Scott Morrison: Declare a climate emergency chng.it/MY68vfsX via @ChangeAUS

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 @AndrewHeathcot8...

New #AllThingsCognition podcast episode @lmickes interviews Andrew Heathcote @AndrewHeathcot8 on #gocrpi paper on predicting brief changes in workload wp.me/p8IxYp-1V1 wp.me/p8IxYp-1V1

Stay tuned to the @CompBrainBeh 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.

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/…

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…

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!

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!

Probability Density Approximation (PDA) lets you do full Bayes estimation for a model you can only simulate. This paper with @YiShinLin1 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/…

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_…)

@danielrlittle @AdamOsth @CLudowici @msvanarmy Luce 1986 book has an example of simple RT that’s only slightly right skewed. Mixtures can also do it, I have a PLoS Computational Biology analysing supposedly accuracy emphasis monkey data where there is a speed hump. Also occurs in timed responding indicating collapsing bounds

@AdamOsth @3rdincharge Great ABC satire on Australian “culture”

@3rdincharge So I’ve been living here for four years and don’t know this - what is Kim and Kath?

An upshot of living in Australia is never having to get a presidential alert on my phone.

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 @CompBrainBeh for highlights!

@AdamOsth Your in good company Jim Townsend did the same thing at an Au’s Math Psych in WA

I’m not really sure how this happened. I (properly) use a kettle about three times a day!

I’ve been living in Australia for four years and made the most American mistake this morning - I put the kettle on a lit stove. There was a lot of smoke and now my kitchen smells like burnt plastic.

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.
