I am glad to attend #CNS2026 in beautiful VancouverπŸ‡¨πŸ‡¦! I will present my work on action planning in visual working memory. In this project, we focus on the factors leading motor planning such as selective attention, affordances and task requirements. Meet me at the Poster Session B (B38)!

Can you trust effect size estimates from your Bayesian sequential design / optional stopping sampling plan? Yes, you can!

In this simulation study, I show that effect size estimates from samples obtained via optional stopping with Bayes Factors are unbiased

Excited to share our paper (with @jzacks.bsky.social), now out in JEP:LMC!

Event boundaries sometimes disrupt temporal order memory in list-based paradigmsβ€”but what happens in narratives with more complex structures that better resemble real life?

Ever since the last big update that overhauled the interface at OSF the entire site runs poorly overall. Very long load times, timeouts for no clear reason, and weird errors. Seems like they should just roll the whole thing back to the previous version that worked.

I've got a bunch hosted on OSF with data keys (e.g. Ricker, Souza, & Vergauwe 2023, osf.io/bv6fh/overview). I'd be happy to have you include them if you are interested but don't have the time to reformat/rekey everything.

Claude Opus 4.6 is a surprisingly huge jump for a .1 upgrade. I've been astonished by how independently it can work and in the past month it has substantially helped me in projects in a way that I would absolutely think deserves co-authorship if it were a human collaborator.

Excited to share this work! The consistent lack of cue-driven proactive control challenges assumptions about our ability to readily deploy top-down control. We rule out S-R mappings, task pace and task difficulty as explanations, while showing that implicit, experience-driven control remains intact.

New preprint! We mapped out how β€˜diffuse’ predictions affect neural representations. We show predictions reshape the geometric layout of the neural representations by compressing the representational spread and stabilize the neural code by reducing the neural variance during memory encoding.

Can We Process Information Without Encoding It into Working Memory?

Our findings with @gidon-frischkorn.bsky.social and @koberauer.bsky.social suggest that processing entails encoding. Task-irrelevant information enters working memory during processing, impairing memory for relevant information.
