both are associated with deficits in social communication/cognition. Notably, the mirror neuron system (MNS) has been implicated in social dysfunction for ASD; yet, the integrity of this network and its association with social functioning in WS remains unknown. Magnetic resonance imaging (MRI) methods were used to examine the structural integrity of the MNS of adults with WS versus typically developing (TD) individuals. The Social Responsiveness Scale (SRS), a tool typically used to screen for social features of ASD, was also employed to assess the relationships between social functioning with the MNS morphology in WS participants. WS individuals showed reduced cortical surface area of MNS substrates yet relatively preserved cortical thickness as compared to TD adults. Increased cortical thickness of the inferior parietal lobule (IPL) was associated with increased deficits in social communication, social awareness, social cognition, and autistic mannerisms. However, social motivation was not related to anatomical features of the MNS. Our findings indicate that social deficits typical to both ASD and WS may be attributed to an aberrant MNS, whereas the unusual social drive marked in WS is subserved by substrates distinct from this network.

The new normal has made social distancing a new way of experiencing sociality. Social neuroscience has for a long time been concerned with studying the beneficial effects of social relationships, of physical contact. It is known that physical contact activates neurophysiological processes that reduce the perception of discomfort and even physical pain. So in the absence of physical contact, our social brain may be modulated differently when we are with others. But what could be the long-term effects of this normality? This mini-review focuses on highlighting with the support of social neuroscience evidence such as isolation, distancing can affect people's health. [ABSTRACT FROM AUTHOR]

Introduction: In recent years, with the popularity of many social media platforms worldwide, the role of "virtual social network platforms" in the field of cross-cultural communication has become increasingly important. Scholars in psychology and neuroscience, and cross-disciplines, are attracted to research on the motivation, mechanisms, and effects of communication on social media across cultures. Methods and Analysis: This paper collects the co-citation of keywords in "cultural psychology," "cross-culture communication," "neuroscience," and "social media" from the database of web of science and analyzes the hotspots of the literature in word cloud. Results: Based on our inclusion criteria, 85 relevant studies were extracted from a database of 842 papers. There were 44 articles on cultural communication on social media, of which 26 were from the perspective of psychology and five from the perspective of neuroscience. There are 27 articles that focus on the integration of psychology and neuroscience, but only a few are related to cross-cultural communication on social media. Conclusion: Scholars have mainly studied the reasons and implications of cultural communication on social media from the perspectives of cultural psychology and neuroscience separately. Keywords "culture" and "social media" generate more links in the hot map, and a large number of keywords of cultural psychology and neuroscience also gather in the hot map, which reflects the trend of integration in academic research. While cultural characteristics have changed with the development of new media and virtual communities, more research is needed to integrate the disciplines of culture, psychology, and neuroscience.

Social behavior varies across both individuals and species. Research to explain this variation falls under the purview of multiple disciplines, each with its own theoretical and empirical traditions. Integration of these disciplinary traditions is key to developing a holistic perspective. Here, we review research on the biology of social attachment, a phenomena in which individuals develop strong affective connections to one another. We provide a historical overview of research on social attachment from psychological, ethological and neurobiological perspectives. As a case study, we describe work on pair‐bonding in prairie voles, a socially monogamous rodent. This specific topic takes advantage of many biological perspectives and techniques to explain social bonds. Lastly, we conclude with an overview of multi‐dimensional conceptual frameworks that can be used to explain social phenomena, and we propose a new framework for research on individual variation in attachment behavior. These conceptual frameworks originate from philosophy, physics, ethology, cognitive science and neuroscience. The application and synthesis of such frameworks offers a rich opportunity to advance understanding of social behavior and its mechanisms. [ABSTRACT FROM AUTHOR]

How do we understand the experiences of characters in a movie? Similar to real life, viewers attribute mental states to characters through a process known as Theory of Mind (ToM). Filmmakers commonly use Dramatic Irony, a narrative device where the audience knows something that at least one characters does not. From a social neuroscience perspective, understanding the cognitive mechanisms that underlie dramatic irony can provide a remarkable opportunity to study ToM in a more ecologically relevant context. While descriptive narrative theories of dramatic irony exist, these have never been studied in relation to contemporary social neuroscience. In this opinion piece, we aim to bring together these two traditionally isolated disciplines to propose a cross-disciplinary research roadmap for investigating the social neuroscience of dramatic irony in cinema.

