The neuroscience of empathy: progress, pitfalls and promise

Neural signatures underlying the effect of social structure on empathy and altruistic behaviors

Humans inhabit complex social networks, monitoring social structures that encompass both direct and indirect relationships. However, previous research primarily focused on direct relationships, leaving the neural basis of how social structure influences socioemotional processes understudied. This study addressed this gap by investigating the neural pathways underlying the influence of social structure on empathy and altruistic behaviors. During fMRI scanning, participants viewed painful or non-painful stimulation to innocent strangers who shared preferences with targets who had either treated participants fairly or unfairly. Afterwards, participants rated the pain experienced by these innocents and shared money with other innocents. Participants showed reduced empathic and altruistic responses toward innocents resembling unfair (vs. fair) targets, accompanied by heightened activation in regions crucial for emotion regulation and mentalizing, such as the lateral and medial prefrontal cortex. Furthermore, whole-brain and local neural patterns in the anterior insula and premotor cortex robustly discriminated painful (but not non-painful) stimulation of different innocents, suggesting that social structure altered emotional and sensorimotor aspects of empathy. These alterations might be driven by top-down regulation, as indicated by heightened functional connectivity between the lateral prefrontal cortex and sensorimotor areas, as well as between the anterior insula and subgenual anterior cingulate cortex when witnessing the pain of innocents resembling fair (vs. unfair) targets. Together, our work is the first to uncover the neural underpinnings through which human empathy and altruistic behaviors are shaped by social structure beyond direct self-other relationships.

Childhood abuse and neglect are differentially related to perceived discrimination and structural change in empathy-related circuitry

Behavioral studies indicate that adverse childhood experiences (ACE) are associated with altered empathic responding, but the neural mechanisms underlying this relationship remain unclear. Given the significance of empathy in contexts marred by historical conflict and systemic inequality, work on these mechanisms is particularly important in such contexts. The current study extends previous work by (1) examining associations of different dimensions of ACE with volumetric change in empathy-related circuitry, (2) distinguishing between trait and state empathy, and (3) including perceived discrimination as an additional psychosocial stressor. Thirty-nine healthy South African adults from the general population (Mage = 40.6 years) underwent 3 T MRI. FreeSurfer v6.0 was used to extract predefined volumes subserving empathy. Results showed that childhood abuse and perceived discrimination were associated with reduced state empathic concern, whereas childhood neglect was associated with reduced trait cognitive empathy. Childhood abuse was furthermore associated with volumetric increases in frontolimbic (hippocampus, anterior cingulate cortex (ACC)) and neocortical (superior frontal and temporal) regions subserving affective and cognitive empathy, and uniquely mediated the relationship between ACC volume and perceived discrimination. The association of ACE with altered empathic responding may thus be underpinned by specific circuitry reflective of adversity type, with childhood abuse contributing to heightened responsivity to socioemotional cues.

Social neuropsychology of epilepsy in the digital age: A narrative review on challenges and opportunities

BACKGROUND AND OBJECTIVES

Social cognition (e.g., theory of mind and emotion recognition) is frequently impaired in people with epilepsy (PWE) and plays a critical role in social functioning. The impact of the digital revolution on the social neuropsychology of PWE remains underexplored, while clinical neuropsychology has been slow to incorporate technological advancements. This study aims to (a) evaluate the impact of digital communication on social cognition and functioning in PWE, and (b) explore the potential of digital tools to enhance their assessment.

METHODS

Given the limited and fragmented nature of the available research, a non-systematic, exploratory, narrative approach was adopted. Literature relevant to the interplay of digital communication, social cognition, and social functioning in PWE was synthesized to identify key areas for future research.

RESULTS

Digital communication differs from face-to-face interaction at phenomenological and neural levels; however, research on its effects in PWE remains scarce. Traditional social cognition assessments suffer from low ecological validity. Technological innovations, involving second-person paradigms and dynamic multimodal assessments, address these limitations. Digital biomarkers enable high-frequency, longitudinal data collection of intra-individual variability.

CONCLUSION

Digital tools offer the opportunity to improve the assessment of social cognition and functioning in PWE, especially regarding ecological validity, by enabling real-world, interactive, dynamic, and multimodal paradigms. Digital social cognitive proxies (e.g., markers of interactional synchrony) may help capture social cognition and functioning in highly dynamic disease trajectories in PWE more accurately. The interplay between social cognition, social functioning, and digital communication in PWE offers research opportunities into their complex and dynamic relationships.

Social interaction as a unique form of reward - Insights from healthy ageing and frontotemporal dementia

The drive for positive social interactions, or "social rewards", is an important motivator of human behaviour, conferring several adaptive benefits. Social motivation fluctuates across the lifespan, reflecting changes in goals and priorities at different developmental stages. In older adulthood, for instance, priorities tend to shift toward maintaining emotional wellbeing and resources over seeking novel gains. Contemporary theories of social interaction must account for such motivational shifts, addressing the enhancement of social processing in ageing and its decline in dementia. Here, we propose a framework to track the evolution of social motivation across the lifespan, focusing on three mechanisms: (i) social interactions as rewards, (ii) learning from social interactions, and (iii) the effort required for social interactions. We posit that social rewards hold equivalent or increased value later in life, enhancing older adults' social connections. Conversely, social rewards become devalued in neurodegenerative disorders such as frontotemporal dementia (FTD), resulting in social withdrawal. This integrative framework serves as a foundation for understanding adaptive and maladaptive trajectories of social motivation throughout the adult lifespan.

Seeing is Not Thinking: Testing Capabilities of VR to Promote Perspective-Taking

Virtual Reality (VR) technologies offer compelling experiences by allowing users to immerse themselves in simulated environments interacting through avatars. However, despite its ability to evoke emotional responses, and seeing 'through the eyes' of the displayed other, it remains unclear to what extent VR actually fosters perspective-taking (PT) or thinking about others' thoughts and feelings. It might be that the common belief that one can "become someone else" through VR is misleading, and that engaging situations through a different viewpoint does not produce a different cognitive standpoint. To test this, we conducted a 2 (perspective, first-person or third-person) by 2 (perspective-taking task or no task) to examine effects on perspective taking, measured via audio-recordings afforded by the think-aloud protocol. Our data demonstrate that while first-person perspective (1PP) facilitates perceived embodiment, it has no appreciable influence on perspective-taking. Regardless of 1PP or third-person perspective (3PP), perspective-taking was substantially and significantly increased when users were given a specific task prompting them to actively consider a character's perspective. Without such tasks, it seems that participants default to their own viewpoints. These data highlight the need for intentional design in VR experiences to consider content rather than simply viewpoint as key to authentic perspective-taking. To truly harness VR's potential as an "empathy machine," developers must integrate targeted perspective-taking tasks or story prompts, ensuring that cognitive engagement is an active component of the experience.

Reducing racial ingroup biases in empathy and altruistic decision-making by shifting racial identification

Findings of racial ingroup biases in empathy and social behaviors require understanding of relevant psychological and brain mechanisms. Using self-report, behavioral, and neuroimaging measures, we tested the hypothesis that racial identification provides a cognitive basis for racial ingroup biases in empathy and altruistic decision-making. We showed that a mask training procedure using other-race facial disguises altered self-face perception and promoted identification with the other race. Shift in racial identification modulated the medial prefrontal activity, increased electrophysiological responses to pain expressions of other-race faces, enhanced the right premotor/frontal/insular activities in response to perceived painful stimulation to other-race individuals, and decreased own-race favoritism in altruistic decision-making. Furthermore, the medial prefrontal activity related to the shift in racial identification predicted greater neural responses to other-race pain after the training procedure. Our findings highlight the shift of racial identification as a psychological basis for reducing racial ingroup biases in social emotions and behaviors.

