Do AI programs just make it quicker and easier for humans to do what they can do already, or can the range of do-able things be extended? This paper suggests that cognitively-oriented technology can make it possible for humans to construct and carry out mental operations, which were previously impossible. Probable constraints upon possible human mental operations are identified and the impact of cognitive technology upon them is evaluated. It is argued that information technology functions as a cognitive prosthetic enhancing (...) human intelligence and planning capabilities. Boundaries and constraints which Kant, Whorf, and many post-modernist theorists have seen as intrinsic to human cognition now cease to apply. (shrink)

This paper holds an evolutionary approach to musical semantics. Revolving around the nature/nurture dichotomy, it considers the role of the dispositional machinery to respond to sounding stimuli. Conceiving of music as organized sound, it stresses the dynamic tension between music as a collection of vibrational events and their potential of being structured. This structuring, however, is not gratuitous. It depends on levels of processing that rely on evolutionary older levels of reacting to the sounds as well as higher-level functions of (...) the brain, which allow listeners to emancipate themselves from mere acoustic processing of sounds to the level of epistemic interactions with the sounding music. These interactions are partly autonomous and partly constrained, but they all stress the realization of systemic cognition in the context of a living system‘s interactions with the environment. As such, listeners can be conceived as adaptive devices, which can build up new semiotic linkages with the sounding world. (shrink)

The present paper proposes a definition for the complex polysemic concepts of consciousness and awareness (in humans as well as in other species), and puts forward the idea of a progressive ontological development of consciousness from a state of ‘childhood’ awareness, in order to explain that humans are not only able to manipulate objects, but also their mental representations. The paper builds on the idea of qualia intended as entities posing regular invariant requests to neural processes, trough the permanence of (...) different properties. The concept of semantic differential introduces the properties of metaphorical qualia as an exclusively human ability. Furthermore this paper proposes a classification of qualia, according to the models–with different levels of abstraction–they are implied in, in a taxonomic perspective. This, in turn, becomes a source of categorization of divergent representations, sign systems, and forms of intentionality, relying always on biological criteria. New emerging image-of-the-world-devices are proposed, whose qualia are likely to be only accessible to humans: emotional qualia, where emotion accounts for the invariant and dominant property; and the qualic self where continuity, combined with the oneness of the self, accounts for the invariant and dominant property. The concept of congruence between different domains in a metaphor introduces the possibility of a general evaluation of truth and falsity of all kinds of metaphorical constructs, while the work of Matte Blanco enables us to classify conscious versus unconscious metaphors, both in individuals and in social organizations.

The dominant position in the field of artificial intelligence (AI) is computationalism where the operative principle is that cognition in general and consciousness in particular can be captured by identification of the proper set of computations. This position has been attacked from several angles, most effectively, in my opinion, by John Searle in his now famous Chinese Room thought experiment. I critique this Searlean perspective on the grounds that, while it is probably correct in its essentials, it does not go (...) far enough. Quite simply, it runs afoul of the problem of emergentism. The proffered solution to this problem is that consciousness (or very rudimentary forms of it) needs to be viewed as an inherent property of organic form. While this recasting of the problem solves the emergentist dilemma it opens up a number of other issues. However, the new problems, unlike the old, appear in principle to be amenable to scientific analysis. (shrink)

This essay is about the ensuing problem that in general it is nothelpful to talk about non-standard knowledge practices as modeled after our Western ideas of what knowledge is. It negotiates this problem by arguing that artisanal knowledge is an independent and self-contained mode of knowledge and is arranged in three parts. In the first part an outline is given of the key assumptions of the interactionist conception of knowledge that needs to be put in place as an alternative to (...) the basically Kantian mixture of empiricist and rationalist assumptions of the folk model of Western academic thinking about knowledge. In this interactionist conception of knowledgeartisanal knowledge gets center stage. In the second part, the notion of craftknowledge is opened up as much as possible. The third and final part takes upthe question whether craft knowledge is a cultural universal. (shrink)

