@anavili.bsky.social will kick off by talking about this preprint, in which she uses pupillometry to track how attention shifts within after images. Very innovative work! dx.doi.org/10.64898/202...

Then @veerahelmisofia.bsky.social will talk about her most recent work, dissociating contributions of arousal and optics to the correlation between pupil size and behavioral performance. dx.doi.org/10.64898/202...

And finally I will talk about a large group project in which we show that pupil-size changes alone (independently of external stimuli) trigger retinal responses. dx.doi.org/10.1111/psyp... with @olaf.dimigen.de @hakankarsilar.bsky.social @anavili.bsky.social @veerahelmisofia.bsky.social
