One of the central assumptions made in much of contemporary philosophy of mind is that there is no appearance-reality distinction when it comes to sensory states. On this assumption, sensory states simply are as they seem: consciousness is an intrinsic property of sensory states—that is, all sensory states are conscious—and the consciousness of one’s own sensory states is never inaccurate. For a sensation to be felt as pain, for example, is (...) for it to be pain. This assumption, which I call the Cartesian assumption, can be seen everywhere from the standard arguments against physicalism—such as those advanced by Kripke, Nagel, and Levine—to current theorizing about consciousness. I here argue that this assumption is false and that it goes wrong in two ways. I further argue that the appeal of the Cartesian assumption is due to a commitment many still have to a poorly motivated and misguided Cartesian model of consciousness and its relation to mental states. As an alternative to this Cartesian concept of mind, I argue for a theory of consciousness which claims that the “phenomenal character” of a sensation or perception—the “what it’s like” to have that sensation—is determined by the content of a higher-order thought one has of that sensory state.

La autora presenta una critica a la concepcion clasica de los sentidos asumida por la mayoria de autores naturalistas que pretenden explicar el contenido mental. Esta crítica se basa en datos neurobiologicos sobre los sentidos que apuntan a que estos no parecen describir caracteristicas objetivas del mundo, sino que actuan de forma ʼnarcisita', es decir, representan informacion en funcion de los intereses concretos del organismo.El articulo se encuentra también en: Bechtel, et al., Philosophy and the Neuroscience.

This is a chapter from my book Perception (Routledge). I explain the physical state view of sensory experience (Papineau, McLaughlin, others). I criticize an argument against it based on the "transparency observation". Then I develop two alternative arguments against it. The first is a Leibniz's Law argument based on the essentially externally directed character of some experiences. The second concerns "brains in vats". Finally I consider a recent response due to David Papineau, which involves rejecting essential external directedness.

The concept of an altered state of consciousness may be clarified when three major issues are discussed: the phenomenon, its method of induction, and criteria for evaluating the phenomenon. An ASC is a mental state, but it is not clear how such a mental state is related to subjective experience and cognitive functioning. The relationship between the method of induction and the resulting ASC is also unclear at present. Finally, criteria for determining and evaluating the ASC are indistinguishable from the (...) phenomenon itself, leaving the latter ill-defined. These are the basic issues which are addressed in the theoretical formulation here presented. I propose that the cognitive mode distinguishing the normal waking state from an ASC is the mode of meaning employed. (shrink)

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main (...) contenders, critically compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

Consciousness alterations can be experienced during unstructured, monotonous stimuli. These effects have not been linked to particular cognitive operations; individual differences in response to such stimulation remain poorly understood. We examined the role of hypnotizability and dissociative tendencies in mind-wandering during a sensory homogenization procedure . We expected that the influence of ganzfeld on MW would be more pronounced among highly hypnotizable individuals , particularly those high in dissociative tendencies. High and low hypnotizables, also stratified by dissociation, completed the (...) sustained attention to response task during ganzfeld and control conditions. High dissociative highs made more commission errors during ganzfeld, suggesting increased MW, whereas the other groups displayed the opposite pattern. Increases in commission errors from the control condition to ganzfeld were associated with more alterations in consciousness and negative affect, but only among highs. Sensory homogenization had opposite effects on MW depending on the interaction of hypnotizability and dissociation. (shrink)

David Papineau’s _The Metaphysics of Sensory Experience_ is deep, insightful, refreshingly brisk, and very readable. In it, Papineau argues that sensory experiences are intrinsic and non-relational states of subjects; that they do not essentially involve relations to worldly facts, properties, or other items (though they do happen to correlate with worldly items); and that they do not have truth conditions simply in virtue of their conscious (i.e., phenomenal) features. I am in enthusiastic agreement with the picture as (...) described so far. But Papineau also argues that sensory experiences are in no interesting sense essentially representational and that what is responsible for their truth conditions is their correlations with the environment. Here, I disagree. Indeed, I think Papineau does not follow his arguments to their proper conclusions. For if sensory experiences are intrinsic, non-relational, and only contingently correlated with worldly conditions (as Papineau and I agree they are), then the phenomenal features of sensory states are representational in an important sense: they constitute what we think, perceptually experience, or otherwise entertain, making up how things seem to us from a first-person perspective. Because of this, the truth conditions of perceptual experiences cannot be entirely independent of their phenomenal features. They cannot merely be a matter of environmental correlations. If we follow Papineau’s arguments to their proper conclusions, we end up with a view much closer to a version of representationalism that Papineau dismisses, a view he calls “pure phenomenal intentionalism”.

