Expressive suppression is an emotion regulation strategy that requires interoceptive and emotional awareness. These processes both recruit the anterior insula. It is not known, however, whether increased use of expressive suppression is associated with increased anterior insula volume. In the present study, high-resolution anatomical MRI images were used to calculate insula volumes in a set of 50 healthy female subjects (mean 21.9 years) using both region of interest (ROI) and voxel-based morphometry (VBM) approaches. Participants also completed trait measures of expressive suppression usage, cognitive reappraisal usage, and negative emotional reactivity (the latter two served as control measures). As predicted, both ROI and VBM methods found that expressive suppression usage, but not negative affect and cognitive reappraisal, was positively related to anterior insula volume. These findings are consistent with the idea that trait patterns of emotion processing are related to brain structure.
表达抑制是一种需要内感受和情绪意识的情绪调节策略。这些过程都需要前脑岛的参与。然而,目前尚不清楚增加表达抑制的使用是否与前脑岛体积的增加有关。在本研究中,使用高分辨率解剖 MRI 图像,通过感兴趣区 (ROI) 和基于体素的形态测量学 (VBM) 方法,对 50 名健康女性受试者(平均年龄 21.9 岁)的脑岛体积进行了计算。参与者还完成了表达抑制使用、认知重评使用和负性情绪反应的特质测量(后两者作为对照测量)。正如预测的那样,ROI 和 VBM 方法都发现,表达抑制的使用与前脑岛体积呈正相关,而不是与负性情绪和认知重评相关。这些发现与这样一种观点一致,即情绪处理的特质模式与大脑结构有关。