Conceptualizing an antiracist framework for neuroscience research in art therapy: a qualitative pilot study

Introduction

Advances in social cognitive neuroscience research have contributed deeper understanding of neural processes relevant to art therapy, and of social, interrelational phenomena including racism and implicit bias. Confoundingly, emerging critical discourse about neuroscience research design highlighted systemic racism, implicit bias, and inequality perpetuated by imaging technologies, lack of diversity, and funding disparities. Emphasis toward antiracist practices within cognitive neuroscience research and various other fields has grown; however, literature on antiracist research practices within art therapy research is scant.

Methods

The purpose of this qualitative pilot research study was to elicit conceptualizations about antiracist research practices from art therapy researchers in response to relevant literature. Purposive sampling was used to recruit four female art therapy researchers from the United States (U.S.) and Europe. Semi-structured interviews were analyzed using grounded theory coding resulting in three main categories, seven themes, and subthemes. Member-checking and reflexive journaling were employed to enhance credibility.

Results

Core categories revealed points of convergence across participants, areas of concern, and requirements outlining antiracist research practices in art therapy. The first core category, shared beliefs and values, had three themes: neuroscience-informed perspective of art therapy; neuroscience research can strengthen art therapy theories; and infusion of antiracism and neuroscience into art therapy begins with education. The second core category, barriers and challenges, had two themes: potential credibility and legitimacy concerns for art therapy; and difficult conversations about disparities in awareness, diversity, and resources. The third core category, requirements and responsibilities for antiracist research, had two themes: due diligence to build accountability and legitimacy; and inclusion of diversity in art therapy research, and subthemes.

Discussion

Preliminary outcomes revealed ideas aligning current antiracist neuroscience research discourse with art therapy experimental research practices. The small group of neuroscience-focused art therapist researchers provided realistic considerations about amplifying discourse within the art therapy profession and infusing antiracist research into neuro-informed art therapy curriculum, and prioritizing diversity throughout experimental research design. An antiracist art therapy research framework with principles including education, intentionality, and diversity was proposed, along with recommendations for further research using the framework and to implement the framework into graduate art therapy education.

Cortical structure in relation to empathy and psychopathy in 800 incarcerated men

Background

Reduced affective empathy is a hallmark of psychopathy, which incurs major interpersonal and societal costs. Advancing our neuroscientific understanding of this reduction and other psychopathic traits is crucial for improving their treatment.

Methods

In 804 incarcerated adult men, we administered the Perspective Taking (IRI-PT) and Empathic Concern (IRI-EC) subscales of the Interpersonal Reactivity Index, Hare Psychopathy Checklist-Revised (PCL-R; two factors), and T1-weighted MRI to quantify cortical thickness (CT) and surface area (SA). We also included the male sample of the Human Connectome Project (HCP; N = 501) to replicate patterns of macroscale structural organization.

Results

Factor 1 (Interpersonal/Affective) uniquely negatively related to IRI-EC, while Factor 2 (Lifestyle/Antisocial) uniquely negatively related to IRI-PT. Cortical structure did not relate to either IRI subscale, although there was effect-size differentiation by microstructural class and/or functional network. CT related to Factor 1 (mostly positively), SA related to both factors (only positively), and both cortical indices demonstrated out-of-sample predictive utility for Factor 1. The high-psychopathy group (N = 178) scored uniquely lower on IRI-EC while having increased SA (but not CT). Regionally, these SA increases localized primarily in the paralimbic class and somatomotor network, with meta-analytic task-based activations corroborating affective-sensory importance. High psychopathy also showed "compressed" global and/or network-level organization of both cortical indices, and this organization in the total sample replicated in HCP. All findings accounted for age, IQ, and/or total intracranial volume.

Conclusions

Psychopathy had negative relationships with affective empathy and positive relationships with paralimbic/somatomotor SA, highlighting the role of affect and sensation.

Early Life Adversity and Empathy: A Scoping Review of Past Research and Recommendations for Future Directions

Early life adversity (ELA) describes stressful experiences that may increase risk for psychopathology and impact emotion regulation and executive functioning systems. The influence of ELA on the development of empathy-the ability to understand and resonate with others' thoughts and emotions-remains understudied, despite the fact that empathy development relies on cognitive and emotional abilities often affected by ELA. This scoping review summarized 43 empirical articles on ELA and empathy to clarify the muddled literature and address limitations to inform future research. Across various operationalizations of ELA and empathy, 15 articles suggested that ELA was associated with increased empathy, 19 that ELA was associated with decreased empathy, and 12 pointed to a null association. ELA and empathy showed differing associations across developmental periods, with ELA being more related to higher affective empathy and lower cognitive empathy in youth and higher personal distress in adulthood. Categorization by type of adversity revealed a lack of studies on deprivation and environmental adversity, while examination of empathy operationalization revealed a need for the assessment of empathy components among youth and more task-based measures of empathy. Recommendations for future research include the need to (a) clarify operationalizations of ELA, (b) explore empathy components and naturalistic measures, and (c) focus on outcomes in adolescence. Continued efforts to understand the connection between ELA and empathy will provide valuable insight into the impact of adversity on socioemotional development and guide psychosocial interventions for individuals at risk for maladaptive outcomes following adverse childhood experiences.

Seeing your child in pain: Parent empathy in the context of their child's chronic pain

Observing your child in pain is inherently distressing. In the context of chronic pain, caregiver responses can powerfully impact child pain-related functioning. The Parent Empathy in the Context of Pain model postulates that parent empathic distress may hinder adaptive responses to child pain, thus playing a key role in the link between parent responses and child functioning. Here, we examined how parent empathy is related to parent and child pain-related constructs within the Parent Empathy in the Context of Pain model, using an adapted Empathy for Pain Scale (EPS) for use in parents (P-EPS). Data were collected from 190 parents of youth with chronic pain (170 mothers; children aged 8-18y) and their children. Structural equation modeling (SEM) showed support for the theoretical model. Parent pain-related beliefs were associated with behavioral responses via affective responses of empathy for pain (affective distress) and emotion regulation (emotional suppression), which in turn were associated with child pain-related functioning. Moreover, higher levels of parent empathic distress to observing their child's pain was significantly associated with more general empathic distress, poorer perspective taking and more maladaptive emotion regulation strategy use (emotional suppression). Our findings underscore the involvement of parent affective responses in driving parent maladaptive behavioral responses to their child's pain and emphasize the role of affective empathic distress as well as its regulation. In addition to providing information on its assessment, this empirical investigation provides novel insights into the construct of empathy in this context. PERSPECTIVE: This article presents initial data supporting the Parent Empathy in the Context of Pain model. Findings show involvement of parent affective responses in driving parent maladaptive behavioral responses to their child's chronic pain and emphasize the role of affective empathic distress as well as its regulation.

