The Ebbinghaus illusion may be Ebbinghaus' illusion!

<August 25, 2007>

Wundt (1898, Fig. 49) cited this image as Ebbinghaus' figure. Kitaoka (2005), however, inferred that the first scholar who produced this illusion (= Ebbinghaus size illusion, Ebbinghaus areal illusion, Titchener illusion, Titchener circle, etc.) might be in fact Lipps, since the figure is found (without reference) in a monograph by Lipps (1897, p. 222), a year before Wundt's monograph and also earlier than the textbooks by Ebbinghaus (1902) or Titchener (1901). Recently, Walter H. Ehrenstein, University of Dortmund, found that Thiéry showed this image with explicit reference to Ebbinghaus even earlier (Thiéry, 1896, pp. 84-85; Figs. 51A and 51B). Thus, it is strongly suggested that the above figure has indeed originated with Ebbinghaus as had been suggested before by Ehrenstein & Hamada (1995, p. 158), based on Wundt’s (1898) account. Below is Walter's opinion:

So I think, it is Ebbinghaus who first designed it and may have communicated his figure at a congress before 1896 (rather than publish it, although this might be still the case, at that time the scientific world was quite small and people knew the work of each other even without explicit reference).

Nature, too, has highlighted this discovery! <February 2, 2012>

"Bright illusions reduce the eye's pupil"

Bruno Laeng, Professor of University of Oslo, and his colleague showed that illusions of brightness cause constriction of the eye pupil as if the eye was exposed to more light!

Moreover, one of the illusions they have used in this research was one of my illusion works 'Asahi' (morning sunlight), as shown below. Thanks, Bruno!

Laeng, B. and Endestad, T. (2012). Bright illusions reduce the eye's pupil. Proceedings of the National Acedemy of Sciences of the United States of America (PNAS), February 7, vol. 109 no. 6 2162-2167.

http://www.pnas.org/content/109/6/2162

& ScienceShot: Brightness Is in the Eye of the Beholder

Your pupil must be constricted!

Akiyoshi's further comment

This effect is kind of visual phantom illusion or Zavagno's glare effect. Note that the glare appears to be brighter at a glance than no-glare white parts, but the glare actually appears to be darker if analytically or locally (point-to-pointwise) observed, i.e. counterphase brightness induction. Thus, pupils contract in spite of dark stimuli!

Kitaoka, A., Gyoba, J., and Sakurai, K. (2006) Chapter 13 The visual phantom illusion: a perceptual product of surface completion depending on brightness and contrast. Progress in Brain Research, 154 (Visual Perception Part 1), 247-262. PDF --- Talk in ECVP2005

Akiyoshi's further comment 2

"Evening dusk"
The illusion and title were proposed by Bruno Laeng; This image was drawn by Akiyoshi Kitaoka 2012 (January 24)

The space surrounded by 'petals' appears to be darker than the outer space, though they are the same luminance. This has been given by Bruno (Figure 1b: http://www.pnas.org/content/109/6/2162), but I have never shown such a demo. Thus, I think that the credit of this effect should be given to Bruno. Or did someone show this? If so, let me know.

1st Visual Science of Art Conference | 1-2 September 2012, Alghero, Italy

<December 21, 2011>

The 35th ECVP - European Conference on Visual Perception

2-6 September 2012, Alghero, Italy

ECVP in 2012 will be held in Alghero, Sardinia, Italy from Sunday the 2nd of September to Thursday the 6th of September 2012 at the Conference Centre, situated in front of the beach, a few minutes from the town centre. For detailed information about ECVP please visit the following website: http://www.ecvp2012.uniss.it/

This year ECVP is being organized by Baingio Pinna assisted by his group of Form & Perception Lab, as well as by the Dept. of Architecture, Design & Planning at Alghero.

