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 🫶

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!

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!

iBBA @ibbamsterdam.bsky.social · Jun 12

We just wrapped up an amazing workshop: "Vision as Prediction: Learning, Action & Biases", organized by Dr. Nicolás Sánchez-Fuenzalida & funded by iBBA.

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.

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

To survive, organisms constantly make decisions to avoid danger and maximize rewards in information-rich environments. As a result, decisions about...

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).

Nicolás Sánchez-Fuenzalida @n41c0.bsky.social · May 22

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

Nicolás Sánchez-Fuenzalida @n41c0.bsky.social · May 22

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.

Nicolás Sánchez-Fuenzalida @n41c0.bsky.social · May 22

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.

⚠️ 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)
