Social behavior is affected by social structure type, but how neural function changes with social type remains unclear. We investigated whether social group size affects social behaviors based on dopamine (DA) and serotonin (5-HT) systems. Four-week-old male mice were housed under different social group sizes: one, two, four, and eight mice per cage (1mpc, 2mpc, 4mpc, 8mpc, respectively). After 4 weeks, social preference, social interaction, and forced swim tests were performed to test sociability and anxiety, respectively, followed by analysis of DA and 5-HT and their metabolites (3,4-dihydroxyphenylacetic acid [DOPAC], 3-methoxytyramine [3-MT], norepinephrine, and 5-hydroxyindoleacetic acid [5-HIAA]). Social interactions and anxious behavior decreased with increased social group size. DA, 3-MT, and 5-HT levels decreased with increasing social group size, whereas DOPAC and 5-HIAA levels increased in the extended mesocorticolimbic system, including the dorsal striatum. Moreover, the increased social group size resulted in increased DOPAC/DA and 5-HIAA/5-HT ratios, accompanied by a decrease in the 3-MT/DA ratio within the extended mesocorticolimbic system. Linear regression analysis also revealed that social group size affects DA and 5-HT turnover. These suggest that social group size may influence behavior and monoamine levels, potentially contributing to DA- and 5-HT-related psychiatric disorders.

The chicken game, a well-established social dilemma paradigm, is widely used to study cooperative and competitive behaviors. Strategic decision-making in this game is influenced by the outcomes of cooperative and competitive interactions, with feedback-related event-related potentials (ERPs) during the feedback phase being a primary research focus. However, it remains unclear whether specific ERP components associated with strategic decision-making are present during the response phase. This study implemented a computerized chicken game featuring two cars - one representing the participant and the other the opponent - driving toward each other. Players chose to "give way" or "go straight," with the opponent's decisions controlled by a computer under high-cooperation (70% "give way") and low-cooperation (30% "give way") conditions. Participants made their choices via key presses, and outcomes were presented during the feedback phase. Results revealed a readiness potential (RP) during the response phase, with increased RP amplitudes observed when participants could not accurately predict the opponent's choice, regardless of cooperation condition. These findings suggest that the RP component reflects strategic adjustments and decision-making processes in social dilemmas, providing a potential ERP marker for such contexts.

This hyperscanning study explored the electrophysiological (EEG) patterns of dyads during a naturalistic persuasive interaction, in which the persuader had to convince the receiver that choosing a group solution was the most effective way to solve a group hypothetical everyday situation. Fifteen dyads composed of a persuader and a receiver were involved in a persuasive interaction while EEG data were recorded. EEG frequency bands (delta, theta, alpha, beta and gamma bands) were analyzed, first, considering the distinct role of the participants and, second, dividing the dyads according to the perceived effectiveness of persuasion. The intra-brain results showed greater activation of the delta, theta and alpha bands in the frontal area of the persuader compared to the receiver. The inter-brain analyses reported a significantly increased dissimilarity activation for delta and theta band in the frontal area compared to more temporo-central and parieto-occipital regions, regardless of the perceived effectiveness of persuasion. To summarize, the process of enhancing groupness during a persuasive interaction generates in the persuader a specific EEG pattern involving mainly low frequency bands activation in the frontal brain regions, suggesting a significant attentional effort and emotional involvement.

Neural reactions to others' pain are usually lower when the individual is of a different ethnicity than when they are of the same ethnicity. This suggests that empathy is not only an automatic phenomenon but also a motivated one. In the present study, we tested whether one's willingness to increase or decrease empathy would correspondingly increase or decrease the neural empathic response, as measured with electroencephalography (EEG), irrespective of ethnicity. In Study 1, participants were presented with pictures displaying painful or non-painful stimulations on an individual from a similar or different ethnic group. In Study 2, the procedure was relatively similar but employed a within-subject design and was conducted in two countries: Belgium and Rwanda. Overall, EEG results showed that participants successfully increased their neural response to the pain of others, irrespective of the others' ethnicity in Study 1. However, the within-subject design used in Study 2 revealed additional nuances, as we observed that participants increased their neural pain response selectively toward ingroup individuals. Our findings indicate that observing the pain of a single person, regardless of ethnicity, can heighten one's neural reaction. Yet, when both ingroup and outgroup members are present, the neural response intensifies only for ingroup members.

