Wurtz Laboratory of Sensorimotor Research National Eye Institute, NIH, Bethesda, MD Robert H. Wurtz is a NIH Distinguished Scientist and Chief of the Section on Visuomotor Integration at the National Eye Institute. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences, and has received many awards. His work is centered on the visual and oculomotor system of the primate brain that controls the generation of rapid or saccadic eye movements, and the use of the monkey as a model of human visual perception and the control of movement. His recent work has concentrated on the inputs to the cerebral cortex that underlie visual attention and the stability of visual perception. Brain Circuits for Stable Visual Perception Saturday, May 9, 7:30 pm Royal Palm Ballroom 4-5 In the 19th century von Helmholtz detailed the need for signals in the brain that provide information about each impending eye movement. He argued that such signals could interact with the visual input from the eye to preserve stable visual perception in spite of the incessant saccadic eye movements that continually displace the image of the visual world on the retina. In the 20th century, Sperry as well as von Holst and Mittelstaedt provided experimental evidence in fish and flies for such signals for the internal monitoring of movement, signals they termed corollary discharge or efference copy, respectively. Experiments in the last decade (reviewed by Sommer and Wurtz, 2008) have established a corollary discharge pathway in the monkey brain that accompanies saccadic eye movements. This corollary activity originates in the superior colliculus and is transmitted to frontal cortex through the major thalamic nucleus related to frontal cortex, the medial dorsal nucleus. The corollary discharge has been demonstrated to contribute to the programming of saccades when visual guidance is not available. It might also provide the internal movement signal invoked by Helmholtz to produce stable visual perception. A specific neuronal mechanism for such stability was proposed by Duhamel, Colby, and Goldberg (1992) based upon their observation that neurons in monkey frontal cortex shifted the location of their maximal sensitivity with each impending saccade. Such shifting receptive fields must depend on input from a corollary discharge, and this is just the input to frontal cortex recently identified. Inactivating the corollary discharge to frontal cortex at its thalamic relay produced a reduction in the shift. This dependence of the shifting receptive fields on an identified corollary discharge provides direct experimental evidence for modulation of visual processing by a signal within the brain related to the generation of movement – an interaction proposed by Helmholtz for maintaining stable visual perception.

In the nine years since receiving his PhD from Harvard, Frank has established himself as one of the most creative, productive young vision scientists in our field. His research artfully blends psychophysics and brain imaging to address important questions about the neural bases of awareness and object recognition. He has published highly influential papers that have been instrumental in shaping current thinking about the neural bases of multistable perception, including binocular rivalry. Moreover, Frank has played a central role in the development and refinement of powerful analytic technique for deriving reliable population signals from fMRI data, signals that can predict perceptual states currently being experienced by an individual. Using these pattern classification techniques, Frank and his students have identified brain areas that contain patterns of neural responses sufficient to support orientation perception, motion perception and working memory. The YIA award will be presented at the Keynote Address and Awards Ceremony on Saturday, May 9, at 7:30 pm in the Royal Palm Ballroom 4-5.

