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)

In his interesting discussion of Mr. C. B. Martin's Mind article “A Religious Way of Knowing,” Mr. W. D. Glasgow ;“Knowledge of God”), agrees with Martin that emotions and feelings are part of what we call an aesthetic experience, and also that emotions and feelings are part of what we call a religious experience. “In this sense, at any rate,” Glasgow writes, “there is an analogy between aesthetic experience and religious experience. But...” he goes on, “are aesthetic statements more than (...) statements about emotions and feelings? Are statements about religious experience anything more than statements about emotions and feelings? A person could accept the analogy and yet maintain that for him aesthetic judgments have an objective reference. In this case the analogy confirms rather than destroys the existential claim of the theologian.”. (shrink)

Religion and spirituality seem to be very important for HIV-positive patients believers. Indeed, a recurring number of studies show strong correlations between religiosity/spirituality of individuals and different dimensions of health. The majority of these studies show most positive associations of religiosity/spirituality to physical health through reducing emotional distress, reduced rates of depression, greater optimism, better psychological adjustment, better preservation of CD4 cells, better control of viral load. The objective of this research is to understand the nature of the relationship between (...) religiosity and emotional health among HIV-positive patients, migrants from sub-Saharan Africa. Religiosity, the frequency of depressive episodes and subjective health 81 asymptomatic HIV patients regularly followed, were evaluated. Regression models and mediation, backed by a resampling procedure were tested. From mediation analyzes, the results show that through the mediating effect of subjective health, religiosity explains a decrease in the number of depressive episodes in people with HIV migrants from sub-Saharan Africa.

People categorize objects slowly when visual input is highly impoverished instead of optimal. While bottom-up models may explain a decision with optimal input, perceptual hypothesis testing (PHT) theories implicate top-down processes with impoverished input. Brain mechanisms and the time course of PHT are largely unknown. This event-related potential study used a neuroimaging paradigm that implicated prefrontal cortex in top-down modulation of occipitotemporal cortex. Subjects categorized more impoverished and less impoverished real and pseudo objects. PHT theories predict larger impoverishment effects for (...) real than pseudo objects because top-down processes modulate knowledge only for real objects, but different PHT variants predict different timing. Consistent with parietal-prefrontal PHT variants, around 250 ms, the earliest impoverished real object interaction started on an N3 complex, which reflects interactive cortical activity for object cognition. N3 impoverishment effects localized to both prefrontal and occipitotemporal cortex for real objects only. The N3 also showed knowledge effects by 230 ms that localized to occipitotemporal cortex. Later effects reflected (a) word meaning in temporal cortex during the N400, (b) internal evaluation of prior decision and memory processes and secondary higher-order memory involving anterotemporal parts of a default mode network during posterior positivity (P600), and (c) response related activity in posterior cingulate during an anterior slow wave (SW) after 700 ms. Finally, response activity in supplementary motor area during a posterior SW after 900 ms showed impoverishment effects that correlated with RTs. Convergent evidence from studies of vision, memory, and mental imagery which reflects purely top-down inputs, indicates that the N3 reflects the critical top-down processes of PHT. A hybrid multiple-state interactive, PHT and decision theory best explains the visual constancy of object cognition. (shrink)

Hilde Lindemann’s Holding and Letting Go is a valuable addition to the literature on personhood and identity. Like most such texts, it recognizes the ambiguity of the concepts. However, while other texts then try to clarify and fix the ambiguity, Lindemann goes in another direction. She embraces it by presenting and examining the many ways in which practices of social connection, interaction, and disconnection shape, preserve, and even damage an individual’s personal and social identity.Lindemann breaks with classic texts on identity, (...) which tend to move from the particular to proposing and supporting a specific definition of an objective concept of identity, usually incorporating moral agency.

