RESUMO
INTRODUCTION: The alternative model for personality disorders (AMPD) of the Diagnostic and Statistical Manual of Mental Disorders - 5th edition (DSM-5) considers impairments in empathy a basic feature of personality disorders (PDs). In contrast, the AMPD pathological personality trait model and the categorical DSM-5 Section II PD model associate deficits in empathy to specific forms of personality pathology. The present study investigated to what extent impairments in cognitive and emotional empathy are markers of general versus specific personality pathology. METHODS: In a clinical sample (n = 119), the Multifaceted Empathy Test was used to assess cognitive empathy, emotional empathy for positive emotions, and emotional empathy for negative emotions. Personality functioning, pathological personality traits, and DSM-5 Section II PDs were assessed via interviews and self-reports. Confirmatory factor analyses were applied to associate the three empathy facets with the three personality pathology approaches, each modeled with general personality pathology (common factor) and specific personality pathology (residuals of indicators). RESULTS: Impairments in cognitive empathy and emotional empathy for positive emotions were significantly correlated with general personality pathology. All three empathy facets were also correlated to specific personality pathology when controlling for general personality pathology, respectively. Impairments in cognitive empathy were incrementally associated with identity and empathy (personality functioning), psychoticism (pathological personality traits), and paranoid and dependent PD (DSM-5 Section II PDs). Deficits in emotional empathy for positive emotions were incrementally associated with self-direction and intimacy (personality functioning) and detachment (pathological personality traits). Impairments in emotional empathy for negative emotions were incrementally associated with antagonism (pathological personality traits) and antisocial PD (DSM-5 Section II PDs). CONCLUSION: The results suggest that impairments in cognitive empathy and emotional empathy for positive emotions, but not for negative emotions, are markers of general personality pathology, while deficits in the three empathy facets are also markers for specific personality pathology.

BACKGROUND: Patient and public involvement (PPI) describes the participation of patients and relatives, i.e., experts by experience (EE), in the research process. The PPI has not been widely adopted in the fields of medicine and clinical psychology in Germany and there is a notable absence of institutional support. The German Center for Mental Health (DZPG), which has been under construction since May 2023, aims to achieve nationwide and cross-center implementation of PPI, constituting one of its primary objectives. Participation of EE is to be implemented in the DZPG at all levels of decision-making. OBJECTIVES: The article describes the origins, development and challenges associated with the implementation of participation structures and projects in the DZPG. The central political PPI committee in the DZPG, the Trilogue Center Council (TZR), developed a comprehensive PPI strategy for the DZPG in almost 3 years of work, before the beginning of the financial support of the DZPG. Among various measures, the strategy entails establishing a far-reaching representation for EE in all decision-making bodies of the DZPG, to involve EE as reviewers in evaluating research proposals, to integrate participatory elements into all studies of the DZGG and to foster user-initiated research endeavors. The implementation of the strategy is ensured by a cross-center PPI infrastructure, the Center for PPI, and scientific PPI consultants. The Center for PPI's tasks include supporting the voice of the EE and developing instruments and guidelines for participatory research, bringing together EE and researchers for joint DZPG projects as well as the documentation and quality assurance for participatory research. One of the particular challenges for the successful implementation of the PPI strategy is the limited experience with PPI in Germany in the field of mental health research and the widespread lack of structural implementation. Currently developed solution strategies include training for researchers and EE to communicate the benefits and pathways in the realization of PPI and thus enable shared decision-making and research. In addition, extensive access to knowledge and resources for EE will be created and uniform remuneration regulations for EE will be developed. CONCLUSION: A PPI strategy at the DZPG has been successfully developed and is currently being implemented by the cross-center infrastructure Center for PPI.

