Want to decompose your categorical recall data into latent memory sources?

After hundreds of studies on the retro-cue effect in working memory, we thought that we understood what caused it. Not quite - check out our new paper:

We have a new PhD position at the University of Zurich to work on visual working memory. For more info see here:

Two traditions in action control research - BRAC and procedural WM - often talk past each other.
This latest review from members of our lab and colleagues from the BRAC community connects them conceptually and computationally, showing how procedural WM can reproduce key BRAC effects.
A sneak peak into hallway and lunch break discussion that we have at our lab:
@gidon-frischkorn.bsky.social, @joschadutli.bsky.social, @philippmusfeld.bsky.social, and @koberauer.bsky.social wrote up what we think is a reasonable workflow for specifiying priors in GLMs.

New work from our lab: Can psychometric methods alone tell us what cognitive tasks measure?
@gidon-frischkorn.bsky.social, Ricardo Rebmann & @koberauer.bsky.social argue no – and show how computational models can do what correlations between tasks cannot. 🧵👇

New work from members of the Cognition Lab Zurich!
@chenyuli.bsky.social, @gidon-frischkorn.bsky.social & @koberauer.bsky.social tested whether information can be processed without entering working memory.
Results suggest that processing brings even task-irrelevant information into working memory.
New #bmm release by @gidon-frischkorn.bsky.social and @venpopov.bsky.social. If you work with response time data in R, this makes hierarchical Bayesian estimation considerably easier. Details in the thread below. #rstats #cognitivemodeling

Can we remove information from working memory and still maintain it in the long term - or the other way around? It turns out to be difficult. If you want to know more, check out our new paper:

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, individ...
A new #bmm release is available on #CRAN. With this version, #bmm now covers basic response time models. This release contains three new models plus several usability features. Here's what's in it 🧵

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.
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.

New preprint with @chenyuli.bsky.social!
We wrote a hands-on tutorial for applying the Memory Measurement Model (M3) to categorical recall data using the #bmm R package. It contains four examples, complete R scripts, and a parameter recovery workflow.
Preprint: osf.io/preprints/ps...
I wrote up something that's been in my head for a while: psychometric methods alone can't tell us what cognitive tasks and their indicators measure.
Correlating indicators across tasks is circular when constructs are defined by those same correlations.

@philippmusfeld.bsky.social , @joschadutli.bsky.social, @koberauer.bsky.social and I wrote up the result of three years of in lab discussions on setting priors in GLMs.
Hope some of you find the proposed workflow and our recommendations helpful!