Numerous recent discoveries in China of ancient tombs have greatly increased our knowledge of ritual and religious practices. These discoveries include excavated oracle bones, bronze, jade, stone and pottery objects, and bamboo manuscripts dating from the twelfth to fourth century BCE. Inscribed upon these artifacts are a large number of records of numerical sequences, for which no explanation has been found of how they were produced. Structural links to the Book of Changes, a divination manual that entered the Confucian canon, (...) are evident; yet, the algorithm described therein dates to the slightly later second to first century BCE. By combining archeological and statistical evidence, we propose a new methodology that enables us to reconstruct and test cleromantic techniques which can explain how these numerical sequences were generated. Dice and divination stalk use, either in combination or separately, appear in fact to have been underlying the rather stable numerical patterns in ancient China all the way back to the late Shang dynasty (1300–1046 BCE). Bringing to light such a long-standing technique, which awaits further confirmation from the ever-growing database of newly discovered numerical and textual records, can change drastically our understanding of early Chinese history and of the historical development of sophisticated arithmetical practices and the rationalization of chance.

This essay deals with the terms “form” and “function” as well as their relationship insofar as they are still used in philosophical and design-theory discourse to determine the aesthetic dimension of designed artefacts, especially of everyday objects, and often also to distinguish them from objects of art. I discuss whether our common understanding of these terms and their relationship is an appropriate instrument for such determinations. What is up for discussion here are not only conceptions of functional beauty with regard (...) to design methodology and the philosophical discourse on aesthetics, in which form and function become thematic, but also basic concepts of philosophical aesthetics itself. It is shown that the philosophical understanding of design aesthetics and the concepts of form and function are determined by profound preliminary decisions that restrict our access to the aesthetic dimension of designed artefacts, and a conceptualisation of an initial change in thinking is proposed.

Can young children such as 3-year-olds represent the world objectively? Some prominent developmental psychologists—such as Perner and Tomasello—assume so. I argue that this view is susceptible to a prima facie powerful objection: To represent objectively, one must be able to represent not only features of the entities represented but also features of objectification itself, which 3-year-olds cannot do yet. Drawing on Burge's work on perceptual constancy, I provide a response to this objection and motivate a distinction between three different (...) kinds of objectivity. This distinction helps advance current research on both objectivity and teleological action explanations in young children. (shrink)

This article shows that in 1.4.2.15-24 of the Treatise of Human Nature, Hume presents his own position on objects, which is to be distinguished from both the vulgar and philosophical conception of objects. Here, Hume argues that objects that are effectively imagined to have a “perfect identity” are imagined due to the constancy and coherence of our perceptions (what we may call ‘level 1 constancy and coherence’). In particular, we imagine that objects cause such perceptions, via what I (...) call ‘indirect causation.’ In virtue of imagining ideas of objects that have a perfect identity, our perceptions seem to be even more constant and coherent (what we may call ‘level 2 constancy and coherence’). Thus, in addition to seeing that Hume is presenting his own position on objects in this section of the Treatise, we see that he is working with a previously unrecognized kind of causation, i.e., indirect causation, and that he has two kinds of constancy and coherence in mind: level 1 and level 2.

Perceptual constancy, often defined as the perception of stable features under changing conditions, goes hand in hand with variation in how things look. A white wall in the orange afternoon sun still looks white, though its whiteness looks different compared with the same wall in the noon sun. Historically, this variation has often been explained in terms of our experience of “merely sensory” or subjective properties – an approach at odds with the fact that the variation does track objective (...) features of the perceptual situation, such as illumination. One approach, becoming more common, is to account for the variation in terms of further “dimensions” to perceptual experience. Especially in colour perception, this is a natural thought to have but the idea is often left vague. In this paper I argue that the “dimensional” strategy has problems of its own, but is useful in drawing out some interesting complications in the way perceptual experience is structured. Specifically, the structure of “constancy spaces” brings out the different ways in which there is stability and instability in the experience of constancy, without the need for novel or merely subjective features. Instability arises in a contingent structural feature of perceptual experience. (shrink)

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.

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.

