The relationship between the "Rotating snakes" illusion and age has been suspected. I examined this point in a lecture entitled "Visual Illusion" invited by a series of lectures for the citizens of Osaka held at the Osaka City Air Terminal on 21st October, 2006. Forty-seven citizens participated. The age ranged between 21 and 77. The items for answer were "Rotating snakes appear to move well" (score 3), "Rotating snakes appear to move" (score 2), "Rotating snakes appear to move slightly" (score 1), and "Rotating snakes do not appear to move at all" (score 0). As a result, only two observers reported no illusory motion. These observers were over 60 years old. A weak but significant negative correlation between illusion and age was found (p < .05). This result agrees with the survey in VSS2005, USA (May, 2005) while does not with the previous examination in the University of the Air, Japan (December 2005). I guess that the latter examined too small number of observers (n = 25). To sum up, the hypothesis (proposed by Professor Stuart Anstis) that the higher the age the weaker the Rotating snakes has been accepted while the correlation is rather weak. <October 24, 2006>

****CALL FOR ILLUSION SUBMISSIONS: THE THIRD ANNUAL BEST VISUAL ILLUSION
OF THE YEAR CONTEST**** <September 25, 2006>
Dear “Best Visual Illusion of the Year” Contestant,
*** We are happy to announce the world’s 3rd annual Best Visual Illusion of the Year Contest!!*** The deadline for illusion submissions is February 15th, 2007!
The 2007 contest will be held in Sarasota, Florida (Van Wezel Performing Arts Hall) on Saturday, May 12th, 2007, during the week of the Vision Sciences Society (VSS) conference.
The 2006 annual contest, also held In Sarasota, Florida, was a huge success, which drew numerous accolades from attendees as well as international media coverage. The First, Second and Third Prize winners were Max Dursteler (Universitätsspital Zürich, Switzerland), Peter Tse (Dartmouth College, USA), and Gideon Caplovitz & Peter Tse (Dartmouth College, USA). To see the illusions, photo galleries and other highlights from the 2006 contest, go to http://illusioncontest.neuralcorrelate.com
Visual Illusion Contestants are invited to submit novel visual or multimodal illusions (unpublished, or published no earlier than 2006) in standard image, movie or html formats. An international panel of impartial judges will rate the submissions and narrow them to the top ten. Then, at the Contest Gala in Sarasota, the top ten illusionists will present their contributions and the attendees of the event (that means you!) will vote to pick the TOP THREE WINNERS!
The renowned sculptor and artist, Guido Moretti, has created three amazing works of art to serve as trophies for the TOP THREE winners!
See the trophies.
Illusions submitted to previous editions of the contest can be re-submitted to the 2007 contest, as long as they meet the above requirements and were not among the top three winners in previous years.
Submissions will be held in strict confidence by the panel of judges and the authors/creators will retain full copyright. No illusions will be posted on the illusion contest’s website without the creators’ explicit permission. As with submitting your work to any scientific conference, participating in to the Best Illusion of the Year Contest does not preclude you from also submitting your work for publication elsewhere.
Submissions can be made to Dr. Susana Martinez-Conde (Illusion Contest Coordinator, Neural Correlate Society) via email (email@example.com) until February 15, 2007. Illusion submissions should come with a (no more than) one-page description of the illusion and its theoretical underpinnings (if known). Illusions will be rated according to:
• Significance to our understanding of the visual system • Simplicity of the description • Sheer beauty • Counterintuitive quality • Spectacularity

Submit your ideas now and take home this prestigious award!

We have talk in ECVP2006 in St Petersburg, Russia, on August 21, 2006. Abstract <August 12, 2006>
Infants see the “Rotating Snake” illusion

I am sorry I will be absent in ECVP2006.
Professor Kaoru NOGUCHI, a Gestalt psychologist and a researcher of experimental aesthetics in Japan, passed away on 25th July, 2006, at the age of seventy-one. <July 31, 2006>
His contribution to the study of visual illusion
1. Geometrical illusion, especially further development of the work of
Professor Shiro MORINAGA, his teacher
He classified Morinaga's 'paradoxical' illusions into three categories, one of which is known as the Morinaga misalignment illusion.
Noguchi, K. (1982) The theory of visual illusion: Morinaga'a paradox in positional shifts. Psychology (Tokyo: Science-sha), 29 (Special issue of visual illusion), 40-47 (in Japanese).
2. Proposal of the rule that illusion magnitude positively correlates with the degree of aesthetic feeling
Noguchi, K. and Rentschler, I. (1999) Comparison between geometrical illusion and aesthetic preference. Journal of Faculty of Engineering, Chiba University, 50, 29-33.
I love this paper.
3. His last illusion was a lightness illusion!
A new illusion was proposed in a meeting in Japan! <April 10, 2006>
produced by Midori Takashima 2006 (April 10)
produced by Akiyoshi Kitaoka 2006 (April 10)
Noguchi-Takashima effect (the sumi painting effect)
A new illusion!
The regions surrounded by light borders appear to be lighter than they are while those surrounded by dark borders appear to be darker than they are.
Noguchi, K. and Takashima, M. (2006) "Watercolor effect" and Gestalt factors. Paper published in the 39th Chikaku (Perception) Colloquium (March 23-25, 2006), Takayama-shi, Gifu-ken, Japan.
Akiyoshi's comments: It resembles but is different from the Craik-O'Brien-Cornsweet effect and the watercolor effect. Although Noguchi and Takashima did not claim this effect a new one, I felt that this is quite new, so I persuaded them to give permission to show it in my webpage as a new effect. It should also be noted that the enhancement of brightness induction or filling-in given by the wavy configuration is the invention of Professor Baingio Pinna. Dr. Midori Takashima is a young perceptionist, who was a student of Professor Kaoru Noguchi.
4. He brought up many excellent perceptionists.
