Social cognitive neuroscience: a review of core processes

Emotion Recognition in Immersive Virtual Reality: From Statistics to Affective Computing

Emotions play a critical role in our daily lives, so the understanding and recognition of emotional responses is crucial for human research. Affective computing research has mostly used non-immersive two-dimensional (2D) images or videos to elicit emotional states. However, immersive virtual reality, which allows researchers to simulate environments in controlled laboratory conditions with high levels of sense of presence and interactivity, is becoming more popular in emotion research. Moreover, its synergy with implicit measurements and machine-learning techniques has the potential to impact transversely in many research areas, opening new opportunities for the scientific community. This paper presents a systematic review of the emotion recognition research undertaken with physiological and behavioural measures using head-mounted displays as elicitation devices. The results highlight the evolution of the field, give a clear perspective using aggregated analysis, reveal the current open issues and provide guidelines for future research.

Neuroscience and the Social Origins of Moral Behavior: How Neural Underpinnings of Social Categorization and Conformity Affect Everyday Moral and Immoral Behavior

Neuroscientific evidence identifies the brain networks and cognitive processes involved in people’s thoughts and feelings about their behavior. This helps individuals understand the judgments and decisions they make with regard to their own and others’ moral and immoral behavior. This article complements prior reviews by focusing on the social origins of everyday moral and immoral behavior and reviewing neuroscientific research findings related to social conformity, categorization, and identification to demonstrate (a) when people are motivated by social norms of others to follow particular moral guidelines, (b) what prevents people from considering the moral implications of their actions for others, and (c) how people process feedback they receive from others about the appropriateness of their behavior. Revealing the neural mechanisms involved in the social processes that influence the moral and immoral behaviors people display helps researchers understand why and when different types of interventions aiming to regulate moral behavior are likely to be successful or unsuccessful.

Implicit and Explicit Mentalizing Deficits in Adolescent Inpatients: Specificity and Incremental Value of Borderline Pathology

Research has demonstrated mentalizing impairment associated with borderline personality disorder (BPD) in adolescents. However, mentalizing performance in adolescents with BPD has never been compared to that of psychiatric control and healthy control adolescents simultaneously. The present study aimed to (a) compare implicit and explicit mentalizing, and hypermentalizing errors in implicit mentalizing, across youth with BPD and psychiatric and healthy controls, and (b) evaluate the association of borderline features with mentalizing deficits over and above internalizing and externalizing. Psychiatric inpatients with BPD (n = 139), inpatient psychiatric controls (n = 310), and healthy adolescents (n = 134) completed two mentalizing tasks, an interview assessing BPD, and measures of psychopathology. Results showed that BPD specificity could be demonstrated only for implicit mentalizing and hypermentalizing. Explicit mentalizing deficits did not differ between BPD and psychiatric control groups. Borderline features had unique associations to implicit mentalizing and hypermentalizing, over and above internalizing and externalizing.

Social cognition and executive functions in children and adolescents with focal epilepsy

OBJECTIVES

Deficits in facial emotion recognition and Theory of Mind are frequent in patients with epilepsy. Although this evidence, studies on pediatric age are few and the relation between these abilities and other cognitive domain remains to be better elucidated. The purpose of our study is to evaluate facial emotion recognition and Theory of Mind in children and adolescents with focal epilepsy, and correlate them with intelligence and executive functions.

MATERIALS AND METHODS

Our work is a cross-sectional observational study. Sixty-two children and adolescents aged between 7-16 years diagnosed by focal epilepsy and 32 sex/age-matched controls were recruited. All participants were administered a standardized battery tests to assess social cognition (NEPSY-II), executive functions (EpiTrack Junior) and cognitive non-verbal level (Raven Progressive Matrices).

RESULTS

Emotion recognition mean score was significantly lower in the epilepsy group than in the controls to Student's t-test (p<0.05). Epilepsy group showed an impairment in happiness, sadness, anger and fear recognition, compared to controls (p<0.05). Theory of Mind mean score was also significantly lower in epilepsy group than controls (p<0.05). Deficits in emotion recognition seemed to be related to low age at onset of epilepsy, long duration of disease, low executive functions and low non-verbal intelligence. Deficits in Theory of Mind seemed to be related to a high seizure frequency.

CONCLUSIONS

Our results suggest that children and adolescents with focal epilepsy had deficit in facial emotion recognition and Theory of Mind, compared to their peer. Both these difficulties seem to be related to some features of epilepsy itself. Our results also suggest that deficits in facial emotion recognition are potentially related to difficulties in executive functions and non-verbal intelligence. More studies are needed to confirm these hypotheses.

Neural alignment during face-to-face spontaneous deception: Does gender make a difference?

This study investigated the gender differences in deception and their neural basis in the perspective of two‐person neuroscience. Both male and female dyads were asked to perform a face‐to‐face spontaneous sender–receiver deception task, while their neural activities in the prefrontal cortex (PFC) and right temporal parietal junction (rTPJ) were recorded simultaneously using functional near‐infrared spectroscopy (fNIRS)‐based hyperscanning. Male and female dyads displayed similar deception rate, successful deception rate, and eye contact in deception trials. Moreover, eye contact in deception trials was positively correlated with the success rate of deception in both genders. The fNIRS data showed that the interpersonal neural synchronization (INS) in PFC was significantly enhanced only in female dyads when performed the deception task, while INS in rTPJ was increased only in male dyads. Such INS was correlated with the success rate of deception in both dyads. Granger causality analysis showed that no significant directionality between time series of PFC (or rTPJ) in each dyad, which could indicate that sender and receiver played equally important role during deception task. Finally, enhanced INS in PFC in female dyads mediated the contribution of eye contact to the success rate of deception. All findings in this study suggest that differential patterns of INS are recruited when male and female dyads perform the face‐to‐face deception task. To our knowledge, this is the first interbrain evidence for gender difference of successful deception, which could make us a deeper understanding of spontaneous face‐to‐face deception.

