Adults' emotional reactions to the pain and pleasure of others are influenced by the moral character of those individuals. However, it remains unclear whether children's emotional responses also show such selectivity. To investigate this, we compared 4- to 8-year-old children's emotional responses to the physical pain and pleasure of prosocial versus antisocial puppets. In Study 1, children reported unhappiness after witnessing the pain of the prosocial and antisocial puppets but reported less unhappiness after witnessing the pain of the antisocial puppet. In Study 2, children reported happiness after witnessing the pleasure of both puppets but reported being less happy for the antisocial puppet. These results suggest that children are less likely to empathize with antisocial individuals. Meanwhile, children did not display Schadenfreude (pleasure at others' pain) or Gluckschmerz (displeasure at others' pleasure) toward antisocial individuals in our studies. Moreover, the selectivity of children's emotional responses disappeared after we manipulated the physical competence rather than the moral character of the puppets in Study 3. Our findings help to reveal the moral selectivity of emotional responses to others' pleasure and pain during early childhood.

Although the development of prosocial behavior has been widely studied from the behavioral aspect, the neural mechanisms underlying prosocial behavior in the early stages of development remain unclear. Therefore, this study investigated the neural mechanisms underlying the emergence of prosocial behavior in 3-year-old children. Brain activity in the medial pFC and right TPJ (rTPJ) and facial expression activity, which are related to the ability to infer others' mental states (mentalizing), during the observation of prosocial and antisocial scenes were measured using functional near-infrared spectroscopy and electromyography, respectively. Subsequently, the children's helping and comforting behaviors toward an experimenter were assessed to examine prosocial behavioral tendencies. A correlation analysis revealed that the children who showed stronger activity levels in the rTPJ while observing prosocial scenes had more immediate helping behaviors toward others than those who did not show stronger response levels. Moreover, the amount of facial expression activity correlated with prosocial behavior, including both helping and comforting behaviors. These results suggest that the development of mentalizing ability and the social evaluation of others' actions, mediated by the rTPJ, contributes to the emergence of prosocial behavior.

Patterns of association with externalizing and internalizing features differ across heroin use and prescription opioid misuse (POM). The present study examined whether heroin use and POM display differential etiologic overlap with symptoms of conduct disorder (CD), adult antisocial behavior (AAB), and major depressive episodes (MDEs), how aggregating heroin use and POM into a single phenotype may bias results, and explored potential sex differences. Seven thousand one hundred and sixty-four individual twins from the Australian Twin Registry (ATR; 59.81% female; = 30.58 years) reported lifetime heroin use, POM, CD symptoms, AABs, and MDE symptoms within a semi-structured interview. Biometric models decomposed phenotypic variance and covariance into additive genetic, common environmental, and unique environmental effects. The proportion of variance in heroin use attributable to factors shared with CD, AAB, and MDE, respectively, was 41%, 41%, and 0% for men and 26%, 19%, and 42% for women; for POM, the proportions were 33%, 35%, and 20% for men and 15%, 9%, and 13% for women. CD and AAB were more strongly genetically correlated with heroin use among women and with POM among men. MDE was more strongly genetically correlated with POM than with heroin use among men, but more strongly genetically correlated with heroin use than with POM among women. Analyses using an aggregate opioid (mis)use variable were biased toward POM, which was the more prevalent phenotype. Magnitude and source of etiologic influence may differ across forms of opioid (mis)use and sex. Disaggregating heroin use and POM in future opioid research may be warranted.

Social support is vital for mental and physical health and is linked to lower rates of disease and early mortality. Conversely, anti-social behavior can increase mortality risks, both for the initiator and target of the behavior. Chronic stress, which also can increase mortality, may serve as an important link between social behavior and healthy lifespan. There is a growing body of literature in both humans, and model organisms, that chronic social stress can result in more rapid telomere shortening, a measure of biological aging. Here we examine the role of anti-social behavior and social support on physiological markers of stress and aging in the social Japanese quail, . Birds were maintained in groups for their entire lifespan, and longitudinal measures of antisocial behavior (aggressive agonistic behavior), social support (affiliative behavior), baseline corticosterone, change in telomere length, and lifespan were measured. We found quail in affiliative relationships both committed less and were the targets of less aggression compared to birds who were not in these relationships. In addition, birds displaying affiliative behavior had longer telomeres, and longer lifespans. Our work suggests a novel pathway by which social support may buffer against damage at the cellular level resulting in telomere protection and subsequent longer lifespans.