There is nothing in this World constant but Inconstancy. [Swift 1711: 258] In this paper I argue that two standard characterizations of colour constancy are inadequate to the phenomenon. This inadequacy matters, since, I contend, philosophical appeals to colour constancy as a way of motivating illumination-independent conceptions of colour turn crucially on the shortcomings of these characterizations. After critically reviewing the standard characterizations, I provide a novel counterfactualist understanding of colour constancy, argue that it avoids difficulties of (...) its traditional rivals, and defend it from objections. Finally, I show why, on this improved understanding, colour constancy does not have the philosophical consequences that have been claimed for it in the literature. (shrink)

In this essay, we draw on John Haugeland’s work in order to argue that Burge is wrong to think that exercises of perceptual constancy mechanisms suffice for perceptual representation. Although Haugeland did not live to read or respond to Burge’s Origins of Objectivity, we think that his work contains resources that can be developed into a critique of the very foundation of Burge’s approach. Specifically, we identify two related problems for Burge. First, if (what Burge calls) mere sensory responses (...) are not representational, then neither are exercises of constancy mechanisms, since the differences between them do not suffice to imply that one is representational and the other is not. Second, taken by themselves, exercises of constancy mechanisms are only derivatively representational, so merely understanding how they work is not sufficient for understanding what is required for something, in itself, to be representational (and thereby provide a full solution to the problem of perceptual representation).

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4,000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sameness of material appearance or sameness of hue and saturation or judging an objective property—that is, whether its (...) change of color originated from a change in material or only from a change in illumination. Average color constancy indices were high for material appearance ratings and binary judgments of origin and low for hue–saturation ratings. Individuals’ performance varied, but judgments of material and of hue and saturation remained demarcated. Observers seem able to separate phenomenal percepts from their ontological projections of mental appearance onto physical phenomena; thus, even when a chromatic change alters perceived hue and saturation, observers can reliably infer the cause, the constancy of the underlying surface spectral reflectance.

At first pass, colour constancy occurs when one sees a thing in one’s environment to have a stable colour despite differences in the way it is illuminated. The phenomenon is intuitively grounded for example in everyday experiences in which something is partly shadowed but, in some sense, looks to be uniformly coloured. After a brief introduction to the colour constancy concept (§0) and the science of colour constancy (§1), my focus is on the significance of colour (...) class='Hi'>constancy for two intertwined philosophical issues. The first is colour ontology, where constancy has been used to argue for the objectivity of colour, and in particular for a reductive form of it (see §2). The second is colour constancy’s complicated connection to colour experience and colour epistemology. Colour constancy is a subtle phenomenon: it is situated at the intersection of perceptual experience and judgement; it is influenced by myriad forces within our visual-cognitive systems; and is likely a composite of interestingly disparate phenomena. I approach this suite of issues from the perspective of the given in colour perception (§3). As will become plain, the ontological and epistemic issues are related in important ways. This does not, however, detract from the value of focusing on each individually. (shrink)

Shepard claims that color constancy needs linear basis-function spectra, and infers the illuminant before removing its dependency. However, of the models of color constancy that have exact (and reasonable) spectral regimes, some do not need linear basis-function expansions of reflectance and illuminant spectra, some do not solve for the illuminant, and some estimate only partial object-reflectance information for single or multiple objects.

In this journal, Schulte develops a novel solution to the problem of distal content: by virtue of what is a mental representation about a distal object rather than a more proximal cause of that representation? Schulte maintains that in order for a representation to have a distal content, it must be produced by a constancy mechanism, along with two other conditions. I raise three objections to his solution. First, a core component of Schulte's solution is just a restrictive (...) version of Dretske's solution, but Schulte gives no argument for his restriction. Second, his proposed solution to a disjunction problem is ad hoc. Finally, his ‘far-out’ version of the distality problem is not a version of the distality problem at all. I conclude that Dretske's solution is preferable to Schulte's. (shrink)