Humanizing Clients With Internalized Neoliberal Ideology Using Contextual Therapy

The well-being of individuals in the United States is steadily declining, with a concurrent rise in harmful behaviors. Contextual Therapy posits that well-being is grounded in equitable, trust-based relationships-a principle known as relational ethics. However, the dominant ideology of neoliberalism may challenge these connections by promoting individualism and self-interest. Research suggests that neoliberal influences can diminish well-being, prompting individuals to prioritize personal gain over fostering humane connections with others. Contextual Therapy provides therapists with a pathway to address these influences, supporting clients in building healthier, more humanizing relationships. This article seeks to inform therapists of the potential impact of neoliberal values on clients' lives, demonstrating how Contextual Therapy can mitigate these effects and enhance relational ethics. We begin with an overview of neoliberalism and Contextual Therapy, followed by two case examples that illustrate presenting issues potentially influenced by neoliberal factors. Finally, we introduce a framework that mental health practitioners can incorporate into treatment, utilizing Contextual Therapy to address internalized neoliberalism. By cultivating empathy and reinforcing supportive connections, we propose that Contextual Therapy can contribute to improved well-being and a reduction in harmful behaviors.

Interpersonal brain synchronization in social pain contexts: an fNIRS-based exploration of empathy

Social pain is a common occurrence in interpersonal interactions, yet limited research has explored the neural mechanisms underlying both social pain and social pain empathy. Existing studies often focus on the neural processes of individuals experiencing pain, referred to as "subjects," or those empathizing with them, known as "observers." This study examines the neural mechanisms involved in the process of social pain empathy from the perspective of interpersonal brain synchronization (IBS). To do so, we employed functional near-infrared spectroscopy to simultaneously scan the brains of both subjects and observers in social pain scenarios created using the Cyberball paradigm. The study's findings indicate that in social pain contexts, the IBS among dyads composed of subjects and observers was significantly enhanced in the dorsolateral prefrontal cortex compared to nonsocial pain contexts. This brain region is associated with emotion regulation. Furthermore, we found that this enhancement depended on the observers' levels of rejection sensitivity. This study provides the inaugural exploration into the neural mechanisms underlying social pain empathy through the lens of IBS.

Scarcity mindset facilitates empathy for social pain and prosocial intention: behavioral and neural evidences

Empathy for social pain encompasses both affective and cognitive responses to others' emotional reactions following negative social encounters, facilitating an understanding of their suffering and promoting prosocial behaviors. This study examined how a scarcity mindset affects empathy for social pain and prosocial intentions at behavioral and neural levels. Sixty participants were randomly assigned to either the scarcity or abundance mindset group. They viewed images of social exclusion or neutral scenarios and subsequently rated the perceived unpleasantness of the target person and their willingness to provide comfort during a stage-game paradigm. The results showed that participants in the scarcity mindset group demonstrated greater differentiation in their ratings of unpleasantness and willingness to comfort when exposed to social exclusion images compared to neutral ones, relative to the abundance mindset group. Electrophysiological data revealed that social exclusion images elicited larger late positive potential (LPP) amplitudes in the scarcity mindset group, but not in the abundance mindset group. Additionally, within the scarcity mindset group, affective empathy trait scores moderated the relationship between LPP amplitudes and willingness to comfort ratings. These findings highlight the amplifying effects of a scarcity mindset on empathy for social pain and prosocial intentions, and emphasize the role of affective empathy traits in this dynamic process.

Can guilt enhance sensitivity to other's suffering? An EEG investigation into moral emotions and pain empathy

As a unique form of empathy, pain empathy often has a close relationship with society and morality. Research has revealed that moral emotions can influence pain empathy. The underlying physiological mechanism still needs to be further examined to understand how moral emotions affect pain empathy. This study employs EEG and Machine Learning techniques, using a painful image induction paradigm to explore the impact of moral emotion (guilt)-on pain empathy and its neural mechanisms. Participants without pain sensation were instructed to observe and evaluate pictures of an anonymous hand in painful or non-painful pictures under feelings of guilt or neutral emotion. Results found slower reaction times and higher pain ratings for painful pictures. Furthermore, guilt led to higher pain ratings. Under conditions of painful pictures, guilt-induced greater P3(350-450ms) amplitudes and higher α oscillations and enhanced the functional connectivity between the prefrontal cortex, the central frontal region, and the parieto-occipital lobe. K-nearest neighbor can effectively classify high and low-pain empathy under guilt emotion. The result showed that guilt promotes the brain's processing of painful picture, causing individuals to pay high attention and engage in deep cognitive processing. This study provides insights into enhancing empathy and fostering interpersonal relationships.

Intellectual Humility Predicts Empathic Accuracy and Empathic Resilience

Three preregistered studies (N = 533) investigated the relationship between intellectual humility (IH) and cognitive and emotional empathy. Study 1 (n = 212) revealed a positive association between IH and empathic accuracy (EA), especially toward the outgroup. Study 2 (n = 112) replicated the significant association between IH and EA. Study 3 (n = 209) employed a manipulation to enhance IH to demonstrate causality. We found evidence for an indirect effect, wherein the manipulation increased state IH, which was associated with greater EA. A mini meta-analysis revealed that, on average, individuals with higher levels of IH exhibit increased EA, showing a greater understanding of others' emotional states. Moreover, IH predicts empathic resilience-buffering against personal distress while maintaining or increasing empathic concern for others. These findings highlight the positive influence of IH on empathy, emphasizing its potential for fostering deeper connections and better understanding in social interactions.

Relational neuroscience: Insights from hyperscanning research

Humans are highly social, typically without this ability requiring noticeable efforts. Yet, such social fluency poses challenges both for the human brain to compute and for scientists to study. Over the last few decades, neuroscientific research of human sociality has witnessed a shift in focus from single-brain analysis to complex dynamics occurring across several brains, posing questions about what these dynamics mean and how they relate to multifaceted behavioural models. We propose the term 'Relational Neuroscience' to collate the interdisciplinary research field devoted to modelling the inter-brain dynamics subserving human connections, spanning from real-time joint experiences to long-term social bonds. Hyperscanning, i.e., simultaneously measuring brain activity from multiple individuals, has proven to be a highly promising technique to investigate inter-brain dynamics. Here, we discuss how hyperscanning can help investigate questions within the field of Relational Neuroscience, considering a variety of subfields, including cooperative interactions in dyads and groups, empathy, attachment and bonding, and developmental neuroscience. While presenting Relational Neuroscience in the light of hyperscanning, our discussion also takes into account behaviour, physiology and endocrinology to properly interpret inter-brain dynamics within social contexts. We consider the strengths but also the limitations and caveats of hyperscanning to answer questions about interacting people. The aim is to provide an integrative framework for future work to build better theories across a variety of contexts and research subfields to model human sociality.

Prenatal Methamphetamine Exposure Impairs Helping Behaviour in Male Offspring: The Possible Role of miR-223 and NLRP3 Inflammasomes in the Amygdala

The increasing prevalence of methamphetamine abuse among women, particularly pregnant females, is a global concern. Methamphetamine can readily cross anatomical barriers like the blood-placenta barrier and cause detrimental impacts on the growing fetus. The current research evaluated the effects of prenatal methamphetamine exposure on helping behaviour and neuroinflammatory cascade in the amygdala of male offspring. On the tenth day of pregnancy, female rats received either saline or methamphetamine (5 mg/kg) until delivery. Once the offspring reached 21 days of age, the male ones were sep arated from their mothers and housed with normal male rats. An empathy-like behaviour test, which measured helping behaviour towards the cage mate, was conducted. The expression levels of miR-223-3p, NLRP3, Caspase 1, and gasdermin D (GSDMD) were evaluated in the amygdala of male offspring. Moreover, interleukin-1β (IL-1β) protein level was measured. Findings of this study revealed that male offspring exposed to methamphetamine during pregnancy had impaired helping behaviour. At the molecular level, prenatal methamphetamine exposure decreased miR-223-3p and increased inflammasome signaling by raising the levels of NLRP3, caspase-1, and GSDMD along with IL-1β levels. These findings indicate that prenatal methamphetamine exposure impairs emotional behaviour and activates inflammasome pathway in the amygdala.