The role of the subgenual anterior cingulate cortex in dorsomedial prefrontal-amygdala neural circuitry during positive-social emotion regulation

Positive-social emotions mediate one's cognitive performance, mood, well-being, and social bonds, and represent a critical variable within therapeutic settings. It has been shown that the upregulation of positive emotions in social situations is associated with increased top-down signals that stem from the prefrontal cortices (PFC) which modulate bottom-up emotional responses in the amygdala. However, it remains unclear if positive-social emotion upregulation of the amygdala occurs directly through the dorsomedial PFC (dmPFC) or indirectly linking the bilateral amygdala with the dmPFC via the subgenual anterior cingulate cortex (sgACC), an area which typically serves as a gatekeeper between cognitive and emotion networks. We performed functional MRI (fMRI) experiments with and without effortful positive-social emotion upregulation to demonstrate the functional architecture of a network involving the amygdala, the dmPFC, and the sgACC. We found that effortful positive-social emotion upregulation was associated with an increase in top-down connectivity from the dmPFC on the amygdala via both direct and indirect connections with the sgACC. Conversely, we found that emotion processes without effortful regulation increased network modulation by the sgACC and amygdala. We also found that more anxious individuals with a greater tendency to suppress emotions and intrusive thoughts, were likely to display decreased amygdala, dmPFC, and sgACC activity and stronger connectivity strength from the sgACC onto the left amygdala during effortful emotion upregulation. Analyzed brain network suggests a more general role of the sgACC in cognitive control and sheds light on neurobiological informed treatment interventions.

The role of alexithymia in social cognition: Evidence from a non-clinical population

BACKGROUND

Alexithymia is a personality construct characterised by difficulty in identifying and describing one's emotions. We investigated whether people with alexithymia, who struggle with emotion-processing abilities, have diminished emotion-related social cognitive competencies, where social cognition encompasses the set of abilities that allows one to navigate one's social environment.

METHODS

We assessed alexithymia and four components of social cognition: recognition of others' emotions, representation of others' affective and cognitive mental states, empathy, and regulation of one's own feelings. We investigated whether alexithymia could significantly predict each of these components, beyond the effect of other individual difference variables (i.e., anxiety/depressive symptoms), which have been previously associated with both social cognition and alexithymia. Two hundred six participants were recruited. Multiple hierarchical regression analyses were performed to assess the possible relationships between alexithymia and social cognition skills.

RESULTS

Alexithymia significantly predicted emotion recognition, empathy, and emotional regulation, even after controlling for the effect of potentially competing factors (i.e., anxiety/depressive symptoms). Alexithymia did not predict representation of others' affective and cognitive mental states.

LIMITATIONS

The present study adopted a cross-sectional design, which does not permit us to draw firm conclusions about the causality of the emergent relationships.

CONCLUSIONS

These data provide support for the argument that recognising others' emotions and feelings relies on the ability to identify correctly one's own feelings. Our results also indicate the importance of taking into consideration individual differences in levels of alexithymia when investigating social cognition in non-clinical populations, as alexithymia appears to be clearly related to social cognitive functioning.

Brain-to-Brain Coupling in the Gamma-Band as a Marker of Shared Intentionality

Cooperation and competition are two ways of social interaction keys to life in society. Recent EEG-based hyperscanning studies reveal that cooperative and competitive interactions induce an increase in interbrain coupling. However, whether this interbrain coupling effect is just a reflection of inter-subject motor coordination or can also signal the type of social interaction is unknown. Here, we show that behavioral coordination and social interaction type can be distinguished according to the frequency of oscillation in which the brains are coupled. We use EEG to simultaneously measure the brain activity of pairs of subjects, while they were performing a visual cue-target task in a cooperative and competitive manner. Behavioral responses were quasi-simultaneous between subject pairs for both competitive and cooperative conditions, with faster average response times for the competitive condition. Concerning brain activity, we found increased interbrain coupling in theta band (3–7 Hz) during cooperation and competition, with stronger coupling during competitive interactions. This increase of interbrain theta coupling correlated with a decrease in reaction times of the dyads. Interestingly, we also found an increase in brain-to-brain coupling in gamma band (38–42 Hz) only during cooperative interactions. Unlike the theta coupling effect, the gamma interbrain coupling did not correlate with dyads’ reaction times. Taken together, these results suggest that theta interbrain coupling could be linked to motor coordination processes common to cooperative and competitive interactions, while gamma brain-to-brain coupling emerges as an electrophysiological marker of shared intentionality during cooperative interactions.

Facial Emotion Recognition in Children and Adolescents with Specific Learning Disorder

BACKGROUND

Some recent studies suggest that children and adolescents with different neurodevelopmental disorders perform worse in emotions recognition through facial expressions (ER) compared with typically developing peers. This impairment is also described in children with Specific Learning Disorders (SLD), compromising their scholastic achievement, social functioning, and quality of life. The purpose of our study is to evaluate ER skills in children and adolescents with SLD compared to a control group without learning disorders, and correlate them with intelligence and executive functions.

