🚨Now out in Science Advances @science.org: #Parkinson's patients off dopamine medication (PD-) explore too much and exploit too little. Modeling shows they overvalue uncertainty, not that they choose randomly. On levodopa (PD+) they become comparable to controls www.science.org/doi/10.1126/... 🧵👇

Dopamine depletion in Parkinson’s increases directed but not random exploration

Levodopa restores the balance between exploration and exploitation in Parkinson’s disease.

New paper! Setting goals is so useful in complex settings because it can reduce the environment's complexity to only the goal-relevant features. But for humans, reframing comes at a cost. Could this explain why we're so bad at abandoning goals that are no longer worthwhile? 🧵

What predicts mental health disorders' onset and treatment success? Join our free #CCN2026 satellite meeting on the latest computational cognitive neuroscience parsing the multi-scale, dynamical systems of disorders that emerge across development, symptom expression, presentation & treatment.

Hello world! 👋 We’re Minds, Machines, and Brains (MMB) 👤🤖🧠 a new open access journal from @mitpress.bsky.social exploring the principles of intelligence and cognition across natural and artificial minds. Submissions open this Fall! 🔗 direct.mit.edu/mmb

nearly 5 years later, i've finally gotten around to cleaning up the p5.js version of this sim and putting an interactive version online for scicomm reasons. increase trails for a trippier educational experience. michaelchimento.github.io/p5_githubpag...

I'm incredibly honored to have been awarded the Glushko Dissertation Award! 🎓 Thanks to everyone who supported me along the way. If you're at #CogSci2026 in Rio 🇧🇷, I'll be presenting on Saturday at 12:25PM. I'd love to see familiar faces and meet new ones; excited for some great discussions!

The framing-the-problem.github.io/cogsci2026.h... workshop at #cogsci2026 is kicking off with an intro from @hanqizhou.bsky.social Come find us in Galvea B

Can't wait for #cogsci2026 in Rio 🇧🇷! Check out some of the exciting new work this year by the hmc-lab.com and collaborators. Sadly, @davidnagy.bsky.social won't be attending due to illness, so I'll be subbing in to help out with the framing-the-problem.github.io/cogsci2026.h... workshop.

As AI systems continue to advance, Psychology Prof. @alisongopnik.bsky.social points to the original learning model: the child. In a recent Berkeley Talks episode, she explains why children’s curiosity, exploration + learning capacity set them apart from today’s AI systems. Listen here:

Many things in the world move, and can even move behind other things. When will the cat reappear? To predict this, remembering the cat’s speed will likely help. But... how do people remember something like speed, which is defined by displacement over both (🤯) space and time? TWEEPRINT ALERT! 🚨🧵1/n

🎓Congratulations Dr. @hanqizhou.bsky.social on successfully defending her thesis with the highest distinctions (summa cum laude)! It's been an honour and a privilege working together over the past years, and you've reshaped how I understand cognition via your creative and bold ideas. Bravo! 👏🥳
