Pre-print 🎉 "Subjective and objective approaches in the study of conscious perception" will be a chapter in www.horizon-minds.com. We explain that subjective and objective are poorly defined constructs and provide a taxonomy.

this is happening later today, drop by the unconscious processing session at 3.50 🌡️

thank you for fixing it so quickly, and also for having vegan food. I've been attending the conference for a while and it's the first time I'm not hungry all day 🫶

the answer is yes, but limited

metacontrast masking, as in Vorberg et al. (2003). Different time courses for visual perception and action priming

Are you at @assc28.bsky.social #ASSC28? On Wednesday I will present a poster on the causal relationship between choice history biases and catecholamines (noradrenaline / dopamine). With @donnerlab.bsky.social et al.

Happy to share the first project of my PhD at #ASSC28, on how voluntary strategies modulate the reading response and how this relates to suggestibility and metacognitive efficiency.

Appreciation to my collaborators, and to @fahrenfort.bsky.social for his support and supervision on this project.

Are you at @assc28.bsky.social #ASSC28? Later, @stijnnuiten.bsky.social will present exciting cross-species results on the interaction between latent behavioral states, pupil-linked arousal, and V1 activity. Great collab w/ @psterzer.bsky.social @svangaal.bsky.social @pennartz.bsky.social et al.

I will be presenting some of my postdoc work during the very last session of the conference. would love to hear your feedback 📊📢 @assc28.bsky.social #ASSC28

a small suggestion for the catering @assc28.bsky.social, @ademertzi.bsky.social #ASSC28, it would be great if the people serving would know what vegan is or at least what the ingredients of the food are. thank you!

Starting tomorrow! Join us for lots of ECR talks about topics from across the field of working memory research!

Last week not only I defended my PhD, but I also got to organized this amazing workshop with some amazing people. Thanks again to @ibbamsterdam.bsky.social for making this meeting possible!

Finally the Version of Record of our paper "Criterion placement threatens the construct validity of neural measures of consciousness" is out in @elife.bsky.social as *fundamental* and *compelling*!

Very happy this is finally out 🎉. In this paper, we show that conf. reports are biased by a visual illusion, an asymmetrical base rate and a payoff scheme. Crucially, we show that only the visual illusion affects subj. experience, suggesting decision bias leaks onto confidence reports.

If you are in Amsterdam on June 6 and predictions are your gig you will want to check out this very cool symposium I'm hosting and presenting in. Speakers: @eelkespaak.bsky.social, @clarepress.bsky.social, Ruth van Holst, @degeelab.bsky.social. See the program below.

done with these (also) lovely people: @Chris Jungerius (fix your handle), @smfleming.bsky.social, @svangaal.bsky.social, @fahrenfort.bsky.social

(couldn't wait till Monday because I'm impatient) this lovely preprint has the last part of my phd work and now is out and about 🎉🎊. will write a thread on Monday. stay tuned 📻.

Predictions and rewards affect decision-making but not subjective experience | PNAS To survive, organisms constantly make decisions to avoid danger and maximize rewards in information-rich environments. As a result, decisions about...

Have a look at the paper in which we first employed this decision/reproduction approach for assessing changes in subjective experience.

Altogether, this suggests that raw confidence reports as well as aggregated measures of metacognition are susceptible to non-perceptual decision bias. Both when the manipulation is performance-relevant (stim. prev.) and when it is not (payoff scheme).

Further, aggregated measures of metacognition (M-ratio) were also biased by non-perceptual manipulations (as identified by the reproduction task).

The same applied when confidence was reported after first-order decisions.

While all manipulations affected first-order decisions and concurrent confidence reports, only the Muller-Lyer illusion influenced the reproduced length of the lines.

Participants discriminate long and short lines, indicate their conf. on the line being short or long (concurrently or after their first order decision), or to reproduce the length of the line. We use the Muller-Lyer illusion, a stim. prevalence manipulation and a payoff scheme to bias participants.

Very happy this is finally out 🎉. In this paper, we show that conf. reports are biased by a visual illusion, an asymmetrical base rate and a payoff scheme. Crucially, we show that only the visual illusion affects subj. experience, suggesting decision bias leaks onto confidence reports.

To celebrate the defence of my PhD, and thanks to
@ibbamsterdam.bsky.social, I will host a symposium titled "Vision as prediction: learning, action, and biases" on June 6. Program, registration and more information here: bit.ly/43reOgR

⚠️ Come see our new preprint, in which we (@degeelab.bsky.social, Jasper Zantvoord, @psterzer.bsky.social, @fahrenfort.bsky.social & @svangaal.bsky.social) show that phasic (task-evoked) and tonic (baseline) arousal distinctly shape human decision bias! (1/6)

Cutting international bachelor programs threatens psychological science » Eiko Fried Two days ago, four Dutch universities announced discontinuing their English-speaking psychology bachelor programs (1, 2). I will briefly explain (1) how this decision came to be, (2) why this is such ...

Four large Dutch universities, including Leiden University where I work, have decided to throw international psychology bachelor programs under the bus in an effort to appease the rightwing government.

Here's my blog why this is a terrible idea.

got a paper accepted today, maybe life is good after all

Cognitive Neuroscience Club: "What it's like is all there is: The value of Consciousness" Our next online seminar is on Friday 7 March 2025 at 16:00. We welcome Prof. Axel Cleeremans, Center for Research in Cognition & Neurosciences (CRCN), Université libre de Bruxelles, Belgium.

Today at 16:00 (Central European Time), Axel Cleeremans (@axc.bsky.social) will present at our Cognitive Neuroscience Seminars on his lab's work on the value of consciousness. For those who want to attend, please find the relevant information (e.g. Zoom link) below. We're excited to have you, Axel!