Sensory Individuals: Unimodal and Multimodal Perspectives provides an interdisciplinary, well-balanced, and comprehensive look at different aspects of unisensory and multisensory objects, using both nuanced philosophical analysis and informed empirical work. The research presented in this book represents the field's progression from treating neural sensory processes as primarily modality-specific towards its current state of the art, according to which perception, and its supporting neural processes, are multi-modal, modality-independent, meta-modal, and task-dependent. Even within such approaches sensory stimuli, properties, brain (...) activations, and corresponding perceptual phenomenology can still be characterized in a modality-specific way. The book examines the basic building blocks of human perception, and whether they are best understood as sense modality dependent units of different forms or multimodal perceptual objects. The book combines a variety of innovative and integrative angles to explore the topic and acts as a catalyst for an increasingly diverse field of research, which is in an exciting phase of growth and advancement. New questions are arising as quickly as they are being answered, and the collection Sensory Individuals provides an original and up-to-date addition to the field. (shrink)

It is typically assumed that while we know other people’s mental states by observing and interpreting their behavior, we know our own mental states by introspection, i.e., without interpreting ourselves. In his latest book, The opacity of mind: An integrative theory of self-knowledge, Peter Carruthers (2011) argues against this assumption. He holds that findings from across the cognitive sciences strongly suggest that self-knowledge of conscious propositional attitudes such as intentions, judgments, and decisions involves a swift and unconscious process (...) of self-interpretation that utilizes the same sensory channels that we employ when working out other people’s mental states. I provide an overview of Carruthers’ book before discussing a pathological case that challenges his account of self-knowledge and mentioning empirical evidence that undermines his use of a particular kind of data in his case against introspection of conscious attitudes.

In ‘Of Sensory Systems and the “Aboutness” of Mental States’, Kathleen Akins (1996) argues against what she calls ‘the traditional view’ about sensory systems, according to which they are detectors of features in the environment outside the organism. As an antidote, she considers the case of thermoreception, a system whose sensors send signals about how things stand with themselves and their immediate dermal surround (a ‘narcissistic’ sensory system); and she closes by suggesting that the signals from (...) many sensory systems may not in any familiar sense be about anything at all. Her presentation of the issues, however, overlooks resources available to ‘the traditional view’—or so I shall argue. Akins’s own thumbnail sketch of what is wrong with the traditional view is that it asks, concerning a given sensory system, ‘what is it detecting?’, when we should instead be asking ‘what is it doing?’ (352). Her point is that on the traditional view the function of a sensory system—what it's ‘for’—is to detect or indicate (values of) features of the outside environment. But at least on one version of the traditional view—namely Ruth Millikan’s—this would never be the sole or main proper function of a sensory system. (Akins does not list Millikan as a traditionalist, but Millikan fits squarely Akins’s description of them, since she believes in a naturalistic theory of aboutness and thinks it should begin with the senses.) For Millikan (1989, 1993), the proper function of a sensory system is in the first instance enabling behavioural systems—in the simplest case, motor routines—to perform their proper function. This they do, roughly, by switching on and steering the behavioural routines. Where features of the outside environment come in is as Normal (= assumed-by-the-design) conditions for the successful performance of the sensory system's proper function. That is, the only strategy for switching on and steering that is simple enough for evolution to have hit upon it, and reliable enough for evolution to have liked it, is a strategy which gears the steering to (values of) features of the outside environment. But as soon as one starts fleshing out the details of this story, one notices that they are probably quite different in the case of thermoreception from how they are with ‘distance’ senses such as vision and olfaction--a point which Akins overlooks..

