Now published in Neuroscience of Consciousness academic.oup.com/nc/article/202… Special thanks to Doby Rahnev and @smfleming, whose insightful (signed) reviews substantially improved the paper.

My thesis work comparing models of metacognition is finally out :) Grateful to Doby Rahnev (as always) and my thesis committee (particularly Rani Moran) for guidance and insightful discussions

My first first-author paper with Doby Rahnev is out! In this paper, we discussed what confidence response times (cRTs) can tell us about underlying confidence computations. Link to full text⬇️ jov.arvojournals.org/article.aspx?a…

Once, we ran a study on Prolific and a participant wrote on Reddit that the study “Felt like I was losing the will to live.” I went on the Prolific Subreddit (24k members!) and asked what matters. Here is what they told me. A thread on happier participants and better studies 1/9

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.

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…

Thrilled to see this paper published in Nature Human Behaviour. It was a multi-year effort from Farshad and Medha to marry modern neural networks with traditional cognitive models. The resulting network, RTNet, mimics the critical features of human perceptual decisions.

Now out in Computational Brain & Behavior, work let by the excellent Sebastian Hellmann, suggesting that confidence in perceptual decisions depends directly on time elapsed since the beginning of the decision process: link.springer.com/content/pdf/10…

⭐️PhD in Cognitive/Computational Psychology⭐️ PhD alert! Do your PhD with me and use Reinforcement Learning to study how misinformation affects us. Deadline: October 7. Please RT! For more information: findaphd.com/phds/project/c…

We are very excited to share our new preprint about the role of emotional valence in conscious perception (manuscript currently under review). 👉osf.io/preprints/psya…

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…

In our new Nature Communications paper, we investigate the visual system's priorities for extracting meaningful information from faces and bringing it to conscious awareness. We use a new tachistoscope that enables visual presentations as short as 0.002 ms: nature.com/articles/s4146… (🧵👇)

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)
