Social preferences and psychopathy in a sample of male prisoners-a pilot study.

Social decisions are influenced by a person's social preferences. High psychopathy is defined by antisocial behaviour, but the relationship between psychopathy and social preferences remains unclear. In this study, we used a battery of economic games to study social decision-making and social preferences in relation to psychopathy in a sample of 35 male prison inmates, who were arrested for sexual and severe violent offenses (mean age = 39 years). We found no evidence for a relationship between social preferences (measured with the Dictator and Ultimatum Games, Social Value Orientation, and one-shot 2 × 2 games) and psychopathy (measured by the overall Hare Psychopathy Checklist-Revised score and both factors). These results are surprising but also difficult to interpret due to the small sample size. Our results contribute to the ongoing debate about psychopathy and social decision-making by providing crucial data that can be combined with future datasets to reach large sample sizes that can provide a more nuanced understanding about the relationship between psychopathy and social preferences.

Robot-assisted surgery and artificial intelligence-based tumour diagnostics: social preferences with a representative cross-sectional survey.

BACKGROUND: The aim of this study was to assess social preferences for two different advanced digital health technologies and investigate the contextual dependency of the preferences. METHODS: A cross-sectional online survey was performed among the general population of Hungary aged 40 years and over. Participants were asked to imagine that they needed a total hip replacement surgery and to indicate whether they would prefer a traditional or a robot-assisted (RA) hip surgery. To better understand preferences for the chosen method, the willingness to pay (WTP) method was used. The same assessment was conducted for preferences between a radiologist's and AI-based image analysis in establishing the radiological diagnosis of a suspected tumour. Respondents' electronic health literacy was assessed with the eHEALS questionnaire. Descriptive methods were used to assess sample characteristics and differences between subgroups. Associations were investigated with correlation analysis and multiple linear regressions. RESULTS: Altogether, 1400 individuals (53.7% female) with a mean age of 58.3 (SD = 11.1) years filled in the survey. RA hip surgery was chosen by 762 (54.4%) respondents, but only 470 (33.6%) chose AI-based medical image evaluation. Those who opted for the digital technology had significantly higher educational levels and electronic health literacy (eHEALS). The majority of respondents were willing to pay to secure their preferred surgical (surgeon 67.2%, robot-assisted: 68.8%) and image assessment (radiologist: 70.9%; AI: 77.4%) methods, reporting similar average amounts in the first (p = 0.677), and a significantly higher average amount for radiologist vs. AI in the second task (p = 0.001). The regression showed a significant association between WTP and income, and in the hip surgery task, it also revealed an association with the type of intervention chosen. CONCLUSIONS: Individuals with higher education levels seem to accept the advanced digital medical technologies more. However, the greater openness for RA surgery than for AI image assessment highlights that social preferences may depend considerably on the medical situation and the type of advanced digital technology. WTP results suggest rather firm preferences in the great majority of the cases. Determinants of preferences and real-world choices of affected patients should be further investigated in future studies.

Understanding the Function of Challenging Behavior and Related Intervention and Strategies.

People with intellectual disability or related neurodevelopmental disorders may present the full range of psychiatric and behavioral disorders seen in the general population. In fact, research has shown that they are more susceptible to presenting psychiatric disorders and/or challenging behaviors. When a person with intellectual disability or a related neurodevelopmental disorder exhibits challenging behaviors, it is important to identify the underlying causes. These causes may be multifactorial. In this article we briefly discuss the elements of conducting a comprehensive assessment of the function of presenting challenging behaviors. This multifunctional assessment must include assessing for the presence of physical health problems, an undiagnosed oral health problem, psychiatric disorders, the level of sensory stimuli in the environment, and conclude with an evaluation of antecedents and consequences that may be contributing to a learned behavior. An important resultant of the information gained from this comprehensive functional assessment are intervention strategies that should target the function of the challenging behaviors and lead to reducing these challenging behaviors by addressing the need that they serve.

Two is company: The posterior cerebellum and sequencing for pairs versus individuals during social preference prediction.