BACKGROUND: We propose and evaluate a contribution to the conceptualization and assessment of personality functioning based on social domains and mentalizing hypotheses. Social domains are distinct social contexts, such as with acquaintances and friends, with differentiated expectations regarding participants' behaviours and social attributions. The capacity to organize social participation according to these expectations requires the ability, we suggest, to modulate mentalizing processes domain by domain. Drawing on evidence that social domain organization is impaired in borderline personality disorder (BPD) and that hypermentalizing, a heightened interpretation of others' motives, thoughts or emotions, is elevated in adolescent BPD, we hypothesized that hypermentalizing levels in adolescents will vary by social domain and that elevated BPD features will be associated with impairment of this domain organization of hypermentalizing. METHODS: Measures including the borderline personality features scale for children (BPFSC) and the movie for the assessment of social cognition (MASC) were administered to 171 adolescents aged 12-17 recruited from public schools and community organizations in a large metropolitan area in southwestern United States. Mean hypermentalizing scores were computed for adolescent interpretations of sequences in the MASC focusing on the social domains of acquaintance, friends and romantic interactions. RESULTS: There was a progressive increase in hypermentalizing scores across the acquaintance, friends and romantic interactions (repeated measures ANOVA, p < .001, all pairwise comparisons, p ≤ .02), which was markedly reduced in the presence of elevated BPD features (interaction term, p = .007). CONCLUSIONS: Hypermentalizing is organized according to social domain and this organization is impaired in the presence of elevated BPD features. The findings are consistent with the proposal that personality functioning entails a social domains organization of hypermentalizing, which is impaired in personality dysfunction. Identifying mentalizing processes domain by domain has the potential to create a personalized focus for the treatment of adolescents with personality difficulties.

BACKGROUND: While witnessing the suffering of other people results in personal distress, it is not clear whether regulating others' emotions in such situations also comes at an emotional cost for the observer. METHODS: This study included 62 subjects and used a newly developed functional Magnetic Resonance Imaging (fMRI) paradigm to investigate mechanisms of self and other emotion regulation via reappraisal while the subject and an interaction partner outside the scanner were facing the same distressing situation simultaneously. The relationship between distress levels and individual differences in emotional and cognitive empathy were also assessed. RESULTS: We found that individuals exhibited especially high levels of personal distress when relating with a partner while both being exposed to aversive photographs and that especially highly empathetic individuals were prone to such personal distress. Moreover, when engaging in social emotion regulation, personal distress was reduced in the observer at a similar rate as in self emotion regulation. FMRI analyses revealed increased activation for other vs. self emotion regulation in the precuneus and the left temporo-parietal junction, which are commonly engaged in social cognition. Furthermore, this activation was associated with lower self-reported stress and decreased sympathetic autonomic activity. While regulating others, precuneus activation exhibited a distinctive functional connectivity profile with parietal emotion regulation regions. CONCLUSIONS: This study demonstrates benefits of actively regulating another person's emotions for reducing one's own distress and identifies the precuneus as an important node for social emotion regulation. Given the novelty of the study design, the results are of exploratory and preliminary nature.

Although much research has shown that mindfulness-based interventions (MBIs) can reduce psychological stress, it is less clear if effects generalize to everyday social situations, which range among the largest stress triggers. Furthermore, mechanisms of MBIs have not been fully established. Emotion regulation (ER) has been suggested as one key mechanism, yet the role of cognitive reappraisal and acceptance strategies is still under debate. To address these questions, a neuroimaging-based randomized controlled trial (RCT) was performed (n=68), comparing mindfulness-based stress reduction (MBSR) with a reading/listening intervention (READ), using a novel dyadic paradigm for self and other emotion regulation under stress as primary outcome on behavior and brain levels and established empathy measures (clinicatrials.gov NCT03035669). Compared to READ, MBSR led to self-reported stress reduction through both cognitive reappraisal and acceptance only when regulating self and not when regulating others' distress. In addition, MBSR led to increased brain activation over time for regulating own (parietal cortex) and others' (precuneus, TPJ) emotions through cognitive reappraisal and acceptance, albeit this effect was also seen for the reading intervention for regulating own stress via reappraisal. Brain changes did not scale with subjective stress reduction and amount of meditation practice. More distant generalization effects of MBSR on socio-emotional functioning (cognitive empathy and compassion) could also not be shown. This study identified both cognitive reappraisal and acceptance as two ER mechanisms of MBSR, but indicates that effects do not extend to social settings.

