亲密伴侣暴力（IPV）是一种复杂的全球现象，需要多视角分析。然而，与其他类型的暴力研究相比，针对这一问题进行的神经科学研究数量很少，也没有进行过将施暴者与其他罪犯进行比较的神经影像学研究。因此，这项研究的主要目的是比较施暴者与其他罪犯在接触 IPV 或一般暴力图片时的大脑功能。对 21 名施暴者和其他 20 名罪犯进行了功能磁共振成像研究，同时观察 IPV 图像 (IPVI)、一般暴力图像 (GVI) 和中性图像 (NI)。结果表明，与其他罪犯相比，与 NI 相比，IPVI 的施虐者在前扣带皮层、后扣带皮层以及中前额叶皮层中表现出较高的激活，而在上前额叶皮层中表现出较低的激活。每组 IPVI 和 GVI 之间的配对 t 检验比较显示，仅在施虐者组中，内侧前额叶皮层、后扣带皮层和左角皮层与 IPVI 相关。这些结果可能对更好地理解 IPV 现象具有重要意义。
Intimate partner violence (IPV) is a complex and global phenomenon that requires a multi-perspective analysis. Nevertheless, the number of neuroscientific studies conducted on this issue is scarce as compared with studies of other types of violence, and no neuroimaging studies comparing batterers to other criminals have been conducted. Thus, the main aim of this study was to compare the brain functioning of batterers to that of other criminals when they are exposed to IPV or general violence pictures. An fMRI study was conducted in 21 batterers and 20 other criminals while they observed IPV images (IPVI), general violence images (GVI) and neutral images (NI). Results demonstrated that batterers, compared with other criminals, exhibited a higher activation in the anterior and posterior cingulate cortex and in the middle prefrontal cortex and a decreased activation in the superior prefrontal cortex to IPVI compared to NI. The paired t-test comparison between IPVI and GVI for each group showed engagement of the medial prefrontal cortex, the posterior cingulate and the left angular cortices to IPVI in the batterer group only. These results could have important implications for a better understanding of the IPV phenomenon.
