这项调查的目的是确定支持对有意和无意违反社会规范的处理的神经系统。使用与事件相关的功能磁共振成像，我们通过比较描述正常行为、尴尬情况或违反社会规范的故事的神经反应来解决这个问题。对违反社会规范的行为进行处理涉及到以前被报道在代表他人心理状态方面发挥作用的系统，即内侧前额叶和颞叶区域。此外，对违反社会规范的行为的处理涉及以前发现的对厌恶情绪表达(特别是愤怒情绪)做出反应的系统；即外侧眼眶前额叶皮质(Brodmann区47)和内侧前额叶皮质。对于故意和无意违反社会规范的行为，观察到的反应类似，尽管故意违反社会规范的行为更为明显。这些数据表明，额叶病变或额颞痴呆患者的社会行为问题可能是系统内功能障碍的结果，根据它们在处理特定社会行为是否适当的过程中可能发挥的作用。
The aim of this investigation was to identify neural systems supporting the processing of intentional and unintentional transgressions of social norms. Using event-related fMRI, we addressed this question by comparing neural responses to stories describing normal behaviour, embarrassing situations or violations of social norms. Processing transgressions of social norms involved systems previously reported to play a role in representing the mental states of others, namely medial prefrontal and temporal regions. In addition, the processing of transgressions of social norms involved systems previously found to respond to aversive emotional expressions (in particular angry expressions); namely lateral orbitofrontal cortex (Brodmann area 47) and medial prefrontal cortex. The observed responses were similar for both intentional and unintentional social norm violations, albeit more pronounced for the intentional norm violations. These data suggest that social behavioural problems in patients with frontal lobe lesions or fronto-temporal dementia may be a consequence of dysfunction within the systems identified in light of their possible role in processing whether particular social behaviours are, or are not, appropriate.
