I gave talk about subjective and objective approaches in the study of conscious perception last week in a BAMΞ workshop @uni-bamberg.de hosted by @johanneskleiner.bsky.social
@jolienfrancken.bsky.social and
@ronyhirsch.bsky.social. You can find the recording here: www.youtube.com/watch?v=S1zB...

thank you!! it was very unexpected
thank you!! hope to run into you in sometime
(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!! 🙌🥳🪅

While our findings offer convincing evidence for unconscious priming at the single-subject level based on proper statistical procedures, our study also emphasises the importance of providing clear instructions and sufficient training to appropriately assess awareness.
When directly comparing prime and mask discrimination, we found an indirect task advantage in the same three participants for whom we showed unc. priming using the double t-test approach.
In this framework, unconscious processing occurs if there is an indirect task advantage (priming effect) over the direct task (prime discrimination), which would indicate the indirect task is capitalising on information that is otherwise not available consciously.
Because the double t-test approach is inherently wrong, using the median-split technique, we recoded the mask discrimination (indirect task) reaction times into accuracy to directly compare them with prime discrimination responses (direct task).
Even after training, some SOAs still showed chance prime discrimination (although not in all SOAs, as in Vorberg et al.). Using the double t-test approach, as in Vorberg et al. (2003), we established unconscious priming in at least one SOA for 3 participants.
Unlike in Vorberg et al., some participants could already discriminate the prime at longer SOAs even before training. In the priming task, however, we replicated Vorberg’s main pattern of results.
We tackled common issues in unc. priming research: reliance on a non-significant p-value to claim no awareness, lack of direct comparison between awareness and priming, and insufficient training for participants.
In Vorberg et al. (2003), participants were slower to respond to an arrow-shaped mask when it followed an arrow-shaped prime pointing in the opposite direction, despite participants not being aware of the prime. Or they were faster if both prime and mask were pointing in the same direction.
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.

with @svangaal.bsky.social @timostein.bsky.social
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
