1/ How do we sustain mental continuity in the face of interruption? @xianl-explorer.bsky.social found that, while people listen to a story, posterior medial cortex expresses a slowly evolving "background" representation of the story's context, which survived through silence and interfering tasks.

How do keep a narrative active in our mind despite interruptions? The default mode network can maintain a representation of an interrupted story over a delay, even when the delay is filled with a demanding task. This representation is strikingly transformed from the initial experience!

Cortical and Hippocampal Pathways to Mental Continuity
How do people preserve mental continuity when tasks are interrupted? One established pathway runs through the hippocampus, which stores snapshots of our mental context for later reinstatement. We prop...

In New York for #CCN2026! I’ll be presenting a poster on human-LLM alignment in narrative causal reasoning. If you’re interested in memory, narratives, AI, cognitive neuroscience, or just want to chat about research, postdocs, life, or exploring NYC, come say hi. Always happy to meet new people!

Excited to share that my first-ever first-author paper (w/ @atabk.bsky.social @AngeliqueDelarazan @zreagh.bsky.social) is now out in PNAS! Building a story to link two objects boosts associative memory and inference, but not memory for the objects themselves. www.pnas.org/doi/10.1073/... 🧵

Active linking through narratives facilitates associative inference | PNAS
In daily life, we often draw inferences about novel associations from prior experiences. This ability, associative inference, is thought to be a ke...

New work on agency and memory by @xianl-explorer.bsky.social, Janice Chen, myself and others! Using choose-your-own-adventures, we found that agency doesn’t always improve memory. Instead, agency personalized memory ❄️ ❄️ — even when people read the same text. www.nature.com/articles/s41...
A schematic image of all story paths in a choose-your-own-adventure story. Two paths are highlighted, diverging in the beginning my and end, but overlapping in the middle portion of the story.
