This was such a joy!!! In this work, the brilliant @fridaprintzlau.bsky.social demonstrates the core features of VWM representations, namely its dynamicity and flexibility. TLDR: VWM dynamically shifts its representational geometry during maintenance depending on its task demand! What an ART!

New draft: "Decline effects, statistical artifacts, and a meta-analytic paradox". In this manuscript I show how a common practice in meta-analysis (eg the 2015 Open Science Collaboration) creates artifactual signatures of poor scientific behavior. PDF: raw.githubusercontent.com/richarddmore... 1/x

🚨New paper altert🚨 As a synthesis of my PhD research, we revisited the prevailing assumption about the mechanisms underlying repetition learning, and re-evaluated these assumption in light of recent findings. Now out in Perspectives on Psychological Science: doi.org/10.1177/1745...

"Repetitions lead to better memory." Sure - but how? Our new paper led by former lab member @philippmusfeld.bsky.social shines new light on this question, and challenges some longstanding assumptions. Now published in Perspectives on Psychological Science. journals.sagepub.com/doi/10.1177/...

The ADAM lab is hiring a Research Specialist to join us! This role involves conducting human subjects research (EEG experiments on attention + working memory) and assisting with the execution and administration of ongoing projects. Job posting: emdz.fa.us2.oraclecloud.com/hcmUI/Candid...

Make it your New Year resolution to add a #workingmemory dataset to OpenWMData so that we can curate our field's precious data, start testing theories and benchmarking models across datasets, conduct secondary analyses and meta-research using the data itself, and help me feel like I'm, like, alive.

Finally, @bjoernhommel.bsky.social's and my paper introducing the SurveyBot3000 is officially out in AMPPS. It's a fine-tuned language model that guesstimates correlations between survey items from text alone. Not perfectly, but useful for search, for example. journals.sagepub.com/doi/10.1177/...

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...

New paper out on value-based prioritization in visual WM. We used hDDM to account for speed/accuracy tradeoffs and isolate memory benefits from perceptual/motor benefits. We see perceptual/motor contributions suggesting that prioritization benefits are not purely mnemonic. Link: rdcu.be/eTUIm

Big news from the lab today: @joschadutli.bsky.social has officially defended his PhD! 🎉 We’re grateful to @aidanhorner.bsky.social for serving as external examiner and as Joscha’s supervisors we @leabartsch.bsky.social and @koberauer.bsky.social are incredibly proud—congrats, Joscha!

It was great having you @aidanhorner.bsky.social ! Thank you for serving as the external examiner on the defense committee of my (former!!) phd student @joschadutli.bsky.social ! Big congrats to Dr. Dutli!!

Is WM a gateway to LTM? In this registered report we find that higher WM load rarely impairs LTM encoding - suggesting WM capacity is not a bottleneck for forming LTM traces. @as-souza.bsky.social @edamizrak.bsky.social @cognition-zurich.bsky.social psycnet.apa.org/record/2026-... [1/3]

Do you have an open working memory dataset and want it to be findable and reused? You can now add it to the Open WM Data Hub: williamngiam.github.io/OpenWMData! The collection of datasets tagged with useful metadata is steadily growing thanks to a small team of volunteers!

Thank you to everyone who came to the symposium! I'm also grateful to the people who have chatted to me about my talk on building a formal cognitive model that fits for the latent representation to then link to neural representation similarity.

In our new paper in Psychology and Aging, @koberauer.bsky.social, @leabartsch.bsky.social, and I investigated age differences in the Hebb repetition effect, and show that chunk formation is largely preserved in old age. Check it out here: psycnet.apa.org/record/2026-...

PS is excited to announce the launch of "Individual Differences in Cognition” (IDIC), an open-access journal on research in cognitive psychology, science, and neuroscience. Co-Editors-in-Chief are Andrew R.A. Conway & Michael J. Kane. Manuscripts accepted this spring. More information coming soon!

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

Belated but hopefully still exciting #rstats news: bridgesampling version 1.2-1 has just arrived on CRAN: cran.r-project.org/package=brid... We now finally provide cmdstanr support (!) plus Monte Carlo Standard Error (MCSE), both thx to Giorgio Micaletto and @avehtari.bsky.social!

