本杂志最后一期的两篇报告试图复制我们之前关于前部脑电图 (EEG) 不对称、情感风格和抑郁的研究。在这篇评论中，概述了我们的前部不对称、情感风格和精神病理学模型。重点是概念化包括皮质和皮质下结构的回路内的前额叶和前颞叶激活模式。考虑了情感风格和精神病理学产生中不对称激活的个体差异的因果状态。主要重点放在脑电图方法上，特别是需要进行多次评估以获得更好地反映个人真实分数的不对称激活估计。还考虑了这两篇文章中每一篇的具体问题。每篇文章与我们之前发表的数据的一致性都比作者自己暗示的要高。提出了未来研究的建议，以解决一些悬而未决的问题。
Two reports in the last issue of this journal attempted to replicate aspects of our previous studies on anterior electroencephalogram (EEG) asymmetry, affective style, and depression. In this commentary, an overview is provided of our model of anterior asymmetries, affective style, and psychopathology. Emphasis is placed on conceptualizing the prefrontal and anterior temporal activation patterns within a circuit that includes cortical and subcortical structures. The causal status of individual differences in asymmetric activation in the production of affective style and psychopathology is considered. Major emphasis is placed on EEG methods, particularly the need for multiple assessments to obtain estimates of asymmetric activation that better reflect an individual's true score. Issues specific to each of the two articles are also considered. Each of the articles has more consistency with our previously published data than the authors themselves suggest. Recommendations are made for future research to resolve some of the outstanding issues.
