osf.io The cost of thinking is similar between large reasoning models and humans Do neural network models capture the cognitive demands of human reasoning? Across four reasoning domains, we show that the length of the chain-of-thought generated by a large reasoning model predicts...

Thrilled to be one of @statnews's 2026 #STATWunderkinds for my work on language processing and reasoning in 🧠 and 🤖

Big thanks to my current/previous advisors @ev_fedorenko @roger_p_levy Marco Marelli and everyone I get to work with!

Check out CogGym, led by @LanceYing42! 258 experiments from 100 cogsci papers (!!) in one format. Main takeaway: models are getting more human-like, but way slower than improvements on math and coding

Have we built machines that think like humans? 🧠🤖

In a new preprint, we propose CogGym, which compares AI and human judgments across 258 commonsense-reasoning experiments from 100 cognitive-science papers.

New preprint! 🤖➕➗
Shared circuits predict whether LLMs generalize across formats in arithmetic reasoning

If you can solve 2+5, you can solve "two plus five" without learning math again. LLMs are more brittle (1/5)
