Perceptual diversity allows human beings to access knowledge through a variety of perceptual processes, rather than merely through everyday waking reality. Many of these perceptual processes are transrational altered states of consciousness (meditation, trance, dreams, imagination) and are not considered valid processes for accessing knowledge by science (which is based primarily upon quantification, reductionism, and the experimental method). According to Erika Bourguignon's (1973) research in the 1970s, approximately 90 percent of cultures have institutionalized forms of altered (...) states of consciousness, meaning that such types of consciousness are to be found in most human societies and are "normal." Now, however, transrational consciousness is being devalued in many societies as it is simultaneously being replaced by the monophasic consciousness of "developed" nations. Not only are we are losing (1) biodiversity (biocomplexity) in environments and (2) cultural diversity in societies, we also are losing (3) perceptual diversity in human cognitive processes. All three losses of diversity (bio, cultural, and cognitive) are interrelated.Cultures that value perceptual diversity are more adaptable than cultures that do not. Perceptually diverse cultures are better able to understand whole systems (because they use a variety of perceptual processes to understand systems) than are cultures that rely only on the scientific method, which dissects systems. They also are better stewards of their environments, because they grasp the value of the whole of biodiversity (biocomplexity) through transrational as well as scientific processes. Understanding through perceptual diversity leads to a higher degree of adaptability and evolutionary competence.From the perspective of an anthropologist who has worked with development organizations, development will continue to destroy perceptual diversity because it exports the dominant cognitive process of "developed" nations, i.e., monophasic consciousness. Destroying perceptual diversity, in turn, leads to the destruction of cultural diversity and biocomplexity. Drawing from research I conducted among traditional healers in Namibia, I conclude that development organizations need to listen to those who use transrational perceptual processes and also need to find a way to incorporate and validate perceptual diversity in their theoretical and applied frameworks.

Perceptual malleability and diversity can stem from perceptual learning, expertise, genetics, disease, or accident. Perceptual malleability and diversity force us to reject the claim that perceptual capacities, perceptual experience, and perceptual content are universal across subjects and times. And it casts doubt on the presumption of a universal human perceptual nature. However, it does not directly challenge perceptual objectivity, understood as the claim that one can perceive a world of things (...) and features that are independent from oneself and one's experiences and that could be perceived by other subjects.

The literature contains a disconnect between accounts of how humans learn lexical semantic representations for words. Theories generally propose that lexical semantics are learned either through perceptual experience or through exposure to regularities in language. We propose here a model to integrate these two information sources. Specifically, the model uses the global structure of memory to exploit the redundancy between language and perception in order to generate inferred perceptual representations for words with which the model has no (...) class='Hi'>perceptual experience. We test the model on a variety of different datasets from grounded cognition experiments and demonstrate that this diverse set of results can be explained as perceptual simulation (cf. Barsalou, Simmons, Barbey, & Wilson, 2003) within a global memory model. (shrink)

Several theories link consciousness to complex cortical dynamics, as suggested by comparison of brain signal diversity between conscious states and states where consciousness is lost or reduced. In particular, Lempel-Ziv complexity, amplitude coalition entropy and synchrony coalition entropy distinguish wakefulness and REM sleep from deep sleep and anesthesia, and are elevated in psychedelic states, reported to increase the range and vividness of conscious contents. Some studies have even found correlations between complexity measures and facets of self-reported experience. As suggested (...) by integrated information theory and the entropic brain hypothesis, measures of differentiation and signal diversity may therefore be measurable correlates of consciousness and phenomenological richness. Inspired by these ideas, we tested three hypotheses about EEG signal diversity related to sleep and dreaming. First, diversity should decrease with successively deeper stages of non-REM sleep. Second, signal diversity within the same sleep stage should be higher for periods of dreaming vs. non-dreaming. Third, specific aspects of dream contents should correlate with signal diversity in corresponding cortical regions. We employed a repeated awakening paradigm in sleep deprived healthy volunteers, with immediate dream report and rating of dream content along a thought-perceptual axis, from exclusively thought-like to exclusively perceptual. Generalized linear mixed models were used to assess how signal diversity varied with sleep stage, dreaming and thought-perceptual rating. Signal diversity decreased with sleep depth, but was not significantly different between dreaming and non-dreaming, even though there was a significant positive correlation between Lempel-Ziv complexity of EEG recorded over the posterior cortex and thought-perceptual ratings of dream contents.

In many critical investigations of machine vision, the focus lies almost exclusively on dataset bias and on fixing datasets by introducing more and more diverse sets of images. We propose that machine vision systems are inherently biased not only because they rely on biased datasets but also because theirperceptual topology, their specific way of representing the visual world, gives rise to a new class of bias that we callperceptual bias. Concretely, we define perceptual topology as the set of those (...) inductive biases in machine vision systems that determine its capability to represent the visual world. Perceptual bias, then, describes the difference between the assumed “ways of seeing” of a machine vision system, our reasonable expectations regarding its way of representing the visual world, and its actual perceptual topology. We show how perceptual bias affects the interpretability of machine vision systems in particular, by means of a close reading of a visualization technique called “feature visualization”. We conclude that dataset bias and perceptual bias both need to be considered in the critical analysis of machine vision systems and propose to understand critical machine vision as an important transdisciplinary challenge, situated at the interface of computer science and visual studies/Bildwissenschaft.

