Researchers from the 1940's through the present have found that normal, sighted people can echolocate - that is, detect properties of silent objects by attending to sound reflected from them. We argue that echolocation is a normal part of our conscious, perceptual experience. Despite this, we argue that people are often grossly mistaken about their experience of echolocation. If so, echolocation provides a counterexample to the view that we cannot be seriously mistaken about our own current conscious (...) experience. (shrink)

Philosophers have recently argued that since there are people who are blind, but don't know it, and people who echolocate, but don't know it, conscious introspection is highly unreliable. I contend that a second look at Anton's syndrome, human echolocation, and ‘facial vision’ suggests otherwise. These examples do not support skepticism about the reliability of introspection.

Assistive Device Art derives from the integration of Assistive Technology and Art, involving the mediation of sensorimotor functions and perception from both, psychophysical methods and conceptual mechanics of sensory embodiment. This paper describes the concept of ADA and its origins by observing the phenomena that surround the aesthetics of prosthesis-related art. It also analyzes one case study, the Echolocation Headphones, relating its provenience and performance to this new conceptual and psychophysical approach of tool design. This ADA tool is designed (...) to aid human echolocation. They facilitate the experience of sonic vision, as a way of reflecting and learning about the construct of our spatial perception. Echolocation Headphones are a pair of opaque goggles which disable the participant’s vision. This device emits a focused sound beam which activates the space with directional acoustic reflection, giving the user the ability to navigate and perceive space through audition. The directional properties of parametric sound provide the participant a focal echo, similar to the focal point of vision. This study analyzes the effectiveness of this wearable sensory extension for aiding auditory spatial location in three experiments; optimal sound type and distance for object location, perceptual resolution by just noticeable difference, and goal-directed spatial navigation for open pathway detection, all conducted at the Virtual Reality Lab of the University of Tsukuba, Japan. The Echolocation Headphones have been designed for a diverse participant base. They have both the potential to aid auditory spatial perception for the visually impaired and to train sighted individuals in gaining human echolocation abilities. Furthermore, this Assistive Device artwork instigates participants to contemplate on the plasticity of their sensorimotor architecture. (shrink)

Why do humpback whales sing? This paper considers the hypothesis that humpback whales may use song for long range sonar. Given the vocal and social behavior of humpback whales, in several cases it is not apparent how they monitor the movements of distant whales or prey concentrations. Unless distant animals produce sounds, humpback whales are unlikely to be aware of their presence or actions. Some field observations are strongly suggestive of the use of song as sonar. Humpback whales sometimes stop (...) singing and then rapidly approach distant whales in cases where sound production by those whales is not apparent, and singers sometimes alternately sing and swim while attempting to intercept another whale that is swimming evasively. In the evolutionary development of modern cetaceans, perceptual mechanisms have shifted from reliance on visual scanning to the active generation and monitoring of echoes. It is hypothesized that as the size and distance of relevant events increased, humpback whales developed adaptive specializations for long-distance echolocation. Differences between use of songs by humpback whales and use of sonar by other echolocating species are discussed, as are similarities between bat echolocation and singing by humpback whales. Singing humpback whales are known to emit sounds intense enough to generate echoes at long ranges, and to flexibly control the timing and qualities of produced sounds. The major problem for the hypothesis is the lack of recordings of echoes from other whales arriving at singers immediately before they initiate actions related to those whales. An earlier model of echoic processing by singing humpback whales is here revised to incorporate recent discoveries. According to the revised model, both direct echoes from targets and modulations in song-generated reverberation can provide singers with information that can help them make decisions about future actions related to mating, traveling, and foraging. The model identifies acoustic and structural features produced by singing humpback whales that may facilitate a singer’s ability to interpret changes in echoic scenes and suggests that interactive signal coordination by singing whales may help them to avoid mutual interference. Specific, testable predictions of the model are presented. (shrink)

