The aim of this study was to examine stability and change in genetic and environmental influences on reactive (impulsive and affective) and proactive (planned and instrumental) aggression from childhood to early adolescence. The sample was drawn from an ongoing longitudinal twin study of risk factors for antisocial behavior at the University of Southern California (USC). The twins were measured on two occasions: ages 9–10 years (N=1,241) and 11–14 years (N=874). Reactive and proactive aggressive behaviors were rated by parents. The stability in reactive aggression was due to genetic and nonshared environmental influences, whereas the continuity in proactive aggression was primarily genetically mediated. Change in both reactive and proactive aggression between the two occasions was mainly explained by nonshared environmental influences, although some evidence for new genetic variance at the second occasion was found for both forms of aggression. These results suggest that proactive and reactive aggression differ in their genetic and environmental stability, and provide further evidence for some distinction between reactive and proactive forms of aggression.

This study investigated how hope influences the relationship between discrimination and depressive symptoms. Results from participants' (N = 318) responses suggest that increased levels of hope were directly related to decreased levels of depressive symptoms. However, increased levels of hope were also related to a stronger relationship between discrimination and depressive symptoms. Este estudio investigó cómo la esperanza influye en la relación entre discriminación y síntomas depresivos. Los resultados obtenidos a partir de las respuestas de los participantes (N = 318) sugieren que unos niveles más elevados de esperanza estuvieron directamente relacionados con unos niveles más bajos de síntomas depresivos. Sin embargo, los niveles superiores de esperanza también estuvieron relacionados con una relación más fuerte entre discriminación y síntomas depresivos.  相似文献

While the question of how to integrate Romani communities has increased in political significance since the 1990s, a consensus has yet to be reached on how best to design integration policies for such a heterogeneous group of people. This article examines debates on whether ethnoculturally specific or neutral policies are more appropriate. Using the Czech Romani integration policy as a case study, it identifies as a significant problem the conflation of the Romani ethnic identity with the low socio‐economic status of many (but not all) Roma. This has led to a policy focus on programmes to tackle social deprivation rather than addressing the discrimination which affects all Roma regardless of class. As a consequence of the decentralisation of power in the Czech Republic and the ingrained nature of anti‐Romani prejudice, policies, whether ethnoculturally neutral or specific, will be implemented or rejected at the local level on the basis of local priorities.  相似文献

Certain personality traits have been associated with impulsive aggression in both college and community samples, primarily irritability, anger/hostility, and impulsivity. The literature regarding the psychopathology associated with impulsive aggression is relatively sparse and strongly emphasizes DSM‐IV‐TR [APA, 2000] Axis II personality disorders, although some comorbidity with Axis I clinical disorders has been reported. The current study compares impulsive aggressive (IA) college students with their non‐aggressive peers on several self‐report measures of personality and psychopathology. Personality results were as predicted, with IAs scoring higher than controls on measures of impulsivity and aggression. Additionally, the Psychopathic Personality Inventory (PPI), which was given for exploratory purposes, revealed a unique pattern of psychopathic traits in impulsive aggression that contained key differences from the callous‐unemotional profile seen in premeditated aggression. Contrary to our hypothesis that a specific pattern of psychopathology (personality disorders, bipolar disorder, and adult attention deficit hyperactivity disorder) would emerge for impulsive aggression, IAs scored significantly higher than controls on nearly every clinical scale of the Personality Assessment Inventory (PAI; Somatic Complaints, Anxiety, Anxiety‐Related Disorders, Depression, Mania, Schizophrenia, Borderline Features, Antisocial Features, Alcohol Problems, and Drug Problems), indicating a global elevation of psychopathology. In conclusion, while the personality traits and behaviors that characterize impulsive aggression are relatively consistent across individuals, its associated psychopathology is unexpectedly variable.

The relative role of the timing and repetition of misinformation on the accuracy of children's recall was examined in two experiments. Kindergarten children participated in a magic show and about 40 days later had a memory test. Between the magic show and the memory test, the children were suggestively interviewed either one time in a relatively ‘early’ interview (temporally closer to the magic show than the memory test) or a relatively ‘late’ interview (closer to the memory test than the magic show), or in both suggestive interviews. The timing of the suggestive interviewing was manipulated so that the interview was temporally distant from the event or memory test or temporally close to the event or memory test. Repeated interviewing heightened misinformation effects only when the children received the two interview sessions temporally close to the event and memory test.

The current experiment explored the effect of activating a counterfactual mind‐set on the discussion of unique information and group judgment accuracy. Evidence suggests that a counterfactual mind‐set is characterized by a focused, analytic mental state and, when activated at the group level, improves group judgment accuracy in the murder mystery paradigm (a hidden profile task). We hypothesized that the beneficial effect of the counterfactual mind‐set would only help group problem‐solving tasks if the mind‐set had been activated at the group level, allowing the analytical mind‐set to play out in an atmosphere of synergistic coordination. In contrast, if this highly focused mental state is activated at the individual level, it could impair group judgment quality because inwardly focused analytical individuals may fail to coordinate their behavior with other group members. Consistent with our hypothesis, activating a counterfactual mind‐set at the individual level had a debilitating effect on the group judgment task, whereas activating a counterfactual mind‐set at the group level had a facilitative effect, increasing information sharing, synergistic coordination and judgment accuracy.

Psychosocial buffers were evaluated for their relative contributions to adolescents' perceived risk for suicide. A community sample of African American and White adolescents (N = 1,098) rated the likelihood that they would die by suicide and completed standardized measures of depression, hopelessness, intrinsic and extrinsic religiosity, orthodoxy, social support, and causal attributional style. Orthodoxy-commitment to core beliefs-emerged as the single strongest correlate after controlling for the effects of other buffers. The effect of depression on perceived suicide risk was moderated by the adolescent's degree of orthodoxy. Commitment to core, life-saving beliefs may help explain the religion-suicide link for adolescents.  相似文献

This study examined the comparative efficacy of two brief techniques for facilitating eyewitness memory in police investigations. Adult and child participants (N = 126; 64 children and 62 adults) who had viewed a videotape of a crime were subsequently tested for their memory of the event following either a focused meditation procedure (FM, derived from hypnotic interviewing techniques), a context reinstatement procedure (CR, a component of the cognitive interview), or a control procedure (no memory facilitation instructions). For both adults and children, the FM and CR procedures enhanced performance on both open‐ended and closed questions to levels above those achieved by controls, although those in the CR condition produced significantly more correct responses than those in the FM condition. However, only those in the CR group displayed elevated levels of confidence in relation to incorrect responses on closed questions. Implications for the possible use of such procedures are discussed.
