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.

A common view in both philosophy and the vision sciences is that, in human vision, wavelength information is primarily ‘for’ colouring: for seeing surfaces and various media as having colours. In this article we examine this assumption of ‘colour-for-colouring’. To motivate the need for an alternative theory, we begin with three major puzzles from neurophysiology, puzzles that are not explained by the standard theory. We then ask about the role of wavelength information in vision writ large. How might wavelength information (...) be used by any monochromat or dichromat and, finally, by a trichromatic primate with object vision? We suggest that there is no single ‘advantage’ to trichromaticity but a multiplicity, only one of which is the ability to see surfaces and so on as having categorical colours. Instead, the human trichromatic retina exemplifies a scheme for a general encoding of wavelength information given the constraints imposed by high spatial resolution object vision. Chromatic vision, like its partner, luminance vision, is primarily for seeing. Viewed this way, the ‘puzzles’ presented at the outset make perfect sense. 1 Reframing the Problem1.1 Introduction1.2 Three puzzles1.2.1 Why is trichromatic vision an anomaly in diurnal mammals?1.2.2 Why does the colour system occupy such a large and central part in human vision?1.2.3 Why are the blue cones so rare?1.3 Recasting the question2 The Costs and Benefits of Spectral Vision2.1 Spectral information and object vision2.2 Encoding the spectral dimension of light2.2.1 ‘General’ versus ‘specific’ encoding2.2.2 Spectral encoding and the monochromat2.2.3 Spectral encoding and the dichromat2.2.4 Spectral encoding and the human trichromat2.3 Three puzzles revisited2.3.1 Why is trichromatic vision an anomaly in diurnal mammals?2.3.2 Why does the colour system occupy such a large and central part in human vision?2.3.3 Why are the blue cones so rare3 Conclusion.

In Consciousness Explained, Daniel Dennett presents the Multiple Drafts Theory of consciousness, a very brief, largely empirical theory of brain function. From these premises, he draws a number of quite radical conclusions—for example, the conclusion that conscious events have no determinate time of occurrence. The problem, as many readers have pointed out, is that there is little discernible route from the empirical premises to the philosophical conclusions. In this article, I try to reconstruct Dennett's argument, providing both the philosophical views (...) behind the empirical premises, and the hidden empirical arguments behind the derivation of the philosophical conclusions.

Throughout the text, fundamental questions concerning the nature of visual perception are addressed.

Nativists about syntactic processing have argued that linguisticprocessing, understood as the implementation of a rule-basedcomputational architecture, is spared in Williams syndrome, (WMS)subjects – and hence that it provides evidence for a geneticallyspecified language module. This argument is bolstered by treatingSpecific Language Impairments (SLI) and WMS as a developmental doubledissociation which identifies a syntax module. Neuroconstructivists haveargued that the cognitive deficits of a developmental disorder cannot beadequately distinguished using the standard gross behavioural tests ofneuropsychology and that the linguistic abilities of the (...) WMS subject canbe equally well explained by a constructivist strategy of neurallearning in the individual, with linguisitic functions implemented in anassociationist architecture. The neuroconstructivist interpretation ofWMS undermines the hypothesis of a double dissociation between SLI andWMS, leaving unresolved the question of nativism about syntax. Theapparent linguistic virtuosity of WMS subjects is an artefact ofenhanced phonological processing, a fact which is easier to demonstratevia the associationist computational model embraced byneuroconstructivism.

This volume provides an up to date and comprehensive overview of the philosophy and neuroscience movement, which applies the methods of neuroscience to traditional philosophical problems and uses philosophical methods to illuminate issues in neuroscience. At the heart of the movement is the conviction that basic questions about human cognition, many of which have been studied for millennia, can be answered only by a philosophically sophisticated grasp of neuroscience's insights into the processing of information by the human brain. Essays in (...) this volume are clustered around five major themes: data and theory in neuroscience; neural representation and computation; visuomotor transformations; color vision; and consciousness.

Over 35 years ago, Meltzoff and Moore (1977) published their famous article ‘Imitation of facial and manual gestures by human neonates’. Their central conclusion, that neonates can imitate, was and continues to be controversial. Here we focus on an often neglected aspect of this debate, namely on neonatal spontaneous behaviors themselves. We present a case study of a paradigmatic orofacial ‘gesture’, namely tongue protrusion and retraction (TP/R). Against the background of new research on mammalian aerodigestive development, we ask: How does (...) the human aerodigestive system develop and what role does TP/R play in the neonate’s emerging system of aerodigestion? We show that mammalian aerodigestion develops in two phases: (1) from the onset of isolated orofacial movements in utero to the post-natal mastery of suckling at 4 months after birth, and; (2) thereafter, from preparation to the mastery of mastication and deglutition of solid foods. Like other orofacial stereotypies, TP/R emerges in the first phase and vanishes prior to the second. Based upon recent advances in activity-driven early neural development, we suggest a sequence of three developmental events in which TP/R might participate: the acquisition of tongue control, the integration of the central pattern generator for TP/R with other aerodigestive CPGs, and the formation of connections within the cortical maps of S1 and M1. If correct, orofacial stereotypies are crucial to the maturation of aerodigestion in the neonatal period but also unlikely to co-occur with imitative behavior. (shrink)

In our target article, we argued that the positive results of neonatal imitation are likely to be by-products of normal aerodigestive development. Our hypothesis elicited various responses on the role of social interaction in infancy, the methodological issues about imitation experiments, and the relation between the aerodigestive theory and the development of speech. Here we respond to the commentaries.