What does it feel like to be a bat? Is conscious experience of echolocation closer to that of vision or audition? Or do bats process echolocation nonconsciously, such that they do not feel anything about echolocation? This famous question of bats' experience, posed by a philosopher Thomas Nagel in 1974, clarifies the difficult nature of the mind–body problem. Why a particular sense, such as vision, has to feel like vision, but not like audition, is totally puzzling. This (...) is especially so given that any conscious experience is supported by neuronal activity. Activity of a single neuron appears fairly uniform across modalities and even similar to those for non-conscious processing. Without any explanation on why a particular sense has to feel the way it does, researchers cannot approach the question of the bats' experience. Is there any theory that gives us a hope for such explanation? Currently, probably none, except for one. Integrated information theory has potential to offer a plausible explanation. IIT essentially claims that any system that is composed of causally interacting mechanisms can have conscious experience. And precisely how the system feels is determined by the way the mechanisms influence each other in a holistic way. In this article, I will give a brief explanation of the essence of IIT. Further, I will briefly provide a potential scientific pathway to approach bats' conscious experience and its philosophical implications. If IIT, or its improved or related versions, is validated enough, the theory will gain credibility. When it matures enough, predictions from the theory, including nature of bats' experience, will have to be accepted. I argue that a seemingly impossible question about bats' consciousness will drive empirical and theoretical consciousness research to make big breakthroughs, in a similar way as an impossible question about the age of the universe has driven modern cosmology.

Many philosophers have held that we cannot say what it is like to be a bat as they present a fundamentally alien form of life. Another view held by some philosophers, bat scientists, and even many laypersons is that echolocation is, somehow, at least in part, a kind of visual experience. Either way, bat echolocation is taken to be something very mysterious and exotic. I utilize empirical and intuitive considerations to support an alternative view making a much more (...) mundane contention about bat phenomenology: echolocatory experience probably just has an auditory character. These points also call for further reflection on our intuitions about animal consciousness and standard arguments for the explanatory gap. (shrink)

RÉSUMÉLes qualia n'existent pas. La différence phénoménologique entre voir et imaginer, c'est que les propositions auxquelles l'expérient commence à croire dans le premier cas sont uniquement considérées dans le second. Nous pouvons savoir «quel effet cela fait d’être une chauve-souris» en sachant que leur faculté d’écholocation les informe non-inférentiellement des formes, grandeurs, et distances directionnelles des surfaces à proximité. Toutefois, les termes désignant les qualités secondes (comme les couleurs) sont les noms des propriétés-types qu'ils désignent, et dérivent causalement d'un «baptême» (...) verbal; les expérients ne peuvent donc connaître le caractère des expériences de couleur sans étudier la physiologie du cerveau.

This paper assesses five main empirical scientific arguments against the reliability of belief formation on the basis of introspecting phenomenal states. After defining ‘reliability’ and ‘introspection’, I discuss five arguments to the effect that phenomenal states are more elusive than we usually think: the argument on the basis of differences in introspective reports from differences in introspective measurements; the argument from differences in reports about whether or not dreams come in colours; the argument from the absence of a correlation between (...) visual imagery ability and the performance on certain cognitive tasks; the argument from our unawareness of our capacity of echolocation; the argument from inattentional blindness and change blindness. I argue that the experiments on which these arguments are based do not concern belief formation on the basis of introspection in the first place or fail to show that it is unreliable, even when limited to introspection of phenomenal states.

Evolutionary psychology—in its ambitious version well formulated by Cosmides and Tooby (e.g., Cosmides & Tooby 1987, Tooby & Cosmides 1992) —will succeed to the extent that it causes cognitive psychologists to rethink central aspects of human cognition in an evolutionary perspective, to the extent, that is, that psychology in general becomes evolutionary. The human species is exceptional by its massive investment in cognition, and in forms of cognitive activity—language, metarepresentation, abstract thinking—that are as unique to humans as echolocation is (...) unique to bats. The promise of evolutionary psychology is thus to help explain not just traits of human psychology that are homologous to those of many other species, but also traits of human psychology that are genuinely exceptional and that in turn help explain the exceptional character of human culture and ecology. However, most of the work done in evolutionary psychology so far is on aspects of human psychology that are not specifically human except in their details. Showing, for instance, how human preferences in mate choice are fine -tuned in the way the theory of evolution would predict is of great interest (see e.g., Buss 1994) but it can be done on the basis of a relatively shallow psychology. This makes work on distinctly human adaptations involving higher cognition of particular importance for defenders of a psychologically ambitious evolutionary psychology. What is often presented (e.g., Pinker, 1997) as the signal achievement of cognitive evolutionary psychology in this respect is the experimental testing of Cosmides’ (1989) hypothesis that there exists an evolved competence to deal with social contracts, and, in particular to detect cheaters. We want to argue that, because of faulty methodological choices—the quasi-exclusive reliance on the four-cards selection task—, the hypothesis has in fact not yet been tested. The plan of this chapter is as follows: We begin, with a short presentation of Cosmides’s social contract hypothesis, of Wason selection task, and of Cosmides’s reasons to use the task in order to test the theory..

