🌈 New preprint! With Sage, Melissa, and Kia (@dynacog-lab.bsky.social, @scenegrammarlab.bsky.social, @kianobre.bsky.social), we explore how attention is divided across external perception and internal working memory - revealing a dynamic trade-off between these two domains. doi.org/10.64898/202...

If information accumulates in WM, neural markers of WM load should gradually increase across items within an event If information is reactivated at boundaries, WM load should increase when a new event begins — reflecting reinstatement of the preceding event.

The results supported boundary-triggered reactivation: alpha-band suppression increased following events Evidence for accumulation was more limited: CDA gradually increased across items within an event, but alpha-band suppression did not

Working memory has long been thought to support segmentation, but how it does so remains unclear. Using two EEG indices sensitive to working-memory load (contralateral delay activity (CDA) and alpha-band suppression), we tested two possibilities: accumulation vs. reactivation

Can you make your life feel “longer” in retrospect? Add a dose of change and novelty in the present to later expand memories of your past. Excited to share our work on how dopamine-related processing bends memory to reflect the passage of distinct events. newsroom.ucla.edu/releases/can...

newsroom.ucla.eduCan dopamine bend time to shape memory?The brain may use dopamine to expand time between distinct events, enabling us to remember unique episodes.

Happy to share that I will give a colloquium talk at the Heymans Institute for Psychological Research, University of Groningen, on June 2 I will present my work on how experiences are segmented into meaningful events, and how contextual stability and working memory contribute to this process ✨

Under stress, two things happened in the hippocampus: 1) Less reactivation of the prior related memory during new learning 2) Greater neural dissimilarity between overlapping events To put it another way, stress pushed related memories apart instead of pulling them together.

In collaboration with @monicarosenb.bsky.social , we showed that individual diffs in LTM encoding is uniquely predicted by inter-electrode correlations even controlling for working memory abilities. This suggests that WM & LTM encoding are separate abilities coded by different neural signatures! 1/n

Our results support boundary-triggered reactivation as the primary mechanism, with only moderate evidence for continuous accumulation. These findings suggest that WM mainly supports event organization by reinstating recent information at moments of event transition

Super excited to see this out in the world!

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. Link: osf.io/preprints/ps...

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.

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! 😊