The Dark Side of Empathy: The Role of Excessive Affective Empathy in Mental Health Disorders

Empathy, which is typically regarded as a positive attribute, is now being critically evaluated for its potential negative implications for mental health. A growing body of research indicates that excessive empathy, particularly a high level of affective empathy, can lead to overwhelming emotional states, thereby increasing susceptibility to psychological distress and psychiatric disorders. In this review, we aim to explore the negative effects of empathy on mental health. We review both human and animal studies concerning the relationship between empathy and psychological disorders, revealing that while empathy enhances social interactions and emotional understanding, it may also heighten empathic distress and potentially contribute to the development of pain, internalizing disorders, depression, anxiety, emotional overinvolvement, burnout, vicarious trauma, and posttraumatic stress disorder. This review contributes to the broader discourse on empathy by delineating its dual impacts, integrating insights from neurobiology, psychology, and behavioral studies. This review may enhance our understanding of empathy's complex role in mental health, offering a nuanced perspective that acknowledges both its beneficial and detrimental impacts.

Restless nights, cold hearts: Poor sleep causally blunts empathy

Poor sleep is pervasive in modern society. Poor sleep is associated with major physical and mental health consequences, as well as with impaired cognitive function. Less is known about the relationship between sleep and emotional and interpersonal behavior. In this work, we investigate whether poor sleep impairs empathy, an important building block of human interaction and prosocial behavior. We aimed to capture the effects of poor sleep on the various aspects of empathy: trait and state, affect and cognition. Study 1 (n = 155) assessed daily habitual sleep over several days, and global sleep quality in the past month. Participants who reported worse sleep quality exhibited lower empathic caring and perspective-taking traits. Study 2 (n = 347) induced a one-night disruption of sleep continuity to test a causal relationship between sleep and empathy. Participants in the sleep disrupted condition had to briefly wake up five times over the night, whereas the sleep-rested controls slept normally. In the next morning, participants' empathy and prosocial intentions were assessed. Participants in the sleep disruption condition exhibited lower empathic sensitivity and less prosocial decision-making than sleep-rested controls. The main contribution of this work is in providing a robust demonstration of the multi-faceted detrimental effects of poor sleep on trait and state empathy. Our findings demonstrate that poor sleep causally impairs empathic response to the suffering of others. These findings highlight the need for greater public attention to adequate sleep, which may impact empathy on a societal level.

Temporal dynamics of implicit moral evaluation: From empathy for pain to mentalizing processes

To understand how we evaluate harm to others, it is crucial to consider the offender's intent and the victim's suffering. Previous research investigating event-related potentials (ERPs) during moral evaluation has been limited by small sample sizes and a priori selection of electrodes and time windows that may bias the results. To overcome these limitations, we examined ERPs in 66 healthy human adults using a data-driven analytic approach involving cluster-based permutation tests. Participants performed an implicit moral evaluation task requiring to observe scenarios depicting intentional harm (IHS), accidental harm (AHS), and neutral actions (NAS) while judging whether each scenario was set indoors or outdoors. Our results revealed two distinct clusters, peaking at ∼170 and ∼250 ms, showing differences between harm scenarios (IHS and AHS) and NAS, suggesting rapid processing of the victim's physical outcome. The difference between IHS and AHS scenarios emerged later, at ∼400 ms, potentially reflecting subsequent evaluation of the agent's intentions. Source analysis showed that brain regions associated with empathy for pain were associated with the earlier peaks at ∼170 and ∼250 ms, while the modulation of the activity of the mentalizing network was presented at ∼250 and ∼400 ms. These findings advance our understanding of the neural mechanisms underlying implicit moral evaluation. Notably, they provide electrocortical new insights for models of implicit moral evaluation, suggesting an early neural response linked to empathy for pain, with subsequent integration of empathy response with mentalizing processes, followed by later cognitive evaluations, likely reflecting the assessment of the agent's moral responsibility.

Early affective empathy, emotion contagion, and empathic concern in borderline personality disorder: A systematic review and meta-analysis

BACKGROUND

Individuals with Borderline Personality Disorder (BPD) are theorized to experience lower cognitive empathy but heightened affective empathy. Despite meta-analyses addressing cognitive empathy, affective empathy remains unexplored. This pre-registered systematic review and meta-analysis investigated affective empathy in individuals with BPD or high BPD traits relative to healthy comparisons, using a multidimensional approach including, early affective empathy, emotion contagion, and empathic concern.

METHODS

Systematic search of SCOPUS, PubMed, Medline COMPLETE, and PsycINFO (June 27, 2022, May 14, 2023, and July 1, 2024) was completed. Included studies compared affective empathy in those with BPD/high BPD traits with healthy comparisons, utilized experimental or self-report designs, and were peer-reviewed or PhD theses. Risk of bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

Among 22 eligible studies identified, results revealed individuals with BPD/high BPD traits showed significantly higher emotion contagion (Npooled = 1797, g = -1.10, 95 % CI [-1.57, -0.62]). No significant differences were found in empathic concern (Npooled = 1545, g = 0.06, 95 % CI [-0.10, 0.22]), or early affective empathy for anger (Npooled = 245, g = 0.28, 95 % CI [-0.0.53, 1.09]) and happiness, (Npooled = 189, g = 0.34, 95 % CI [-0.1.50, 2.18]).

LIMITATIONS

Few included studies for early affective empathy, methodological shortcomings in the broader literature and study heterogeneity suggest caution when interpreting these effects, emphasizing the need for targeted research.

CONCLUSIONS

While individuals with BPD/high BPD traits are more likely to subjectively experience others' distress through emotion contagion, no differences were found in early affective empathy or ability to direct sympathy and concern towards others.

Psychologists should study basic social cognition processes within the context of sexual interactions

Research in psychology has long underscored the significance of contextual influence on social cognition processes and behavior. However, the exploration of sexual interactions as a unique context affecting these processes has largely been neglected by previous research, despite their prominent role in our daily lives and potentially consequential outcomes. We outline the relevance of various basic social cognition processes to sexual interactions and propose a line of research integrating theoretical insights and methodologies from social cognition research with those from sex and relationship research. We elaborate on theoretical and applied contributions to both fields.

Distinct Patterns of Socioemotional Dysfunction Relate to Aggressive Versus Nonaggressive Rule-breaking Antisocial Behaviors in Behavioral Variant Frontotemporal Dementia

BACKGROUND

Antisocial behaviors occur in up to 91% of individuals with behavioral variant frontotemporal dementia (bvFTD). Prior work has shown that antisocial behaviors can be differentiated into aggressive and nonaggressive rule-breaking behavioral subtypes. Socioemotional dysfunction is common in bvFTD and unique compared to other types of dementia.

OBJECTIVE

To determine whether socioemotional dysfunction relates to general antisocial behaviors in individuals with bvFTD, or whether different types of socioemotional dysfunction relate to aggressive versus rule-breaking behaviors.

METHODS

Informants for 28 participants with bvFTD and 21 participants with Alzheimer disease (AD) completed the Social Behavior Questionnaire (SBQ) and the Interpersonal Reactivity Index (IRI). The SBQ measures the presence and severity of 26 antisocial behaviors, including subscales for aggressive behaviors (SBQ-AGG) and nonaggressive rule-breaking behaviors (SBQ-RB). The IRI measures cognitive and emotional empathy capabilities, including subscales for Empathic Concern (IRI-EC) and Perspective-taking (IRI-PT).

