Perceptual Qualities, Misc

In philosophical discussions of the secondary qualities, color has taken center stage. Smells, tastes, sounds, and feels have been treated, by and large, as mere accessories to colors. We are, as it is said, visual creatures. This, at least, has been the working assumption in the philosophy of perception and in those metaphysical discussions about the nature of the secondary qualities. The result has been a scarcity of work on the “other” secondary qualities. In this paper, I take smells and (...) place them front and center. I ask: What are smells? For many philosophers, the view that colors can be explained in purely physicalistic terms has seemed very appealing. In the case of smells, this kind of nonrelational view has seemed much less appealing. Philosophers have been drawn to versions of relationalism—the view that the nature of smells must be explained (at least in part) in terms of the effects they have on perceivers. In this paper, I consider a contemporary argument for this view. I argue that nonrelationalist views of smell have little to fear from this argument. (shrink)

Mandik (2012)understands color-consciousness conceptualism to be the view that one deploys in a conscious qualitative state concepts for every color consciously discriminated by that state. Some argue that the experimental evidence that we can consciously discriminate barely distinct hues that are presented together but cannot do so when those hues are presented in short succession suggests that we can consciously discriminate colors that we do not conceptualize. Mandik maintains, however, that this evidence is consistent with our deploying a variety of (...) nondemonstrative concepts for those colors and so does not pose a threat to conceptualism. But even if Mandik has shown that we deploy such concepts in these experimental conditions, there are cases of conscious states that discriminate colors but do not involve concepts of those colors. Mandik’s arguments sustain only a theory in the vicinity of conceptualism: The view that we possess concepts for every color we can discriminate consciously, but need not deploy those concepts in every conscious act of color discrimination.

ABSTRACT: Quassim Cassam (1997) accepts the standard account of solidity, according to which, if S feels x as solid, then S feels x as an imediment to his movement. Recently, Martin Fricke and Paul Snowdon (2003) have presented a battery of counter-examples designed to show that S may feel x as solid and as exerting a pressure that supports or facilitates his movement. In this note, I defend the standard account against Fricke and Snowdon’s attack. Integral to this defense is (...) a distinction between two (sometimes overlapping) ways in which S may feel x as an impediment to his movement: as an influence on a movement state of S, or as an obstacle to the achievement of a goal that requires movement. After demonstrating the primacy of the former sense, I argue that Fricke and Snowdon’s counter-examples only undermine a version of the standard account that glosses ‘impediment’ as an obstacle to the achievement of a goal that requires movement.

SummaryQuine uses the notion of ‘quality space’ in Word and Object and in ‘Natural Kinds' as a means of characterizing similarity recognition, which in turn is seen as basic to induction and to language acquisition. In this paper it is argued that ‘quality space’ is too simplistic a notion to bear the explanatory weight given to ‘similarity’. Similarity is explanatorily plausible only because it contains much covert complexity and is essentially mentalistic. The attempt to expunge this mentalism by the behavioural (...) mapping of quality spaces simply loses the explanatory force of similarity.RésuméQuine utilise dans ≤Word and Object≥ et dans ≤Natural Kinds≥ la notion ?on; ≤espace des qualityés≥ comme une façon de caractériser la reconnaissance de la similitude, qui est à son tour considérée comme fondamentale pour ľinduction ct pour ľacquisition du langage. auteur montre que la notion ?on; ≤cspace des qualityés≥ est trop simpliste pour fournir une base suffisante à la valeur explicative attendue de la ≤similitude≥. La similitude ňest plausible comme explication que parce qu'elle cache une grande complexité et čest une notion essentiellement mentale. La tentative de remplacer ce mentalisme par une projection behavioriste sur ľespace des qualites fait perdre à la similitude sa valeur explicative.ZusammenfassungIn ≤Word and Object≥ und in ≤Natural Kinds≥ benutzt Quine den Begriff ≤Eigenschafts‐raum≥ als Mittel um die Wahrnehmung der Ähnlichkeit zu charakterisieren, welche ihrerseits als grundlegend für Induktion und Aneignung der Sprache betrachtet wird. In der vorliegenden Arbeit wird argumentiert, dass dieser ≤Eigenschaftsraum≥ zu arm ist, um den Erklärungsgehalt des Begriffs ≤Ähnlichkeit≥ zu tragen. Die Erklärung durch Ähnlichkeit ist nur deshalb plausibel, weil sie versteckte Komplexität enthält und wesentlich mentalistisch ist. Bei dem Versuch, diesem Men‐talismus mithilfe der behavioristischen Abbildung der Eigenschäftsraume auszuweichen, geht die Erklärungskraft des Begriffs der Ähnlichkeit einfach verloren. (shrink)

Brown highlights cases of “chromatic layering”—scenarios in which one perceives an opaque object through a transparent volume/film/filter with a chromatic or achromatic content of its own—as a way of reining in the argument from perceptual variation sometimes used to motivate a relationalist account of color properties. Brown urges that the argument in question does not generalize smoothly to all types of perceptual variation—in particular, that it fits poorly in layering cases in which there is either experiential fusion or scission. While (...) he doesn’t want to reject the relationalist description of variation in all cases, he does suggest that there is an alternative, and preferable, description available for layering cases, and that the availability of this alternative puts limits on the scope of both relationalist arguments and relationalist conclusions. I claim that the obstacles for the argument from perceptual variation posed by cases of layering are merely apparent. I argue that relationalism can be extended smoothly to cases of layering, and indeed that denying this extension, as Brown proposes, contravenes ordinary and more or less universally accepted canons of rational inquiry.