Labels serve as identifiers and convenient descriptors of inanimate and animate objects. In humans, given labels can easily become part of an individual's self-perceived identity. Negative labels ascribed to a person can result in internalized stigma , a state that will shape the subject's biography. This can ultimately impact the person's mental and physical health since perceived and/or anticipated stigma discourages the use of social and health services. Per definition, stigma involves labeling of persons with physical, mental, or social characteristics that do not match the observer's arbitrarily conditioned and calibrated sense of norms (public stigma); such labeling may eventually become embedded in rules, regulations, and laws (structural stigma). Internalized stigma projects onto a person's emotions and actions. Public (enacted) stigma results from stereotyping (collectively agreed-upon notions about a group of persons that are used to categorize these people) and devaluation, which subsequently leads to social distancing, discrimination, and blatant abuse of human rights. Much of what we know about stigma results from research in the psychosocial sciences and, more recently, from social neuroscience. The stigma around mental health has generated much attention in the field of psychiatry where, to date, most research has focussed on epidemiology and anti-stigma interventions. This essay intends to stimulate thought, debate, and research within the behavioral neuroscience community and, therefore, to inform evidence-based design and implementation of neuroscience-based approaches by other professionals working towards the elimination of the stigma attached to mental illness. The article starts by considering the concept of stigma and the psychological processes that give rise to the phenomenon; it also considers how projected and perceived stigma are multiplied. Finally, after a brief review of the few existing neuroscientific explorations of stigma, gaps in our knowledge of the neurobiological basis of stigma are identified and discussed.

Social cognition is a very important group of neurocognitive processes involved especially in social functioning; currently, the amount of research on this topic is increasing and suggests some considerations about its assessment, particularly in the child population. This article presents some of these considerations focussed on the theoretical models, the type of instrument and some suggestions for the assessment processes. Specifically, four considerations are proposed: to be clear about the purpose of the assessment, to identify the domains of social cognition and the instruments to assess them, to consider the approach to the assessment and to analyse the role of the cultural and social context, all these keeping in mind the children's benefit.

Despite the existence of unquestionable evidence of the success and benefits of neuroscience in explaining social phenomena through a new area of research known as social neuroscience, the social sciences show no particular interest in neuroscientific research into social phenomena. A possible solution for the conceptualization of the interdisciplinary connection of neuroscience and social sciences is the analogy with the existence of two perspectives in social psychology: sociological social psychology and psychological social psychology.

El objetivo de este artículo es proporcionar una aproximación teórica y didáctica a la interacción oral (IO) en las clases de conversación de Español como Lengua Extranjera (ELE) desde la perspectiva de la neurociencia social. Actualmente, debido al desarrollo tecnológico de la espectroscopia funcional del infrarrojo cercano mediante el hiperescáner es posible medir la actividad cerebral simultánea de varios estudiantes mientras realizan tareas de IO. Estos hallazgos pueden redimensionar nuestros conceptos pedagógicos en la clase de conversación. Por eso, venciendo las reticencias de los profesores de lenguas a los tecnicismos científicos, de manera rigurosa, y, a la vez, didáctica, esta investigación expone a los profesores de ELE las bases teóricas de la neurociencia social sobre la IO, y plantea sugerencias pedagógicas, que podrían ser incorporadas en las clases de conversación de ELE. ORAL INTERACTION AND SOCIAL NEUROSCIENCE IN THE SPANISH CONVERSATION CLASSES The objective of this paper is to provide a theoretical and didactic approach to oral interaction (OI) in Spanish as a Foreign Language (SFL) conversation classes from the perspective of social neuroscience. Currently, due to the technological development of functional near-infrared spectroscopy using hyperscanning it is possible to measure the simultaneous brain activity of several students while performing OI tasks. These findings can resize our pedagogical concepts in the conversation classes. Therefore, by overcoming the reluctance of language teachers to scientific technicalities, in a rigorous and, at the same time, didactic way, this research exposes to SFL teachers the theoretical foundations of social neuroscience about OI, and makes pedagogical suggestions, which could be incorporated into SFL conversation classes.

