As individuals increasingly engage in social interactions through digital mediums, understanding the neuroscientific underpinnings of such exchanges becomes a critical challenge and a valuable opportunity. In line with a second-person neuroscience approach, understanding the forms of interpersonal syntonisation that occur during digital interactions is pivotal for grasping the mechanisms underlying successful collaboration in virtual spaces. The hyperscanning paradigm, involving the simultaneous monitoring of the brains and bodies of multiple interacting individuals, seems to be a powerful tool for unravelling the neural correlates of interpersonal syntonisation in social exchanges. We posit that such approach can now open new windows on interacting brains' responses even to digitally-conveyed social cues, offering insights into how social information is processed in the absence of traditional face-to-face settings. Yet, such paradigm shift raises challenging methodological questions, which should be answered properly to conduct significant and informative hyperscanning investigations. Here, we provide an introduction to core methodological issues dedicated to novices approaching the design of hyperscanning investigations of remote exchanges in natural settings, focusing on the selection of neuroscientific devices, synchronization of data streams, and data analysis approaches. Finally, a methodological checklist for devising robust hyperscanning studies on digital interactions is presented.

Aggression can be categorized into reactive aggression (RA) and proactive aggression (PA) based on their underlying motivations. However, previous research has rarely identified the relationship between femininity and RA/PA, and there is a lack of understanding regarding the femininity-related neurofunctional basis of these aggressive behaviors. Thus, this study first examined the relationships between femininity and aggression, then explored the aggression-by-femininity interactions on the fractional amplitude of low-frequency fluctuations using resting-state fMRI among 705 university participants (mean age = 19.14 ± 0.99). The behavioral data indicated that femininity was more negatively associated with RA and PA when masculinity was controlled for. Additionally, the neural data revealed that femininity-specific relationships of RA in the left middle occipital gyrus (i.e. individuals with low femininity had positive relationships between RA and the left middle occipital gyrus, whereas those with high femininity had negative relationships) as well as of PA in the left middle frontal gyrus (i.e. individuals with high femininity showed significant negative relationships, whereas those with low femininity did not exhibit significant relationships). These findings reflect that individuals with varying levels of femininity exhibit distinct neural bases when expressing different subtypes of aggression, which are associated with societal expectations of gender.

The neurobiology of typical moral cognition involves the interaction of frontal, limbic, and temporoparietal networks. There is still much to be understood mechanistically about how moral processing is disrupted; such understanding is key to combating antisociality. Neuroscientific models suggest a key role for attention mechanisms in atypical moral processing. We hypothesized that attention-bias toward alcohol cues in alcohol use disorder (AUD) leads to a failure to properly engage with morally relevant stimuli, reducing moral processing. We recruited patients with AUD ( = 30) and controls ( = 30). During functional magnetic resonance imaging, participants viewed pairs of images consisting of a moral or neutral cue and an alcohol or neutral distractor. When viewing moral cues paired with alcohol distractors, individuals with AUD had lower medial prefrontal cortex engagement; this pattern was also seen for left amygdala in younger iAUDs. Across groups, individuals had less engagement of middle/superior temporal gyri. These findings provide initial support for AUD-related attention bias interference in sociomoral processing. If supported in future longitudinal and causal study designs, this finding carries potential societal and clinical benefits by suggesting a novel, leverageable mechanism and in providing a cognitive explanation that may help combat persistent stigma.

Autism Spectrum Disorder (ASD) is defined by distinctive socio-cognitive behaviors that deviate from typical patterns. Notably, social imitation skills appear to be particularly impacted, manifesting early on in development. This paper compared the behavior and inter-brain dynamics of dyads made up of two typically developing (TD) participants with mixed dyads made up of ASD and TD participants during social imitation tasks. By combining kinematics and EEG-hyperscanning, we show that individuals with ASD exhibited a preference for the follower rather than the lead role in imitating scenarios. Moreover, the study revealed inter-brain synchrony differences, with low-alpha inter-brain synchrony differentiating control and mixed dyads. The study's findings suggest the importance of studying interpersonal phenomena in dynamic and ecological settings and using hyperscanning methods to capture inter-brain dynamics during actual social interactions.

