摘要

哥伦比亚前战斗人员的重新融入过程受到他们长期暴露于暴力的阻碍,这影响了他们的情绪处理(EP)。描述他们的EP特征将有助于他们重新加入。这项工作的目的是定义一种基于脑电图的大脑连接方法,以识别哥伦比亚前战斗人员和未直接接触武装冲突的个人之间的脑电图差异。所提出的方法包括定义感兴趣区域(ROI),并从五种常用的大脑连接指标中选择一种:相关性、相互相关性、相干性、相干性虚部和相位滞后指数。正效性刺激在β频带存在显著性差异。这些结果支持了先前文献中关于前战斗人员处理积极效价情绪信息的困难的趋势。

Detecting atypical functioning of emotional processing in Colombian ex-combatants
The reincorporation process of Colombian ex-combatants is hindered by their chronic exposure to violence, which affects their Emotional Processing (EP). Characterizing their EP will contribute to their reinsertion. The objective of this work is to define an EEG-based brain connectivity approach to identify differences in EP between Colombian ex-combatants and individuals who were not directly exposed to the armed conflict. The proposed approach involves defining the Regions of Interest (ROI) and selecting one of five commonly used brain connectivity metrics: Correlation, Cross-Correlation, Coherence, Imaginary part of Coherency, and Phase-Lag Index. Significant differences were found in the positive valence stimuli in the Beta frequency band. These results support the previously reported trend in the literature regarding the difficulties ex-combatants have to process emotional information with positive valence.
