Some experiments in perceptual psychology measure perceivers’ phenomenal experiences of objects versus their cognitive assessments of object properties. Analyzing such experiments, this article responds to Pizlo’s claim that much work on shape constancy before 1985 confused problems of shape ambiguity with problems of shape constancy. Pizlo fails to grasp the logic of experimental designs directed toward phenomenal aspects of shape constancy. In the domain of size perception, Granrud’s studies of size (...) constancy in children and adults distinguish phenomenal from cognitive factors. (shrink)

This chapter reconsiders the notion of perceptual constancy from the ground up. It distinguishes the phenomenology of perceptual constancy and stability from a functional characterization of perception as aiming at full constancy. Drawing on this distinction, we can attend to the phenomenology of constancy itself, and ask to what extent human perceivers attain constancy, as usually defined. Within this phenomenology, I distinguish phenomenal presentations of spatial features and color properties from categorizations, conceptualizations, and judgments (...) that underlie verbal or other responses to those presentations. Although phenomenal presentation and categorization commonly co-occur, they are distinct aspects of experience. After reviewing several standard descriptions of constancy, I present laboratory findings and my own phenomenological descriptions by way of confirming that, although perception "tends toward" constancy, human perceivers do not usually attain full constancy for either spatial or chromatic properties (as many investigators acknowledge). For spatial perception, I find that the phenomenology has been systematically misdescribed, and I offer a more adequate description of the phenomenology of everyday spatial perception. However, my greatest quarrel with previous theory concerns the functional aim of the constancies. I argue not only that perception does not achieve full constancy but that we should not characterize it as aiming for full constancy. Rather, perception seeks a stability of representation suitable for guiding our actions and which can also, as needed, enable us to classify and re-identify objects by phenomenally presented properties such as shape, size, or color. Further, I argue that theorists should not confuse these classifications with the qualitative character of phenomenal experience. My arguments underscore the need to distinguish phenomenal representation (better, "presentation") from conceptual categorization, and to distinguish perceptual presentations from subsequent processes that are involved in responding to them.

In this outstanding introduction, Constance Meinwald covers all of Plato's philosophy and shows how he shaped the landscape of Western philosophy. Beginning with a helpful overview of what is known about Plato's life and times, she clearly explains and assesses Plato's fundamental arguments and ideas. These include the importance of Plato's view of what philosophy is and the distinctive way in which his most important arguments are presented in dialogues; his theories of ethics addressed through the fundamental and enduring questions (...) happiness and virtue; his influential treatments of the soul and immortality; the lasting contributions he made to the study of metaphysics and the nature of knowledge through his theory of the Forms; and his enduring and controversial insights into political and social thought in the context of his theories of human nature. Throughout, Constance Meinwwald draws expertly on Plato's most important dialogues to present a thorough and lively picture of his philosophy. Essential reading for students of ancient philosophy and Classics, Plato is an ideal introduction to arguably the greatest of all Western philosophers. (shrink)

This study aims to further investigate the convergent validity of the recently-proposed metapersonal model and measure of self-construal, and to emphasize the discriminant validity of the metapersonal self-construal as a distinct construct, capturing a unique aspect of self-construal separate from either interdependent or independent aspects. The study looked at two questions: Does the metapersonal self-construal predict higher emotional intelligence? Do those who have higher metapersonal self-construal scores also report greater well-being? A group of 212 undergraduate students was assessed using (...) a self-construal scale that includes the new measure of metapersonal self-construal, along with scales measuring emotional intelligence and well-being. The metapersonal self-construal predicted higher emotional intelligence scores and greater well-being than either the independent or interdependent self-construals. (shrink)

Tengelyi, so the author‘s research approach, mainly refers to traditional patterns, when he tries to say what the structure of the world might be. She considers Welt und Unendlichkeit (World and Infinity) a history of philosophy, revealing the sources of Tengelyi‘s inspirations. The author puts a focus on the „diakritische Differenz“(diacritical difference) and the „heterologisches Prinzip“ (heterological principle) as Tengelyi‘s propositions of a dynamic formation of the world. Even though the philosophical terms in ancient Greek and Latin reveal Tengelyi‘s tendency (...) to unambiguousness. The author contends that Tengelyi does not recognize rhetorical figures as possible schemes of the openess of the world (Weltoffenheit) and that he therefore misses a vital phenomenological aspect.