Successful parenting requires constant inferring of affective states. Especially vital is the correct identification of facial affect. Previous studies have shown that infant faces are processed preferentially compared to adult faces both on the behavioural and the neural level. This study specifically investigates the child-evoked neural responses to affective faces and their modulation by motherhood and attention to affect. To do so, we used a paradigm to measure neural responses during both explicit and implicit facial affect recognition (FAR) in mothers and non-mothers using child and adult faces. Increased activation to child compared to adult faces was found for mothers and non-mothers in face processing areas (bilateral fusiform gyri) and areas associated with social understanding (bilateral insulae and medial superior frontal gyrus) when pooling implicit and explicit affect recognition. Furthermore, this child-evoked activation was modulated by motherhood with an increase in mothers compared to non-mothers in the left precuneus. Additionally, explicitly recognising the affect increased child-evoked activation in the medial superior frontal gyrus in both mothers and non-mothers. These results suggest preferential treatment of affective child over adult faces, modulated by motherhood and attention to affect.

The faces of those most personally relevant to us are our primary source of social information, making their timely perception a priority. Recent research indicates that gender, age and identity of faces can be decoded from EEG/MEG data within 100 ms. Yet, the time course and neural circuitry involved in representing the personal relevance of faces remain unknown. We applied simultaneous EEG-fMRI to examine neural responses to emotional faces of female participants' romantic partners, friends, and a stranger. Combining EEG and fMRI in cross-modal representational similarity analyses, we provide evidence that representations of personal relevance start prior to structural encoding at 100 ms, with correlated representations in visual cortex, but also in prefrontal and midline regions involved in value representation, and monitoring and recall of self-relevant information. Our results add to an emerging body of research that suggests that models of face perception need to be updated to account for rapid detection of personal relevance in cortical circuitry beyond the core face processing network.

OBJECTIVES: Childhood trauma constitutes a major risk factor for adult psychopathology, including posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and somatic symptom disorder (SSD). One potential mechanism linking childhood trauma to adult psychopathology may be alterations in theory of mind (ToM). Given the lack of transdiagnostic studies on the association between childhood trauma and ToM, further research is needed to elucidate whether and how childhood trauma relates to ToM impairments across and within diagnostic boundaries. DESIGN: A cross-sectional study design was applied. METHODS: A total of 137 individuals with varying levels of childhood trauma took part in this study, encompassing individuals with PTSD (n = 33), MDD (n = 33), SSD (n = 36), and healthy volunteers (HVs; n = 35). To assess ToM performance and childhood trauma, the Movie for the Assessment of Social Cognition was administered along with the Childhood Trauma Questionnaire. RESULTS: Only individuals with PTSD, but not individuals with MDD or SSD, showed a worse ToM performance compared to HVs. In the whole sample, childhood trauma correlated negatively with ToM performance. Exploratory group-specific analyses revealed higher levels of childhood trauma to be associated with more excessive ToM errors in individuals with SSD, and notably with an enhanced ToM performance in individuals with MDD. CONCLUSIONS: Our results indicate associations between childhood trauma and ToM impairments in a large, transdiagnostic sample. Provided replication in future studies, our findings suggest ToM capacities as a promising treatment target for individuals exposed to severe childhood trauma, at least or particularly with a diagnosis of PTSD. PRACTITIONER POINTS: Our results suggest that individuals with a history of severe childhood trauma, at least or particularly with a clinical diagnosis of posttraumatic stress disorder, may benefit from therapeutic approaches targeting theory of mind capacities. Our findings indicate that higher levels of childhood trauma may be linked to a specific 'hypermentalizing' bias in somatic symptom disorder. Our findings further point towards an association between higher levels of childhood trauma and a heightened - rather than a diminished - sensitivity towards interpersonal cues in major depressive disorder. Provided further confirmatory evidence, our findings may support diagnosis-specific approaches in ameliorating theory of mind abilities in individuals with different mental disorders and a history of severe childhood trauma.

Parenting requires mothers to read social cues and understand their children. It is particularly important that they recognise their child's emotions to react appropriately, for example, with compassion to sadness or compersion to happiness. Despite this importance, it is unclear how motherhood affects women's ability to recognise emotions associated with facial expressions in children. Using videos of an emotionally neutral face continually and gradually taking on a facial expression associated with an emotion, we quantified the amount of information needed to match the emotion with the facial expression. Mothers needed more information than non-mothers to match the emotions with the facial expressions. Both mothers and non-mothers performed equally on a control task identifying animals instead of emotions, and both groups needed less information when recognising the emotions associated with facial expressions in adolescents than pre-schoolers. These results indicate that mothers need more information for to correctly recognise typically associated emotions in child facial expressions but not for similar tasks not involving emotions. A possible explanation is that child facial expressions associated with emotions may have a greater emotional impact on mothers than non-mothers leading to task interference but possibly also to increased compassion and compersion.