Fodor has argued that observation is theory neutral, since the perceptual systems are modular, that is, they are domain‐specific, encapsulated, mandatory, fast, hard‐wired in the organism, and have a fixed neural architecture. Churchland attacks the theoretical neutrality of observation on the grounds that (a) the abundant top‐down pathways in the brain suggest the cognitive penetration of perception and (b) perceptual learning can change in the wiring of the perceptual systems. In this paper I introduce a distinction between sensation, perception, and (...) observation and I argue that although Churchland is right that observation involves top‐down processes, there is also a substantial amount of information in perception which is theory‐neutral. I argue that perceptual learning does not threaten the cognitive impenetrability of perception, and that the neuropsychological research does not provide evidence in favor of the top‐down character of perception. Finally, I discuss the possibility of an off‐line cognitive penetrability of perception. (shrink)

Neurophysiological evidence consonant with F&L's lambda model is reviewed and results of additional experiments are presented. The evidence shows that there are neurons in the motor cortex that respond to selective band widths of passive sinusoidal movements; the additional data show how, with movement, directionally sensitive population vectors can be shown to emerge from the data.

The purpose of the article is to analyze the concept of contextual emergence as well as its selected applications in philosophy of mind and cognitive science. In the first section the author presents the general assumptions of the emergentist model of reality. He stresses that the concept of emergence can be applied to the description of various levels of organization of nature: one of these levels is that of mental-cognitive processes, analyzed within the fields of philosophy of mind and cognitive (...) science. In the subsequent sections, he introduces the definitions of contextual emergence and systemic causation and he points to their selected applications to mentalcognitive systems. In the concluding part, he presents the ideas of Gerald Edelman and Michael Gazzaniga on the role of contextual explanations as well as the concepts of emergence in the philosophy of biology and cognitive neuroscience. He also indicates the possibility of incorporating the concept of contextual emergence into active externalism and the extended cognition theory. (shrink)

According to some philosophers, computational explanation is proprietary
to psychology—it does not belong in neuroscience. But neuroscientists routinely offer computational explanations of cognitive phenomena. In fact, computational explanation was initially imported from computability theory into the science of mind by neuroscientists, who justified this move on neurophysiological grounds. Establishing the legitimacy and importance of computational explanation in neuroscience is one thing; shedding light on it is another. I raise some philosophical questions pertaining to computational explanation and outline some promising answers that (...) are being developed by a number of authors. (shrink)

Abstract Cognitivism, presently the major paradigm of psychology, presents a scientific account of mental life. Buddhism also presents an account of mental life, but one which is integral with its wider ethical and transcendental concerns. The postmodern appraisal of science provides a framework within which these two accounts may be compared without inheriting many of the assumed oppositions between science and religion. It is concluded that cognitivism and Buddhism will have complementary roles in the development of a more pluralist psychological (...) science. In this development it will be necessary to address what values are implicit in science. (shrink)

In this article I briefly assesses Philip Hefner's concept of the created co-creator by considering both what it does and does not claim. Looking at issues of reductionism, biological selfishness, biology and freedom, and environmental ethics, I point out strengths and weaknesses in Hefner's conception of the created co-creator.

Abstract.In order to develop a single narrative of God's continuing creation that includes salvation, this essay in theological construction focuses on the idea of transformation. Using the metaphor of conceptual maps in science and religion, it weaves together ideas about evolution, God working in the world, and how humans can be brought to wholeness in community in relation to God.

. Cognitive science challenges our understandings of self and freedom. In this article, adapted from a chapter in Minding God: Theology and the Cognitive Sciences , I review some of the scientific literature with regard to issues of self and freedom. I argue that our sense of self is a construct and heavily dependent on the kind of brain that we have. Furthermore, understanding the issue of freedom requires an understanding of the findings of cognitive science. Human beings are constrained (...) to be free; our biology in no small way determines the kinds of freedom that we are able to have. (shrink)

Generation of swing phase limb trajectory over obstacles during locomotion should be a reasonable test for the λ model proposed by Feldman and Levin. The observed features such as lack of simple amplitude scaling of endpoint (toe) trajectories for different obstacle heights, complex shaped toe velocity profiles, and exploitation of passive intersegmental dynamics to control limb elevation cannot be adequately explained by the λ model.