Professor Campbell Garnett has here presented a history, critique and synthesis of several widely diverse philosophical methods and conclusions. With great simplicity he gives an account of the genesis of idealism and the early twentieth century reaction towards realism, highlighting William James’ ‘Does Consciousness Exist’ and G E Moore’s ‘Refutation of Idealism’. Two methods involved are singled out: introspection, emphasised by the ‘acknowledged master of this art’, James and Moore’s linguistic analysis, leading to the analysis of ordinary language and the (...) attempt to develop an ideal language. The author then proposes the analysis of mental life as the most important and central task of the philosopher.. In proof of the validity of this method, it is said that ‘All the various departments of philosophy are analyses of different parts or phases of mental life. Logic is an analysis of the processes of statements and inference; ethics is an analysis of the moral consciousness, and aesthetics of the aesthetic consciousness; epistemology is an analysis of the processes of perception and conception’. This seems to me misleading; the author has already associated analysis of mental life with armchair psychology; and can ‘analysis’ be used to cover critical evaluation? This characterisation of the task of philosophy leads to seeing phenomenology, as ‘a technique in which reflective analysis of the categories is sharpened by the setting aside of other questions’ which is very vague; ‘analysis of ordinary language’ is said to be ‘an analysis of meaning, not in the objective sense of the usage of words as described in the dictionary, but in the subjective sense of their use, of what the use means or intends to do by framing and uttering his sentences’. It also leads to that conflation of philosophy of mind and epistemology/ontology which leads to much confusion, and which it has been the achievement of contemporary philosophy on both sides of the linguistic divide to disentangle.

This paper defends two theses about sensory objects. The more general thesis is that directly sensed objects are those delivered by sub-personal processes. It is shown how this thesis runs counter to perceptual atomism, the view that wholes are always sensed indirectly, through their parts. The more specific thesis is that while the direct objects of audition are all composed of sounds, these direct objects are not all sounds—here, a composite auditory object is a temporal sequence of sounds (whereas (...) a composite visual object is a spatial composite). Many composite objects are directly heard in the sense just mentioned. There is a great variety of such composite auditory objects—melodies, harmonies, sequences of phonemes, individual voices, meaning-carrying sounds, and so on. This diversity of auditory objects has an important application to aesthetics. Perceivers do not naturally or easily attend simultaneously to auditory objects that overlap in time. Yet, aesthetic appreciation depends on such an allocation of attention to overlapping objects. (shrink)

Despite decades of study, mimicry continues to inspire and challenge evolutionary biologists. This essay aims to assess recent conceptual frameworks for the study of mimicry and to examine the links between mimicry and related phenomena. Mimicry is defined here as similarity in appearance and/or behavior between a mimic and a model that provides a selective advantage to the mimic because it affects the behavior of a receiver causing it to misidentify the mimic, and that evolved (or is maintained by selection) (...) because of those effects. Mimics copy cues or signals that are already in use as part of a stable communication system, but offer misleading information to receivers. Mimicry overlaps, both conceptually and evolutionarily, with camouflage and perceptual exploitation but the overlap is only partial, which may create some confusion. Certain types of camouflage (e.g. masquerade) conform to the definition of mimicry, while others (e.g. background matching) are not considered mimicry because they prevent detection rather than recognition of the camouflaged animal. Mimicry, on the other hand, works by exploiting peculiarities of the receiver at higher stages of sensory processing involving recognition and classification of stimuli. Perceptual exploitation models of trait evolution are also closely related to mimicry, and sensory traps in particular may act as a precursor for true mimicry to evolve. The common thread through these diverse phenomena is deception of a receiver by a mimic. Thus receiver deception (i.e. perceptual error) emerges as a key characteristic of mimicry shared with some types of camouflage and perceptual exploitation. (shrink)

The main aim of this article is to present and defend a thesis according to which conceptual representations of some types of mental states are encoded in the same neural structures that underlie the first-personal experience of those states. To support this proposal here, I will put forth a novel account of the cognitive function played by ‘shared representations’ of emotions and bodily sensations, i.e. neural structures that are active when one experiences a mental state of a certain type as (...) well as when one observes someone else experiencing a state of the same type. I will argue that shared representations in fact constitute vehicles of certain mental state concepts (more precisely, concepts of specific types of emotions and somatosensory states). The main line of arguing for this will consist in showing that shared representations exhibit specific, ‘conceptual’ functional properties:(1) causal effect on forming metacognitive judgments, (2) cognitive penetrability, (3) diversity of input types.

Suboptimality of decision making needs no explanation. High level accounts of suboptimality in diverse tasks cannot add up to a mechanistic theory of perceptual decision making. Mental processes operate on the contents of information brought by the experimenter and the participant to the task, not on the amount of information in the stimuli without regard to physical and social context.