The ability to recognize emotions from facial expressions is crucial for social interaction. Only few studies have examined the effect of stress hormones on facial emotion recognition, although stressful events affect social interactions on a daily basis. Those studies that examined facial emotion recognition mostly used explicit prompts to trigger consciously controlled processing. However, facial emotions are processed mainly implicitly in real life. Therefore, we investigated separate and combined effects of noradrenergic and glucocorticoid stimulation on implicit and explicit facial emotion recognition. One hundred and four healthy men (mean age = 24.1 years ±SD 3.5) underwent the Face Puzzle task to test implicit and explicit facial emotion recognition after receiving either 10 mg hydrocortisone or 10 mg yohimbine (an alpha 2-adrenergic receptor antagonist that increases noradrenergic activity) or 10 mg hydrocortisone/10 mg yohimbine combined or placebo. Salivary cortisol and salivary alpha amylase (sAA) were measured during the experiment. Compared to the placebo condition hydrocortisone significantly increased salivary cortisol and yohimbine significantly increased sAA. Participants were better and faster in explicit than in implicit facial emotion recognition. However, there was no effect of separate and combined noradrenergic and glucocorticoid stimulation on implicit and explicit facial emotion recognition performance compared to placebo. Our results do not support an essential role of the glucocorticoid and noradrenergic system in FER in young healthy men.

The level of functioning of individuals with autism spectrum disorder (ASD) varies widely. To better understand the neurobiological mechanism associated with high-functioning ASD, we studied the rare case of a female patient with an exceptional professional career in the highly competitive academic field of Mathematics. According to the Research Domain Criteria (RDoC) approach, which proposes to describe the basic dimensions of functioning by integrating different levels of information, we conducted four fMRI experiments targeting the (1) social processes domain (Theory of mind (ToM) and face matching), (2) positive valence domain (reward processing), and (3) cognitive domain (N-back). Patient's data were compared to data of 14 healthy controls (HC). Additionally, we assessed the subjective experience of our case during the experiments. The patient showed increased response times during face matching and achieved a higher total gain in the Reward task, whereas her performance in N-back and ToM was similar to HC. Her brain function differed mainly in the positive valence and cognitive domains. During reward processing, she showed reduced activity in a left-hemispheric frontal network and cortical midline structures but increased connectivity within this network. During the working memory task patients' brain activity and connectivity in left-hemispheric temporo-frontal regions were elevated. In the ToM task, activity in posterior cingulate cortex and temporo-parietal junction was reduced. We suggest that the high level of functioning in our patient is rather related to the effects in brain connectivity than to local cortical information processing and that subjective report provides a fruitful framework for interpretation.

Research in social cognition has shown that our own emotional experiences are an important source of information to understand what other people are feeling. The current study investigated whether individuals project their own affective states when reading other's emotional expressions. We used brief autobiographical recall and audiovisual stimuli to induce happy, neutral and sad transient states. After each emotion induction, participants made emotion judgments about ambiguous faces displaying a mixture of happiness and sadness. Using an adaptive psychophysics procedure, we estimated the tendency to perceive the faces as happy under each of the induced affective states. Results demonstrate the occurrence of egocentric projections, such that faces were more likely judged as happy when participants reported being happy as compared to when they were sad. Moreover, the degree of emotional egocentricity was associated with individual differences in perspective-taking, with smaller biases being observed in individuals with higher disposition to take the perspective of others. Our findings extend previous literature on emotional egocentricity by showing that self-projection occurs when we make emotion attributions based on the other's emotional expressions, and supports the notion that perspective-taking tendencies play a role in the ability to understand the other's affective states.

