‼️New preprint‼️
There does not seem to be an effect of ghrelin on risky decision-making in probability discounting. Not in behaviour, underlying computational processes, or neural activity.

Lucky for you, lazy people at #RLDM2025, two of the best posters have apparently been put side-by-side: go check @maevalhotellier.bsky.social and @constancedestais.bsky.social posters!

@magdalenasabat.bsky.social used 🔌 ephys to show that ferret auditory cortex neurons integrate sounds within fixed windows (~15–150 ms) that increase in non-primary auditory cortex, independent of information rate.

#Neuroscience
Neurons in auditory cortex integrate information within constrained temporal windows that are invariant to the stimulus context and information rate
Much remains unknown about the computations that allow animals to flexibly integrate across multiple timescales in natural sounds. One key question is whether multiscale integration is accomplished by...

🚨 Finally out! My new @annualreviews.bsky.social in Psychology paper:
www.annualreviews.org/content/jour...
We unpack why psych theories of generalization keep cycling from rigid rule-based models to flexible similarity-based ones, then culminating in Bayesian hybrids. Let's break it down 👉 🧵

Epistemic biases in human reinforcement learning: behavioral evidence, computational characterization, normative status and possible applications.

A quite self-centered review, but with a broad introduction and conclusions and very cool figures.

Few main takes will follow

New preprint! 🚨

Performance of standard reinforcement learning (RL) algorithms depends on the scale of the rewards they aim to maximize.
Inspired by human cognitive processes, we leverage a cognitive bias to develop scale-invariant RL algorithms: reward range normalization.
Curious? Have a read!👇
