Aggression in boys with attention deficit-hyperactivity disorder: Methylphenidate effects on naturalistically observed aggression,response to provocation,and social information processing

High and low-aggressive boys with attention deficit-hyperactivity disorder (ADHD) were compared and the effects of methylphenidate were examined on measures from three domains of aggression: (1) directly observed verbal and nonverbal aggressive behaviors exhibited in the context of a day treatment program, (2) aggressive responding when provoked during a laboratory task, and (3) social information processing patterns exhibited on tasks designed to tap the putative cognitive components of aggression. The high-aggressive (HA) and low-aggressive (LA) subgroups differed significantly on observational measures of aggression and on the laboratory provocation task, but the HA group showed more deviant cognitions on only one of the numerous measures of social information processing. Regarding medication effects on the direct observation measures, methylphenidate decreased aggression for both subgroups. On the laboratory provocation task, methylphenidate had only minimal effects. Significant drug effects were obtained on only two recall social information processing measures.     

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.     

Empathy as a cognitive inhibitor of interpersonal aggression

The studies presented in this paper examined empathy, especially perspective taking, as a potential inhibitor of interpersonal aggression. The theoretical rationale for these investigations derived from Zillmann's [(1988): Aggressive Behavior 14: 51–64] cognitive excitation model. Study 1 revealed that dispositional empathy correlates negatively with self-reported aggression and with conflict responses that reflect little concern for the needs of the other party. Empathy also was positively related to constructive responses to interpersonal conflict (i. e., those that do involve concern for the needs of the other party). In Study 2, perspective taking was manipulated with instructions to subjects prior to participation in a reaction-time task designed to measure aggression. When threat was relatively low, subjects who were instructed to take the perspective of the target responded less aggressively than did those who had been instructed to focus on the task. Study 3 examined the effect of dispositional perspective taking on verbal aggression. Threat was manipulated in terms of the combination of provocation and gender of the interactants. As predicted, perspective taking related to aggression inhibition under conditions of moderate threat–for males under low provocation and females under high provocation. These effects were predicted and explained in the context of the cognitive-excitation model. © 1994 Wiley-Liss, Inc.     

未成年人归因的内隐特征与攻击行为

本研究使用投射法这一内隐社会认知的研究方法,考察了朱成年人罪犯群体与正常群体的攻击行为内隐社会认知过程的特征,结果表明：整体上而言,未成年人罪犯群体与正常群体的内隐归因方式存在显著差异,罪犯的内控程度要低于常人的内控程度。从而得出罪犯产生攻击性犯罪行为的原因之一是他们的归因存在偏差,支持了攻击行为成因的归因模型。未成年人男女两性在内隐的内外控方面不存在显著差异,且结果提示归因方式与女性罪犯的攻击行为没有必然联系。     

Relational aggression in college students: Examining the roles of social anxiety and empathy

This study examined the unique contributions of social anxiety and empathy to relational aggression in 300 19–to–25–year–old (M=21.25; SD=1.32) male (n=97) and female (n=203) college students using hierarchical linear regression analysis. The interactive relations between gender and social anxiety, and between gender and empathy, were also assessed. In addition to the gender and overt aggression covariates, fear of negative evaluation and perspective taking were unique predictors of relational aggression. Males, students who were more overtly aggressive, and those who reported greater fear of negative evaluation were more relationally aggressive than were peers. Students with higher levels of perspective taking reported using less relational aggression than did peers. A gender x empathetic concern interaction indicated that for males only, lower levels of empathetic concern were associated with higher levels of relational aggression. Results are discussed within a social information‐processing perspective. Aggr. Behav. 29:430–439, 2003. © 2003 Wiley‐Liss, Inc.     

暴力电子游戏对攻击行为的影响及其争论

以Anderson为核心的研究者通过数十年研究发现, 暴力电子游戏是攻击行为产生的前因变量, 并且提出可以用一般攻击模型(General Aggression Model, GAM)来解释这一结论。然而, Ferguson等人的研究表明, 暴力电子游戏不是攻击行为产生的前因变量, 而是攻击行为产生的催化剂, 并提出催化剂模型(Catalyst Model, CM)来解释该结论。由于社会心理研究中, 实验研究难以严格控制, 导致研究结果大径相庭, 暴力电子游戏影响攻击行为的争论还在不断扩大。未来要加强对暴力电子游戏和攻击行为的测量, 同时还需整合一般攻击模型和催化剂模型指导实证研究, 最后从认知偏差以及社会认知神经科学视角寻求暴力电子游戏对攻击行为影响的新证据。

运用问卷调查的方法,以424名大学生为研究对象,探讨了观点采择和道德推脱对大学生网络偏差行为的影响。研究发现：（1）大学生的网络偏差行为并不十分严重,但男生的网络偏差行为明显多于女生的网络偏差行为;（2）观点采择会对大学生的网络偏差行为产生显著的负向影响,但这一影响过程需要通过道德推脱的完全中介作用而实现。     

The role of social‐cognitive abilities in preschoolers' aggressive behaviour

This study investigated the relationship between preschool children's social‐cognitive abilities (theory of mind and social information processing; SIP) and their observed physical and relational aggressive behaviour. Children with more advanced social‐cognitive abilities engaged in fewer acts of physical aggression; however, much of the ability of the social‐cognitive variables to predict physical aggression was shared with language ability. In addition, social‐cognitive understanding moderated the connection between language ability and physical aggression. Exploratory examination of gender differences in patterns of association between physical aggression and the social cognitive understanding variables revealed that the relationships were only true for boys. Relational aggression was not associated with social cognitive ability for either boys or girls, but this is likely due to the low frequency of relationally aggressive behaviour observed in this sample.     