To many Sartreans, these accounts of the common physical and psychological responses to trauma reflect a familiar view of the self. For Sartre, the self is not an unchanging, underlying essence that guarantees personal identity over time; rather, it is an ongoing project that is founded on our being-in-the-world as embodied freedom, on our concrete relations with others, and, I would add, on our emotions. It thus appears that feminist writings on the effects of sexual trauma could benefit greatly from (...) a careful reading or rereading of Sartrean ontology, even though Sartre himself has not, to my knowledge, related any aspect of his philosophy specifically to the problem of trauma. With this in mind, this essay attempts to work out, within the broader Sartrean ontological framework, a preliminary outline of a phenomenology of rape trauma, one that is based on a feminist consideration of Sartre's distinct but intertwined theories of freedom, embodiment, and the emotions. In this endeavor, an important point I hope to bring out is that even though Sartre has at best provided a rough sketch for his theory of the emotions, we can nevertheless glean from that sketch valuable insights that can both inform and illuminate our understanding of the effects of trauma.

This volume, edited by three leading proponents and practitioners of human science psychology, serves as an invitation to readers new to this approach while also renewing that invitation to those who have long embraced and advanced research in the field from this perspective. It is a timely and important invitation. In 2009, the American Psychological Association declared psychology to be a core STEM (science, technology, engineering, mathematics) discipline and advocated the teaching and practice of psychology with this natural science understanding (...) in mind, but in 2014 further reaffirmed alternative methods by adding a new journal, Qualitative Psychology. The varied essays in this volume, certainly, bolster the view that a purely STEM-centered vision would ignore much about the very experience of being human.In fact, it would be dangerous to rely solely on the methods of the natural sciences to study human beings, who operate in the realm of meanings, lived experience, and complex and complicated relationships with self and others. We create societies and belief systems, orient ourselves in time, experience beauty and pain. The Qualitative Vision for Psychology: An Invitation to a Human Science Approach argues that because we have aspects that are distinctly and uniquely human -- we are not rats, hydrogen, or rocks, for example -- this necessitates a distinctly human science, one that regards persons as humans rather than objects of study. The laws and formulas of the natural sciences simply do not take into account that particularly human way of being in the world.There are few comprehensive books on psychology conceived as a human science, even though it has a long history with roots in phenomenology, existentialism, psychoanalysis, humanistic psychology, and hermeneutics. In recent years, as these essays discuss, the field has been transformed through its contact with feminism, critical historical analysis, and deconstruction, and it has continued to examine new challenges. Further, we see here its specific applicability to issues as diverse as empathy, cultural history, apartheid, sexual assault, fetishes, and our natural environment. (shrink)

</b>This commentary focuses on shape constancy in vision and its relation to sensorimotor knowledge. I contrast “Protean” and “Constancian” views about how to describe perspectival changes in the appearance of an object’s shape. For the Protean, these amount to changes in apparent shape; for Constance, things are not merely judged, but literally appear constant in shape. I give reasons in favor of the latter view, and argue that Noë’s attempt to combine aspects of both (...) views in a “dual aspect” account does not manage to avoid an unacceptable attribution of contradictory content to visual appearance. I argue also that my position here actually fits better with Noë’s critique of a “snapshot” conception of visual appearance than his own interpretation of visual constancy, and better supports his claim that experiential content is constituted by the exercise of sensorimotor understanding.

