💡🧠New #preprint: we tested whether reward #learning produces lasting, context-general changes in spatial #priority.
Using #EEG + #pupillometry, we found strong #reward-learning signals, but weak transfer 4 days later, suggesting limits to persistent, task-general spatial priority #plasticity.

🚨 New #Review #Preprint 🚨 Veera Ruuskanen proposes a new, concrete framework to understand how and why pupil size 👁️, neural activity 🧠, and behavior 💃 interact. doi.org/10.31234/osf... #psychology #neuroscience #pupillometry #perception
My first first-author paper, from the first half of my Master’s (almost 3 years ago, wow) is out! Happy to finally share! 👁️
Stay tuned, there's more coming soon!

Your Pupils, Your Mind 👁️🧠
Pupil size isn’t just light reflex: it tracks “pupil-linked arousal” shaped by neuromodulators (NA, ACh, 5-HT, orexin). The piece argues pupils are a 1D readout of multidimensional brain states.

Since eyes come in pairs, so do my night and day posts on pupils and irises from last week to this.

🚨 #Preprint alert 🚨 A multilab study led by Claire Vanbuckave investigated whether the strength of pupil responses to imagined brightness/ darkness reflect differences in vividness of mental imagery. We found … 👇 1/3 🧵 #psychology #aphantasia #pupillometry #mentalimagery

An imagery test you can't fake: pupils shrink when you imagine light—unless you're aphantasic. The lab tool turning mind's eye into measurable data. #Aphantasia #MentalImagery #Neuroscience #Pupillometry #VisionScience
And for anyone looking to recruit a superstar post-doc 👉 @anavili.bsky.social 🏆 has just submitted her thesis and is on the lookout, mainly in the fields of #perception, #attention, #workingmemory, #pupillometry, #eyemovements! #nvp2025 #psychology
This afternoon at #nvp2025, an entire session on cognitive #pupillometry 👁️ with talks by @anavili.bsky.social , @cstrauch.bsky.social and others. See you at 👉 12:00! #psychology
I wasn't aware of this until recently, but there is a very neat set of #OpenSesame plugins for #Tobii eye trackers! This could make life a lot easier for Tobii users! Thanks to Rosbag, Niehorster, and Nyström. osdoc.cogsci.nl/4.1/manual/e... #eyetracking #psychology #pupillometry
Standardized measures of #pupillometry are expensive & unwieldly. The authors of this #AJA study evaluated a low-cost, portable pupillometry device in indexing listening effort during a sentence recognition task. https://on.asha.org/3HNoLi0

Our group is interested in causal effects of pupil size on behavior. To investigate this, we experimentally manipulate pupil size through red (red) and blue (small) inducers. This is a cool technique, **but** it used to come with a caveat. 🧵1/3 #psychology #perception #pupillometry

The image is a graph that shows five lines (one for each emotion), punctuated with small dots for uncorrected statistical significance and bigger dots for statistical significance after multiple-comparisons correction. The x-axis is labelled "Time (seconds)" and runs from just before 0 to 30 seconds. The y-axis reads "Standardised beta coefficient" and runs from just under -0.15 to 0.3. A dotted line spans across y=0, and labels indicate that positive values mean that "Emotion predicts larger pupil" and negative values that "Emotion predicts smaller pupil". Anger (in red) shows a negative trajectory from ~5 seconds after stimulus onset, with some bits statistically different from 0. Fear (purple) is indistinguishable from 0, until it is associated with larger pupils in the last 2-3 seconds. Sadness is somewhat positively associated with pupil size, but not after multiple-comparisons correction. Happiness is associated with relative pupil dilation from ~3 seconds until the end of the stimulus. Disgust is by far the most prominent predictor of larger pupil size, with standardised coefficients about twice as high as for happiness.
NEW! Using #pupillometry during emotional stimuli, we found if/when individual stimulus ratings are associated with pupil size. In short, disgust was the strongest pupil dilator, whereas anger constricts it (a bit).

Good news for #pupillometry people! Ana Vilotijević is now on Bluesky: @anavili.bsky.social You might know her from work with @sebastiaanmathot.bsky.social that targetted intrinsically photosensitive retinal ganglion cells, e.g. doi.org/10.1093/cerc... and doi.org/10.1016/j.ne...
At #eip2025 in #Belgrade to talk about #pupillometry. Lot of respect for the Serbian researchers continuing to do research under very difficult conditions.

#Pupillometry studies in “sighted non-24-hour sleep–wake rhythm disorder " ( #N24SWD ) have demonstrated an attenuated #PIPR, suggesting that while they have retained #image forming #vision, the #circadian #light input to the #SCN ( suprachiasmatic nucleus ) is impaired.

Plot showing pupil size traces over time from stimulus onset in two conditions. The 'easy' condition shows a smaller peak pupil size while the 'hard' condition shows a larger peak pupil size.

I did a #pupillometry study! And I got a result!
Leaving labels vague for now (come see my posters at AMLaP next month for details!), but lookit! Pupils are larger when Condition is Hard than when it is Easy!

New #preprint with Martin Schaefer and Artin Arshamian, showing that pupil size 👁️ peaks during exhalation as compared to inhalation. 🫁 Question for the future: does this correlation have behavioral consequences?www.biorxiv.org/content/10.1101/2024.06.... #pupillometry #psychology