Researchers have long suspected that grapheme-color synaesthesia is useful, but research on its utility has so far focused primarily on episodic memory and perceptual discrimination. Here we ask whether it can be harnessed during rule-based Category learning. Participants learned through trial and error to classify grapheme pairs that were organized into categories on the basis of their associated synaesthetic colors. The performance of synaesthetes was similar to non-synaesthetes viewing graphemes that were physically colored in the same way. Specifically, synaesthetes learned (...) to categorize stimuli effectively, they were able to transfer this learning to novel stimuli, and they falsely recognized grapheme-pair foils, all like non-synaesthetes viewing colored graphemes. These findings demonstrate that synaesthesia can be exploited when learning the kind of material taught in many classroom settings. (shrink)

In Canions be Causes, David Johnson defends the view that abstractions can have causal force. He offers as his own example of natural kinds ecological niches, arguing that the causal force of these niches in nature is akin to the force of Aristotelian final causes. He concludes that, rooted as it is in seventeenth century mechanism, the currently-accepted model of causality which recognises only efficient causes is inadequate to the needs of contemporary science. In Natural Kinds and Ecological Niches — (...) Response to Johnson ''s Paper, Melinda Hogan offers a critique of Johnson ''s paper which, by begging the question in favor of the very sort of causality Johnson seeks to supplement, misses the epistemological implications of his idea. In this paper I will attempt to clarify and defend Johnson ''s position, pointing out some of its implications for the epistemology of science in general. (shrink)

Ironies are implicit in the title of Zoltan Somhegyi’s book Reviewing the Past: The Presence of Ruins, and this is in keeping with ruins’ own paradoxical character as manifesting endurance and fragility, presence and absence, vivid physicality and an import that is almost entirely reflective. By inviting readers to take a desultory approach to the sequence of the book’s chapters, the author positions them to be active co-explorers of ruins who are reflective about their responses. Somhegyi analyzes various threats to (...) the survival of ruins as structures and aesthetic objects but nevertheless finds bases for some optimism. He ends the book with a chapter on a topic that seems far afield from ruins: museums that make the process of remembering thematic. This somewhat abrupt conclusion forces the reader to draw connections between his remarks on such museums and the topic of ruins. This provocation of the reader’s own reflections encourages a stance akin to that involved in the aesthetic appreciation of ruins and draws attention to their open-endedness. (shrink)

One model for creating artificial consciousness is replicating every fine detail of the brain on computers and setting the model in motion. Consciousness has been experimentally demonstrated to be a much more fragmented experience than we think it to be, perhaps we only need snippets of ourselves to feel conscious. Perhaps consciousness is nothing less and nothing more than story, and all we need do to continue to feel conscious is maintain identity through computer‐based narrative. Applied nanotechnology has generated uncountable (...) applications in electronics, pharmacology, and materials engineering. The best approach to life extension and consciousness expansion might lie in our own marvelously complex and entire bodies, meshed with and augmented by tiny bionan machines that become a part of us, rather than the opposite vision of humans migrating into a machine substrate.

This book explores how shamanic Daoist practices help cultivate the skills of an elicitive peaceworker. Author Kathleen McGoey uses embodied writing to describe her direct experiences with qigong and other meditation forms, and to explain the creation of inner peace that ultimately extends far beyond the individual. A trans-rational understanding of peace weaves together transpersonal interpretations of intuition with ancient Daoist wisdom. By relating the outcomes of such approaches to real world conflict transformation, McGoey proposes a practical personal consciousness (...) that strives for harmony with our's and others' environments.

One of the reasons for the disappearance of beauty in the artistic ideology of the late twentieth century has been the seeming similarity of beauty to certain kinds of kitsch. Beauty has also been associated with flawlessness and with glamour. I will content that the flawless and the glamorous are actually categories of kitsch, and that the dominance of these images in marketing has contributed to our societal tendency to confuse them with beauty. The quests for flawlessness and glamour are (...) both self-sabotaging, a premise on which the marketing of beauty depends. These false paradigms of beauty have ob cured the fact that human beauty manifests an ideal of balance and health that is neither self-conscious nor a consequence of deliberate effort. I will defend the relevance of this ideal to beauty to our personal and cultural well-being. (shrink)

This paper aims at presenting a horizontal approach to the design of communication for joint action in human-robot interaction. According to this approach, social robotics must focus on different parameters of the whole joint action including context, the embedded situation and human psychological profile during the design and test process. Such an approach aims at complementing the standard building-block model that represents the state-of-the-art in robotic communication. Moreover, we provide some general ideas of how the model can facilitate the use (...) of available communicative strategies for creating more efficient culturally sustainable robots in contexts of joint action.
