At the #CCN2026, I present our on-going simulation study: we assessed whether habit and/or range adaptation can explain previously observed and replicated choice frequency effects in the Reward Pairs Task - a recent instrumental learning task developed to elicit habits.

Update: the book is now officially out! Neuroeconomics: Core Topics and Current Directions is available from Springer here: link.springer.com/book/10.1007... Huge thanks again to @thepsychologist.bsky.social, @dfareri.bsky.social, and all of the contributors.

🚨📚 New book! I’m thrilled to share that our edited volume, Neuroeconomics: Core Topics and Current Directions (Springer Nature), will be out later this year. Co-edited with @thepsychologist.bsky.social and @dfareri.bsky.social — huge thanks to all our brilliant contributors. 🧵 (1/12)

My recent comment extends Shiffrin et al.'s (2026) essay on "Illusions of understanding". While they focused on multiple ways of understanding linear regression, I extend these ideas to a complex model class in cognitive science: Evidence Accumulation Models (EAMs). (1/6)👇

Many of you have probably seen this chart, which illustrates the distribution of first authors’ affiliations at NeurIPS, one of the most prestigious international conferences in the field of machine learning. But what is the situation in cognitive neuroscience? (1/n)

I have a joke about a grant but you probably won’t get it

Chapter 📖 "Decomposing Economic Choices with Drift-Diffusion Models" with @krajbichlab.bsky.social and Xiaozhi (Taro) Yang is out in, "Neuroeconomics: Core Topics and Current Directions" edited by @dvsmith.bsky.social, @thepsychologist.bsky.social, @dfareri.bsky.social tinyurl.com/yey56tup

Decomposing Economic Choices with Drift-Diffusion Models

Many decisions arise from a dynamic process of information accumulation and comparison. Thus, to fully understand decision-making, we must decompose the choice process into its parts. Here, we review ...

With some trepidation, I'm putting this out into the world: gershmanlab.com/textbook.html It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class. My hope is that this will be a living document, continuously improved as I get feedback.

This interdisciplinary program focuses on understanding learning and decision making at all levels. Applicants with backgrounds in biology, cognitive science, computer science, economics, engineering, mathematics, neuroscience, physics, psychology or any related discipline are encouraged to apply!

📢 Preprint out! biorxiv.org/content/10.1... What gives rise to probability weighting, a cornerstone of Prospect Theory? We show it comes from the natural boundedness of probabilities + cognitive noise. Adding boundaries adds multiple distortions, across risky choice & perception.

“The political environment in Russia made it hard to do science because everything was unpredictable. […] That type of uncertainty is incompatible with science, which requires the ability to plan what type of experiments and research you will do a year into the future.”

Beautiful piece of science writing from an immigrant scientist who moved to the US to escape persecution as a dissident in Russia, only to end up in ICE detention. Gorgeous images too! 🎁🔗 #AbolishICE
