Two new preprints on the neural mechanisms of temporal attention! We used MEG to study how people selectively attend to items at specific time points within a sequence, when temporal predictability is controlled. With Jiating Zhu Karen Tian The Carrasco Lab David Heeger 🧵



In this new preprint (doi.org/10.31234/osf.i…), with Doby Rahnev Kai Xue Medha Shekhar, we investigated whether metacognitive noise, hypothesized to affect only Type-2 confidence ratings, also appears in Type-1 perceptual decisions influenced by expectations or rewards.

our perceptual metacognition satellite happening NOW! launching w/ hakwan lau 🇺🇦 @hakwan.bsky.social's keynote on metacognition's role in consciousness big thanks to @smfleming Lucie Charles Shao-Min (Sean) Hung and Doby Rahnev for helping launch this--150 people registered! sites.google.com/view/asscmetac…


Kicking off our metacognition satellite meeting with a talk by hakwan lau 🇺🇦 @hakwan.bsky.social! Huge thank you to Shao-Min (Sean) Hung for helping organising with @smfleming Doby Rahnev and megan peters ðŸ§


Rafiei, Medha Shekhar and Doby Rahnev develop a neural network (RTNet) that generates stochastic decisions and human-like RT distributions. RTNet reproduces features of human responses and predicts human behavior on novel images. nature.com/articles/s4156…

Exciting new work from Doby Rahnev ‘s lab!

Press release from Georgia Tech about our work: research.gatech.edu/new-neural-net…

Excited to share our piece in Trends in Cognitive Sciences on anosognosia for visual deficits which challenges the view that our conscious experiences are what we know best. We propose a model to explain these striking failures of awareness Matthias Michel Doby Rahnev cell.com/trends/cogniti…

When visual metacognition fails: widespread #anosognosia for visual deficits cell.com/trends/cogniti… by Matthias Michel Matan Mazor Doby Rahnev Isaiah Kletenik et al.; could sensory substitution help inform the metacognitive system of perceptual errors?

Excited about this new paper! Suppose you lost half a field of view, or color vision, would you notice? In a new paper in Trends in Cognitive Sciences, we show that you probably wouldn’t! You can find out more about those striking failures of visual metacognition here: authors.elsevier.com/a/1jsFQ4sIRvTB….

This was a really fun project. If you have never heard of Anton Syndrome or anosognosia but are interested in subjective perception, you're in for a treat. Great work by Matthias Michel, Yi Gao, Matan Mazor, and Isaiah Kletenik.

Out today in PNASNews with Medha Shekhar and my supervisor Doby Rahnev! Our findings challenge the Bayesian confidence hypothesis, showing humans use confidence-in-raw-evidence-space (CRES) computations when rating confidence. Here is the paper: pnas.org/doi/10.1073/pn…

Excited to share this new work with Doby Rahnev and Medha Shekhar where we tested how people compute confidence in perceptual decisions using a novel dot numerosity task. We introduced a simple yet powerful way to model multi-alternative decisions: osf.io/preprints/psya… (1/5)
