Visual Experience

Gary Hatfield has studied visual perception for more than three decades. His works include experimental studies of shape constancy, theoretical papers on perception, and philosophical studies of the fundamental concepts and theories of visual perception and cognition and their history. His work in the history and philosophy of psychology extends from the seventeenth century to current controversies on qualia and perceptual representation. He has published books on Descartes and the Meditations and The Natural and the Normative: Theories of Spatial Perception from Kant to Helmholtz, his essays have been collected in Perception and Cognition: Essays in the Philosophy of Psychology, and he has translated Kant's Prolegomena to Any Future Metaphysics. He is the co-founder of the Visual Studies undergraduate program at Penn and has co-taught, with psychologists and art historians, courses and seminars on all aspects of visual perception.Sarah Allred studies visual perception and memory through psychophysics, probabilistic computational models, and neurophysiology. She is also interested in the philosophy of perception and evolutionary psychology. This range of topics reflects her academic training: a BSc in Applied Physics in 1999, a PhD in Neurobiology and Behavior from the University of Washington in 2006, and postdoctoral work in the lab of David Brainard at the University of Pennsylvania. Since 2009, Sarah has been teaching and researching as an assistant professor in the psychology department at Rutgers, The State University of New Jersey. She is the recipient of an NSF Career Award (2010-4).
