“I start every morning at 7, with a walk by the sea. It’s something you dream about — when you’re 50 meters underground — to see a blue horizon.” Eli Sharabi returned from captivity to find out his entire family, his beloved wife and two daughters, had been murdered by Hamas.

[preprint] Probability weighting arises from boundary repulsions of cognitive noise
biorxiv.org
In both risky choice and perception, people overweight small and underweight large probabilities. While prospect theory models this with a probability weighting function, and Bayesian noisy coding...

📚 In summer 2023, my book Causal Analysis was published with @mitpress. Just two years later😉 I’m very happy to share that the lecture slides are now freely available in both PDF and LaTeX (as zip files), along with the datasets and R/Python code: 👉 https://t.co/VfahR3aqVR

Looking forward to reading!
📢 New preprint! How do humans learn from arbitrary, abstract goals? We show that, when goal spaces can be compressed, costly working-memory processes give way to internalized reward functions, enabling efficient goal-dependent RL. @Anne_On_Tw @ccnlab

Excited to share our new preprint! 🚨 Does human learning have an automatic aspect? Is it possible that we learn things that are counterproductive and only lead to reduced gains? We asked participants to choose cards to win rewards. Some cards had higher chances of winning than

Think-aloud improves behavioral predicton
Can Think-Aloud be really useful in understanding human minds? Building on our previous work, we formally propose reopening this old debate, with one of the largest Think-Aloud datasets, "RiskyThought44K," and LLM analysis, showing Think-Aloud can complement to comp cogsci.

Hey @marcdemar1 @SomniumSpace Got the new VR1 and trying to test on laptop with 4090. Does anyone know how if possible to connect the display port to the gpu-linked USB c port? Adapter currently not working think it may need to be bidirectional. Any help is appreciated!

The federal government’s $1B dollar demand is designed for one purpose and one purpose only: to devastate @UCLA and its critical mission. #StandUpForUC to defend America’s greatest public university system and support this life-saving work.

The federal government’s demand of $1 billion from UCLA puts the entire University of California system at risk. Stand with us to protect UC.

Can't wait to do this in our lab soon with our new VR1 !! 🎉🌠
I went from firing up #Unity➡️ live #World in #VR in @SomniumSpace V3.0.5 in just 3 minutes ⚡️ Opened #Unity with the Somnium SDK, clicked a button to create a sample World, hit upload… and I was inside the creation 🔥🚀 This is what creative freedom feels like.