Vision Sciences Society 11 7th Annual VSS Dinner and Demo Night VSS 2009 Program 7th Annual VSS Dinner and Demo Night Monday, May 11, 6:00 – 9:00 pm Dinner: 6:00 – 8:00 pm Vista Terrace and Sunset Deck Demos: 7:00 – 9:00 pm Royal Palm Ballroom 4-5 Ballroom and Acacia Meeting Rooms Please join us Monday evening for the 7th Annual VSS Demo Night, a spectacular night of imaginative demos solicited from VSS members, delectable food, and social interaction. This year’s dinner theme is Caribbean Night! The demos highlight the important role of visual displays in vision research and education. This year, Arthur Shapiro and Bart Anderson are co-curators for Demo Night, and Gideon Caplovitz is assistant curator. The Caribbean-themed buffet dinner will be held on the Sunset Terrace and Vista Deck overlooking the Naples Grande main pool. Demos will be located upstairs on the ballroom level in the Royal 4-5 Ballroom and Acacia Meeting Rooms. Immersive Virtual Reality Bryce Armstrong, Edzard Ulrichs and Matthias Pusch; WorldViz We will use a 6DOF tracked environment to immerse users in virtual environments. Our goal is to show some of the VSS members experiments to demonstrate the relevance of using VR for vision science research. Unbound Rivalry Derek Arnold, Holly Erskine, Warrick Roseboom and Tom Wallis; The University of Queensland We will demonstrate that exposure to a coherent moving stimulus can induce a dynamic competition for perceptual dominance involving illusory forms signaled by motion streaks and direction-sensitive mechanisms. LITE Vision Demonstrations Kenneth Brecher; Boston University I will present the most recent Project LITE vision demonstrations (including ones not yet posted on the web) – both computer software and new physical objects. Demo Night is free for all registered VSS attendees. Meal tickets are not required, but you must wear your VSS badge for entry to the Dinner Buffet. Guests and family members of all ages are welcome to attend the demos, but must purchase a ticket for dinner. You can register your guests at any time during the meeting at the VSS Registration Desk located in the Royal Ballroom foyer. At 6:00 pm Monday, a desk will also be set up at the entrance to the dinner in the Vista Ballroom. The Bar Cross Ellipse Illusion Guest prices Thaddeus B. Czuba, Bas Rokers, Lawrence K. Cormack and Alex C. Huk; The University of Texas at Austin Adults: $25 Youth (6-12 years old): $10 Children under 6: free Gideon Caplovitz and Peter Tse; Princeton University and Dartmouth College A quad-stable stimulus leading to drastically different percepts based on differential figure-ground segmentation, assignment and integration of motion sources. Bypassing V1: Motion through depth from monocular pattern motions We show that percepts of motion through depth are supported by stimuli that effectively bypass significant binocular processing in primary visual cortex (V1). Helmholtz/Zanforlin illusion Peter Thompson and Rob Stone; University of York Asked to make a pile of coins as high as it is wide, subjects make it up to 30% too low. Simple demo with no computer! Interactive for subject. Cheap. 12 Vision Sciences Society VSS 2009 Program Perceptual Conduits for Attentional Flow: Contour Interpolation Exerts Automatic Effects on Multiple Object Tracking Brian P. Keane, Everett Mettler, Vicky Tsoi and Phil J. Kellman; UCLA We explore multiple object tracking in which moving items do or do not form interpolated connections with one another. Our demonstrations show that the ability to track clearly depends on interpolation. Subjective disappearance of targets induced by flickering illumination Sung-Ho Kim; Rutgers University Under flickering illumination, peripherally presented target lines or dots disappear. Failure of slope constancy Zhi Li and Frank Durgin; Swarthmore College Viewed from the top, the downward slope of a hill or ramp appears shallower when standing at the edge and steeper when standing back from the edge. The surface can appear to rotate upward as the observer approaches it. Growing and Shrinking: The Body-Based Rescaling of Apparent Size Sally Linkenauger and Jessica Witt; University of Virginia We will demonstrate that apparent size is judged relative to one’s body. Using magnification and minification goggles, we will show this using a newly discovered visual illusion to disrupt the relationship between physical object size and body size. Marilyn-go-round: the moving hybrid-image Takao Sato and Kenchi Hosokawa; University of Tokyo Hybrid-images combine high and low spatial frequency components from two separate images. We remove the low spatial frequency content from hypbrid images by spinning them along a curved orbit. The demo is interactive and amusing. Motion induces overestimation (MIO) Maryam Vaziri Pashkam and Arash Afraz; Harvard University We will demonstrate the motion-induced overestimation illusion. On a rotating spoked disk,as the rotation speed increases, the perceived number of spokes increases. 7th Annual VSS Dinner and Demo Night Binocular shape, unlike binocular space, is perceived veridically Tadamasa Sawada, Yunfeng Li, Zygmunt Pizlo and Robert M. Steinman; Purdue University It is widely believed that binocular space perception is inaccurate and unreliable. We will show that this applies only to depth perception, not to the perception of complex 3D shapes. The geometry responsible for this useful accomplishment will be explained. Dynamic Object Formation: Perceptual Reality Combines the Visible and Recently Visible Tandra Ghose, Evan Palmer, Brian P. Keane and Phil J. Kellman, UCLA We demonstrate perceptual completion in dynamically occluded and illusory stimuli. We explore the conditions favoring spatiotemporal completion and demonstrate the effects of component processes leading to object formation, including illusions resulting from non-veridical updating of occluded object position. The break of the curveball, rolling rolls, and other illusions Arthur Shapiro; American University I will demonstrate new visual effects involving “rotation from shading,” differences between peripheral and foveal processing, and a variant of hybrid images. Smooth pursuit suppresses motion processing Peter Tse; Dartmouth College When smoothly pursuing a moving fixation spot, real motion in the background is suppressed. Slant stereomotion from modulation of interocular spatial frequency difference Christopher Tyler and Lora Likova; Smith-Kettlewell Eye Research Institute If gratings are presented with an interocular spatial-frequency difference (ISFD), modulating the ISFD over time generates strong percepts of slant stereomotion, even when orientation or velocity differences exclude the use of conventional binocular disparity cues.