In recent years, scientists have increasingly taken to investigate the predictive nature of cognition. We argue that prediction relies on abstraction, and thus theories of predictive cognition need an explicit theory of abstract representation. We propose such a theory of the abstract representational capacities that allow humans to transcend the “here-and-now.” Consistent with the predictive cognition literature, we suggest that the representational substrates of the mind are built as ahierarchy, ranging from the concrete to the abstract; however, we argue that (...) there are qualitative differences between elements along this hierarchy, generating meaningful, often unacknowledged,diversity.Echoing views from philosophy, we suggest that the representational hierarchy can be parsed into:modality-specificrepresentations, instantiated on perceptual similarity;multimodalrepresentations, instantiated primarily on the discovery of spatiotemporal contiguity; andcategoricalrepresentations, instantiated primarily on social interaction. These elements serve as the building blocks ofcomplex structures discussed in cognitive psychology (e.g., episodes, scripts) and are the inputs for mental representations that behave like functions, typically discussed in linguistics (i.e.,predicators). We support our argument for representational diversity by explaining how the elements in our ontology are all required to account for humans’ predictive cognition (e.g., in subserving logic-based prediction; in optimizing the trade-off between accurate and detailed predictions) and by examining how the neuroscientific evidence coheres with our account. In doing so, we provide a testable model of the neural bases of conceptual cognition and highlight several important implications to research on self-projection, reinforcement learning, and predictive-processing models of psychopathology.

William Alston's Perceiving God: The Epistemology of Religious Experience is a most significant contribution to the philosophy of religion. The product of 50 years' reflection on its topic , this work provides a very thorough explication and defence of what Alston calls the ‘mystical perceptual practice’ – the practice of forming beliefs about the Ultimate on the basis of putative ‘direct experiential awareness’ thereof . Alston argues, in particular, for the rationality of engaging in the Christian form of MP (...) . On his view, those who participate in CMP are justified in forming beliefs as they do because their practice is ‘socially established’, has a ‘functioning overrider system’ and a ‘significant degree of self-support’; and because of the ‘lack of sufficient reasons to take the practice as unreliable’.

The umbrella-term ‘executive functions’ includes various domain-general, goal-directed cognitive abilities responsible for behavioral self-regulation. The influential unity and diversity model of EF posits the existence of three correlated yet separable executive domains: inhibition, shifting and updating. These domains may be influenced by factors such as socioeconomic status and culture, possibly due to the way EF tasks are devised and to biased choice of stimuli, focusing on first-world testees. Here, we propose a FREE test battery that includes two open-access tasks (...) for each of the three abovementioned executive domains to allow latent variables to be obtained. The tasks were selected from those that have been shown to be representative of each domain, that are not copyrighted and do not require special hardware/software to be administered. These tasks were adapted for use in populations with varying SES/schooling levels by simplifying tasks/instructions and using easily recognized stimuli such as pictures. Items are answered verbally and tasks are self-paced to minimize interference from individual differences in psychomotor and perceptual speed, to better isolate executive from other cognitive abilities. We tested these tasks on 146 early adolescents of both sexes and varying SES, because this is the age group in which the executive domains of interest become distinguishable and in order to confirm that SES effects were minimized. Performance was determined by Rate Correct Scores, which consider speed-accuracy trade-offs. Scores were sensitive to the expected improvement in performance with age and rarely/inconsistently affected by sex and SES, as expected, with no floor or ceiling effects, or skewed distribution, thus suggesting their adequacy for diverse populations in these respects. Using structural equation modeling, evidence based on internal structure was obtained by replicating the three correlated-factor solution proposed by the authors of the model. We conclude that the FREE test battery, which is open access and described in detail, holds promise as a tool for research that can be adapted for a wide range of populations, as well as altered and/or complemented in coming studies.

This paper answers a philosophical challenge that emerges when we problematize the seemingly trivial "fact" that, on the one hand, through our senses we are presented with a realm that is not of our own making; while, on the other hand, various perceivers are acquainted with diverse presentations of this realm, depending on their perspective and cognitive machinery. The challenge is dubbed here the problem of presentations. The paper draws on the idea of situation-dependent properties proposed by Susanna Schellenberg. However, (...) the paper takes the notion of situation more seriously and introduces a number of basic notions borrowed from situated cognition—a cluster of ideas that have recently emerged in the philosophy of mind. These make it possible to introduce the perceiver in such a way as not to endanger the objective character of situation-dependent properties. Thought of this way, situation-dependent properties are in turn described as the building blocks of presentations. (shrink)

The purpose of this study was to explain differences between employees who feel a sense of belonging and those who feel a sense of otherness in terms of their opinions about diversity works in their organizations. We conducted an empirical study to examine the perceptual differences between two independent groups of the study “who feel a sense of belonging” and “who feel a sense of otherness.” We collected data from 792 employees working for organizations in different sizes, industries, (...) and capital structures, which enriched the representativeness of the sample. The findings show that out-group members remain less satisfied with diversity works in their organizations based on four main issues such as “competence of diversity actors,” “embeddedness of diversity works in organizational policies/practices,” “diversity awareness in the HRM functions,” and “diversity-related employee satisfaction.” This paper makes two contributions. First, it contributes to the extant literature an understanding of the differences between those who remain indifferent to diversity works and those who care to see, speak, and hear about them. Second, with a few exceptions, extant studies on diversity works have been dominated by Western-centered research. Research is needed on countries with different macro-contextual conditions, such as different legal regulations, socio-political status, and history. For this study, survey data were collected from people who work in Turkey, a country which has limited legal measures and underdeveloped discourses for equality, diversity, and inclusion. The paper provides significant insights into leading diversity works in national settings with less developed supportive mechanisms for diversity. (shrink)

