This paper proposes a brain-inspired cognitive architecture that incorporates approximations to the concepts of consciousness, imagination, and emotion. To emulate the empirically established cognitive efficacy of conscious as opposed to non-conscious information processing in the mammalian brain, the architecture adopts a model of information flow from global workspace theory. Cognitive functions such as anticipation and planning are realised through internal simulation of interaction with the environment. Action selection, in both actual and internally simulated interaction with the environment, (...) is mediated by affect. An implementation of the architecture is described which is based on weightless neurons and is used to control a simulated robot. (shrink)

This article presents a formal theory of robot perception as a form of abduction. The theory pins down the process whereby low‐level sensor data is transformed into a symbolic representation of the external world, drawing together aspects such as incompleteness, top‐down information flow, active perception, attention, and sensor fusion in a unifying framework. In addition, a number of themes are identified that are common to both the engineer concerned with developing a rigorous theory of perception, such as the one on (...) offer here, and the philosopher of mind who is exercised by questions relating to mental representation and intentionality.

This paper presents a computer model of cortical broadcast and competition based on spiking neurons and inspired by the hypothesis of a global neuronal workspace underlying conscious information processing in the human brain. In the model, the hypothesised workspace is realised by a collection of recurrently inter-connected regions capable of sustaining and disseminating a reverberating spatial pattern of activation. At the same time, the workspace remains susceptible to new patterns arriving from outlying cortical populations. Competition among these cortical populations for (...) influence on the workspace is effected by a combination of mutual inhibition and top-down amplification. (shrink)

According to the singularity hypothesis, rapid and accelerating technological progress will in due course lead to the creation of a human-level artificial intelligence capable of designing a successor artificial intelligence of significantly greater cognitive prowess, and this will inaugurate a series of increasingly super-intelligent machines. But how much sense can we make of the idea of a being whose cognitive architecture is qualitatively superior to our own? This article argues that one fundamental limitation of human cognitive architecture (...) is an inbuilt commitment to a metaphysical division between subject and object, a commitment that could be overcome in an artificial intelligence lacking our biological heritage.

Novice designers produced a sequence of sketches while inventing a logo for a novel brand of soft drink. The sketches were scored for the presence of specific objects, their local features and global composition. Self‐assessment scores for each sketch and art critics' scores for the end products were collected. It was investigated whether the design evolves in an essentially random fashion or according to an overall heuristic. The results indicated a macrostructure in the evolution of the design, characterized by two (...) stages. For the majority of participants, the first stage is marked by the introduction and modification of novel objects and their local and global aspects; the second stage is characterized by changes in their global composition. The minority that showed the better designs has a different strategy, in which most global changes were made in the beginning. Although participants did not consciously apply these strategies, their self‐assessment scores reflect the stages of the process. (shrink)

Artificial Intelligence is making rapid and remarkable progress in the development of more sophisticated and powerful systems. However, the acknowledgement of several problems with modern machine learning approaches has prompted a shift in AI benchmarking away from task-oriented testing towards ability-oriented testing, in which AI systems are tested on their capacity to solve certain kinds of novel problems. The Animal-AI Environment is one such benchmark which aims to apply the ability-oriented testing used in comparative psychology to AI systems. Here, we (...) present the first direct human-AI comparison in the Animal-AI Environment, using children aged 6–10. We found that children of all ages were significantly better than a sample of 30 AIs across most of the tests we examined, as well as performing significantly better than the two top-scoring AIs, “ironbar” and “Trrrrr,” from the Animal-AI Olympics Competition 2019. While children and AIs performed similarly on basic navigational tasks, AIs performed significantly worse in more complex cognitive tests, including detour tasks, spatial elimination tasks, and object permanence tasks, indicating that AIs lack several cognitive abilities that children aged 6–10 possess. Both children and AIs performed poorly on tool-use tasks, suggesting that these tests are challenging for both biological and non-biological machines. (shrink)

Our aim in this reply is to defend Global Workspace theory (GWT) from the challenge of Block's article. We argue that Block's article relies on an outdated and imprecise concept of access, and perpetuates a common misunderstanding of GWT that conflates the global workspace with working memory. In the light of the relevant clarifications, Block's conclusion turns out to be unwarranted, and the basic tenets of GWT emerge unscathed.

