Charles Chubb, PhD, is a professor in the Department of Cognitive Sciences at the University of California at Irvine. He also holds the position of adjunct senior scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts. His research focuses on the computational basis of visual and auditory perception. His specific research interests include visual motion perception, texture perception, lightness and brightness perception, visual control of motor responses, camouflage, and also auditory perception of tonal variations. In addition, at the Marine Biological Laboratory in Woods Hole, he performs psychophysical experiments to analyze the visual processing performed by cuttlefish as they camouflage themselves in response to the visual properties of their surroundings. Dr. Chubb received his bachelor's degree in philosophy from Princeton University in 973. He then taught seventh and eighth grade English for years at the Friends Academy in Locust Valley, New York, returning to graduate school in 98 at New York University, from which he received his PhD in psychology in 985. After a postdoctoral fellowship with George Sperling at New York University, in 989 Dr. Chubb joined the psychology department at Rutgers, the State University of New Jersey, in New Brunswick, where he was a faculty member until moving to the cognitive sciences department at the University of California at Irvine in 99 . He is an associate editor for Attention, Perception amp amp Psychophysics and a topical editor for the Journal of the Optical Society of America A. Barbara A. Dosher, PhD, is a Distinguished Professor of Cognitive Sciences at the University of California, Irvine (UCI). She studies how humans perceive, remember, and retrieve information using a combination of behavioral testing and mathematical modeling. Her early research studied the speed and accuracy of retrieval from short-term memory and forgetting of both conscious and subconscious memories. Her recent work seeks to understand how attention and learning affect the accuracy of human perception and to develop quantitative models of state-dependent perceptual processes and visual memory. The National Science Foundation, the Air Force Office of Scientific Research, the National Institutes of Mental Health, and the National Eye Institute have funded her research. Dr. Dosher received her bachelor's degree in psychology from the University of California, San Diego, in 973 and her PhD in experimental psychology from the University of Oregon in 977. She was a professor of psychology at Columbia University from 977 to 992, when she joined the faculty of UCI in the Department of Cognitive Sciences. She is a member of the National Academy of Sciences, a fellow of the American Psychological Society and the Society for Experimental Psychologists, and is a past president of the Society for Mathematical Psychology. She is an elected member of the executive board of the Vision Sciences Society, was an associate editor for Psychological Review and has served on the editorial boards of journals in cognitive psychology and vision science. She has served as dean of the UCI School of Social Sciences since 2 2. Zhong-Lin Lu, PhD, obtained a BS in theoretical physics from the University of Science and Technology of China in 989 and a PhD under Samuel J. Williamson in physics at New York University ( 989 amp ndash 992). This was followed by a 4-year postdoctorate in cognitive science with George Sperling at University of California, Irvine. He joined the University of Southern California as an assistant professor in 99 and was appointed professor of psychology and biomedical engineering in 2 4 and William M. Keck Chair in Cognitive Neuroscience in 2 . In 2 , he joined the Ohio State University as Distinguished Professor of Social and Behavioral Science, professor of psychology, and director of Center for Cognitive and Behavioral Brain Imaging. Dr. Lu is a fellow of the Society of Experimental Psychologists and the Association for Psychological Science. The goal of Dr. Lu's research is to construct computational brain models for perception and cognition - models sufficiently computational such that they can be represented in a computer program or mathematical theory. Psychophysical experimentation, physiological investigation, clinical testing, and computational modeling are all essential ingredients and tools in his research. He has been actively engaged in the (a) computational and psychophysical study of visual and auditory perception, attention, and perceptual learning (b) functional brain imaging study of sensory and attentional processes, second language learning, and human decision making and (c) study of visual deficits in dyslexia, amblyopia and Alzheimer's disease. Since 99 , he has published two edited books, three special issues, 8 articles, and more than 2 abstracts. Richard M. Shiffrin, PhD, is Distinguished Professor and Luther Dana Waterman Professor at Indiana University, as well as professor of psychological and brain sciences, cognitive science, and statistics. He is also a member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society. He is the recipient of the Rumelhart Prize, William James Fellow Award, APA Distinguished Scientific Contribution Award, and the Society of Experimental Psychologists Warren Medal. He has published widely on human memory and information processing in journals such as Psychological Review and Psychonomic Bulletin and Review and in the book series The Psychology of Learning and Motivation.