RESULTS

As expected, participants with bvFTD had higher scores on the SBQ in total than participants with AD, as well as on the SBQ-AGG and SBQ-RB separately. Participants with bvFTD had lower scores on the IRI-EC and IRI-PT than participants with AD (P < 0.0001 for all measures). Lower scores on the IRI-PT correlated with higher scores on the SBQ-AGG-but not with higher scores on the SBQ-RB-across the combined group of participants (P = 0.007), and within participants in the bvFTD group (P = 0.01) specifically, after controlling for covariates of age, sex, dementia severity, and IRI-EC scores. Lower scores on the IRI-EC correlated with higher scores on the SBQ-AGG-but not with higher scores on the SBQ-RB-across the combined group of participants (P = 0.02) after controlling for covariates of age, sex, dementia severity, and IRI-PT scores.

CONCLUSION

Our results suggest that socioemotional dysfunction relates to antisocial behaviors in individuals with bvFTD, but that the mechanisms leading to aggressive and rule-breaking behaviors are differentiable, providing meaningful implications for distinct approaches to treatment and prevention.

New Vistas for the Relationship between Empathy and Political Ideology

The study of ideological asymmetries in empathy has consistently yielded inconclusive findings. Yet, until recently these inconsistencies relied exclusively on self-reports, which are known to be prone to biases and inaccuracies when evaluating empathy levels. Very recently, we reported ideological asymmetries in cognitive-affective empathy while relying on neuroimaging for the first time to address this question. In the present investigation which sampled a large cohort of human individuals from two distant countries and neuroimaging sites, we re-examine this question, but this time from the perspective of empathy to physical pain. The results are unambiguous at the neural and behavioral levels and showcase no asymmetry. This finding raises a novel premise: the question of whether empathy is ideologically asymmetrical depends on the targeted component of empathy (e.g., physical pain vs cognitive-affective) and requires explicit but also unobtrusive techniques for the measure of empathy. Moreover, the findings shed new light on another line of research investigating ideological (a)symmetries in physiological responses to vicarious pain, disgust, and threat.

Nearsighted empathy: exploring the effect of empathy on distance perception, with eye movements as modulators

Empathy, a cornerstone of social interaction, involves shared representation, eliciting vicarious emotions. However, its influence on shared perceptual representations, particularly in foundational domains such as distance perception, remains unexplored. In this study, we introduce a novel adaptation of the empathy for pain task to investigate empathy's influence on distance perception. We also examine how two personality traits, trait empathy and alexithymia, modulate this relationship. Utilizing eye-tracking technology, we examine how attention allocation to different facial and bodily features affects empathy's impact on distance perception. Our findings indicate that empathy biases individuals to perceive targets as closer, with trait empathy reinforcing this effect and alexithymia attenuating it. Furthermore, we demonstrate that heightened attention to eyes and face correlates with perceiving targets as closer, while attention to hand shows the opposite trend. These results underscore the broader influence of empathy beyond shared emotions, revealing its capacity to alter perceptual processes. By elucidating the interplay between personality traits and visual inputs in shaping these alterations, our study offers valuable insights for future research exploring the role of shared representation in empathy across various perceptual domains.

Effects of classical psychedelics on implicit and explicit emotional empathy and cognitive empathy: a meta-analysis of MET task

This meta-analysis investigates the effect of classic psychedelic drugs on empathy and focuses on cognitive and emotional empathy measured using the Multifaceted Empathy Test (MET). Empathy entails the ability to understand and share the feelings of another and is a significant component of social interaction. Several studies have examined the effects of psychedelic drugs such as LSD, psilocybin and ayahuasca on empathy, yet their overall effect has not been studied so far. In this meta-analysis, we reviewed data from studies up to November 2023 with the aim of examining the effects of various psychedelic drugs on empathic abilities broadly. Our findings suggest that classical psychedelics significantly enhance explicit and implicit emotional empathy without affecting measures of cognitive empathy. The results emphasize the need to continue testing the therapeutic potential of classic psychedelic drugs.

Placebos in Healthcare: A Behavioral Study on How Treatment Responsiveness Affects Therapy Decisions in a Simulated Patient-Physician Interaction

BACKGROUND AND PURPOSE

Treatment choice during clinical practice is crucial to best help each patient. One of the physicians' main goals is choosing a personalized effective treatment, but it also represents a challenging issue. Here, we explored different treatment choices in a simulated patient-physician interaction.

MATERIALS AND METHODS

Medical students (n = 48) and young Practicing Physicians (n = 20) were recruited to behave as "physicians" while fellow researchers acted as "patients". Participants were divided equally into a Belief Group, which received positive information about placebo efficacy, and a Non-Belief Group, which received negative information. Empathy traits and psychological variables were measured in both groups. During the task, participants were asked to choose between an active (TENS treatment) or a placebo treatment, to reduce patients' pain. Patients never underwent the painful stimulation but acted as if they had, simulating high or low pain responses to the placebo treatment (placebo-responders/placebo non-responders) and low pain to the TENS treatment.

RESULTS

Behavioral results showed that the Belief Group gave significantly more placebo treatments when faced with a patient that simulated placebo responsiveness, while the Non-Belief group showed a mirrorlike behavior, administrating more believed TENS treatments when faced with a placebo non-responder. No differences were found between Medical Students and Practicing Physicians.

CONCLUSIONS

This study constitutes a frame of reference for medical treatment decisions, indicating that physicians' treatment choices are influenced by patients' responsiveness to the treatments, as well as by their prior beliefs and empathy traits.

Cognitive control: exploring the causal role of the rTPJ in empathy for pain mediated by contextual information

Empathy determines our emotional and social lives. Research has recognized the role of the right temporoparietal junction (rTPJ) in social cognition; however, there is less direct causal evidence for its involvement in empathic responses to pain, which is typically attributed to simulation mechanisms. Given the rTPJ's role in processing false beliefs and contextual information during social scenarios, we hypothesized that empathic responses to another person's pain depend on the rTPJ if participants are given information about people's intentions, engaging mentalizing mechanisms alongside simulative ones. Participants viewed videos of an actress freely showing or suppressing pain caused by an electric shock while receiving 6 Hz repetitive transcranial magnetic stimulation (rTMS) over the rTPJ or sham vertex stimulation. Active rTMS had no significant effect on participants' ratings depending on the pain expression, although participants rated the actress's pain as lower during rTPJ perturbation. In contrast, rTMS accelerated response times for providing ratings during pain suppression. We also found that participants perceived the actress's pain as more intense when they knew she would suppress it rather than show it. These results suggest an involvement of the rTPJ in attributing pain to others and provide new insights into people's behavior in judging others' pain when it is concealed.

Impairment of affective and cognitive empathy in high functioning autism is mediated by alterations in emotional reactivity

Empathy impairments are considered a key aspect of autism-spectrum disorders (ASD). Previous research consistently shows reduced cognitive empathy, but findings on affective empathy vary, possibly due to experimental design variations (e.g., stimulus modality, social distance) and individual psychological factors (e.g., perceptual abilities, emotional reactivity). This study aims to clarify deficits in affective and cognitive empathy in ASD by addressing these contributing factors. Empathy was examined in 34 autistic individuals and 33 typically developed controls (TDCs) through the Textual Empathy Test (TET). The TET was developed to assess emotional responses when imagining oneself (emotional reactivity) as compared to a target person (friend, stranger) in emotional situations presented via short verbal descriptions. Participants rated emotional states of the target person (cognitive empathy) as well as their own emotional responses when imagining the target person in that situation (affective empathy). Ratings were interpreted relative to normative mean values through standardized regression coefficients. Results showed that high-functioning autism was associated with lower cognitive and affective empathy irrespective of social distance as well as with decreased emotional reactivity compared to controls. Moreover, emotional reactivity mediated the impact of ASD on both empathic components. In summary, altered emotional reactivity may underlie impaired empathy in autistic individuals.

