Oops!

Here’s to Joey finding our preprint on biorxiv already before I saw the email it had successfully uploaded 🥂Tweeprint (/blueprint) will follow soon. With @amit-rawal.bsky.social and @mjwolff.bsky.social

Here’s a thought that might make you tilt your head in curiosity: With every movement of your eyes, head, or body, the visual input to your eyes shifts! Nevertheless, it doesn't feel like the world does suddenly tilts sideways whenever you tilt your head. How can this be? TWEEPRINT ALERT! 🚨🧵 1/n

How we move our eyes is subject to certain temporal and spatial regularities. These statistics may be different for me that they are for you. Are people sensitive to their own unique eye movement patterns? Tomorrow at #ECVP @amit-rawal.bsky.social will talk about this at 11.30 in lecture hall P1!

Welcome #VSS2025! For those attending the sunny, beaches, and science at this years Florida conference, make sure not to miss the awesome talks and posters from our lab!

Diversity of eyes

RGC=Retinal Ganglion Cells

Incredible diversity of eyes and vision across animals! These reviews really make you appreciate the evolution of the eyes and their perfect adaptation to the animal's lifestyle. Mice don't have a fovea, Hawks have two!

Variable processing shifts during perceptual acceleration: Evidence from temporal integration The perception of a stimulus can be accelerated by another that precedes it. Research to date has focused on quantifying this acceleration, and localizing it in the chain of perceptual and cognitive processes that are involved. This is challenging, because these processes may interact unexpectedly, and because traditional (univariate) analyses of brain activity and behaviour may conflate processes with the representations they act on. By using multivariate pattern analysis of EEG data from a missing element task, designed to measure the visual temporal integration of two successive stimulus displays, we were able to track the representation associated with the integrated percept. We manipulated the delay between our displays, and observed commensurate acceleration of the resultant integrated representation. Furthermore, regardless of the delay, we found that although processing was already accelerated during the earliest processing stages at around 100ms after stimulus onset, intermediate stages, at around 200ms, were even more accelerated. In contrast, later processing stages, at around 400ms, again showed less acceleration. The results thus suggest that perceptual acceleration during temporal integration is nonlinear, and that some time that is gained at one moment in the process can be lost again at another. ### Competing Interest Statement The authors have declared no competing interest.

New preprint by Michael Wolff and me, on accelerating visual perception! The perception of an image can be accelerated by another before it. But how does this happen in the brain? Michael developed a new method to quantify the temporal shift across time in EEG. 1/3

Congratulations to Karl Gegenfurtner who won the 2024 Pineapple Science Award in Psychology (kind of Chinese “Ig Nobel”) for his work on how oranges can be perceptually ripened, that was published in i-Perception!

Getting high-quality eye tracking can be hard, especially when combined with other techniques like MEG or fMRI.

I started collecting a few tips for improving data quality that you won't find in a manual. If you know more, please reach out! matthiasnau.com/eye_tracking...

Non-visual spatial strategies are effective for maintaining precise information in visual working memory Visual working memory content is commonly thought to be composed of a precise visual representation of stimulus information (e.g., color, shape). Neve…
