Cognitive Humor Processing in the Russian and English Internet Meme Chatting: EEG Study
摘要
This study deals with the neural correlates of internet meme perception using EEGs with a focus on prefrontal brain regions associated with complex cognitive and emotional processing. Twenty-one adult subjects watched memes and control stimuli with congruent and incongruent text-image pairs presented sequentially to isolate the periods of cognitive insight. Wavelet analysis revealed a specific pattern of brain activity around the fifth second of stimulus presentation—approximately one second after the image onset—within the alpha (11–14 Hz) and beta (22–28 Hz) frequency bands. This activity was localized in both the orbitofrontal and dorsolateral prefrontal cortices and was significantly noticeably more manifested for memes than for control stimuli. These results suggest that memes trigger neural responses associated with insight and semantic reinterpretation. Additionally, a language-dependent effect was observed: memes in Russian evoked greater dorsolateral prefrontal activity, while English memes entailed stronger orbitofrontal activation. These findings indicate that meme comprehension activates distinct neural mechanisms depending on the linguistic and cultural context of the viewer.