Knowing the subjective perspective of other agents, how the world manifests itself to them, through the prism of their specific embodiment and situated, remains beyond the limits of our direct cognition and sometimes even imagination. Simulations using virtual reality technology (VR) can partially bring us closer to the embodied perspective of other agents. This technology enables the experience of another body, as one’s own and causal, during the phenomenon of virtual embodiment. The user can be situated in a simulated environment (...) specific to the agent and experience it through the prism of modified sensory modalities (e.g., using the sense of echolocation in the case of a bat). However, the possibilities of simulation are significantly limited by technological and biological factors. The purposes of this text are to review currently developed simulations of being another agent and to analyze the potential of VR technology to experience the embodied perspective of other agents as one’s own.

Here is one way that philosophers and biologists sometimes speak of Darwin’s explanatory innovation: ‘Eyes, organs of echolocation, camouflage and the like are all wonderful instances of contrivance, of complex adaptation, of good design. Paley and the other natural theologians sought to explain this good design by appeal to an intelligent designer. Darwin, on the other hand, offers us a superior explanation for the appearance of this same property: Darwin shows us that we can explain good design through the (...) action of selection. Indeed, selection is the only process that can explain good design in nature. And that is why evolutionary biologists can continue to use a version of the argument from design called the argument from biological design: when we see an instance of good design in nature, we should infer not the guiding hand of God, but the hand of selection at work.’ -/- .

Sensory substitution devices are a type of sensory prosthesis that (typically) convert visual stimuli transduced by a camera into tactile or auditory stimulation. They are designed to be used by people with impaired vision so that they can recover some of the functions normally subserved by vision. In this chapter we will consider what philosophers might learn about the nature of the senses from the neuroscience of sensory substitution. We will show how sensory substitution devices work by exploiting the cross-modal (...) plasticity of sensory cortex: the ability of sensory cortex to pick up some types of information about the external environment irrespective of the nature of the sensory inputs it is processing. We explore the implications of cross-modal plasticity for theories of the senses that attempt to make distinctions between the senses on the basis of neurobiology. (shrink)

Macphail’s comparative approach to intelligence focused on associative processes, an orientation inconsistent with more multifaceted lay and scientific understandings of the term. His ultimate emphasis on associative processes indicated few differences in intelligence among vertebrates. We explore options more attuned to common definitions by considering intelligence in terms of richness of representations of the world, the interconnectivity of those representations, the ability to flexibly change those connections, knowledge, and individual differences. We focus on marine mammals, represented by the amphibious pinnipeds (...) and the aquatic cetaceans and sirenians, as animals that transitioned from a terrestrial existence to an aquatic one, experiencing major changes in ecological pressures. They adapted with morphological transformations related to streamlining the body, physiological changes in respiration and thermoregulation, and sensory/perceptual changes, including echolocation capabilities and diminished olfaction in many cetaceans, both in-air and underwater visual focus, and enhanced senses of touch in pinnipeds and sirenians. Having a terrestrial foundation on which aquatic capacities were overlaid likely affected their cognitive abilities. Vocal and behavioral observational learning capabilities in the wild and in laboratory experiments suggest versatility in group coordination. Empirical reports on aspects of intelligent behavior like problem-solving, spatial learning, and concept learning by various species of cetaceans and pinnipeds, suggest rich cognitive abilities. The high energy demands of the brain suggest brain-intelligence relationships might be fruitful areas for the study when specific hypotheses are considered, e.g., brain mapping indicates hypertrophy of specific sensory areas in marine mammals. Modern neuroimaging techniques provide ways to study neural connectivity, and the patterns of connections between sensory, motor, and other cortical regions provide a biological framework for exploring how animals represent and flexibly use information in navigating and learning about their environment. At this stage of marine mammal research, it would still be prudent to follow Macphail’s caution that it is premature to make strong comparative statements without more empirical evidence, but an approach that includes learning more about how animals flexibly link information across multiple representations could be a productive way of comparing species by allowing them to use their specific strengths within comparative tasks.

