Modeling Brain Responses to Natural Conversation via LLM-Derived Informational and Relational Metrics

The project uses large language models (LLMs) and information-theory measures to quantify how people think in real conversations. The goal is to create a pipeline that quantifies informational content (the purpose of the utterance is to provide/inquire information) and relational content (the purpose is to build a stronger relational bond with the other speaker) in conversation utterances. Then, we will test whether these conversation features can predict which parts of the brain become active while people talk and listen in natural, everyday conversations. This work will help Princeton and the University of Toronto develop better, more realistic models of human communication and brain function, and will produce tools and analyses that can support future research in neuroscience and AI.