A number of prominent theories have linked tendencies to mimick others' facial movements to empathy and facial emotion recognition, but evidence for such links is uneven. We conducted a meta-analysis of correlations of facial mimicry with empathy and facial emotion recognition skills. Other factors were also examined for moderating influence, e.g. facets of empathy measured, facial muscles recorded, and facial emotions being mimicked. Summary effects were estimated with a random-effects model and a meta-regression analysis was used to identify factors moderating these effects. 162 effects from 28 studies were submitted. The summary effect size indicated a significant weak positive relationship between facial mimicry and empathy, but not facial emotion recognition. The moderator analysis revealed that stronger correlations between facial mimicry and empathy were observed for static vs. dynamic facial stimuli, and for implicit vs. explicit instances of facial emotion processing. No differences were seen between facial emotions, facial muscles, emotional and cognitive facets of empathy, or state and trait measures of empathy. The results support the claim that stronger facial mimicry responses are positively related to higher dispositions for empathy, but the weakness and variability of this effect suggest that this relationship is conditional on not-fully understood factors.

BACKGROUND: The promise of precision medicine for autism spectrum disorder (ASD) hinges on developing neuroscience-informed individualized interventions. Taking an important step in this direction, we investigated neuroplasticity in response to an ecologically-valid, computer-based social-cognitive training (SCOTT). METHODS: In an active control group design, 48 adults with ASD were randomly assigned to a 3-month SCOTT or non-social computer training. Participants completed behavioral tasks, a functional and structural magnetic resonance imaging session before and after the training period. RESULTS: The SCOTT group showed social-cognitive improvements on close and distant generalization tasks. The improvements scaled with reductions in functional activity and increases in cortical thickness in prefrontal regions. CONCLUSION: In sum, we provide evidence for the sensitivity of neuroscientific methods to reflect training-induced social-cognitive improvements in adults with ASD. These results encourage the use of neuroimaging data to describe and quantify treatment-related changes more broadly.

BACKGROUND: The atypical processing of eye contact is a characteristic hallmark of autism spectrum disorder (ASD). The severity of these symptoms, however, is thought to lie on a continuum that extends into the typical population. While behavioural evidence shows that differences in social cognitive tasks in typically developed (TD) adults are related to the levels of autistic-like traits, it remains unknown whether such a relation exists for the sensitivity to direct gaze. METHODS: In two experiments, we measured reaction times to detect the faces with direct and averted gaze, suppressed from awareness, i.e. the access to awareness. In experiment 1, we tested N = 19 clinically diagnosed adults with ASD and N = 22 TD matched controls, while in experiment 2, we tested an independent sample of N = 20 TD adults. RESULTS: In line with the literature, experiment 1 showed preferential processing of direct gaze in the TD group but not in the ASD group. Importantly, we found a linear relationship in both experiments between the levels of autistic traits within the groups of TD participants and their sensitivity to direct gaze: with increasing autistic characteristics, there was a decrease in sensitivity to direct gaze. CONCLUSION: These results provide the first evidence that differences in gaze processing and the sensitivity to direct gaze are already present in individuals with subclinical levels of autistic traits. Furthermore, they lend support to the continuum view of the disorder and could potentially help in an earlier diagnosis of individuals at high risk for autism.

Despite advances in the conceptualisation of facial mimicry, its role in the processing of social information is a matter of debate. In the present study, we investigated the relationship between mimicry and cognitive and emotional empathy. To assess mimicry, facial electromyography was recorded for 70 participants while they completed the Multifaceted Empathy Test, which presents complex context-embedded emotional expressions. As predicted, inter-individual differences in emotional and cognitive empathy were associated with the level of facial mimicry. For positive emotions, the intensity of the mimicry response scaled with the level of state emotional empathy. Mimicry was stronger for the emotional empathy task compared to the cognitive empathy task. The specific empathy condition could be successfully detected from facial muscle activity at the level of single individuals using machine learning techniques. These results support the view that mimicry occurs depending on the social context as a tool to affiliate and it is involved in cognitive as well as emotional empathy.

OBJECTIVES: Analysis of the causes of challenging behavior in individuals with intellectual disability (ID). METHODS: The relatedness and the impact of cognitive and emotional functioning on challenging behavior was investigated by correlation and regression analyses in 262 individuals with ID and mental disordersâ/âchallenging behavior. RESULTS: Despite the high correlation between ID and emotional development, cognitive-emotional developmental discrepancies were found in every second patient. The severity of challenging behavior was associated with a lower level of emotional development, especially in the area of "aggression regulation". CONCLUSION: The level of emotional development should be ascertained in the context of an assessment of challenging behavior in individuals with ID.