I address this talk to anyone who believes in the possibility of an informative empirical science about sensory qualities. Potentially this is a large audience. By "sensory quality" I mean those qualities manifest in various sensory experiences: color, taste, smell, touch, pain, and so on. We should include sensory modalities humans do not share, such as electro-reception in fish, echolocation in bats, or the skylight compass in birds. Those pursuing empirical science about this large domain might pursue it in (...) the halls of experimental psychology, psycho-physics, psychometrics, psycho-physiology, sensory physiology, neuroscience, neuro-biology, comparative psychology, neuro-anatomy, and so on and on. These days even molecular genetics has kicked in with some notable recent contributions to the sequencing of genes for photopigments and for olfactory receptors. But to all those investigators in all those halls I bring bad news. Your discipline is _a priori_ impossible. Philosophers whom you do not know have uncovered _a priori_ proofs that empirical investigation which proceeds along the lines currently underway, or which will proceed along lines that are currently _imaginable_, does not, will not, and cannot explain the sensory qualities of experience. Or at least so they say. You might as well give up now. (shrink)

It is a truism among ethologists that one must not forget that animals perceive and represent the world differently from humans. Sometimes this caution is phrased in terms of von Uexküll’s Umwelt concept. Yet it seems possible (perhaps even unavoidable) to adopt a common ontological framework when comparing different species of mind. For some purposes it seems sufficient to ­anchor comparative cognition in common-sense categories; bats echolocate insects (or a subset of them) after all. But for other purposes it seems (...) necessary to find out more about how organisms organize their perceptions into biologically significant and perhaps cognitively meaningful states. Complex animals have high bandwidth sensory channels that feed into large nerve networks with very complex dynamics. Even for relatively simple animals belonging to species believed to have a small, fixed number of neurons, the odds are very much against any two animals of the same species, let alone different species, having exactly the same couplings to the environment, the same dimensionality in their nervous systems, or the same dynamics. Given such diversity (which von Uexküll himself recognized), how should we think about shared representation, shared meaning, and cognitive similarity between individuals and species? (shrink)

The effort to understand speech perception on the basis of relationships between acoustic parameters of speech sounds is to be recommended. Neural specializations (combination-sensitivity) for echolocation, communication, and sound localization probably constitute the common mechanisms of vertebrate auditory processing and may be essential for speech production as well as perception. There is, however, no need for meaningful maps.

The locus equation proposal ignores a fundamental difference between human speech perception and nonhuman echolocation and sound localization, offers a questionable account of the function of consonant-vowel coarticulation, and is further undermined if the effects of other forms of coarticulation are considered. The function of coarticulation is to convey phonetic information rapidly and reliably.

Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed (...) and implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

Humans and other animals perceive with many different sensory modalities, includ- ing olfaction, touch, audition, vision, echolocation, proprioception, gustation, and some other senses, depending on different criteria and definitions.

