No mental phenomenon is more central than consciousness to an adequate understanding of the mind. Nor does any mental phenomenon seem more stubbornly to resist theoretical treatment. Consciousness is so basic to the way we think about the mind that it can be tempting to suppose that no mental states exist that are not conscious states. Indeed, it may even seem mysterious what sort of thing a mental state might be if it is not a conscious state. On this way (...) of looking at things, if any mental states do lack consciousness, they are exceptional cases that call for special explanation or qualification. Perhaps dispositional or cognitive states exist that are not conscious, but nonetheless count as mental states. (shrink)

When do children become aware of themselves as differentiated and unique entity in the world? When and how do they become self-aware? Based on some recent empirical evidence, 5 levels of self-awareness are presented and discussed as they chronologically unfold from the moment of birth to approximately 4-5 years of age. A natural history of children's developing self-awareness is proposed as well as a model of adult self-awareness that is informed by the dynamic of early development. Adult self-awareness is viewed (...) as the dynamic flux between basic levels of consciousness that develop chronologically early in life. (shrink)

Human self-consciousness operates at different levels of complexity and at least comprises five different levels of representational processes. These five levels are nonconceptual representation, conceptual representation, sentential representation, meta-representation, and iterative meta-representation. These different levels of representation can be operationalized by taking a first-person-perspective that is involved in representational processes on different levels of complexity. We refer to experiments that operationalize a first-person-perspective on the level of conceptual and meta-representational self-consciousness. Interestingly, these experiments show converging evidence for a recruitment of (...) medial cortical and parietal regions during taking a first-person-perspective, even when operating on different degrees of complexity. These data lend support for the speculative hypothesis, that there exist a neural signature for human self-consciousness that is recruited independent from the degree of representational complexity to be performed.

Ce texte propose une définition de la conscience de soi et explique en quoi cette capacité naît du monde social. Il est postulé que ce dernier permet un mouvement de recul - une «distanciation » - par rapport à soi, et que le cerveau reproduit ce mouvement grâce à certains processus cognitifs qui en ont été imprimés. Parmi ceux-ci, on retrouve le langage intérieur, qui, par analogie, agirait comme un miroir interne capable de confronter l'expérience subjective à elle-même; de cette (...) confrontation naîtrait le soi. Un argument est présenté en faveur de la supériorité du langage intérieur sur d'autres processus cognitifs impliqués dans la conscience de soi. Le problème de la conscience de soi chez les primates est abordé, et l'article conclut sur diverses réflexions ayant trait à la schizophrénie, la prière, la méditation, et les drogues psychodysleptiques.This text proposes a definition of self-awareness and explains its social origin. It is postulated that the social milieu permits a movement to a more objective perspective for self- perception, and that this movement is then reproduced in the brain by specific cognitive processes. It is suggested that inner speech represents one such cognitive processes, which acts like a mirror to reflect subjective experience back upon itself-, the self would be generated by this reflective activity. It is argued that inner speech has a pre-eminent position among the cognitive processes implicated in self-awareness. The problem of self-awareness in primates is discussed, and the article concludes with ideas concerning schizophrenia, prayer, medi- tation, and psychodysleptic drugs. (shrink)

Since its inception as a topic of inquiry, mirror-self-recognition has usually been explained by two models: one, initiated by Guillaume, proposes that mirror-self-recognition depends upon kinesthetic-visual matching, and the other, initiated by Gallup, that self-recognition depends upon a self-concept. These two models are examined historically and conceptually. This examination suggests that the kinesthetic-visual matching model is conceptually coherent and makes reasonable and accurate predictions; and that the self-concept model is conceptually incoherent and makes inaccurate predictions from premises which are themselves (...) inaccurate. From a theoretical standpoint, the kinesthetic-visual matching model is the better explanation of self-recognition. (shrink)

Previous discussions of the evolution of the self have diverged greatly in their estimates of the date at which the capacity for self-thought emerged, the factors that led self-reflection to evolve, and the nature of the evidence offered to support these disparate conclusions. Beginning with the assumption that human self-awareness involves a set of distinct cognitive abilities that evolved at different times to solve different adaptive problems, we trace the evolution of self-awareness from the common ancestor of humans and apes (...) to the beginnings of culture, drawing upon paleontological, anthropological, biological, and psychological evidence. These data converge to suggest that that modern self-thought appeared just prior to the Middle-Upper Paleolithic transition, approximately 60,000 years ago.Recto running head: Evolution of the Self.