Previous studies have identified that the posterior cerebellum, which plays a role in processing temporal sequences in social events, is consistently and robustly activated when we predict future action sequences based on personality traits (Haihambo Haihambo et al. Social Cognitive and Affective Neuroscience 17(2), 241-251, 2022) and intentions (Haihambo et al. Cognitive, Affective, and Behavioral Neuroscience 23(2), 323-339, 2023). In the current study, we investigated whether these cerebellar areas are selectively activated when we predict the sequences of (inter)actions based on protagonists' preferences. For the first time, we also compared predictions based on person-to-person interactions or single person activities. Participants were instructed to predict actions of one single or two interactive protagonists by selecting them and putting them in the correct chronological order after being informed about one of the protagonists' preferences. These conditions were contrasted against nonsocial (involving objects) and nonsequencing (prediction without generating a sequence) control conditions. Results showed that the posterior cerebellar Crus 1, Crus 2, and lobule IX, alongside the temporoparietal junction and dorsal medial prefrontal cortex were more robustly activated when predicting sequences of behavior of two interactive protagonists, compared to one single protagonist and nonsocial objects. Sequence predictions based on one single protagonist recruited lobule IX activation in the cerebellum and more ventral areas of the medial prefrontal cortex compared to a nonsocial object. These cerebellar activations were not found when making predictions without sequences. Together, these findings suggest that cerebellar mentalizing areas are involved in social mentalizing processes which require temporal sequencing, especially when they involve social interactions, rather than behaviors of single persons.

Clique Hierarchy Moderates the Association between Social Preference and Defending Behaviors in Early Adolescence: The Role of Gender Differences.

Although social preference promotes adolescents' defending behaviors, its potential mechanisms across gender cliques remain unclear from the group dynamic perspective. This study investigated 2470 Chinese early adolescents (49% girls, Mage = 14.40, SD = 0.58) to explore how social preference and clique hierarchy are associated with defending behaviors and whether these associations differ across gender-specific cliques. The results revealed that social preference was positively related to defending behaviors in boys' cliques, but negatively in girls' cliques. Furthermore, the association was strengthened by hierarchization in boys' cliques but was weakened in girls' cliques, while the status structure strengthened the association in boys' but not girls' cliques. These findings hold crucial implications for understanding and promoting defending behaviors among adolescents.

Social preferences trump emotions in human responses to unfair offers.

People commonly reject unfair offers even if this leaves them worse off. Some explain this as a rational response based on social preferences. Others argue that emotions override self-interest in the determination of rejection behavior. We conducted an experiment in which we measured responders' biophysical reactions (EEG and EMG) to fair and unfair offers. We measured biophysical trait anger using resting-state EEG (frontal alpha-asymmetry), state anger using facial expressions, offer expectancy processing using event-related EEG (medial-frontal negativity; MFN) and self-reported emotions. We systematically varied whether rejections led proposers to lose their share (Ultimatum Game; UG) or not (Impunity Game; IG). Results favor preference-based accounts: Impunity minimizes rejection despite increasing subjectively reported anger. Unfair offers evoke frowning responses, but frowning does not predict rejection. Prosocial responders reject unfair UG offers more often after unmet fairness expectations. These results suggest that responders do not reject unfairness out of anger. Rather, people seem motivated to reject unfair offers when they violate their behavioral code but only when rejection has payoff consequences for the proposer, allowing them to reciprocate and restore equity. Thus, social preferences trump emotions when responding to unfair offers.

Social preferences in the public goods game-An Agent-Based simulation with EconSim.

Using a reinforcement-learning algorithm, we model an agent-based simulation of a public goods game with endogenous punishment institutions. We propose an outcome-based model of social preferences that determines the agent's utility, contribution, and voting behavior during the learning procedure. Comparing our simulation to experimental evidence, we find that the model can replicate human behavior and we can explain the underlying motives of this behavior. We argue that our approach can be generalized to more complex simulations of human behavior.

Association Between Children's Empathy and Depression: The Moderating Role of Social Preference.