This paper aims to contribute to a defense of the now quite familiar argument from the perceptual model of religious experience (hereafter PMR) to the rationality of beliefs formed on the basis of religious experience. The contribution will not, however, come in the form of a positive argument for PMR. Neither will this contribution take the form of a response to key objections to the plausibility of that model. Instead, I wish to argue that there is a widespread assumption (...) about the role of concepts in perceptual experience generally which, when assimilated by PMR, complicates the attempt to respond to the most serious objection to the argument from PMR to the rationality of religious belief—viz. the objection from conflicting religious claims. Again, this paper will not respond to the objection from conflicting religious claims. Rather, it will explain how a common assumption makes that problem worse (or even intractable) and it will offer a positive suggestion about how to avoid that common assumption. Of course, to have shown how not to make a problem worse is not yet to have solved the problem. But, if the argument of this paper succeeds, it is a crucial first step. In what follows, I will (i) very briefly summarize the role of PMR in an argument for the rationality of religious belief, (ii) state the problem of conflicting religious claims, (iii) explain how a widespread assumption about the role of concepts in perceptual experience exacerbates the problem and (iv) offer the beginnings of an alternative account of the role of concepts in perceptual experience and comment on the evidential force of religious experience construed along the lines of this alternative account. Of course, an adequate treatment of the points in (iv) would require far more attention than can be devoted to them here. The primary burden of this paper is to establish the critical point in (iii), i.e., to generate some dissatisfaction with the “widespread assumption,” and to use this dissatisfaction as a motivation for exploring an alternative account of conceptual contribution.

This study investigated the relative contribution of perception/cognition and language-specific semantics in nonverbal categorization of spatial relations. English and Korean speakers completed a video-based similarity judgment task involving containment, support, tight fit, and loose fit. Both perception/cognition and language served as resources for categorization, and allocation between the two depended on the target relation and the features contrasted in the choices. Whereas perceptual/cognitive salience for containment and tight-fit features guided categorization in many contexts, language-specific semantics influenced categorization where the (...) two features competed for similarity judgment and when the target relation was tight support, a domain where spatial relations are perceptually diverse. In the latter contexts, each group categorized more in line with semantics of their language, that is, containment/support for English and tight/loose fit for Korean. We conclude that language guides spatial categorization when perception/cognition alone is not sufficient. In this way, language is an integral part of our cognitive domain of space. (shrink)

At the center of both Humean and Kantian experience is a connection between the objectivity of perception and the concept of substantial identity. In the course of examining both systems as responses to structurally similar problems of perceptual objectivity, I argue that Kant's conception of substantial persistence is superior to Hume's account of the idea of identity. ;There are deep tensions in Hume's account of perception that are partially explicable in terms of his complex and naturalistic 'moderate scepticism' and (...) the conflict in the faculties of causal reasoning and imagination upon which it rests. Despite the subtlety of his explanatory scepticism, however, there remains a damaging vacillation in Hume between perceptible phenomena understood as the objects of 'vulgar' direct realism on the one hand, and as the subjective images of the causal-representationalist philosophy on the other. There are also difficulties with Hume's idea of perfect identity, the foundation of both the vulgar and philosophical systems of belief in body. Starting from an assumption of radical perceptual diversity, Hume unsuccessfully attempts to build an idea of substantial identity upon the fiction of a duration without change. ;The tension in Hume concerning the direct objects of perception is paralleled by the subjective/objective ambiguity of Kant's perceptual content terms. In Kant, however, the ambiguity reflects a coherent account of conceptualization, perceptual judgment, and self-conscious temporal experience. I examine Kant's arguments for the persistence and absolute permanence of substance and show that they are largely successful if premises are supplied from the general account of objective judgment and the unity of consciousness. ;Hume's theory of perceptual belief is ingenious but ultimately unsatisfactory according to his own criteria. His failure to construct an idea of identity upon a fictitious duration casts favorable light on Kant's contention that substantial identity is a condition on having any cognition of duration. The two philosophers' dispute concerning identity is conceptually connected to their differing treatments of the 'given' element in perception. (shrink)

Perceptual processes differ from cognitive, this paper argues, in functioning to be causally controlled by proximal stimuli, and being modular, at least in a modest sense that excludes their being isotropic in Jerry Fodor's sense. This claim agrees with such theorists as Jacob Beck and Ben Phillips that a function of stimulus-control is needed for perceptual status. In support of this necessity claim, I argue, inter alia, that E.J. Green's recent architectural account misclassifies processes deploying knowledge of grammar (...) as perceptual. _Pace_ Beck and Phillips, however, I argue a function of stimulus-control is insufficient for perceptual as opposed to cognitive status. One consideration in favour of such insufficiency, noted but (I argue) not convincingly rebutted by these theorists, concerns perpetually grounded demonstrative thought. Two other considerations trade on the fact that a function of stimulus-control can arise not from blind nature but intentional design or social institutions, where so-functioning processes may but need not be perceptual. I offer two cases where such processes are cognitive, viz. skilful play-by-play announcing of ongoing events, and voluntary visualizing of ongoing events under the guidance of apt play-by-play announcements, dubbed announcement-driven visualizing (ADV). The cognitive status of these three diverse phenomena cannot be explained by an absence of a perception-like representational format or content (for ADV has such) or by a presence of personal-level mental states causally mediating between stimuli and outputs (for perception has such). A bettter explanation invokes, I argue, the non-modular character of the generating process. (shrink)