The trade-off between force and length of muscle as adjusted by neural signals is a critical fact in the dynamics of motor control. Whether we call it “length-tension effect,” “feedback-like,” “invariant condition,” or “spring-like” is unimportant. We must not let semantics or details of representation obscure the basic physics of effects introduced by this trade-off in muscle.

The paper undertakes to characterize Hao Wang's style, convictions, and method as a philosopher, centering on his most important philosophical work From Mathematics to Philosophy, 1974. The descriptive character of Wang's characteristic method is emphasized. Some specific achievements are discussed: his analyses of the concept of set, his discussion, in connection with setting forth Gödel's views, of minds and machines, and his concept of ‘analytic empiricism’ used to criticize Carnap and Quine. Wang's work as interpreter of Gödel's thought and the (...) importance of his writings as a source are also discussed. (shrink)

The model identifies a spatial coordinate frame within which the sensorimotor apparatus produces movement. Its spatial nature simplifies its coupling with spatial reference frames used concurrently by vision and proprioception. While the positional reference frame addresses the performance of spatial tasks, it seems to have little to say about movements involving energy expenditure as the principle component of the task.

We describe a solution to the redundancy problem related to that proposed in Feldman & Levin's target article. We suggest that the system may use a fixed mapping between commands organized at the level of degrees of freedom and commands to individual muscles. This proposal eliminates the need to maintain an explicit representation of musculoskeletalgeometry in planning movements.

The paper argues that contemporary consciousness studies can profit from Charles S. Peirce’s philosophy of consciousness. It confronts mainstream tendencies in contemporary consciousness studies, including those which consider consciousness as an unsolvable mystery, with Peirce’s phenomenological approach to consciousness. Peirce’s answers to the following contemporary issues are presented: phenomenological consciousness and the qualia, consciousness as self-controlled agency of humans, self-control and self-reflection, consciousness and language, self-consciousness and introspection, consciousness and the other, consciousness of nonhuman animals, and the question of a (...) quasi-consciousness of the physical universe. A detailed account of Peirce’s three modes of consciousness is presented: primisense, qualisense or feeling-consciousness, altersense, and medisense, the consciousness of cognition, thought, and reasoning. In contrast to consciousness studies that establish a rather sharp dividing line between conscious and unconscious states of mind, Peirce adopts the principle of synechism, the theory of continuity. For him, consciousness is a matter of degree. An important difference between Peirce’s concept of qualia and current theories of qualia in human consciousness is discussed. The paper shows how consciousness, according to Peirce, emerges from unconscious qualia and vanishes into equally unconscious habits. It concludes with a study of the roles of qualia, habit, and self-control in Peirce’s theory of signs, in particular in qualisigns and symbols, and the question of signs as quasi-conscious agents in semiosis.

The fact that all languages known are digital poses the question of their origin. The answer developed here treats language as the interface of information theory and molecular development by showing previously unrecognized isomorphisms between the analog and digital features of language and life at the molecular level. Human language is a special case of signal transduction and hence is subject to the coding aspects of Shannon's theorems and the analog aspects of pattern recognition, each represented by genotype and phenotype. (...) Digital language acquisition is late in evolution and postnatal development and requires a neural reorganization by a mechanism of somatic network programming in response to the environment. Such a mechanism would solve the Chomsky conundrum of how children can learn any language without knowing rules of grammar too numerous to be encoded genotypically.

The nature of mystical experience has been hotly debated. Essentialists divide into two camps: 1) immediate identity beyond any subject-object structure 2) the mystical object maintaining some distinctness at the point of contact. Paul Tillich’s mystical a priori has some affinities with the former, while William James’ model of religious experience coheres only with the latter. Opposing the essentialists are constructivists. After noting some ironies of the constructivist position, this article elaborates difficulties with 1) the traditional model of pure identity (...) with the divine by certain mystics, 2) the Tillichian universal mystical awareness, and 3) the Jamesian direct perceptual model. Finally, it proposes that the human body and brain mediate mystical experience, which consists of a distinctive sense of bodily harmony conjoined with openness to the potentialities of an integrated environment, involving distinctive neurological processes.

