Cognitive Scientist (LNC2, ENS-PSL). I study how lessons, suggestions, instructions, advice and other forms of linguistic exchange shape perception, preferences and behaviors. I also keep an eye on LLMs.
I haven't given any news a while, I've been nose deep into this novel preprint with my excellent collaborators @stepalminteri.bsky.social, @urihertz.bsky.social and Bahador Bahrami: "Uncovering the semantics of teaching in
experiential learning with Large Language Models".

Very happy to be a part of this! More coming soon!
Very happy to see our paper (@nicolasyax.bsky.social and @anllohernan.bsky.social) in this list. We made the risky choice to invent new tests, validate in humans, run control experiments, etc, at the risk of not being 'fast enough', but apparently it paid off 🙂

I have the immense pleasure of of announcing that @psl-univ.bsky.social and @cognitionens.bsky.social have granted me an HDR diploma (i.e. the highest qualification in French academia). This wouldn't have been possible without @stepalminteri.bsky.social and the INCREDIBLE team at HRL/LNC2. Thank you

Oh heck yes! Wonder if I'll finally be able to drop Matlab for the remaining capricious RL models I have and go full R once and for all...

Causal Inference with the 𝚖𝚊𝚛𝚐𝚒𝚗𝚊𝚕𝚎𝚏𝚏𝚎𝚌𝚝𝚜 📦 for #Rstats. It introduces the idea of G-Computation and tries to demystify the differences between ATE, ATT, and ATU.

What a cautionary tale waiting to happen this is!!
You know the "🔹AI Overview" you get on Google Search?
I discovered today that it's repeating as fact something I made up 7 years ago as a joke.
"Kyloren syndrome" is a fictional disease I invented as part of a sting operation to prove that you can publish any nonsense in predatory journals...

This!!!!!! A plague in EEG and fMRI
In task based analysis we use multiple repetitions of a trial/block, in fact a lot across "runs". One cannot average those *before* statistical analysis because it completely misestimates variability, mishandles degrees of freedom, does not account for autocorrelation, etc.

New paper!
We previously showed that people are more likely to follow advice than observed behavior.
@anllohernan.bsky.social asks whether this behavior makes sense - are people more likely to give advice when they are knowledgeable?
The answer is yes, but it depends on advice consequences👇