MATERIALS AND METHODS

Our work is a cross-sectional observational study. Sixty-three children and adolescents aged between 8 and 16 years, diagnosed with SLD, and 32 sex/age-matched controls without learning disorders were recruited. All participants were administered standardized neuropsychological tests, evaluating facial emotion recognition (NEPSY-II), executive functions (EpiTrack Junior), and intelligence profile (WISC-IV).

RESULTS

Emotion recognition mean score was significantly lower in the SLD group than in the controls group on the Mann-Whitney U test for unpaired samples (p < 0.001). The SLD group performed significantly lower than the control group in their abilities to identify neutral expressions, happiness, sadness, anger, and fear compared to controls (p < 0.001). ER scores were positively correlated to the executive functions scores. There was no correlation with the Total Intelligence Quotient scores but there is a significant positive correlation with Working Memory Index and Processing Speed Index measured by WISC.IV.

CONCLUSION

Our study showed that children and adolescents with Specific Learning Disorders have facial emotion recognition impairment when compared with a group of peers without learning disorders. ER abilities were independent of their global intelligence but potentially related to executive functions.

Reflective function: A move to the level of concern

Reflective function (RF) is the capacity to reflect on one’s own thinking and feelings, as well as on that of others. It involves an increasingly complex awareness that there is more than what is visible on the surface. Most studies of RF have focused on its significance for self-development and interpersonal relationships in dyadic and family contexts. In this article, I suggest that by imparting a more accurate perception of the intra- and interpersonal reality and interrelatedness, RF is inextricably related to concern and to reaching others in widening circles. I further suggest that obstacles to its development and realization can be found at the individual, relational, and sociopolitical levels. I conclude that the construct of RF both captures and facilitates the connection between psychology and ethics, and that psychologists play a key role in exploring the conditions that affect the realization of RF, and in promoting social change in general.

Individual differences in envy experienced through perspective-taking involves functional connectivity of the superior frontal gyrus

Envy is the painful or resentful awareness of another’s advantage combined with a desire to possess that same advantage. Recent neuroscientific research has begun to shed light on the brain regions that process the experience of envy, including regions of the prefrontal cortex involved in emotional processing and social cognition. It is still unclear, however, which regions of the brain are functionally connected during the experience of envy. We recorded functional neuroimaging data while inducing simulated envy in participants, experienced through a perspective-taking hypothetical scenario task. In this task, participants took the perspective of a protagonist portrayed in a written description and compared themselves to either i) a self-similar/superior individual, ii) a self-dissimilar/superior individual, or iii) a self-dissimilar/average individual. During each comparison, participants also reported how much envy they experienced while taking the protagonists perspective. We demonstrate an inverse relationship in the connectivity of the left superior frontal gyrus to both the right supramarginal gyrus and the precuneus with respect to self-reported envy ratings across participants. In other words, we show that the greater the functional connectivity that the left superior frontal gyrus shares with the right supramarginal gyrus and precuneus, the less reported envy a participant experiences. Overall, our results are in line with previous research implicating the superior frontal gyrus in the reappraisal of negative emotions and extend these findings by showing this region is also involved in modulating the simulated experience of the social comparative, negative emotion of envy.

Putting the Nonsocial Into Social Neuroscience: A Role for Domain-General Priority Maps During Social Interactions

Whether on a first date or during a team briefing at work, people’s daily lives are inundated with social information, and in recent years, researchers have begun studying the neural mechanisms that support social-information processing. We argue that the focus of social neuroscience research to date has been skewed toward specialized processes at the expense of general processing mechanisms with a consequence that unrealistic expectations have been set for what specialized processes alone can achieve. We propose that for social neuroscience to develop into a more mature research program, it needs to embrace hybrid models that integrate specialized person representations with domain-general solutions, such as prioritization and selection, which operate across all classes of information (both social and nonsocial). To illustrate our central arguments, we first describe and then evaluate a hybrid model of information processing during social interactions that (a) generates novel and falsifiable predictions compared with existing models; (b) is predicated on a wealth of neurobiological evidence spanning many decades, methods, and species; (c) requires a superior standard of evidence to substantiate domain-specific mechanisms of social behavior; and (d) transforms expectations of what types of neural mechanisms may contribute to social-information processing in both typical and atypical populations.

A Review of the Existing and Emerging Topics in the Supply Chain Risk Management Literature

This review examines supply chain risk publications across nine prestigious management, operations, and supply chain journals with respect to exploring trends and emerging topics. Using a refined set of keywords, we extract and filter the most relevant supply chain risk management (SCRM) articles from Scopus between 2001 and 2019. Unlike previous reviews of the SCRM literature, our methodology utilizes both bibliometric and cocitation analyses of publications in selective management and operations and supply chain management journals. In addition to analyzing the current state of the SCRM literature via bibliometric analysis, we delve deeply into the clusters of literature informing SCRM studies through a cocitation analysis. By conducting a text analysis on these clusters, we identify the main themes and provide insights regarding article relevance, theoretical frameworks, and methodologies for each cluster. In addition, we categorize the themes within each cluster into three main groups of matured, developing, and emerging. Based on the identified categories, we provide detailed discussions on the promising avenues for research and practice in three main areas of sustainable SCRM, behavioral SCRM, and nascent methodologies and theories in SCRM studies. Finally, we dedicate a section in our review to discussing the direction of SCRM research during and after the coronavirus disease 2019 era.

