We investigated neural correlates of traumatic experience related to the lack of family care in adults with a history of institutionalization (IC) using the Emotional Stroop paradigm. The goals of our study were twofold: we investigated whether adults with IC history (n = 24; M_age = 22.17, SD = 6.7) demonstrate atypical processing of emotionally salient words in general, and whether they exhibit selective processing bias toward family related words compared to adults raised in biological families (BFC; n = 28; M_age = 22.25, SD = 4.9). Results demonstrated significant differences in accuracy but not response times between groups on the behavioral level, indicating that the IC group was overall less accurate in identifying the color of the font. Contrary to our prediction, there were no significant differences between neural response to family related versus unrelated words in the IC and BFC groups. The absence of group differences can be explained by the selection of stimuli, which were associated with family rather than institutional history. The IC group showed a larger N280‐380 component in response to negative words compared to the BFC group, and larger negativity in the right parietal area in response to positive words in the same time window. Results demonstrate that institutional history is marked by altered emotional processing in the subpopulation of institutional care‐leavers, but the footprint is not specific to traumatic experience and extends from general sensitivity to emotional words.

具有机构化历史的成年人情感词的神经处理发生变化：来自情感Stroop任务的证据

我们使用情绪化Stroop范式调查了有家庭化病史的成人中缺乏家庭护理的创伤经历的神经相关性。我们的研究目标是双重的：我们调查了具有IC病史（n  = 24；M_年龄 = 22.17，SD  = 6.7）的成年人是否总体上表现出对情感突出单词的非典型处理，以及他们是否表现出对家庭相关单词的选择性处理偏见与在生物学家庭中成长的成年人相比（BFC；n  = 28；M_年龄 = 22.25，SD = 4.9）。结果表明，在行为水平上，两组之间的准确性存在显着差异，但响应时间没有差异，这表明IC组在识别字体颜色方面总体上不那么准确。与我们的预测相反，在IC和BFC组中，对家庭相关词和无关词的神经反应之间没有显着差异。群体差异的缺乏可以通过选择刺激来解释，这些刺激与家庭而不是机构历史有关。与BFC组相比，IC组对负词的反应显示出更大的N280-380分量，而在同一时间窗口中，对正词的反应，右顶区的负电荷更大。
