Based on feedback from modelbasedneuroscience.com just held in Amsterdam an update of the Dynamic Models of Choice software for Bayesian estimation of evidence accumulation models is available at osf.io/pbwx8. Thanks to everyone who attended!

Hey everyone! I wanted to let you know that our JASP Statistics how to guides for undergraduate stats are up at: osf.io/t56kg/ feel free to use them for course materials or yourself. You can also send me a note if corrections need to be made.

This new modeling allows you assess the ability to inhibit responses to difficult choices, I think it has potential to greatly expand measurement and understanding of cognitive control.

The next issue of Computational Brain and Behavior is now available: link.springer.com/journal/42113/… There is some really interesting new multi-disciplinary work in this issue. Keep an eye on Computational Brain & Behavior for highlights!

Surprising finding from new modeling dora.erbe-matzke.com/papers/Inhibit… that it is not traditional stop-signal RT that is linked to real world impulse control but rather failures to attend to the goal of stopping (see also dora.erbe-matzke.com/papers/Sz_APP_…)

Probability Density Approximation (PDA) lets you do full Bayes estimation for a model you can only simulate. This paper with Yi-Shin Lin in press at BRM explores CPU/GPU speed ups and tweaks to standard sampling needed to make it work tascl.org/uploads/4/9/3/…

Huge amount of work by Dora on a hard problem with an important lesson: recovering estimated parameters does not necessarily mean your model is identified!

Andrew Heathcote (@andrewheathcot8) 's Twitter Profile Photo

You can now use this approach to get Bayes Factors for any model implemented in DMC (osf.io/pbwx8/), just remember, think about your priors!

Our paper got published in PNAS this week! It's a cool study of big data from Lumosity's brain training platform. We learn about task switching, practice, and the effects of age: pnas.org/content/early/…

Stay tuned to the Computational Brain & Behavior account: in the next two weeks we will feature a different accepted paper each day! Many of them discuss the important topic of robustness and reproducibility in computational modeling of cognition.

Finally out after a long wait, a fast way to do Bayes for simulation only models, but also some cautions about the pitfalls ... link.springer.com/epdf/10.3758/s…

I'm thrilled to finally share our pre-print on using cognitive process modeling to address context independence violations in the ABCD Study stop-signal task! The culmination of over a year of work with @dora_matzke, @CharlotteCTanis and Andrew Heathcote...