It is proposed here that the spinal network of proprioceptive feedback from length and force receptors constitutes the mechanism underlying the coordination of activation thresholds for muscles acting about the same and neighboring joints. For the most part, these circuits come between motoneurons and supraspinal signals, invalidating the idea that the activation thresholds constitute control variables for the motor system.

This paper provides a historical overview of cognitive psychology and computational theories in cognitive science. Critiques of the computational model are discussed. The perspective of the evolution of mind and brain provides an alternative model such as that presented by Merlin Donald in terms of the “Hybrid Mind.” This “naturalist” model is also consistent with what we know of cognitive development in childhood. It provides a better understanding of cognition in situated context than the computational alternatives and is a better (...) fit as a model of mind for the social sciences, including for economic decision making.

The field of psychology has emphasized quantitative laboratory research as a defining character of its role as a science, and has generally de-emphasized qualitative research and theorizing throughout its history. This article reviews some of the effects of this emphasis in two areas, intelligence testing, and learning and memory. On one side, quantitative measurement produced the widely used IQ test but shed little light on the construct of intelligence and its role in human cognition. On the other side, reductive quantification (...) and experimental constraints limited the investigation and understanding of human memory systems and complex learning throughout the first century of the field’s history. Recent research under fewer constraints has made greater progress in these areas. (shrink)

The essay deals with the mechanism of interpretation for legal metaphorical expressions. Firstly, it points out the perspective the cognitive approach induced about legal metaphors; then it suggests that this perspective gains in plausibility when a new bilateral model of language understanding is endorsed. A possible sketch of the meaning-making procedure for legal metaphors, compatible with this new model, is then proposed, and illustrated with some examples built on concepts belonging to the Italian Civil Code. The insights the bilateral model (...) of understanding provides are compared with the practice followed by legal communities for dealing with the metaphorical expressions they coin and use.

Generalizing the notion that muscles are positional frames of reference, a high-dimensional muscle space is defined for multi-muscle systems with an embedded low-dimensional motor manifold of functional articulators. A central representation of such a manifold is proposed as computational body schema. The example of the jaw-tongue system is presented, discussing the relation of functional articulators with kinematic invariances and control problems.

¿Cómo se nos presenta, fenomenológicamente la realidad humana? Es la que vemos diariamente en nuestra vida personal y social. Estamos hechos de materia, formamos parte del universo evolutivo. Además, está formada en nosotros una vida psíquica: la sensación, un sistema de percepciones, una conciencia integrada, una condición de sujeto psicológico; producimos conocimiento, emociones, motivaciones; pero, sobre todo, tenemos una mente que discurre racionalmente y nos instala en un mundo de emociones humanas; esta razón emocional está en la base de la (...) búsqueda de la verdad del universo, del sentido de la vida y de la responsabilidad moral, en la vida personal y social. Nuestra realidad humana es, pues, una realidad personal. Somos personas. Ahora bien, ¿cómo explica hoy la ciencia, la neurología, el hecho de que nuestra realidad humana posea estas propiedades que nos hacen personas? Esto debería poder explicarse desde el mundo físico-biológico. Ahora bien, en concreto, ¿cómo la ciencia hace posible explicar que la evolución nos haya producido a nosotros en nuestra condición de personas? Es decir, ¿cuál es el soporte físico que hace inteligible la ontología psico-bio-física que produce evolutivamente nuestra experiencia personal fenomenológica? Esta es, en último término, todavía hoy la cuestión fundamental de las ciencias humanas. Lo que la ciencia, a saber, la neurología, debe explicar es obvio: el hecho de que haya emergido la sensibilidad-conciencia, nuestra condición de sujetos psíquicos, el conocimiento y la razón emocional; de tal manera que, una vez emergida la razón emocional, lleve por sí misma a constituir la actividad racional y las emociones propias de la persona humana encaminada a construir el sentido de su vida. Estas son las cuestiones que abordamos en este artículo. (shrink)

In this paper, the Author reviewed the typical objections against the claim that brains are computers, or, to be more precise, information-processing mechanisms. By showing that practically all the popular objections are based on uncharitable interpretations of the claim, he argues that the claim is likely to be true, relevant to contemporary cognitive science, and non-trivial.