How obeying orders impacts moral decision-making remains an open question, despite its significant societal implications. The goal of this study was to determine if cognitive conflict, indexed by mid-frontal theta activity observed before an action, is influenced by the context of obedience. Participants came in pairs and were assigned roles as either agent or victim. Those in the agent role could either decide freely or follow the experimenter's instructions to administer (or refrain from administering) a mildly painful electric shock to the victim in exchange for a small monetary reward. Mid-frontal theta activity was recorded before the agent made their keypress. Results indicated that mid-frontal theta activity was reduced when participants obeyed the experimenter's orders compared to when they acted of their own volition, even though the outcomes of the actions were similar. This finding suggests that obeying orders diminishes cognitive conflict preceding moral decisions that could harm another person. This study sheds light on a potential mechanism explaining how obedience can blurr morality and lessen our natural aversion to harming others.

Theory of Mind (ToM) is understanding others' minds. Empathy is an insight into emotions and feelings of others. Persons with multiple sclerosis (pwMS) may experience impairment in ToM and empathy. To investigate ToM, empathy, and their relationship with neuroimaging, neuropsychological, and neuropsychiatric data. 41 pwMS and 41 HC were assessed using RMET for ToM, EQ, BICAMS, HADS. Cortical and subcortical gray matter volumes were calculated with Freesurfer from 3T MRI scans. pwMS showed lower EQ scores (44.82 ± 11.9 vs 51.29 ± 9.18, = 0.02) and worse RMET performance (22.37 ± 4.09 vs 24,47 ± 2.93, = 0.011). Anxiety and depression were higher in pwMS. EQ correlated with subcortical (amygdala) and cortical (anterior cingulate) volumes. RMET correlated with cortical volumes (posterior cingulate, lingual). In regression analysis, amygdala volume was the single predictor of empathy performance ( = 0.041). There were no significant correlations between social cognitive tests and general cognition. A weak negative correlation was found between EQ and the level of anxiety ( = -0.342, = 0.038) The present study indicates that pwMS have impairment on ToM and empathy. The performance of ToM and empathy in MS is linked to the volumes of critical brain areas involved in social cognition.

Healthcare professionals play a vital role in conveying sensitive information as patients undergo stressful, demanding situations. However, the underlying neurocognitive dynamics in routine clinical tasks remain underexplored, creating gaps in healthcare research and social cognition models. Here, we examined whether the type of clinical task may differentially affect the emotional processing of nursing students in response to the emotional reactions of patients. In a within-subjects design, 40 nursing students read clinical cases prompting them to make procedural decisions or to respond to a patient with a proper communicative decision. Afterward, participants read sentences about patients' emotional states; some semantically consistent and others inconsistent along with filler sentences. EEG recordings toward critical words (emotional stimuli) were used to capture ERP indices of emotional salience (EPN), attentional engagement (LPP) and semantic integration (N400). Results showed that the procedural decision task elicited larger EPN amplitudes, reflecting pre-attentive categorization of emotional stimuli. The communicative decision task elicited larger LPP components associated with later elaborative processing. Additionally, the classical N400 effect elicited by semantically inconsistent sentences was found. The psychophysiological measures were tied by self-report measures indexing the difficulty of the task. These results suggest that the requirements of clinical tasks modulate emotional-related EEG responses.

