Temporo-parietal and fronto-parietal lobe contributions to theory of mind and executive control: an fMRI study of verbal jokes.

Chan YC, Lavallee JP - Front Psychol (2015)

Bottom Line: 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 social-affective appreciation of verbal jokes was associated with activity in the orbitofrontal cortex, amygdala, and parahippocampal gyrus.

ABSTRACT
'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.

Common neural mechanisms of general joke processing. (Left) Commonly activated region of the left dorsolateral prefrontal cortex (dlPFC) in joke comprehension stage. (Right) Commonly activated region of the ventral anterior cingulate cortex (vACC) in joke appreciation stage. Bars show mean beta values of peak voxels for the left dlPFC (BA 9) and vACC (BA 32). Error bars represent SEM.

Figure 5: Common neural mechanisms of general joke processing. (Left) Commonly activated region of the left dorsolateral prefrontal cortex (dlPFC) in joke comprehension stage. (Right) Commonly activated region of the ventral anterior cingulate cortex (vACC) in joke appreciation stage. Bars show mean beta values of peak voxels for the left dlPFC (BA 9) and vACC (BA 32). Error bars represent SEM.

Mentions: A conjunction analysis of processing for bridging-inference (BJ-BS), exaggeration (EJ-ES), and ambiguity (AJ-AS) jokes revealed common regions in the left dorsolateral prefrontal cortex (dlPFC; presumably related to cognitive processing) and vACC (presumably associated with affective processing; Table 7 and Figure 5). Activation for the vACC spread to the midbrain (74 voxels), lentiform nucleus (486 voxels), putamen (376 voxels), and thalamus (273 voxels).
