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: Since , Sarah has been teaching and researching as an assistant professor in the psychology department at Rutgers, The State University of New Jersey. Oxford University Press is a department of the University of Oxford. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide.

Visual Experience Sensation, Cognition, and Constancy Edited by Gary Hatfield and Sarah Allred Contributors are interdisciplinary, so the book provides multiple perspectives on one issue Asks psychologists to move beyond their usual comfort zone in discussing methodological and philosophical questions.
This is done through engaging questions that many psychologists find interesting but are hesitant to discuss openly Asks philosophers to engage with the empirical literature of psychology more fully than usual. This shows the benefit to philosophy of engaging with the empirical sciences closely. In the ninth chapter, Olkkonen, Hansen and Gegenfurtner discuss why color vision is important and ecologically adaptive as a perceptual ability and suggest that color vision facilitates object discrimination while avoiding numerous and confounding possible perceptual states of the world.
Color constancy enables identification of a given object despite the variation in illumination. The authors introduce their novel experimental method for the memory color investigation which is the adjustment of stimulus color by the observer to avoid the possible confounding effects of color memory. Finally the authors of this chapter discuss the effects of prior knowledge of color appearance on object identification. At the beginning of the tenth chapter, Hilbert explores color constancy under different illuminations and claims that the phenomenology of color constancy is not stable.
The rest of the chapter gives a philosophical take on the limitations in the definition of concepts like computation, judgment and inference. In the eleventh chapter, Sarah Allred brings up the topic of ambiguity in color experience ambiguity in image formation, visual ambiguity due to the physiological properties of the photoreceptors and the existence of noise in the physiological system and suggests a Bayesian computational approach to the problem of sensory ambiguity and information loss.
Although they converge under a main topic, each chapter of this volume could be considered as a separate paper. Also, in some chapters, the reader is confronted with philosophical claims which seem hard to test and are non-falsifiable claims, aiming to answer the proximal mechanisms of perception e.
This volume represents the recent fundamental theories and findings concerning visual experience through the works of leading scholars and professionals of the field. The book is unique in the way that it shows the recent understandings in the philosophy of perception, which could be considered in line with the classic works such as Kant and Merleau-Ponty on perception. Essays in the Philosophy of Psychology Hatfield, , which is his perspectives on different aspects of vision from theoretical issues in visual perception and cognition to color perception.
Visual Experience: Sensation, Cognition, and Constancy - Oxford Scholarship
Due to the nature of the volume which is a discussion regarding the recent findings in visual experience with a focus on the philosophical point of view, it seems that the book is written mainly for the professionals of the field and does not seem to be an easy read for non-professionals and general readers. Visual Perception is therefore an essential resource for the professionals and researchers in the fields of visual perception, theory of mind and philosophy of science.
Essays in the philosophy of psychology. Current Issue Vol 14, No 4 If experience is not as of retinal stimulation proximal mode , but does not always exhibit constancy or at least not in all respects , how shall we describe this intermediate state? Also, should we regard any departure from constancy as a failure of the visual system, or might it be a reasonable or adaptive response?
Visual Experience: Sensation, Cognition, and Constancy
In what circumstances is seeing highly conditioned by cognitive factors such as background assumptions, and in what circumstances not? This volume focuses on size constancy and color constancy. It considers methodologies for studying conscious visual perception, efforts to describe visual experience in relation to constancy, what it means that constancy is not always perfect, and the conceptual resources needed for explaining visual experience.
