Ex-combatants often exhibit atypical Emotional Processing (EP) such as reduced emphatic levels and higher aggressive attitudes. Social Cognitive Training (SCT) addressing socio-emotional components powerfully improve social interaction among Colombian ex-combatants. However, with narrow neural evidence, this study offers a new testimony. A sample of 28 ex-combatants from Colombian illegal armed groups took part in this study, split into 15 for SCT and 13 for the conventional program offered by the Governmental Reintegration Route. All of them were assessed before and after the intervention with a protocol that included an EP task synchronized with electroencephalographic recordings. We drew behavioral scores and brain connectivity (Coherency) metrics from task performance. Behavioral scores yielded no significant effects. Increased post-intervention connectivity in the delta band was observed during negative emotional processing only SCT group. Positive emotions exposed distinctive gamma band connectivity that differentiate groups. These results suggest that SCT can trigger covert neurofunctional reorganization in ex-combatants embarked on the reintegration process even when overt behavioral improvements are not yet apparent. Such covert functional changes may be the neural signature of compensatory mechanisms necessary to reshape behaviors adaptively. This novel framework may inspire cutting-edge translational research at the crossing of neuroscience, sociology, and public policy-making.
前战斗人员通常表现出非典型的情绪处理（EP），例如同理心水平降低和攻击性态度增强。针对社会情感成分的社会认知训练（SCT）有力地改善了哥伦比亚前战斗人员之间的社会互动。然而，由于神经证据有限，这项研究提供了新的证据。这项研究的参与者是来自哥伦比亚非法武装组织的 28 名前战斗人员，其中 15 人参加了 SCT，13 人参加了政府重返社会途径提供的常规方案。他们所有人都在干预前后接受了评估，评估包括一个与脑电图记录同步的 EP 任务。我们从任务表现中提取行为评分和大脑连通性（相干性）指标。行为评分没有显示出显著的效果。只有 SCT 组在处理负面情绪时观察到干预后 delta 波段的连通性增加。积极情绪表现出独特的伽马波段连通性，可区分不同的组别。这些结果表明，即使明显的行为改善尚未显现，SCT 可以在前战斗人员重新融入社会的过程中引发潜在的神经功能重组。这种潜在的功能变化可能是重塑行为适应性所需的补偿机制的神经特征。这个新的框架可能会激发神经科学、社会学和公共政策制定交叉领域的前沿转化研究。