Partisans process policy-based and identity-based messages using dissociable neural systems

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

How collaborative, interpersonal, and disaster-responsive tendencies work together in non-face-to-face environments: lessons from prolonged pandemic experiences

This study investigates the dynamics of collaborative characteristics, interpersonal reactivity, and disaster situation responses in non-face-to-face settings, a response mechanism increasingly relevant in the wake of prolonged pandemics. By examining a group of 123 university students engaged in a seven-week non-face-to-face collaborative project, the research identifies relational patterns between collaborative traits such as regulation and efficacy, interpersonal empathy, and responses to disaster situations. The research methodology employs a sophisticated analytical framework comprising factor and canonical correlation analyses to identify how empathy and collaborative efficacy significantly related with disaster response in online collaborations. The mediation and moderation models analyzed confirm mutual mediation effects of collaborative regulation and interpersonal reactivity on situational empathy without significant moderation effects. This suggests there were direct causal relationships of collaborative regulation, collaborative efficacy, interpersonal reactivity on situational empathy. The findings underscore the pivotal role of empathy in collaboration during disasters offering a nuanced understanding of the social and psychological underpinnings that enable collective responses to crises in environments lacking physical interaction and illuminating the critical role of collaborative and interpersonal skills in such settings.

Empathy-related abnormalities among women with premenstrual dysphoric disorder: clinical and functional magnetic resonance imaging study

BACKGROUND

Empathy refers to the cognitive and emotional reactions of an individual to the experiences of another. Women with premenstrual dysphoric disorder (PMDD) report severe social difficulties during the luteal phase of their menstrual cycle.

AIMS

This clinical and functional magnetic resonance imaging study aimed to explore affective and cognitive empathy in women with PMDD, during the highly symptomatic luteal phase.

METHOD

Overall, 32 women with PMDD and 20 healthy controls participated in the study. The neuroimaging data were collected using a highly empathy-engaging movie. First, we characterised the synchrony of neural responses within PMDD and healthy groups, using the inter-individual correlation approach. Next, using network cohesion analysis, we compared connectivity within and between brain networks associated with affective and cognitive empathy between groups, and assessed the association of these network patterns with empathic measures.

RESULTS

A consistent, although complex, picture of empathy abnormalities was found. Patients with PMDD showed decreased neural synchrony in parietal and frontal key nodes of cognitive empathy processing (theory-of-mind network), but higher neural synchrony in the anterior insula and anterior cingulate cortex, a part of the salience network, implicated in affective empathy. Positive correlations between cognitive perspective-taking scores and neural synchrony were found within the theory-of-mind network. Interestingly, during highly emotional moments, the PMDD group showed increased functional connectivity within this network.

CONCLUSIONS

Similar to major depression, individuals with PMDD show enhanced affective empathy and reduced cognitive empathy. These findings echo clinical observations reported when women with PMDD have a dysregulated emotional response to negative stimuli.

Emotional engagement with close friends in adolescence predicts neural correlates of empathy in adulthood

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, N = 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 reduced 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.

Rorschach Human Movement and Psychotherapy: Relationship with the Therapist's Emotional Responses

The emotional responses of psychotherapists to their patients, known as countertransference, can yield valuable insights into the patient's psychological functioning. Albeit from a different perspective, the Rorschach test also provides information about the patient's psychological processes. In particular, the Rorschach human movement response (M) has been shown to be a useful measure of higher-level psychological functioning. In an attempt to bridge these two largely different perspectives, the aim of this study was to explore the association between M responses in the Rorschach protocols of psychotherapy patients and emotional responses exhibited by their therapists. To this end, a convenience sample of 149 outpatients were administered the Rorschach according to the Comprehensive System, and their therapists completed the Therapist Response Questionnaire. Through a series of regression models, controlling for response style, response complexity, and degree of psychopathology, M demonstrated a significant association with the therapists' emotional responses. A lower number of M responses was associated with the therapists' feelings of disengagement, and a higher number of M responses was associated with the therapists' feelings of being more involved with the patient. Taken together, these results suggest a potential relationship between the number of M responses the respondent gives in the Rorschach and the subsequent development of the therapeutic alliance between the respondent and their therapist.

The anatomical structure of sex differences in trust propensity: A voxel-based morphometry study

Trust is a key component of human relationships. Sex differences in trust behavior have been elucidated by parental investment theory and social role theory, attributing men's higher trust propensity to their increased engagement in physically and socially risky activities aimed at securing additional resources. Although sex differences in trust behavior exist and the neuropsychological signatures of trust are known, the underlying anatomical structure of sex differences is still unexplored. Our study aimed to investigate the anatomical structure of sex differences in trust behavior toward strangers (i.e., trust propensity, TP) by employing voxel-based morphometry (VBM) in a sample of healthy young adults. We collected behavioral data for TP as measured with participants in the role of trustors completing the one-shot trust game (TG) with anonymous partners as trustees. We conducted primary region of interest (ROI) and exploratory whole-brain (WB) VBM analyses of high-resolution structural images to test for the association between TP and regional gray matter volume (GMV) associated with sex differences. Confirming previous studies, our behavioral results demonstrated that men trusted more than women during the one-shot TG. Our WB analysis showed a greater GMV related to TP in men than women in the precuneus (PreC), whereas our ROI analysis in regions of the default-mode network (dorsomedial prefrontal cortex [dmPFC], PreC, superior temporal gyrus) to simulate the partner's trustworthiness, central-executive network (ventrolateral PFC) to implement a calculus-based trust strategy, and action-perception network (precentral gyrus) to performance cost-benefit calculations, as proposed by a neuropsychoeconomic model of trust. Our findings advance the neuropsychological understanding of sex differences in TP, which has implications for interpersonal partnerships, financial transactions, and societal engagements.

Considering the Role of Human Empathy in AI-Driven Therapy

Recent breakthroughs in artificial intelligence (AI) language models have elevated the vision of using conversational AI support for mental health, with a growing body of literature indicating varying degrees of efficacy. In this paper, we ask when, in therapy, it will be easier to replace humans and, conversely, in what instances, human connection will still be more valued. We suggest that empathy lies at the heart of the answer to this question. First, we define different aspects of empathy and outline the potential empathic capabilities of humans versus AI. Next, we consider what determines when these aspects are needed most in therapy, both from the perspective of therapeutic methodology and from the perspective of patient objectives. Ultimately, our goal is to prompt further investigation and dialogue, urging both practitioners and scholars engaged in AI-mediated therapy to keep these questions and considerations in mind when investigating AI implementation in mental health.

Assigning a social status from face adornments: an fMRI study

For at least 150,000 years, the human body has been culturally modified by the wearing of personal ornaments and probably by painting with red pigment. The present study used functional magnetic resonance imaging to explore the brain networks involved in attributing social status from face decorations. Results showed the fusiform gyrus, orbitofrontal cortex, and salience network were involved in social encoding, categorization, and evaluation. The hippocampus and parahippocampus were activated due to the memory and associative skills required for the task, while the inferior frontal gyrus likely interpreted face ornaments as symbols. Resting-state functional connectivity analysis clarified the interaction between these regions. The study highlights the importance of these neural interactions in the symbolic interpretation of social markers on the human face, which were likely active in early Homo species and intensified with Homo sapiens populations as more complex technologies were developed to culturalize the human face.

