Personality is related to psychopathology and its higher-order structures, but there is little research regarding neurobiological associations of higher-order psychopathology factors. This study examined the factor structure of a wide range of psychopathology and its associations with both personality and emotional reactivity revealed through the late positive potential (LPP) in a sample of 275 undergraduates. A three-factor structure of psychopathology emerged comprising Internalizing (INT), Externalizing (EXT), and Aberrant Experiences (ABX). EXT predicted aggressive disconstraint, whereas both INT and ABX predicted Alienation and Stress Reaction. INT uniquely predicted low Well-Being, and ABX predicted a rigid absorption combined with interpersonal detachment. ABX correlated with reduced parietal emotional LPP reactivity, whereas INT correlated with stronger frontal LPP reactivity to emotional versus neutral pictures.
人格与精神病理学及其高阶结构相关，但关于高阶精神病理学因素的神经生物学关联的研究较少。本研究在275名本科生样本中，考察了广泛的精神病理学的因素结构及其与人格和通过晚期正电位（LPP）揭示的情绪反应性的关联。出现了一个由内化（INT）、外化（EXT）和异常体验（ABX）组成的三因素精神病理学结构。EXT预测攻击性行为不受约束，而INT和ABX都预测疏离感和应激反应。INT独特地预测低幸福感，而ABX预测僵化专注与人际疏离相结合。ABX与顶叶情绪LPP反应性降低相关，而INT与对情绪图片与中性图片的额叶LPP反应性更强相关。
