Excited to share the publication of our work which explores the application of LLMs in event segmentation and memory research.
For researchers interested in applying these validated methods, an open-source module is available on GitHub (github.com/ryanapanela/EventRecall).
Our new preprint is out!
Using a continuous-report paradigm, we show that divided attention reliably disrupts long-term memory retrieval by reducing accessibility—not precision.
Two experiments + mixture modeling + TCC.

This is so helpful!
Just finished my last class of the semester🎉Reminded of how much I love teaching this academic writing class for grad students. We focus on improving our writing but also reducing anxiety and becoming a more consistent & productive writer
Some of the students favorite writing tips/learnings below:
Beyond Likert scales: We introduce a novel self-report method for measuring RHI strength using inverse multidimensional scaling. Ownership scores emerge from arrangements of bodily experiences in psychological bodily space as distances between RHI and baseline cases of no and full body ownership.
New preprint alert!
Cognitive maps are flexible, dynamic, (re)constructed representations

A woman (me) standing next to a research poster titled, “Do Individual Differences in Inhibitory Control and Working Memory Updating Predict Effect of Errors During Learning on Recall?”
First Psychonomics in the books! Heading home full of inspiration and excitement after 4 days of fascinating talks, poster sessions, and conversations. Thanks to everyone who shared their research, insights, and questions, and especially to the organizers who made it all happen! #psynom25
Super excited to share my first preprint with Katherine Duncan and Morgan Barense (@barense.bsky.social) -- "Memory strength at reactivation, not memory age, governs prediction error driven updating of naturalistic event memory"! 🧠🎉https://osf.io/preprints/psyarxiv/q9rkn_v1
I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com
A new preprint "Anxiety Modulates Event Segmentation" with @yaelniv.bsky.social and colleagues!

All publicly available. Looks like an amazing new histology-based human probabilistic atlas and parcellation tool.

I wrote a thing on episodic memory and systems consolidation. I hope you all enjoy it and/or find it interesting.

Our experience of time is powerfully shaped by boundaries between events (i.e., going from one meeting to the next). But what about time *within an event*? In new work, we find reliable distortions of time based on internal event structure (e.g., beginnings, middles, and ends)! tinyurl.com/n8mn2sn7

Columbia Psych is hiring *two* junior faculty in Cognitive Science/Neuroscience this year! If you work on cognition (broadly defined), submit your application materials as soon as possible (review starts Nov 1). If you have questions you can reach out to me by email! apply.interfolio.com/175428
I’m excited to share my recent preprint on a neural network model of free recall that learns multiple memory strategies including the memory palace!

🧠🚨 How does the hippocampus transform the visual similarity space to resolve memory interference?
In this new preprint, we found that the hippocampus sequentially inverts the behaviorally relevant dimensions of similarity 🧵

Out now in @nathumbehav.nature.com! We applied graph theoretic analyses to fMRI data of participants watching movies/listening to stories. Integration across large-scale functional networks mediates arousal-dependent enhancement of narrative memories. Open access link: rdcu.be/eKKAw
You learn better when you test yourself on an answer before you study it? Even more counterintuitive, our findings showcase that there is not one direct mechanism to this effect.
Thank you @charan-neuro.bsky.social , @xiaonanl.bsky.social , and @jameswardantony.bsky.social !

Congrats, excited to read!
Our new paper explores an analogy between representations of objects and representations of events, finding that similar illusions arise for both! Check it out 👇
Next up, from @atabk.bsky.social and @wouterkool.bsky.social: Free recall is shaped by inference and scaffolded by event structure. In sum, Ata stuck hidden (and shifting) rules into a word list learning task, creating "events" that influenced the structure of recall.

I'm a behind on shouting out new papers!
From Angelique Delarazan: Narrative Coherence Warps the Timeline of Recalled Naturalistic Events. In sum, when recalling stories, people systematically deviate from temporal organization to follow the narrative threads.

How do the brain’s event representations change as we gain familiarity with an experience?
Brain regions’ representations can become coarser or finer as event familiarity increases. Fine-tuning predicts memory recall.
Excited to share this work with Narjes Al-Zahli & @chrisbaldassano.bsky.social!
Excited to read this!
Check out a new preprint from Adi, postdoc working with me and Jeff Zacks. I’m *extremely* excited to finally, officially get this out into the world 🙂
the rare paper in which authors can describe their own work as "strange," "trippy," "crazy," or "bonkers" 😂
Indeed lol
