David J. Bennett The Role of Spatial Appearances in Achieving Spatial-Geometric Perceptual Constancy
abstract | view |  rights & permissions | cited by
Long tradition in philosophy and in empirical psychology has it that the perceptual recovery of enduring objective size and shape proceeds through initial spatial appearance experiences—like the sensed changing visual field size of a receding car, or the shifting shape appearance of a coin as it rotates in depth. The present paper carefully frames and then critically examines such proposals. It turns out that these are contingent, empirical matters, requiring close examination of relevant research in perception science in order to decide. The paper concludes with extended discussions of the empirical study of the perception of slant, size, and shape.

Robert Briscoe Depiction, Pictorial Experience, and Vision Science
abstract | view |  rights & permissions | cited by
Pictures are patterned, 2D surfaces designed to elicit 3D-scene-representing experiences from their viewers. In this essay, I argue that philosophers have tended to underestimate the relevance of research in vision science to understanding the nature of pictorial experience. Both the deeply entrenched methodology of virtual psychophysics as well as empirical studies of pictorial space perception provide compelling support for the view that pictorial experience and seeing face-to-face are experiences of the same psychological, explanatory kind. I also show that an empirically informed account of pictorial experience provides resources to develop a novel, resemblance-based account of depiction. According to what I call the deep resemblance theory, pictures work by presenting virtual models of objects and scenes in phenomenally 3D, pictorial space.

Berit Brogaard Perceptual Appearances of Personality
abstract | view |  rights & permissions | cited by
Perceptual appearances of personality can be highly inaccurate, for example, when they rely on race, masculinity, and attractiveness, factors that have little to do with personality, as well as when they are the result of perceiver effects, such as an idiosyncratic tendency to view others negatively. This raises the question of whether these types of appearances can provide immediate justification for our judgments about personality. I argue that there are three reasons that we should think that they can. (i) The inaccuracy of these types of appearances is not nearly as widespread as it may initially seem. Even thin-slicing in zero-acquaintance conditions seems to reliably track many personality traits. (ii) The thought that perceptual appearances of personality can justify our beliefs only in conjunction with background information rests on a failure to acknowledge the existence of genuine high-level perceptual appearances of personality. (iii) Perceiver effect cases are not unlike cases in which we have inaccurate low-level perceptual appearances in unfavorable perceptual conditions.

John Campbell The Problem of Spatiality for a Relational View of Experience
abstract | view |  rights & permissions | cited by
It’s often said that relational view of experience can’t provide an explanation of mode of presentation phenomena: the idea is that if experience is characterized merely as a relation to an object, then we can’t make sense of the idea that one and the same object can be given in perception in many different ways. I show that we can address this problem by looking at the causal structure in relational experience. Experience of an object is caused by experience of particular properties it has, such as its color and location, and experience of the object is in turn a cause of experience of its properties as characteristics of that object. We can explain mode of presentation phenomena as a matter of there being different sets of properties that can cause perception of one and the same object. I discuss how experiments in vision science and computational models of vision can underwrite this way of finding the causal structure in experience, relationally conceived. I look at an alternative, internalist approach to mode of presentation phenomena, in terms of ‘mental paint’, and suggest that the internalist approach is simply incoherent. Finally, I point out that we have mode of presentation phenomena for the spatial aspects of vision, such as perception of spatial relations and spatial location, but that these phenomena resist analysis in any of the terms proposed so far.On a relational view, visual experience is a relation between the perceiver and the scene observed. It’s often said, quite wrongly, that relational views of experience cannot reckon with mode-of-presentation phenomena. I begin by explaining how a relational view of experience can make sense of the idea of the ‘way’ in which an object is given to the perceiver, in terms of the properties used to single out the object. I explain why relational views are to be preferred to approaches in terms of ‘mental paint’. I then sketch the problem posed by spatial perception. Spatial perception is peculiarly difficult to characterize on a relational view, because it’s difficult to characterize the way in which spatial locations and layouts are given to the subject.

E. J. Green Representationalism and Perceptual Organization
abstract | view |  rights & permissions | cited by
Some philosophers have suggested that certain shifts in perceptual organization are counterexamples to representationalism about phenomenal character. Representationalism about phenomenal character is, roughly, the view that there can be no difference in the phenomenal character of experience without a difference in the representational content of experience. In this paper, I examine three of these alleged counterexamples: the dot array (Peacocke 1983), the intersecting lines (Speaks 2010), and the 3 X 3 grid (Nickel 2007). I identify the two features of their phenomenology that call for explanation: grouping and prominence. I then argue that representationalists can adequately account for both of these features. I also critique some previous treatments of grouping and prominence.

Gary Hatfield Perceiving as Having Subjectively Conditioned Appearances
abstract | view |  rights & permissions | cited by
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.

Christopher S. Hill Perceptual Relativity
abstract | view |  rights & permissions | cited by
Visual experience is shaped by a number of factors that are independent of the external objects that we perceive—factors like lighting, angle of view, and the sensitivities of photoreceptors in the retina. This paper seeks to catalog, analyze, and explain the fluctuations in visual phenomenology that are due to such factors.

Geoffrey Lee Does Experience Have Phenomenal Properties?
abstract | view |  rights & permissions | cited by
What assumptions are built into the claim that experience has “phenomenal properties,” and could these assumptions turn out to be false? I consider the issue specifically for the similarity relations between experiences: for example, experiences of different shades of red are more similar to each other than an experience of red and an experience of green. It is commonly thought that we have a special kind of epistemic access to experience that is more secure than our access to the external environment. In the first part of the paper, I argue than one way of elucidating this claim is especially plausible—that systematic error, of the kind subjects make about the external environment in traditional “skeptical” scenarios, is not conceivable for introspection of experience, including for our knowledge of similarity relations. I argue that focusing on similarity relations gives us a more interesting version of the argument than for other forms of experiential introspection. Then in the second part of the paper I describe an example, inspired by a similar case due to Sydney Shoemaker, in which a subject, despite being fully rational and attentive, apparently is systematically mistaken about the character of their experience in a surprising way. I argue that the example calls into question whether there are properties of experience satisfying the epistemic access constraint, and therefore whether experience has “phenomenal properties” in the intuitive sense.

Jessie Munton Visual Confidences and Direct Perceptual Justification
abstract | view |  rights & permissions | cited by
What kind of content must visual states have if they are to offer direct (noninferential) justification for our external world beliefs? How must they present that content if the degree of justification they provide is to reflect the nuance of our changing visual experiences? This paper offers an argument for the view that visual states comprise not only a content, but a confidence relation to that content. This confidence relation lets us explain how visual states can offer noninferential perceptual justification of differing degrees for external world beliefs. These confidence relations let visual states justify beliefs in a way that is sensitive to subtle differences in the character of our visual experiences, while still allowing that visual states give us direct access to the external world in virtue of their content.
