Abstract
Recent neuroimaging studies suggest lateralized cerebral mechanisms in the right temporal parietal junction are involved in complex social and moral reasoning, such as ascribing beliefs to others. Based on this evidence, we tested 3 anterior-resected and 3 complete callosotomy patients along with 22 normal subjects on a reasoning task that required verbal moral judgments. All 6 patients based their judgments primarily on the outcome of the actions, disregarding the beliefs of the agents. The similarity in performance between complete and partial callosotomy patients suggests that normal judgments of morality require full interhemispheric integration of information critically supported by the right temporal parietal junction and right frontal processes.
摘要
最近的神经影像学研究表明，右侧颞顶联合区的偏侧化大脑机制参与了复杂的社会和道德推理，例如将信念归因于他人。基于这一证据，我们对 3 名前切除和 3 名完全胼胝体切开患者以及 22 名正常受试者进行了一项推理任务测试，该任务要求进行口头道德判断。所有 6 名患者的判断主要基于行为的结果，而不考虑行为者的信念。完全和部分胼胝体切开患者的表现相似，表明正常的道德判断需要信息在大脑两半球之间的充分整合，而这一过程受到右侧颞顶联合区和右侧额叶过程的关键支持。
