Octavio Ocampo (1992) “Equality”. The mirror reflection of the woman's face is perceived as a man's face.
A classic painting from the Mexican artist Octavio Ocampo.

This is proof that sometimes you never know how good things can get, and even then, they can sometimes get even better. 13/10 for all (TT: matiastapia2409)
Floor heating elements that have a square shape look like diamond tiles when light grazes the surface.
In this image, the square tiles look like diamond shapes when light grazes the surface.
(The square tiles are actually floor heating elements)
Probably related to the coffer illusion by Anthony Norcia.
Wow!
Congratulations to Ian Thornton and colleagues who published their Mainz-Linez illusion in i-Perception (@pec-ipe.bsky.social):
the red dots appears to wave left and right when one looks at one of the black dots, but they actually move straight

A digital CAPTCHA verification window titled "Select all squares with PIPES" against a plain white background. The window contains a 3×3 grid of numbered squares, mixing literal hardware, smoking pipes, and programming syntax.
These captchas just keep getting harder #rstats
🤔 Confidence Control. Our sense of confidence is a powerful guide for our behavior. It shapes many of the decisions we make every day: we might search for more information when we feel uncertain, ignore irrelevant feedback when we feel very confident, or adjust how we approach learning.
You're still in time to apply to BAMB! and learn the art of modeling behavior with us! 🧠
The deadline is this Friday, March 6th.
Run! 🏃♂️💨

Schulz-Hildebrandt, H. (2026). When purple perceived only at fixation: A fixation- and distance-dependent color illusion. Perception, 0(0). doi.org/10.1177/0301...
An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.
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.
From Hinnerk Schulz-Hildebrandt:

To all those who survived February, well done, march on

Photo de la librairie avec l'indication : la librairie a été perquisitionnée illégalement le 7 janvier 2026
Je réinstalle BlueSky pour relayer cette info de la librairie Violette and co qui mérite d'être connue dans le détail car il n'y a pas que la perquisition qui est très inquiétante. RT en masse s'il vous plait 💜
I love this so much. After pushback on his recent "Medicine is the only field that reaches 6 sigma" with "my field, psychophysics is so awesome" he posted this. Hurray all Psychophysicists. LETS CELEBRATE PSYCHOPHYSICS. An island of large effects is us!

I saw a tip a while ago that works sometimes: if you click on the link on the invite email and it takes you to the login page, close the tab and try clicking again, sometimes it takes you direct without needing to log in. Still annoying they make 20 profiles for you on “central” which you can’t link