Philosophers and cognitive scientists address the relationships among the senses and the connections between conscious experiences that form unified wholes. In this volume, cognitive scientists and philosophers examine two closely related aspects of mind and mental functioning: the relationships among the various senses and the links that connect different conscious experiences to form unified wholes. The contributors address a range of questions concerning how information from one sense influences the processing of information from the other senses and how unified (...) class='Hi'>states of consciousness emerge from the bonds that tie conscious experiences together. Sensory Integration and the Unity of Consciousness is the first book to address both of these topics, integrating scientific and philosophical concerns. A flood of recent work in both philosophy and perception science has challenged traditional conceptions of the sensory systems as operating in isolation. Contributors to the volume consider the ways in which perceptual contact with the world is or may be “multisensory,” discussing such subjects as the modeling of multisensory integration and philosophical aspects of sensory modalities. Recent years have seen a similar surge of interest in unity of consciousness. Contributors explore a range of questions on this topic, including the nature of that unity, the degree to which conscious experiences are unified, and the relationship between unified consciousness and the self.

This is an excerpt from a report on the Sensory Substitution and Augmentation Conference at the British Academy in March of 2013. This portion of the report explores the question: Does sensory substitution generate perceptual or cognitive states?

Many sensory states motivate. I offer an account of how such states compel intentional action. I focus on thirst as it is relatively simple in physiological and behavioral terms, it carries little theoretical baggage, and the motivational story for thirst seems likely to generalize. I argue that thirst motivates using a variety of flexible strategies, and that no single explanatory mechanism fully captures its motivational force. The resulting view, the aggregation model of sensory motivation, offers the (...) most plausible account of how sensory states motivate. (shrink)

Postural instability in Parkinson’s disease (PD) is characterized by impaired postural responses to transient perturbations, increased postural sway in stance and difficulty transitioning between tasks. In addition, some studies suggest that loss of dopamine in the basal ganglia due to PD results in difficulty using proprioceptive information for motor control. Here, we quantify the ability of subjects with PD and age-matched control subjects to use and re-weight sensory information for postural control during steady-state conditions of continuous rotations of the (...) stance surface or visual surround. We measure the postural sway of subjects in response to a pseudorandom, surface-tilt stimulus with eyes closed, and in response to a pseudorandom, visual-tilt stimulus. We use a feedback control model of the postural control system to interpret our results, focusing on sensory weighting as a function of stimulus amplitude. We find that subjects with PD can re-weight their dependence upon sensory information in response to changes in surface- or visual-stimulus amplitude. Specifically, subjects with PD behaved like age-matched control subjects by decreasing proprioceptive contribution to stance control with increasing surface-tilt amplitude, and decreasing visual contribution with increasing visual-tilt amplitude. However, subjects with PD do not decrease their reliance on proprioception as much as age-matched controls for small increases in surface-stimulus amplitudes. Levodopa medication did not affect sensory re-weighting behaviors for postural control. The impairment in PD subject’s ability to respond differently to small changes in surface rotation amplitudes is consistent with an increased threshold for perceiving proprioceptive signals, which may result from decreased signal-to-noise in the dopaminergic pathways associated with sensory processing and/or sensory integration.

Despite considerable growth in understanding of various aspects of sporting and exercise embodiment over the last decade, in-depth investigations of embodied affectual experiences in running remain limited. Furthermore, within the corpus of literature investigating pleasure and the hedonic dimension in running, much of this research has focused on experiences of pleasure in relation to performance and achievement, or on specific affective states, such as enjoyment, derived after completing a run. We directly address this gap in the qualitative literature on (...) sporting and exercise embodiment by contributing novel insights on the mind-body pleasures of running via focusing analytic attention towards the pleasures recalled by runners as experienced during positive, rewarding running experiences. Applying conceptual insights drawn from sociological phenomenology, we analyse data from an in-depth, event-focused interview study with distance runners who reported positive, rewarding experiences in recent recreational runs. Through reflexive thematic analysis, we present findings in relation to three themes: (1) ‘running feels like it should’; (2) sensory engagements; and (3) time out. The study contributes fresh perspectives, both conceptually and in relation to data-collection approach, to a small literature on the lived experience of pleasure in sport, exercise and physical cultures.