Uncertainty is unavoidable, and maladaptive responses to uncertainty may underlie the etiology and maintenance of psychopathology. A general tendency to associate uncertainty with aversive consequences, a type of covariation bias, can amplify aversive emotional experiences. To address questions about uncertainty during emotion regulation, we examined the Late Positive Potential (LPP) - an electrocortical marker of attention to and appraisal of motivationally relevant emotional stimuli - during a task designed to measure the effect of covariation bias and its emotional response consequences. Event-related potentials (ERPs) were recorded while participants ( = 52) were presented with a pre-stimulus cue that either conveyed information about the valence of an upcoming emotional image, or left them in ambiguity. We replicated findings that demonstrate expectancy biases in a priori and online expectancies of emotion-eliciting images, as well as in a posteriori estimates for concurrence of uncertainty cues and aversive images. Moreover, we demonstrate a novel finding that uncertainty cues amplify the LPP in response to subsequent aversive emotional stimuli. These findings advance research by conjoining existing emotion regulation research on the LPP with study of the effects of uncertainty on emotional appraisal and highlight the importance of accounting for stimulus uncertainty in emotion regulation research.

The junction between memory dysfunction and socioaffective dysfunction is a complex area as research has typically been interested in one dysfunction rather than in the other. However, this junction can be studied under the lens of destination memory. Destination memory (i.e. the ability to remember to whom a piece of information was previously transmitted) is unique in that it draws on both memory and socioaffective processes. Research has demonstrated how destination memory is prone to distortions in neurological/psychiatric disorders. This paper aims to provide a focused review on the interplay between memory and socioaffective processes in the deterioration of destination memory within these disorders. It shows how both episodic memory and socioaffective dysfunction can jointly contribute to the decline in destination memory, although the contribution of each of the two factors may vary depending on the disorder.

Implicit emotion regulation provides an effective means of controlling emotions triggered by a single face without conscious awareness and effort. Crowd emotion has been proposed to be perceived as more intense than it actually is, but it is still unclear how to regulate it implicitly. In this study, participants viewed sets of faces of varying emotionality (e.g. happy to angry) and estimated the mean emotion of each set after being primed with an expressive suppression goal, a cognitive reappraisal goal, or a neutral goal. Faster discrimination for happy than angry crowds was observed. After induction of the expressive suppression goal instead of the cognitive reappraisal goal, augmented N170 and early posterior negativity (EPN) amplitudes, as well as attenuated late positive potential (LPP) amplitudes, were observed in response to happy crowds compared to the neutral goal. Differential processing of angry crowds was not observed after the induction of both regulatory goals compared to the neutral goal. Our findings thus reveal the happy-superiority effect and that implicit induction of expressive suppression improves happy crowd emotion recognition, promotes selective coding, and successfully downregulates the neural response to happy crowds.

Social influence plays a crucial role during the teen years, with adolescents supposedly exhibiting heightened sensitivity to their peers. In this study, we examine how social influence from different sources, particularly those with varying normative and informational significance, affect adolescents' opinion change. Furthermore, we investigated the underlying neural dynamics to determine whether these two behaviorally similar influences share their neural mechanisms. Twenty-three participants (14-17 years old) gave their opinions about facial stimuli and received feedback from either a peer group or an expert group, while brain responses were recorded using concurrent magnetoencephalography. In a second rating session, we found that participants' opinions changed in line with conflicting feedback, but only when the feedback was lower than their initial evaluation. On the neural level, conflict with peers evoked stronger neural responses than conflict with experts in the 230-400 ms time window and the right frontotemporal magnetometer channels. Nevertheless, there was no greater conformity toward peers. Moreover, conflict compared to no conflict decreased neural oscillations in the beta frequency range (20-26 Hz) at the right frontal and parietal channels. Taken together, our findings do not support the general assumption that adolescent behavior is excessively vulnerable to peer norms, although we found heightened neural sensitivity to peer feedback.