Attributed social context and emotional content recruit frontal and limbic brain regions during virtual feedback processing

In communication, who is communicating can be just as important as what is said. However, sender identity in virtual communication is often inferred rather than perceived. Therefore, the present research investigates the brain structures activated by sender identity attributions and evaluative feedback processing during virtual communication. In a functional magnetic resonance imaging (fMRI) study, 32 participants were told that they would receive personality feedback, either sent from another human participant or from a randomly acting computer. In reality, both conditions contained random but counterbalanced feedback, automatically delivered by approving or denying negative, neutral, or positive adjectives. Although physically identical, feedback attributed to the "human" sender activated multiple regions within a "social brain" network, including the superior frontal, medial prefrontal, and orbitofrontal cortex, anterior and posterior parts of the cingulate cortex, and the bilateral insula. Regardless of attributed sender, positive feedback increased responses in the striatum and bilateral amygdalae, while negative compared to neutral feedback elicited stronger insula and somatosensory responses. These results reveal the recruitment of an extensive mentalizing and social brain network by mere sender attributions and the activation of brain structures related to reward and punishment by verbal feedback, demonstrating its embodied processing.

Validation of the ToMas-child Scale for the Assessment of the Theory of Mind in a Group of Spanish Speaking Children Aged 3 to 7 Years from Spain

This study aimed to determine the psychometric properties of the Theory of Mind assessment scale in children (ToMas-child). Two hundred and fifty-two Spanish children from 3 to 7 years were assessed in school settings. Rasch analysis showed the ToMas-child is a unidimensional scale valid for the assessment of the main components of the ToM in children. Data of hierarchical distribution of six items (seven tasks) are discussed as milestones in the latent construct of ToM development in childhood, and construct validity of the scale is examined. A reliability index of PSI = 0.7 indicated the usefulness of the scale as a screening tool.

The Mentalizing Approach to Psychopathology: State of the Art and Future Directions

Mentalizing is the capacity to understand others and oneself in terms of internal mental states. It is assumed to be underpinned by four dimensions: automatic–controlled, internally–externally focused, self–other, and cognitive–affective. Research suggests that mental disorders are associated with different imbalances in these dimensions. Addressing the quality of mentalizing as part of psychosocial treatments may benefit individuals with various mental disorders. We suggest that mentalizing is a helpful transtheoretical and transdiagnostic concept to explain vulnerability to psychopathology and its treatment. This review summarizes the mentalizing approach to psychopathology from a developmental socioecological evolutionary perspective. We then focus on the application of the mentalizing approach to personality disorders, and we review studies that have extended this approach to other types of psychopathology, including depression, anxiety, and eating disorders. We summarize core principles of mentalization-based treatments and preventive interventions and the evidence for their effectiveness. We conclude with recommendations for future research.

Social Safety Theory: A Biologically Based Evolutionary Perspective on Life Stress, Health, and Behavior

Social Safety Theory hypothesizes that developing and maintaining friendly social bonds is a fundamental organizing principle of human behavior and that threats to social safety are a critical feature of psychological stressors that increase risk for disease. Central to this formulation is the fact that the human brain and immune system are principally designed to keep the body biologically safe, which they do by continually monitoring and responding to social, physical, and microbial threats in the environment. Because situations involving social conflict, isolation, devaluation, rejection, and exclusion historically increased risk for physical injury and infection, anticipatory neural-immune reactivity to social threat was likely highly conserved. This neurocognitive and immunologic ability for humans to symbolically represent and respond to potentially dangerous social situations is ultimately critical for survival. When sustained, however, this multilevel biological threat response can increase individuals' risk for viral infections and several inflammation-related disease conditions that dominate present-day morbidity and mortality.

Attending to Eliza: rapid brain responses reflect competence attribution in virtual social feedback processing

In the age of virtual communication, the source of a message is often inferred rather than perceived, raising the question of how sender attributions affect content processing. We investigated this issue in an evaluative feedback scenario. Participants were told that an expert psychotherapist, a layperson or a randomly acting computer was going to give them online positive, neutral or negative personality feedback while high-density EEG was recorded. Sender attribution affected processing rapidly, even though the feedback was on average identical. Event-related potentials revealed a linear increase with attributed expertise beginning 150 ms after disclosure and most pronounced for N1, P2 and early posterior negativity components. P3 and late positive potential amplitudes were increased for both human senders and for emotionally significant (positive or negative) feedback. Strikingly, feedback from a putative expert prompted large P3 responses, even for inherently neutral content. Source analysis localized early enhancements due to attributed sender expertise in frontal and somatosensory regions and later responses in the posterior cingulate and extended visual and parietal areas, supporting involvement of mentalizing, embodied processing and socially motivated attention. These findings reveal how attributed sender expertise rapidly alters feedback processing in virtual interaction and have implications for virtual therapy and online communication.

