"Visual representation under the surface of awareness"

Monday, April 23, 2018 at 5:00 pm

Program

Béla Julesz (1928-2003)

Salvador Dali's "Cybernetic Odalisque - Homage to Béla Julesz" (1978)  (Best seen with red-green glasses)

5:00 - 5:04pm	Introduction and Tribute to Bela Julesz by Prof. Eileen Kowler
5:04 - 5:07pm	Speaker Introduction by Prof. Thomas Papathomas
5:07 - 5:10pm	Tribute to Speaker by Dr. Barton Rubenstein
5:10 - 6:10pm	Lecture by Dr. Dov Sagi The George Zlotowski Professorial Chair​ Department of Neurobiology, Brain Research​ Weizmann Institute of Science Rehovot, Israel "Visual representation under the surface of awareness"  Bela Julesz studied “preattentive” vision, defined as vision without effort or scrutiny within the context of texture segmentation, asking whether it can process complex forms. We extend this question to “preconscious” vision, defined as vision without awareness or subjective experience. Our probe on visual awareness is Motion Induced Blindness (MIB; Bonneh, Cooperman, & Sagi, 2001), where a salient visual target perceptually disappears when superimposed onto a rotating background. We are interested in identifying the information available to the brain in the absence of stimulus awareness, in an attempt to identify a functional role for visual awareness. I’ll describe experimental results suggesting a relatively rich visual representation under the surface of awareness, with awareness having limited access to selected objects.
6:10 - 6:30pm	Q & A / Discussion
6:30 - 8:00pm	Light reception immediately following the talk will be in the Fiber Optics Materials Research Building, Lobby

Abstract: Perception, Art and Illusion
What is ‘perception’? What does it mean to perceive? What are the similarities and differences between our everyday perception of the surrounding world and our perception of artworks? How can perceptual research help us to understand art and, conversely, how can the study of art help us to understand the processes of perception? And what is an ‘illusion’? Are all our perceptions ‘illusions’? These are some of the questions that I would like to address in the 2021 Sixth Julesz Lecture. Much of what has been written about relevance of perceptual research to art has focused on low-level mechanisms such as seeing edges, contrast and colour but these aspects of perception are of little interest to artists. Instead, I would like to argue that we need to think about perception as an ability to extract meaning - what the world offers us - from sensory stimulation, and that this is just as relevant to the perception of art as it is to our everyday perception of the surrounding world.

Biosketch: Brian Rogers is Emeritus Professor of Experimental Psychology at the University of Oxford and also Professor of Psychology at the State University of St Petersburg. He started his career as an undergraduate and post-graduate student at Bristol University where he was supervised by Stuart Anstis and the late Richard Gregory. After leaving Bristol, he was appointed to a Lectureship and subsequently a Readership at St Andrews University in Scotland before moving to the University of Oxford in 1984. His main research interests are in 3-D vision, illusions and motion perception as well as the role of perception in the control of action. He has co-authored three books: “Binocular Vision and Stereopsis”, “Seeing in Depth” and “Perceiving in Depth” with the late Ian Howard and in 2017 he wrote “Perception - A Very Short Introduction” by Oxford University Press.