Alghero lies on the northwest “Coral Coast” of Sardinia, one of the most beautiful and well-known places in Sardinia and an ancient Catalan fortress on the sea, with its great bastion walls, cobbled streets of its historic centre, ancient houses and churches in little piazzas. Alghero, with its wonderful beaches and their emerald water, is a real pearl on the Mediterranean Sea.

We are honored to have two prestigious speakers for our plenary sessions at ECVP 2012:
Sunday 2nd September 2012 at 18.00, Giacomo Rizzolatti (University of Parma) - Rank Prize Lecture.
Wednesday 5th September 2012 at 18.00, David Burr (University of Florence) - Perception Lecture.

ECVP 2012 will feature participant initiated talk sessions, which will address important topics in vision research. There will also be a number of social events, such as a beach party, a Gala Banquet with traditional Sardinian music and dances, etc.

IMPORTANT DATES:

Early registration has to be confirmed and paid before 1st July 2012

Abstract submission open: 11th January 2012
Deadline for abstracts: 1st April 2012
Proposals for Symposia: 1st April 2012

Doctoral fellowships
Deadline is 1st April 2012

Poster Awards
Deadline is 1st September 2012

In 2012, ECVP will be twinned to the VISUAL SCIENCE OF ART CONFERENCE (VSAC), which is the first edition of a worldwide academic conference aimed at studying scientific interactions between vision science and art. We very much hope that there will be many of you who would be interested in attending both meetings. For more information, please visit the website of VSAC: http://www.ecvp2012.uniss.it/index.php/eng/VSAC/

In addition, VSAC and ECVP 2012 will hold a special exhibition called “IllusoriaMente” (in English both illusorily and the illusory mind) dedicated to the memory of the late Prof. Richard Gregory and Prof. Tom Troscianko and celebrating the ingenuity and creativity of both VSAC and ECVP attenders in producing attractive scientific/artistic products ranging from visual illusions to all kinds of experimental tools/procedures to applications/implementations of theories, mechanisms and principles ruling the visual system.

The 1st VSAC - Visual Science of Art Conference

1-2 September 2012, Alghero, Italy

The Visual Science of Art Conference (VSAC - http://www.ecvp2012.uniss.it/index.php/eng/VSAC/) is the first edition of a worldwide academic conference aimed at studying scientific interactions between vision science and art. VSAC in 2012 will be held in Alghero, Sardinia, Italy from Saturday the 1st of September to Sunday the 2nd of September 2012 at the Conference Centre, situated in front of the beach, a few minutes from the town centre. In 2012 VSAC will be twinned to the European Conference on Visual Perception (ECVP 2-6 September - http://www.ecvp2012.uniss.it/).

In the last decade there has been a growing interest by scientists in studying interactions between art and vision. A strongly increasing number of publications (articles, books, special issues) and meetings (workshops, symposia) encouraged researchers, scholars and students to gather together in a unitary community that can cooperate, discuss and develop new scientific perspectives in this complex and intriguing new field.
A bridge between Vision Science and Art has already been constructed. Recent scientific discoveries contribute to the understanding of Art, and Art incorporates knowledge generated by science. The VSAC 2012 further stimulates and speeds up this construction to organize a Visual Science of Art community. For detailed information about VSAC please visit the following website: http://www.ecvp2012.uniss.it/index.php/eng/VSAC/

This year VSAC is being organized by Baingio Pinna assisted by his group of Form & Perception Lab, as well as by the Dept. of Architecture, Design & Planning at Alghero.

Alghero lies on the northwest “Coral Coast” of Sardinia, one of the most beautiful and well-known places in Sardinia and an ancient Catalan fortress on the sea, with its great bastion walls, cobbled streets of its historic centre, ancient houses and churches in little piazzas. Alghero, with its wonderful beaches and their emerald water, is a real pearl on the Mediterranean Sea.

We hope that there will be many of you who would be interested in attending the VSAC.

We are honored to have a prestigious speaker for our plenary session:
Sunday morning 2nd September 2012, Jan Koenderink (Katholieke Universiteit Leuven).
