📢 NEW PREPRINT 📢 We show a metacognitive paradox (not blanket deficit!) in OCD: confidence is persistently lower, but fluctuations track evidence more tightly and are nearer Bayes-optimal. www.researchsquare.com/article/rs-7... 🧵👇

A new preprint 📝 with @tobiasuhauser.bsky.social @kenzakdr.bsky.social @benjwagner.bsky.social and Andrew Webb accompanying our cpm-toolbox.net python modelling library - including details about our motivations, toolbox features, framework and workflows! 👉 osf.io/preprints/ps...

Some really cool stuff here! Really glad to have been involved in the making 📝🥳 day-to-day fluctuations of confidence (across multiple domains) relate to OCD symptom reports

Journal publishers *are* bundling your papers up in "data licensing agreements" for big tech companies to use for AI model training. Our publisher, T&F, got £75m from Microsoft for that last year alone.

Our research on video game loot boxes was cited in a recent Forbes article about Labubus. The article was a systematic review exploring the links between loot boxes, problem gambling and problem video gaming. In other words, purchases with chance-based outcomes. 1/2 www.forbes.com/sites/traver...

New models (three variants of Prospect Theory), new features (more ways to manage parameters, more model components to use), and of course bug fixes. If you want to make your computational modelling reproducible and robust, check out and install the new version of *cpm*: github.com/DevComPsy/cp...

Ever have a symptom & assume the worst? That’s the Inverse Base Rate Effect—we over-focus on rare outcomes. A new #psynomPBR study by Dome @lenarddome.bsky.social & Wills finds distraction & time pressure can reduce this bias. Post by Alyssa Asmar. buff.ly/FTDQE25

I wonder how much tax money goes into research programmes likely this? In Europe for example? A shame indeed

So excited to share that the NeNa registrations are open now! Can’t wait to see everyone in Heidelberg this October. 🎓🍂

5. The right-wing enthusiasm for AI science is not about doing better science faster. It’s about eliminating one of the most effective forms of societal resistance to authoritarian control.

“Even the term 'Artificial Intelligence' … is widely misused, with conceptual unclarity coopted to advance industry agendas and undermine scholarly discussions. It is our task to demystify and to challenge 'AI' in our teaching, research & engagement with society.” openletter.earth/open-letter-...

A quote from Rumelhart/McClelland: "...real biological systems cannot be Turing machines because they have finite hardware." A sentiment somewhat related to our g-distance framework. What portion of unobserved but possible results your model rejects?

I'm very excited to share that @wellcometrust.bsky.social has awarded us a big grant on studying information gathering biases in #OCD and #Schizophrenia in patients, rodents, using modelling & clinical interventions. More details here: devcompsy.org/2025/07/15/n...

a couple of hours before my keynote, I went through an intense negotiation with the organisers (for over a hour) where we went through my slides and had to remove anything that mentions 'Palestine' 'Israel' and replace 'genocide' with 'war crimes' 1/

Save the date! The 2026 *gasp* Australasian MathPsych conference will be in Singapore -- looks to be a great one :) @ozmathpsych.bsky.social

New paper accepted at ACL Findings! TL;DR: While language models generally predict sentences describing possible events to have a higher probability than impossible (animacy-violating) ones, this is not robust for generally unlikely events and is impacted by semantic relatedness. 1/3

Thrilled to share the new paper from the lab out today in @nathumbehav.nature.com, led by the great @jetrach.bsky.social! "Mental graphs structure the storage and retrieval of visuomotor associations" www.nature.com/articles/s41...

I'm excited to announce that my lab's open textbook on Scientific Computing for Cognitive Neuroscience (v1.0) has just gone live! Our goal is to help mend the gap between the computational skills needed by cognitive neuroscience, and typical curricula that don't yet include it. 1/3

Israeli commandos boarded the ship, which was attempting to break the blockade of Gaza, in international waters off the coast of the territory, according to the move's organisers. www.ft.com/content/16a4...

Special kudos for Sam to release 1.3T of carefully organised and documented neuroimaging data that other researchers can use for future discoveries: gin.g-node.org/sam.hall-mcm...

For eight years, Builder .ai marketed its "Natasha" AI system as a fully autonomous tool that could build software "as easily as ordering pizza." In reality, engineers in Noida and Bangalore manually coded client projects while being instructed to mimic AI-generated responses.

I’m starting to think this is a systemic issue www.yusufimaadkhan.com/posts/mills-...

🚨🚨🚨PREPRINT ALERT🚨🚨🚨 Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!

Academia will form these little pockets -- people whose theorizing is outrageous & supported by methods outdated since the 90s -- but once it reaches a critical size those people just review each others papers & grants, form societies, hand out awards etc, like a self-contained parallel society.

NEW paper! 💭🖥️ “Combining Psychology with Artificial Intelligence: What could possibly go wrong?” — Brief review paper by @olivia.science & myself, highlighting traps to avoid when combining Psych with AI, and why this is so important. Check out our proposed way forward! 🌟💡 osf.io/preprints/ps...

There was a paper shared on BlueSky a few months ago with an example of a #LLM happily proving a false variation of a basic calculus theorem (was it the intermediate value theorem?). Now I can't find it. Anyone remember this? #AI

Happy to share some new theoretical work with @andyperfors.bsky.social that will appear at CogSci this year! We argue (and demonstrate through simulations) that people can determine how much to trust other agents by thinking about how those agents have acquired their knowledge. 1/3

Surprisingly, irrational generalization decreases as task demands rise—but only for ambiguous test items! The only model capturing all data trends? One with rapid, competitive attentional shifts—a simpler alternative to the previous title-holder, EXIT. The paper: link.springer.com/article/10.3...

I just noticed today that my R package, **psp**, a sophisticated MCMC sampling method to slice up a computational model's parameter space, has been downloaded more thank 11K times!!! Check it out here: cran.r-project.org/web/packages... #computationalmodelling #cognitivescience

Prior specification is one of the hardest tasks in Bayesian modeling. In our new paper, we (Florence Bockting, @stefanradev.bsky.social and me) develop a method for expert prior elicitation using generative neural networks and simulation-based learning. arxiv.org/abs/2411.15826

I just posted a new preprint and here it is in memes (sorry)

Our "eyetools" #R package is now available on #CRAN! It offers a toolkit for repairing data, analysing fixations & saccades, time on AOIs, and plotting. Designed to be simple to use, it offers an open source analysis pipeline for eye data. #rstats #eye-tracking tombeesley.github.io/eyetools/ind...

Finally our editorial for the "What makes a good theory?" special issue is out (co-edited with @irisvanrooij.bsky.social, @jcskewes.bsky.social, Sashank Varma, and Todd Wareham). It's an interdisciplinary issue and the contents are transdisciplinary. #philsci #metasci #cogsci #ai #psych 🧪