Recent neuroscience research makes it clear that human biology is cultural biology - we develop and live our lives in socially constructed worlds that vary widely in their structure values, and institutions. This integrative volume brings together interdisciplinary perspectives from the human, social, and biological sciences to explore culture, mind, and brain interactions and their impact on personal and societal issues. Contributors provide a fresh look at emerging concepts, models, and applications of the co-constitution of culture, mind, and brain. Chapters (...) survey the latest theoretical and methodological insights alongside the challenges in this area, and describe how these new ideas are being applied in the sciences, humanities, arts, mental health, and everyday life. Readers will gain new appreciation of the ways in which our unique biology and cultural diversity shape behavior and experience, and our ongoing adaptation to a constantly changing world. (shrink)

This paper develops an appearance view of perception (focusing on vision). When we see an object, we see it by having it appear some way to us. We see the object, not the appearance; but we see the object via the appearance. The appearance is subjectively conditioned: aspects of it depend on attributes of the subject. We mentally have the appearance and can reflect on it as an appearance. But in the primary instance, of veridical perception, it is the (...) object that we focus on and experience. I contrast this view with naive realism (sometimes called disjunctivism) (Brewer, Campbell, Noe) and with intentionalist or representationalist views, which I call the physical content view (Dretske, Tye, Crane, Hill, Burge). I agree with these views in rejecting sense-data intermediaries and in affirming direct perception, but I argue that direct perception occurs via appearances, making mine a critical direct realism. The other views attempt to explain the spatial content of perception (shape, size, distance) entirely through the physical properties of objects and their physical relation to the perceiver (viewing position). I argue instead that there are ineliminably subjective aspects of normal spatial perception, which are systematically manifested as a lack of full phenomenal constancy. This systematic underconstancy can’t be accounted for at all by a consistent naive realism; for the physical content view, it requires that most of our ordinary perception is classified as illusory, violating the spirit of that view. Accepting phenomenal underconstancy as pervasive, I suggest that our ability to perceive the mind-independent properties of objects depends on developed conceptual abilities. In the final section, I compare my appearance view with the adverbialism of Chisholm and the critical direct realism of Roy Wood Sellars. (shrink)

The puzzle of cross-modal shape experience is the puzzle of reconciling the apparent differences between our visual and haptic experiences of shape with their apparent similarities. This paper proposes that we can resolve the cross-modal puzzle by reflecting on another puzzle. The puzzle of perspectival character challenges us to reconcile the variability of shape experience through shifts in perspective with its constancy. An attractive approach to the latter puzzle holds that shape experience is complex, involving (...) both perspectival aspects and constant aspects. I argue here that parallel distinctions between perspectival and constant aspects of shape experience arise in sight and touch, and that perspectival aspects are modality-specific while at least some constant aspects are constitutively multisensory. I then address a powerful challenge to the idea that aspects of spatial phenomenology are shared cross-modally. (shrink)

Students of perception have long known that perceptual constancy is an important aspect of our perceptual interaction with the world. Here is a simple example of the phenomenon concerning color perception: there is some ordinary sense in which an unpainted ceramic coffee cup made from a uniform material looks a uniform color when it is viewed under uneven illumination, even though the light reflected by the shaded regions to our eyes is quite different from the light reflected by the (...) unshaded regions to our eyes (see figure 1). Or consider this example concerning size perception: there is some ordinary sense in which two telephone poles look the same size when the first is viewed from 100 meters and when the second is viewed from 1 meter, even though the visual angle subtended by the two poles on our retinae is very different (see figure 2). Or consider this example concerning shape perception: there is some ordinary sense in which a penny looks round both when viewed head on and when viewed from an acute angle, even though the area projected by the penny onto our retinae under these two conditions is very different (see figure 3). Or, finally, consider this example concerning auditory volume perception (which I cannot depict graphically): there is some ordinary sense in which a speaker’s voice sounds the same volume when heard from across the room and when heard from a distance of 1 meter, even though the energy striking our ears under these two conditions is very different.

