Aggressive Male Juvenile Offenders with Callous-Unemotional Traits Show Aberrant Attentional Orienting to Distress Cues

Antisocial youth with callous-unemotional (CU) traits exhibit a pattern of severe and persistent conduct problems and deficits in emotional processing that parallels adults with psychopathy. Aberrant emotional attention, particularly among individuals high on aggression, constitutes one such deficit; however, its robustness across race/ethnicity requires further investigation given findings that the psychopathy construct manifests differently across race (Sullivan and Kosson 2006), and emotional attention is susceptible to the influence of adverse environmental factors such as violence exposure that is more common among ethnic minority youth (Kimonis et al. in Development and Psychopathology, 20, 569–589, 2008b). Also, the development of a comprehensive measure of CU traits, the Inventory of Callous-Unemotional Traits (ICU), has identified specific CU dimensions (Uncaring, Callous, Unemotional) that are yet to be investigated in relation to emotional attention deficits. Thus, the purpose of the present study was to examine whether aggressive boys high on total CU traits and specific ICU dimensions show deficits in attentional orienting to negative stimuli on a dot-probe task that are consistent across race/ethnicity. Results from a predominately Latino sample of incarcerated male adolescents (N = 156) showed that aggression moderated the association between CU traits and facilitation to distress stimuli. That is, aggressive boys high on CU traits or the Uncaring dimension showed deficient attentional orienting; a finding that was consistent across racial/ethnic minority groups. Results are consistent with prior research suggesting that the combination of high CU traits and aggression defines a unique subgroup of antisocial individuals that more closely fits with the construct of psychopathy than the presence of CU traits alone.     

The roles of trauma exposure,rejection sensitivity,and callous‐unemotional traits in the aggressive behavior of justice‐involved youth: A moderated mediation model

Research has demonstrated an association between childhood trauma exposure and adolescent aggression. This association may be explained by rejection sensitivity, defined as anger, or anxiety in the anticipation of rejection, which can be a consequence of trauma exposure. Callous‐unemotional (CU) traits also are associated with trauma exposure and aggressive behavior; however, research has not yet investigated the interactive roles that rejection sensitivity and CU traits play in the relation between trauma exposure and aggression. Therefore, this study sought to investigate the role of rejection sensitivity in the association between trauma exposure and aggression, and whether this indirect effect was moderated by CU traits. Participants included 380 detained youth (98 girls, 282 boys) who completed self‐report measures of trauma exposure, angry, and anxious rejection sensitivity, CU traits, and aggression. Results of moderated mediation demonstrated that the relation between trauma exposure and aggression exhibited an indirect effect through angry rejection sensitivity, but only at moderate or high levels of CU traits. This pattern was not found for anxious rejection sensitivity. Results suggest that interventions aimed to decrease aggressive behavior in traumatized adolescents may benefit from considering how youth respond to rejection, as well as whether youth endorse CU traits, as this may help to limit further involvement in the juvenile justice system after release.

     

The Moderating Role of Anxiety in the Associations of Callous-Unemotional Traits with Self-Report and Laboratory Measures of Affective and Cognitive Empathy

In a sample of detained male adolescents (n = 107; Mean age = 15.50; SD = 1.30), we tested whether anxiety moderated the association of CU traits with self-report and computerized measures of affective (emotional reactivity) and cognitive (affective facial recognition and Theory of Mind [ToM]) empathy. Hierarchical regression analyses revealed that CU traits were negatively associated with self-reports of affective empathy and this association was not moderated by level of anxiety. Significant interactions revealed that CU traits were negatively associated with cognitive empathy (self-report) only at high levels of anxiety, whereas CU traits were positively associated with cognitive empathy on the ToM task only at low levels of anxiety. CU traits were also associated with greater fear recognition accuracy at low levels of anxiety. Implications for understanding and treating different variants of CU traits (i.e., primary and secondary) are discussed.     

