Mathematical ‘random tree model’ reveals how we store and recall narratives

Scientists have developed a new mathematical model showing how the human brain stores narratives using tree-like structures. The model suggests that memory organizes stories hierarchically, with broader summaries near the "root" and more detailed events branching out. Researchers tested the theory through recall experiments with over 100 participants using various narratives. The findings could have implications for understanding human cognition and how people make sense of experiences and events.
