Below, three statistics are displayed: 200+ chapters, 60+ countries, 100k+ members. A tagline reads "Promoting gender diversity in the R community worldwide." The bottom bar shows rladies.org, #RLadiesIWD2026, and #IWD2026.

We Are R-Ladies

200+ chapters. 60+ countries. 100,000+ members.

Since 2012, we've been promoting gender diversity in the R community — building a global network of R leaders, mentors, learners, and developers.

This is who we are.

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.

We are: @isabelcourage.bsky.social, @hannahdames.bsky.social, David Dignath, Christina U. Pfeuffer, Moritz Schiltenwolf, Andrea Kiesel, and @koberauer.bsky.social

Bindings for Action: Bridging the Gap Between Theories of Procedural Working Memory and Action Control Research | Journal of Cognition

In a new review paper in @jcgntn.bsky.social , we compare the #BRAC framework with procedural #WM theories.

We clarify where they agree & diverge, and demonstrate with simulations that procedural WM can capture hallmark BRAC effects.

"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.

If you @solomonkurz.bsky.social are interested in the details of the translation we implement you can extract either the brmsformula and family from a fit object or also extract the stancode from any model you specify.

I also thought about „refcat = NA“! Nice to see that this provides tha proper solution.

This is also what we implement when translating multinomial measurement models into brms in the bmm R package: venpopov.github.io/bmm/articles...

Process-oriented intelligence research: A review from the cognitive perspective Despite over a century of research on intelligence, the cognitive processes underlying intelligent behavior are still unclear. In this review, we summ…

With a more conceptual approach to this in cognitive individual differences research I try to advocate for a similar approach bridging formalized modeling with traditional psychometric work: www.sciencedirect.com/science/arti...

Looking forward to where the field is heading in the next few years 🤓

Again more interesting work on bridging #psychometrics with #experimentalpsychology! Looking forward to reading this preprint and it is awesome to see that more and more people are working at the intersection of psychometrics and experimental psychology!

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!

Andy Conway and I are honored to serve as inaugural co-Editors of this new Psychonomics journal, focused on the rigorous study of individual differences in cognition. Please spread the word to potentially interested colleagues; we hope that you will send us your best relevant work!

Good news for all those of us who plan to grow old: Some forms of learning do not decline in old age. Our new paper in Psychology and Aging shows equivalent learning rates in older and younger adults in chunk learning, tested through the Hebb repetition effect.

Memory researchers have known this: If we leave more free time between one study item and the next, memory is better. This is true for WM and LTM - but is it so for the same reason? Probably not. If you want to know more, have a look at our new paper in JEP:General: psycnet.apa.org/record/2026-...

The Cognition Lab @ University of Zurich is on Bluesky! Follow us for updates on new papers & preprints, conferences that lab members attend & other news around research on #workingmemory, #attention, and #longtermmemory.

Simonsohn has now posted a blog response to our recent paper about the poor statistical properties of the P curve. @clintin.bsky.social and I are finishing up a less-technical paper that will serve as a response. But I wanted to address a meta-issue *around* this that may clarify some things. 1/x

3/3 My personal highlight of #ESCOP2025 was becoming this year‘s #WomWom research fairy! 🧚‍♂️ Thanks again to all my fellow #WomeninWorkingMemory. It means a lot ❤️

The next installment (October 8th) of our OPAM Training Workshop series will feature Dr Caro Hautekiet (of Vrije Universiteit), who will be discussing pre-registration and registered reports. Visit this page for info on all our (free!) workshops: www.opamconference.com/workshops-su...

It was an absolute pleasure and so much fun to teach this course at #ESCoP25! Huge thanks to my co-organizers, all the participants, and the ESCoP team for making it such a fantastic experience!

Yes, this was a really great experience! Thanks for @cvonbastian.bsky.social and @vmloaiza1.bsky.social for asking us to do this as part of #ESCOP2025! And if you are interested in having a similar workshop for your PhD Programm or similar, feel free to reach out!

With less than week until #ESCOP2025, we're super excited to kick-off our conference with something truly special - an Algorave! 🤩 (1/12 👀)

Hey #memory folks, check out this new preprint by @joschadutli.bsky.social , @koberauer.bsky.social, and @leabartsch.bsky.social showing that elaboration benefits are likely driven by aiding in establishing efficient retrieval cues.

Applications are invited for a Postdoctoral Position (80%) at the Cognitive Psychology Unit, Department of Psychology, University of Zurich. The ideal start date would be January 1st, 2026 but could be somewhat earlier or later. The position is for initially 3 years, with possible renewal for another 1.5 years. The successful applicant will work with the head of the Cognitive Psychology Unit, Prof. Dr. Klaus Oberauer, and the Cognitive Psychology team. The post involves research and teaching (one course per semester). Research at the Zurich Cognitive Psychology Unit focuses on capacity limits of cognition, in particular working memory, long-term memory, and attention, which we investigate with experimental, individual-differences and aging studies and computational modeling. For further information see: https://www.psychology.uzh.ch/en/areas/nec/allgpsy.html We offer: - An attractive research environment with close collaboration within the team - Excellent lab infrastructure - Salary according to Cantonal regulations We expect: - a PhD in psychology or a related discipline - experience with experimental research - excellent method knowledge and skills - very good command of English - interest in pursuing an academic career in cognitive psychology In addition, it would be desirable if you had: - experience with publishing in international journals - programming skills - experience with mathematical / computational modeling Please send applications including your CV and motivation letter no later than September 10, 2025 electronically as a single PDF to: Michaela Oestmann, michaela.oestmann@psychologie.uzh.ch For questions about the position please contact Klaus Oberauer, k.oberauer@psychologie.uzh.ch

🚨 PostDoc Opening 🚨 The lab of Klaus Oberauer is looking for a new postdoc, starting end of this/beginning next year. Research focus is #cognition, #workingmemory, #methods and #computationalmodeling or anything in that direction. I cannot highlight ENOUGH how great it is to work in this lab 🥰🤓

Thanks for creating this! Would be great if you would add me 😇

We had some weird effects where the evidence for an interaction was ambiguous with dummy coded factors, but with the same data and sum-to-zero coded factors there was strong evidence for an interaction based on Bayes Factors.

Yes, the priors are typically set in the effect coefficients. Thus, dummy coding changes the prior predictive for different group means. As the reference group would only get the intercept prior, whereas an effect group would get intercept prior + effect prior.

For frequentist analysis the coding might be more of a convenience choice, depending on which coefficients are easier to interpret for you. But in Bayesian analyses the coding can make a big difference for the inference you draw. At least when using Bayesian Factors & prior predictive comparisons.

For details on the Memory Meausurement Model (M3) see this article: venpopov.github.io/bmm/articles...

And for all #decisionmaking researchers, you can easily use the model for any multinomial data assuming continuous activation strengths underlying the competitive selection among candidates