Loosely put, colour constancy for example occurs when you experience a partly shadowed wall to be uniformly coloured, or experience your favourite shirt to be the same colour both with and without sunglasses on. Controversy ensues when one seeks to interpret ‘experience’ in these contexts, for evidence of a constant colour may be indicative a constant colour in the objective world, a judgement that a constant colour would be present were things thus and so, et cetera. My primary aim (...) is to articulate a viable conception of Present Constancy, of what occurs when a constant colour is present in experience, despite the additional presence of some experienced colour variation (e.g., correlating to a change in illumination). My proposed conception involves experienced colour layering – experiencing one opaque colour through another transparent one – and in particular requires one of those experienced layers to remain constant while the other changes. The aim is not to propose this layering conception of colour constancy as the correct interpretation of all constancy cases, but rather to develop the conception enough to demonstrate how it could and plausibly should be applied to various cases, and the virtues it has over rivals. Its virtues include a seamless application to constancy cases involving variations in filters (e.g., sunglasses) and illuminants; its ability to accommodate experiences of partial colours and error-free interpretations of difficult cases; and its broad theoretical-neutrality, allowing it to be incorporated into numerous perceptual epistemologies and ontologies. If layered constancy is prevalent, as I suspect it is, then our experiential access to colours is critically nuanced: we have been plunged into a world of colour without being told that we will rarely, if ever, look to a location and experience just one of them.

The phenomenon of size constancy is defined as the apparent perceptual invariance of the linear dimensions of a seen object as this approaches the eye or recedes from it. It has been interpreted as resulting from the application by the brain of a size correction, made possible by the subject's apprehension of distance cues present in the image. We present several observations which, by dissociating accommodation from distance of the seen object and by suppressing the optic effects (...) of accommodation on the visual image itself, show that this interpretation is incorrect, and that in fact the size correction of the visual image is a function of the central effort of accommodation, not of the distance of the seen object.

All representationalists maintain that there is a necessary connection between an experience’s phenomenal character and intentional content; but there is a disagreement amongst representationalists regarding the nature of those intentional contents that are necessarily connected to phenomenal character. Russellian representationalists maintain that the relevant contents are composed of objects and/or properties, while Fregean representationalists maintain that the relevant contents are composed of modes of presentation of objects and properties. According to Fregean representationalists such as David Chalmers and Brad Thompson, the (...) Fregean variety of the view is preferable to the Russellian variety because the former can accommodate purported counterexamples involving spectrum inversion without illusion and colour constancy while the latter cannot. I maintain that colour constancy poses a special problem for the Fregean theory in that the features of the theory that enable it handle spectrum inversion without illusion cannot be extended to handle colour constancy. I consider the two most plausible proposals regarding how the Fregean view might be developed in order to handle colour constancy—one of which has recently been defended by Thompson —and argue that neither is adequate. I conclude that Fregean representationalism is no more able to accommodate colour constancy than is Russellian representationalism and, as such, ought to be rejected. (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 lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 30, Number 1, April 2004, pp. 33-50 Constancy, Coherence, and Causality IRA M. SCHNALL According to David Hume, we believe in the existence of an external world because of the phenomena of constancy and coherence (T 1.4.2.18-43; SBN 194-210).1 Hume delineated these two aspects of our sensory experience, and claimed that they influence the imagination in such a way as to generate belief in (...) the existence of unperceived objects, independent of the mind. There is disagreement among philosophers as to the proper way to characterize constancy and coherence and the ways in which they respectively lead us to believe in external objects. The most straightforward account of coherence seems to make it the same as Hume's concept of causality. Yet Hume denies that they are the same ; and commentators disagree as to how to understand Hume's distinction between the two. As to constancy, many philosophers, following H.H. Price,2 have argued that it is really just a special case of coherence, and that its role in generating belief in external objects is the same as that of coherence. There is consequent puzzlement as to why Hume attributed a different, and more important, role to constancy. In an important recent book, Louis E. Loeb has proposed a very interesting two-part solution to this last puzzle: First, Hume is convinced that the commonsense view of the external world is patently false; so he cannot allow that it results from something as reasonable as causal inference. But the way coherence leads to belief in external objects is a form of causal inference. So, Hume wants constancy to lead to belief in external objects in a different, less reasonable way; and he wants constancy to be more important than coherence in leading to belief in the external world. Second, Hume did not realize that constancy is simply a special case of coherence (or causality), because of certain assumptions about causality that he Ira M. Schnall is at the Department of Philosophy, Bar-Ilan University, Ramat-Gan, Israel 52900. e-mail: [email protected] 34 Ira M. Schnall had inherited from his predecessors (i.e., he did not see the causality involved in the relation between an object's existing at one moment and its existing at a later moment). Therefore he appealed to non-rational mechanisms of the imagination to explain how constancy leads us to posit external objects.3 I will try to show that solutions such as Loeb's, which grant the affinity between coherence and causality and the reducibility of constancy to coherence, are unnecessary. I will propose a way to make sense of Hume's claim that coherence is not the same as causality; and I will argue that what Hume calls 'constancy' is not, and should not be, the same as, or reducible to, coherence. After introducing some basic terms, including 'constancy' and 'coherence' themselves (in section I), I will discuss the proper characterization of coherence and how it differs from causality (section II). Then I will discuss Hume's account of constancy and how it leads to belief in external obj ects; and I will contrast it with the alternative account, referred to above, that is widely held to be preferable (section III). I will argue that Hume's own account has certain advantages over the alternative (section IV) and that the main arguments against Hume's account are inconclusive (sections V and VI). The argument of section IV will yield an explanation of Hume's assigning more importance to constancy than to coherence. Finally, I will suggest (in the concluding section) that though Hume considered constancy and coherence to be merely the psychological "causes" that "induce us to believe in the existence of body," we can use them as a basis of an epistemological justification of our belief in the external world. I will make extensive use of H. H. Price's Hume's Theory of the External World; for much of the current understanding, as well as misunderstanding, of Hume's concepts of constancy and coherence is the result of the detailed analyses and arguments in that work.4 I First of...