This article proposes an account of color constancy based on an examination of the relevant scientific literature. Differences in experimental settings and task instructions that lead to variation in subject performance are given particular attention. Based on the evidence discussed, the core of the proposal made is that there are two different forms of color constancy, one phenomenal and the other projective. This follows the hypothesis of Reeves et al. (Perception & Psychophysics 70:219–228, 2008). Unlike Reeves et (...) al. (Perception & Psychophysics 70:219–228, 2008), it is argued that projective color constancy is crucially dependent upon phenomenal color constancy and certain aspects of scene perception. Additionally, it is hypothesized that capacities that support projective color constancy have an important role to play in facilitating our ability to quickly recognize scenes with diagnostic chromatic properties independently of assignments of colors to object surfaces.

This chapter provides an overview of the phenomenology of size perception and the use of instructions to tease apart phenomenal and cognitive aspects. It develops his own recent proposals concerning the geometry of visual space. The chapter proposes that visual space is contracted along the lines of sight. This contraction would explain the apparent convergence of railway tracks, but without invoking a “proximal mode” experience. Parallel railway tracks receding into the distance project converging lines onto the retinas. A (...) true proximal mode representation would show these lines converging as if in a vertical plane. But we experience them as converging while also receding in depth along the ground. The chapter suggests that this calls for a third geometry of visual space, intermediate between a linear perspective projection and full phenomenal constancy. The chapter attributes reports of full constancy to cognitive factors. size perception, visual space, geometry, lines of sight, proximal mode, phenomenal constancy. (shrink)

When you look at a circular plate at an angle, it looks circular. But there also is a certain sense in which its look can be described as oval. When you move, the plate’s look changes with your perspective on it—nevertheless, it continues to look circular. This chapter investigates whether these “constancy in variation” phenomena can be explained in terms of the representational content of visual experience, and whether constancy in variation provides special, phenomenological, reasons to construe experience (...) as having centered contents. Concentrating on shape, it argues that due to warring phenomenological demands, all views construing constancy in variation as representation of both objective and perspectival properties or features have limited explanatory powers, and that centering does not provide any advantage. By contrast, adopting the non-standard intentionalism called phenomenal intentionalism, we get rather natural explanations of the phenomenology of constancy in variation. (shrink)

In this chapter, data concerning the development of principal aspects of vision is reviewed. First, the development of colour vision and luminance perception is discussed. Relevant data accumulated so far indicates that perception of colour and luminance is present by 6-9 months of age. The presence of typical color illusions at this age suggests that the phenomenal character of color experience is comparable to that of adults well before the first birthday. Thus it seems plausible that color perception (...) develops on the grounds of genetically preprogrammed maturation, in which perceptual learning and plasticity play a limited role. This claim also seems to be supported by case studies of newly sighted patients. On the other hand, perceptual integration of edges and forms in the visual environment as well as the development of binocular vision, and the perception of ambiguous figures seem to depend crucially on early perceptual learning. Both developmental and clinical data indicate a more significant involvement of perceptual learning in such mid-level and higher level perceptual phenomena. (shrink)

How the Body Shapes the Mind is an interdisciplinary work that addresses philosophical questions by appealing to evidence found in experimental psychology, neuroscience, studies of pathologies, and developmental psychology. There is a growing consensus across these disciplines that the contribution of embodiment to cognition is inescapable. Because this insight has been developed across a variety of disciplines, however, there is still a need to develop a common vocabulary that is capable of integrating discussions of brain mechanisms in neuroscience, behavioural expressions (...) in psychology, design concerns in artificial intelligence and robotics, and debates about embodied experience in the phenomenology and philosophy of mind. Shaun Gallagher's book aims to contribute to the formulation of that common vocabulary and to develop a conceptual framework that will avoid both the overly reductionistic approaches that explain everything in terms of bottom-up neuronal mechanisms, and inflationistic approaches that explain everything in terms of Cartesian, top-down cognitive states. Gallagher pursues two basic sets of questions. The first set consists of questions about the phenomenal aspects of the structure of experience, and specifically the relatively regular and constant features that we find in the content of our experience. If throughout conscious experience there is a constant reference to one's own body, even if this is a recessive or marginal awareness, then that reference constitutes a structural feature of the phenomenal field of consciousness, part of a framework that is likely to determine or influence all other aspects of experience. The second set of questions concerns aspects of the structure of experience that are more hidden, those that may be more difficult to get at because they happen before we know it. They do not normally enter into the content of experience in an explicit way, and are often inaccessible to reflective consciousness. To what extent, and in what ways, are consciousness and cognitive processes, which include experiences related to perception, memory, imagination, belief, judgement, and so forth, shaped or structured by the fact that they are embodied in this way?

