We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.”
Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior.

Our new paper "Noisy memory generates value in changing environments" just got published in Adaptive Behavior! doi.org/10.1177/1059...
tldr: we find that stochastic encoding of outcomes can perform better than perfect encoding (woot?), esp. if you have asymmetric encoding (for reward vs no reward)

The idea that self-censoring is a new form of oppression forced on white men rather than a normal part of having a prefrontal cortex and existing in society is some of the biggest bullshit in the centrist/right wing coalition gender grift

Cool heated exchange. Looks like social media sometimes shows the true, dark side of people (if you missed it you missed it I guess). Otherwise the exchange is interesting, and it’s always cool to see disciplines engaging.
Hmmm. Why is this ecological, if it’s about how brains represent things?
We are excited to announce our new Simons Collaboration on Ecological Neuroscience (SCENE)! This program will unite experts in experimental and computational #neuroscience approaches to investigate how the brain represents sensorimotor interactions. www.simonsfoundation.org/2025/04/24/s... #science

And it looks like Canada will keep being Canada, the good and bad, but more importantly, we will not live in the dark timeline.

It's really hard to overstate how hugely favored conservatives were up until two months ago.
Here's the graph of Canadian polling between March 2023 and March 2025. (Reminder: blue is conservative.)
Those are months and months of 20+ point leads for Tories.

The search for neural mechanisms of behaviour often relies on a synchronic, driving view of causation, where neural activity drives more neural activity, which eventually drives behaviour. The real c...

Every time I see science in the US slowly (and rapidly) declining, I try to think how in Mexico we have a president that is a woman, a physicist, a former PI in sustainable energies and development. It helps.

A) use sunlight to drive photosynthesis in plants, let plants die, wait ~100 million years, dig up fossilized plants, burn plants, use heat to boil water, use steam to drive a rotating turbine, use generator to make electrons

One of the funnest things about going into a slightly different research direction is that at each new paper read, you come up with N questions and realize K papers afterwards they’ve all been addressed, then you repeat this branching combinatorial process until you die