Since the BBS article in which Premack and Woodruff (1978) asked “Does the chimpanzee have a theory of mind?,” it has been repeatedly claimed that there is observational and experimental evidence that apes have mental state concepts, such as “want” and “know.” Unlike research on the development of theory of mind in childhood, however, no substantial progress has been made through this work with nonhuman primates. A survey of empirical studies of imitation, self-recognition, social relationships, deception, role-taking, and perspective-taking suggests (...) that in every case where nonhuman primate behavior has been interpreted as a sign of theory of mind, it could instead have occurred by chance or as a product of nonmentalistic processes such as associative learning or inferences based on nonmental categories. Arguments to the effect that, in spite of this, the theory of mind hypothesis should be accepted because it is more parsimonious than alternatives or because it is supported by convergent evidence are not compelling. Such arguments are based on unsupportable assumptions about the role of parsimony in science and either ignore the requirement that convergent evidence proceed from independent assumptions, or fail to show that it supports the theory of mind hypothesis over nonmentalist alternatives. Progress in research on theory of mind requires experimental procedures that can distinguish the theory of mind hypothesis from nonmentalist alternatives. A procedure that may have this potential is proposed. It uses conditional discrimination training and transfer tests to determine whether chimpanzees have the concept “see.” Commentators are invited to identify flaws in the procedure and to suggest alternatives.

Although philosophical approaches to the self are diverse, several of them are relevant to cognitive science. First, the notion of a 'minimal self', a self devoid of temporal extension, is clarified by distinguishing between a sense of agency and a sense of ownership for action. To the extent that these senses are subject to failure in pathologies like schizophrenia, a neuropsychological model of schizophrenia may help to clarify the nature of the minimal self and its neurological underpinnings. Second, there is (...) good evidence to suggest that although certain aspects of the minimal self are primitive and embodied, other aspects may be accessed only in reflective consciousness. Employing a modified concept of the minimal self, it may be possible to construct a robotic form of non-conscious self-reference that depends on an interaction between the robotic body and its environment. In contrast to the minimal self, the narrative self involves continuity over time and is directly relevant to discussions of memory and personal identity. There is growing consensus among philosophers and cognitive scientists about the importance of narrative and its relation to episodic memory and left-hemisphere functions. There are, however, at least two different views of how the narrative self is structured. On one model it is nothing more than an abstract point. On a more extended view, proposed here, the self is a rich amalgam of narratives that allows for the equivocations, contradictions, and self-deceptions of personal life. Even in this case, however, neurocognitive models contribute to our understanding of how narrative identity is structured. (shrink)

We argue that cognitive empathy and other instances of mental state attribution are a byproduct of self-awareness. Evidence is brought to bear on this proposition from comparative psychology, early child development, neuropsychology, and abnormal behavior.

How do I know that I am the person who is moving? According to Wittgenstein (1958), the sense of agency involves a primitive notion of the self used as subject, which does not rely on any prior perceptual identification and which is immune to error through misidentification. However, the neuroscience of action and the neuropsychology of schizophrenia show the existence of specific cognitive processes underlying the sense of agency—the ‘‘Who'' system (Georgieff & Jeannerod, 1998) which is disrupted in delusions of (...) control (Frith, 1992). Yet, we have to be careful in the interpretation of such clinical symptoms, which cannot be so easily reduced to deficit of action monitoring or to lack of action awareness. Moreover, we should refine the definition of the sense of agency by distinguishing the sense of initiation and the sense of one's own movements. A conceptual analysis of the empirical data will lead us to establish the taxonomy of the different levels of action representations. (shrink)

Little, Brown, 1992 Review by Glenn Branch on Jul 5th 1999 Volume: 3, Number: 27.

The publication of this book is an event in the making. All over the world scientists, psychologists, and philosophers are waiting to read Antonio Damasio's new theory of the nature of consciousness and the construction of the self. A renowned and revered scientist and clinician, Damasio has spent decades following amnesiacs down hospital corridors, waiting for comatose patients to awaken, and devising ingenious research using PET scans to piece together the great puzzle of consciousness. In his bestselling Descartes' Error, Damasio (...) revealed the critical importance of emotion in the making of reason. Building on this foundation, he now shows how consciousness is created. Consciousness is the feeling of what happens-our mind noticing the body's reaction to the world and responding to that experience. Without our bodies there can be no consciousness, which is at heart a mechanism for survival that engages body, emotion, and mind in the glorious spiral of human life. A hymn to the possibilities of human existence, a magnificent work of ingenious science, a gorgeously written book, The Feeling of What Happens is already being hailed as a classic. (shrink)

Do we conduct our conscious propositional thinking in natural language? Or is such language only peripherally related to human conscious thought-processes? In this paper I shall present a partial defence of the former view, by arguing that the only real alternative is eliminativism about conscious propositional thinking. Following some introductory remarks, I shall state the argument for this conclusion, and show how that conclusion can be true. Thereafter I shall defend each of the three main premises in turn.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

The use of expressions like ‘concepts of consciousness’, ‘kinds of consciousness’, and ‘meanings of ‘consciousness’’ interchangeably is ubiquitous within the consciousness literature. It is argued that this practice can be made sense of in only two ways. The first involves interpreting ‘concepts of consciousness’ and ‘kinds of consciousness’ metalinguistically to mean concepts expressed by ‘consciousness’ and kinds expressed by ‘consciousness’; and the second involves certain literal, though semantically deviant, interpretations of those expressions. The trouble is that researchers typically use the (...) above expressions interchangeably without satisfying either way of doing so coherently. The result is much error and confusion, which is demonstrated in the works of philosophers currently writing on consciousness. (shrink)