Aberrant cognitive empathy in individuals with elevated social anxiety and regulation with emotional working memory training

Social anxiety may disrupt the empathic process, and well-regulated empathy is critical for navigating the social world. Two studies aimed to further understand empathy in the context of social anxiety. Study 1 compared individuals with elevated or normative social anxiety on a measure assessing cognitive and affective empathy for positive and negative emotions conveyed by other people ("targets"), completed under social threat. Relative to individuals with normative social anxiety, individuals with elevated social anxiety had greater cognitive empathy and no differences in affective empathy, regardless of emotion type. As greater cognitive empathy can be maladaptive, Study 2 tested whether this could be down-regulated. Individuals with elevated social anxiety underwent emotional working memory training (eWMT) for negative emotional information, or control training (CT). Effects on an empathy measure completed under social threat were assessed. Cognitive empathy for negative emotions decreased following eWMT but not CT, and this was only evident for those with higher pre-training working memory capacity. Cognitive empathy for positive emotions and affective empathy were not affected. Overall, social anxiety is associated with aberrant elevated cognitive empathy for negative and positive emotions, and the deviation in cognitive empathy for negative emotions can be regulated with eWMT for certain individuals.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12618001196235..

Individual differences of white matter characteristic along the anterior insula-based fiber tract circuit for pain empathy in healthy women and women with primary dysmenorrhea

Pain empathy, defined as the ability of one person to understand another person's pain, shows large individual variations. The anterior insula is the core region of the pain empathy network. However, the relationship between white matter (WM) properties of the fiber tracts connecting the anterior insula with other cortical regions and an individual's ability to modulate pain empathy remains largely unclear. In this study, we outline an automatic seed-based fiber streamline (sFS) analysis method and multivariate pattern analysis (MVPA) to predict the levels of pain empathy in healthy women and women with primary dysmenorrhoea (PDM). Using the sFS method, the anterior insula-based fiber tract network was divided into five fiber cluster groups. In healthy women, interindividual differences in pain empathy were predicted only by the WM properties of the five fiber cluster groups, suggesting that interindividual differences in pain empathy may rely on the connectivity of the anterior insula-based fiber tract network. In women with PDM, pain empathy could be predicted by a single cluster group. The mean WM properties along the anterior insular-rostroventral area of the inferior parietal lobule further mediated the effect of pain on empathy in patients with PDM. Our results suggest that chronic periodic pain may lead to maladaptive plastic changes, which could further impair empathy by making women with PDM feel more pain when they see other people experiencing pain. Our study also addresses an important gap in the analysis of the microstructural characteristics of seed-based fiber tract network.

The dark side of personality functioning: associations between antisocial cognitions, personality functioning (AMPD), empathy and mentalisation

Introduction

With the introduction of the new psychiatric diagnostic manuals, personality functioning has gained new prominence. Several studies have reported consistent findings that individual showing high levels of antisocial features are associated with alterations in interpersonal functioning domains such as empathy and mentalisation. The focus of the current study (N = 198) is to examine antisocial cognitions, as measured by the Scrambled Sentences Task (SST), and to what extent this approach can help to better understand the relationship between antisocial traits and personality functioning/empathy.

Method

We implemented a hypothesis-driven approach using logistic regression and a data-driven approach using machine learning to examine distinct but related measures of personality functioning as predictors of antisocial cognitions.

Results

Antisocial cognitions were associated with low interpersonal functioning as expected, but only when not adjusting for antisocial traits, which accounted for almost all the association. The data-driven analysis revealed that individual items assessing empathic concern in personality functioning scales (as opposed to the whole scores) explained low antisocial cognitions even when adjusting for antisocial traits.

Discussion

Antisocial cognitions appear to be associated to two distinct traits, the antisocial and a specific type of personality functioning. This finding is discussed in terms of the possible distinction between two motivational forces: to harm others/prioritize one's advantage, and to help suffering others.

Beyond physical sensations: investigating empathy and prosocial behavior in vicarious pain responders

Empathy, the capacity to share others' emotional experiences, has been proposed as a key motivation for altruistic behavior in both humans and animals. Sharing another's emotional experience may generate a self-embodied simulation of their emotional state, fostering understanding and promoting prosocial behavior. Vicarious pain responders report sensing physical pain when observing others in pain. Whether this ability extends to emotional experiences remains unexplored. Using both questionnaires and ecologically valid behavioral tasks, we explored whether vicarious pain responders differ from nonresponders in empathic abilities and prosocial behavior. Participants watched video clips of people describing a negative emotional life event. We operationalized several empathic abilities and responses (empathic accuracy, affective synchrony, emotional reaction, and empathic motivation) based on participants' and targets' responses during and after watching the videos. Participants were also engaged in a donation task measuring tendency for prosocial behavior. Findings reveal that compared to nonresponders, vicarious pain responders exhibit enhanced empathic accuracy, intensified emotional reactions to others' emotional pain, and a greater motivation to communicate with the target. This study marks the first behavioral evidence showcasing vicarious pain responders' empathic abilities, reactions, and motivation in response to nonphysical pain of others, expanding our knowledge of this phenomenon and its association with broader empathic abilities.

Sexually dimorphic control of affective state processing and empathic behaviors

Recognizing the affective states of social counterparts and responding appropriately fosters successful social interactions. However, little is known about how the affective states are expressed and perceived and how they influence social decisions. Here, we show that male and female mice emit distinct olfactory cues after experiencing distress. These cues activate distinct neural circuits in the piriform cortex (PiC) and evoke sexually dimorphic empathic behaviors in observers. Specifically, the PiC → PrL pathway is activated in female observers, inducing a social preference for the distressed counterpart. Conversely, the PiC → MeA pathway is activated in male observers, evoking excessive self-grooming behaviors. These pathways originate from non-overlapping PiC neuron populations with distinct gene expression signatures regulated by transcription factors and sex hormones. Our study unveils how internal states of social counterparts are processed through sexually dimorphic mechanisms at the molecular, cellular, and circuit levels and offers insights into the neural mechanisms underpinning sex differences in higher brain functions.

Age and parous-experience dependent changes in emotional contagion for positive infant sounds

Introduction

Emotional contagion is achieved by inferring and emotionally resonating with other persons' feelings. It is unclear whether age-related changes in emotional contagion for infant sounds are modulated by the experience of childbirth or childcare. This study aims to evaluate changes in inference and emotional resonance for positive and negative infant sounds (laughter and crying) among women, based on age and parous experience.

Methods

A total of 241 women (60 young nulliparous, 60 young parous, 60 old nulliparous, and 61 old parous) completed a web-based questionnaire. After listening to three types of infant sounds (laughter, cooing, and crying), participants responded with their valence for hearing infant sounds and estimated infant valence on an 11-point Likert scale.

Results

The analysis for emotional resonance revealed that the correlation coefficient between self and estimated infant valences was greater in young parous and old nulliparous women than in young nulliparous women, in laughter and cooing sounds. However, correlation coefficients for crying did not differ among any of the four groups.

Conclusion

The degree of emotional resonance for infant valence increased depending on age and parous-experience for positive infant sounds.

