This research shows that pupils dilate when they see an optical illusion in which a black fog-like object appears to expand.

Q01. Was the expanding hole illusion already known in the scientific community before the present study, or was it specifically developed by you for this paper?

This image was not known in the science community before our study
because it was only exhibited in my website

The image is an elaborate work of the motion illusion proposed by
Kouki Fukiwara Fujiwara, a Japanese designer, in a meeting of a color society
in 2018.

Before us, “Gothic Flying Bat” painted by Gianni Sarcone, an artist,
who uploaded it on November 26th, 2013, might be the first instance
of this type of illusion. But I did not know it until recently.

“Ink blots illusion” produced by Eiji Watanabe in 2018
I think it also precedes the expanding hole illusion.