There will be four talks covering the following topics. I will moderate it and speak last on. “Advances in structural imaging of the human retina.” Before me the speakers and topics will be: D. Darcy (Advances in retinal anatomy); P. Martin (Advances in retinal physiology); and A. Roorda (Advances in optical imaging of the human retina). The speakers are all experienced researchers and lectures use to speaking to diverse audiences. Thus the level should be appropriate for all attendees at VSS from students to experts in vision or cognition. S1 Common Mechanisms in Time and Space Perception Symposium Summary Most of the actions we carry out on a daily basis require timing on the scale of tens to hundreds of milliseconds. We must judge time to speak, to walk, to predict the interval between our actions and their effects, to determine causality and to decode information from our sensory receptors. However, the neural bases of time perception are largely unknown. Scattered confederacies of investigators have been interested in time for decades, but only in the past few years have new techniques been applied to old problems. Experimental psychology is discovering how animals perceive and encode temporal intervals, while physiology, fMRI and EEG unmask how neurons and brain regions underlie these computations in time. This symposium will capitalize on new breakthroughs, outlining the emerging picture and highlighting the remaining confusions about time in the brain. How do we encode and decode temporal information? How is information coming into different brain regions at different times synchronized? How plastic is time perception? How is it related to space perception? The experimental work of the speakers in this symposium will be shored together to understand how neural signals in different brain regions come 20 Vision Sciences Society Presentations Advances and challenges in understanding the normal retina Dennis Dacey Advances in understanding circuits serving colour vision Paul R Martin, Ulrike Grunert, Sammy CS Lee, Patricia R Jusuf Advances in optical imaging of the human retina Austin Roorda Advances in structural imaging of the human retina Donald C Hood VSS 2009 Program S3 Is number visual?

Frank (Massachusetts Institute of Technology) Presenters: David Burr (Dipartimento di Psicologia, Università Degli Studi di Firenze and Department of Psychology, University of Western Australia), Michael C. Frank (Massachusetts Institute of Technology), Steven Franconeri (Northwestern University), David Barner (University of California, San Diego), Justin Halberda (Johns Hopkins University) Symposium Summary The ability to manipulate exact numbers is a signature human achievement, supporting activities like building bridges, designing computers, and conducting economic transactions. Underlying this ability and supporting its acquisition is an evolutionarily-conserved mechanism for the manipulation of approximate quantity: the analog magnitude system. The behavioral and neural signatures of magnitude representations have been extensively characterized but how these representations interact with other aspects of cognitive and visual processing is still largely unknown. Do magnitude features attach to objects, scenes, or surfaces? Is approximate magnitude representation maintained even for sets for which exact quantity is known? Is magnitude estimation ability altered by experience? The goal of our symposium is to look for answers to these questions by asking both how number is integrated into visual processing and how visual processing in turn forms a basis for the acquisition and processing of exact number. We address these questions through talks on three issues: 1) the basic psychophysical properties of numerical representations (Halberda, Burr), 2) how visual mechanisms integrate representations of number (Franconeri & Alvarez), and 3) how these representations support exact computation, both in standard linguistic representations (Frank) and via alternative representations (Barner). The issues addressed by our symposium have been a focus of intense recent interest. Within the last four years there have been a wide variety of high-profile reports from developmental, neuroscientific, comparative, and cross-linguistic/cross-cultural studies of number. Research on number is one of the fastest moving fields in cognitive science, due both to the well-defined questions that motivate research in this field and to the wide variety of methods that can be brought to bear on these questions. The target audience of our symposium is a broad group of vision scientists, both students and faculty, who are interested in connecting serious vision science with cognitive issues of broad relevance to a wide range of communities in psychology, neuroscience, and education. In addition, the study of number provides an opportunity to link innovations in vision research methods—including psychophysical-style experimental designs, precise neuroimaging methods, and detailed computational data analysis—with deep cognitive questions about the nature of human knowledge. We anticipate that attendees of our symposium will come away with a good grasp of the current state of the art and the outstanding issues in the interface of visual and numerical processing.

