New preprint! "Non-commitment in mental imagery is distinct from perceptual inattention, and supports hierarchical scene construction" (by Li, Hammond, & me) osf.io/preprints/psya… the title's a lot, but at least it's a decent summary

nifty write-up of cool stuff on diversity-of-thought vs. alignment, by Sonia Murthy and Jenn Hu (and I'm there too) (to be presented at #NAACL2025)
Kempner Institute at Harvard University@KempnerInst

NEW blog post: Do modern #LLMs capture the conceptual diversity of human populations? #KempnerInstitute researchers find #alignment reduces conceptual diversity of language models. Read more: bit.ly/4hNjtiI @soniakmurthy @tomerullman @_jennhu

hooray, the "Bayesian Models of Cognition" book is out, for all your Bayesian models of cognition needs :) (I contributed to 3 chapters in the book -- development, intuitive physics, theory of mind -- that can be read on the ol' website)

One of my fav recent projects is "What is Where", out in Open Mind (w/ @talboger) doi.org/10.1162/opmi_a… to get a quick sense, pick an object & suppose a friend asked ‘where is [Object]?’ it seems obvious: ‘over there’. But where do you actually point? Give it a try!

Excited to share our review on the successor representation and two important generalizations: successor features and successor models! These provide answers spanning AI, cognitive science, and neuroscience for how agents can efficiently reuse their knowledge in new situations