I argue for the following claims: (1) A core Husserlian account of perceptual constancy needs to be given in terms of indicative future-oriented conditionals but can be complemented by a counterfactual account; (2) thus conceived, constancy is a necessary aspect of content. I speak about a “core Husserlian” account so as to capture certain ideas that Michael Madary has presented as the core of Edmund Husserl's approach to perceptual constancy, viz., that “perception is partly constituted by the (...) continuous interplay of intention and fulfilment” and that this “gives us a way to understand the relationship between different appearances of the same object” (See Madary, M. (2012) “Husserl on Perceptual Constancy.” European Journal of Philosophy 20(1): 145–165.). I take myself to be developing, and perhaps correcting, Madary's view as I discuss the role of the core Husserlian ideas, and counterfactuals, in accounting for shape and color constancy, respectively. I bridge constancy and fulfilment-conditional content by appealing to the Husserlian notion of constitution, which captures the process in which objectivity and, correlatively, intentional experience, are built up in the experiential flow.

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various (...) levels feature in the content of perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

Synchronic and diachronic unity of consciousness and their in­terrelation pose interdisciplinary problems that can only be addressed by the combined means of philosophical and scien­tific theories. In the first part of the article the author briefly reviews psychological and materialistic accounts of personal identity. Historically these accounts were introduced to solve the problem of diachronic identity of persons, i.e., the problem of their persistence through time. She argues that they don’t explain how synchronic unity of consciousness, subjectively experienced as the (...) unity of the phenomenal field, correlates with diachronic identity of persons. In the second part of the article the author reviews Tim Bayne’s “virtual phenomenalism”. In the third part of the article she formulates two questions that virtual phenomenalism has to answer in order to solve the problems that face both the psychological and the materialistic accounts of personal identity. The first question concerns some cognitive and neurobiological characteristics of consciousness that Bayne invokes in order to propose an original solution of the problem of the synchronic unity of consciousness. It might be asked whether the same characteristics can undermine Bayne’s solution of the problem of the diachronic unity of consciousness. The second question is a development of Bernard Williams’ arguments against psychological accounts of personal identity. The author suggests that similar arguments can be used against virtual phenomenalism. (shrink)

Sometimes when we describe our own sensory experiences we seem to attribute to experience itself the same sorts of familiar properties – such as shape or colour – as we attribute to everyday physical objects. But how literally should we understand such descriptions? Can there really be phenomenal elements or aspects to an experience which are, for example, quite literally square? This paper examines how these questions connect to a wide range of different commitments and theories about (...) the metaphysics of mind. In particular, I consider whether there may be phenomenological reasons to accept or reject the idea that there are elements or aspects of conscious experience itself which instantiate familiar spatial properties. I also explore how some general theses about the nature of empirical properties can motivate different answers to these questions. (shrink)

The paper examines some of the many factors that influence the shape of designed products in the mechanical engineering industries. It is shown that, once the detailed shape of a product has been determined, the analysis of that shape from the viewpoints of various engineering activities downstream of design leads to a range of inherently different perceptions of it.