Herzog (Laboratory of Psychophysics, BMI, EPFL, Switzerland) Presenters: Doug Crawford (Centre for Vision Research, York University, Toronto, Ontario, Canada), David Melcher (Center for Mind/Brain Sciences and Department of Cognitive Sciences University of Trento, Italy), Patrick Cavanagh (LPP, Université Paris Descartes, Paris, France), Shin’ya Nishida (NTT Communication Science Labs, Atsugi, Japan), Michael H. Herzog (Laboratory of Psychophysics, BMI, EPFL, Switzerland) Symposium Summary Due to the movements of the eyes and those of the objects in the environment, natural vision is highly dynamic. An understanding of how the visual system can cope with such complex inputs requires an understanding of reference frames, used in the computations of various stimulus attributes. It is well known that the early visual system has a retinotopic organization. It is generally thought that the retinotopic organization of the early visual system is insufficient to support the fusion of visual images viewed at different eye positions. Moreover, metacontrast masking and anorthoscopic perception show that a retinotopic image is neither sufficient nor necessary for the perception of spatially extended form. How retinotopic representations are transformed into more complex non-retinotopic representations has been long-standing and often controversial question. The classical paradigm to study this question has been the study of memory across eye movements. As we shift our gaze from one fixation to another one, the retinotopic representation of the environment undergoes drastic shifts, yet phenomenally our environment appears stable. How is this phenomenal stability achieved? Does the visual system integrate information across eye movements and if so how? A variety of theories ranging from purely retinotopic representations without information integration to detailed spatiotopic representations with point-by-point information integration have been proposed. Talks in this symposium (Crawford, Melcher, Cavanagh) will address the nature of trans-saccadic memory, the role of extra-retinal signals, retinotopic, spatiotopic, and objectopic representations for information processing and integration during and across eye Vision Sciences Society 21 Member-Initiated Symposia movements. In addition to the challenge posed by eye movements on purely retinotopic representations, recent studies suggest that, even under steady fixation, computation of moving form requires non-retinotopic representations. This is because objects in the environment often move with complex trajectories and do not stimulate sufficiently retinotopically anchored receptive fields. Moreover, occlusions can “blank out” retinotopic information for a significant time period. These failures to activate sufficiently retinotopically anchored neurons, in turn, suggest that some form of non-retinotopic information analysis and integration should take place. Talks in this symposium (Nishida, Herzog) will present recent findings that show how shape and color information for moving objects can be integrated according to non-retinotopic reference frames. Taken together, the talks at the symposium aim to provide a recent perspective to the fundamental problem of reference frames utilized by the visual system and present techniques to study these representations during both eye movement and fixation periods. The recent convergence of a variety of techniques and stimulus paradigms in elucidating the roles of non-retinotopic representations provides timeliness for the proposed symposium. Since nonretinotopic representations have implications for a broad range of visual functions, we expect our symposium to be of interest to the general VSS audience including students and faculty.