The capacity for feature binding is typically explained in terms of the attribution model: a perceptual state selects an individual and attributes properties to it (Kahneman & Treisman 1984; Clark 2004; Burge 2010). Thus features are bound together in virtue of being attributed to the same individual. While the attribution model successfully explains some cases of binding in perception, not all binding need be understood as property attribution. This chapter argues that some forms of binding—those involving holistic iconic representations, which (...) bind features outside the limits of attention and object files—don’t fit the attribution model. The chapter then sketches an alternative coordination model of binding that construes icons as complex analog representations. (shrink)

The phenomenal character of conscious experience has long been regarded as the major problem for physicalist accounts of consciousness. In recent years, defenders of physicalism have typically been relying on the so-called Phenomenal Concept Strategy to avoid dualism. In this paper, we argue with PCS that cognitive-physicalistic explanations can account for the peculiarities of phenomenal character. However, we think that the conceptual features PCS investigates are not the genuine causes of the special characteristics of phenomenal consciousness but only symptoms, which (...) can themselves be explained in terms of the features of the sensory-perceptual representations underlying conscious experiences, namely that some, but not all, of these states are representationally unstructured.

In recent years, cognitive neuroscientists have began to explore the process of how sensory information gains access to awareness. To further probe this process, event-related functional magnetic resonance imaging was used while testing subjects with a paradigm known as the “attentional blink.” In this paradigm, visually presented information sporadically fails to reach awareness. It was found that the magnitude and time course of activation within the anterior cingulate , medial prefrontal cortex , and frontopolar cortex predicted whether or not (...) information was consciously perceived during the critical period for the attentional blink. These results are discussed in light of a neural framework for conscious processing. (shrink)

What is going on when we are consciously aware of a visual scene, or hear sounds, or otherwise enjoy sensory experience? David Papineau argues controversially for a purely qualitative account: conscious sensory experiences are intrinsic states with no essential connection to external circumstances or represented properties.

[Late draft.] The paper examines the roles that may be played by sensory images in relation to the contents of sensory memories. It argues that the images may serve either simply to characterise putative past states of the world or to capture putative past sensory experiences of the subject. It uses the resulting account to shed light on various phenomena involving sensory memories, such as the status of 'observer memories'.

I can be wrong about things I seem to perceive; the conditions might lead me to be mistaken about them. Since I can't rule out the possibility that the conditions are misleading, I can't be sure that I am perceiving this thing in my hand correctly. But suppose that I am able to examine it actively—handling it, looking closer, shining a light on it, and so on. Then, my level of uncertainty goes down; in the limit it is eliminated entirely. (...) Of course, I might be mistaken because I am a brain in a vat, or because some other sceptical scenario obtains. But sceptical scenarios apply not just to this thing in my hand, but to everything all at once. Define "empirical certainty" as the absence of the kind of doubt that spreads to all empirical states of affairs. Sensory exploration, or active examination, can in principle lead to empirical certainty. (shrink)

When a mental state is conscious – in the sense that there is something it is like for the subject to have it – it instantiates a certain property F in virtue of which it is a conscious state. It is customary to suppose that F is the property of having sensory quality. The paper argues that this supposition is false. The first part of the paper discusses reasons for thinking that unconscious mental states can have a (...) class='Hi'>sensory quality, for example in cases of absent-minded perception. If unconscious mental states can have a sensory quality, then sensory quality is an insufficient condition for consciousness. The second part of the paper argues that there are even better reasons to think that sensory quality is an unnecessary condition for consciousness. The idea is that mental states can be conscious even when they lack sensory quality, for example, in the case of certain conscious propositional attitudes. In the third part of the paper, an alternative to the rejected supposition, drawn from the phenomenological tradition, is offered: that consciousness is a matter of implicit self-awareness, rather than of sensory quality. According to this alternative, a mental state is conscious when, and only when, it involves implicit self-awareness. (shrink)