3 Presentations from my lab at Psychonomics this week! Friday (Nov.21), 3:30-5:30 Working Memory I Does Reward-Based Prioritization Function through the Same Mechanisms in Verbal and Visual Working Memory? TIMOTHY J. RICKER, University of South Dakota, JOSHUA SANDRY, Montclair State University

The academic publishing system is so rotten, it must be completely dismantled. Not partially, and not improved. Dismantled and rebuilt from the ground up. When I tell non-academic friends how it all works they stare at me in disbelief. Not only that it exists, but that we still allow it to.

This is alarming. It’s not only about the struggle an individual researcher has when all his public records suddenly disappear. It’s about trust in a reliable open archival system that we need to continue the rise of open and transparent science. Highly recommended read!

A recent redesign of OSF by @cos.io led to widespread access failures. What began as a few broken download links became for me a total disappearance of eight years of DOI-registered work. What happened, how was it resolved, and what it reveals about trust and infrastructure in open science

Please repost! I am looking for a PhD candidate in the area of Computational Cognitive Neuroscience to start in early 2026. The position is funded as part of the Excellence Cluster "The Adaptive Mind" at @jlugiessen.bsky.social. Please apply here until Nov 25: www.uni-giessen.de/de/ueber-uns...

Is anyone else experiencing significant issues (lags, not loading) with OSF (@cos.io) since the interface update?

What annotations / metadata do you wish was included with every #cogsci dataset (especially #workingmemory folks 👀)? My current list includes the experiment task, stimulus, level of data (trial-, subject-, or group-level), format, and whether analysis code is provided. Any more?

Tomorrow afternoon I'll be presenting my symposium talk at #ESCoP2025 titled "Meaningful and familiar stimuli support visual working memory for simple features"! See you there!

Presenting my talk at #ESCOP2025 today at 4pm in the symposium "Cognitive Mastery in Play: From Board to Digital Games as Models of Expertise" in LT2 🎮🎲 Hope you see you there!

Exciting #rstats news for Bayesian model comparison: bridgesampling is finally ready to support cmdstanr, see screenshot. Help us by installing the development version of bridgesampling and letting us know if it works for your model(s): pak::pkg_install("quentingronau/bridgesampling#44")

Now out in JEP:G! We (@fridaprintzlau.bsky.social & @keisukefukuda.bsky.social ) resolve inconsistent attentional protection in WM by addressing discrepancies in cueing. Upshot: Attention changes how perception biases memory, but *not* how memory biases perception! doi.org/10.1037/xge0...

🚨 New paper with @leabartsch.bsky.social and Agnes Rosner! Our results show that location information is similarly reactivated for rehearsal and visual imagery. #workingmemory #eyetracking Out now in @jcgntn.bsky.social Read more: journalofcognition.org/articles/10....

New paper alert🚀 Episodic memory is structured by event boundaries—moments of critical change. The common view suggests that prediction errors drive them—but is that true? We show that contextual stability, not prediction errors, is the key driver of segmentation. link.springer.com/article/10.3...

🚨 Calling all colleagues who work on #workingmemory and #aging 🚨 Do you have any unpublished data on age differences in WM? 👴 👵 🧠 🌨️ We're working on a BIG meta-analysis, and I'd love any and all data that are currently not "out there" for us to find! 🔬 🤓 Please repost for reach, thanks! 🔁 😁

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. 🔗 osf.io/preprints/ps...

New Preprint with @edamizrak.bsky.social! Performance in immediate memory tasks reflects a flexible mixture of contributions of #workingmemory and LTM. Distraction disrupts WM, while PI impairs retrieval from LTM; when both are in play, performance depends on the relative reliability of each system

Dear WM ECRs across the globe, please consider joining the BEST ONLINE conference ever!

Honey, we fixed Signal Detection Theory (SDT)! In this preprint, Constantin Meyer-Grant, David Kellen, Sam Harding, and I critically evaluate the (unequal-variance) Gaussian SDT model in recognition memory and pursue the Gumbel-min model as a principled alternative: doi.org/10.31234/osf... 🧵

This is now published in the Journal of Mathematical Psychology! www.sciencedirect.com/science/arti... with @annalschubert.bsky.social, @gidon-frischkorn.bsky.social, and Klaus Oberauer

Finally, Ven Popov's & my paper introducing the Bayesian Measurement Models (bmm: venpopov.github.io/bmm/) R package is published in Behavior Research Methods: rdcu.be/ehKtv In the paper we show how to use bmm for fitting mixture models for visual #workingmemory tasks.

Very happy to share this preprint, a collaboration with two academic role models of mine @evievergauwe.bsky.social and @as-souza.bsky.social - I am very honored to be able to work together with such brilliant, strong women 🤩