Parameters of the lambda model seem tightly linked to certain characteristics of human performance influenced by weightlessness. This commentary suggests that there is a valuable opportunity to probe the lambda model using the changed environment experienced during space flight. The likely benefits are a better model and a better understanding ofthe consequences of weightlessness for human performance.

Studies in economics and humanities generally have intrinsic problems that this work illustrates, along with innovations for overcoming them. The main limitations and weak-points of orthodox theory necessitate the use in their stead of other multi-disciplinary approaches, like complexity science, agent-based simulations and artificial life simulations. An example of an artificial life simulation applied in the economics field concerning the exchange process shows the benefits of such new conceptual and methodological instruments.

Talia Welsh (2006) argues that Shaun Gallagher and Andrew Meltzoff's (1996) application of neonatal imitation research is insufficient grounds for their claim that neonates are born with a primitive body image and thus an innate self-awareness. Drawing upon an understanding of the self that is founded upon a ?theory of mind,? Welsh challenges the notion that neonates have the capacity for self-awareness and charges the supposition with an essentialism which threatens to disrupt more social constructionist understandings of the self. In (...) this paper, I initially defend Gallagher and Meltzoff's (1996) application of infant imitation to understandings of neonatal self-awareness by explaining how body image schemas can be understood as non-representational embodied cognitive phenomena that challenge ?theory of mind? theory. I then further develop the claim that neonates are born self-aware with reference to my own work in fetal development. I conclude that Welsh's political concerns are unfounded by showing how the conclusion that a neonate is self-aware does not signal a return to an essentialist understanding of self-awareness, but rather introduces into philosophical and psychological discourse possible alternate understandings of an embodied sense of self that are embedded within intersubjective contexts.

The lambda model of servocontrol seems superior to the alpha model in terms of dealing with the mechanical complexities of nonlinear and multiarticular muscles. Both, however, can be trivialized by noting that the “control variable” may simply be the sum of descending influences at propriospinal interneurons in the case of the lambda model or in the muscles themselves in the case of the alpha model. The notion that the brain explicitly computes output in terms of any such control variables may (...) be an engineering metaphor, useful for conceptual understanding but not for generating predictive hypotheses about higher motor circuitry.

Feldman and Levin present a model for movement control in which the system is said to seek equilibrium points, active movement being produced by shifting frames of reference in space. It is argued that whatever merit this model might have is limited to an understanding of “the how” and not “the why” we move. In this way the authors seem to be forced into a dualistic position leaving the upper level of the proposed control hierarchy “floating.”.

Accounting for phenomenal structure—the forms, aspects, and features of conscious experience—poses a deep challenge for the scientific study of consciousness, but rather than abandon hope I propose a way forward. Connectionism, I argue, offers a bi-directional analogy, with its oft-noted “neural inspiration” on the one hand, and its largely unnoticed capacity to illuminate our phenomenology on the other. Specifically, distributed representations in a recurrent network enable networks to superpose categorical, contextual, and temporal information on a specific input representation, much as (...) our own experience does. Artificial neural networks also suggest analogues of four salient distinctions between sensory and nonsensoty consciousness. The paper concludes with speculative proposals for discharging the connectionist heuristics to leave a robust, detailed empirical theory of consciousness. (shrink)

One of the major divergences between dynamical systems theory and symbolism lies in their views on the role of representation in cognition. From the perspective of development, the cognitive development could be divided into three levels: sensorimotor, imagery representation and linguistic representation. It is claimed that representation is not a sufficient condition though it is necessary for cognition. However, it does not mean that the authors agree with the notion of strong coupling in dynamicism that completely rejects representation.