1. Clark’s book is a detailed study of the nature of sensory representation. It is highly informed by empirical results in the psychology of perception, and philosophically rich and significant. I admire the book and learned a great deal from reading it. As it covers a wide range of topics, and as I have no overarching critique to present, in this commentary I will briefly address three issues that come up in the book: Clark’s relational type-identity thesis for (...) class='Hi'>sensory qualities, his theory that sensory representations involve proto-singular terms referring to spatio-temporal regions in the subject’s environment, and his interesting proposal concerning color to treat it as “difference coding”. Some of my remarks will be critical, but others will just explore some of the implications of his view. 2. Clark distinguishes “phenomenal properties” from “qualitative properties”, the former being appearance properties of things in the world (their colors, shapes, tastes, odors, etc.) and the latter being the properties of sensations by virtue of which they are sensations of their corresponding phenomenal properties. So when I see a red ball I am “directly” aware of the ball’s redness and roundness - it appears red and round to me. This awareness of the ball’s redness and roundness is accomplished, however, by my having a visual experience with certain qualitative properties; those that are of the sort one has when seeing something as red and round. It is these latter qualitative properties that are the subject of his relational type-identity thesis. Before addressing that thesis, however, I want to quickly note and respond to another point Clark makes concerning the qualitative properties of sensory states. He.. (shrink)

Our emotional states affect how we perceive the world. If I am stressed, annoyed, or irritated, I might experience the sound of children laughing and screaming as they play around the house in a negative manner — it is unpleasant, loud, piercing, and so on. Yet, if I’m in a relaxed, happy, loving mood, the very same sounds might be experienced as pleasant, playful, warm, and so on. The sounds being made by the children are the same in both (...) cases, but how they are experienced differs. The auditory experience is affected by the emotional state that I am in. I perceive the sounds differently depending on how I’m feeling. Although this might at first seem to be a trivial observation, it certainly is not. We take for granted that our perceptual experiences give rise to justified beliefs and knowledge. Thus, if my perceptual experience of an object can differ based on my emotional state, and I take my perceptual experience to justify my beliefs and even lead to knowledge, then we might have a problem. If emotions — which are not fixed and in large part uncontrolled — affect our ability to accurately perceive the world, then they may undermine the justified beliefs and knowledge gained on the basis of our perceptual experience of the world. My goal here is to explore this potential problem. -/- I consider how we might understand the effect that emotions have on the justification of our perceptual beliefs about the world, beliefs that we acquire from a variety of sensory modalities — audition, gustation olfaction, and so on. I take the problem to be associated with one of two forms of perceptual influence: penetration or multisensory integration. In any given perceptual moment there are multiple sensory modalities and mental states at play, each affecting the overall experience. Whether we understand the influence of emotion on perception as a form of non-perceptual penetration or a form of non-visual sensory perception of the inner body — interoception — the potential epistemological difficulties remain: how can we be said to acquire justified beliefs and knowledge on the basis of such influenced perceptual experience. As has been the norm, only the five exteroceptive senses of vision, audition, olfaction, taste and touch are typically discussed in the context of sensory perception. However, as I argue, there is strong reason to accept the claim that emotional experience is a form of interoception, and that interoception ought to be considered when discussing sensory perception. In this way, then, I propose that clarifying the role played by interoception in sense perception across modalities is necessary if we are to make progress on the epistemological problems at hand.

In this paper, I argue that the conscious awareness one has of oneself as acting, i.e., agentive awareness, is not a type of sensory awareness. After providing some set up in Sect. 1, I move on in Sect. 2 to sketch a profile of sensory agentive experiences as representational states with sensory qualities by which we come to be aware of ourselves as performing actions. In Sect. 3, I critique two leading arguments in favor of positing (...) such sensory experiences: the argument from pathology and the argument from cognitive impenetrability. Since neither of these arguments succeeds, the case for positing SAEs is dealt a significant blow. I proceed in Sect. 4 to advance my positive argument against SAEs. The argument runs as follows: If SAEs exist, then they must exist in some sensory modality or set of sensory modalities. Either the relevant sensory modalities are ones that we already recognize, or they are novel sensory modalities. I will argue that neither of these options is workable, and so we have nowhere to locate SAEs. Agentive awareness is not sensory awareness. (shrink)