Several studies showed a positive effect of stories on Theory of Mind (ToM) performance. The aim of the present exploratory study was to investigate whether and how a specific aspect of narrative, i.e., character perspective, modulates the brain activation in response to a ToM task and improve the accuracy. Fifty participants were divided in three groups based on the text assigned: first-person perspective group (1 G; = 16), third-person perspective group (3 G; = 18) and a scientific essay group (EG; = 16). The electroencephalographic and behavioral responses to eyes expressions, taken from the "Reading the Mind in the Eyes" test, were recorded pre-(T0) and post-(T1) reading task. The main results showed a greater N100 on left fronto-central electrodes and a greater P220-400 on right temporo-parietal electrodes in response to eye expressions at T1 compared to T0 in 3 G. A lower N220-400 was found on right fronto-central in response to eye expressions at T1 compared to T0 in 1 G and 3 G. The results suggest that, although reading first- and third-person stories modulates self-processes in a similar way, third-person stories involve an early stage of processing and a more extended neural network including anterior-posterior brain sites.

Despite its importance for daily social interactions, few studies have explored interindividual differences in the Theory of Mind (ToM) abilities of healthy adults. We used Children's False-Attribution (CFA), Children's False-Beliefs (CFB), and Belief-Desire Reasoning tasks, along with fMRI-based assessments, in a comparative analysis of ToM among primary school teachers (PST; = 27), skilled in social interactions with children, and matched controls (MC; = 24), who lacked such experience. PST demonstrated slower reaction times than MC in Adult and Child false-belief stories of CFB. However, no other behavioral differences between the groups and between-group differences were observed at the brain level. Both groups presented similar valence ratings for stories in the CFA. Notably, fMRI analysis revealed a group-by-condition interaction effect in the right lateral orbitofrontal cortex (OFC). In PSTs, OFC activation decreased during negative false-attribution stories regarding children compared to stories related to adults, whereas MC demonstrated an opposite activation pattern. Between-group differences in right lateral OFC activity possibly signify a neural efficiency effect secondary to frequent social interactions of PSTs, unlike the MCs, with children in the working environment. These results underscore the significance of everyday social experiences in the functional plasticity of ToM networks.

Social attention, an important mechanism that orients people to social cues, is critical for the development of higher-ordered features of social cognition. Both endogenous (i.e. automatic and undirected) and exogenous (i.e. purposeful and directed) social attention is important for processing social features, yet there is limited work systematically addressing how different experimental manipulations modulate social attention. This study examined how endogenous and exogenous manipulations of a classic face inversion task influence ERP activity in adults ( = 71) and adolescent youth ( = 65). Results from Study 1 indicated a lack of task differences for P1 and N170 but a larger inversion effect for P3 when a social perceptual decision was required. Study 2 demonstrated developmental differences in the youth, such that youth and adults had opposite inversion effects for N170 and youth had no effect for the P3. These findings indicate that face perception neural markers are sensitive to exogenous decisions, with development still active in adolescence. This is important to consider when designing future studies, as task-based decisions may alter the neural responses to faces differentially by age.

