🎉🎓 Big congrats to @josefinehebisch.bsky.social who successfully defended her thesis "Through the Eye of the Beholder: Pupil-Linked Arousal in Memory Formation and Decision-Making" last week and earned her PhD "summa cum laude"! So proud of your accomplishments!

New paper from my PhD out in @elife.bsky.social! 🎉 We asked: when the state of the world is changing, how does the brain adjust how much incoming evidence is accumulated? Turns out there isn't one answer—there are (at least) two. 🧵

🎯New preprint! The resource-rational dynamics of evidence accumulation www.biorxiv.org/content/10.6... Evidence accumulation isn’t stationary. It is dynamically controlled to trade off information gain against cognitive effort. With Jiang Mao, Tobias Donner @donnerlab.bsky.social, Alan Stocker

How do catecholamines like #noradrenaline influence perceptual #DecisionMaking? @degeelab.bsky.social @donnerlab.bsky.social &co show that higher #catecholamine levels reduce individual choice history biases by dampening bias in the accumulation of sensory evidence @plosbiology.org 🧪 plos.io/4mMmNNX

Experimental design and effects on peripheral arousal markers. Top left: Design was within-subject, double-blinded, randomized, and placebo-controlled (Materials and methods). Additionally, the stimulus-response mapping was counterbalanced within participants Bottom: Schematic sequence of events during the spatial contrast discrimination task (Materials and methods). Participants reported the location of the highest contrast Gabor patch (difference in contrast is high for illustration only). Top right: Heart rate and pupil size measured as the average across task blocks (Materials and methods), separately for placebo and atomoxetine sessions. Every connecting line is a participant; large data points in the middle are the group averages.

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.
