Cognitive Empathy in Subtypes of Antisocial Individuals

Cognitive and affective perspective taking amongst adolescent offenders with variants of callous-unemotional traits

Evidence suggests that associations between antisocial behaviour, callous-unemotional (CU) traits and cognitive empathy (e.g. perspective taking) vary depending on more fine-grained dimensions of these constructs. This study examined associations between adolescent antisocial behaviour and individual differences in cognitive and affective perspective taking ability. Based on current theory regarding distinct variants of CU traits, we further tested whether the correlates of CU traits differed amongst youth with high versus low levels of anxiety. Participants were 130 male adolescents (81 youth offenders; 49 non-offenders) aged 13-20 years, of predominantly Caucasian and Aboriginal Australian ethnicity. Perspective taking skills were indexed using performance-based testing, and self-report data was collected on CU traits and anxiety in a cross-sectional design. Offender status was associated with poorer cognitive and affective perspective taking. In addition, associations between CU traits and perspective taking skills were moderated by anxiety. Specifically, CU traits were associated with poorer skills for second-order cognitive perspective taking amongst high-anxiety youth, whereas CU traits were associated with better cognitive and affective perspective taking skills amongst low-anxiety youth. More fine-grained assessment of such factors stands to enhance understanding of, and effective intervention for, antisocial youth.

Entactogen Effects of Ketamine: A Reverse-Translational Study

OBJECTIVE

The authors sought to assess the prosocial, entactogen effects of ketamine.

METHODS

Pleasure from social situations was assessed in a sample of participants with treatment-resistant depression from randomized, double-blind, placebo-controlled studies, using four items of the Snaith-Hamilton Pleasure Scale (SHAPS) at five time points over 1 week following treatment with ketamine (0.5 mg/kg intravenously) or placebo. The primary endpoint was postinfusion self-reported pleasure on the four SHAPS items pertaining to social situations, including the item on helping others, between the ketamine and placebo groups. In a rodent experiment, the impact of ketamine on helping behavior in rats was assessed using the harm aversion task. The primary endpoint was a reduction in lever response rate relative to baseline, which indicated the willingness of rats to forgo obtaining sucrose to help protect their cage mate from electric shock.

RESULTS

Relative to placebo, ketamine increased ratings of feeling pleasure from being with family or close friends, seeing other people's smiling faces, helping others, and receiving praise, for 1 week following treatment. In the rodent experiment, during the harm aversion task, ketamine-treated rats maintained lower response rates relative to baseline to a greater extent than what was observed in vehicle-treated rats for 6 days posttreatment and delivered fewer shocks overall.

CONCLUSIONS

In patients with treatment-resistant depression, ketamine treatment was associated with increased pleasure from social situations, such as feeling pleasure from helping others. Ketamine-treated rats were more likely to protect their cage mate from harm, at the cost of obtaining sucrose. These findings suggest that ketamine has entactogen effects.

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.

An 'embedded brain' approach to understanding antisocial behaviour

Antisocial behaviour (ASB) incurs substantial costs to the individual and society. Cognitive neuroscience has the potential to shed light on developmental risk for ASB, but it cannot achieve this potential in an 'essentialist' framework that focuses on the brain and cognition isolated from the environment. Here, we present the case for studying the social transactional and iterative unfolding of brain and cognitive development in a relational context. This approach, which we call the study of the 'embedded brain', is needed to fully understand how risk for ASB arises during development. Concentrated efforts are required to develop and unify methods to achieve this approach and reap the benefits for improved prevention and intervention of ASB.

The protective effects of cognitive empathy and emotional empathy on gambling disorder are mediated by risk aversion and responsible gambling attitude

BACKGROUND

Based on social cognitive theory, this study aimed to examine whether and how social abilities (i.e., cognitive empathy and emotional empathy) are associated with gambling disorder (GD) by incorporating attitudes toward general risk (i.e., risk aversion) and responsible gambling as potential mediators of this link.

METHODS

A convenience sample of 580 past-year lottery gamblers (Mage = 34.07, SD = 13.36; 50.4% female), recruited near lottery sales shops, completed an anonymous paper-version questionnaire on site. Data were collected using the DSM-5 diagnostic criteria for GD, Interpersonal Reactivity Index, Risk Aversion Scale, Positive Play Scale, and demographic items. Path analysis and mediation analysis were applied to examine the effects of cognitive empathy and emotional empathy on GD and the mediating roles of risk aversion and responsible gambling attitude.

RESULTS

Our results showed that cognitive empathy, but not emotional empathy, was significantly and negatively correlated with GD. Also, the effect of cognitive empathy on GD was fully mediated by risk aversion and responsible gambling attitude, whilst the total indirect effect of emotional empathy on GD was nonsignificant. As hypothesized, the indirect paths from both types of empathy to GD were significantly and serially mediated by risk aversion and responsible gambling attitude.

CONCLUSION

Cognitive empathy, distinct from emotional empathy, was a statistically significant correlate of GD. Moreover, the path model results also suggest that responsible gambling attitude was a salient protective factors against GD. Future GD prevention efforts may benefit from paying more attention to the role of responsible gambling attitude.