Startle modulation during violent films: Association with callous–unemotional traits and aggressive behavior

The current study examined the unique and interactive associations of callous–unemotional (CU) traits, impulsive and premeditated aggression with startle modulation to violent films. Eighty-five participants (Mage = 20.52) at differential risk of CU traits, selected from a sample of 1105 young adults, participated in the physiological experiment. Startle eye-blink responses to acoustic probes were recorded during violent, comedy and neutral films. Self-report ratings of valence and arousal were also collected. Findings from regression analysis documented that CU traits were associated with diminished startle potentiation to violent films, whereas impulsive aggression was associated with increases in startle potentiation. Further, the negative association between CU traits with startle potentiation, valence, and arousal ratings to violent films was moderated by impulsive aggression. At the group level, individuals high on impulsive aggression without CU traits were the ones showing the highest levels of startle potentiation to violent films, and scored on the opposite extreme compared to individuals high on both CU traits and impulsive aggression.     

Individual, Social, and Behavioral Factors Associated with Co-Occurring Conduct Problems and Callous-Unemotional Traits

Conduct problems (CP) and callous-unemotional (CU) traits can have a long-lasting negative impact into adulthood. Importantly, among youth with CP, those high on CU traits engage in a more severe, aggressive, and persistent pattern of antisocial behavior. The current study investigates the co-occurrence between CP and CU traits among a large sample of Greek-Cypriot adolescents (N?=?1,674; 50.1 % girls). Five distinct groups were identified with Latent Profile Analysis: low risk (48.7 %), average risk (33.8 %), co-occurring high CP-high CU (5.4 %), high CP-low CU (5.2 %), and low CP-high CU (6.9 %). Although more boys were identified in the higher risk groups, boys and girls within each group were not differentiated on levels of CP or CU traits during early adolescence. Youth in the identified groups were compared on early (Mean age?=?12.12) and middle (Mean age?=?14.02) adolescence individual and contextual factors. Youth with high CP-high CU were at higher risk for behavioral (bullying and substance use), individual (inattention, impulsivity, narcissism), and contextual (low family-support) problems compared to youth in the high CP-low CU and low CP-high CU groups, providing evidence that the combination of CP and CU traits might constitute a pathological group. These findings demonstrate the usefulness of sub-typing CP based on CU traits for the forthcoming fifth edition of the Diagnostic and Statistical Manual. Additional novel findings suggested that adolescents scoring high on CP, irrespective of CU, were not differentiated on hyperactivity, victimization, and anxiety/depression, and adolescents scoring high on CU traits, with or without CP, reported similar low levels of self-esteem and peer and family social-support.     

What do others feel? Cognitive empathy deficits explain the association between callous-unemotional traits and conduct problems among preschool children

Abstract

Callous-unemotional traits (CU) are a risk factor for antisocial behavior, although it is unclear whether deficits in affective or cognitive empathy explain this association. Using a multi-informant approach involving data collection from parents and teachers (N = 167, M age = 4.7 years), the current study aimed to test whether cognitive or affective empathy deficits account for the association between CU traits and antisocial behavior among preschool children. Results revealed that cognitive, but not affective, empathy was associated with both CU and conduct problems, and also mediated the relationship between CU traits and conduct problems. These findings were not replicated for overt and relational aggressive behavior. Our findings suggest that cognitive empathy deficits may be more important than affective empathy in explaining antisocial behavior in preschool children. As a result, interventions aiming to reduce conduct problems early in development may need to target difficulties in understanding what others are thinking or feeling.     

The Role of Intimate Exchange in the Link Between Reactive Aggression and Child Depressive Symptoms

Although the link between reactively aggressive behavior and depressive symptoms in childhood has been demonstrated in previous work, few studies have examined how peer factors may influence this association. Examining the role of peers in the link between reactive aggression and depressive symptoms is necessary, as peers have been found to buffer the impact of factors that contribute to depressive symptoms in childhood. Accordingly, we examined whether intimate exchange with a best friend moderated the association between reactive aggression and depression in childhood in a sample of 115 children (aged 5–14; M = 8.88; 87 % minority; 53 % male) who attended a community based summer program. Consistent with expectation, reactive aggression was positively associated with child depressive symptoms whereas proactive aggression was negatively associated with depressive symptoms. Further, the interaction between intimate exchange and reactive aggression was associated with child depressive symptoms. Specifically, the association between reactive aggression and depressive symptoms was weaker when levels of intimate exchange were high. Thus, the current study suggests that close peer relationships may help to buffer the link between reactively aggressive behavior and depressive symptoms. Implications for findings include the need to target friendships to help prevent depressive symptoms for reactively aggressive youth.     