The new normal has made social distancing a new way of experiencing sociality. Social neuroscience has for a long time been concerned with studying the beneficial effects of social relationships, of physical contact. It is known that physical contact activates neurophysiological processes that reduce the perception of discomfort and even physical pain. So in the absence of physical contact, our social brain may be modulated differently when we are with others. But what could be the long-term effects of this normality? This mini-review focuses on highlighting with the support of social neuroscience evidence such as isolation, distancing can affect people’s health.

Motives motivate human behavior. Most behaviors are driven by more than one motive, yet it is unclear how different motives interact and how such motive combinations affect the neural computation of the behaviors they drive. To answer this question, we induced two prosocial motives simultaneously (multi-motive condition) and separately (single motive conditions). After the different motive inductions, participants performed the same choice task in which they allocated points in favor of the other person (prosocial choice) or in favor of themselves (egoistic choice). We used fMRI to assess prosocial choice-related brain responses and drift diffusion modeling to specify how motive combinations affect individual components of the choice process. Our results showed that the combination of the two motives in the multi-motive condition increased participants’ choice biases prior to the behavior itself. On the neural level, these changes in initial prosocial bias were associated with neural responses in the bilateral dorsal striatum. In contrast, the efficiency of the prosocial decision process was comparable between the multi-motive and the single-motive conditions. These findings provide insights into the computation of prosocial choices in complex motivational states, the motivational setting that drives most human behaviors.

Biobehavioral synchrony, the coordination of physiological and behavioral signals between mother and infant during social contact, tunes the child’s brain to the social world. Probing this mechanism from a two-brain perspective, we examine the associations between patterns of mother–infant inter-brain synchrony and the two well-studied maternal behavioral orientations—sensitivity and intrusiveness—which have repeatedly been shown to predict positive and negative socio-emotional outcomes, respectively. Using dual-electroencephalogram (EEG) recordings, we measure inter-brain connectivity between 60 mothers and their 5- to 12-month-old infants during face-to-face interaction. Thirty inter-brain connections show significantly higher correlations during the real mother–infant face-to-face interaction compared to surrogate data. Brain–behavior correlations indicate that higher maternal sensitivity linked with greater mother–infant neural synchrony, whereas higher maternal intrusiveness is associated with lower inter-brain coordination. Post hoc analysis reveals that the mother-right-frontal–infant-left-temporal connection is particularly sensitive to the mother’s sensitive style, while the mother-left-frontal–infant-right-temporal connection indexes the intrusive style. Our results support the perspective that inter-brain synchrony is a mechanism by which mature brains externally regulate immature brains to social living and suggest that one pathway by which sensitivity and intrusiveness exert their long-term effect may relate to the provision of coordinated inputs to the social brain during its sensitive period of maturation.

Mental perspectives can sometimes be changed by psychological interventions. For instance, when applied in the context of intergroup conflicts, interventions, such as the paradoxical thinking intervention, may unfreeze ingrained negative outgroup attitudes and thereby promote progress toward peacemaking. Yet, at present, the evaluation of interventions' impact relies almost exclusively on self-reported and behavioral measures that are informative, but are also prone to social desirability and self-presentational biases. In the present study, magnetoencephalography tracked neural alignment, before and after the paradoxical thinking intervention, during the processing of auditory narratives over the Israeli-Palestinian conflict and thereby evaluated the intervention's potential to change individuals' (n = 80) mental perspectives over the conflict. Compared to baseline, the conflict-targeted intervention yielded a specific significant increased neural alignment in the posterior superior temporal sulcus while processing incongruent as well as congruent political narratives of the conflict. This may be interpreted as a possible change in perspective over the conflict. The results and their interpretations are discussed in view of the critical added value of neuroimaging when assessing interventions to potentially reveal changes in mental perspectives or the way in which they are processed, even in contexts of entrenched resistance to reconsider one's ideological stance., (© The Author(s) 2024.