Empathy and Violence in Schizophrenia and Antisocial Personality Disorder

A paucity of cognitive and affective features of empathy can be correlated with violent behavior. We aimed to identify differences in empathy among four groups in a sample of 100 male participants: (1) 27 violent offenders with schizophrenia, (2) 23 nonviolent patients with schizophrenia, (3) 25 patients with antisocial personality disorder, and (4) 25 subjects from the general population, who formed the control group. Schizophrenia symptoms were quantified with the Positive and Negative Syndrome Scale. Empathy was measured with the empathy quotient. Theory of mind was evaluated using (a) the first-order false-belief task, (b) the hinting task, (c) the faux pas recognition test and (d) the "reading the mind in the eyes" test (revised). Differences noted among the groups were age (controls were younger) and educational status (antisocials were less educated). The empathy quotient scoring (p < 0.001) and theory-of-mind tests (p < 0.001) were distinct between the control group and the three other groups of participants, but not among the three patient groups. Patients with antisocial personality disorder, violent psychotic offenders and psychotic nonviolent patients show no remarkable differences in affective or cognitive empathy tests, but they all present deficits in empathy and theory of mind when compared to controls.

Contrasting social knowledge and theory of mind patterns in adults with personality disorders, schizophrenia spectrum disorders, and healthy controls

INTRODUCTION

Personality disorders (PD) and schizophrenia spectrum disorders (SSD) are distinct conditions displaying common symptoms, like impairments in social cognition, that make them hard to distinguish, especially in severe cases. To date, few studies have compared theory of mind skills in these two disorders, and none have compared social knowledge skills. This study aims to compare the social cognitive abilities of patients with these conditions.

METHOD

Non-parametric analyses of covariance were used to compare severe PD patients (n = 37), SSD patients (n = 44), and healthy controls (HC; n = 49) on the Social Knowledge Test and two measures of theory of mind: the Reading the Mind in the Eyes Test and the Combined Stories Test, which incorporates items from various widely used tests.

RESULTS

While no significant group differences were found on the Social Knowledge Test, SSD patients performed lower than the HC group on both theory of mind tests. PD patients only had lower performance than the HC group on specific items from the Combined Stories Test.

CONCLUSIONS

PD and SSD patients demonstrated distinctive patterns of social cognitive impairments, with items of greater complexity or with an affective orientation being the most discriminant for PD.

Antisocial behavior is associated with reduced frontoparietal network efficiency in youth

Youth antisocial behavior (AB) is associated with deficits in socioemotional processing, reward and threat processing and executive functioning. These deficits are thought to emerge from differences in neural structure, functioning and connectivity, particularly within the default, salience and frontoparietal networks. However, the relationship between AB and the organization of these networks remains unclear. To address this gap, the current study applied unweighted, undirected graph analyses to resting-state functional magnetic resonance imaging data in a cohort of 161 adolescents (95 female) enriched for exposure to poverty, a risk factor for AB. As prior work indicates that callous-unemotional (CU) traits may moderate the neurocognitive profile of youth AB, we examined CU traits as a moderator. Using multi-informant latent factors, AB was found to be associated with less efficient frontoparietal network topology, a network associated with executive functioning. However, this effect was limited to youth at low or mean levels of CU traits, indicating that these neural differences were specific to those high on AB but not CU traits. Neither AB, CU traits nor their interaction was significantly related to default or salience network topologies. Results suggest that AB, specifically, may be linked with shifts in the architecture of the frontoparietal network.

Empathy deficit in male patients with schizophrenia and its relationships with impulsivity and premeditated violence

Objective

To explore the pattern of empathy characteristics in male patients with schizophrenia (SCH) and to examine whether empathy deficit is associated with impulsivity and premeditated violence.

Methods

One hundred and fourteen male SCH patients were enrolled in this study. The demographic data of all patients were collected and the subjects were divided into two groups, namely, the violent group, including 60 cases, and the non-violent group, comprising 54 cases, according to the Modified Overt Aggression Scale (MOAS). The Chinese version of the Interpersonal Reactivity Index-C (IRI-C) was used to evaluate empathy and the Impulsive/Predicted Aggression Scales (IPAS) was employed to assess the characteristics of aggression.

Results

Among the 60 patients in the violent group, 44 patients had impulsive aggression (IA) and 16 patients had premeditated aggression (PM) according to the IPAS scale. In the violent group, the scores of the four subfactors of the IRI-C, i.e., perspective taking (PT), fantasy (FS), personal distress (PD), and empathy concern (EC), were significantly lower than in the non-violent group. Stepwise logistic regression showed that PM was independent influencing factor for violent behaviors in SCH patients. Correlation analysis revealed that EC of affective empathy was positively correlated with PM but not with IA.

Conclusion

SCH patients with violent behavior had more extensive empathy deficits compared with non-violent SCH patients. EC, IA and PM are independent risk factors of violence in SCH patients. Empathy concern is an important index to predict PM in male patients with SCH.

Pathways to antisocial behavior: a framework to improve diagnostics and tailor therapeutic interventions

The Antisocial Personality Disorder (ASPD), and antisocial behavior (ASB) in general, is associated with significant impact on individuals themselves, their environment, and society. Although various interventions show promising results, no evidence-based treatments are available for individuals with ASPD. Therefore, making informed choices about which treatment can be applied to an individual patient is complicated. Furthermore, contradictory findings on therapy effectiveness and underlying factors of ASB, such as cognitive impairments and personality traits, fuel the debate whether the conceptualization of ASPD in the DSM-5 is accurate and whether this population can be seen as homogeneous. A conceptual framework, based on the reciprocal altruism theory, is presented in which we propose different pathways to ASB. These pathways suggest underlying dynamics of ASB and provide an explanation for previous contradictory research outcomes. This framework is intended to serve as a clinically relevant model that provides directions for improving diagnostics and matching treatments to underlying dynamics in the antisocial population.
