Our results demonstrate that humans are capable of integrating multiple outcomes (two at least) during reinforcement learning. However, this integration tends to favour positive and confirmatory information, with traces at behavioural, computational and physiological (Eytracking) level.

📢 New preprint📜 out 🚨:
"Biased processing of multiple outcomes in human reinforcement learning: evidence from computational modeling and eye-tracking"

How do we integrate multiple outcomes that stem for a single decision?

And huge thanks again both RIKEN CBS-Toyota Collaboration Center (btcc.riken.jp/en/) and @eslr.bsky.social for your generous support! And thanks a lot @tatsushi-usui.bsky.social for the stunning logo design and local organisations!

Me and @watarutoyokawa.bsky.social want to thank everyone who attended, presented at, and helped organize #COSMOS2025! If you weren't able to make it, all teaching materials are already online and we'll be uploading videos of all talks soon cosmossummerschool.github.io/materials/

Using social reinforcement learning to figure out which japanese konbini (convenience store) is superior. Where are you getting your strong zero, onigiri, or egg sandwich?
Last #COSMOS2025 talk of the day by Shinsuke Suzuki sites.google.com/view/szklab/...

Mayuko Nakamaru pointed what if gossips, a said-to-be key mechanism of human indirect reciprocity, have lies. Her evo. models seem to have many rooms to be addressed by cognitive models too! #cosmos2025

I just had a lovely morning teaching memo with Lio Wong at #COSMOS2025 in Tokyo! Charley and Wataru have put together an absolutely *fantastic* summer school. Fascinating talks, delightful people… and excellent location. I feel so lucky to be here. If you ever get a chance to attend COSMOS, take it!

Afternoon session #COSMOS2025 is about trying to cooperate with lying gossips… 😵 but only in prisoner’s dilemma 😌 by Mayuko Nakamaru (sites.google.com/view/mayukon...)

Now up at #COSMOS2025: @kartikchandra.bsky.social & Lio Wong giving a tutorial on recursive social reasoning using MEMO github.com/kach/memo
Fun fact: those flowers between them and 🗻 are called "cosmos".

The first lecture of the day at #COSMOSTokyo is on various social and strategic learning scenarios and their underlying neurocomputational mechanisms, by Lusha Zhu (www.lushazhu.com)

@thecharleywu.bsky.social is giving our second tutorial explaining how we can study complex social behaviour through computational models. As always, code and demo are available in the website! cosmossummerschool.github.io/notebooks/tu...

Shifting the spotlight from dominance towards shared decision-making in collective groups @damienfarine.bsky.social #COSMOS2025

Up now at #COSMOS2025 @lucymaplin.bsky.social presenting work on social learning and cultural inheritance in wild great tits 🐦

The first lecture of #COSMOSTokyo given by @lucymaplin.bsky.social showing a variety of innovations in birds reported in the citizen science app! www.spotteron.net/apps/regiona...

Key dimensions of social learning problems. @watarutoyokawa.bsky.social giving the first tutorial of #COSMOS2025 As always, course materials are opening available on our website cosmossummerschool.github.io/materials/

COSMOS2025 kick started!! And we’ve got the generous support from #ESLR community for the ESLR travel award!! Join ESLR if you are interested in social learning, cultural evolution, collective behaviour, and beyond!!

🥁COSMOS 2025 Tokyo edition official kick-off in RIKEN🇯🇵! We had a poster session as a starter🧑‍🎓. Lots of interesting computational stuff with collective things and social matters🤓.
Organized by @thecharleywu.bsky.social and @watarutoyokawa.bsky.social