This dissertation examines representationalism about sensory phenomenology—the claim that for a sensory experience to have a particular phenomenal character is a matter of it having a particular representational content. I focus on a particular issue that is central to representationalism: whether reductive versions of the theory should be internalist or externalist. My primary goals are to demonstrate that externalist representationalism fails to provide a reductive explanation for phenomenal qualities, and to present a reductive internalist version of representationalism that (...) utilizes the empirical framework of psychophysics and neuroscience to develop a philosophical theory of content. The bulk of the project is an attempt to provide the outlines of what such an empirically-based representationalist theory would look like. In chapter 2, I argue that reductive externalist representationalism fails because it is vulnerable to the problem of bad structural correlation: the mismatch between the structure of phenomenal qualities and the structure of physical properties “tracked” by our sensory systems with which phenomenal qualities are identified. In chapter 3, I develop the outlines of a reductive internalist version of representationalism that characterizes phenomenal qualities as modes of presentation of sensory representations that can be reductively characterized in terms of a location in a psychophysically-defined quality space, which can in turn be given a neurophysiological interpretation. In addition, I argue that the neural mechanisms responsible for the representation of spatial locations and visual objects serve a referential role in sensory psychosemantics that grounds the intentionality of sensory states. In chapter 5 I provide a detailed account of the representation of spatial locations in sensory experience, and in chapter 6 I examine the “binding problem”, demonstrating how object-based sensory representations function to demonstratively pick out sensory individuals without explicitly representing any of their features. I describe the resulting view as methodological representationalism: an attempt to demonstrate how a particular philosophical theory of sensory phenomenology can be integrated into the empirical framework of cognitive science, and thereby provide an explanatory psychosemantic framework for sensory phenomenology that is valuable to both philosophers and cognitive scientists.

A key question in studying consciousness is how neural operations in the brain can identify streams of sensory input as belonging to distinct modalities, which contributes to the representation of qualitatively different experiences. The basis for identification of modalities is proposed to be constituted by self-organized comparative operations across a network of unimodal and multimodal sensory areas. However, such network interactions alone cannot answer the question how sensory feature detectors collectively account for an integrated, yet phenomenally differentiated (...) experiential content. This problem turns out to be different from, although related to, the binding problem. It is proposed that the neural correlate of an enriched, multimodal experience is constituted by the attractor state of a dynamic associative network. Within this network, unimodal and multimodal sensory maps continuously interact to influence each other’s attractor state, so that a feature change in one modality results in a fast re-coding of feature information in another modality. In this scheme, feature detection is coded by firing-rate, whereas firing phase codes relational aspects. (shrink)

It has been known for over a century that there is an afferent, as well as an efferent, component to the visceral-atonomic nervous system. Despite the fundamental importance of bodily afferent information- sometimes called interoception- to central nervous system control of visceral organ function, emotional-motivational processes, and dysfunction of these processes, including psychosomatic disorders, its role did not receive much attention until quite recently. This is the first comprehensive review of this topic and it covers both neurobiological and psychobiological aspects. (...) The author first defines the issue and gives an historical background starting with the James-Lange theory of emotion, and addresses learning and motivation, roots in Pavlovian conditioning research, and operant conditioning of visceral function. In the second section he reviews recent scientific findings in the neural basis of visceral perception and studies in cardiovascular-respiratory and alimentary interoception. Finally, he discusses several related areas of research and theory including drug state issues, interoception and psychiatric disorders, and bodily consciousness, and suggests directions for future investigation. The book will be of interest to scientists in neurobiology, psychology, and brain imaging, to indivuals in related clinical fields such as psychiatry, neurology, cardiology, gastroenterology, and clinical psychology, and to their students and trainees.