This report highlights and explores five questions that arose from the Network for Sensory Research workshop on perceptual learning and perceptual recognition at the University of York on March 19th and 20th, 2012: 1. What is perceptual learning? 2. Can perceptual experience be modified by reason? 3. How does perceptual learning alter perceptual phenomenology? 4. How does perceptual learning alter the contents of perception? 5. How is perceptual learning coordinated with action?

Planar geometry was exploited for the computation of symmetric visual curves in the image plane, with consistent variations in local parameters such as sagitta, chordlength, and the curves’ height-to-width ratio, an indicator of the visual area covered by the curve, also called aspect ratio. Image representations of single curves (no local image context) were presented to human observers to measure their visual sensation of curvature magnitude elicited by a given curve. Nonlinear regression analysis was performed on both the individual and (...) the average data using two types of model: (1) a power function where. (shrink)

Intentionalism is the view that the phenomenal character of an experience is wholly determined by its representational content is very attractive. Unfortunately, it is in conflict with some quite robust intuitions about the possibility of phenomenal spectrum inversion without misrepresentation. Faced with such a problem, there are the usual three options: reject intentionalism, discount the intuitions and deny that spectrum inversion without misrepresentation is possible, or find a way to reconcile the two by dissolving the apparent conflict. Sydney Shoemaker's (1994) (...) introduction of appearance properties is a particularly ingenious way of pursuing the third strategy, by maintaining that there is a representational difference between the phenomenally spectrum-inverted subjects.2 In introducing appearance properties, Shoemaker does two things: he identifies a theoretical role for some family of properties to play, and he suggests a family of properties as candidates to play that role. I'll argue that his proposed candidates do not play the role as well as we would like, suggest some new candidates, and argue that they do a better job. (shrink)

Being in a mood—such as an anxious, irritable, depressed, tranquil, or cheerful mood—tends to alter the way we react emotionally to the particular objects we encounter. But how, exactly, do moods alter the way we experience particular objects? Perceptualism, a popular approach to understanding affective experiences, holds that moods function like "colored lenses," altering the way we perceive the evaluative properties of the objects we encounter. In this essay, I offer a phenomenological analysis of the experience of being in a (...) mood that illustrates the limitations of the colored lens metaphor and demonstrates the basic inadequacy of the perceptualist account of moods. I argue that when we are in a mood, it is common to experience a kind of "emotional disconnection" in which we perceive evaluative properties that would normally elicit strong emotional reactions from us, but nonetheless we find that, in our present mood, we remain emotionally numb to these perceptions. Such experiences of "seeing but not feeling" are difficult to understand from within the perceptualist paradigm. Building on the work of Martin Heidegger, I sketch an alternative, phenomenological analysis of moods that can better account for experiences of emotional disconnection. On this alternative account, being in a mood does not merely alter the content of our perceptions but, rather, alters the way we interpret the overall significance of what we perceive, relative to a certain situational context.

Studies show that there are widespread intrasubjective and intersubjective color variations among normal perceivers. These variations have serious ramifications in the debate about the nature and ontology of color. It is typical to think of the debate about color as a dispute between objectivists and subjectivists. Objectivists hold that colors are perceiver-independent physical properties of objects while subjectivists hold that they are either projections onto external objects or dispositions objects have to look colored. I argue that individual color variations present (...) difficulties, albeit not the same kind, for both objectivism and subjectivism. Lastly, I propose an alternative account that handles such variations nicely. (shrink)

In my dissertation I critically survey existing theories of time consciousness, and draw on recent work in neuroscience and philosophy to develop an original theory. My view depends on a novel account of temporal perception based on the notion of temporal qualities, which are mental properties that are instantiated whenever we detect change in the environment. When we become aware of these temporal qualities in an appropriate way, our conscious experience will feature the distinct temporal phenomenology that is associated with (...) the passing of time. The temporal qualities model of perception makes two predictions about the mechanisms of time perception; one that time perception is modality specific and the other that it can occur without awareness. My argument for this view partially depends on a number of psychophysical experiments that I designed and implemented myself and which investigate subjective time distortions caused by looming visual stimuli. These results show that the mechanisms of conscious experience of time are distinct from the mechanisms of time perception, as my theory of temporal qualities predicts. (shrink)

In Consciousness Revisited: Materialism without Phenomenal Concepts 2009, Cambridge, MA: MIT Press, Michael Tye claims that seeing can occur independently of seeing-that. Call this The Independence Claim (TIC). Tye supports this ‘general point’ by appeal to cases of ‘ubiquitous error’ (2009: 95). In this article, I show that this strategy fails: it is guilty of a certain blindness to how things look.