Political partisanship is often conceived as a lens through which people view politics. Behavioral research has distinguished two types of "partisan lenses"-policy-based and identity-based-that may influence peoples' perception of political events. Little is known, however, about the mechanisms through which partisan discourse appealing to policy beliefs or targeting partisan identities operate within individuals. We addressed this question by collecting neuroimaging data while participants watched videos of speakers expressing partisan views. A "partisan lens effect" was identified as the difference in neural synchrony between each participant's brain response and that of their partisan ingroup vs. outgroup. When processing policy-based messaging, a partisan lens effect was observed in socio-political reasoning and affective responding brain regions. When processing negative identity-based attacks, a partisan lens effect was observed in mentalizing and affective responding brain regions. These data suggest that the processing of political discourse that appeals to different forms of partisanship is supported by related but distinguishable neural-and therefore psychological-mechanisms, which may have implications for how we characterize partisanship and ameliorate its deleterious impacts., (© The Author(s) 2024.

Sharing emotional experiences impacts how we perceive and interact with the world, but the neural mechanisms that support this sharing are not well characterized. In this study, participants (N = 52) watched videos in an MRI scanner in the presence of an unfamiliar peer. Videos varied in valence and social context (i.e., participants believed their partner was viewing the same (joint condition) or a different (solo condition) video). Reported togetherness increased during positive videos regardless of social condition, indicating that positive contexts may lessen the experience of being alone. Two analysis approaches were used to examine both sustained neural activity averaged over time and dynamic synchrony throughout the videos. Both approaches revealed clusters in the medial prefrontal cortex that were more responsive to the joint condition. We observed a time‐averaged social‐emotion interaction in the ventromedial prefrontal cortex, although this region did not demonstrate synchrony effects. Alternatively, social‐emotion interactions in the amygdala and superior temporal sulcus showed greater neural synchrony in the joint compared to solo conditions during positive videos, but the opposite pattern for negative videos. These findings suggest that positive stimuli may be more salient when experienced together, suggesting a mechanism for forming social bonds. [ABSTRACT FROM AUTHOR]

Humans are an unusually prosocial species, who engage in social behaviors that include altruism—whereby an individual engages in costly or risky acts to improve the welfare of another person—care, and cooperation. Current perspectives on the neurobiology of human prosociality suggest that it is deeply rooted in the neuroendocrine architecture of the social brain and emphasize the modulatory role of the neuropeptide hormone oxytocin. In this review, we provide a conceptual overview of the neurobiology of prosocial behavior with a focus on oxytocin's modulatory role in human prosociality. Specifically, we aim to encourage a better understanding of the peptide's susceptibility to diverse factors that produce heterogeneity in outcomes and the resulting methodological implications for measuring the behavioral effects of oxytocin in humans. After providing an overview of the state-of-the-art research on oxytocin's exogenous use, we elaborate on the peptide's modulatory role in the context of care-based altruism, cooperation, and conflict and discuss its potential for therapeutic interventions in psychiatric disorders characterized by social dysfunction.

Advances in the understanding of developmental brain disorders such as autism spectrum disorders (ASDs) are being achieved through human neurogenetics such as, for example, identifying de novo mutations in SYNGAP1 as one relatively common cause of ASD. A recently developed rat line lacking the calcium/lipid binding (C2) and GTPase activation protein (GAP) domain may further help uncover the neurobiological basis of deficits in children with ASD. This study focused on social dominance in the tube test using Syngap+/Δ‐GAP (rats heterozygous for the C2/GAP domain deletion) as alterations in social behaviour are a key facet of the human phenotype. Male animals of this line living together formed a stable intra‐cage hierarchy, but they were submissive when living with wild‐type (WT) cage‐mates, thereby modelling the social withdrawal seen in ASD. The study includes a detailed analysis of specific behaviours expressed in social interactions by WT and mutant animals, including the observation that when the Syngap+/Δ‐GAP mutants that had been living together had separate dominance encounters with WT animals from other cages, the two higher ranking Syngap+/Δ‐GAP rats remained dominant whereas the two lower ranking mutants were still submissive. Although only observed in a small subset of animals, these findings support earlier observations with a rat model of Fragile X, indicating that their experience of winning or losing dominance encounters has a lasting influence on subsequent encounters with others. Our results highlight and model that even with single‐gene mutations, dominance phenotypes reflect an interaction between genotypic and environmental factors. [ABSTRACT FROM AUTHOR]