Trait aggression is related to anger-modulated deficits in response inhibition

The goal of the present study was to investigate the role of emotion-modulated response inhibition in individual difference in the disposition towards aggressive behavior (i.e. trait aggression). One hundred and twelve undergraduate participants completed a behavioral measure of emotion modulated response inhibition (an emotional go/no-go task), self-report measures previously shown to predict aggression (Big-5 traits, impulsivity), and the Aggression Questionnaire (AQ) as a measure of trait aggression. Results show that deficient inhibition to angry, but not happy, faces were related to trait aggression but not to other traits. These findings provide support for the role of specific top down executive control mechanisms in the regulation of aggressive tendencies and highlight the importance of examining these mechanisms in an emotional context.     

内隐/外显不同水平攻击者的注意偏向：行为和ERP证据

通过行为实验（点探测）和ERP实验（情绪Stroop）两个实验任务,考察了内隐/外显不同水平攻击者的注意偏向及其脑机制。结果表明：高外显攻击者对愤怒面孔存在注意偏向;高外显攻击者在愤怒面孔上的N100波幅显著低于中性面孔,表明其注意分配和调节能力较弱;高外显攻击者较之低外显攻击者的P300波幅更小表明其存在注意等方面的认知加工缺陷,N400波幅更小表明其对愤怒面孔进行语义编码时加工更为流畅;外显攻击组与内隐攻击组在FCz和Cz电极点上不同。这为内隐/外显攻击二者有着独立结构提供了行为与认知神经科学的证据。     

Callous-Unemotional Traits Only Versus the Multidimensional Psychopathy Construct as Predictors of Various Antisocial Outcomes During Early Adolescence

The aim of this study was to compare callous-unemotional (CU) traits versus the multidimensional psychopathy construct in their ability to predict future and stable antisocial behavior. At baseline, a community sample of 996 Cypriot 12-year old adolescents (52% girls) completed measures that tap conduct problems (CP) and psychopathic traits, including CU. CP, aggression, and substance use were self-reported at 1–3 year follow-ups. Youths were assigned to six mutually exclusive groups based on their baseline levels of CP and psychopathic traits. Youth with CP scoring high on all three psychopathic traits dimensions (Psychopathic Personality?+?CP) showed the most robust and highest risk for future and stable CP, aggression, and substance use, followed by youth who were high on all three psychopathic traits dimensions but displayed no concurrent CP (Psychopathic Personality Only) and CP youth with low levels of psychopathic traits (CP Only). Youth with CP who merely manifested callous-unemotional traits (Callous-Unemotional?+?CP) were only at risk for future CP. The findings suggest that the CU traits-based approach for subtyping children with CP is less informative compared to a subtyping approach using various psychopathic traits dimensions in predicting future and stable forms of various antisocial outcomes. These findings and their consistency with prior work indicate the need for additional research to examine the various psychopathic traits dimensions rather than focusing solely on CU traits, especially for CP subtyping purposes.     

Low Maternal Warmth Mediates the Relationship Between Emotional Neglect and Callous-Unemotional Traits Among Male Juvenile Offenders

Callous-unemotional traits (CU) are thought to be the developmental precursor to adult psychopathy, and identify antisocial youth at risk for persistent, aggressive conduct problems. Accumulating research supports the importance of parenting factors in the development of CU traits. The overlapping but distinct constructs, parental neglect and low warmth, are both associated with CU/psychopathic traits; however, research is yet to examine the relative contribution of these constructs. The purpose of the present study was to examine the unique contributions of parental neglect and low warmth to CU traits among 227 incarcerated male juvenile offenders (M?=?15.73, SD?=?1.27 years). Results indicated that low levels of maternal warmth were more strongly associated with CU traits than emotional and physical neglect. Maternal warmth also significantly mediated the association between emotional neglect and CU traits. Findings from this cross-sectional study suggest that parental neglect influences CU traits at least partly through experiences with unresponsive and emotionally “cold” parenting. The findings also support a movement within the field towards addressing parental warmth as a treatment target for antisocial youth with CU traits.     

