Abstract Given the same external input, one’s understanding of that input can differ based on internal contextual knowledge. Where and how does brain represent latent belief frameworks interact with incoming sensory information to shape subjective interpretations? In this study, participants listened auditory narrative twice, a plot twist in middle dramatically shifted their interpretations story. Using robust within-subject whole-brain approach, we leveraged shifts neural activity between two listens identify where are represented brain. We considered terms its hierarchical structure, examining global situation models subcomponents–namely, episodes characters–are represented, finding they rely partially distinct sets regions. Results suggest our brains narratives hierarchically, individual elements being dynamically updated as part changing information.