The diverse essays in this volume speak to the relevance of phenomenological and psychological questioning regarding perceptions of the human. This designation, human, can be used beyond the mere identification of a species to underwrite exclusion, denigration, dehumanization and demonization, and to set up a pervasive opposition in Othering all deemed inhuman, nonhuman, or posthuman. As alerted to by Merleau-Ponty, one crucial key for a deeper understanding of these issues is consideration of the nature and scope of perception. Perception defines (...) the world of the perceiver, and perceptual capacities are constituted in engagement with the world – there is co-determination. Moreover, the distinct phenomenology of perception in the spectatorial mode in contrast to the reciprocal mode, deepens the intersubjective and ethical dimensions of such investigations. -/- Questions motivating the essays include: Can objectification and an inhuman gaze serve positive ends? If so, under what constraints and conditions? How is an inhuman gaze achieved and at what cost? How might the emerging insights of the role of perception into our interdependencies and essential sociality from various domains challenge not only theoretical frameworks, but also the practices and institutions of science, medicine, psychiatry and justice? What can we learn from atypical social cognition, psychopathology and animal cognition? Could distortions within the gazer’s emotional responsiveness and habituated aspects of social interaction play a role in the emergence of an inhuman gaze? -/- Perception and the Inhuman Gaze will interest scholars and advanced students working in phenomenology, philosophy of mind, psychology, psychiatry, sociology and social cognition. -/- Table of Contents -/- Introduction -/- Part I.

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)

This chapter first argues against the widely accepted “mentalist” interpretation of Aristotle’s conception of the perception of external objects. On that view, the perception of objects results from an act of synthesis of the diverse perceptual input provided by the different sense modalities. I argue that Aristotle’s conception of perception does not require such mental “construction” of external objects. For him, we unfailingly perceive external objects by way of modally specific perception: perception without qualification is primarily of external 3-D (...) objects, while modally specific perception is of perceptual qualities. As the special senses cannot operate in isolation from the perceptual system as a whole, it follows that we see colors, hear sounds, etc., and thereby perceive the objects whose colors and sounds they are. The second part offers a causal interpretation of Aristotle’s definition of perception as “reception of the form without the matter,” according to which the causal history of sensory affection fixes the content of the resulting act of perception: perception is cognitive in virtue of being the matterless presence of external things’ qualities in the perceiver.

We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted from sensory input to their basal and perisomatic synapses can be amplified when relevant. We argue that apical amplification (...) enables conscious perceptual experience and makes it more flexible, and thus more adaptive, by being sensitive to context. Apical amplification provides a possible mechanism for recurrent processing theory that avoids strong loops. It makes the broadcasting hypothesized by global neuronal workspace theories feasible while preserving the distinct contributions of the individual cells receiving the broadcast. It also provides mechanisms that contribute to the holistic aspects of integrated information theory. As apical amplification is highly dependent on cholinergic, aminergic, and other neuromodulators, it relates the specific contents of conscious experience to global mental states and to fluctuations in arousal when awake. We conclude that apical dendrites provide a cellular mechanism for the context-sensitive selective amplification that is a cardinal prerequisite of conscious perception. (shrink)

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative, explanation for visual multistability – that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related (...) to the expression of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non-visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non-sensory brain centers. Such direct intervention in the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

Object perception deploys a suite of perceptual capacities that constrains attention, guides reidentification, subserves recognition, and anchors demonstrative thought. Objects for perception—perceptual objects—are the targets of such capacities. Characterizing perceptual objects for multisensory perception faces two puzzles. First is the diversity of objects across sensory modalities. Second is the unity of multisensory perceptual objects. This paper resolves the puzzles. Objects for perception are structured mereologically complex individuals. Perceptual objects are items that bear perceptible features (...) and have perceptible parts arranged to form a unified whole. This circumscribes the targets of object perception where neutral talk concerning intentional objects and objects of perception cannot. Nonetheless, it is more permissive than identifying perceptual objects with material bodies, which excludes too much and leans too heavily on vision. The account thus is tailored to capture the role of objects in perception beyond vision: tactual, auditory, and olfactory objects are individuals with differing structures. Its flexibility also enables the account to accommodate shared objects for multisensory perception: multisensory perceptual objects are mereologically complex individuals with hybrid structure. For instance, one can bimodally perceive a common whole with parts accessible to one but not both modalities. Each sense provides a partial perspective on a complex whole that is perceptible through the coordinated use of multiple senses. Understanding perceptual objects as structured mereologically complex individuals thus provides a theoretically useful notion of an object for multisensory perception that resolves the puzzles of diversity and of unity.

This article draws on the ethnography of Aboriginal Australia to argue that perceptual openness, extending from waking life into dreaming experience, provides an important cognitive framework for the apprehension of dreamt experience in these contexts. I argue that this perceptual openness is analogous to the “openness to experience” described as a personality trait that had been linked with dream recall frequency. An implication of identifying perceptual openness at a cultural rather than at an individual level is two-fold. (...) It provides an example of the ways in which cultural differences affect perception, indicative of cognitive diversity; and, given the relationship between dreams and creativity suggested anecdotally and through research, a cultural orientation toward perceptual openness is also likely to have implications for the realization of creativity that occurs through dreams. Such creativity though cannot be separated from the relational context in which such dreamt material is elaborated and understood. (shrink)

The diversity of designs and techniques used to build environments around the human perceptual system in order to immerse people in complex synthetic experiences has created a variety of approaches. Some of the experiences may immerse the person in structures that cannot be physically accessed otherwise because of scale or time. Others may bring together different phenomena that do not normally happen simultaneously. In this article I attempt to categorize the kinds of experiences that are being built around (...) our bodies and minds utilizing devices that extend our senses and cognitive structures, thus mediating the way we experience and think to better understand the world around us.