Scholars and providers are coming to realize that one’s ability to notice and respond to internal body sensations contributes to an overall sense of wellbeing. Research has demonstrated a relationship between interoceptive awareness and anxiety, for example. Currently, however, tools for evaluating one’s interoception lack the conceptual foundation and clarity necessary to identify everyday behaviors that specifically reflect interoceptive awareness. Unlike existing interoceptive measures, the Sensory Profile Interoception scale is participation-based and grounded in Dunn’s Sensory Processing framework. In (...) this study we investigated concurrent validity by correlating the SPI with the Adolescent/Adult Sensory Profile ; we investigated construct validity by correlating the SPI with the Perth Alexithymia Scale, the Body Awareness Scale, and the State-Trait Anxiety Inventory. Using the REDCAP online platform, 74 college-aged participants completed the measures. Using Spearman rank order correlations there were statistically significant relationships between the corresponding sensory pattern subscales on SPI and A/ASP. The PAS was only weakly related to the registration subscale of the SPI. The BAS had significant relationships with seeking and avoiding on the SPI. The STAI had significant relationships with sensitivity and registrations of the SPI. Taken together, these findings provide evidence of construct validity of the SPI to identify participation patterns associated with both high and low interoception. With the more precise information the SPI provides, professionals can design tailored interventions to support everyday life goals and researchers can study interoception within authentic activities.

This paper advances the thesis that sensory concepts have as a semantic component the first-person indexical. It is argued that the private nature of our access to our own sensations forces, in our talking about them, an indexical reference to the inner states of the speaker in lieu of publicly accessible properties by which reference is usually fixed. Indexicals, such as ‘here’, can be understood despite ignorance of their referent. Such is the case with sensory terms. Furthermore, (...) the thesis that sensory terms are indexical has considerable explanatory power. I give two examples: firstly, I argue that clashes of intuition over Block's ‘inverted spectrum’ thought experiment can be explained by appeal to semantic properties of indexicals. Secondly, I argue that multiple realisability intuitions can be shown to be consistent with the view that sensations are type-identical with brain states. (shrink)

A major obstacle for materialist theories of the mind is the problem of sensory consciousness. How could a physical brain produce conscious sensory states that exhibit the rich and luxurious qualities of red velvet, a Mozart concerto or fresh-brewed coffee? Caging the Beast: A Theory of Sensory Consciousness offers to explain what these conscious sensory states have in common, by virtue of being conscious as opposed to unconscious states. After arguing against accounts of (...) consciousness in terms of higher-order representation of mental states, the theory claims that sensory consciousness is a special way we have of representing the world. The book also introduces a way of thinking about subjectivity as separate and more fundamental than consciousness, and considers how this foundational notion can be developed into more elaborate varieties. An appendix reviews the connection between consciousness and attention with an eye toward providing a neuropsychological instantiation of the proposed theory. (shrink)

Among psychologists, it is widely thought that infants well under age 3, monkeys, apes, birds, and dogs have been shown to have rudimentary capacities for representing and attributing mental states or relations. I believe this view to be mistaken. It rests on overinterpreting experiments. It also often rests on assuming that one must choose between taking these individuals to be mentalists and taking them to be behaviorists. This assumption underestimates a powerful nonmentalistic, nonbehavioristic explanatory scheme that centers on attributing (...) action with targets and on causation of action by interlocking, internal conative, and sensory states. Neither action with targets, nor conative states, nor sensing entails mentality. The scheme can attribute conative states and relations, efficiency, sensory states and relations, sensory retention, sensory anticipation, affect, and appreciation of individual differences. The scheme can ground explanations of false belief tests that do not require infants or nonhuman animals to use language. After the scheme is explained and applied, it is contrasted with other, superficially similar schemes proposed in the literature---for example, those of Gergely and Csibra, Wellman and Gopnik, Perner and Roessler, Flavell, and Apperly and Butterfill. Better methods for testing are briefly discussed. (shrink)

Perceptual experience seems to involve distinct intentional and qualitative features. Inasmuch as one can visually perceive that there is a Coke can in front of one, perceptual experience must be intentional. But such experiences seem to differ from paradigmatic intentional states in having introspectible qualitative character. Peacocke argues that a perceptual experience’s qualitative character is determined by intrinsic, nonrepresentational properties. But and also argues that perceptual experiences have nonconceptual representational content in addition to conceptual content and nonrepresentational sensational properties. (...) He thus distinguishes between conceptual, nonrepresentational, and nonconceptual but representational aspects of perceptual experience. I will argue that Peacocke posits too much. Contrary to his arguments, the sensational properties Peacocke claims are nonrepresentational are best construed as representational; they are best explained in terms of their relation to the perceptible properties they enable us to perceive. Since sensational properties are arguably nonconceptual, they are best construed as nonconceptual representational properties. I offer the Homomorphism View of sensory qualities, pioneered by Sellars , as a unified account of qualitative character and nonconceptual sensory representation. According to this view, a sensory quality represents a perceptible stimulus property in virtue of resembling and differing from other sensory qualities in ways parallel to the ways the stimulus property resembles and differs from other perceptible properties.