Although empathy is typically an adaptive characteristic of children, extreme empathy alone or in combination with a negative environment may contribute to a risk of depression. The present study comprehensively investigated the associations between the three constructs of empathy and depression in children, as well as the potential moderating effect of peer relationships (i.e., social preference) on this association. A total of 1223 children (mean age = 10.50 ± .93 years) completed questionnaires on empathy and depression, and social preference was nominated by their peers. Cognitive empathy and positive empathy exerted a positive quadratic effect on depression, while negative empathy had a positive linear association with depression. For children with a low social preference, all three empathy constructs were positively quadratically correlated with depression, extremely high and low empathy were associated with increased depression, and moderate empathy was associated with the lowest level of depression. For children with a high social preference, higher positive empathy was associated with lower depression.

Deficiency of Autism-Related Gene Dock4 Leads to Impaired Spatial Memory and Hippocampal Function in Mice at Late Middle Age.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that lasts lifelong and causes noticeably higher premature mortality. Although the core symptoms and other behavioral deficits of ASD can persist or be deteriorated from early development to old age, how aging affects the behaviors and brain anatomy in ASD is largely unknown. DOCK4 is an ASD risk gene highly expressed in the hippocampus, and Dock4 knockout (KO) mice display ASD-like behaviors in adulthood (4- to 6-month-old). In this study, we evaluated the behavioral and hippocampal pathological changes of late-middle-aged (15- to 17-month-old) Dock4 male KO mice. Aged Dock4 KO mice continuously showed similar social deficit, elevated anxiety, and disrupted object location memory as observed in the adulthood, when compared to their wild-type (WT) littermates. Notably, Dock4 KO mice displayed an age-related decline of hippocampal dependent spatial memory, showing decreased spatial memory in Barnes maze than their WT littermates at late middle age. Morphological analysis from WT and Dock4 KO littermates revealed that Dock4 deficiency led to decreased mature neurons and oligodendrocytes but increased astrocytes in the hippocampus of late-middle-aged mice. Together, we report that ASD-like behaviors mostly persist into late-middle age in Dock4 KO mice, with specific alterations of spatial memory and hippocampal anatomy by age, thus providing new evidence for understanding age differences in behavioral deficits of ASD.

The Dispositional Essence of Proactive Social Preferences: The Dark Core of Personality vis-à-vis 58 Traits.

Individuals differ in how they weigh their own utility versus others'. This tendency codefines the dark factor of personality (D), which is conceptualized as the underlying disposition from which all socially and ethically aversive (dark) traits arise as specific, flavored manifestations. We scrutinize this unique theoretical notion by testing, for a broad set of 58 different traits and related constructs, whether any predict how individuals weigh their own versus others' utility in proactive allocation decisions (i.e., social value orientations) beyond D. These traits and constructs range from broad dimensions (e.g., agreeableness), to aversive traits (e.g., sadism) and beliefs (e.g., normlessness), to prosocial tendencies (e.g., compassion). In a large-scale longitudinal study involving the assessment of consequential choices (median N = 2,270; a heterogeneous adult community sample from Germany), results from several hundred latent model comparisons revealed that no meaningful incremental variance was explained beyond D. Thus, D alone is sufficient to represent the social preferences inherent in socially and ethically aversive personality traits.

Vagalumes e biografemas: poéticas e políticas públicas no desligamento institucional por maioridade / Fireflies and biographems: poetics and public policies regarding institutional removal due to adulthood / Luciérnagas y biografemas: poéticas y políticas públicas en desconexión institucional debido a la edad adulta

Este artigo versa sobre o processo de desligamento institucional por maioridade de jovens que residem em serviços de acolhimento. Aposta-se em uma política do sensível para visibilizar os encontros e desencontros que acontecem entre as e os jovens e as políticas públicas brasileiras. Para tanto, realizaram-se encontros com jovens que já haviam passado pelo processo de desligamento e com jovens que logo completariam 18 anos e teriam de sair das instituições de acolhimento. Para tornar visíveis essas existências, investiu-se na escrita de biografemas, inspirados na obra de Roland Barthes. Os conceitos de necropolítica e vidas precárias foram fundamentais para compreender as omissões do Estado no momento do desligamento. Verificou-se que o Estado pode maximizar a precariedade de algumas vidas, especialmente daquelas marcadas por características de raça, gênero e classe culturalmente marginalizados. Contudo, é também o encontro com as políticas públicas que garante melhores condições de vida para alguns, facilitando o acesso à universidade e ao mercado de trabalho. A pesquisa aponta que, diante do abandono, as e os jovens se fazem vagalumes, produzindo luminosidades em meio à escuridão e reivindicando o direito à vida.(AU)