冷酷无情特质：一种易于暴力犯罪的人格倾向

冷酷无情特质(callous unemotional trait, CU)是指对他人冷漠、缺乏罪责感、低共情的一种人格倾向, 伴随有高频率和高破坏性的反社会行为甚至暴力犯罪。CU特质者在情感上表现为对负性情绪加工不敏感, 缺乏共情; 在认知上表现出追求奖赏、忽视惩罚; 在生物学方面, CU特质者生理唤醒水平低、皮质醇水平低、杏仁核和腹内侧前额叶活动异常。未来研究的方向是修订发展本土化CU特质量表、探析CU特质者的性别差异、梳理CU与品行障碍等其他精神障碍的关系、为暴力犯循证矫正的方案设计提供科学依据。     

Distilling Heterogeneity among Children with Disruptive Behavior: Associations between Symptom Patterns and Social Functioning

Children with disruptive behavior (DB) are a heterogeneous group who exhibit several characteristics that may contribute to poor social functioning. The present study identified profiles of reactive aggression, proactive aggression, callous-unemotional (CU) traits, and prosocial behavior in a sample of children with DB. Associations with social functioning (social interaction, social status) were then examined, along with sex differences in profile membership. Parent ratings of 304 clinic-referred children ages 6–12 years with DB were analyzed using latent profile analysis. Five profiles were identified: 1) Moderate prosocial behavior, reactive aggression, and CU, and low proactive aggression (labelled Moderate); 2) Relatively high prosocial behavior and low reactive and proactive aggression and CU traits (Prosocial); 3) High prosocial behavior and reactive aggression, moderate proactive aggression, and low-moderate CU (Reactive-Prosocial); 4) Low prosocial behavior, high CU, high-moderate reactive aggression, and low-moderate proactive aggression (Reactive-CU); and 5) Low prosocial behavior and high reactive and proactive aggression and CU (Aggressive-CU). Profiles characterized by CU traits, reactive aggression, and low prosocial behavior were associated with the most problematic parent-rated social interaction and social status. The results highlight the need to differentiate profiles of psychopathology in children with DB to better address factors most associated with social functioning.     

Effects of long-term meditation practice on attentional biases towards emotional faces: An eye-tracking study

Attentional biases towards affective stimuli reflect an individual balance of appetitive and aversive motivational systems. Vigilance in relation to threatening information reflects emotional imbalance, associated with affective and somatic problems. It is known that meditation practice significantly improves control of attention, which is considered to be a tool for adaptive emotional regulation. In this regard, the main aim of the present study was to evaluate the influence of meditation on attentional bias towards neutral and emotional facial expressions. Eyes were tracked while 21 healthy controls and 23 experienced meditators (all males) viewed displays consisting of four facial expressions (neutral, angry, fearful and happy) for 10 s. Measures of biases in initial orienting and maintenance of attention were assessed. No effects were found for initial orienting biases. Meditators spent significantly less time viewing angry and fearful faces than control subjects. Furthermore, meditators selectively attended to happy faces whereas control subjects showed attentional biases towards both angry and happy faces. In sum we can conclude that long-term meditation practice adaptively affects attentional biases towards motivationally significant stimuli and that these biases reflect positive mood and predominance of appetitive motivation.     

Interactions between Callous Unemotional Behaviors and Executive Function in Early Childhood Predict later Aggression and Lower Peer-liking in Late-childhood

Callous unemotional (CU) behaviors are linked to aggression, behavior problems, and difficulties in peer relationships in children and adolescents. However, few studies have examined whether early childhood CU behaviors predict aggression or peer-rejection during late-childhood or potential moderation of this relationship by executive function. The current study examined whether the interaction of CU behaviors and executive function in early childhood predicted different forms of aggression in late-childhood, including proactive, reactive, and relational aggression, as well as how much children were liked by their peers. Data from cross-informant reports and multiple observational tasks were collected from a high-risk sample (N = 240; female = 118) at ages 3 and 10 years old. Parent reports of CU behaviors at age 3 predicted teacher reports of reactive, proactive, and relational aggression, as well as lower peer-liking at age 10. Moderation analysis showed that specifically at high levels of CU behaviors and low levels of observed executive function, children were reported by teachers as showing greater reactive and proactive aggression, and were less-liked by peers. Findings demonstrate that early childhood CU behaviors and executive function have unique main and interactive effects on both later aggression and lower peer-liking even when taking into account stability in behavior problems over time. By elucidating how CU behaviors and deficits in executive function potentiate each other during early childhood, we can better characterize the emergence of severe and persistent behavior and interpersonal difficulties across development.     

