Callous-unemotional (CU) traits in antisocial youth have been associated with deficits in the processing of emotionally distressing stimuli in a number of past studies. In the current study, we investigated moderators of this association in a sample of 88 ethnically diverse detained boys (mean age = 15.57, SD = 1.28). Overall, emotional processing of distressing stimuli using a dot-probe task was not related to CU traits and there was no moderating effect of ethnicity. However, CU traits were related to deficits in emotional processing in youth high on aggression and youth high on exposure to community violence. Further, youth high on CU traits but with enhanced orienting to distressing stimuli had stronger histories of abuse, supporting the possibility that there may be environmentally influenced pathways in the development of these traits.
过去的一些研究表明，反社会青年的冷酷无情（CU）特质与处理情绪困扰刺激的缺陷有关。在本研究中，我们对88名来自不同种族的被拘留男孩（平均年龄 = 15.57，标准差 = 1.28）进行了调查，以探究这种关联的调节因素。总体而言，使用点探测任务对困扰刺激进行的情绪处理与CU特质无关，且种族不存在调节作用。然而，CU特质与攻击性高的青少年以及社区暴力暴露程度高的青少年在情绪处理方面的缺陷有关。此外，CU特质高但对困扰刺激的定向增强的青少年有更强的受虐史，这支持了这些特质发展中可能存在环境影响途径的可能性。
