Abstract

Callous-unemotional (CU) traits are associated with severe and persistent juvenile offending. CU traits are also associated with dampened emotional arousal, which suggests that fundamental frequency (f₀), a measure of vocally-encoded emotional arousal, may serve as an accessible psychophysiological marker of CU traits in youth. This study investigated the associations between f₀ range measured during an emotionally evocative task, CU traits, and emotion dysregulation in a mixed-gender sample of 168 justice-involved youth. For boys, after controlling for covariates, wider f₀ range-indicating greater emotional arousal-was negatively associated with CU traits and positively associated with emotion dysregulation. For girls, no significant associations with f₀ range emerged; however, CU traits were positively associated with emotion dysregulation. Findings suggest that f₀ range may serve as a valid indicator of CU traits in JJ-involved boys, and that detained boys and girls with high CU traits are characterized by different profiles of emotion dysregulation.

用声音编码的情绪唤醒作为涉法青少年冷酷无情特征的标记。

冷酷无情（CU）特质与严重和持续的青少年犯罪有关。CU特质还与情绪唤醒减弱有关，这表明基频（f0）作为一种测量声音编码情绪唤醒的指标，可以作为青少年CU特质的心理生理学标记。本研究调查了在一项情绪唤起任务中测量的f0范围、CU特质和情绪失调之间的关联，研究对象是168名涉案青少年的混合性别样本。对男孩来说，在控制了协变量后，更宽的f0范围（表示更大的情绪唤起）与CU特质呈负相关，而与情绪失调呈正相关。对于女孩来说，f0范围与情绪失调没有明显的关联；但是，CU特质与情绪失调呈正相关。研究结果表明，f0范围可作为衡量有JJ卷入的男孩的CU特质的有效指标，而被拘留的男孩和具有高CU特质的女孩具有不同的情绪失调特征。
