在生命早期明显的静息脑电不对称被认为会使情感行为产生偏差，并有助于精神病理学的发展。然而，目前尚不清楚这种偏见发生在信息处理的哪个阶段。不对称性可以作为传入过滤器，调节对传入刺激的情绪反应;或者作为传出过滤器，调节情绪条件下的行为反应倾向。本研究以209名6.03岁幼儿为被试，对两个模型的预测结果进行了检验。静息不对称性进行了检查，结合皮肤电和心脏的生理反应措施，四个情绪诱导的电影剪辑（恐惧，悲伤，快乐，愤怒）和教师的精神病理学评级。结果证实了右侧皮质激活增加与内化症状严重程度以及左侧激活与外化症状严重程度之间的关联。静息不对称和生理反应之间的显着相互作用的情绪表明，生理反应缓和静息不对称和精神病理学症状之间的关联。(c)2012 Wiley Periodicals，Inc.

Resting EEG asymmetry evident early in life is thought to bias affective behaviors and contribute to the development of psychopathology. However, it remains unclear at what stage of information processing this bias occurs. Asymmetry may serve as an afferent filter, modulating emotional reactivity to incoming stimuli; or as an efferent filter, modulating behavioral response tendencies under emotional conditions. This study examines 209 kindergarten children (M=6.03 years old) to test predictions put forth by the two models. Resting asymmetry was examined in conjunction with electrodermal and cardiac measures of physiological reactivity to four emotion-inducing film clips (fear, sad, happy, anger) and teacher ratings of psychopathology. Results confirm an association between increased right side cortical activation and internalizing symptom severity as well as left activation and externalizing symptom severity. Significant interactions between resting asymmetry and physiological reactivity to emotion indicate that physiological reactivity moderates the association between resting asymmetry and symptoms of psychopathology.
