Happy to share our new preprint:

Uncovering the representational geometry of durations

Is time represented along a single mental timeline? We combine behaviour + EEG to show that duration is organised in a richer, multidimensional space.

Are you sure there’s no mosquito in the room?
With @matanmazor.bsky.social, Chichi Dézier, @nfaivre.bsky.social & Louise Goupil, we study how we combine multiple sensory sources to be confident in presence and absence: While detection rely on one modality, confidence requires both channels to align!

Neural correlates of perceptual consciousness from within: a narrative review of human intracranial research Despite many years of research, the quest to identify neural correlates of perceptual consciousness (NCC) remains unresolved. One major obstacle lies in methodological limitations: most studies rely o...

Two recent #sEEG studies worth checking out if you're interested in evidence accumulation, #consciousness and #metacognition:

With @francoisstock.bsky.social, Dorian Goueytes, @meaperei.bsky.social, and many others!

Our #sEEG study is now published in Nature Communications: rdcu.be/eIkoG! 🧠
Key finding: We discovered neural evidence accumulation for visual perception that's independent of report preparation—recorded from >3000 channels across 3 experiments!

Check out our new multisensory decision study!
We tackle a decades-old Q: does faster detection of bimodal targets come from a race or co-activation between modalities? And also a vital, orthogonal Q: is it one decision process or two?
A1: co-activation
A2: two!

Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

Our paper about contention and consensus in unconscious processing research is now out in Behavioral and Brain Sciences. Check out Maor's thread! Please consider sending a comment, we are interested to continue this discussion 🤓

There’s a lot in this paper, but here are what I see as the 3 main takeaways:

Leaky evidence accumulation accounts for perceptual confidence and subjective duration Perceptual consciousness is defined as the subjective experience associated with the processing of sensory cues from the environment. Subjective experience unfolds over time and is accompanied by a se...

Through thick and thin, the ultra-resilient Ramla Msheik completed the main study of her PhD, which supports leaky evidence accumulation as a computational mechanism underlying perceptual confidence and subjective duration. Check it out!

Hey Bluesky! I’m excited to share my new preprint with @matanmazor.bsky.social and @ruvidar.bsky.social, where we show that surface-level questionnaire filling behaviours drive correlations between mental health and metacognition (confidence ratings). osf.io/preprints/ps... [1/14]

Ever wondered how basketball players know when their throws are in/out?
L. Brun & @perrineporte.bsky.social asked players to rate confidence in their throws under variable visual feedback.
Turns out vision helps adjust confidence in successful, but not failed throws:
