T minus 7 hours to this public event on model interpretability for which I agreed to show up at 6:30am. Attendance is free!

Reminder: we're looking for 2 postdocs and 1 PhD student to join us in Barcelona to explore the computational mechanisms of perception 👁️👂🧠. With a flexible blend of theory & experiments. Please spread the word 🙏

Over 400 academics in 30+ countries signed our open letter calling for immediate changes in AI development and deployment practices to ensure that cybersecurity incidents do not continue to occur, as future incidents will be far more damaging to our critical infrastructure.

They hounded Aaron Swartz to death for downloading papers from jstor but society is now supposed to just accept mass theft because this thing can write that TPS report *for* you. en.wikipedia.org/wiki/Aaron_S...

The rich get richer in visual processing: latest study with @ivntmc.bsky.social shows that we allocate resources preferentially to stimuli that we feel confident in estimating, which makes us better at estimating them...even if the initial confidence was misplaced. doi.org/10.1038/s415...

Do the contents of visual #WorkingMemory deteriorate more quickly when more items are being remembered? Seems a straightforward question but we had to bring together 13 studies and >120,000 trials to get definitive answers... doi.org/10.1037/rev0... @ivntmc.bsky.social

Intrinsic rewards guide visual resource allocation via reinforcement learning

📣2 postdoc and 1 phD positions on computational mechanisms of human perception in Barcelona. One postdoc position (2-y) is joint w Chris Summerfield ( @summerfieldlab.bsky.social) on visual scene perception, mixing modelling w ANN and behavioral experiments.

📣 Save the date! RLDM 2027, the Multi-disciplinary Conference on Reinforcement Learning and Decision Making, is coming to Paris, July 6-9, 2027 🎉 Stay tuned for submission deadlines and more updates on our website rldm.org 👀

Open Postdoc (80%) in our Lab @uzh-ch.bsky.social (PI: Klaus Oberauer) Topics are: Working memory, long-term memory, attention; experiments, individual differences, computational modeling. Start Dec 2026 to Feb 2027, until June 2030. Apply by Oct 15; Questions to: k.oberauer@psychologie.uzh.ch

My fourth thesis paper is out in Psychonomic Bulletin & Review! 🎉 #psynomPBR (w/ @mavadillo.bsky.social, @jthee.bsky.social, #DirkVanMoorselar and @jlupiane.bsky.social). Here, we show that learning to prioritize signals of value depends on selective attention 👇🧵 doi.org/10.3758/s134... 1/7

I made an interactive demo with different visual illusions to replace the old videos we used before. Feel free to play with it here illusions.andreychetverikov.org and to use it yourself (the code is on my Github; if I missed to include somebody in the credits - please let me know).

PREPRINT UPDATE🥳👇: 🧠learning under uncertainty & metacognitive processes are not as generalizable as previously thought! both evolve differently depending on structure & stimulus set osf.io/preprints/ps...

We derived six laws of psychophysics from a single efficient-coding equation. The laws include Weber's law; scaling laws in visual working memory (which had been noted before, but with unclear theoretical justification); Wei & Stocker's law of human perception; arthurprat.com/pdfs/Prat-Ca...

Look at us, just three peas in a pod!

🎉 TODAY’S THE DAY! 🎉 #ECVP2026 begins today in Bournemouth! 👁️🧠 We’re ready for a fantastic week of vision science, workshops, talks, symposia, posters and plenty of opportunities to connect with the ECVP community. Welcome to ECVP 2026 — let’s get started! 🚀 #VisionScience #Perception

Our lab is at @ecvp.bsky.social this week, giving one talk and presenting three posters. Come and say hi!

📢 Our paper is now out in @natcomms.nature.com! www.nature.com/articles/s41... We know that symptoms of OCD fluctuate substantially. But what are the exact conditions that precede symptom escalations? We found evidence for metacognitive processes being a key antecedent. 1/

Weird, how reality is more alarming than ostensibly "alarmist" climate scientists were not too long ago. And this is still just at the beginning of a warming trend that will continue for several decades at least (unless human beings suddenly become much smarter than ever before. I have my doubts.)

Just a few more days left to nominate your female colleagues! 🧚‍♀️ Help spread some joy and appreciation for the women who do so much for our field, not just in terms of their outstanding research, but also all the labor that they do to support the wonderful WM community that we have!

Can't wait for #cogsci2026 in Rio 🇧🇷! Check out some of the exciting new work this year by the hmc-lab.com and collaborators. Sadly, @davidnagy.bsky.social won't be attending due to illness, so I'll be subbing in to help out with the framing-the-problem.github.io/cogsci2026.h... workshop.

ATTENTION!!! The program of Working Memory Symposium (WMS) 2026 (July 14-17) is out! sites.google.com/view/wmsympo... This year, WMS will feature a single stream presentation of 52 talks (39 talks and 13 blitz) + 1 panel discussion across 4 days. Looking forward to seeing you all!!!

To adapt to a new prior, tuning curves should "move" toward more frequent stimuli ('prior attraction'). But in adaptation studies they are shown to move away from the more frequent stimuli ('adapter repulsion'). Oh also how do tuning curves move at all?? www.nature.com/articles/s41...

Lovely to see the full range of excellent commentaries on our BBS article with @matthiasmichel.bsky.social, together with our response, now out: Target article: www.cambridge.org/core/journal... Commentaries: www.cambridge.org/core/journal... Our response: www.cambridge.org/core/journal...

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

1/9 📄 New in the Journal of Neuroscience: "Faster but less precise: expectation enhances response speed while reducing sensory fidelity" Does the brain prioritise the events it expects, or the ones that surprise it? We find it does both — at different stages. 🧵 doi.org/10.1523/JNEU...

If you join this committee, your ideas will influence the educations & scientific trajectories of thousands of students. Neuromatch's interactive student body has topped 14,000, estimated 40,000 engaging with Neuromatch activities & materials. One of the most impactful things you can do in science!

Open post-doc position in the study of perceptual fluctuations Position: post-doctoral (2 years) Locations: Paris, France (Ecole Normale Supérieure / CNRS) and Lausanne, Switzerland (University of Lausanne / CHUV) Deadline: September 4th, 2026 Start Date: Fall 2026 (with some flexibility) (1/8)

There are still a few spots available for the Twelfth Model-Based Neuroscience and Cognition Summer School, which will take place from 10–14 August 2026 at the University of Amsterdam. Be quick — the remaining spots will be filled on a rolling basis, so make sure to register soon!

It was AWESOME to see lots of EXCITING WM research spearheaded by early career researchers at @vssmtg.bsky.social!!! WMS community would LOVE to see your cool research in a form of talks and blitz! Abstract deadline is May 31st! (forms.gle/MccRLJC1xXQ3...)

Abstract submission for WMS2026 (July 14th-17th) is now open! If you are an early career researcher of working memory, please let us hear about your cool work by submitting your abstract (forms.gle/MccRLJC1xXQ3...). Deadline is May 31st.

It's the due date for APCV-EPC abstracts and it's been amazing watching the exponential influx of abstract submissions today. You are all people after my own last-minute heart 💙 If you haven't submitted yet, you've got til midnight NZ time!

We have 3 PhD positions at our department (www.jobbnorge.no/nn-no/ledige...). Know a good student interested in working with me on perception / visual memory? I'd be happy to support the proposal! A catch: this person must speak a Scandinavian language as the position implies some teaching duties.

Everyone's welcome! Okay, hear me out - we all agree to attend the Asia-Pacific Conference on Vision one year...or bring back international Psychonomics and put it in Australia.

Also, I’ll be giving a workshop on the first day about early vision theory and modelling. visualneuroscience.auckland.ac.nz/epc-apcv-2026/
