(1/6) My first first-author paper is now out in @nconsc.bsky.social! Part of my PhD work with @mamassian.bsky.social at @lsp-ens.bsky.social. We looked at how confidence behaves during a perceptual learning task with no feedback. academic.oup.com/nc/article/2...

Perceptual learning without feedback is accompanied with systematic changes in confidence processing

Abstract. Perceptual learning can occur without external feedback, raising questions about what internal signals might guide this learning. Here, we test t

Had a great time presenting my first poster at #VSS2026! 👀🧠 Grateful for all the insightful discussions and feedback, and loved seeing many great talks and other posters. We introduced a new paradigm + computational model to study confidence updating during active sampling in decision-making. 💭

When ferrets 🐾 make mistakes, does the premotor cortex 🧠 know it? A new study by J. Boucher, S. Shamma and Y. Boubenec in @plosbiology.org uses functional ultrasound imaging to show that premotor cortex tracks the perceived stimulus, not the one reported by behavior. ⬇️

Premotor cortex hemodynamic responses primarily reflect perceptual rather than specific motor aspects of decision making

How do frontal brain regions guide decision-making in the context of perceptual and non-perceptual factors? This study in ferrets shows through functional ultrasound imaging that activity in the brain...

A forest, a desert, have unique acoustic signatures in frequency and time. A study from our lab (N.Miller, C.Lorenzi) shows that soundscapes recorded over different continents distinguish habitats and follow the global biodiversity decrease from tropical to polar regions. @cognitionens.bsky.social

Modulation statistics of natural soundscapesa) - PubMed

Modulation statistics of "natural soundscapes" were estimated by calculating the modulation power spectrum (MPS) of a database of acoustic samples recorded in nine pristine terrestrial habitats for four moments of the day and two contrasting periods, differing in precipitation level. In particular, …

Preprint out, from my work with @mamassian.bsky.social and Anne! We show that time perception is shaped not only by context but also by structural constraints, by extending classical Bayesian models by explicitly quantifying a structural prior impacting duration discrimination. shorturl.at/q8bE6

Modeling how contextual and structural biases shape duration perception

Human time perception is flexible and shaped by both structural constraints and contextual influences. Disentangling these sources of bias is essential for understanding the predictive mechanisms unde...

We are remarkably good at recognizing natural auditory “textures”, such as the soothing sound of a running brook or fire crackling in a chimney. But do you think you could remember the exact rain texture that opens “Riders on the Storm”?
