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

The act of detecting a stimulus contaminates measures of conscious experience with decision biases - Nature Communications

A central challenge in consciousness research is determining whether people truly experience a stimulus. Here, the authors show that context biases traditional detection measures, whereas continuous r...

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.

Zurich Cognition Lab@cognition-zurich.bsky.social · last mo.

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

(a bit late but) i'm beyond happy (and in disbelief tbh) to share that i got a Marie Skłodowska-Curie Postdoc Fellowship to study hallucinations with @smfleming.bsky.social at @ucl.ac.uk!! 🙌🥳🪅 marie-sklodowska-curie-actions.ec.europa.eu/news/msca-aw...

MSCA awards €404.3 million to postdoctoral researchers

1610 outstanding postdoctoral researchers were selected for funding among 17,066 applicants.

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

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

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

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.

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!

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.