The objectives of this article are twofold. First, by denying the dualism inherent in attempts to load metaphysical significance on the inner/outer distinction, it defends the view that scientific investigation can approach consciousness in itself, and is not somehow restricted in scope to the outward manifestations of a private and hidden realm. Second, it provisionally endorses the central tenets of global workspace theory, and recommends them as a possible basis for the sort of scientific understanding of consciousness thus legitimised. However, (...) the article goes on to argue that global workspace theory alone does not constitute a fully worked-out objective account of the conscious subject. This requires additional attention to be paid to the issue of embodiment, and to the possibility of indexicality that arises when an instantiation of the global workspace architecture inhabits a spatially localised body.

Cognitive Robotics can be defined as the study of cognitive phenomena by their modeling in physical artifacts such as robots. This is a very lively and fascinating field which has already given fundamental contributions to our understanding of natural cognition. Nonetheless, robotics has to date addressed mainly very basic, low­level cognitive phenomena like sensory­motor coordination, perception, and navigation, and it is not clear how the current approach might scale up to explain high­level human cognition. In (...) this paper we argue that a promising way to do that is to merge current ideas and methods of 'embodied cognition' with the Russian tradition of theoretical psychology which views language not only as a communication system but also as a cognitive tool, that is by developing a Vygotskyan Cognitive Robotics. We substantiate this idea by discussing several domains in which language can improve basic cognitive abilities and permit the development of high­level cognition: learning, categorization, abstraction, memory, voluntary control, and mental life.

Midway in the process of inquiring about what it means “to know,” Socrates is stopped short by a thought that seems to render the whole undertaking questionable.

In this study of the works of Sren Kierkegaard, Murray Rae focuses on his understanding of the Christian faith and the nature of Christian conversion. The transformation of an individual under the impact of revelation is explored both in terms of the New Testament concept of metanoia and in comparison with claims to cognitive progress in other fields.

It is difficult to overestimate the impact, beginning in the 1960s, which Gombrich’s discussion of visual representation made on a good number of theorists in an entire generation of thinking about art and—even more—about literary art. For literary theory and criticism were at least as affected by his work as were theory and criticism in the plastic arts. Art and Illusion radically undermined the terms which had controlled discussion of how art represented “reality”—or, rather, how viewers or members of the (...) audience perceived that representation and related it to their versions of “reality.” And, for those who accompanied or followed him—from Rosalie Colie to Wolfgang Iser—Gombrich helped transform for good the meaning of a long revered term like “imitation” as it could be applied to both the visual and verbal arts. I believe he must, then, be seen as responsible for some of the most provocative turns that art theory, literary theory, and aesthetics have taken in the last two decades.In much of his work since the 1960s, however, Gombrich has appeared more and more anxious to dissociate himself from those who have treated his earlier books and essays as leading to the theoretical innovations which have claimed support from them. In The Image and the Eye, the statements which put distance between himself and such followers seem utterly unambiguous. And against the charge that his work has become more conservative with the passing years, I suspect Gombrich would argue that any claim of difference between, say, Art and Illusion and The Image and the Eye is a result of an original misreading, that the recent work is only more explicitly defending a traditional position which was quietly there all along, though supposedly friendly theorists wrongly saw him as subverting it in the earlier work. Thus Gombrich is now self-consciously committed to undoing what he sees as our errors of reading rather than his own errors of writing.

Many people have long-term commitments that require coordination and cooperation with others. To achieve this, we construct plans to settle when, how, and for how long to pursue certain goals rather than others. This raises an interesting cognitive problem, namely that individuals can, at any given moment, manage significantly less information than they will need to accomplish their goals. Call this the Problem of Scarce Information. The solution requires a special self-regulatory system that strategically manages the varying informational demands (...) of one's activity. This paper argues that vigilance has structural and functional characteristics that make it apt to play this role. This paper illuminates both crucial aspects of temporally extended agency, but also the unique practical norms that structure how we act over time. (shrink)

