The Ponizsa illusion - Kanizsa triangle produces Ponzo illusion, but oddly it inverts apparent depth: the longer line looks closer! Also has an inversion effect like we studied in Altan et al 2025 Proc Roy Soc (doi.org/10.1098/rspb...) but it's also in reverse! 🤔

5% is quite a lot if you think about it. Huge N gives you the luxury to reduce alpha by a lot and still keep very high power. E.g., alpha = 0.5% (0.005) would give you 98.8% power for the same effect (in a t-test). The best balance depends on the cost of each error type, see tinyurl.com/yut35b3u >

Working memory contents can be decoded from alpha band power. But does working memory maintenance really depend on these oscillations?
We say no, because we found that alpha power decoding only works for prioritized items, not deprioritized ones. 1/3

As a theoretical cosmologist, I'm frequently asked "what is the benefit of the work you're doing for people's lives?" Nothing I work on makes money or cures disease.
There are a few different answers one can give, at various levels of "convincing" / "actually relevant to why the work is done."

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.