BACKGROUND
Callous-unemotional traits are associated with the development of severe behavior problems, delinquency, and psychopathy. Previous studies have repeatedly shown that CU traits may be present as early as preschool age, and they have consistently used the Inventory of Callous-Unemotional Traits (ICU) to assess CU traits in children and adolescents. A three-factor structure for the ICU has been widely endorsed.
METHOD
The aim of our study is to compare the three-factor structure of the ICU in different age groups (preschool, middle childhood, early, and late adolescence) and to test for measurement invariance in a German sample of N = 2368 children and adolescents (M = 11.76 years; SD = 3.72).
RESULTS
The results of our study indicate configural measurement invariance, suggesting that the ICU has the same structure in all age groups but with different meanings, parameters, and mean values in the groups.
CONCLUSION
Accordingly, the ICU cannot be applied in the same way to children and adolescents of different age groups, which emphasizes the need for a more differentiated assessment.

Cascading Effects of the Family Check-Up on Mothers' and Fathers' Observed and Self-Reported Parenting and Young Adult Antisocial Behavior: a 12-Year Longitudinal Intervention Trial.
Over a 12-year period, this study examined the effects of the Family Check-Up preventive intervention model on both observed and self-reported parenting behaviors of mothers and fathers as well as how those parenting behaviors were associated with young adult antisocial behavior. Teachers identified 641 early adolescent youth from school settings to be at elevated risk for the development of externalizing behavior and/or substance use. These youth and their families were randomly assigned to the Family Check-Up intervention model (consisting of an adaptive, multi-tiered model of support, including a school-based family resource room, the Family Check-Up, and targeted follow-up services) or a control condition. Using an intent-to-treat approach, the Family Check-Up intervention model positively impacted mothers' observed parenting approximately 5 years later in middle adolescence but was not associated with changes in fathers' observed or self-reported parenting. Mothers' observed adaptive parenting and fathers' self-reported adaptive parenting in middle adolescence were associated with lower risk for young adult antisocial behavior. The cascading effects of brief, family-focused interventions are discussed along with implications for the measurement of parenting in mothers and fathers in the context of preventive intervention trials.

There is an ongoing debate about anxiety deficits in psychopathy and their possible impact on individual behavior. Data on actual anxiety- and threat-related behavior associated with psychopathy is still limited. We performed a mixed reality study using the elevated plus-maze (EPM) in a non-clinical sample (N = 160) to test anxiety-related behavior in relation to psychopathic personality traits measured through the Brief Questionnaire of Psychopathic Personality Traits (FPP). The psychopathy sum score correlated significantly with all measures of anxiety-related behavior on the EPM. Sensation seeking, but not general levels of acrophobia was moreover associated with psychopathic traits. Multivariate analyses revealed that the subscales Fearlessness and Lack of Empathy of the FPP predicted anxious behavior. Our findings are the first to demonstrate the relationship between psychopathic traits and actual behavior in an anxiety-inducing environment. This supports the low-anxiety hypothesis in psychopathy research. Implications for potentially harmful or risky behavior are discussed.

Research into relationships between victim-generated content, abuse received, and observer characteristics when considering Twitter abuse has been limited to male victims. We evaluated participant perceptions of female celebrity victims and abuse received on Twitter. We used a 3 (Initial Tweet Valence; negative, neutral, positive) × 2 (Abuse Volume; low, high) repeated measures design and online survey method. Participants were shown tweets generated by six female celebrities, counterbalanced such that each participant saw each celebrity in one Valence-Volume condition. Stimuli were presented across six 'lists' such that celebrity 'victims' could be rotated across Valence-Volume pairings. Participants rated-per target stimulus-the level of blame attributable to the victim and the perceived severity of the incident. Furthermore, participants were asked to complete a Dark Tetrad scale-measuring their Machiavellianism, Narcissism, Psychopathy, and Sadism. Analyses determined that victim-blaming was influenced by victim Initial Tweet Valence (greater victim-blaming associated with more-negative content) and observer Machiavellianism. Perceived severity was influenced by victim Initial Tweet Valence, Volume of Abuse received, and observer Machiavellianism. Results were consistent with previous research involving male celebrity victims. Further research is needed to understand the contributions of participants' hostile and benevolent sexism, as well as the role of victim attractiveness.