Our usual view of the Renaissance poetic, as we derive it from the explicit statements which we normally cite, sees it primarily as a rhetorical theory which is essentially Platonic in the universal meanings behind individual words, images, or fictions. Accordingly, poetic words, images, or fictions are taken to be purely allegorical, functioning as arbitrary or at most as conventional signs: each word, image, or fiction is seen as thoroughly dispensable, indeed interchangeable with others, to be used just so long (...) as we can get beyond it to the ultimate meaning which it presumably signifies. This rather simple—if not simplistic—semiology leaves the body of poetry as empty as modern post-Saussurean linguistics often leaves the body of language. By treating all poetic devices as transparent elements through which various universal "truths" are revealed, the rhetorical/allegorical theory converts all the poet's dispositions of words into devices of persuasion on the service of a function higher than that of poetry. Such is the way that, for example, a conservative, widely influential theorist like Scaliger clearly formulated the principle. And for as careful a commentator on Renaissance imagery as Rosemund Tuve, these are the farthest reaches of the Renaissance poetic; she argues that any more subtle a claim is merely the consequence of the modern mind trying anachronistically to sophisticate an older tradition. Her examination of explicit statements by major Renaissance writers on poetics finds reinforcement in the logic of Petrus Ramus as she extends it to a total stylistics, or even to a linguistics.1 · 1.

In Reconstructing Reason and Representation, Murray Clarke offers a detailed study of the philosophical implications of evolutionary psychology. In doing so, he offers new solutions to key problems in epistemology and philosophy of mind, including misrepresentation and rationality. He proposes a naturalistic approach to reason and representation that is informed by evolutionary psychology, and, expanding on the massive modularity thesis advanced in work by Leda Cosmides and John Tooby, argues for a modular, adapticist account of misrepresentation and knowledge. Just (...) as the reliability of representation can be defended on the basis of an account of the proper function of cognitive modularity, misrepresentation can be explained through an appeal to the "gap theory," by noting the divergence between the proper and actual domains of cognitive modules in a massively modular mind.Clarke argues for an externalist, modular reliabilism by suggesting that evolution has equipped us with generally reliable inferential systems even if they do not always produce true beliefs. He argues that reliable deductive and inductive inference occurs only when cognitive modules deal with actual domains that are sufficiently similar to their proper domains. This psychologically informed, naturalized adapticism leads to the suggestion that knowledge is a set of natural kinds housed in the modules of a massively modular mind. Typically, the proper function of these cognitive modules is to provide us with truths that enable us to satisfy our basic biological needs. Beyond reasoning modules, other cognitive modules discussed include the ability to orient ourselves in space, and our abilities with language, numbers, object reasoning, and social understanding. Clarke also defends Cosmides and Tooby's massive modularity hypothesis against such critics as Jerry Fodor by demonstrating that these critics consistently misrepresent Cosmides and Tooby's position.

Spoken communication between social robotic devices, powered by generative AI tools such as ChatGPT, and the senior population offers great potential for researching social interaction and robot identity perceptions as well as exploring the potential opportunities and challenges when implementing this human-machine interactions in real life situations and health care. In this paper we explore people’s perceptions of the social robot Furhat when administering verbal tasks similar to those used in screening for Alzheimer’s disease. We describe the Slovak system mounted (...) on the robot that includes a speech recognizer, the scenarios powered by generative large language model ChatGPT, and a speech synthesizer. We tested the functionality of the proposed approach with two groups of participants: attendees of a large science fair and a scientific conference. The observations from 87 collected questionnaires suggest good potential and applicability of such an approach for the given task and more positive attitudes of older subjects compared to younger ones.

Over the last decade a handful of cognitive models of religious belief have begun to coalesce in the literature. Attempts to offer “scientific explanations of religious belief ” are nothing new, stretching back at least as far as David Hume, and perhaps as far back as Cicero. What is also not new is a belief that scientific explanations of religious belief serve in some way to undermine the justification for those beliefs.

I begin by asking an engagingly naive question that a layman would have every right to put to us - and often has. Why should we interest ourselves seriously in the once-upon-a-time worlds of fiction - these unreal stories about unreal individuals? It has been a persistent question in the history of criticism - ever since Plato called the poet a liar - and it is a question at once obvious and embarrassing. It is obvious because, for the apologist for (...) imaginative literature, it becomes a prolegomenon to all further questions; and it is embarrassing because merely to ask it threatens to put literature out of business and, with it, all those who treat it as a serious and world-affecting art. Why, then, should we interest ourselves seriously in fictions? However elementary, it is a question that is more easily asked than answered.