Section 1.2 discusses the information-processing approach and hierarchical explanations, while section 1.3 looks into the historical development of philosophical studies of perception.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Specter of Speciesism: Buddhist and Christian Views of AnimalsChristopher Key ChappleThe Specter of Speciesism: Buddhist and Christian Views of Animals. By Paul Waldau. Oxford and New York: Oxford University Press, 2002. xv + 303 pp.At the Parliament of World Religions held in Cape Town in 1999, Dada Vaswani, a leading spiritual voice within India, proclaimed that the nineteenth century brought the liberation of slaves, that the twentieth (...) century brought the liberation of women, and that the twenty-first century will bring the liberation of animals. For Paul Waldau, a key piece in this transformation will result from the insights of ethology, the specialized branch of biology that offers new information regarding the consciousness of animals. Scientific research has revealed that animals occupy a complex world, replete with desires and emotions. Based on this scientific research, Waldau asserts that a new morality will arise that acknowledges the inherent moral standing of animals, and will overturn the long-held view that animals serve only one purpose: to serve humanity. Otherwise, he asserts, humans will remain enmeshed in the tyranny of speciesism.In this meticulous study, Paul Waldau assesses the origins of the term "speciesism," coined by Ryder in 1970. He explores the link between speciesism and slavery, colonization, and the oppression of women and children. Just as ethical discourse has been altered through history regarding these issues, Waldau suggests that as more information becomes available, human attitudes regarding animals will evolve. However, due to entrenched religious views, this change will be gradual. This book consists of a sustained argument for expanding our categories of worth beyond purely anthropocentric values. Waldau suggests that although humans hold a power advantage over animals, "[d]ifferences in abilities, and even hierarchy, to the extent they exist, do not automatically imply the propriety of dominance, let alone tyranny" (p.39).To develop his argument, Waldau writes about three higher-order mammals that merit consideration: the great apes, elephants, and cetaceans (whales and dolphins). Each of these groups of animals display complex abilities and have, in proportion to the size of their bodies, large brains. Genetically, chimpanzees and humans share 98.4% identical DNA. Chimpanzees can develop high language functioning and use [End Page 293] tools, subverting the assumptions that these two capabilities are uniquely human. In regard to elephants, Waldau writes that "[b]oth Aristotle and Pliny designated elephants as the animals closest to humans in intelligence" (p. 79). He particularly notes their highly developed matriarchal social structure and their ability to communicate over long distances. Similarly, Waldau summarizes recent research on cetaceans' ability to protect one another through echolocation and a highly intricate communication system based on touch and soundings. Because of this scientific resarch, Waldau asserts that Descartes was wrong to proclaim that "dumb animals do not think" (p. 89).Waldau's underlying argument asks that humans not "lump" all animals together under one umbrella category, but assess each group of animals according to its own gifts. He asks that we not regard humans as utterly unique (and hence better), but pay attention to current scientific research and ethical insights that value animals for their inherent worth. Though Waldau does not attempt to establish a new hierarchy of more-valued creatures, he does argue persuasively that great apes, elephants, and the cetaceans deserve greater respect, and that we need to re-examine and hopefully deconstruct the inherited cultural understanding of all animals as simply "other."This brings us to the primary focus of the book: an investigation of the place of animals in Buddhist and Christian traditions. In Buddhism, animals suffer their fate because of negative karma, and, at best, can hope to be reborn as a human being capable of receiving the Buddha's teachings. Waldau cites various texts, from the Jataka tales to the Mahayana sutras, that accord conscience and agency to specific animals. He claims, however, that Buddhist cultures have generally not gone out of their way to cultivate a culture of animal benevolence, citing the example of elephant trainers in Southeast Asia. Some mention of the Buddhist practice of purchasing and releasing animals, widely practiced in East Asia, would have been helpful. Unlike some authors, Waldau... (shrink)

A glance at the contents of this book might be enough to persuade that it is absolutely required reading for anyone interested in the study of consciousness. The discussion is replete with insight into a number of neglected topics: colour in dream experience (chapter 1), echolocation in auditory experience (chapter 4) and closed-eye visualisations (chapter 8). More familiar themes such as the spatial qualities presented in visual experience (chapter 2), visual imagery (chapter 3), the introspectionist movement (chapter 5), conscious (...) attention and multisensory experience (chapter 6) are given genuinely novel treatment. Chapter 7, titled ‘The Unreliability of Introspection’ is almost a microcosm of the book as a whole; it is not quite representative of the entire book but it gives a strong flavour of the style of argument employed elsewhere, so the half-interested (or hurried) reader would be well advised to take it in as a taster.

In “What is it like to be boring and myopic?” Kathleen Akins offers an interesting, empirically driven, argument for thinking that there is nothing that it is like to be a bat. She suggests that bats are “boring” in the sense that they are governed by behavioral scripts and simple, non-representational, control loops, and are best characterized as biological automatons. Her approach has been well received by philosophers sympathetic to empirically informed philosophy of mind. But, despite its influence, her work (...) has not met with any critical appraisal. -/- It is argued that a reconsideration of the empirical results shows that bats are not boring automatons, driven by short input-output loops, instincts, and reflexes. Grounds are provided for thinking that bats satisfy a range of philosophically and scientifically interesting elaborations of the general idea that consciousness is best understood in terms of representational functions. A more complete examination of bat sensory capabilities suggests there is something that it is like after all. -/- The discussion of bats is also used to develop an objection to strongly neurophilosophical approaches to animal consciousness.
