本评论回顾了一些旧的数据，关于Obergy和Levenson（2019）在其目标论文中描述的相同类型的视觉回避行为，并提出了关于这种行为的神经基础的新观点。在单侧脑损伤患者的情绪表达研究中，意外地观察到对令人震惊的电影片段缺乏视觉回避（Mammucari等人，1988年）。右半球脑损伤的受试者缺乏视觉回避，这归因于这些患者的情感冷漠。这些结果可以补充Obergy和Levenson（2019）的结果，主要有两个原因：（1）它们涉及情绪功能的半球间组织，而不是半球内组织;（2）它们可以在FTD患者中复制。事实上，萎缩在这些受试者中往往是不对称的，最近的几项调查表明，当右额叶或颞叶萎缩时，情绪障碍可能是最重要的。本评论表明，这两个以前独立的神经心理学研究之间的一个富有成效的整合是可能的。
The present commentary revisits some old data, concerning the same kind of visual avoidance behaviors described by Otero and Levenson's (2019) in their target paper and proposes a new perspective on the neural underpinnings of such behaviors. A lack of visual avoidance in response to a shocking film clip had been unexpectedly observed during a study of emotional expression in patients with unilateral brain damage (Mammucari et al., 1988). This lack of visual avoidance in subjects with right hemisphere brain lesions was attributed to the emotional indifference of these patients. These results could be complementary to those obtained by Otero and Levenson (2019) for two main reasons: (1) they concerned the inter-hemispheric, rather than the intra-hemispheric organization of emotional functions; (2) they could be replicated in FTD patients. Atrophy is, in fact, often asymmetrical in these subjects and several investigations have recently shown that emotional disorders can be on the foreground when atrophy prevails in the right frontal or temporal lobes. The present commentary suggests that a fruitful integration is possible between these two previously independent lines of neuropsychological research.