This study investigated the impact of social isolation in Carioca High-Conditioned Freezing (CHF) rats, an animal model of generalized anxiety disorder (GAD). Animals selected for high (CHF), low trait anxiety (Carioca Low-Conditioned Freezing, CLF), and control rats from randomly bred populations (CTL) were housed in groups or kept isolated in their cages for 14 consecutive days. On the fifteenth day, all animals underwent the Forced Swimming Test (FST), where the latency to immobility was assessed as a depressive-like measure. Under standard grouping conditions, CHF rats showed a shorter latency to immobility in the FST compared to CTL and CLF animals, indicating depressive-like characteristics and possible GAD comorbidity. Social isolation decreased the latency to immobility in CLF and CTL animals, while it paradoxically increased this measure in CHF animals. Therefore, social isolation exerted a depressive-like action in CTL and CLF rats, but had a protective or "antidepressant-like" effect in CHF animals. Since, CHF rats are housed with other animals with high trait anxiety, such protective action induced by social isolation might have been due to the mitigation of what has been referred to as "social stress contagion". These results are discussed regarding the association between depressive-like behaviors and reduced social engagement.

The dissolving of social bonds is disruptive and leads to increased stress responsivity and a strong desire for reunion. The oxytocin (OXT) system is critical for the formation of social attachments, such as pair bonds, and is also involved in social recognition, social memory, and social vigilance. Therefore, long-term changes in the OXT system resulting from cohabitation and pair bonding may contribute to reunion-seeking behavior. Here, we employed social conditioned place preference (SCPP) and the forced swim test (FST) to examine sensitivity to partner-associated contexts and passive stress coping following a period of partner separation. We found that opposite-sex cohabitation led to SCPP formation only in male prairie voles with a strong preference for their partner, and this SCPP was maintained following short-term loss of a pair bonded partner. Furthermore, pair bonded males that were separated from their partner displayed more passive stress-coping than those that were not bonded to their lost partner, suggesting that differences in prairie vole mating tactics (i.e. formation of a bond or not) influence the behavioral response to partner separation. Finally, we found changes in OXTR binding that may reflect variation in loss-related behavioral phenotypes based on different mating strategies.

The transition to parenthood requires parents develop caregiving behaviors, such as the ability to identify their infant's emotions and regulate their own emotional response. Research has identified patterns of neural activation in parenting contexts that are interpreted as socioemotional processing. However, no prior research has directly tested whether mothers' neural responses to their infant's affect are the same as those involved in emotion perception/experience and regulation in other contexts. We employed conjunction analyses to clarify which components of mothers' neural response to viewing their infant's affect are shared with passively viewing and labeling adult affective faces (emotion perception/experience and implicit emotion regulation, respectively) in 24 mothers three months postpartum. Our results support a common neural response to viewing infant and adult affect in regions associated with emotion perception/experience (bilateral hippocampi, amygdalae, thalami, orbitofrontal cortex, and ventrolateral prefrontal cortex), but no areas of common response to viewing negative infant affect and implicitly regulating negative adult affect outside of the occipital lobe and cerebellum. This study provides corroborating evidence for shared neural patterns being involved in perceiving/experiencing infant and adult affect but not implicit regulation of infant and adult negative affect.

Humans are social creatures, and many tasks in our daily lives are solved together. The two main forms of social interaction in problem solving could be defined as competition and cooperation. In our study, we compared the ERS/ERD when performing a creative task (Alternative Uses Test, AUT) and a control task ("naming the objects from the presented category") under competitive conditions in dyads (22 dyads, m-m, f-f, 18-23 years old) compared to the performance of tasks individually. The number of answers given by subjects under competitive conditions was significantly lower than during the execution of the tasks individually. The solving of the creative task in competition versus individual performance was accompanied by EEG synchronization (9-30 hz) clusters: 140-1220 ms and 900-1780 ms after stimulus presentation; 13.5-30 hz (1800-1980 ms), reflecting the creative thinking mode, and expected cognitive, emotional answers' assessment. The control task under competitive conditions was accompanied by pronounced synchronization of low frequencies in the frontal areas (2-7 hz, 0-1980 ms), due to a greater working memory load; synchronization clusters in broadband (10-30 hz, 100-320 ms, 400-860 ms) and in the beta EEG band (17-30 hz, 1140-1980 ms). The competitive conditions significantly modulated the brain activity underlying creative and non-creative cognitive task performance, and resulted in greater induced EEG synchronization.

