Ever wondered why perceptual performance fluctuates over time? We found answers and new questions in our latest project, out now PLOS Biology, by analyzing over 20 million perceptual decisions in humans and mice (plos.io/46W641Q). A🧵:

New preprint alert! (biorxiv.org/content/10.110…) How does neural activity change when animals switch between engagement/disengagement? What may be the behavioral source of the changes? Are there any behavioral indicators of engagement other than the often-reported task performance

New preprint from the lab showing (another) lack of EEG expectation effects in a probabilistic cueing design 🧠⚡📈. No clear effects on ERPs or decoding performance biorxiv.org/content/10.110… Psychological Sciences Cognitive Neuroscience Hub

New paper! NMDA receptors play a dual role in human WM. We studied patients with a rare antibody to NMDA receptors, and found impairments in both associative binding and maintenance. jneurosci.org/content/early/… 1/4 🧵

A few weeks ago Eelke Spaak 🦋 @EelkeSpaak.bsky.social Michael D Nunez and Romy Frömer came to Ghent to talk about Single-trial EEG analyses. This EEG newsletter tinyurl.com/4vhd32hm is all about single-trial EEG, with video's of their excellent talks ánd a bonus video with Jelmer Borst 📽️

A systematic dissection of the analogue report methodology and comparison with "gold-standard" 2AFC. Key findings: motor noise is negligible; analogue report error is a robust measure of memory fidelity, but may underestimate perceptual precision doi.org/10.3758/s13428…

🚨New paper🚨 "Confidence in Moral Decision-Making" now published online in Collabra: Psychology (online.ucpress.edu/collabra/artic…). A shoutout to my great lab manager @OkhanMesude and collaborators Lydia Schooler, Sara Hollander, Maureen Gill Yoonseo Zoh M.J. Crockett. A thread:

Almost three years in the making, the preprint is out! We take another stab at the question: How do humans learn from reinforcement? (Spoiler alert: the answer is _not_ Reinforcement Learning). Huge thanks to the dream team: summerfieldlab @summerfieldlab.bsky.social Nathaniel Daw Kevin Miller

Happy to share a new preprint by the brilliant and indefatigable Miguel Vivar-Lazo. The first of several stories we want to tell with this rich dataset, which features joint measurements of choice, reaction time, and confidence along with ensemble recordings from LIP...

Delighted to share this preprint! How is the confidence in a decision represented in the brain? With Michael Shadlen we show that the lateral intraparietal (LIP) neurons that represent evidence accumulation also represent the probability that the decision is correct (i.e., confidence).

I’m delighted to see this paper published. Harvey did phenomenal work it was a really enjoyable collaboration with him and @ConnellLab