This article discusses the process of institutional removal of young people that reside in foster care institutions for reaching adulthood. It relies on a politics of the sensitive to make visible the encounters and mismatches that take place between young people and Brazilian public policies. To do so, meetings were held with young people who had already experienced the removal process and with young people who would soon turn 18 and would have to leave the host institutions. To make these existences visible, this study invested in the writing of biographems, inspired by the works of Roland Barthes. The concepts of necropolitics and precarious lives were fundamental to understand the omissions of the State at the time of removal. It was also found that the State can maximize the precariousness of some lives, especially those marked by culturally marginalized race, gender, and class characteristics. However, it is also the encounter with public policies that ensures better living conditions for some, facilitating access to the university and the labor market. This research points out that, in the face of abandonment, young people become fireflies, producing luminosity amid the darkness and claiming the right to life.(AU)

Este artículo aborda el proceso de desconexión institucional justificado por la edad adulta de los jóvenes que residen en los servicios de acogida. Utilizamos una política sensible para hacer visibles las reuniones y los desajustes que tienen lugar entre los jóvenes y las políticas públicas brasileñas. Con este fin, se celebraron reuniones con los jóvenes que ya habían pasado por el proceso de desconexión institucional y también con los jóvenes que pronto cumplirían los 18 años y tendrían que abandonar las instituciones de acogida. Para hacer visibles estas existencias, se redactaron biografemas, inspirados en el trabajo de Roland Barthes. Los conceptos de necropolítica y vida precaria fueron fundamentales para comprender las omisiones del Estado en el momento de la desconexión. Se encontró que el Estado puede maximizar la precariedad de algunas vidas, principalmente de aquellas marcadas por características de raza, género y clase culturalmente marginadas. Sin embargo, el encuentro con las políticas también puede garantizar mejores condiciones de vida para algunos, facilitándoles el acceso a la universidad y al mercado laboral. Esta investigación señala que, ante el abandono, los jóvenes se convierten en luciérnagas, produciendo luminosidad en medio de la oscuridad y reclamando el derecho a la vida.(AU)

Resolução de conflitos familiares por adolescentes e defesa do domínio pessoal / Adolescents' family conflict resolution and defense of personal domain / Resolución de conflictos familiares por adolescentes y defensa del dominio personal

Compreender as estratégias de resolução de conflitos utilizadas por adolescentes na relação com seus pais é fundamental para entender como ocorre seu desenvolvimento saudável. Este artigo investigou a resolução de conflitos de adolescentes em situações de confronto entre o seu domínio pessoal e o controle parental. 36 adolescentes com idades entre 15 e 17 anos, divididos igualmente conforme o sexo, responderam a uma entrevista semiestruturada, que continha quatro situações de conflito hipotéticas. Os dados foram submetidos à análise de conteúdo semântica e a testes não paramétricos. Os resultados foram categorizados em sete estratégias: Assunção de culpa, Submissão, Mentira, Hostilidade, Diálogo/Explicação, Negociação e Outra. A forma predominante de resolução utilizada foi o Diálogo/Explicação, considerada como uma forma recorrente de defender o domínio pessoal. Foram encontradas diferenças em relação ao sexo dos participantes e à situação hipotética. Por fim, os resultados são discutidos em termos de grau de autonomia e tipo de defesa do domínio pessoal.(AU)

