💥New paper out! Why do some people generalise threat more than others? We show that anxious people generalise more strongly, even after accounting for perceptual mistakes.
A huge (!) thanks to @ondrejzika.bsky.social @nicoschuck.bsky.social and @bernhardspitzer.bsky.social
Check out the latest from Sam HallMcMaster on the role of entorhinal cortex in factorizing representations and generalization
📘🧠💥@fabianrenz.bsky.social , @nicoschuck.bsky.social & I thought about methods to measure brain plasticity and wrote an overview of exciting new methods and developments!

Finally, we show that trait anxiety is associated with stronger generalisation and that this overgeneralization is associated with value rather than perceptual mechanisms.
7/n
Using computational modelling we show that we can dissociate perceptual and value-based generalisation. Response distributions (here for generalisation stimuli closest to the CS+) reflect predicted distributions.
6/n
We predict that trial-wise rating distributions differ for perceptual & value-based generalisation (binary vs. gradual). To generalise value, participants can draw on different functions (Gaussian-like, monotonic).
5/n
We show that outcome expectancy ratings learned for a CS+ generalise to perceptually similar stimuli - although showing different patterns.
4/n
👻Using a pretty task involving dangerous (&scary) Spaceflowers we collect data on participants’ perceptual discriminability, aversive learning and generalisation behaviour.
3/n
Generalisation of learned outcome expectancies to similar stimuli can result from confusing two stimuli (perceptual mechanism) or from the transfer of learned value (value mechanism).
We use a modelling approach to dissociate these two mechanisms.
2/n
It’s a Preprint! 👋
We show how we can dissociate perceptual from value-based mechanisms of generalisation + that stronger gen. in anxiety is associated with value rather than perception.
