In sum: It’s not surprising changes, but contextual stability, that determines how we segment continuous experience into discrete events.

Across three experiments, we manipulated contextual stability while keeping prediction errors constant. In a separate experiment, we manipulated prediction errors while holding the context stable. To assess event segmentation, we used temporal distance and temporal order tasks.

Across 4 experiments, we both manipulated contextual stability and prediction error. Findings consistently showed that contextual stability, not prediction error, better accounts for how people segment continuous experience into memory units.

Our paper is accepted in Psychonomic Bulletin & Review! 🎉
We challenge the idea that prediction errors drive event segmentation, showing that contextual stability plays a more dominant role in structuring episodic memories.

I’ll share findings from my recent research — which has been accepted for publication in Psychonomic Bulletin & Review — on how contextual stability, rather than prediction errors, might play a more dominant role in structuring episodic memories. Hoping to see you there! 😊

First time in #VSS2025 and it was a wonderful experience both academically and socially 🌸

New from our lab: your brain doesn’t just remember time - it bends it.

We show that the dopamine system responds to natural breakpoints in experience, and this relates to more stretched memories of time. Blinking also increases, signaling encoding of new memories.

Dopaminergic processes predict temporal distortions in event memory
Our memories do not simply keep time - they warp it, bending the past to fit the structure of our experiences. For example, people tend to remember items as occurring farther apart in time if they spa...

Our study examined how working memory (WM) supports event segmentation—whether it accumulates information during event comprehension or reactivates items at boundaries. We found evidence for both, suggesting that WM plays a functional role in both processes

Excited to share a new study from ACME Lab on how emotional processing shapes event segmentation! It shows that both negative stimuli and their down regulation impact how events are segmented in memory.

Preprint update! We tested roles of contextual stability and prediction error in event segmentation, independently manipulating each factor in 4 experiments. We found contextual stability as the primary driver - challenging the event segmentation theory

Standing up for science is standing up for truth, reason, and wellbeing. So proud of my lab and colleagues for coming out to the march today!

Thanks to the organizers of the 10th International Symposium on Brain and Cognitive Science for a fun meeting. Burhan Bağlar, Sinem Subaşı, and Yaren Kaynar did a wonderful job presenting their work despite being swamped with final projects and presentations. Well done! See our posters below.

Excited to share our new review paper! Episodic memories comprise segmented units. The role of working memory (WM) in such segmentation is implemented but not sufficiently studied. We explore the potential roles of WM and attention in event segmentation. www.sciencedirect.com/science/arti...

Many thanks to @erengunseli.bsky.social for providing great mentorship, and to Zeynep Adıgüzel and Bilge Uysal for their support and roles in developing super cool ideas ✨

We also propose possible underlying mechanisms and experimental predictions to test these models

📣New paper alert! We discuss the role of working memory in event segmentation. We propose accumulation and reactivation models that explain how working memory may be accumulating memoranda within events and reactivating memoranda at event boundaries

New paper alert! Congrats to Yağmur D. Şentürk and Nursima Ünver for constructing a complex design & collecting 65 EEG datasets (each 4 hours)!🎉Our study reveals that switching to a new task rule triggers memory reactivation of previously learned items. authors.elsevier.com/a/1iIjT2VHY8...