Many daily choices are based on one's own knowledge. However, when predicting other people's behavior, we need to consider the differences between our knowledge and other people's presumed knowledge. Social agents need a mechanism to use privileged information for their own behavior but exclude it from predictions of others. Using fMRI, we investigated the neural implementation of such social and personal predictions in healthy human volunteers of both sexes by manipulating privileged and shared information. The medial frontal cortex appeared to have an important role in flexibly making decisions using privileged information for oneself or predicting others' behavior. Specifically, we show that ventromedial PFC tracked the state of the world independent of the type of decision (personal, social), whereas dorsomedial regions adjusted their frame of reference to the use of privileged or shared information. Sampling privileged evidence not available to another person also relied on specific interactions between temporoparietal junction area and frontal pole. [ABSTRACT FROM AUTHOR]

Our current educational system is modeled after the mass production of industrial factories, characterized by individualism, standardization, and competition. The industrial model, while efficient, largely disregards that learning is an interpersonal process. Social connection and emotional attunement activate our neurobiology for learning, while anxiety, isolation and stress inhibit those same processes. This is because our brains evolved to learn in the context of kinship groups often called tribes. This paper offers scientific support for creating classroom cultures of social cohesion which optimize students’ social, emotional and cognitive development. We will also present practical applications for teachers that can be used to create tribal classroom environments within the parameters of a modern standardized curriculum.

Introduction: Alpha oscillations are unique in their capacity to relay neuronal information through a dual‐process named "gating by inhibition": rhythmic enhancement inhibits task‐irrelevant regions while rhythmic suppression engages task‐relevant regions in the brain. A social‐cognitive process that operates by relying on the suppression of the alpha rhythm in the primary somatosensory cortex (S1) is the ability to generate empathy. This phenomenon has been evidenced in dozens of electrophysiological studies targeting adult human subjects. Yet, recent studies on the neurodevelopment of empathy indicate that in younger age, empathy does not involve alpha suppression in S1 but only enhancement. More interestingly, right before adulthood, this rhythm is still enhanced, but in a remarkable shift, a pattern of suppression emerges. In this registered magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) study, we will capture frequency‐decomposed neural activity particularly at the alpha range and its corresponding hemodynamic response and target subjects at around 20 years old as a unique time‐window in development that allows investigating in parallel both low‐alpha suppression and high‐alpha enhancement. We aim to address two questions: (a) Does alpha power suppression in the S1 region during empathy correspond to BOLD increase in this region? (b) What is the functional role of alpha power enhancement during empathy development (BOLD signal increase or decrease)? Addressing these questions will particularly advance knowledge on the process of empathy in the brain, and the way in which it is underpinned by alpha oscillations. Moreover, examining these experimental outcomes can potentially lay the ground for future studies that would further examine the role of alpha oscillations in empathy during the course of development. Methods: Brain data of forty healthy individuals close to 20 years old will be recorded in two consecutive MEG and fMRI sessions while subjects observing physical pain versus neutral stimuli. Besides, each participant's subjective experiences wll be measred by questionnaires, interviews and rating of the stimuli. [ABSTRACT FROM AUTHOR]