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)

This volume is a collective exploration of major themes in the work of Crispin Wright, one of today's leading philosophers. These newly commissioned papers are divided into four sections, preceded by a substantial Introduction, which places them in the context of the development of Wright's ideas. The distinguished contributors address issues such as the rule-following problem, knowledge of our meanings and minds, truth, realism, anti-realism and relativism, as well as the nature of perceptual justification, the cogency of arguments such (...) as G. E. Moore's celebrated proof of an external world, and skepticism about the material world. Some papers explore the relationship of Wright's ideas with those of Ludwig Wittgenstein, whose influence has always been a prominent aspect of Wright's philosophy. The essays collectively testify to the enormous interest and relevance of Wright's seminal contributions for present-day debates in areas as diverse as the philosophy of language and mind, metaphysics, and epistemology, and significantly advance research in these areas. The volume also contains Wright's substantial responses to his critics, which offer the most up-to-date versions of his ideas and a vigorous defense of his philosophy. (shrink)

To what extent does perceptual language reflect universals of experience and cognition, and to what extent is it shaped by particular cultural preoccupations? This paper investigates the universality~relativity of perceptual language by examining the use of basic perception terms in spontaneous conversation across 13 diverse languages and cultures. We analyze the frequency of perception words to test two universalist hypotheses: that sight is always a dominant sense, and that the relative ranking of the senses will be the same (...) across different cultures. We find that references to sight outstrip references to the other senses, suggesting a pan-human preoccupation with visual phenomena. However, the relative frequency of the other senses was found to vary cross-linguistically. Cultural relativity was conspicuous as exemplified by the high ranking of smell in Semai, an Aslian language. Together these results suggest a place for both universal constraints and cultural shaping of the language of perception. (shrink)

In informal terms, abductive reasoning involves inferring the best or most plausible explanation from a given set of facts or data. It is a common occurrence in everyday life and crops up in such diverse places as medical diagnosis, scientific theory formation, accident investigation, language understanding, and jury deliberation. In recent years, it has become a popular and fruitful topic in artificial intelligence research. This volume breaks new ground in the scientific, philosophical, and technological study of abduction. It presents new (...) ideas about inferential and information-processing foundations for knowledge and certainty. The authors argue that knowledge arises from experience by processes of abductive inference, in contrast to the view that it arises non-inferentially, or that deduction and inductive generalization are enough to account for knowledge. Much AI research is hypothetical, so the importance of this book is that it reports key discoveries about abduction that have been made as a result of designing, building, testing, and analyzing actual working knowledge-based systems for medical diagnosis and other abductive tasks. The book tells the story of six generations of increasingly sophisticated generic abduction machines, RED-1, RED-2, PEIRCE, MDX2, TIPS, QUAWDS, and the discovery of reasoning strategies that make it computationally feasible to form well-justified composite explanatory hypotheses, despite the threat of combinatorial explosion. The final chapter argues that perception is logically abductive and presents a layered-abduction computational model of perceptual information processing. This book will be of great interest to researchers in AI, cognitive science, and philosophy of science. (shrink)

It is a commonplace that the modern world cannot be experienced as enchanted--that the very concept of enchantment belongs to past ages of superstition. Jane Bennett challenges that view. She seeks to rehabilitate enchantment, showing not only how it is still possible to experience genuine wonder, but how such experience is crucial to motivating ethical behavior. A creative blend of political theory, philosophy, and literary studies, this book is a powerful and innovative contribution to an emerging interdisciplinary conversation about the (...) deep connections between ethics, aesthetics, and politics. As Bennett describes it, enchantment is a sense of openness to the unusual, the captivating, and the disturbing in everyday life. She guides us through a wide and often surprising range of sources of enchantment, showing that we can still find enchantment in nature, for example, but also in such unexpected places as modern technology, advertising, and even bureaucracy. She then explains how everyday moments of enchantment can be cultivated to build an ethics of generosity, stimulating the emotional energy and honing the perceptual refinement necessary to follow moral codes. Throughout, Bennett draws on thinkers and writers as diverse as Kant, Schiller, Thoreau, Kafka, Marx, Weber, Adorno, and Deleuze. With its range and daring, The Enchantment of Modern Life is a provocative challenge to the centuries-old ''narrative of disenchantment,'' one that presents a new ''alter-tale'' that discloses our profound attachment to the human and nonhuman world.

Mental imagery is perceptual processing that is not triggered by corresponding sensory stimulation in the relevant sense modality. Temporal mental imagery is perceptual processing that is not triggered by temporally corresponding sensory stimulation in the relevant sense modality. We aim to show that temporal mental imagery plays an important role in explaining a number of diverse mental phenomena, from the thickness of temporal experience and the specious present to episodic memory and postdictive perception.