Cognitive Flexibility Matters: The Role of Multilevel Positive Affect and Cognitive Flexibility in Shaping Victims’ Cooperative and Uncooperative Behavioral Responses to Trust Violations

Despite a significant growth in the scholarly literature in the area of trust violations and repair in the last decade, extant work has largely ignored the complex and socially competent responses of the victims of these violations. Our framework integrates insights from affective events theory, the broaden-and-build theory of positive emotions, and theories of cognitive processing to suggest that cognitive flexibility is central to understanding how individuals respond to trust violations. Rather than viewing victims solely as gatekeepers to trust repair, we examine how victims’ cognitive processes are influenced by the affective context of those violations, which can, in turn, produce a spectrum of nuanced behavioral responses. We refer to this spectrum as the “swollen middle,” the range of behavior that resides between the extremes of impulsive revenge and forgiveness-based, communal cooperation. By integrating psychological theories of emotion and cognitive processing, we seek to highlight the central role of cognitive flexibility in the range of cooperative responses to trust violations. More broadly, we seek to contribute to the emergence of a new paradigm for studying interpersonal trust at work—a paradigm that explores trust-violating events as situated affect-laden experiences that interact with relevant organizational and interpersonal factors to influence employee behavior and trust dynamics in organizations.

Functional brain network architecture supporting the learning of social networks in humans

Most humans have the good fortune to live their lives embedded in richly structured social groups. Yet, it remains unclear how humans acquire knowledge about these social structures to successfully navigate social relationships. Here we address this knowledge gap with an interdisciplinary neuroimaging study drawing on recent advances in network science and statistical learning. Specifically, we collected BOLD MRI data while participants learned the community structure of both social and non-social networks, in order to examine whether the learning of these two types of networks was differentially associated with functional brain network topology. We found that participants learned the community structure of the networks, as evidenced by a slower reaction time when a trial moved between communities than when a trial moved within a community. Learning the community structure of social networks was also characterized by significantly greater functional connectivity of the hippocampus and temporoparietal junction when transitioning between communities than when transitioning within a community. Furthermore, temporoparietal regions of the default mode were more strongly connected to hippocampus, somatomotor, and visual regions for social networks than for non-social networks. Collectively, our results identify neurophysiological underpinnings of social versus non-social network learning, extending our knowledge about the impact of social context on learning processes. More broadly, this work offers an empirical approach to study the learning of social network structures, which could be fruitfully extended to other participant populations, various graph architectures, and a diversity of social contexts in future studies.

Oxytocin Enhances an Amygdala Circuit Associated With Negative Symptoms in Schizophrenia: A Single-Dose, Placebo-Controlled, Crossover, Randomized Control Trial

Negative symptoms are core contributors to vocational and social deficits in schizophrenia (SZ). Available antipsychotic medications typically fail to reduce these symptoms. The neurohormone oxytocin (OT) is a promising treatment for negative symptoms, given its role in complex social behaviors mediated by the amygdala. In sample 1, we used a double-blind, placebo-controlled, crossover design to test the effects of a single dose of intranasal OT on amygdala resting-state functional connectivity (rsFC) in SZ (n = 22) and healthy controls (HC, n = 24) using a whole-brain corrected approach: we identified regions for which OT modulated SZ amygdala rsFC, assessed whether OT-modulated circuits were abnormal in SZ relative to HC on placebo, and evaluated whether connectivity on placebo and OT-induced connectivity changes correlated with baseline negative symptoms in SZ. Given our modest sample size, we used a second SZ (n = 183) and HC (n = 178) sample to replicate any symptom correlations. In sample 1, OT increased rsFC between the amygdala and left middle temporal gyrus, superior temporal sulcus, and angular gyrus (MTG/STS/AngG) in SZ compared to HC. Further, SZ had hypo-connectivity in this circuit compared to HC on placebo. More severe negative symptoms correlated with less amygdala-to-left-MTG/STS/AngG connectivity on placebo and with greater OT-induced connectivity increases. In sample 2, we replicated the correlation between amygdala-left-MTG/STS/AngG hypo-connectivity and negative symptoms, finding a specific association with expressive negative symptoms. These data suggest intranasal OT can normalize functional connectivity in an amygdala-to-left-MTG/STS/AngG circuit that contributes to negative symptoms in SZ.

The unique social sense of puerperium: Increased empathy and Schadenfreude in parents of newborns

Pregnancy and puerperium are typified by marked biobehavioral changes. These changes, which are traceable in both mothers and fathers, play an important role in parenthood and may modulate social cognition abilities. However, the latter effects remain notably unexplored in parents of newborns (PNs). To bridge this gap, we assessed empathy and social emotions (envy and Schadenfreude) in 55 PNs and 60 controls (childless healthy participants without a romantic relationship or sexual intercourse in the previous 48 hours). We used facial electromyography to detect physiological signatures of social emotion processing. Results revealed higher levels of affective empathy and Schadenfreude in PNs, the latter pattern being accompanied by increased activity of the corrugator suppercilii region. These effects were not explained by potential confounding variables (educational level, executive functioning, depression, stress levels, hours of sleep). Our novel findings suggest that PNs might show social cognition changes crucial for parental bonding and newborn care.

