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。
Callous-unemotional(CU) trait is a personality disposition which exhibits callous use of others,lack of guilt,absence of empathy.CU is a predictive factor of aggressive antisocial behavior and even violent criminal behavior in youth and adult people.CU trait is associated with emotional impairment such as negative emotional processing deficits and absence of empathy,and cognitive problems such as reward-oriented behavior and punishment insensitivity.Biologically,individuals with CU trait show low arousing level,low cortisol,abnormal reaction of amygdala and ventral medial prefrontal cortex.Further researches is needed to revise and develop local CU traits scales,investigate the gender difference of CU trait,explore the association of CU traits with other mental disorders such as oppositional defiant disorder,and provide evidence for violent criminal corrections.
