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.

A habit and working memory model as an alternative account of human reward-based learning
Nature Human Behaviour - In this study, Collins proposes an alternative dual-process (working memory and habit) model of reinforcement learning in humans.

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.

Cognitive computational model reveals repetition bias in a sequential decision-making task - Communications Psychology
Using a sequential decision making task and cognitive modeling, we show that human decisions are best explained by a combination of repetition bias and goal directed reward-based behavior.

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...
Context-Dependent Interaction Between Goal-Directed and Habitual Control Under Time Pressure
Habits are an important aspect of human behaviour. Habits are reflexive, inflexible, and fast, in contrast to goal-directed behaviour which is reflective, flexible, and slow. Current theories assume t...

@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.
