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.

New content: Rodriguez, A., Musfeld, P., & Bartsch, L. M. (2025). The Flexibility of Working Memory in Drawing on Episodic Long-Term Memory Representations in Serial Recall. Journal of Cognition, 8(1): 40, pp. 1–26. DOI: doi.org/10.5334/joc.... #psychscisky

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

Super excited to share that Ven Popov & me published a new release of the #bmm R package: venpopov.github.io/bmm/

We have added the Memory Measurement Model for categorical #workingmemory tasks to the package!

Apart from that there are some minor fixes to already implemented models and functions.

For anyone who ist familiar with R package structure I actually think it’s a very neat way to include a code book for your data and also adequately document any functions you might use.

If there’s is any questions with respect to the analysis feel free to reach out ☺️

Thank you so much for this positive feedback ❤️ And this is the first paper where I have used the R package structure to document and organize the code. I really enjoyed the features of roxygen documentation for datasets and analysis.

🚨 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! 🔁 😁

Bottom line: Various SEM can fit well yet tell different stories — highlighting the model-specification challenge. Best fix from my perspective? Refine indicators using theoretically grounded parameters from formal measurement models: doi.org/10.1016/j.in...

The original paper claimed that N-Back and Complex Span tasks measure different aspects of WMC and that N-Back tasks show stronger relationships with fluid reasoning. Some re-analysis showed the a single factor model fits better to the data and shows a correlation of .97 between the WMC & Gf.

In this study, we investigated the origin of the retro-cue benefit and observed that performance benefits because the cue protects against memory decay and test-display interference 😎 #workingmemory