The aim of the study is to understand how Mirror Neuron System (MNS) and Mentalizing Network (MZN) interact with each other. EEG data was collected during a photo judgment task with pictures of actions or facial expressions. Participants ( = 30, 63% women) were asked to either identify how the shown action/expression was being performed (MNS) or what the goal or intention behind the action was (MZN). Data were analyzed using microstate analysis, source localization and Event-Related Potentials. When comparing the action types, we found early divergence between the brain states of MNS and MZN when comparing the same action type. There was temporal alignment between the start and end time of the induced microstates, among the same action type. Between different action types, the timing was slightly shifted. Temporally, there was a greater overlap between the timing of the states between networks within the same action type as compared to within networks across action types. The MNS and MZN are acting in parallel rather then subsequently and possibly feed into each other. Furthermore, the MNS and MZN do not specifically react to one action type over the other, but their activity is influenced by the action type.

We systematically investigated the application of embodied hyperscanning methodologies in social neuroscience research. Hyperscanning enables the simultaneous recording of neurophysiological and physiological signals from multiple participants. We highlight the trend toward integrating Mobile Brain/Body Imaging (MoBI) within the 4E research framework, which emphasizes the interconnectedness of brain, body, and environment. Our analysis revealed a geographic concentration of studies in the Global North, calling for global collaboration and transcultural research to balance the field. The predominant use of Magneto/Electroencephalogram (M/EEG) in these studies suggests a traditional brain-centric perspective in social neuroscience. Future research directions should focus on integrating diverse techniques to capture the dynamic interplay between brain and body functions in real-world contexts. Our review also finds a preference for tasks involving natural settings. Nevertheless, the analysis in hyperscanning studies is often limited to physiological signal synchrony between participants. This suggests a need for more holistic and complex approaches that combine inter-corporeal synchrony with intra-individual measures. We believe that the future of the neuroscience of relationships lies in embracing the complexity of cognition, integrating diverse methods and theories to enrich our grasp of human social behavior in its natural contexts.

Empathy requires the ability to understand another's point of view and is critical for motivating a person to help others. However, little is known about the link between experiences of empathic emotional engagement in close friendships during adolescence and neural correlates of empathy in adulthood. Beginning in 1998, = 88 participants drawn from a demographically diverse community sample were observed annually from ages 13 to 21 and rated on the amount of emotional engagement displayed toward a close friend during a support task. At approximately age 24, participants underwent functional brain imaging while a partner or stranger was under distress. Contrary to predictions, greater emotional engagement with close friends during adolescence corresponded prospectively with temporal pole activity (a region associated with cognitive empathy and perspective taking) while observing threats directed at others. Results have implications for understanding the neurodevelopmental roots of empathy.

We investigated neural correlates of Emotion Recognition Accuracy (ERA) using the Assessment of Contextualized Emotions (ACE). ACE infuses context by presenting emotion expressions in a naturalistic group setting and distinguishes between accurately perceiving intended emotions (signal), and bias due to perceiving additional, secondary emotions (noise). This social perception process is argued to induce perspective taking in addition to pattern matching in ERA. Thirty participants were presented with an fMRI-compatible adaptation of the ACE consisting of blocks of neutral and emotional faces in single and group-embedded settings. Participants rated the central character's expressions categorically or using scalar scales in consequent fMRI scans. Distinct brain activations were associated with the perception of emotional vs. neutral faces in the four conditions. Moreover, accuracy and bias scores from the original ACE task performed on another day were associated with brain activation during the scalar (vs. categorical) condition for emotional (vs. neutral) faces embedded in group. These findings suggest distinct cognitive mechanisms linked to each type of emotional rating and highlight the importance of considering cognitive bias in the assessment of social emotion perception.