Dysregulation of Plasma Growth Factors and Chemokines in Cocaine Use Disorder: Implications for Dual Diagnosis with Schizophrenia and Antisocial Personality Disorder in an Exploratory Study.
INTRODUCTION
Dual diagnosis in individuals with cocaine use disorders (CUDs) presents a mental health challenge marked by an increased susceptibility to disabling morbidities and premature mortality. Despite extensive research on depression and anxiety, other prevalent comorbidities, such as psychotic and personality disorders, have received less attention. This study explores inflammation-related mediators as potential biomarkers for CUD and dual diagnosis with schizophrenia (SCZ) or antisocial personality disorder (APD).
METHODS
This exploratory study included 95 participants, comprising 40 healthy subjects and 55 abstinent patients with CUD. Lifetime CUD was diagnosed either as single diagnosis (CUD group, N = 25) or as a dual diagnosis (DD group. N = 30) with SCZ (CUD+SCZ subgroup) or APD (CUD+APD subgroup). Participants were clinically assessed, and the plasma concentrations of growth factors (i.e., G-CSF, BDNF, and VEGF-A) and chemokines (i.e., CCL11/eotaxin-1, CCL2/MCP-1, and CXCL12/SDF-1) were determined and log(10)-transformed for analysis.
RESULTS
Growth factors and chemokines were dysregulated by CUD and psychiatric diagnoses. Specifically, patients in the CUD group exhibited significantly lower concentrations of G-CSF and CCL11/eotaxin-1 than the control group. In contrast, the DD group showed significantly higher concentrations of all analytes than both the CUD and control groups. Additionally, no differences in these analytes were observed between the CUD+SCZ and CUD+APD subgroups within the DD group. Regarding cocaine-related variables, significant associations were identified in the CUD group: an inverse correlation between the age at first cocaine use and the concentrations of BDNF and CCL2/MCP-1; and a positive correlation between the duration of the cocaine abstinence and the concentrations of BDNF and CCL11/eotaxin-1. Lastly, a logistic regression model incorporating all these analytes demonstrated high discriminatory power in distinguishing patients with CUD alone from those with dual diagnosis.
CONCLUSIONS
Individuals with dual diagnosis of CUD exhibit elevated concentrations of growth factors and chemokines, distinguishing them from those with CUD alone. It is unclear whether the differences in these inflammatory mediators are specific to the presence of SCZ and APD. The study highlights potential biomarkers and associations, providing valuable insights into the intricate interplay of CUD and psychiatric disorders to enhance clinical diagnosis and therapeutics.

Pediatric Obesity Jul 2024This study aimed to investigate weight bias within young children's pro-social choices between characters who differed in body size.
OBJECTIVES
This study aimed to investigate weight bias within young children's pro-social choices between characters who differed in body size.
METHODS
Seventy-six children aged 4-6 years read stories asking them to choose who they would first help, share with, comfort, and steal from, between a healthy weight and child with overweight. They also selected the one character they would most like to play with. Children's reasoning for these choices was recorded and analysed.
RESULTS
The character with overweight was helped first in only a third of the choices made. Children chose the characters with overweight more often as the target for anti-social action. In friendship selections, children overwhelmingly rejected the characters with overweight. However, weight bias was not prominent in the reasons children gave for the choices. Most children were not negative about body shape, weight or appearance. Similarly, in friendship choices, these were mostly expressed positively to the character chosen. Only a small minority of children were explicitly negative about the character with overweight.
CONCLUSIONS
A better understanding of weight bias acquisition and variation between children will benefit those working in health care and educational settings. Future research should link with developmental theory, such as on social categorization and theory of mind.