Rural adolescent aggression and parental emotional support

Preliminary research findings suggest important distinctions between rural and urban adolescent aggression risk and protective factors. Despite these potentially important differences, most of the existing research on adolescent aggression has utilized urban samples. The current study examines the direct association between parental emotional support and rural adolescent aggression, and whether adolescent psychopathology and substance abuse mediate this association. Multi-method measurement (self-report, parent report, and behavioral observations) were employed in measuring aggression and emotional support variables with rural, nonadjudicated adolescents (N=62) and their mothers or stepmothers. Results indicated that parental emotional support has an indirect influence on adolescent aggression. Adolescent substance abuse was completely mediated by adolescent grade-point average, indicating no significant direct impact on aggression. Adolescent psychopathology significantly mediated the relationship between parental emotional support and adolescent aggression. Particular items contributed substantially to this mediating association, making certain characteristics, rather than a specific diagnosis, relevant to psychopathology's mediating impact. These characteristics include cognitive perception of others as critical or hostile, emotional anxiousness in social situations, and behavioral persistence in social interactions despite these perceptions.     

Embarrassment and empathy before helping: How internal working models come into play

Prior research has described embarrassment and empathy as predictors of social helping and as self-conscious emotions involving reasoning about the self and others. It remains unclear how cognitive representations of the self and others relate to the two emotions as precursors of social helping. We examined 136 participants’ self-report measures of internal working models as well as dispositional embarrassability, empathic concern, personal distress, and perspective taking. Controlling all the other variables, embarrassability was primarily associated with the model of self and personal distress, whereas empathic concern was primarily associated with the model of others and perspective taking. Moreover, the association between personal distress and embarrassability was moderated by the interaction between models of others and perspective taking. The general proneness to distress arousal was also predicted by the interaction between models of self and others. The findings extended prior research linking internal working models and socio-cognitive emotions associated with helping.     

Assessing the role of aggression,empathy, and self‐serving cognitive distortions in trait emotional manipulation

This study extended the examination of the predictors of emotional manipulation. Participants (N = 243) completed measures of trait emotional manipulation, emotional intelligence, social skills, psychopathy, aggression, empathy, and self‐serving cognitive distortions in a cross‐sectional correlational design. For males, higher levels of emotional intelligence, social information processing, indirect aggression, and self‐serving cognitive distortions significantly predicted emotional manipulation. For females, being younger, higher levels of emotional intelligence, indirect aggression, primary psychopathic traits, and lower levels of social awareness significantly predicted emotional manipulation. However for females, emotional intelligence acted as a suppressor. These findings support previous indications that the mechanisms behind emotional manipulation differ as a function of gender. Future research could include ability, rather than trait measures of emotional manipulation, as well as the role of context (such as intimate relationships or workplace environments), thereby allowing additional examination of the nomological network of emotional manipulation.     

Handgrip strength and socially dominant behavior in male adolescents

Handgrip strength (HGS) is highly heritable and a good overall measure of strength and muscle function. Indicative of blood testosterone levels and fat-free body mass, HGS is also highly sexually dimorphic. Recent psychological research shows that HGS is correlated with a number of social variables, but only in males. We conducted three studies to further investigate the relationship between HGS and measures of aggression and social competition among adolescents. Consistent with previous reports, correlations were almost exclusive to males, but this was only visible during late adolescence (i.e., high school). These findings support evolutionary hypotheses regarding grip strength in male-male competition and suggest that similar to measures of testosterone, HGS is a measure that is predictive of social behavior in older adolescent males.     

Psychopathology of adolescent suicide: hopelessness, coping beliefs, and depression

Two studies of adolescents examined the relation of several cognitive variables and depression to suicide-related behaviors. Study 1 compared hopelessness and depression in 281 high school students. Unlike research with adults, depression was significantly related to suicidal behaviors, even after hopelessness was statistically controlled. When depression was controlled, hopelessness was unrelated to suicidal behaviors for boys and only modestly related for girls. Study 2 examined depression, hopelessness, survival-coping beliefs, fear of social disapproval, and social desirability in relation to suicidal behaviors in 53 male juvenile delinquents. Again, hopelessness did not account for a significant proportion of the variance in suicide. Depression was uniquely related to past suicide attempts. Survival-coping beliefs were associated with self-predicted future suicide and other suicidal behaviors. Survival-coping beliefs are discussed as a cognitive buffer to suicidal ideation in adolescence.     

