Have you thought of using unchained pupillometry to infer effort/arousal with _uncontrolled_ visual stimulation? Sounds crazy?
@yuqingc.bsky.social shows that convolutional modeling of pupil responses with gaze-contingent luminance changes finally allows just that!

Years went into the large-scale study that honed the cognitive load algorithm for HP Omnicept, measuring pupillometry, saccade, gaze direction, and heart-rate variability. 738 participants, 4 continents, ages 19-61, tasks varying in cognitive load. Now published!

An exciting MEG+pupillometry study by @quiringehmacher.bsky.social demonstrating coordination between mechanisms mediating perception and learning. Sensory cortex tracks prediction error continuously in a graded manner, while the brainstem only responds once crossing a threshold. Excellent summary👇
New preprint w/ @akalt.bsky.social, Juliane Schubert, Nathan Weisz, & @clarepress.bsky.social 🎉
Predictive-brain accounts treat "prediction error" as one signal. We find it's two jobs, in two dissociable systems. And one of them you can watch in the pupil, as people listen to a story. 🧵 (1/9)