Sociocognitive impairment is well known in the relapsing-remitting form of multiple sclerosis (RR-MS). The purpose of the present study was to assess explicit and implicit humor abilities in this population. Based on clinical observation and contrary to the current cognitive model, we hypothesized that implicit performances (happy facial expressions) would be better than explicit ones (humor judgment assessed by explicit humor comprehension, subjective feeling of amusement as a conscious appreciation of funniness, and verbal justifications of funniness). Twenty-five RR-MS patients and twenty-five healthy participants completed the tasks. Their face was filmed during humor ratings. Patients' results suggest that 32% of them showed an impairment in explicit humor comprehension, with normal facial expressions. Both groups found great difficulty in justifying the cause of their amusement. All these results may suggest the existence of a supplementary implicit pathway in humor processing. The preservation of this implicit pathway may be advantageous for future remediation. Contrary to the current model, we found that the subjective feeling of amusement was preserved when comprehension was impaired. Further studies will be needed to clarify this component, and adjust the theoretical modeling.

Professional pride, including self-reflection and attitude toward one's own occupational group, induces individuals to behave in socially appropriate ways, and uniforms can encourage wearers to have this pride. This study was to elucidate the working pattern of professional pride by exploring neural responses when wearing uniforms and being conscious of a third-person's perspective. Twenty healthy adults who had an occupation requiring uniforms were scanned using functional MRI with a self-evaluation task consisting of 2 [uniform versus casual wear] × 2 [first-person perspective versus third-person perspective] conditions. The neural effects of clothing and perspective were analyzed and post-hoc tests were followed. The interaction effect was displayed in the bilateral dorsomedial prefrontal cortex, where uniform led to higher activity in third-person perspective than in first-person perspective, whereas casual wear led to the opposite pattern, suggesting this region may be involved in the awareness of third-person's perspective to uniform-wearing. The right dorsomedial prefrontal cortex showed functional connectivity with the right posterior superior temporal sulcus in uniform-third-person perspective compared to uniform-first-person perspective, suggesting this connection may work for processing information from third-person perspective in a uniform-wearing state. Professional pride may prioritize social information processing in third-person perspective rather than self-referential processing in first-person perspective.

Public facilities that have NIMBY (not in my backyard) structure involve both a social dilemma, in which individuals' decisions to prevent the worst outcomes for themselves undermine the public interest, and a moral dilemma focused on the majority versus the minority. This study examined the cognitive-neural processes in judging whether to prioritize the site residents or the citizenry as a whole within the context of NIMBY. Our ROIs were the right angular gyrus being related to concern about the worst possible outcomes for others and oneself, the amygdala associating with emotional aversion to prioritizing the majority, and the vmPFC, which integrates the aversion into "all things considered" judgments. As a result of comparing ingroup conditions for which a NIMBY facility may make participants worst-off position and outgroup conditions for which this possibility is denied, the right angular gyrus was activated in both conditions. The amygdala was activated only in the ingroup, and the vmPFC exhibited a stronger tendency in the ingroup. We concluded that the cognitive-neural processes in judgments on NIMBY facilities are common to both decision-making to avoid the worst-off position for others and for oneself and moral judgments between the majority and the minority.

This Event-Related Potential (ERP) study aimed to test how habitual and short-term violent video game exposure (VVGE) may affect empathy for pain responses in adolescents. In a within-subjects design, boys ( = 56; aged 12-16 years) performed a pain judgment task before and immediately after playing a violent video game. In this task, participants judged whether photos of hands depicted on their screen were in a painful situation or not. While both the P3 and the LPP components were not related to habitual violent video game exposure, general exposure to antisocial media content predicted lower P3 amplitudes to painful pictures. Further, 40 min of violent gameplay did not affect the P3 responses; however, it temporarily decreased LPP responses to painful pictures, suggesting a modest short-term desensitization effect. However, this latter interpretation is limited by a strong LPP pain effect - a significant amplitude difference between painful and non-painful pictures - that remained present in the post-game condition. Such persistent LPP effect may relate to the notion that adolescents are still learning how to properly regulate their emotional reactions. This study contributes to the limited literature on violent video games' desensitization in adolescents' brains, opening new avenues for media violence research.

