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! www.biorxiv.org/content/10.6...

⚡Does attention operate *inside* an afterimage?⚡ We show that it does and that this is reliably tracked by the pupil! Once again, the pupil proves to be a pretty amazing window into the mind👁️, but what does this mean for attention? Check out our preprint! www.biorxiv.org/content/10.6... @cogsci.nl

How robust is the large-pupil advantage in visual detection? Turns out, very! Here we show with @cogsci.nl that the effect persists for different stimulus colors, eccentricities, and retinal adaptation-states ✨👀 Check it out in JEP:HPP: doi.org/10.1037/xhp0...

❤️‍🔥 Exciting new preprint ❤️‍🔥 #Pupil constriction causes, by itself and independently of visual stimulation, activity in the human #retina and #visual system. w/ @anavili.bsky.social @veerahelmisofia.bsky.social @hakankarsilar.bsky.social @olaf.dimigen.de 1/4 🧵 www.biorxiv.org/content/10.6...

🚨Pupillometrists! Reviewer2: “But what if changing pupil size unintentionally affected arousal?” 👁️ Now we give you the answer! In collaboration with Snell lab www.snelllab.eu, we show that you can safely manipulate pupil size, via ipRGC activation, without unintentionally altering arousal!

Hey bluesky 👋 really excited about this one! 👀
