- 📰 New preprint! We show using computational modelling that transdiagnostic compulsivity is associated with greater uncertainty about learned task structure This work was led by Siri Sookud, starting during her MSc osf.io/preprints/ps...
- Reposted by Bethan BarrettI'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...
- Reposted by Bethan BarrettWe're wrapping up for the year at BRIC, and what a year it was! After a good rest, we will be ready for more wonderful research in 2026. Happy Holidays, everyone!
- Reposted by Bethan BarrettNew study out today in Nature Comms: www.nature.com/articles/s41..., in which we set out to test whether ultrasound could influence the reward-related learning computations of the nucleus accumbens, building on decades of work on dopaminergic prediction error and reinforcement learning. And it did.
- Reposted by Bethan BarrettI updated a blog which I wrote a few years ago about PhD applications. There's a mix of reflections and practical tips which should be useful for anyone thinking about applying for a PhD (at predominantly UK institutions). Please share if it could be helpful! timothysandhu.github.io/blog/phd_blog/
