Recent findings associate attachment insecurity (assessed as levels of attachment anxiety and avoidance) with poor emotion regulation. In turn, emotion regulation has been shown to be associated with hippocampus (HC) functioning and structure. Clinical disorders such as depression and PTSD, which have been previously associated with attachment insecurity, are also known to be linked with reduced hippocampal cell density. This suggests that attachment insecurity may also be associated with reduced hippocampal cell density. We examined this hypothesis using T1 images of 22 healthy young adults. In line with our hypothesis, attachment avoidance was associated with bilateral HC reduction, whereas attachment anxiety was significantly related to reduced cell concentration in the left HC. The findings are compatible with a neurotoxical model of stress-induced cell reduction in the HC, providing further information on emotion regulation abilities among insecurely attached individuals.
最近的研究发现，依恋不安全感（通过评估依恋焦虑和回避水平来衡量）与情绪调节能力差有关。情绪调节反过来又与海马体（HC）的功能和结构有关。先前与依恋不安全感相关的临床障碍，如抑郁症和 PTSD，也与海马体细胞密度降低有关。这表明，依恋不安全感也可能与海马体细胞密度降低有关。我们使用 22 名健康年轻成年人的 T1 图像来检验这一假设。与我们的假设一致，依恋回避与双侧 HC 减少有关，而依恋焦虑与左侧 HC 中细胞浓度降低显著相关。这些发现与应激诱导的 HC 中细胞减少的神经毒性模型一致，为依恋不安全感个体的情绪调节能力提供了更多信息。
