Proud of UMich grad student Rosa Muñoz for being awarded an @leakeyfoundation.org grant for her dissertation research on "The evolution and psychology of possession in macaques." Congrats Rosa, and all the new grantees!

We have a new paper out in @cp-iscience.bsky.social reporting that more socially integrated female chimpanzees have lower offspring mortality 🧪 #evosky #primates #primatology #anthropology www.sciencedirect.com/science/arti...

Check out the whole special issue of Philosophical Transactions B @royalsocietypublishing.org on ‘Selection shapes diverse animal minds’ chock-full of intriguing articles, and thanks to @cornishjackdaws.bsky.social‬ & @ellileadbeater.bsky.social‬ for organizing it!

We also applied a 'scaling ToM' approach from developmental science and found that - surprisingly - gaze following seemed to be the most 'difficult' task for monkeys to pass, and knowledge attribution the easiest (thanks to Henry Wellman for the suggestion!)

We found that rhesus and Barbary macaques are similarly successful at several metrics of social cognition, including gaze following, goal attribution & knowledge attribution, but rhesus are much bolder. This is despite major differences in their social behavior.

Cooperative and competitive social styles can yield similar theory of mind!
🐵🧠
Take a look at our paper on rhesus and Barbary macaques

New review paper on primate facial expression! 🙈🙊🙉 with @jamiewhitehouse.bsky.social @jmicheletta.bsky.social and Olivia O’Callaghan @ntupsychology.bsky.social

Check out our new paper on #drinking #tools in wild #chimpanzees! We looked at the contexts where the Kanyawara chimpanzees use tools to drink in a project started by Charlie MacKenzie as an undergraduate with senior author @zeppypearl.bsky.social, along with @kris-sabbi.bsky.social & many others!

New paper hot off the press! 🚨

Non adjacent dependency processing (or lack thereof) in bonobos.

A special one, as Kanzi, who participated in the study, passed away a few weeks ago 😢

🦍🖥️New paper on great apes in virtual environments: Chimpanzee Turning Behavior During Spatial Navigation in Virtual Environments (animalbehaviorandcognition.org/article.php?id=1390). Led by Sarah Koopman, we went back to basics and asked a simple question about object permanence and optical flow.

Are humans the only species that communicates when a collaborator is missing information?

In @pnas.org, Luke Townrow and I show that our closest relatives, bonobos, can track when a partner is knowledgeable or ignorant, and tailor communication accordingly

Xmas came early! 🎄
Very happy to share this review on combinatoriality in chimps and the evolution of language 🐵
Part of a great special issue, in a French, OA journal, that promotes multilingual science! French version to come in Jan!

Hot off the press! Is there a pre-linguistic basis for event role attribution? In our new paper out in PLoS Biology, we take a comparative eye tracking approach to explore temporal gaze distribution to agents and patients in dyadic interactions tinyurl.com/mryk7kmb