Understanding the conflict resolution strategies used by adolescents in their relationship with their parents is fundamental to understanding how their healthy development occurs. This article investigated the resolution of conflicts by adolescents in confrontation situations between their personal domain and parental control. A total of 36 adolescents, aged 15 to 17 years, divided equally according to sex, answered a semi-structured interview that contained four hypothetical conflict situations. Data were subjected to semantic content analysis and non-parametric tests. The results were categorized into seven strategies: Assumption of Guilt, Submission, Lie, Hostility, Dialogue/Explanation, Negotiation, and Other. The predominant form of resolution used was Dialogue/Explanation, considered a recurrent form of defense of the personal domain. Differences were found depending on the participants' gender and the hypothetical situation. Finally, the results are discussed regarding the degree of autonomy and type of defense of the personal domain.(AU)

A Call for Drug Therapies for the Treatment of Social Behavior Disorders in Dementia: Systematic Review of Evidence and State of the Art.

Growing evidence supports the presence of social cognition deficits and social behavior alterations in major and minor neurocognitive disorders (NCDs). Even though the ability to identify socio-emotional changes has significantly improved in recent years, there is still no specific treatment available. Thus, we explored evidence of drug therapies targeting social cognition alterations in NCDs. Papers were selected according to PRISMA guidelines by searching on the PubMed and Scopus databases. Only papers reporting information on pharmacological interventions for the treatment of social cognition and/or social behavioral changes in major and/or minor NCDs were included. Among the 171 articles entered in the paper selection, only 9 papers were eligible for the scope of the review. Trials testing pharmacological treatments for socio-emotional alterations in NCDs are poor and of low-medium quality. A few attempts with neuroprotective, psychoactive, or immunomodulating drugs have been made. Oxytocin is the only drug specifically targeting the social brain that has been tested with promising results in frontotemporal dementia. Its beneficial effects in long-term use have yet to be evaluated. No recommendation can currently be provided. There is a long way to go to identify and test effective targets to treat social cognition changes in NCDs for the ultimate benefit of patients and caregivers.

Long-lasting effects of incentives and social preference: A public goods experiment.

This paper addresses the question of the effectiveness and permanence of temporary incentives to contribute to a public good. Using a common experimental framework, we investigate the effects of a recommendation that takes the form of an exhortative message to contribute, a monetary punishment and a non-monetary reward to sustain high levels of contributions. In particular, we shed light on the differential impact these mechanisms have on heterogeneous types of agents. The results show that all three incentives increase contributions compared to a pre-phase where there is no incentive. Monetary sanctions lead to the highest contributions, but a sudden drop in contributions is observed once the incentive to punish is removed. On the contrary, Recommendation leads to the lowest contributions but maintains a long-lasting impact in the Post-policy phase. In particular, it makes free-riders increase their contribution over time in the post-incentive phase. Finally, non-monetary reward backfires against those who are weakly conditional cooperators. Our findings emphasize the importance of designing and maintaining incentives not only for free-riders, but for strong and weak conditional cooperators as well, depending on characteristics of the incentives.

Prefrontal circuits guiding social preference: Implications in autism spectrum disorder.

Although Autism Spectrum Disorder (ASD) is increasing in diagnostic prevalence, treatment options are inadequate largely due to limited understanding of ASD's underlying neural mechanisms. Contributing to difficulties in treatment development is the vast heterogeneity of ASD, from physiological causes to clinical presentations. Recent studies suggest that distinct genetic and neurological alterations may converge onto similar underlying neural circuits. Therefore, an improved understanding of neural circuit-level dysfunction in ASD may be a more productive path to developing broader treatments that are effective across a greater spectrum of ASD. Given the social preference behavioral deficits commonly seen in ASD, dysfunction in circuits mediating social preference may contribute to the atypical development of social cognition. We discuss some of the animal models used to study ASD and examine the function and effects of dysregulation of the social preference circuits, notably the medial prefrontal cortex-amygdala and the medial prefrontal cortex-nucleus accumbens circuits, in these animal models. Using the common circuits underlying similar behavioral disruptions of social preference behaviors as an example, we highlight the importance of identifying disruption in convergent circuits to improve the translational success of animal model research for ASD treatment development.

Belief in conspiracy theories and non-normative behavior.

