I'm excited to announce that I had my first (co-authored) book published today! "The Rational Use of Cognitive Resources" with Falk Lieder and Tom Griffiths (@cocoscilab.bsky.social ). You can read it for free! (see thread)

🚨City announcement🚨 LA — science is coming back to the land of lights, labs, and big ideas 🌴🔬🍻 See you May 18–20, 2026 for #Pint26! 👉 pintofscience.us/team/Los%20A...

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

One initial line of defense could be to require transparency statements regarding how instruments have been vetted to combat malicious users, based on best practices (like a STAR editor check). In a recent workshop, we aimed to create such a compendium (see @andreaaaaa.bsky.social for access)!

Why do some things stick in memory while others fade? Next Tue, Dec 9, Alan Castel (UCLA) will be presenting in @motcogmeet.bsky.social online talk series on “Memory Selectivity in Younger and Older Adults: A Value-Directed Remembering Approach.” 1/ Join us! (link below)

There's hope! This is an adversarial game, researchers will need to continuously innovate to stay ahead @kiante.bsky.social @andreaaaaa.bsky.social & @jbogard.bsky.social ran an excellent workshop at #SJDM2025 to help folks get started Materials here: kiante-fernandez.github.io/sjdm-data-va...

New paper in @cognitionjournal.bsky.social, where we show how attention impacts political choices. With an eye-tracking study, we find that people's votes aren't set in stone - they take longer to vote on divisive issues and can be swayed by gaze manipulations. authors.elsevier.com/sd/article/S...

Thanks again to the Society for Judgment and Decision Making for helping continue the discussion on creating a system for data validation in the age of accessible bots in online research. Looking forward to continuing the conversation with the community! @sjdm-tweets.bsky.social

How can we identify or block #AI #survey respondents? @andreaaaaa.bsky.social, Kianté Fernandez, @jbogard.bsky.social, and Craig Fox demoed examples, facilitated discussion, and tested our live suggestions. See their Modern Threats to Online Surveys: kiante-fernandez.github.io/sjdm-data-va...

📢 Thrilled to share our paper is out now in @natcomms.nature.com Shared computations underlie how we acquire actions that are mutually beneficial, instrumentally harmful (benefits self at the expense of others), altruistic (benefit others at the expense of self), or mutually costly 🧵 rdcu.be/eL8mZ

Excited to share our new paper out in PNAS: “Neural predictors of hidden, persistent psychological states at work.” Full paper at bit.ly/47oaGRR We brought portable fNIRS into the field to predict the subjective work-related “lenses” of business leaders. Check out the thread below for more! 1/8

Awesome new preprint from @jasonleng.bsky.social! Deadlines in decision making often truncate too-slow responses. Failing to account for these omissions can (severely) bias your DDM parameter estimates. They offer a great solution to correct for this issue. doi.org/10.31234/osf...

Two flagship papers from the International Brain Laboratory, now out in ‪@Nature.com‬: 🧠 Brain-wide map of neural activity during complex behaviour: doi.org/10.1038/s41586-025-09235-0 🧠 Brain-wide representations of prior information in mouse decision-making: doi.org/10.1038/s41586-025-09226-1 +

So excited to share our new preprint! We used behavior & pupillometry to examine how reinterpreting negative emotions shapes memory for emotionally charged events. Huge thanks to my spectacular advisor, Dave, for all his help and support with my first project of grad school! Check it out 👇

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

How to make #autodiff user-friendly? What lies beyond the safety of Python-world? Why does it matter for scientific machine learning? All this, and more, in our latest preprint with @adrhill.bsky.social! Spoiler alert: it describes the most useful software I ever wrote. arxiv.org/abs/2505.05542
