I wrote up something that's been in my head for a while: psychometric methods alone can't tell us what cognitive tasks and their indicators measure. Correlating indicators across tasks is circular when constructs are defined by those same correlations. osf.io/preprints/ps... 🧵1/3

Thrilled to share that our new paper is now out in @cognitionjournal.bsky.social: "Who knows what?

Website below☺️

OK, it finally happened! My new article, "Gradience as a cognitive principle for evaluating numerical notations", is now out today in @pnas.org. By focusing on numerals' use for communication instead of arithmetic, we have a new tool to assess their efficiency. www.pnas.org/doi/10.1073/...

In today's modeling class I had a lot of fun trying to reconduce a bunch of different models to the update rule from rescorla wagner :-) it turns out that - at least for RL, bayesian update, kalman filters and hierarchically gaussian filters - it's "all" in the learning rate definition.

We have published the second short video of our series on hybrid collective intelligence. This time, @nikoz.bsky.social from @mpib-berlin.bsky.social presents how combining human expertise with AI insights can lead to better diagnostic accuracy in the medical domain. youtu.be/Xz8wBkDzjjQ

📢 New Paper 🚨 Hadza food-sharing is egalitarian, yet offers in giving games have never matched the equitable redistribution seen in real life. In this study, we allowed people to give *or* take. Lifelike equitable distributions only appeared when people took from peers in surplus. bit.ly/4kvLOwA

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

💡 Our new #preprint is available online! How do people adapt their decisions when priorities change? In our new study, we examine how the way people represent value shapes their ability to adjust in multi-goal environments. 🔗 OSF link: doi.org/10.31234/osf... It's a thread 🧵

Imagination in bonobos! I am thrilled to share a new paper w/ Amalia Bastos, out now in @science.org We provide the first experimental evidence that a nonhuman animal can follow along a pretend scenario & track imaginary objects. Work w/ Kanzi, the bonobo, at Ape Initiative youtu.be/NUSHcQQz2Ko

Across seven incentivized experiments and a large reanalysis, we systematically manipulated the presence and type of post-choice feedback in repeated risky decisions to test whether feedback shapes behavior through learning mechanisms or through anticipatory changes in preferences.

🚨 🚨 Publication alert🚨 🚨 Great work led by the brilliant @drelenamiu.bsky.social. Using agent-based models, we show that age-structured learning (kids explore broadly; adults refine/exploit) boosts long-term cultural payoffs vs. using the same strategies in random order. shorturl.at/rdlhv