Marr (1982) may have been one of the rst vision researchers to insist that in modeling vision it is important to separate the location of visual features from their type. He argued that in early stages of visual processing there must be “place tokens” that enable subsequent stages of the visual system to treat locations independent of what specic feature type was at that location. Thus, in certain respects a collinear array of diverse features could still be perceived as a (...) line, and under certain conditions could function as such in perceptual phenomena like the Poggendorf illusion.

It is widely held that intuitive dualism—an implicit default mode of thought that takes minds to be separable from bodies and capable of independent existence—is a human universal. Among the findings taken to support universal intuitive dualism is a pattern of evidence in which “psychological” traits (knowledge, desires) are judged more likely to continue after death than bodily or “biological” traits (perceptual, physiological, and bodily states). Here, we present cross-cultural evidence from six study populations, including non-Western societies with diverse (...) belief systems, that shows that while this pattern exists, the overall pattern of responses nonetheless does not support intuitive dualism in afterlife beliefs. Most responses of most participants across all cultures tested were not dualist. While our sample is in no way intended to capture the full range of human societies and afterlife beliefs, it captures a far broader range of cultures than in any prior study, and thus puts the case for afterlife beliefs as evidence for universal intuitive dualism to a strong test. Based on these findings, we suggest that while dualist thinking is a possible mode of thought enabled by evolved human psychology, such thinking does not constitute a default mode of thought. Rather, our data support what we will call intuitive materialism—the view that the underlying intuitive systems for reasoning about minds and death produce as a default judgment that mental states cease to exist with bodily death.

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related (...) to the expression of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

ABSTRACTThe central hypothesis of this paper is that the phenomenology of Merleau-Ponty offers significant philosophical groundwork for an ethics that honours key feminist commitments – embodiment, situatedness, diversity and the intrinsic sociality of subjectivity. Part I evaluates feminist criticisms of Merleau-Ponty. Part II defends the claim that Merleau-Ponty’s non-dualist ontology underwrites leading approaches in feminist ethics, notably Care Ethics and the Ethics of Vulnerability. Part III examines Merleau-Ponty’s analyses of embodied percipience, arguing that these offer a powerful critique of (...) the view from nowhere, a totalizing God’s-eye-view with pretensions to objectivity. By revealing the normative structure of perceptual gestalts in the intersubjective domain, he establishes the view from everywhere. Normativity is no longer deferred to higher authorities such as duty, utility or the valorized virtue, but through the perceptual gestalt it is returned to the perceiving embodied subject. This...

It is difficult to find agreement on what constitutes perceiving.at Rovereto, Italy. The term is used in a wide array of domains ranging from psychology to physiology to aesthetics, and over time it has also acquired diverse connotations within various disciplines. Current perceptual science, however, even when it deals with qualitative aspects of experience, for example phenomena of lightness and colour, almost exclusively explains them in terms of primary qualities or stimuli quantitatively understood. The fact that science treats qualitative (...) experiences in terms of stimuli is important, because almost nothing of phenomenal perception as such is quantitative in nature. The paper argues for a qualitative science of perceiving, its methodology, its laws, and its possible developments. (shrink)

One of the chief innovations in medieval adaptations of Aristotelian psychology was the expansion of Aristotle's notion of imagination orphantasiato include a variety of distinct perceptual powers known collectively as the internal senses. Amongst medieval philosophers in the Arabic world, Avicenna offers one of the most complex and sophisticated accounts of the internal senses. Within his list of internal senses, Avicenna includes a faculty known as “estimation”, to which various functions are assigned in a wide variety of contexts. Although (...) many philosophers in the Arabic world as well as in the Latin West accepted Avicenna's positing of an estimative faculty, Avicenna's best-known critics, al-Ghazâlî and Averroes, found Avicenna's arguments in support of a distinct estimative faculty problematic. For different reasons, both Averroes and Ghazâlî raised the basic question of whether one needed to posit a distinct faculty of estimation to supplement the perceptual abilities of the other internal senses, and whether the notion of an estimative power as defined by Avicenna was internally coherent. Such criticisms suggest that the Avicennian conception of estimation is not entirely unambiguous, and that a correct understanding of Avicenna's motivations for delineating an estimative power requires a careful study of the diverse activities assigned to it throughout Avicenna's philosophical writings.

It is through touch that we are able to interact directly with the world; it is our primary conduit of both pleasure and pain. Touch may be our most immediate and powerful sense—“the first sense" because of the central role it plays in experience. In this book, Matthew Fulkerson proposes that human touch, despite its functional diversity, is a single, unified sensory modality. Fulkerson offers a philosophical account of touch, reflecting the interests, methods, and approach that define contemporary philosophy; (...) but his argument is informed throughout by the insights and constraints of empirical work on touch. Human touch is a multidimensional object of investigation, Fulkerson writes, best served by using a variety of methods and approaches. -/- To defend his view of the unity of touch, Fulkerson describes and argues for a novel, unifying role for exploratory action in touch. He goes on to fill in the details of this unified, exploratory form of perception, offering philosophical accounts of tool use and distal touch, the representational structure of tangible properties, the spatial content of touch, and the role of pleasure in tactual experience. -/- Fulkerson’s argument for the unique role played by exploratory action departs notably from traditional vision-centric philosophical approaches to perception, challenging the received view that action plays the same role in all sensory modalities. The robust philosophical account of touch he offers in The First Sense has significant implications for our general understanding of perception and perceptual experience. (shrink)

