When you meet someone new, what kind of questions do you ask? It’s tempting to think that *really* getting to know people is just a matter of asking the right questions. Excited to share the next chapter in ongoing work on what makes a *deep question* with amazing collaborators...

1/ New preprint! Reasoning models often require hundreds of task examples and thousands of rollouts to improve on a task. How can they learn more from much less? Introducing CORE: contrastive self-reflection for rapid, sample-efficient, and interpretable self-improvement 🧵

New paper in press at Psychology of Aesthetics, Creativity, and the Arts w/ @aaronhertzmann.com interrogating the information bottlenecks that make the drawing of objects & scenes from observation so difficult. This was a really fun paper to write together--we hope it'll be a fun read, too!

If asked to draw a person's portrait, many people would say “I cannot draw.” Why is observational drawing so hard? In a new paper, @judithfan.bsky.social and I answer: it's the limitations of human vision. Learning to draw is learning skills to overcome them. aaronhertzmann.com/2026/03/23/d... 1/

This collaboration with @parastooabtahi.bsky.social @rdhawkins.bsky.social & colleagues has been such a treat! Super excited about this line of work on how people use both words and gestures to coordinate on shared understanding of multi-step assembly tasks—check it out at #CHI2026!

If you saw @judithfan.bsky.social present our poster at #CogSci2025, the full paper will appear at #CHI2026: “Gesturing Toward Abstraction: Multimodal Convention Formation in Collaborative Physical Tasks”

Screenshot of the paper. Teaser figure: five-panel teaser showing a shift from block-by-block to abstract tower descriptions. Panel 1 shows the first L-shaped tower made from three LEGO blocks (blue base, two red blocks stacked). A speech bubble says Put a blue block on the front side of the grid, with a hand precisely placing an imaginary block on a two-by-two grid. Panel 2 shows a speech bubble saying a red block on top of the blue, on the left side, with a hand holding an imaginary block vertically above the previous position. Panel 3 shows a speech bubble saying then another red block on top of that, with the right hand stacking another imaginary block. Panel 4 shows a speech bubble saying like an L shape. Two hands depict an L-shape gesture representing tower shape without position or orientation. The final panel shows the same tower in a different position and orientation, with a speech bubble reading Put a backward L-shape tower on the back of the grid and a hand indicating the back row of the grid.

CAIC has been hard at work creating an interdisciplinary hub for pursuing big questions in cognitive science. This spring we are excited to officially launch the Cognition, Agency, Intelligence Conference featuring talks by an amazing lineup of interdisciplinary researchers. See you on April 2-3! 🥳
