Despite increasing support for the distinction between primary and secondary variants of callous-unemotional features in children with disruptive behavioural disorders, evidence about whether emotion recognition deficits are only characteristic of primary CU is inconclusive. We tested whether, in young children with Oppositional Defiant Disorder (ODD; N = 74), level of affective arousal moderated the association between CU and performance on behavioural measures of emotional abilities. The association between CU and emotion recognition abilities was dependent on the child's level of affective arousal with higher CU associated with poorer emotion recognition abilities for ODD children with lower affective arousal (r = - 0.49; p = .007) but not for those with higher levels (r = 0.03; p = .838). Our results replicate recent findings and give support to the notion that the primary CU variant is characterised emotionally by under arousal of affect, low affect dysregulation and impaired emotion recognition abilities.
尽管越来越多的人支持将具有破坏性行为障碍的儿童的冷酷无情特征分为原发性和继发性变异，但关于情感识别缺陷是否仅为原发性 CU 所特有的证据尚无定论。我们测试了在患有对立违抗性障碍（ODD；N=74）的幼儿中，情感唤起水平是否调节了 CU 与情绪能力行为测量表现之间的关系。CU 与情绪识别能力之间的关联取决于儿童的情感唤起水平，对于情感唤起水平较低的 ODD 儿童，较高的 CU 与较差的情绪识别能力相关（r=-0.49;p=0.007），而对于情感唤起水平较高的儿童则没有相关性（r=0.03;p=0.838）。我们的研究结果再现了最近的发现，并支持这样一种观点，即原发性 CU 变异在情感上表现为情感唤起不足、情感调节能力低下和情绪识别能力受损。