Zbigniew Herbert studied philosophy at the Nicolaus Copernicus University in Toruń in the years 1949–1951 and attended seminars conducted by prof. Henryk Elzenberg, whose philosophical stance had a relevant impact on the poet’s oeuvre. This work analyses Stoic heritage present in the works of both the Philosopher and the Poet, as well as presents the axiological system of Elzenberg and its meaning for the attitude of “Mr. Cogito”. Elzenberg, following Seneca, divided values into the utilitarian and perfect ones, where the (...) latter possessed the quality of dignitas (“nobleness”). The perfect values referred to the Greek notion of kalokagathia and they were of primary importance in the creation of high culture that constituted the sphere of human dignity and freedom as opposed to the existential dread, indifference of nature or historical necessity. Herbert shared his Master’s stand on the meaning of culture and the table of values in human life, which is depicted, inter alia, in the poem dedicated to the Professor To Henryk Elzenberg on the Centenary of His Birth. Elzenberg claimed that axiologization the the world equals its substantialization. Finally, the acme of his axiology became natural mysticism and the source of perfect value the “transempirical” reality which Elzenberg used to call “the Undefined”. The Professor was distanced and sceptical towards the world and society. Herbert, on the other hand, remained faithful to the Christian heritage with its confirmation of the world as it is, as well as the everyday human reality, which he treated with sympathy and uderstanding, according to the idea of Christian agape.

To effectively improve the efficiency of international service design talent training and make it more in line with society's needs, we analyze the current status of international service design talent training and its professional training focus. Based on the above problems, from the perspective of cognitive psychology, artificial intelligence and human–computer interaction technology are used to construct the international service design talent training mode of the HCI intelligent service robot. This mode can be used to solve the existing teaching (...) problems by using novel means to ensure the quality of teaching. Finally, through the actual analysis of teaching cases, the effectiveness of the proposed talent training mode is verified. The HCI system is based on knowledge of cognitive psychology. According to the characteristics and functions of an educational robot, the robot is combined with traditional teaching activities, and the robot-assisted talent training mode is designed. Robot-assisted talent training is a feasible training method that can improve the efficiency of talent training. Students have confidence in their learning skills before the course, and the confidence is further strengthened after the end of the course. After the course, the students have a stronger sense of cooperation. This study can provide theoretical ideas for the research of international service talent training mode. (shrink)

I am troubled by the temper of E. H. Gombrich’s response, “Representation and Misrepresentation” , to my “Ambiguities of Representation and Illusion: An E. H. Gombrich Retrospective” and by his preferring not to sense the profound admiration—indeed, the homage—intended by my essay, both for his contributions to recent theory and for their influence upon its recent developments. But I am more troubled by the confusions his remarks may cause in the interpretation of his own work as well as in the (...) judgment of mine. There are important issues at stake, I feel, especially as regards the relation between scientific and aesthetic inquiry.The very irritated tone of his reaction helps make what I see as my major point: his work has contained a conflict between two Gombrichs—one, the skeptical humanist and, the other, the positive scientist—and with the passing years the second has increasingly sought to obliterate signs of the first, becoming increasingly impatient with any attempt to revive those signs or remind us of their existence. On the other side, since the line of literary criticism with which I associate myself has drawn strength from the first Gombrich, this development in his work and in his attitudes has caused some disappointment.

There is a definite challenge in the air regarding the pivotal notion of internal representation. This challenge is explicit in, e.g., van Gelder, 1995; Beer, 1995; Thelen & Smith, 1994; Wheeler, 1994; and elsewhere. We think it is a challenge that can be met and that (importantly) can be met by arguing from within a general framework that accepts many of the basic premises of the work (in new robotics and in dynamical systems theory) that motivates such scepticism in (...) the first place. Our strategy will be as follows. We begin (Section 1) by offering an account (an example and something close to a definition) of what we shall term Minimal Robust Representationalism (MRR). Sections 2 & 3 address some likely worries and questions about this notion. We end (Section 4) by making explicit the conditions under which, on our account, a science (e.g., robot- ics) may claim to be addressing cognitive phenomena. (shrink)

In 1772, Kant outlined the new problem of his critical period in terms of four possible “ways” of understanding the agreement of knowledge with its object. This study expands Kant’s terse descriptions of these ways, examining why he rejected them. Apart from clarifying the historical context in which Kant saw his own achievement (the Fifth Way), the chief benefits of exploring the historical background of Way Two, in particular, are that it (1) explains the puzzling intuitus originarius/intellectus archetypus dichotomy, and (...)