Attributions for social failure and aggression in incarcerated delinquent youth

While a variety of cognitive deficits and biases have been found to characterize aggressive and delinquent children and youth, very little attention has focused on determining whether aggressive youth also display deviant attributional beliefs in response to social failure. Research in the more impersonal cognitive domains such as achievement has shown attributions for failure to be potent determinants of both affective rections and subsequent responding. Thus, the present study was designed to investigate whether specific attributional patterns following social failure may also relate to aggressive behavior. The aim of this study was to determine the relation betweeen the level of self-reported physical aggression and specific atttributional patterns following hypothetical social failure in a sample of incarcerated delinquent males. While the general hypotheses were that increased aggressiveness would be related to a greater tendency to endorse attributions for social failure that are external, stable, and controllable, only the hypothesis with regard to controllability was supported. The findings are discussed in terms of the relation between cognition and aggression in delinquent youth.This research was supported in part by grant MH 44768-01 from the National Institute of Mental Health to the first author.

Reading and Empathy

The relationship between reading and empathy was explored. Controlling for GPA and gender, reading variables were hypothesized as related to empathy; the relationship was expected to differ for males and females. For the complete sample, affective components were related to GPA but not reading. Perspective taking was related to reading appreciation but not GPA. For females, reading appreciation was related to perspective taking and empathic concern. For males, GPA and non-fiction reading were positively related, but both were negatively related to empathic concern. Results suggest reading may promote both academic achievement and social development. Findings and social implications are discussed.     

The "cost of caring" in youths' friendships: considering associations among social perspective taking, co-rumination, and empathetic distress

The current research considered the costs of caring in youths' friendships. The development of a new construct, empathetic distress, allowed for a direct test of the commonly held belief that females suffer greater vicarious distress in response to close others' stressors and problems than do males. Empathetic distress refers to one's strongly sharing a relationship partner's distress over problems to the point of taking on the partner's distress and experiencing it as one's own. This new construct was examined in an ethnically diverse sample of early adolescents who responded to a series of questionnaires in their classrooms. Results indicated that girls did experience greater empathetic distress in friendships than did boys. In addition, the current research revealed that social perspective taking in friendships (i.e., the social-cognitive ability to infer and understand the friend's perspective) had adjustment trade-offs in that it predicted greater positive friendship quality but also greater empathetic distress in the friendship. Interestingly, the associations of social perspective taking with both positive friendship quality and empathetic distress were partially mediated by co-rumination or excessive discussion of problems. Applied implications of the findings that girls' greater social perspective taking and associated co-rumination contributed both to their greater positive friendship quality but also to greater costs of caring in the form of empathetic distress are discussed.     

Why are Girls Less Physically Aggressive than Boys? Personality and Parenting Mediators of Physical Aggression

The primary goal of the present analysis was todetermine whether the commonly observed genderdifference in physical aggression could be accounted forby gender differences in selected personality and social contextual factors. Eighty-nineadolescents (M age = 16.0; 52% female; 53%European-Americans, 38% Latinos)completed self-reportmeasures, including sympathy (empathic concern andperspective taking) and parental involvement (support andmonitoring). Mediation analyses revealed that relativelyhigh levels of both empathic concern and parentalmonitoring accounted for relatively low levels ofphysical aggression. In addition, sympathy (for males)and parental involvement (males and females) werenegatively related to physical aggression. Discussionfocused on theoretical and practical implications of these findings.     

自恋与攻击行为的关系:观点采择和共情关注的调节作用

为考察自恋对攻击行为的影响以及观点采择和共情关注在其中的调节效应,采用自恋人格问卷、人际反应指针量表和简版Buss-Perry攻击问卷,对562名大学生进行调查。结果发现:(1)自恋显著正向预测攻击行为;(2)观点采择和共情关注均可负向调节自恋与攻击行为的关系,两者都能显著抑制高自恋者的攻击行为,却无法影响低自恋者的攻击行为。因此,提高观点采择和增强共情关注是减少高自恋者攻击行为的重要途径。     

Female juvenile delinquency, motherhood, and the intergenerational transmission of aggression and antisocial behavior

The current study explored the intergenerational transmission of aggression and antisocial behavior by examining mothers' juvenile delinquency, their pregnancies, and its impact on their children's aggressive behavior. The sample consisted of the first 181 biological mothers recruited as part of the Vancouver Longitudinal Study on the Psychosocial Development of Children (British Columbia, Canada). Results indicated that mothers who were juvenile delinquents were more likely to experience social adversity, to use substances during pregnancy and to offend in adulthood. Furthermore, mothers who reported juvenile delinquency had children who were more physically aggressive and had an earlier onset of physical aggression. This pattern of association held when controlling for sociodemographics, social adversities, prenatal substance exposure, and criminal involvement in adulthood. The study findings highlighted the importance of understanding the role and impact of female delinquency and motherhood on the intergenerational transmission of antisocial behavior.
