We put out this preprint a couple months ago, but I really wanted to replicate our findings before we went to publication.

At first, what we found was very confusing!

But when we dug in, it revealed a fascinating neural strategy for how we switch between tasks

Come do a postdoc at the Wu Tsai Institute!

WTI fellows have freedom to work with anyone at the institute, and preference is given to applicants who want to work on interdisciplinary projects with multiple faculty mentors.

If you’re interested to work with me, please reach out!

Think you’re totally right that tasks often have verbal labels (eg subjs will subvocalize during task switching)

Would be surprised if they are core to the format of task reps though (eg animals have tasks)

But I also bet that these LLM have rich non-verbal reps, and cool approach for ML agents!

Cool, makes sense.

Do you think language plays a similar role in PFC? People have argued that cog maps / grid cells play a similar role

Cool project!

Do you think language training is important for this, or are these just the biggest models?

The weak stance of RL is RL as amortization, leveraging offline computation to generate a policy or value that is hard to compute just from test-time samples

At my uni there was a challenge where you had to drink one of every beverage in the cafeteria and then run to to the other cafeteria

We're a month further into the job market - how are things looking? The good news is that the market does seem to have been delayed: ~150 new listings have appeared since my last post. The bad news is that the total is still substantially lower than what it was during the covid dip.

Forget modeling every belief and goal! What if we represented people as following simple scripts instead (i.e "cross the crosswalk")?

Our new paper shows AI which models others’ minds as Python code 💻 can quickly and accurately predict human behavior!

Cool work!

What exactly was the process-level insight from this method?

Eg re: reasons to abandon think-aloud, Isn’t it possible that people don’t have introspection into their decision process, but their responses are still predictive of their subsequent choices?

I'm recruiting PhD students to join my new lab in Fall 2026! The Shared Minds Lab at @usc.edu will combine deep learning and ecological human neuroscience to better understand how we communicate our thoughts from one brain to another.