Environmental factors, such as culture, are known to shape individual variation in brain activity including spontaneous activity, but less is known about their population-level effects. Eastern and Western cultures differ strongly in their cultural norms about relationships between individuals. For example, the collectivism, interdependence and tightness of Eastern cultures relative to the individualism, independence and looseness of Western cultures, promote interpersonal connectedness and coordination. Do such cultural contexts therefore influence the group-level variability of their cultural members' spontaneous brain activity? Using novel methods adapted from studies of inter-subject neural synchrony, we compare the group-level variability of resting state EEG dynamics in Chinese and Canadian samples. We observe that Chinese subjects show significantly higher inter-subject correlation and lower inter-subject distance in their EEG power spectra than Canadian subjects, as well as lower variability in theta power and alpha peak frequency. We demonstrate, for the first time, different relationships among subjects' resting state brain dynamics in Chinese and Canadian samples. These results point to more idiosyncratic neural dynamics among Canadian participants, compared with more shared neural features in Chinese participants.

Successful face recognition is important for social interactions and public security. Although some preliminary evidence suggests that anodal and cathodal transcranial direct current stimulation (tDCS) might modulate own- and other-race face identification, respectively, the findings are largely inconsistent. Hence, we examined the effect of both anodal and cathodal tDCS on the recognition of own- and other-race faces. Ninety participants first completed own- and other-race Cambridge Face Memory Test (CFMT) as baseline measurements. Next, they received either anodal tDCS, cathodal tDCS or sham stimulation and finally they completed alternative versions of the own- and other-race CFMT. No difference in performance, in terms of accuracy and reaction time, for own- and other-race face recognition between anodal tDCS, cathodal tDCS and sham stimulation was found. Our findings cast doubt upon the efficacy of tDCS to modulate performance in face identification tasks.

Of late, internet addiction among adolescents has become a serious problem, with increased internet use. Previous research suggests that the more people become addicted to the internet, the more they isolate themselves from society. Conversely, it has been suggested that abundant social capital (the networks of relationships among people who live and work in a particular society) protects people from becoming addicted to the internet. This study focused on the brain structure of typical adolescents (10-18 years of age) and hypothesized that the size of the left dorsolateral prefrontal cortex (DLPFC), which is thought to be associated with self-control ability, is associated with both internet addiction and social capital. Voxel-based morphometry analysis indicated that left DLPFC volume was negatively correlated with the severity of internet addiction and positively correlated with social capital. Furthermore, correlation analysis demonstrated that the severity of internet addiction and social capital were negatively correlated. The statistical association between them was no longer significant when left DLPFC volume was used as a control variable. These results suggest that the left DLPFC may mediate the relationship between social capital and internet addiction in adolescents.

Children with autism often have difficulty with Theory of Mind (ToM), the ability to infer mental states, and pragmatic skills, the contextual use of language. Neuroimaging research suggests ToM and pragmatic skills overlap, as the ability to understand another's mental state is a prerequisite to interpersonal communication. To our knowledge, no study in the last decade has examined this overlap further. To assess the emerging consensus across neuroimaging studies of ToM and pragmatic skills in autism, we used coordinate-based activation likelihood estimation (ALE) analysis of 35 functional magnetic resonance imaging (MRI) studies (13 pragmatic skills, 22 ToM), resulting in a meta-analysis of 1,295 participants (647 autistic, 648 non-autistic) aged 7 to 49 years. Group difference analysis revealed decreased left inferior frontal gyrus (LIFG) activation in autistic participants during pragmatic skills tasks. For ToM tasks, we found reduced anterior cingulate cortex (ACC), medial prefrontal cortex (MPFC), and temporoparietal junction (TPJ) activation in autistic participants. Collectively, both ToM and pragmatic tasks showed activation in IFG and superior temporal gyrus (STG) and a reduction in left hemispheric activation in autistic participants. Overall, the findings underscore the cognitive and neural processing similarities between ToM and pragmatic skills, and their underlying neurobiological differences in autism.
