Ana Vilotijević @anavili.bsky.social · 08/05/2026⚡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 0217
Ana Vilotijević @anavili.bsky.social · 17/04/2026🚨New preprint! We show that pupil constriction doesn’t just regulate light input, it actually **generates** activity in the human retina and visual cortex, even without changes in visual stimulation! ⚡ Check it out 👁️ doi.org/10.64898/202...doi.org 060

We show predictions reshape the geometric layout of the neural representations by compressing the representational spread and stabilize the neural code by reducing the neural variance during memory encoding. 1199

Reposted by Ana VilotijevićSebastiaan Mathôt @cogsci.nl · 18/06/2025Namely: maybe these inducers also affect arousal and through that route behavior. Joshua Snell and @anavili.bsky.social rigorously tested this and found that the technique is solid: red and blue inducers affect pupil size, but do not appear to affect behavior by modulating arousal. 🧵2/3 131
Ana Vilotijević @anavili.bsky.social · 18/06/2025Blue light strongly constricts the pupil—thanks to ipRGCs—but can we use it to manipulate pupil size without messing with behaviour? In a simple 2x2 (background color x task difficulty), we (w/ Joshua, Luise @vuamsterdam.bsky.social) show that background color affects pupil size, but not behaviour!biorxiv.org 010
Reposted by Ana VilotijevićJan Theeuwes @jthee.bsky.social · 26/05/2025Through experience, humans can learn to suppress locations that frequently contain distracting stimuli. Using SSVEPs and ERPs, this study shows that such learned suppression modulates early neural responses, indicating it occurs during initial visual processing. www.jneurosci.org/content/jneu...jneurosci.org 0169
