A Bayesian model incorporating representational splitting explains better memory performance in blocked compared to interleaved learning contexts. @ptoncompmemlab nature.com/articles/s4427…
Excited to share this! @TheCalipariLab we show that dopamine release in the NAc is not a reward prediction error signal, rather, dopamine signals perceived saliency. We provide a new computational model to explain our data and previous work (A THREAD 👇): cell.com/current-biolog…
Excited to share new work in @TrendsCognSci on Simplifying Social Learning: authors.elsevier.com/a/1iZ4S4sIRvTA… We highlight how social expertise lets us simplify complex reinforcement learning, offering a prototype for how people can turn hard learning problems into easier ones.

Goal commitment is supported by vmPFC through selective attention
Nature Human Behaviour - Using a combination of fMRI and lesion patient studies, Holton et al. show that human vmPFC causes goal perseveration during incremental goal pursuit.
Excited to share a review with @yael_niv! We offer that schemas are learned via RL and complementary mechanisms: dimensionality reduction, task decomposition, and latent cause inference, and that the mPFC is mediating dimensionality reduction in schemas/RL osf.io/preprints/psya…

Reward Reinforcement Creates Enduring Facilitation of Goal-directed Behavior direct.mit.edu/jocn/article-a…
🚨Out in Nature Human Behaviour🚨 Effort is costly--how can we learn to value doing effortful things? Reward effort, not outcomes/performance! Our registered report (w/ @hauselin @j_a_westbrook) shows people can learn to prefer doing effortful tasks doi.org/10.1038/s41562… /1
Two updates! 1) We have a website now! You can find us at accb-lab.com ! 💻🥳 2) We have a new preprint up with @NassarLab where we review research on learning and decision-making within a computation-centered framework. Check it out at psyarxiv.com/qndba . 🤓🧁
Excited to share this new preprint: ‘Cognitive offloading is value-based decision making: Modelling cognitive effort and the expected value of memory’. Any feedback/comments/suggestions would be highly appreciated! Brief summary below: psyarxiv.com/5e8mg/
📣Excited to share my first first-author paper in @TrendsCognSci!📣 We ask - what does the brain find rewarding and why? @docqhuys @michaelbrowni19 and I provide a novel computational account of pleasure processes and pathways to anhedonia.🧵👇 sciencedirect.com/science/articl…
Don’t have a sample funded F31, F32, K99/R00? Well now you don’t need to know someone who got one to see one. Now sharing funded and completed grants with score sheets. Plan on adding funded R24s, R25s, and R01s soon (after co-PI and collaborators approve) mcablab.science/grants/