The idea that human history evinces a pattern of development rooted in the propensity of human beings toward technical forms of rationality is fundamental to Marx's materialist conception of history. Yet the "dialectic of forces and relations of production" as traditionally conceived in historical-materialist discourse has found only weak expressions in social formations dominated by precapitalist modes of production. The hypothesis is advanced that the role of simple commodity production and exchange in such formations may be decisive to the emergence (...) of cognitive faculties capable of giving a systematic impulse to the development of science and technology, and therefore to a precapitalist forces-relations dialectic. This suggests a new way of appreciating Marx's "ranking" of the Asiatic, ancient, feudal and capitalist modes of production as "progressive epochs" in the development of human society, while illuminating the socio-historical provenance (and sources of variability) of the categories of human thought.

If there is one rationality there must be a plurality of them. This conclusion follows, I argue, partly from the extreme and ineradicable vagueness of the fundamental concepts that every would‐be rational explanation must presuppose. Logicistic/scientistic assaults on this vagueness are doomed to fail partly because they are unable to acknowledge the imaginative dimension of rational thought. Being limited to the play of “outward appearances,” scientific investigations are also dependent on “inward imaginings” on their speculative side. The upshot is that (...) schools of philosophy should be characterized by the kind of imaginary they adopt rather than by their logics. In which case, every attempt to get and tell something right about the world is bound to incorporate mythopoeic elements in its explanations. (shrink)

Does self-control require willpower? The question cuts to the heart of a debate about whether self-control is identical with some psychological process internal to the agents or not. Noticeably absent from these debates is systematic evidence about the folk-psychological category of self-control. Here, we present the results of two behavioral studies (N = 296) that indicate the structure of everyday use of the concept. In Study 1, participants rated the degree to which different strategies to respond to motivational conflict exemplify (...) self-control. Participants distinguished between intra-psychic and externally-scaffolded strategies and judged that the former exemplified self-control more than the latter. In Study 2, participants provided various solutions to manage motivational conflict and rated their proposals on effectiveness. Participants produced substantially more intra-psychic strategies, rated them as more effective, and advised them at a higher rate than externally-scaffolded strategies. Taken together, these results suggest that while people recognize a plurality of strategies as genuine instances of self-control, purely internal exercises of self-control are considered more prototypical than their externally-scaffolded counterparts. This implies a hierarchical structure for the folk psychological category of self-control. The concept encompasses a variety of regulatory strategies and organizes these strategies along a hierarchical continuum, with purely intra-psychic strategies at the center and scaffolded strategies in the periphery.

The analytic method by which Descartes discovered the first principle of his philosophy—cogito, ergo sum—is a unique cognitive process of direct insight and nonlogical inference. It differs markedly from inductive as well as deductive procedures, but also from older models of the direct noetic apprehension of first principles, notably those of Plato and Aristotle. However, a critical examination of Descartes’s argument for the innateness of the idea of God shows that there are serious obstacles in the way of his (...) employment of the analytic method of discovery to reach this or any other conclusion about ideas that do not fall within the scope of ordinary human experience.

In this second of a 2-part survey of Aristotle’s epistemology, I present an overview of Aristotle’s views on technē (craft or excellent productive reason) and phronēsis (practical wisdom or excellent practical reason). For Aristotle, attaining the truth in practical matters involves actually doing the right action. While technē and phronēsis are rational excellences, for Aristotle they are not as excellent or true as epistēmē or nous because the kinds of truth that they grasp are imperfect and because they are excellent (...) states for humans, not simply speaking. I then discuss why Aristotle takes sophia (wisdom), understanding and scientific knowledge of the best things, to be its own excellence. While this is the best cognitive state for human beings, I argue that Aristotle thinks divine cognitive activity is different in kind and more perfect than any human activity. (shrink)
