So fun to see this out! Thanks to friends, family, and colleagues for the support (and hi mom) perception.jhu.edu/files/PDFs/2...
screenshot of the first page of a bio of chaz for an apa early career award excerpt from the article: "Chaz was born and raised in Toronto, Canada, to parents Sherry and Jay. His younger brother Ross is an MD/PhD who worked on the front lines of New York City’s COVID-19 response and now studies and treats rare cancers. “Even though he is half the doctor that Ross is (just a PhD),” Sherry once posted on social media, “I still love Chaz just as much!”" (the quote from chaz's mom is highlighted)

this reminds me that I should tell Jeremy Goodman that he was right and I was wrong about this, I tried to work on it for a while and the common knowledge case does create a ton of complications that don't arise for K-omega

Now out in @science.org: @chazfirestone.bsky.social and I review Steven Pinker's new book "When Everyone Knows that Everyone Knows...". We learned a ton from it, but think its central thesis—that common knowledge explains coordination—faces a powerful challenge. 🧵

BDH has done a vastly better job than the NYT so far. (You wouldn't be surprised.)

Love this work by @dillonplunkett.bsky.social and @jorge-morales.bsky.social! Representational momentum beyond motion 👇

When we see something that's moving, our memories about it end up projected forward in time: We remember it further along than it was. In a new paper in 𝘗𝘴𝘺𝘤𝘩𝘰𝘭𝘰𝘨𝘪𝘤𝘢𝘭 𝘚𝘤𝘪𝘦𝘯𝘤𝘦, out today and led by @dillonplunkett.bsky.social, we demonstrate that this happens even when there is 𝙣𝙤 𝙢𝙤𝙩𝙞𝙤𝙣 𝙬𝙝𝙖𝙩𝙨𝙤𝙚𝙫𝙚𝙧.🧵

The call for commentaries on our "Core Perception" paper is now live! We would love to know what you think about this new perspective on the nature of early emerging knowledge.

Details here: www.cambridge.org/core/journal...

Proposals due Dec 29!

I mostly make fun of posts like this, obviously, but I just have learned such an incredible amount from basically everyone in this department, and the vibes are great, and the work is so so good, I’m willing to compromise my Personal Brand on their behalf

Can’t imagine there’s anyone on the fence about applying who cares what I think, but fwiw and imho: this is a *really* exciting and special department, so if you were waiting for the Noam chompers signature endorsement™️ to apply, here you go

Are humans really the only rational animals? Our NEW PAPER 🎉 out in @science.org suggests otherwise! In a large collaboration led with my joint first author @hanna-schleihauf.bsky.social, we show that “Chimpanzees rationally revise their beliefs” 🧵
Chimpanzees rationally revise their beliefs
The selective revision of beliefs in light of new evidence has been considered one of the hallmarks of human-level rationality. However, tests of this ability in other species are lacking. We examined...

we made it boys! (from the @chronicle.com)
screenshot of a 'daily briefing' from the chronicle of higher education, about zeke and elli accepting an award with chaz: Perhaps the most frustrating challenge for working parents is when they have two important places to be at the same time. But every once in a while, it all works out. That happened recently for Chaz Firestone, an associate professor of psychological and brain sciences at the Johns Hopkins University. Firestone was to accept a distinguished scientific award for an early-career contribution in the area of perception and motor performance from the American Psychological Association. The award ceremony, though, was “scheduled at peak bedtime,” as Firestone put it in a Bluesky post. The saving grace: The ceremony was on Zoom. So Firestone was able to attend, alongside his pajama-clad children, 5-year-old Zeke and 2-year-old Elliott. If the photos are any indication, the kids didn’t mind the change of routine.