Links between relational aggression,parenting and personality among adolescents

The aim of this cross-sectional study was to examine the mediating role of behavioral inhibition system, referring to the inhibition of behavior, and behavioral activation system (BAS), related to impulsivity, in the association between perceived parenting behaviors and relational aggression. It simultaneously investigated the moderating effects of callous-unemotional (CU) traits in this association in a sample of 261 (127 girls) Greek junior high school students who completed a self-report questionnaire. Results of the mediation analyses revealed that BAS was a partial mediator in the relationship between low parental psychological autonomy and relational aggression, as well as between low parental behavioral control and relational aggression. The effect of low parental psychological autonomy on relationally aggressive behavior was also significantly stronger when CU traits were present (moderator). The results emphasize that both individual and interpersonal factors should be taken into consideration when studying relational aggression.     

Exposure to Violence as a Mediator of the CU–Aggression Relationship: on the Importance of Establishing the Causal Direction of Variables in a Path Analysis

The current study sought to determine which of three variables—callous-unemotional (CU) traits, exposure to violence (ETV), and aggressive offending—did the best job of mediating the other two variables. This question was addressed in a sample of 1170 male delinquents from the Pathways to Desistance study using three waves of data and the comparison pathways approach to mediation. Consistent with predictions, ETV successfully mediated the CU–aggression relationship, whereas the two control pathways (ETV?→?CU?→?aggression and CU?→?aggression → ETV) were non-significant. These results suggest that certain variables are better suited to serving as mediators than other variables. Hence, while personality-based constructs like CU traits perform well as independent variables and behavioral measures like aggressive offending make for effective dependent variables, mediation is perhaps best served by social cognitive, affective-motivational, perceptual, and experiential variables, the latter of which is the category into which exposure to violence falls. From a theoretical standpoint, these findings suggest that exposure to violence may trigger or prime aggressive offending in individuals possessing strong CU traits. Exposure to violence may therefore serve as one mechanism with the capacity to link CU traits to later aggressive offending, with implications for both prevention and intervention.     

Attention-deficit/hyperactivity disorder and callous-unemotional traits as moderators of conduct problems when examining impairment and aggression in elementary school children

Examined whether attention-deficit/hyperactivity disorder (ADHD) and callous-unemotional (CU) traits moderate the association between conduct problems (CPs) and impairment and aggression. Participants were 214 children who were rated by their elementary school classroom teachers. Results indicated that the association between CP and impairment and aggressive outcomes is almost always moderated by ADHD and/or CU. Moreover, in many instances, the association between CP and outcomes was moderated by both ADHD and CU such that the moderating effects of CU on CP were more pronounced at lower levels of ADHD. Results are discussed with respect to developmental taxonomies and trajectories of the disruptive behavior disorders.     

Can a Laboratory Measure of Emotional Processing Enhance the Statistical Prediction of Aggression and Delinquency in Detained Adolescents with Callous-unemotional Traits?

In this cross-sectional study, we investigated whether the combination of the presence of callous-unemotional (CU) traits and emotional deficits to distressing stimuli, assessed by a computerized dot-probe task, enhanced the statistical prediction of aggression and delinquency in a sample of 88 detained and predominantly African-American (68%) adolescents (M age = 15.57; SD = 1.28). Overall, self-reported CU traits were associated with self-report measures of aggression and delinquency, but not with official records of arrests. However, there was an interaction between CU traits and emotional deficits for predicting self-reported aggression, self-reported violent delinquency, and a record of violent arrests. Youth high on CU traits and who showed a deficit in their responses to visual depictions of distress showed the highest levels of aggression and violent delinquency.     

Patterns of Physical and Relational Aggression in a School-Based Sample of Boys and Girls

The current study investigated the patterns of aggressive behavior displayed in a sample of 282 students in the 4th through 7th grades (M age = 11.28; SD = 1.82). Using cluster analyses, two distinct patterns of physical aggression emerged for both boys and girls with one aggressive cluster showing mild levels of reactive aggression and one group showing high levels of both reactive and proactive aggression. Both aggressive clusters showed problems with anger dysregulation, impulsivity, thrill and adventure seeking, positive outcome expectancies for aggression, and higher rates of bullying. However, the combined cluster was most severe on all of these variables and only the combined aggressive group differed from non-aggressive students on their level of callous-unemotional traits. Similar patterns of findings emerged for relational aggression but only for girls.