Background: The empathogen 3,4-methylenedioxymethamphetamine (MDMA) is the prototypical prosocial club drug inducing emotional openness to others. It has recently been shown that acutely applied 3,4-MDMA in fact enhances emotional empathy and prosocial behavior, while it simultaneously decreases cognitive empathy. However, the long-term effects of 3,4-MDMA use on socio-cognitive functions and social interactions have not been investigated yet. Therefore, we examined emotional and cognitive empathy, social decision-making, and oxytocin plasma levels in chronic 3,4-MDMA users. Methods: We tested 38 regular but recently abstinent 3,4-MDMA users and 56 3,4-MDMA-naïve controls with the Movie for the Assessment of Social Cognition, the Multifaceted Empathy Test, and the Distribution Game and the Dictator Game. Drug use was objectively quantified by 6-month hair analyses. Furthermore, oxytocin plasma levels were determined in smaller subgroups (24 3,4-MDMA users, 9 controls). Results: 3,4-MDMA users showed superior cognitive empathy compared with controls in the Multifaceted Empathy Test (Cohen's d=.39) and in the Movie for the Assessment of Social Cognition (d=.50), but they did not differ from controls in emotional empathy. Moreover, 3,4-MDMA users acted less self-serving in the Distribution Game. However, within 3,4-MDMA users, multiple regression analyses showed that higher 3,4-MDMA concentrations in hair were associated with lower cognitive empathy (ßMDMA=-.34, t=-2.12, P<.05). Oxytocin plasma concentrations did not significantly differ between both groups. Conclusions: We conclude that people with high cognitive empathy abilities and pronounced social motivations might be more prone to 3,4-MDMA consumption. In contrast, long-term 3,4-MDMA use might nevertheless have a detrimental effect on cognitive empathy capacity.

Background: Impaired empathic abilities lead to severe negative social consequences and influence the development and treatment of several psychiatric disorders. Furthermore, empathy has been shown to play a crucial role in moral and prosocial behavior. Although the serotonin system has been implicated in modulating empathy and moral behavior, the relative contribution of the various serotonin receptor subtypes is still unknown. Methods: We investigated the acute effect of psilocybin (0.215 mg/kg p.o.) in healthy human subjects on different facets of empathy and hypothetical moral decision-making using the multifaceted empathy test (n=32) and the moral dilemma task (n=24). Results: Psilocybin significantly increased emotional, but not cognitive empathy compared with placebo, and the increase in implicit emotional empathy was significantly associated with psilocybin-induced changed meaning of percepts. In contrast, moral decision-making remained unaffected by psilocybin. Conclusions: These findings provide first evidence that psilocybin has distinct effects on social cognition by enhancing emotional empathy but not moral behavior. Furthermore, together with previous findings, psilocybin appears to promote emotional empathy presumably via activation of serotonin 2A/1A receptors, suggesting that targeting serotonin 2A/1A receptors has implications for potential treatment of dysfunctional social cognition.

Deep brain stimulation (DBS) is a promising approach in treatment-resistant depression (TRD). TRD is associated with problems in interpersonal relationships, which might be linked to impaired empathy. Here, we investigate the influence of DBS in the subgenual anterior cingulate cortex (sgACC) on empathy in patients with TRD and explore the pattern of oscillatory sgACC activity during performance of the multifaceted empathy test. We recorded local field potential activity directly from sgACC via DBS electrodes in patients. Based on previous behavioral findings, we expected disrupted empathy networks. Patients showed increased empathic involvement ratings toward negative stimuli as compared with healthy subjects that were significantly reduced after 6 months of DBS. Stimulus-related oscillatory activity pattern revealed a broad desynchronization in the beta (14-35 Hz) band that was significantly larger during patients' reported emotional empathy for negative stimuli than when patients reported to have no empathy. Beta desynchronization for empathic involvement correlated with self-reported severity of depression. Our results indicate a "negativity bias" in patients that can be reduced by DBS. Moreover, direct recordings show activation of the sgACC area during emotional processing and propose that changes in beta-band oscillatory activity in the sgACC might index empathic involvement of negative emotion in TRD.