Abstract“Sign stimuli” elicit specific patterns of behavior when an organism's motivation is appropriate. In the toad, visually released prey-catching involves orienting toward the prey, approaching, fixating, and snapping. For these action patterns to be selected and released, the prey must be recognized and localized in space. Toads discriminate prey from nonprey by certain spatiotemporal stimulus features. The stimulus-response relations are mediated by innate releasing mechanisms (RMs) with recognition properties partly modifiable by experience. Striato-pretecto-tectal connectivity determines the RM's recognition and localization (...) properties, whereas medialpallio-thalamo-tectal circuitry makes the system sensitive to changes in internal state and to prior history of exposure to stimuli. RMs encode the diverse stimulus conditions referring to the same prey object through different combinations of “specialized” tectal neurons, involving cells selectively tuned to prey features. The prey-selective neurons express the outcome of information processing in functional units consisting of interconnected cells. Excitatory and inhibitory interactions among feature-sensitive tectal and pretectal neurons specify the perceptual operations involved in distinguishing the prey from its background, selecting its features, and discriminating it from predators. Other connections indicate stimulus location. The results of these analyses are transmitted by specialized neurons projecting from the tectum to bulbar/spinal motor systems, providing a sensorimotor interface. Specific combinations of such projective neurons – mediating feature- and space-related messages – form “command releasing systems” that activate corresponding motor pattern generators for appropriate prey-catching action patterns.

Because the visual system cannot process all of the objects, colors, and features present in a visual scene, visual attention allows some visual stimuli to be selected and processed over others. Most research on visual attention has focused on spatial or location-based attention, in which the locations occupied by stimuli are selected for further processing. Recent research, however, has demonstrated the importance of objects in organizing (or segregating) visual scenes and guiding attentional selection. Because of the long history of spatial (...) attention research, theories of spatial attention are more mature than theories of other visual processes, such as object segregation and object attention. In the present paper, I outline a biased competition account of object segregation and attention, following similar accounts that have been developed for spatial attention (Desimone and Duncan, 1995). In my biased competition account, I seek to understand how some objects can be segregated and selected over other objects in a complex visual scene. Under this account, there are two sources of visual information that allow an object to be processed over other objects: bottom-up information carried by the physical stimulus and top-down information based on an observer's goals. I use the biased competition account to combine many diverse findings from the object segregation and attention literatures into a common framework. (shrink)

Posterior parietal cortex has traditionally been considered to be a sensory association area in which higher-order processing and intermodal integration of incoming sensory information occurs. In this paper, evidence from clinical reports and from lesion and behavioral-electrophysiological experiments using monkeys is reviewed and discussed in relation to the overall functional organization of posterior parietal association cortex, and particularly with respect to a proposed posterior parietal mechanism concerned with the initiation and control of certain classes of eye and limb movements. Preliminary (...) data from studies of the effects of posterior parietal lesions on oculomotor control in monkeys are reported.The behavioral effects of lesions of posterior parietal cortex in monkeys have been found to be similar to those which follow analogous damage of the minor hemisphere in humans, while behavioral-electrophysiological experiments have disclosed classes of neurons in this area which have functional properties closely related to the behavioral acts that are disrupted by lesions of the area. On the basis of current data from these areas of study, it is proposed that the sensory association model of posterior parietal function is inadequate to account for the complexities of the present evidence. Instead, it now appears that many diverse neural mechanisms are locatedin partin parietal cortex, that some of these mechanisms are involved in sensory processing and perceptual functions, but that others participate in motor control, and that still others are involved in attentional, motivational, or emotional processes. It is further proposed that the elementary units of these various neural mechanisms are distributed within posterior parietal cortex according to the columnar hypothesis of Mountcastle. (shrink)

Bird songs often display musical acoustic features such as tonal pitch selection, rhythmicity, and melodic contouring. We investigated higher-order musical temporal structure in bird song using an experimental method called “music scrambling” with human subjects. Recorded songs from a phylogenetically diverse group of 20 avian taxa were split into constituent elements and recombined in original and random order. Human subjects were asked to evaluate which version sounded more “musical” on a per-species basis. Species identity and stimulus treatment were concealed from (...) subjects, and stimulus presentation order was randomized within and between taxa. Two recordings of human music were included as a control for attentiveness. Participants varied in their assessments of individual species musicality, but overall they were significantly more likely to rate bird songs with original temporal sequence as more musical than those with randomized temporal sequence. We discuss alternative hypotheses for the origins of avian musicality, including honest signaling, perceptual bias, and arbitrary aesthetic coevolution. (shrink)

Henry Wellman and colleagues have provided evidence of a robust developmental progression in theory-of-mind (or as we will say, “mindreading”) abilities, using verbal tasks. Understanding diverse desires is said to be easier than understanding diverse beliefs, which is easier than understanding that lack of perceptual access issues in ignorance, which is easier than understanding false belief, which is easier than understanding that people can hide their true emotions. These findings present a challenge to nativists about mindreading, and are said (...) to support a social-constructivist account of mindreading development instead. This article takes up the challenge on behalf of nativism. Our goal is to show that the mindreading-scale findings fail to support constructivism because well-motivated alternative hypotheses have not yet been controlled for and ruled out. These have to do with the pragmatic demands of verbal tasks. (shrink)