Incorporating methods and findings from neuroscience to better understand placebo and nocebo effects in sport

Placebo and nocebo effects are a factor in sports performance. However, the majority of published studies in sport science are descriptive and speculative regarding mechanisms. It is therefore not unreasonable for the sceptic to argue that placebo and nocebo effects in sport are illusory, and might be better explained by variations in phenomena such as motivation. It is likely that, in sport at least, placebo and nocebo effects will remain in this empirical grey area until researchers provide stronger mechanistic evidence. Recent research in neuroscience has identified a number of consistent, discrete and interacting neurobiological and physiological pathways associated with placebo and nocebo effects, with many studies reporting data of potential interest to sport scientists, for example relating to pain, fatigue and motor control. Findings suggest that placebos and nocebos result in activity of the opioid, endocannabinoid and dopamine neurotransmitter systems, brain regions including the motor cortex and striatum, and measureable effects on the autonomic nervous system. Many studies have demonstrated that placebo and nocebo effects associated with a treatment, for example an inert treatment presented as an analgesic or stimulant, exhibit mechanisms similar or identical to the verum or true treatment. Such findings suggest the possibility of a wide range of distinct placebo and nocebo mechanisms that might influence sports performance. In the present paper, we present some of the findings from neuroscience. Focussing on fatigue as an outcome and caffeine as vehicle, we propose three approaches that researchers in sport might incorporate in their studies in order to better elucidate mechanisms of placebo/nocebo effects on performance.

Uncovering complex central autonomic networks at rest: a functional magnetic resonance imaging study on complex cardiovascular oscillations

This study aims to uncover brain areas that are functionally linked to complex cardiovascular oscillations in resting-state conditions. Multi-session functional magnetic resonance imaging (fMRI) and cardiovascular data were gathered from 34 healthy volunteers recruited within the human connectome project (the '100-unrelated subjects' release). Group-wise multi-level fMRI analyses in conjunction with complex instantaneous heartbeat correlates (entropy and Lyapunov exponent) revealed the existence of a specialized brain network, i.e. a complex central autonomic network (CCAN), reflecting what we refer to as complex autonomic control of the heart. Our results reveal CCAN areas comprised the paracingulate and cingulate gyri, temporal gyrus, frontal orbital cortex, planum temporale, temporal fusiform, superior and middle frontal gyri, lateral occipital cortex, angular gyrus, precuneous cortex, frontal pole, intracalcarine and supracalcarine cortices, parahippocampal gyrus and left hippocampus. The CCAN visible at rest does not include the insular cortex, thalamus, putamen, amygdala and right caudate, which are classical CAN regions peculiar to sympatho-vagal control. Our results also suggest that the CCAN is mainly involved in complex vagal control mechanisms, with possible links with emotional processing networks.

Parallel distributed networks dissociate episodic and social functions within the individual

Association cortex is organized into large-scale distributed networks. One such network, the default network (DN), is linked to diverse forms of internal mentation, opening debate about whether shared or distinct anatomy supports multiple forms of cognition. Using within-individual analysis procedures that preserve idiosyncratic anatomical details, we probed whether multiple tasks from two domains, episodic projection and theory of mind (ToM), rely on the same or distinct networks. In an initial experiment (6 subjects, each scanned 4 times), we found evidence that episodic projection and ToM tasks activate separate regions distributed throughout the cortex, with adjacent regions in parietal, temporal, prefrontal, and midline zones. These distinctions were predicted by the hypothesis that the DN comprises two parallel, interdigitated networks. One network, linked to parahippocampal cortex (PHC), is preferentially recruited during episodic projection, including both remembering and imagining the future. A second juxtaposed network, which includes the temporoparietal junction (TPJ), is differentially engaged during multiple forms of ToM. In two prospectively acquired independent experiments, we replicated and triplicated the dissociation (each with 6 subjects scanned 4 times). Furthermore, the dissociation was found in all zones when analyzed independently, including robustly in midline regions previously described as hubs. The TPJ-linked network is interwoven with the PHC-linked network across the cortex, making clear why it is difficult to fully resolve the two networks in group-averaged or lower-resolution data. These results refine our understanding of the functional-anatomical organization of association cortex and raise fundamental questions about how specialization might arise in parallel, juxtaposed association networks.NEW & NOTEWORTHY Two distributed, interdigitated networks exist within the bounds of the canonical default network. Here we used repeated scanning of individuals, across three independent samples, to provide evidence that tasks requiring episodic projection or theory of mind differentially recruit the two networks across multiple cortical zones. The two distributed networks thus appear to preferentially subserve distinct functions.

Revisiting the Functional Anatomy of the Human Brain: Toward a Meta-Networking Theory of Cerebral Functions

For more than one century, brain processing was mainly thought in a localizationist framework, in which one given function was underpinned by a discrete, isolated cortical area, and with a similar cerebral organization across individuals. However, advances in brain mapping techniques in humans have provided new insights into the organizational principles of anatomo-functional architecture. Here, we review recent findings gained from neuroimaging, electrophysiological, as well as lesion studies. Based on these recent data on brain connectome, we challenge the traditional, outdated localizationist view and propose an alternative meta-networking theory. This model holds that complex cognitions and behaviors arise from the spatiotemporal integration of distributed but relatively specialized networks underlying conation and cognition (e.g., language, spatial cognition). Dynamic interactions between such circuits result in a perpetual succession of new equilibrium states, opening the door to considerable interindividual behavioral variability and to neuroplastic phenomena. Indeed, a meta-networking organization underlies the uniquely human propensity to learn complex abilities, and also explains how postlesional reshaping can lead to some degrees of functional compensation in brain-damaged patients. We discuss the major implications of this approach in fundamental neurosciences as well as for clinical developments, especially in neurology, psychiatry, neurorehabilitation, and restorative neurosurgery.

