“得到一个笑话”总是需要解决一个明显的不协调，但特定的认知操作需要根据笑话本身的性质而变化。以前的研究已经确定了认知和情感过程的主要神经相关性，这些过程通常被称为对幽默的反应，但很少有人对理解特定笑话类型所需的不同认知操作的基础进行研究。本研究探讨了成功理解三种笑话类型所需的认知过程的神经相关性：桥接推理笑话（BJ），夸张笑话（EJ）和歧义笑话（AJs）。对于所有类型的笑话，左dlPFC似乎支持共同的认知机制，如脚本转换，而vACC与情感欣赏。颞顶叶（TPJ和MTG）与BJ相关，表明这些区域参与了“心理理论”处理。额顶叶（IPL和IFG）与EJs和AJs相关，这表明它支持执行控制过程，如从情景记忆中提取，自我意识和基于语言的解码。对口头笑话的社会情感欣赏与眶额皮质、杏仁核和海马旁回的活动有关。这些结果可以更精确地解释支持理解不同类型幽默所需的特定认知操作所需的神经过程。
‘Getting a joke’ always requires resolving an apparent incongruity, but the particular cognitive operations called upon vary depending on the nature of the joke itself. Previous research has identified the primary neural correlates of the cognitive and affective processes called upon to respond to humor generally, but little work has been done on the substrates underlying the distinct cognitive operations required to comprehend particular joke types. This study explored the neural correlates of the cognitive processes required to successfully comprehend three joke types: bridging-inference jokes (BJs), exaggeration jokes (EJs), and ambiguity jokes (AJs). For all joke types, the left dlPFC appeared to support common cognitive mechanisms, such as script-shifting, while the vACC was associated with affective appreciation. The temporo-parietal lobe (TPJ and MTG) was associated with BJs, suggesting involvement of these regions with ‘theory of mind’ processing. The fronto-parietal lobe (IPL and IFG) was associated with both EJs and AJs, suggesting that it supports executive control processes such as retrieval from episodic memory, self-awareness, and language-based decoding. The social-affective appreciation of verbal jokes was associated with activity in the orbitofrontal cortex, amygdala, and parahippocampal gyrus. These results allow a more precise account of the neural processes required to support the particular cognitive operations required for the understanding of different types of humor.
