It's been great to be a part of such a large scale collaborative project. A big thanks to Basel Zoo for letting us work with their birds! @cog_comp_Neuch @ZooBasel

We still really need responses from pregnant women, regardless of whether you own a pet! Please take ten minutes to fill out this survey on maternal wellbeing.

There's also a French version:

We're looking for equine stakeholders (horse owners, breeders, stable managers, vets etc) to fill in this short survey, to help us assess feasibility of a possible horse welfare tool. Please share!

A student of mine is studying maternal wellbeing in people with and without pets. We're recruiting women who are either pregnant or up to nine months postpartum. Please share! https://t.co/CB9EDaKpIn

Our work on ape event cognition and the evolution of language is featured in The Conversation

Are humans the only species capable of tracking agent/patient roles? @V_DubleU &co show that #GreatApes, like human adults (but unlike infants), differentiate agents from patients, suggesting that #EventRole apprehension predates #language #PLOSBiology https://t.co/msCVK0DQ5i

📰🐒According to a study by @V_DubleU and team @UniNeuchatel, when observing someone interact with something, humans and apes both alternate attention between the two subjects. Learn more in the article of @PLOSBiology, in DE, FR and EN on our website. https://t.co/Ln3fwgazI1

It took five years of hard work and interdisciplinary collaboration to get this study out. Thanks to all collaborators, contributors, funding bodies and especially the @ZooBasel staff and apes, for making this study possible.

We conclude that, having found similar gaze patterns in humans and nonhuman apes to scenes that elicit causal inference in humans, event role attribution appears to be a cognitive precursor to language that we share with a common primate ancestor.

We only found evidence for a strong agent bias in scenes depicting food. This contrast to previous findings is likely a result of using dynamic rather than static stimuli, where gaze tracks the action unfolding over time.

Infants did not mirror adults in their ability to track event roles, suggesting this is an ability which needs time and experience to emerge.

We found that like human adults, apes showed attentional switching between agents and patients, although also attended more to background information.

Building on cross-linguistic evidence for an agent-bias when viewing static event scenes and describing events, we examined the gaze of human adults, 6 month old infants, chimpanzees, gorillas and orangutans to real-world dynamic event scenes.

Being able to distinguish between agents and patients in causal interactions is a key component of language, which appears to be grounded in a cognitive bias for causal attribution.

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 https://t.co/182f3EisZs

Great to see this submitted. Happy to have been able to contribute to this excellent team effort.

Thanks to many collaborators, we got face images of lots of primates😊! If your species are not listed blue below and you have images of them to share with us, please send me DM or email! Green...need only immature images, Orange...need both adult and immature images.