Recent philosophy of mind has seen an increase of interest in theories of intentionality in offering a functional account of mental states. The standard intentionalist view holds that mental states can be exhaustively accounted for in terms of their representational contents. An alternative view proposed by Tim Crane, called impure intentionalism, specifies mental states in terms of intentional content, mode, and object. This view is also suggested to hold for states of sensory awareness. This paper (...) primarily develops an alternative to the impure intentionalist account of states of sensory awareness. On the basis of Husserl’s phenomenological work, I argue that a focus on intentionality at the level of sensory awareness is phenomenologically implausible. The final part offers an alternative functional account of sensory awareness based on what Husserl called ‘immanent association’. (shrink)

Joint attention is typically conceptualized as a robust psychological phenomenon. In philosophy, this apparently innocuous assumption leads to the problem of accounting for the “openness” of joint attention. In psychology, it leads to the problem of justifying alternative operationalizations of joint attention, since there does not seem to be much which is psychologically uniform across different joint attentional engagements. Contrary to the received wisdom, I argue that joint attention is a social relationship which normatively regulates the attentional states of (...) two or more individuals. This social account of joint attention leans on Bart Geurts’ view of communication as commitment sharing. Its promises are: (i) to explain the role of joint attention in wider joint activities, including communicative interactions; (ii) to account for how playing this role requires individuals to deploy different psychological resources on different occasions; and (iii) to identify the rationale behind alternative operationalizations of joint attention.

Mandik (2010) defends a motor theory of control consciousness according to which nonsensory states, like motor commands, directly contribute to the awareness we have of ourselves as being in control of our actions. Along the way, he argues that his theory is to be preferred over Prinz’s (2007) sensory imagery theory, which denies that nonsensory states play any direct role in the generation of control consciousness. I argue that Mandik’s criticisms of Prinz’s theory fall short, but that (...) nonetheless there are reasons to favor a motor theory of control consciousness over a sensory imagery theory. (shrink)

A major obstacle to the acceptance of materialist theories of the mind is the problem of sensory consciousness. How could a physical brain produce conscious sensory states that exhibit the rich and luxurious qualities of red velvet, a Mozart concerto or fresh-brewed coffee? A full answer to this question requires two different sorts of theory. The first sort considers what all these conscious sensory states have in common, by virtue of being conscious as opposed to (...) unconscious states. The second sort considers what distinguishes conscious sensory-states from each other, for example, how the qualities in a conscious sensory state of red velvet differ from those of a Mozart concerto. I propose a theory of the first sort, that is, an explanation of the distinction between conscious and unconscious sensory states. ;According to the second sense theory, conscious sensory states are coordinated sensory representations of the present moment produced by a second sense. Three elements are necessary and jointly sufficient for sensory consciousness. Sensory representations must be coordinated toward action in the world. The representations included in the content of a conscious sensory state are those that will aid the creature in assessing current environmental conditions according to the task at hand. Conscious sensory states represent states of affairs as occurring at the present moment. In other words, sensory consciousness is constituted by the coordination of sensory representations into a representation of what is happening 'now.' The mechanism responsible for coordinating sensory representations into conscious sensory states is the second sense. A second sense mechanism explains how some sensory representations become coordinated into a conscious sensory state while others remain unconscious. ;In addition to providing an explanation of sensory consciousness, the second sense theory is nicely suited to a Gibsonian account of subjectivity, whereby information about the subject is specified simultaneously in perception with information about the object. I argue that the subject, at its most bare, is the locus of an egocentric map, the zero point of a coordinate system which specifies objects according to here. (shrink)