Collaboration between two individuals is thought to be associated with the synchrony of two different brain activities. Indeed, prefrontal cortical activation and alpha frequency band modulation has been widely reported, but little is known about interbrain synchrony (IBS) changes occurring during social interaction such as collaboration or competition. In this study, we assess the dynamic of IBS variation in order to provide novel insights into the frequency band modulation underlying collaboration. To address this question, we used electroencephalography (EEG) to simultaneously record the brain activity of two individuals playing a computer‐based game facing four different conditions: collaboration, competition, single participation, and passive observation. The computer‐based game consisted of a fast button response task. Using data recorded in sensor space, we calculated an IBS value for each frequency band using both wavelet coherence transform and phase‐locking value and performed single‐subject analysis to compare each condition. We found significant IBS in frontal electrodes only present during collaboration associated with alpha frequency band modulation. In addition, we observed significant IBS in the theta frequency band for both collaboration and competition conditions, along with a significant single‐subject cortical activity. Competition is distinguishable through single‐subject activity in several regions and frequency bands of the brain. Performance is correlated with single‐subject frontal activation during collaboration in the alpha and beta frequency band. [ABSTRACT FROM AUTHOR]

Cognitive neuroscience seeks to discover the biological foundations of the human mind. One goal is to explain how mental operations are generated by the information processing architecture of the human brain. Our aim is to assess whether this is a well-defined objective. Our contention will be that it is not because the information processing of any given individual is not contained entirely within that individual's brain. Rather, it typically includes components situated in the heads of others, in addition to being distributed across parts of the individual's body and physical environment. Our focus here will be on cognition distributed across individuals, or on what we call the "community of knowledge," the challenge that poses for reduction of cognition to neurobiology and the contribution of cognitive neuroscience to the study of communal processes.

During the COVID-19 pandemic, we have seen that people can adapt quickly to ensure that their social needs are met after being forced to isolate and socially distance. Many individuals turned immediately to music, as evidenced by people singing from balconies, watching live concerts on social media, and group singing online. In this article, we show how these musical adaptations can be understood through the latest advances in the social neuroscience of music—an area that, to date, has been largely overlooked. By streamlining and synthesizing prior theory and research, we introduce a model of the brain that sheds light on the social functions and brain mechanisms that underlie the musical adaptations used for human connection. We highlight the role of oxytocin and the neurocircuitry associated with reward, stress, and the immune system. We show that the social brain networks implicated in music production (in contrast to music listening) overlap with the networks in the brain implicated in the social processes of human cognition—mentalization, empathy, and synchrony—all of which are components of herding; moreover, these components have evolved for social affiliation and connectedness. We conclude that the COVID-19 pandemic could be a starting point for an improved understanding of the relationship between music and the social brain, and we outline goals for future research in the social neuroscience of music. In a time when people across the globe have been unable to meet in person, they have found a way to meet in the music [ABSTRACT FROM AUTHOR]

Although empathy drives prosocial behaviors, it is not always a reliable source of information in moral decision making. In this essay, I integrate evolutionary theory, behavioral economics, psychology, and social neuroscience to demonstrate why and how empathy is unconsciously and rapidly modulated by various social signals and situational factors. This theoretical framework explains why decision making that relies solely on empathy is not ideal and can, at times, erode ethical values. This perspective has social and societal implications and can be used to reduce cognitive biases and guide moral decisions. [ABSTRACT FROM AUTHOR]

Abstract Collaboration between two individuals is thought to be associated with the synchrony of two different brain activities. Indeed, prefrontal cortical activation and alpha frequency band modulation has been widely reported, but little is known about interbrain synchrony (IBS) changes occurring during social interaction such as collaboration or competition. In this study, we assess the dynamic of IBS variation in order to provide novel insights into the frequency band modulation underlying collaboration. To address this question, we used electroencephalography (EEG) to simultaneously record the brain activity of two individuals playing a computer‐based game facing four different conditions: collaboration, competition, single participation, and passive observation. The computer‐based game consisted of a fast button response task. Using data recorded in sensor space, we calculated an IBS value for each frequency band using both wavelet coherence transform and phase‐locking value and performed single‐subject analysis to compare each condition. We found significant IBS in frontal electrodes only present during collaboration associated with alpha frequency band modulation. In addition, we observed significant IBS in the theta frequency band for both collaboration and competition conditions, along with a significant single‐subject cortical activity. Competition is distinguishable through single‐subject activity in several regions and frequency bands of the brain. Performance is correlated with single‐subject frontal activation during collaboration in the alpha and beta frequency band.