This article attempts to do two things. The first is to make it plausible that any adequate dispositional view of color will have to associate colors with complex functions from a wide range of normal circumstances to a wide range of (simultaneously) incompatible color appearances, so that there will be no uniquely veridical appearance of any given color. The second is to show that once this move is made, dispositionalism is in a position to provide interesting answers to some of (...) the most challenging objections that have been pressed against it. It explains why colors do not seem to come on when the lights come on, and why the right thing to say seems to be that the light causes the objects to reveal their colors. It explains why the content of visual experience need not be problematically circular. It eliminates the problem of intrapersonal variation in color appearance. And it even provides resources for dealing with the problem of interpersonal variation. It is true that in moving to the more complex view, the dispositionalist becomes subject to a new objection, which has been called the problem of unity. The paper offers a solution to this problem as well. (shrink)

This article explains and defends the existence of value constancy, understood on the model of color constancy. Color constancy involves a phenomenal distinction between the transient color appearances of objects and the unchanging colors that those objects appear to have. The existence of value constancy allows advocates of response-dependent accounts of value to reject the question “What is the uniquely appropriate attitude to have toward this evaluative property?” as containing a false uniqueness assumption. Rejecting this assumption (...) allows response-dependent accounts of value to deflect or answer a host of popular objections. (shrink)

Abstract: In philosophy, perceptual constancy refers to the puzzling phenomenon of the perception of properties of objects despite our changing experience of those properties. Husserl developed a sophisticated description of perceptual constancy. In this paper I sketch Husserl's approach, which focuses on the suggestion that perception is partly constituted by the continuous interplay of intention and fulfilment. Unlike many contemporary theories, this framework gives us a way to understand the relationship between different appearances of the same object. (...) I will show how Husserl's work connects with contemporary theories which emphasize perceptual constancy from particular perspectives. These theories include appeals to perspectival properties and Cohen's counterfactual theory. Also, I show how Husserl's account shares important themes with Kelly's recent interpretation of Merleau-Ponty on perceptual constancy. (shrink)

