- Reposted by Lénárd Döme📢 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
- 🚨New pre-print out! 🍂 Using daily gamified smartphone 📱 tracking, we found that reductions in both self- and decision-making confidence precede when people are likely to report experiencing symptoms of OCD. www.researchsquare.com/article/rs-7...

- 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?

- This one is finally out! 🎉 We introduce g-distance, a measure that assesses model adequacy by comparing the range of behaviours exhibited by models to that of humans. #computationalmodeling #cognitivescience psycnet.apa.org/doi/10.1037/...
- g-distance comprises of two easily interpretable dimensions: accommodation (α), the proportion of observed human behaviours that the model can produce, and excess flexibility (β), the proportion of unobserved human behaviours that the model produces.
- To determine the range of a model's behaviour, we use parameter-space partitioning (PSP), a sophisticated MCMC. This method explores the model's parameter space to discover all the distinct patterns of behaviour it can generate. It slices up model behaviour into distinct ordinal behaviours.