Abstract Introduction Alpha oscillations are unique in their capacity to relay neuronal information through a dual‐process named “gating by inhibition”: rhythmic enhancement inhibits task‐irrelevant regions while rhythmic suppression engages task‐relevant regions in the brain. A social‐cognitive process that operates by relying on the suppression of the alpha rhythm in the primary somatosensory cortex (S1) is the ability to generate empathy. This phenomenon has been evidenced in dozens of electrophysiological studies targeting adult human subjects. Yet, recent studies on the neurodevelopment of empathy indicate that in younger age, empathy does not involve alpha suppression in S1 but only enhancement. More interestingly, right before adulthood, this rhythm is still enhanced, but in a remarkable shift, a pattern of suppression emerges. In this registered magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) study, we will capture frequency‐decomposed neural activity particularly at the alpha range and its corresponding hemodynamic response and target subjects at around 20 years old as a unique time‐window in development that allows investigating in parallel both low‐alpha suppression and high‐alpha enhancement. We aim to address two questions: (a) Does alpha power suppression in the S1 region during empathy correspond to BOLD increase in this region? (b) What is the functional role of alpha power enhancement during empathy development (BOLD signal increase or decrease)? Addressing these questions will particularly advance knowledge on the process of empathy in the brain, and the way in which it is underpinned by alpha oscillations. Moreover, examining these experimental outcomes can potentially lay the ground for future studies that would further examine the role of alpha oscillations in empathy during the course of development. Methods Brain data of forty healthy individuals close to 20 years old will be recorded in two consecutive MEG and fMRI sessions while subjects observing physical pain versus neutral stimuli. Besides, each participant's subjective experiences wll be measred by questionnaires, interviews and rating of the stimuli.

Economic objectification is a form of dehumanization in which workers are treated as tools for enhancing productivity. It can lead to self-objectification in the workplace, which is when people perceive themselves as instruments for work. This can cause burnout, emotional drain, and a modification of self-perception that involves a loss of human attributes such as emotions and reasoning while focusing on others’ perspectives for evaluating the self. Research on workers self-objectification has mainly analyzed the consequences of this process without exploring the brain activity that underlies the individual’s experiences of self-objectification. Thus, this project explores the electroencephalographic (EEG) changes that occur in participants during an economic objectifying task that resembled a job in an online store. After the task, a self-objectification questionnaire was applied and its resulting index was used to label the participants as self-objectified or non-self-objectified. The changes over time in EEG event-related synchronization (ERS) and partial directed coherence (PDC) were calculated and compared between the self-objectification groups. The results show that the main differences between the groups in ERS and PDC occurred in the beta and gamma frequencies, but only the PDC results correlated with the self-objectification group. These results provide information for further understanding workers’ self-objectification. These EEG changes could indicate that economic self-objectification is associated with changes in vigilance, boredom, and mind-wandering.

Robots start to play a role in our social landscape, and they are progressively becoming responsive, both physically and socially. It begs the question of how humans react to and interact with robots in a coordinated manner and what the neural underpinnings of such behavior are. This exploratory study aims to understand the differences in human-human and human-robot interactions at a behavioral level and from a neurophysiological perspective. For this purpose, we adapted a collaborative dynamical paradigm from the literature. We asked 12 participants to hold two corners of a tablet while collaboratively guiding a ball around a circular track either with another participant or a robot. In irregular intervals, the ball was perturbed outward creating an artificial error in the behavior, which required corrective measures to return to the circular track again. Concurrently, we recorded electroencephalography (EEG). In the behavioral data, we found an increased velocity and positional error of the ball from the track in the human-human condition vs. human-robot condition. For the EEG data, we computed event-related potentials. We found a significant difference between human and robot partners driven by significant clusters at fronto-central electrodes. The amplitudes were stronger with a robot partner, suggesting a different neural processing. All in all, our exploratory study suggests that coordinating with robots affects action monitoring related processing. In the investigated paradigm, human participants treat errors during human-robot interaction differently from those made during interactions with other humans. These results can improve communication between humans and robot with the use of neural activity in real-time.
