The claim: anxiety distorts not just what looks threatening, but the task models people use to plan. 🧵

This tiny study provides preliminary support that world model variation is critical to explaining anxiety.

Computational models are a key part of science but discovering new ones is hard!

DataDIVER discovers concise models from data, surfacing new mechanistic ideas and generating clear predictions for future experiments

Preprint from @GoogleDeepMind Neuroscience Lab + collaborators

[Andrew Lampinen @AndrewLampinen]

We've updated the preprint of our Naturalistic Computational Cognitive Science paper — we've clarified and streamlined the arguments, and expanded examples where we see increasing naturalism already yielding new theoretical insights, from RL to perceptual neuroscience. 1/4

A standard stimulus-generalization account predicts anxious people use threat-associated keys *more*, to pre-empt new threats. We found the opposite: the actions themselves are excluded from the planning repertoire. A distinct mechanism.

However, we decided to call this under-generalization to contrast it with the stimulus generalization literature.

🔥🚨 Lab's first paper is out !! Thanks @micahgallen for reposting here.

The article is open access, showing anxiety biased how we form world/task models when when we confuse actions coincidental threat as if those actions cause threat.

Anxiety distorts not just what looks threatening but the specific task models people use to plan their actions, suggesting world model variation is critical to explaining this condition.