How a crisis mindset activates intuitive decision process: role of inattentional blindness

The current research provides novel evidence on how intuitive decision process is activated under a crisis condition and demonstrates a substantial and robust relationship among crisis mindset, inattentional blindness, and intuitive decision. We activate and measure a crisis mindset instead of directly measuring a crisis situation because a crisis can affect people only if they perceive and interpret it as a crisis. In Experiment 1, we find that a crisis mindset leads to a higher level of inattentional blindness. In Experiment 2, we provide direct evidence that inattentional blindness creates a bridge between a crisis mindset and intuitive decision. In conclusion, we fill the research gap on how crisis links to intuitive decision by demonstrating the key role of inattentional blindness in activating intuitive decision under a crisis condition.

The assessment dimension of regulatory mode mediates the relation between frontoparietal connectivity and risk-taking: Evidence from voxel-base morphometry and functional connectivity analysis

We used voxel-based morphometry and resting-state functional magnetic resonance imaging (rs-fMRI) to investigate whether the regulatory mode orientation of assessment (the tendency of each individual to self-regulate by critically evaluating alternatives) interacts with neural systems underlying risk-taking. Across a sample of 112 participants, propensity for risk-taking (measured using the Wheel of Fortune task) was negatively correlated with assessment orientation, such that a greater tendency to critically evaluate alternatives was associated with a lower tendency for risk-taking. VBM revealed a negative correlation between assessment orientation and right inferior parietal lobe (RIPL) gray matter volume. Resting-state functional connectivity (rs-FC) between this same RIPL region and the left inferior frontal gyrus (LIFG) was positively correlated with assessment orientation in an independent sample of 41 participants. Most importantly, based on the rs-FC results, a mediation analysis indicated that assessment orientation played a completely mediating role in the relation between the functional connectivity of RIPL-LIFG and risk-taking. These results suggest that assessment orientation may affect risk-taking via the RIPL and its connectivity with LIFG. On the whole, the present study yields the insights into how the assessment dimension of regulatory mode affects risk-taking, and provides a novel account of the neural substrate of this relationship.

Are Negative Symptoms Merely the "Real World" Consequences of Deficits in Social Cognition?

Many investigations have demonstrated that negative symptoms and social cognitive deficits in schizophrenia play a large role in determining functional outcomes and ultimately long-term prognosis. Given this, there is increasing interest in understanding the relationship between these two symptom domains, particularly since studies have consistently found moderate to large associations between them. This shared variance raises a key question: to what degree do these two categories of symptoms arise from overlapping or identical changes in brain function? In other words, do some or all negative symptoms represent merely the downstream effects of social cognition deficits on daily functioning? In this commentary, the evidence for and against this possibility, limitations of currently validated empirical measurements of these symptoms, and directions for further investigation of this hypothesis are discussed. Understanding the shared and distinct mechanisms of these disabling deficits will have important implications for the design of novel, personalized treatments for psychotic illness.

Quality of life is related to the functional connectivity of the default mode network at rest

Quality of life is an important issue concerning people all over the world and affecting patients in the mental health field. When considering the potential neural links between quality of life and the brain, a brain network that comes into mind is the default mode network (DMN). Its architecture and function has been investigated in relation to various research fields including social and emotional cognition, meditation and neuropsychiatric disorders as well as happiness. In this cross-sectional study we investigated the relationship between various quality of life domains (physiological, psychological, social and environmental) and the functional connectivity of the default mode network at rest in a sample of 42 healthy working female managers. The results indicate that there is a significant association between the social quality of life domain and the functional connectivity of the default mode network. Post-hoc analysis revealed that high social quality of life scores were associated with right-left lateral parietal hypoconnectivity. By adopting a wide ranging perspective, our study approaches to fundamental research about quality of life but so far only applied on a female subgroup. As far as we know, it is the first to analyze the neuronal correlates of quality of life in the brain and therefore sets an initial step in its investigation.

One cranium, two brains not yet introduced: Distinct but complementary views of the social brain

Social behavior is pervasive across the animal kingdom, and elucidating how the brain enables animals to respond to social contexts is of great interest and profound importance. Our understanding of 'the social brain' has been fractured as it has matured. Two drastically different conceptualizations of the social brain have emerged with relatively little awareness of each other. In this review, we briefly recount the history behind the two dominant definitions of a social brain. The divide that has emerged between these visions can, in part, be attributed to differential attention to cortical or sub-cortical regions in the brain, and differences in methodology, comparative perspectives, and emphasis on functional specificity or generality. We discuss how these factors contribute to a lack of communication between research efforts, and propose ways in which each version of the social brain can benefit from the perspectives, tools, and approaches of the other. Interface between the two characterizations of social brain networks is sure to provide essential insight into what the social brain encompasses.

Two-Person Approaches to Studying Social Interaction in Psychiatry: Uses and Clinical Relevance

Social interaction is ubiquitous in human society. The two-person approach-a new, powerful tool to study information exchange and social behaviors-aims to characterize the behavioral dynamics and neural mechanisms of real-time social interactions. In this review, we discuss the benefits of two-person approaches compared to those for conventional, single-person approaches. We describe measures and paradigms that model social interaction in three dimensions (3-D), including eye-to-eye, body-to-body, and brain-to-brain relationships. We then discuss how these two-person measures and paradigms are used in psychiatric conditions (e.g., autism, mood disorders, schizophrenia, borderline personality disorder, and psychotherapy). Furthermore, the advantages of a two-person approach (e.g., dual brain stimulation, multi-person neurofeedback) in clinical interventions are described. Finally, we discuss the methodological and translational challenges surrounding the application of two-person approaches in psychiatry, as well as prospects for future two-/multi-person studies. We conclude that two-person approaches serve as useful additions to the range of behavioral and neuroscientific methods available to assess social interaction in psychiatric settings, for both diagnostic techniques and complementary interventions.

