I think this paper is a good read from a neuroscience perspective on how repetition and goal-directed reward learning are intertwined, resulting in short-cuts that correspond to decision biases as a function of task complexity. www.cell.com/trends/neuro...

Out now in Translational Psychiatry! www.nature.com/articles/s41...

Very happy that this is out www.nature.com/articles/s44.... Together with @stefankiebel.bsky.social we show that decision biases in context-dependent decision making, previously attributed to different forms of value normalization, are very well explained by habit-like action repetition.

My paper is out! Computational modeling of error patterns during reward-based learning show evidence that habit learning (value free!) supplements working memory in 7 human data sets. rdcu.be/eQjLN

A new preprint 📝 with @tobiasuhauser.bsky.social @kenzakdr.bsky.social @benjwagner.bsky.social and Andrew Webb accompanying our cpm-toolbox.net python modelling library - including details about our motivations, toolbox features, framework and workflows! 👉 osf.io/preprints/ps...

New models (three variants of Prospect Theory), new features (more ways to manage parameters, more model components to use), and of course bug fixes. If you want to make your computational modelling reproducible and robust, check out and install the new version of *cpm*: github.com/DevComPsy/cp...

Using a sequential decision making task and cognitive modelling, this study shows that human decisions are best explained by a combination of repetition bias and goal directed reward-based behavior. @benjwagner.bsky.social www.nature.com/articles/s44...

In our new preprint @saschafrolich.bsky.social , @MichaelSmolka & @StefanKiebel on how "habits interact with goal-directed behavior under time pressure", we found that habitual behavior varies as a function of context and repetition 🔄 www.biorxiv.org/content/10.1...

1/4 🧠 In our latest work jneurosci.org/content/43/4... @peterslab.bsky.social we show that chronic deep brain stimulation (DBS) of the anterior limb of the internal capsule/NAcc region impacts the reliability of intertemporal preferences in patients with treatment-resistant OCD.
