New ESM study out in J Pers! 👀 We show that disorganized schizotypy specifically predicts both psychotic- and stress-reactivity in response to social, economic, and health-related stressors - thanks a lot Levente Rónai, Flóra Hann, and Szabolcs Kéri onlinelibrary.wiley.com/doi/full/10....

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...
Discovering cognitive strategies with tiny recurrent neural networks - Nature
Modelling biological decision-making with tiny recurrent neural networks enables more accurate predictions of animal choices than classical cognitive models and offers insights into the underlying cog...

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes.
This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

AI, peer review and the human activity of science
When researchers cede their scientific judgement to machines, we lose something important.

What a great pleasure to be back in Leuven and hear about amazing research at the #saa2025 ! If you are interested in Pavlovian biases vs. regulating mood with fun activities and rumination under stress, please come by our poster this afternoon - w/ Hanneke den Ouden and @leventeronai.bsky.social

What is reflected in the cross-sectional correlation? How does it relate to associations at the level of stable individual differences vs. correlations within individuals over time? It really depends! And it's hard to know without intensive longitudinal data.

Very happy that this preprint (I'm 2nd author & taking over for the bluesky-less Vanessa Scholz) is finally out!
In a large online sample, we investigated how Pavlovian/motivational biases are associated with psychiatric symptom dimensions (as first defined by Claire Gillan)..

Quite a few studies show attractive integration between perception and imagery/VWM such that e.g. imagining a left-tilted grating makes a perceived grating seem more left-tilted. Does anybody know of any studies showing repulsion? I.e. making the perceived grating seem more right-tilted?

Fascinating work on controllability estimation in social contexts
🚀 Excited to share the first preprint from my PhD!
How do people know how much control they have in social contexts, and what are the neural mechanisms?