Differences between individuals with schizophrenia or obsessive-compulsive disorder and healthy controls in social cognition and mindfulness skills: A controlled study

The study of social cognition (SC) has emerged as a key domain of mental health, supporting the notion that poorer performance in SC tasks is linked to psychopathology, although most studies have primarily addressed only schizophrenia (SZ). Some recent studies have also shown deficits of SC in obsessive-compulsive disorder (OCD) patients; however, little is known about how individuals with OCD may differ on SC performance from individuals with SZ. Moreover, initial research in this field suggests that mindfulness skills may be related to SC abilities such as theory of mind (ToM), emotion processing and empathy. Given the potential benefits of mindfulness for treating OCD and SZ, further efforts are needed to understand the association between mindfulness and SC in these populations. The main objective of this study was to compare samples of patients with SZ and OCD to healthy controls (HCs) on several social cognition (SC) domains and mindfulness measures. In total, 30 outpatients diagnosed with SZ, 31 outpatients diagnosed with OCD and 30 healthy controls were assessed in emotion recognition (the Eyes Test), ToM (the Hinting Task), attributional style (the Ambiguous Intentions and Hostility Questionnaire), empathy (the Interpersonal Reactivity Index) and dispositional mindfulness (the MAAS and the FFMQ). Both clinical groups showed poorer performance in emotion recognition and ToM than the HCs. The OCD and SZ patients did not significantly differ in impairment in SC, but the OCD group had higher scores in attributional style (intentionality and anger bias). With regard to mindfulness, the results found lower levels of acting with awareness for the HCs than for either clinical group and higher non-reactivity to inner experience for the HCs than for the individuals with OCD; the results also yielded significant correlations between SC and mindfulness. In conclusion, these findings revealed that SC abilities were impaired in the SZ and OCD groups compared to the HC group, suggesting a similar disrupted pattern in both clinical groups. Aspects of dispositional mindfulness were differentially associated with SC, which may suggest their potential role in novel transdiagnostic interventions.

Mother Schema, Obstetric Dilemma, and the Origin of Behavioral Modernity

What triggered the emergence of uniquely human behaviors (language, religion, music) some 100,000 years ago? A non-circular, speculative theory based on the mother-infant relationship is presented. Infant "cuteness" evokes the infant schema and motivates nurturing; the analogous mother schema (MS) is a multimodal representation of the carer from the fetal/infant perspective, motivating fearless trust. Prenatal MS organizes auditory, proprioceptive, and biochemical stimuli (voice, heartbeat, footsteps, digestion, body movements, biochemicals) that depend on maternal physical/emotional state. In human evolution, bipedalism and encephalization led to earlier births and more fragile infants. Cognitively more advanced infants survived by better communicating with and motivating (manipulating) mothers and carers. The ability to link arbitrary sound patterns to complex meanings improved (proto-language). Later in life, MS and associated emotions were triggered in ritual settings by repetitive sounds and movements (early song, chant, rhythm, dance), subdued light, dull auditory timbre, psychoactive substances, unusual tastes/smells and postures, and/or a feeling of enclosure. Operant conditioning can explain why such actions were repeated. Reflective consciousness emerged as infant-mother dyads playfully explored intentionality (theory of mind, agent detection) and carers predicted and prevented fatal infant accidents (mental time travel). The theory is consistent with cross-cultural commonalities in altered states (out-of-body, possessing, floating, fusing), spiritual beings (large, moving, powerful, emotional, wise, loving), and reports of strong musical experiences and divine encounters. Evidence is circumstantial and cumulative; falsification is problematic.

Loneliness and Adolescents' Neural Processing of Self, Friends, and Teachers: Consequences for the School Self-Concept

The present interdisciplinary study explored whether perceived loneliness is associated with ventromedial prefrontal cortex (vMPFC) activation during self- and social judgments (friends and teachers) in adolescents. Moreover, we examined how vMPFC activity is related to the academic self-concept (ASC). Results of manifest path analysis indicated that high perceived loneliness was related to lower neural response to self-judgments. In turn, high neural response to self-judgments was positively associated with the ASC, whereas there was a trendwise negative association between high neural response to teacher-related judgments and ASC. This study reveals associations between perceived loneliness and neural processing of the self, underlining the idea that feeling isolated from others may hinder self-insight and, by extension, the formation of a stable academic self-concept.

Mentalizing Based on External Features in Borderline Personality Disorder Compared With Healthy Controls: The Role of Attachment Dimensions and Childhood Trauma

Extant research suggests that borderline personality disorder (BPD) is associated with impairments in mentalizing, that is, comprehending behavior in terms of underlying mental states. However, the precise nature of these impairments remains unclear. The literature is mixed concerning mental-izing based on external features of others, and specifically facial emotion recognition (FER) in BPD patients. This study investigated FER differences in 79 BPD patients and 79 matched healthy controls using the Reading the Mind in the Eyes Test (RMET). The authors also investigated attachment dimensions and childhood trauma in relation to mentalizing based on external features. Results showed that BPD patients performed worse on positive and negative emotions. Furthermore, avoidant attachment was negatively related to FER for neutral emotions, particularly in the control group. Trauma was negatively related to FER at trend level, particularly in BPD patients. The implications for this understanding of mentalizing based on external features in BPD are discussed.