Being touched by others (social-touch) and touching oneself (self-touch) are common nonverbal behaviors in everyday interaction. The commonalities and differences between these two types of touching behavior are of particular interest for conditions when social-touch is substantially restricted such as during the corona pandemic. Neuropsychologically, pleasant social-touch is associated with increased activation in frontal brain regions such as frontopolar, dorsolateral prefrontal (dlPFC), and orbitofrontal cortices (OFC). However, for these regions a deactivation has also been reported. Likewise, for self-touch the findings are controversial. Therefore, the aim of this study is to shed light on the controversial findings and to elucidate the relation between self-touch and social-touch. From 2021 to 2022, in a quasi-naturalistic setting, in forty-six participants brain oxygenation and deoxygenation was examined during social-touch and self-touch in frontal cortices applying functional NearInfraRed Spectroscopy (fNIRS). Social-touch compared to self-touch led to a significantly higher brain deoxygenation in the frontopolar areas and in parts of the dlPFC and OFC. In contrast, brain oxygenation in the PFC was significantly increased during self-touch compared to social-touch. The cerebral activation and deactivation pattern in a quasi-naturalistic setting indicates that self-touch cannot achieve the hedonic effects of social-touch, but it can influence internally self-regulating processes.

It is well established that the Self has a unique representation in the social brain, as evident from the Self-Referential Effect (SRE). However, the timing and neural mechanisms underlying the representation of individuals with varying degrees of closeness and emotional relevance to the Self remain unclear. Twenty-two participants read 260 personality traits and decided whether they described themselves, a close friend, or an admired celebrity. A strong Self-Referential Effect (SRE) was found at behavioral, ERP, and neuroimaging levels. Three anterior ERP components were identified as sensitive to social information: a P200 (250-350 ms) responding to famous others' traits, a P600 (500-700 ms) responding to self-trait processing, and a late positivity (800-950 ms) responding to self-trait processing and close traits. Source reconstructions revealed partially overlapping but distinct neural sources for each individual. The right precuneus (bodily self) and inferior frontal areas (inner voice) were active only during self-processing, while the right medial prefrontal cortex (BA10) was consistently active across tasks, showing a robust SRE. These findings provide insights into the neural mechanisms underlying the representation of the Self in social contexts.

The current study explored associations between testosterone, cortisol, and both the Levenson Self-Report Psychopathy Scale (LSRPS) and the Inventory of Callous Unemotional (ICU) traits. Data were gathered from a relatively large sample of university students ( = 522) and analyses considered direct and interactive associations between hormones and psychopathic traits, as well as interactions between these associations and the time of day at which samples were gathered and the sex of participants. Baseline cortisol had a negative association with LSRPS primary psychopathy scores. In addition, baseline cortisol interacted with the time of day in association with LSRPS total scores. Simple slopes analyses indicated cortisol had a negative association with LSRPS total scores in the morning but not the afternoon. Interactions among hormone measures were not statistically significant. There was also no evidence for the moderation of associations between hormones and psychopathic traits by sex.

Social neuroscientists often use magnetic resonance imaging (MRI) to understand the relationship between social experiences and their neural substrates. Although MRI is a powerful method, it has several limitations in the study of social experiences, first and foremost its low ecological validity. To address this limitation, researchers have conducted multimethod studies combining MRI with Ecological Momentary Assessment (EMA). However, there are no existing recommendations for best practices for conducting and reporting such studies. To address the absence of standards in the field, we conducted a systematic review of papers that combined the methods. A systematic search of peer-reviewed papers resulted in a pool of 11,558 articles. Inclusion criteria were studies in which participants completed (a) Structural or functional MRI and (b) an EMA protocol that included self-report. Seventy-one papers met inclusion criteria. The following review compares these studies based on several key parameters (e.g., sample size) with the aim of determining feasibility and current standards for design and reporting in the field. The review concludes with recommendations for future research. A special focus is given to the ways in which the two methods were combined analytically and suggestions for novel computational methods that could further advance the field of social neuroscience.