Insofar as the vulgar belief in body arises from the ”constancy” of perceptions, it is due to the propensity to attribute identity to related objects; insofar as it arises from ”coherence,” it is produced by custom and the galley, mechanisms allied with causal inference. Since constancy is a special case of coherence, Hume could have avoided this bipartite account, subsuming constancy under custom‐and‐galley. Convinced, however, by double vision and perceptual relativity that the vulgar belief is false, Hume (...) sought to consign it to the ”imagination” in a pejorative sense. Hume was also in the grip of a thesis about causation, that only changes have causes, so that he could not contemplate a role for causal inference in cases of constancy or unchanging objects. ”Of scepticism with regard to the senses” can be amended to provide a more positive account of the belief in body, as well as a more coherent account of the propensity to ascribe identity.

The world shows some degree of invariance, and we perceive this invariance despite a lot of variation generated locally by our movements, changes in illumination, and the way in which our sense organs react to stimulation. Generally, philosophy and psychology each explain our perception of invariance through the notion of ‘perceptual constancy’. According to the traditional definition, perceptual constancies are capacities to perceive the objective (i.e., perceiver- and context-independent) local properties of external objects despite variation in the stimulation of (...) sensory organs. In this paper, we argue that the traditional understanding of perceptual constancy should be expanded to include a broader range of phenomena connected to the perception of invariance. Our argument starts from an odd activity: pole balancing. Balancing a pole-shaped object (e.g., a broomstick) on the palm of your hand in order to maintain it in an upright position requires (multimodal) perception and continuous tracking (within a certain range) of a particular kind of global invariant feature in the world. By examining this activity and its connection to the notion of perceptual constancy as it is traditionally understood, we propose an alternative account with the goal of clarifying the relationship between the alleged mechanisms underlying constancy and the philosophical implications of the phenomenon.

Sydney Shoemaker has gone to great lengths to defend a repre-sentationalist view of phenomenal character, and yet he describes this view as breaking with standard representationalism in two ways. First, he thinks his representationalist position is consis- tent with the possibility of spectrum inversion, and second, he thinks there are qualia. Thus, we can think of his position in the qualia debate as moderate representationalism (or, equally, moderate qualia realism) by taking up some middle ground be- tween these two major (...) camps. This \moderate" view faces several problems. Here I will very briey explain Shoemaker's represen- tationalist account of spectrum inversion in which he appeals to the existence of a certain sort of subjective property of objects, namely, what he calls appearance properties (formerly he called these phenomenal properties). I will argue that an alternative ver- sion of representationalism provides a more plausible explanation of both inversion-type scenarios and Shoemaker's color constancy case, which he uses to motivate the existence of these subjective properties, without positing appearance properties at all.

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)

Philosophers have long sought to explain perceptual constancy—the fact that objects appear to remain the same color, size and shape despite changes in the illumination condition, perspective and the relative distance—in terms of a mechanism that actively categorizes variable stimuli under the same pre-formed conceptual categories. Contemporary representationalists, on the other hand, explain perceptual constancy in terms of a modular mechanism that automatically discounts variation in the visual field to represent the stable properties of objects. In this paper (...) I argue that while the former view is unmotivated by empirical evidence, the later fails to account for inter- and intra-personal variability, the influence of expectations on constancy, and the systematic and normal failures of color constancy. A Bayesian approach that builds on the representational tradition in psychology solves both problems. (shrink)

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)

For a stable visual world, the colours of objects should appear the same under different lights. This property of colour constancy has been assumed to be fundamental to vision, and many experimental attempts have been made to quantify it. I contend here, however, that the usual methods of measurement are either too coarse or concentrate not on colour constancy itself, but on other, complementary aspects of scene perception.

