Book excerpt: Mark Eli Kalderon presents an original study in the philosophy of perception written in the medium of historiography. He considers the phenomenology and metaphysics of sensory presentation through the examination of an ancient aporia. Specifically, he argues that a puzzle about perception at a distance is behind Empedocles' theory of vision. Empedocles conceives of perception as a mode of material assimilation, but this raises a puzzle about color vision, since color vision seems to present colors that inhere in distant objects. But if the colors inhere in distant objects how can they be taken in by the organ of sight and so be palpable to sense? Aristotle purports to resolve this puzzle in his definition of perception as the assimilation of sensible form without the matter of the perceived particular. Aristotle explicitly criticizes Empedocles, though he is keen to retain the idea that perception is a mode of assimilation, if not a material mode. Aristotle's notorious definition has long puzzled commentators. Kalderon shows how, read in light of Empedoclean puzzlement about the sensory presentation of remote objects, Aristotle's definition of perception can be better understood. Moreover, when so read, the resulting conception of perception is both attractive and defensible.

Available in PDF, EPUB and Kindle. Book excerpt: In order to see the world as we do our visual system constantly performs many amazing feats that are largely unknown to us, the viewers. In order to create and update a seamless and coherent representation of the world, our eyes and brain have to deal with many obstacles that could interfere with object recognition such as occluding blood vessels in our eyes, layers of occluding retinal neurons, the blind spot that is devoid of photoreceptors, objects and shadows occluding other objects, and retinal inhomogeneities. Ultimately, we obtain information that encodes relative brightness and colors that allow us to recognize different objects and surfaces. How is it that we obtain the information to assign color to object surfaces? It has been hypothesized that we predominantly extract information about the color of an object from the spectral contrast at the edges and fill in the remaining areas (if the edge information is consistent with that from a uniform surface). These ideas have been put forth to explain striking visual illusions such as the Cornsweet Illusion, neon color spreading, and the watercolor effect. All of these illusions exist in both color and brightness domains. Thus, even though it may not be intuitively obvious, edges play a key role in our final percept of what color we see when viewing an object. It is said that we 'perceptually fill in' color from edges similarly to how our visual system fills in the blind spot in our eye. Of course it should be noted that spectral information may also be available from within the regions away from the edges and this information may also play an important role in the perception of surface color. The theory that edge information alone determines color and that internal surface information is discarded implies that there is no difference in neural computation of physical surface color and edge induced color spreading. Initial studies of this question suggest that illusory colors and actual surface colors may in fact show important differences. One goal of the present study is to employ both psychophysics and electrophysiology to determine under what conditions illusory colors and surface colors are differentiated to provide insights into the fundamental processes involved in surface color perception. If filling-in is indeed important for surface color perception, then how might color filling-in occur? One possibility is that information from the edges might be propagated in a feedforward manner that passively spreads until another edge or contradicting information is encountered. Another possibility is that edge information could be relayed to higher order form centers and then surface colors reconstructed from feedback from those higher regions. The question of feed-forward vs. feedback mechanisms of perception has been debated by scientists since at least the time of Hering and Helmholtz, Hering favoring a bottom up interpretation while Helmholtz argued that our visual system performs 'unconscious inferences.' It is currently appreciated that a relatively sparse sampling of visual information from the world results in a rich visual percept, supporting the idea that much of our vision is actually reconstructed from past experience. Another goal of the present study is to apply electrophysiological methods (hdEEG) to determine the relative importance of feed-forward and feedback mechanisms in surface color perception. This work expands on previous research which developed a method of measuring the watercolor illusion with single channel VEP. This dissertation provides a literature review of the background and significance of the problems, presents preliminary data, outlines the series of proposed experiments, and lastly the results of the proposed experiments.

Available in PDF, EPUB and Kindle. Book excerpt: Color has been studied for centuries, but has never been completely understood. Digital technology has recently sparked a burgeoning interdisciplinary interest in color. The fact that color is a quality of perception rather than a physical quality brings up a host of interesting questions of interest to both artists and scholars. This volume--the ninth in the Vancouver Studies in Cognitive Science series--brings together chapters by psychologists, philosophers, computer scientists, and artists to explore the nature of human color perception with the aim to further our understanding of color by encouraging interdisciplinary interaction.
