🔊 dear BSKY people, I'm looking for a chatter, blabber, cocktail party background audio generator that has hopefully been used for research before. any tip or recommendation is appreciated. reposts are also appreciated as they may bring this post closer to someone that knows 🙌
Excited to share the first publication from my PhD project: how does low-dose LSD (10 and 20 µg) affect visual perception🧠 In 30 healthy volunteers (within-subject crossover) we assessed visual perception using visual contrast surround suppression (psychophysics), and subjectively (questionnaires).
🚨 New article in #NCONSC Low-dose lysergic acid diethylamide alters subjective visual perception but not visual contrast surround suppression academic.oup.com/nc/article/d... #consciousness 🧠🧪
well on time for my bi-yearly post I'm sharing the final version of this very cool work we started with @cjungerius.bsky.social @smfleming.bsky.social @svangaal.bsky.social @fahrenfort.bsky.social in 2021, when I was young and full of hope. Now out in @natcomms.nature.com 1/11

Evidence for unconscious priming using a Bayesian single-subject approach
Abstract. Many studies have claimed the existence of unconscious priming, but a valid statistical procedure for substantiating such claims is often lacking

Have you used Bayes factor to test point-null hypotheses in Hierarchical models and wondered: 1. Bridge sampling (BS) or Savage-Dickey density ratio (SDDR)? 2. If SDDR, which density estimation method? 3. How many MCMC samples? 4. What's the cost-benefit trade-off? This may be of interest to you.
How to best estimate Bayes factors for standard hypothesis tests? We compared bridge sampling and the Savage-Dickey density ratio. The latter does a good job in most constellations typical for experiments in cognitive psychology.
my last PhD chapter is finally out 🪅🥳 (although not nicely formatted yet). it's very easy to introduce detection biases in otherwise appearance based tasks. A more digested thread coming later. w/ @cjungerius.bsky.social @smfleming.bsky.social @svangaal.bsky.social @fahrenfort.bsky.social

it is time to make my biyearly post because I put a preprint out🎉🍾😀. we (w/ @svangaal.bsky.social, Z. van den Hurk, @timostein.bsky.social & @fahrenfort.bsky.social) attempted to replicate a classic unconscious priming study by Vorberg et al. (2003) using a single-subject Bayesian approach.

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. doi.org/10.31234/osf... with @svangaal.bsky.social @timostein.bsky.social

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!
We just wrapped up an amazing workshop: "Vision as Prediction: Learning, Action & Biases", organized by Dr. Nicolás Sánchez-Fuenzalida & funded by iBBA.
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*! doi.org/10.7554/eLif....
🎉 Our paper "Criterion placement threatens the construct validity of neural measures of consciousness" is now out in eLife! 🎉 TL;DR: Both simulations and empirical data show that you should not post-hoc sort neural data based on subjective measures of consciousness. elifesciences.org/reviewed-pre...
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.
Using explicit measures of subjective experience & Bayesian ordinal modeling, this study shows that confidence reports in perceptual decisions are influenced by nonperceptual biases. @n41c0.bsky.social @fahrenfort.bsky.social @smfleming.bsky.social @juliaha.bsky.social www.nature.com/articles/s44...
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.
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
(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 📻. osf.io/preprints/ps...