It is proposed that the collective identification of objects is a necessary phase in the evolution of language. A procedure of identification based on the first-person perspective is assumed that is guided by object constancy, the naming insight, and other more obvious features of language production. The mental image is the basic element of this procedure. The comparison of mental images is used to define recognition, and the identification and naming of macroscopic objects by a group of persons (...) is formulated. This is shown to effect a binary relation of the order type on the set of objects that reduces to an equivalence relation in the case of observer independence. (shrink)

Sydney Shoemaker has gone to great lengths to defend a repre-sentationalist view of phenomenal character, and yet he describes this view as breaking with standard representationalism in two ways. First, he thinks his representationalist position is consis- tent with the possibility of spectrum inversion, and second, he thinks there are qualia. Thus, we can think of his position in the qualia debate as moderate representationalism by taking up some middle ground be- tween these two major camps. This \moderate" view faces (...) several problems. Here I will very briey explain Shoemaker's represen- tationalist account of spectrum inversion in which he appeals to the existence of a certain sort of subjective property of objects, namely, what he calls appearance properties. I will argue that an alternative ver- sion of representationalism provides a more plausible explanation of both inversion-type scenarios and Shoemaker's color constancy case, which he uses to motivate the existence of these subjective properties, without positing appearance properties at all.

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.

A central topic in discussions about qualia concerns their purported transparency. According to transparency theorists, an experience is transparent in the sense that the subject having the experience is aware of nothing but the intended object of the experience. In this paper this notion is criticized for failing to account for the dynamical aspects of perception. A key assumption in the paper is that perceptual content has a certain temporal depth, in the sense that each act of perception can (...) present an object as extended in time and that objects can be perceived as persisting through time. An object that is seen as persisting through time is often seen as constant and unchanging, even though the presentation of it is changing. In this paper it is argued that in order to account for these cases of perceptual constancy, we must distinguish between the awareness of having perceived that an object has a property at a certain point in time, and perceptually intending that it has that property at that point in time. Consequently, we must in at least some instances be aware of something more than the object of the experience. But precisely this distinction is rejected by the transparency theory. (shrink)

In recent discussions of two important issues in the philosophy of perception, viz. the problems of perceptual presence and perceptual constancy, Merleau-Ponty’s ideas have been garnering attention thanks to the work of Sean Kelly and Alva Noë. Although both Kelly’s normative approach and Noë’s enactive approach highlight important aspects of Merleau-Ponty’s view, I argue that neither does full justice to it because they overlook the central role that style plays in his solution to these problems. I show that a (...) closer look at the Phenomenology and several other texts from this period reveals that, on Merleau-Ponty’s account, we are able to perceive the absent features of objects as present, constant properties, and constant objects because we recognize that the objects we perceive have a unique style that persists through and unifies all their appearances.

Objects are central to perception and our interactions with the world. We perceive the world as parsed into discrete entities that instantiate particular properties, and these items capture our attention and shape how we interact with the environment. Recently there has been some debate about whether the sense of smell allows us to perceive odours as discrete objects, with some suggesting that olfaction is aspatial and doesn’t allow for object-individuation. This paper offers two empirically tractable criteria for assessing whether (...) particular objects are exhibited in perceptual experience— susceptibility to figure-ground segregation and perceptual constancies—and argues that these criteria are fulfilled by olfactory perception, and thus there are olfactory objects. I argue that there are, in fact, two different ways that olfaction allows for figure-ground segregation. First, I look at various Gestalt grouping principles, which are thought to govern when features are perceived as grouped into structured wholes, segregated from everything around them. I argue that these principles apply to olfactory experience, providing evidence of non-spatial figure-ground segregation. Second, I defend the contentious idea that a spatial variety of figure-ground segregation can also occur in olfaction. To see this, however, we need to look to empirical evidence showing that tactile stimulation and bodily movements play a crucial role in olfactory phenomenology. Finally, I draw on empirical evidence and olfactory phenomenology to argue that there are perceptual constancies in olfactory experience, allowing us to perceive odours as coherent objects that survive shifts in our perspectives on the world.