Victor (Weill Medical College of Cornell University) Presenters: Sheila Nirenberg (Dept. of Physiology and Biophysics, Weill Medical College of Cornell University), Diego Contreras (Dept. of Neuroscience, University of Pennsylvania School of Medicine), Charles E. Connor (Dept. of Neuroscience, The Johns Hopkins University School of Medicine), Jeffrey D. Schall (Department of Psychology, Vanderbilt University) Symposium Summary The theme of the symposium is the importance of analyzing the time course of neural activity for understanding behavior. Given the very obviously spatial nature of vision, it is often tempting to ignore dynamics, and to focus on spatial processing and maps. As the speakers in this symposium will show, dynamics are in fact crucial: even for processes that appear to be intrinsically spatial, the underlying mechanism often resides in the time course of neural activity. The symposium brings together prominent scientists who will present recent studies that exemplify this unifying theme. 22 Vision Sciences Society VSS 2009 Program Their topics will cover the spectrum of VSS, both anatomically and functionally (retinal ganglion cell population coding, striate cortical mechanisms of contrast sensitivity regulation, extrastriate cortical analysis of shape, and frontal and collicular gaze control mechanisms). Their work utilizes sophisticated physiological techniques, ranging from large-scale multineuronal ex-vivo recording to intracellular in vivo recording, and employs a breadth of analytical approaches, ranging from information theory to dynamical systems. Because of the mechanistic importance of dynamics and the broad range of the specific topics and approaches, it is anticipated that the symposium will be of interest to physiologists and non-physiologists alike, and that many VSS members will find specific relevance to their own research.

Foster (University of Manchester, UK), Jakob H Macke (Max-Planck-Institut für biologische Kybernetik, Tübingen), Felix A. Wichmann (Technische Universität Berlin & Bernstein Center for Computational Neuroscience Berlin, Germany), Laurence T. Maloney (NYU) Symposium Summary A key step in vision research is comparison of experimental data to models intended to predict the data. Until recently, limitations on computer power and lack of availability of appropriate software meant that the researcher’s tool kit was limited to a few generic techniques such as fitting individual psychometric functions. Use of these models entails assumptions such as the exact form of the psychometric function that are rarely tested. It is not always obvious how to compare competing models, to show that one describes the data better than another or to estimate what percentage of ‘variability’ in the responses of the observers is really captured by the model. Limitations on the models that researchers are able to fit translate into limitations on the questions they can ask and, ultimately, the perceptual phenomena that can be understood. Because of recent advances in statistical algorithms and the increased computer power available to all researchers, it is now possible to make use of a wide range of computer-intensive para- VSS 2009 Program Member-Initiated Symposia metric and nonparametric approaches based on modern statistical methods. These approaches allow the experimenter to make more efficient use of perceptual data, to fit a wider range of perceptual data, to avoid unwarranted assumptions, and potentially to consider more complex experimental designs with the assurance that the resulting data can be analyzed. Researchers are likely familiar with nonparametric resampling methods such as bootstrapping (Efron, 1979; Efron & Tibshirani, 1993). We review a wider range of recent developments in statistics in the past twenty years including results from the machine learning and model selection literatures. Knoblauch introduces the symposium and describes how a wide range of psychophysical procedures (including fitting psychophysical functions, estimating classification images, and estimating the parameters of signal detection theory) share a common mathematical structure that can be readily addressed by modern statistical approaches. He also shows how to extend these methods to model more complex experimental designs and also discusses modern approaches to smoothing data. Foster describes how to relax the typical assumptions made in fitting psychometric functions and instead use the data itself to guide fitting of psychometric functions. Macke describes a technique---decision-images--- for extracting critical stimulus features based on logistic regression and how to use the extracted critical features to generate optimized stimuli for subsequent psychophysical experiments. Wichmann describes how to use “inverse” machine learning techniques to model visual saliency given eye movement data. Maloney discusses the mea- surement and modeling of super-threshold differences to model appearance and gives several examples of recent applications to surface material perception, surface lightness perception, and image quality. The presentations will outline how these approaches have been adapted to specific psychophysical tasks, including psychometric-function fitting, classification, visual saliency, difference scaling, and conjoint measurement. They show how these modern methods allow experimenters to make better use of data to gain insight into the operation of the visual system than hitherto possible.