Representational theories of mind cannot individuate the sense modalities in a principled manner. According to representationalism, the phenomenal character of experiences is determined by their contents. The usual objection is that inverted qualia are possible, so the phenomenal character of experiences may vary independently of their contents. But the objection is inconclusive. It raises difficult questions about the metaphysics of secondary qualities and it is difficult to see whether or not inverted qualia are possible. This paper proposes an alternative test (...) of representationalism. Do experiences in different sense modalities have the same phenomenal character when they share content? Psychological work on the perception of shape through vision and spatial hearing is discussed. This work shows that visual and auditory experiences differ in phenomenal character even in so far as they represent similar properties. This objection to representationalism does not invite questions about secondary qualities or depend on establishing metaphysical possibilities. (shrink)

The chapter outlines an abstract theoretical framework that is currently (re-)emerging in the course of a theoretical convergence of several disciplines. In the first section, the fundamental problem of perception theory is formulated, namely, the generation, by the perceptual system, of meaningful categories from physicogeometric energy patterns. In the second section, it deals with basic intuitions and assumptions underlying what can be regarded as the current Standard Model of Perceptual Psychology and points out why this model is profoundly inadequate for (...) dealing with the fundamental problem of perception theory. In the third section, it discusses a level of analysis that promises to be fruitful for dealing, in conformity with established procedures of the natural sciences, with the problem of perceptual “meaning” and the problem of what constitutes a “perceptual object.” In the fourth section, it outlines a theoretical perspective on basic principles of the perceptual system which centers on the notions of complex data types and conceptual forms, and draws an entirely different theoretical picture of the role of the sensory input than traditional accounts. The final section focusses on the issue of material qualities and discusses, within the general theoretical framework outlined, some observations and results on the perception of certain material properties, namely, lustrous and glassy appearances.

Some sounds have pitch, some do not. A tuba’s notes are lower pitched than a flute’s, but the fuzz from an untuned radio has no discernible pitch. Pitch is an attribute in virtue of which sounds that possess it can be ordered from “low” to “high”. Given how audition works, physics has taught us that frequency determines what pitch a sound auditorily appears to have.

In this paper, I address the issue of the ontological status of qualitative properties. I discuss the prevalent approaches to the problem of qualia in philosophy of mind, in relation to the various attempts at naturalizing the mind and the various theories of perception. I compare these views with Husserl's phenomenology, highlighting the phenomenological distinction between phenomenal contents of mental states and sensory properties of the perceived objects. I present some open issues of this view, in order to show how (...) they can be addressed in the light of some developments of the phenomenological inquiry in Husserl and Merleau-Ponty. (shrink)

Do we communicate with pictures? If so, the text asks, what about their complex, dynamic appearances? Are they part of the communication process? By analysing a cover image of the journal Jugend from 1896 and by consulting the research on the logic of pictures (“Eigenlogik”) in Bildwissenschaft, Iconology and Cultural Anthropology these questions shall be persued. The analysis suggests, that instead of consenting the results of epistemological aesthetic research a new understanding of pictures shall be implemented: They can be considered (...) as parts of cultural semiotic processes. That means, it is not the view of something (epistemology) but the view of someone (culture) that is shown by the pictures. - I - -/- Kommunizieren wir über Bilder? Falls das zutrifft, stellt sich die Frage, ob daran auch deren komplexe dynamische Erscheinungsweise Anteil hat? Über die Analyse eines Titelblatts der Zeitschrift Jugend von 1896 und die Betrachtung der Forschungen zur Eigenlogik von Bildern in Bildwissenschaft, Ikonologie und Kultureller Anthropologie soll diesen Fragen nachgegangen werden. Die Auswertung veranlasst, sich von der klassischen, erkenntnisorientierten, ästhetischen Theorie zu distanzieren und sie als kulturtheoretische, semiotische Theorie neu zu fassen. Die Neuausrichtung wird im Verständnis des Gehalts der Bilder im medialen Transfer greifbar: Statt in einer Ansicht von etwas (Erkenntniswert), so eröffnet sich, liegt er in einer Ansicht über etwas (Meinung/Kulturwert).

This paper distinguishes two types of qualia theory, which I call Galilean and non-Galilean qualia theories. It also offers considerations against each type of theory. To my mind the considerations are powerful. In any case, they bring out the importance of distinguishing the two types of theory. For they show that different considerations come into play—or considerations come into play in quite different ways—in assessing the two types of theory.

This paper articulates a case for supposing that all shades of colour are visually complex.

Taken at face value, the picture of reality suggested by modern science seems radically opposed to the world as we perceive it through our senses. Indeed, it is not uncommon to hear scientists and others claim that much of our perceptual experience is a kind of pervasive illusion rather than a faithful presentation of various aspects of reality. On this view, familiar properties such as colours and solidity, to take just two examples, do not belong to external objects, but are (...) fictions generated by the brain that we mistakenly ascribe to the world around us. Contrary to this view, I argue that properties like colour and solidity are as much a part of the fabric of reality as gravity and electrons, and that our scientific and common-sense world views are not as opposed to one another as it might first appear.