There are many examples of people believing in conspiracy theories showing non-normative behaviors. But why is this the case? The current contribution proposes that the non-normative behavior of people believing in conspiracy theories is a natural consequence of a different social reality that is associated with the belief in conspiracy theories. This social reality is characterized by a tendency for distinction and distrust in social relationships, a different perception of descriptive norms, a questioning of the injunctive norms regarding specific behaviors, lower trust in institutions and traditional authorities, as well as alternative norms among people believing in conspiracy theories.

Pattern decorrelation in the mouse medial prefrontal cortex enables social preference and requires MeCP2.

Sociability is crucial for survival, whereas social avoidance is a feature of disorders such as Rett syndrome, which is caused by loss-of-function mutations in MECP2. To understand how a preference for social interactions is encoded, we used in vivo calcium imaging to compare medial prefrontal cortex (mPFC) activity in female wild-type and Mecp2-heterozygous mice during three-chamber tests. We found that mPFC pyramidal neurons in Mecp2-deficient mice are hypo-responsive to both social and nonsocial stimuli. Hypothesizing that this limited dynamic range restricts the circuit's ability to disambiguate coactivity patterns for different stimuli, we suppressed the mPFC in wild-type mice and found that this eliminated both pattern decorrelation and social preference. Conversely, stimulating the mPFC in MeCP2-deficient mice restored social preference, but only if it was sufficient to restore pattern decorrelation. A loss of social preference could thus indicate impaired pattern decorrelation rather than true social avoidance.

Acetic acid-induced nociception modulates sociability in adult zebrafish: Influence on shoaling behavior in heterogeneous groups and social preference.

Due to the recognition of fishes as sentient beings, the zebrafish (Danio rerio) has become an emergent animal model system to investigate the biological processes of nocifensive responses. Here, we aimed to characterize the zebrafish social behavior in a nociception-based context. For this purpose, using a three-dimensional analysis of heterogeneous shoals, we investigated the main behavioral responses in two 6-min trials: before (baseline) and after a single intraperitoneal (i.p) injection of 10 µL phosphate-buffered saline (PBS) (control), acetic acid 5% (AA), morphine 2.5 mg/kg (MOR) or acetic acid 5% plus morphine 2.5 mg/kg (AA + MOR) in one subject from a four-fish shoal. The social preference of individuals for tanks with shoals of fish treated with PBS, 5 % AA, or to an empty aquarium was also tested. We verified that AA administration disrupted the shoal homogeneity by eliciting dispersion of the treated fish with simultaneous clustering of non-manipulated fish. In general, morphine coadministration protected against AA-induced behavioral changes. The social preference test revealed a clear preference to conspecifics (PBS and AA) over an empty tank. However, a prominent preference for PBS- over AA-treated shoal was verified. Overall, our novel findings show that nociception can modulate zebrafish sociability, possibly due to the visual recognition of nocifensive responses. Although future studies are needed to elucidate how nociception modulates zebrafish social behavior, our results contribute to improve the welfare assessment of zebrafish shoals under distinct experimental manipulations.

Social preferences for adopting new vaccines in the national immunization program: A discrete choice experiment.

Governments regularly have to decide whether new vaccines should be adopted in their national immunization program. These choices imply complex trade-offs of epidemiological, medical and socio-economic criteria. We investigated how the population in Flanders (Belgium) wants their government to set vaccine-funding priorities. In December 2019, we executed a discrete choice experiment in a sample of the Flemish population (N = 1636). In total, we analysed 16 360 choices between vaccines competing for funding, described in terms of eight characteristics. Using a panel mixed logit model, we quantified the relative importance of each characteristic and investigated differences in preferences across respondent groups. The observed vaccine priorities were different from those that would be identified through cost-effectiveness analysis. People valued the health impact from infectious diseases differently than their weight expressed in QALYs would suggest. Mortality and frequently occurring mild illness were valued higher, whereas lasting morbidity received lower weight. Contribution of the vaccine to disease eradication and uncertainty in vaccine effectiveness were both highly influential factors. Health equity impact was also important whereas the economic impact of the disease did not matter at all. Our results can be used to incorporate public values into vaccine decision-making.
