Research aimed at identifying and studying subtypes of aggression have historically dichotomized aggressive subtypes, although specific nomenclature has varied; one approach has been to classify aggressive behavior as predominantly impulsive or predominantly premeditated. There are a number of behavioral and cognitive differences between those exhibiting these different forms of aggression. This study was designed to extend understanding of the impulsive/premeditated aggression dichotomy by comparing time estimation among adolescents exhibiting predominantly impulsive or predominantly premeditated forms of physical aggression who have a psychiatric diagnosis of conduct disorder (CD). Time estimation has previously been shown to be disrupted in impulsive and some aggressive individuals. Time estimation was compared between healthy Controls (n = 37) and two groups of adolescents with CD, those with histories of either predominantly impulsive (CD-Impulsive, n = 26) or predominantly premeditated (CD-Premeditated, n = 38) aggressive behaviors. Participants completed five computerized trials during which they estimated when 1 min had passed. Among aggressive adolescents with CD, the misperception of time was specific to those with histories of impulsive aggression, although time estimates improved with repeated testing and performance feedback. This study confirms the importance of considering the role and type of physical aggression when studying heterogeneous diagnostic groups like CD and supports the relevance of time estimation to certain subgroups of adolescents with CD.
旨在识别和研究攻击亚型的研究，历史上一直将攻击亚型二分法，尽管具体的命名有所不同；一种方法是将攻击行为主要分类为冲动型或预谋型。表现出这些不同形式攻击行为的个体之间存在许多行为和认知差异。本研究旨在通过比较患有品行障碍（CD）的青少年中，主要表现出冲动型或预谋型身体攻击行为的青少年的时间估计，来扩展对冲动/预谋攻击二分法的理解。先前已表明，时间估计在冲动型和一些攻击型个体中会受到干扰。在健康对照组（n = 37）和两组患有CD的青少年之间比较时间估计，这两组青少年分别具有主要为冲动型攻击行为史（CD-冲动型，n = 26）或主要为预谋型攻击行为史（CD-预谋型，n = 38）。参与者完成了五项计算机化试验，在此期间他们估计1分钟何时过去。在患有CD的攻击性青少年中，时间误判特定于那些有冲动攻击行为史的青少年，尽管时间估计随着重复测试和表现反馈而有所改善。本研究证实了在研究像CD这样的异质性诊断群体时，考虑身体攻击的作用和类型的重要性，并支持时间估计与患有CD的某些青少年亚组的相关性。