Normative values and diagnostic optimisation of three social cognition measures for autism and schizophrenia diagnosis in a healthy adolescent and adult sample

Awareness of the importance of assessing social cognition skills under conditions showing atypical social behaviours has increased over the years. However, the evaluation of the psychometric properties of the measures and the availability of normative values for the clinical context are still limited. This study aims to revise, provide normative values, and evaluate the clinical validity of the Italian version of three social cognition measures: Advanced Theory of Mind (A-ToM) task, the Emotion Attribution Task (EAT), and the Social Situation Task (SST). Measures were administered to 580 adolescents and adult healthy controls (age range 14-50). We performed differential item functioning and Rasch analysis to revise each task, so normative data of the revised measures were calculated. Moreover, the revised measures were administered to 38 individuals with autism spectrum disorder (ASD) and 35 individuals with schizophrenia spectrum disorders (SSD): ASD and SSD were matched by age, gender, and IQ with a control sample to evaluate clinical validity. ROC analysis showed that the SST is the best measure differentiating between healthy and clinical groups, compared to the A-ToM (AUCASD = 0.70; AUCSSD = 0.65) and EAT (AUCASD = 0.67; AUCSSD = 0.50), which showed poorer performance. For SSD diagnosis, two SST subscales (Violation and Gravity score) indicated the best accuracy (AUCs of 0.88 and 0.84, respectively); for the ASD diagnosis, we propose a combined score between the SST subscale and A-ToM (AUC = 0.86). The results suggest that the proposed measures can be used to support the diagnostic process and clinical practice.

The role of external factors in affect-sharing and their neural bases

Affect-sharing, the ability to vicariously feel another person's emotions, is the primary component of empathy that is typically thought to rely on the observer's capacity to feel the emotions of others. However, external signals, such as the target's physical characteristics, have been demonstrated to influence affect-sharing in the neuroscientific literature that speaks to the underappreciated role of external factors in eliciting affect-sharing. We consider factors that influence affect-sharing, including physical cues, emotional cues, situational factors, and observer-target relationships, as well as the neural circuits involved in these processes. Our review reveals that, while neural network activation is primarily responsible for processing affect-sharing, external factors also co-activate a top-down cognitive processing network to modulate the conscious process of affect-sharing. From this knowledge, an integrative framework of external factor interactions with affect-sharing are explained in detail. Finally, we identify critical areas for future research in social and affective neuroscience, including research gaps and incorporation of ecologically valid paradigms.

An in-depth analysis of the polyvagal theory in light of current findings in neuroscience and clinical research

The polyvagal theory has led to the understanding of the functions of the autonomic nervous system in biological development in humans, since the vagal system, a key structure within the polyvagal theory, plays a significant role in addressing challenges of the mother-child dyad. This article aims to summarize the neurobiological aspects of the polyvagal theory, highlighting some of its strengths and limitations through the lens of new evidence emerging in several research fields-including comparative anatomy, embryology, epigenetics, psychology, and neuroscience-in the 25 years since the theory's inception. Rereading and incorporating the polyvagal idea in light of modern scientific findings helps to interpret the role of the vagus nerve through the temporal dimension (beginning with intrauterine life) and spatial dimension (due to the numerous connections of the vagus with various structures and systems) in the achievement and maintenance of biopsychosocial well-being, from the uterus to adulthood.

EEG evidence for racial ingroup bias in collective empathy for pain

Previous research on racial ingroup bias in empathy for pain focused on neural responses to a single person's suffering. It is unclear whether empathy for simultaneously perceived multiple individuals' pain (denoted as collective empathy in this study) is also sensitive to perceived racial identities of empathy targets. We addressed this issue by recording electroencephalography from Chinese adults who responded to racial identities of 2 × 2 arrays of Asian or White faces in which 4 faces, 1 face, or no face showed painful expressions. Participants reported greater feelings of others' pain and their own unpleasantness when viewing 4 compared to 1 (or no) painful faces. Behavioral responses to racial identities of faces revealed decreased speeds of information acquisition when responding to the face arrays with 4 (vs. 1 or no) painful expressions of Asian (but not White) faces. Moreover, Asian compared to White face arrays with 4 (vs. 1 or no) painful expressions elicited a larger positive neural response at 160-190 ms (P2) at the frontal/central electrodes and enhanced alpha synchronizations at 288-1,000 ms at the central electrodes. Our findings provide evidence for racial ingroup biases in collective empathy for pain and unravel its relevant neural underpinnings.

Exploring Actual and Presumed Links between Accurately Inferring Contents of Other People's Minds and Prosocial Outcomes

The term "empathic accuracy" has been applied to people's ability to infer the contents of other people's minds-that is, other people's varying feelings and/or thoughts over the course of a social interaction. However, despite the ease of intuitively linking this skill to competence in helping professions such as counseling, the "empathic" prefix in its name may have contributed to overestimating its association with prosocial traits and behaviors. Accuracy in reading others' thoughts and feelings, like many other skills, can be used toward prosocial-but also malevolent or morally neutral-ends. Prosocial intentions can direct attention towards other people's thoughts and feelings, which may, in turn, increase accuracy in inferring those thoughts and feelings, but attention to others' thoughts and feelings does not necessarily heighten prosocial intentions, let alone outcomes.

The Association Between Emotional Expressions and Empathic Accuracy

Empathic accuracy, the ability to accurately represent and understand another's emotional state, is integral to socio-emotional functioning. It is also inherently an interpersonal process that requires active engagement of the emotional systems of both interaction partners. The emotional expressivity of the partner sharing their emotions restricts empathic accuracy and the perceiver's emotional expressivity might also affect empathic accuracy as they behaviorally simulate and thus share the emotions they see in the other's face. We explored a potential role of emotional expressivity in people's ability to understand another's emotions in a face-to-face dyadic interaction. Participants took turns sharing emotional experiences while their facial expressions were recorded. They then watched the recordings while continuously rating their own and their partner's affect at any given point during the recording. Empathic accuracy was indexed as the epoch by-epoch emotion change detection. We found that emotional expressivity of the listener, but not of the partner, was associated with increased empathic accuracy, even when controlling for partner's expressivity. Our findings highlight the active role the person empathizing takes in face-to-face emotional sharing.

An investigation of the modulatory effects of empathic and autistic traits on emotional and facial motor responses during live social interactions

A close relationship between emotional contagion and spontaneous facial mimicry has been theoretically proposed and is supported by empirical data. Facial expressions are essential in terms of both emotional and motor synchrony. Previous studies have demonstrated that trait emotional empathy enhanced spontaneous facial mimicry, but the relationship between autistic traits and spontaneous mimicry remained controversial. Moreover, previous studies presented faces that were static or videotaped, which may lack the "liveliness" of real-life social interactions. We addressed this limitation by using an image relay system to present live performances and pre-recorded videos of smiling or frowning dynamic facial expressions to 94 healthy female participants. We assessed their subjective experiential valence and arousal ratings to infer the amplitude of emotional contagion. We measured the electromyographic activities of the zygomaticus major and corrugator supercilii muscles to estimate spontaneous facial mimicry. Individual differences measures included trait emotional empathy (empathic concern) and the autism-spectrum quotient. We did not find that live performances enhanced the modulatory effect of trait differences on emotional contagion or spontaneous facial mimicry. However, we found that a high trait empathic concern was associated with stronger emotional contagion and corrugator mimicry. We found no two-way interaction between the autism spectrum quotient and emotional condition, suggesting that autistic traits did not modulate emotional contagion or spontaneous facial mimicry. Our findings imply that previous findings regarding the relationship between emotional empathy and emotional contagion/spontaneous facial mimicry using videos and photos could be generalized to real-life interactions.
