We found that all groups behave rationally favoring the options that yielded more rewards! with children sensitivity to reward disparities increasing with age

4-6yo children (Leipzig, Germany), chimps and orangutans were presented with an adaptive testing paradigm that allows for tailored comparisons of preferences for collaborative versus individual action by adjusting reward payoffs based on participants’ prior choices.

In experimental studies, a preference for collaboration emerges early in child development and is considered a cornerstone of socio-cognitive development. In our recent study in published in JEP:G we challenge this assumption: psycnet.apa.org/fulltext/202...

Happy to share a short article I wrote for @theconversation.com , where I highlight our recently published EVApeCognition Dataset (www.nature.com/articles/s41...) and discuss how it can help advance research into great ape cognition and behaviour theconversation.com/great-apes-w...

Great apes: what we know about their cognition, cooperation and curiosity after two decades of research
A database of great ape research promises to unlock deeper understanding of their cognition, intelligence and social behaviour.

I would especially like to thank my closest collaborators Sonja, Carin, Akzira, and Lizbeth. Without them, this project would not have been possible. I would also like to thank the PIs Mike, Katja, Josep, and Daniel for their support throughout the years.

We hope the EVApeCognition Dataset will be valuable to anyone interested in how our closest living relatives think and behave, inspiring researchers and teachers alike to develop future projects, ideas, and methods for studying these wonderful animals

We suggest that competitive altruism in chimps does not emerge just as a by-product of them trying to increase over previous losses. Chimps might consider how others’ affect their outcomes and engage in strategies to maximize their chances of being selected as cooperative partners.

Under specific conditions, chimps outcompete first proposers in triadic consecutive trials before the responder could choose which offer to accept. They did so by offering more than what was expected if they acted randomly or offered the smallest possible amount.

Alex Sanchez-Amaro @alex-primate.bsky.social · 12/02/2024
We explored whether chimps engaged in competitive altruism in a triadic UG where two proposers could send offers to a responder who could only accept one offer. They could make offers simultaneously or consecutively. We ran dyadic control trials where only one ape could offer.