The sensory colors that figure in visual perceptual experience are either properties of the object of consciousness (naïve realism, sense-data theory), or properties of the subject of consciousness (adverbialism) (Section 1). I consider an argument suggested by the work of A. D. Smith that the existence of certain kinds of perceptual constancies shows that adverbialism is correct, for only adverbialism can account for such constancies (Section 3). I respond on behalf of the naïve realist that naïve realism is compatible (...) with the existence of such constancies, so long as naïve realism adopts the view that sensory colors are relational properties of physical objects, not intrinsic properties (Section 4). In other words, the naïve realist should adopt the theory of appearing (Section 5). (shrink)

Perceptual experience has the phenomenal character of encountering a mind-independent objective world. What we encounter in perceptual experience is not presented to us as a state of our own mind. Rather, we seem to encounter facts, objects, and properties that are independent from our mind. In short, perceptual experience has phenomenal objectivity. This paper proposes and defends a Kantian account of phenomenal objectivity that grounds it in experiences of lawlike regularities. The paper offers a novel account of the connection between (...) phenomenology and intentionality. It also sheds some light on one of the central themes in Kant’s Critique of Pure Reason. (shrink)

E.E.C. Jones’s early logical writings have recently been rescued from obscurity and it has been claimed that, in her works dating from the 1890s, she anticipated Frege’s distinction between sense and reference. This claim is challenged on the ground that it is based on a common but inadequate reading of Frege, which runs together his concept/object and sense/reference distinctions. It is admitted that a case can be made for Jones having anticipated something very like Frege’s analysis of categorical propositions, (...) and that she offered a sound rebuttal of Russell’s objection to Frege’s account of the informativeness of identity statements. However, these significant achievements should not be misrepresented as an anticipation of Frege on sense and reference, a claim that encourages a defective reading of both philosophers. (shrink)

Do the physical facts of the viewed environment account for the ordinary experiences we have of that environment? According to standard philosophical views, distal facts do account for our experiences, a phenomenon explained by appeal to perceptual constancy, the phenomenal stability of objects and environmental properties notwithstanding physical changes in proximal stimulation. This essay reviews a significant but neglected research tradition in experimental psychology according to which percepts systematically do not correspond to mind-independent distal facts. Instead, stability of percept (...) values comes in degrees, and physical facts about the viewed environment alone do not account for our ordinary experiences of the world. I conclude that more attention to descriptive research in psychophysics is warranted if what is sought is a philosophical theory of the nature of our perceptual relation with the world. (shrink)

Every perceptual experience has an objective and a subjective side. We see object size, independent of distance, but we also see that distant objects project smaller images. Early modern conceptions focused on local stimulation and thus on the subjective aspect. Helmholtz and Hering emphasized the objective aspect. Helmholtz split visual experience into two stages, with sensation representing the subjective side and perception, through cognitive processes, the objective side. Gestalt theory denied this dualism, rejecting both sensory and cognitive stages. Despite (...) contrary evidence, the sensation/perception dualism persists, in brightness models and past experience theories. That we can detect visual angle and luminance does not mean that these are raw sensations out of which perception of size and lightness is built. Size and color constancy are truly visual, not cognitive. Instructions to subjects in vision experiments must avoid the proximal mode on the one hand and cognitive judgments on the other. (shrink)

We perceive the objective world through a subjective perceptual veil. Various perceived properties, particularly “secondary qualities” like colours and tastes, are mind-dependent. Although mind-dependent, our knowledge of many facts about the perceptual veil is immediate and secure. These are well-known facets of sense-datum theory. My aim is to carve out a conception of sense-datum theory that does not require the immediate and secure knowledge of a wealth of facts about experienced sense-data (§1). Such a theory is of value on its (...) own, given well-known challenges to epistemic foundationalism. Beyond this such a theory helps demonstrate how sense-datum theory can accommodate challenging perceptual phenomena like shape and size constancies (§3). These ideas are bridged by the roots of perceptual ambiguity (§2). In brief, tapering acquaintance knowledge creates space for perceptual representation to resolve the ambiguities in presented objects seemingly inherent in scenarios involving perceptual constancies. Thus, I offer a two-factor (acquaintance-representation) sense-datum theory to meet the challenge posed by constancies. Following Smith (2002), from whom this challenge is drawn, my focus is on shape and size constancies. Other constancies, notably colour constancy, are treated elsewhere (Brown 2014). (shrink)
