脑岛被认为与厌恶有关。然而，在先前的研究中，后岛叶（PI）和前岛叶（AI）在道德厌恶中的作用尚未明确分离。在这项功能性磁共振成像研究中，参与者使用与不同类型的行为主体（母亲和陌生人）的轻度道德违规相关的句子来评估厌恶程度。 PI 对陌生智能体的激活显着高于对母体智能体的响应。相比之下，AI 对母代理的激活明显高于对陌生人代理的响应。这些数据表明，PI 和 AI 之间存在明显的功能分离，其中 PI 比 AI 更多地涉及初级道德厌恶，而 AI 比 PI 更多地涉及次级道德厌恶。我们的研究结果为理解具身认知的原理提供了关键证据，并特别证明了高级道德厌恶是通过具身图式过程的心理构建方法建立在更基本的厌恶之上的。
The insula is thought to be involved in disgust. However, the roles of the posterior insula (PI) and anterior insula (AI) in moral disgust have not been clearly dissociated in previous studies. In this functional magnetic resonance imaging study, the participants evaluated the degree of disgust using sentences related to mild moral violations with different types of behavioral agents (mother and stranger). The activation of the PI in response to the stranger agent was significantly higher than that in response to the mother agent. In contrast, the activation of the AI in response to the mother agent was significantly higher than that in response to the stranger agent. These data suggest a clear functional dissociation between the PI and AI in which the PI is more involved in the primary level of moral disgust than is the AI, and the AI is more involved in the secondary level of moral disgust than is the PI. Our results provide key evidence for understanding the principle of embodied cognition and particularly demonstrate that high-level moral disgust is built on more basic disgust via a mental construction approach through a process of embodied schemata.
