A key challenge for computational psychiatry is to distinguish state from trait markers and go beyond cross-sectional studies. Here we show that as paranoia waxes and wanes in patients with schizophrenia, so too do volatility priors

Biological Psychiatry@biologicalpsych.bsky.social · last wk.

Individuals with schizophrenia spectrum disorders expect greater volatility in the world, and this cognitive bias is linked to paranoia and delusion severity over time.

Sensing your body (‘Interoception’) is everywhere in theories of mental health. But when we tested how well hundreds of people sensed their heart and lungs, the link to symptoms was almost nowhere to be found. 💣 🚨New @natmentalhealth.nature.com paper 🚨🎉 asks why 🧵 www.nature.com/articles/s44...

Progress in Computational Psychiatry is is slowed down substantially because researchers (clinicians, cognitive neuroscientists, etc) lack the training in computational modelling and many studies dont follow the best practices in modelling. How can we change this? We've built the CPM toolbox:

📢 Out now in PLOS Comp Biol: **cpm** — a Python library for theory-driven modelling in computational psychiatry. No scikit-learn for mechanistic cognitive models — so we built one: RL, prospect-theory & metacognition, hierarchical Bayes, and as many more as you can code 🔗 doi.org/10.1371/jour...

I've long suspected this based on our own data - most variation in unselected samples is driven by low symptom scores, and it seems that most covariation is too. Seem important, especially re implications for the "p-factor". We need to confirm correlations from unselected samples in clinical ones

Excited to share a paper recently accepted at Nature Mental Health! 😄 For decades, we've assumed that covariance among psychopathology informs comorbidity. What if we’ve been wrong?

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...