Seeing happens effortlessly and yet is endlessly complex. Among the most fascinating aspects of visual perception is its stability and constancy. As we shift our gaze or move about the world, the light projected onto the retinas is constantly changing. Yet the surrounding objects appear stable in their properties. Psychologists have long been interested in the constancies. They have asked questions such as: How good is constancy? Is constancy a fact about how things look, or is (...) it a product of our beliefs and judgments about how things look? How can the contents of visual experience be studied experimentally? Philosophers have long been interested in characterizing visual experience and have become widely interested in the constancies more recently. As psychologists and philosophers have interacted, new questions have arisen: 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? In what circumstances is seeing highly conditioned by cognitive factors such as background assumptions, and in what circumstances not? Our 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.

The study addresses some aspects of Suprematist theory of perception, allowing to investigate the structure of Suprematist phenomenon in the context of ontology, socio-political and religious-mystical works of K. Malevich. The aim of the paper is to present Malevich’s theory of perception in the framework of enactivism. Namely, the article focuses on the theory of social affordances, which today is widely used in design, game development and other everyday practices. The author refers to Malevich’s theoretical and sociopolitical essays, as (...) well as to the commentary literature. Although Suprematism represents a well-researched tradition in art theory, the author stress the need for a follow-up study of Malevich’s theoretical essays in the contemporary context of philosophy of consciousness. The author also emphasizes the relevance of Suprematist philosophy for today’s way of thinking. For the most authentic presentation of Malevich’s ideas I use the phenomenological and hermeneutical method on a par with elements of the ecological approach in psychology and enactivism in the philosophy of consciousness. Consequently, the theory of affordances an effective and natural unification of all the aspects discussed above. The study shows the affinity of Malevich’s ideas to this theory. The author focused on the thesis of feeling as the goal of the expressive act of art. As one could see, Kazemir Malevich always emphasized the bodily-affective dimension of art, and in this sense he participated in a global cultural-historical shift in our conception of the essence of art. Since then, art has ceased to be elitist, but has instead inherited everyday practices. Thus, Malevich speaks of a new art that suits the man of the new world, the Soviet citizen. In this context, I relate the idea of affordance, which means the creation of a feeling-opportunity for subjective action (agency), to the artistic act whose goal, according to Malevich, is the creation of an emotional body-affective feeling. I defend the theory of social affordances, explaining the mechanism of social interaction, as the most adequate model for explaining Suprematism. As a result, based on the already developed concept of bodily-affective dynamics, I show how visionary and creative Malevich was, and how his ideas contribute to the development of a theory of social, emotional affordances.

A coin rotating back in depth in some sense presents a changing, elliptical shape. How are we to understand such (in this case) ‘appearances of ellipticality’? How is the experiential sense of such shifting shape appearances related to the experiential sense of enduring shape definitive of perceived shape constancy? Is the experiential recovery of surface shape based on the prior (perhaps more fundamental) recovery of point or element 3D spatial locations?—or is the perception of (...) shape a largely independent perceptual achievement? Do we gain access to enduring shape properties by first detecting and working from ‘shape appearances’? These are some of the topics taken up in this paper. (shrink)

I show that the mathematical description of opponent-colors theory is identical to the mathematical description of two-state quantum systems in a mixed state. Based on the dual-aspect theory of phenomenal consciousness, which suggests that one or more physical entities in our universe have phenomenal aspects that are dual to their physical aspects and therefore predicts an exact correspondence between a system’s phenomenal states and the objective states of its underlying physical substrate, I hypothesize that color (...) sensations are phenomenal dual aspects of two-state quantum systems in a mixed state. Since nothing in this hypothesis suggests that what brings about the phenomenal experience that is dual to two-state quantum systems is the two-dimensionality of these systems, it is natural to generalize this hypothesis and suggest that other types of phenomenal experience (e.g., taste, odor, sound) are phenomenal dual aspects of quantum systems of higher dimensionalities. Finally, I propose that the two-state quantum systems that give rise to color in the brain are two-state ion-channels. (shrink)