How do we know who we are? When and how did we become aware of our presence and thoughts? Why do some species develop self-awareness, while others do not? This question of self-awareness and consciousness has puzzled philosophers and scientists alike, from Aristotle and Darwin to Descartes and William James. In his famous "mirror test" thirty years ago, leading researcher Gordon G. Gallup Jr. showed that self-awareness begins with the recognition of one’s reflection in the mirror, an ability that only (...) higher order primates possess. In The Face in the Mirror, Julian Paul Keenan, Gordon G. Gallup Jr., and Dean Falk further explore mirror recognition as the key to understanding the origins of consciousness and its role in our evolution, everyday behavior, and ongoing survival. For the past decade, Julian Paul Keenan and his colleagues have been closing in on the source of self-awareness in the brain. With the advent of MRI technology and other techniques, they have examined the hypothesis that there is a brain network specifically involved in self-recognition. This book shows how the right hemisphere of the brain (where mirror recognition takes place), often relegated to "supporting role" status, may be a more crucial determinant of higher order consciousness. Keenan also shows how recognizing our reflection -- an ability we take for granted -- is linked to such common self-related functions as memory and to emotions like empathy, narcissism, and deception, which play a crucial role in evolution. Insightful, witty, and accessible, The Face in the Mirror plunges the reader into the forefront of thedebate on consciousness in humans and primates. From animals who share our ability for self-recognition, to the development of self-awareness in children, to case studies of patients who no longer recognize who they are, Keenan examines some of the latest evidence in the fields of neurology, psychology, and anthropology and suggests remarkable and surprising results about the function of self-awareness in humans and other primates.

been recently proposed (Morin, 2003; 2004). The model takes into account most known mechanisms and processes leading to self-awareness, and examines their multiple and complex interactions. Inner speech is postulated to play a key-role in this model, as it establishes important connections between many of its ele- ments. This paper first reviews past and current references to a link between self-awareness and inner speech. It then presents an analysis of the nature of the relation between these two concepts. It is (...) suggested that inner speech can inter- nally reproduce and expand social and physical (ecological) sources of self- awareness. Inner speech can also create a psychological distance between the self and mental events it experiences (thus facilitating self-observation) it can act as a problem-solving device where the self represents the problem and self-information the solution, and can label aspects of one’s inner life that would otherwise be difficult to objectively perceive. Empirical evidence supporting the role of inner speech in self-awareness is also presented. (shrink)

Published in two parts, the present article addresses whether self-awareness is necessarily involved in each of the six kinds of consciousness that The Oxford English Dictionary identifies under the word consciousness. Part I inquires into how, if at all, self-awareness enters consciousness1: a cognitive relation between people in which they have joint and mutual cognizance; consciousness2: a psychological process of conceiving of oneself in certain sorts of respects on a firsthand evidentiary basis; and consciousness3: being occurrently aware of anything at (...) all, including nonexistent particulars. An instance of consciousness1 may or may not have a reflexive object, but it will perforce include both inner awareness and awareness of oneself as an object of the other’s awareness. Consciousness2 requires self-awareness in the forms of witnessing or having witnessed potential evidence about oneself, inner awareness of this witnessing when it occurred, inner awareness and self-awareness as involved in remembering having witnessed that evidence, occurrent awareness of features of one’s character or personality, and bringing self-witnessed evidence to bear in judging of the latter. In contrast, consciousness3, which in a particular instance may be an occurrent self-awareness, need not involve any self-awareness at all. (shrink)

It is widely assumed that ‘ consciousness ’ is multiply ambiguous within the consciousness literature. Some alleged senses of the term are access consciousness, phenomenal consciousness, state consciousness, creature consciousness, introspective consciousness, self consciousness, to name a few. In the paper I argue for two points. First, there are few if any good reasons for thinking that such alleged senses are genuine: ‘ consciousness ’ is best viewed as univocal within the literature. The second point is that researchers would do (...) best to avoid the semantics of ‘ consciousness ’, since resorting to “semantic ascent” typically serves no clear purpose in the case of consciousness, and confuses matters more than anything else.

This article raises the question of how we acquire self-information through self-talk, i.e., of how self-talk mediates self-awareness. It is first suggested that two social mechanisms leading to self-awareness could be reproduced by self-talk: engaging in dialogues with ourselves, in which we talk to fictive persons, would permit an internalization of others' perspectives; and addressing comments to ourselves about ourselves, as others do toward us, would allow an acquisition of self-information. Secondly, it is proposed that self-observation is possible only if (...) there exists a distance between the individual and any potentially observable self-aspect; self-talk, because it conveys self-information under a different form , would create a redundancy -- and with it, a wedge -- within the self.

As soon as we stop talking aloud, we seem to experience a kind of 'inner voice', a steady stream of verbal fragments expressing ongoing thoughts. What kind of information processing structures are required to explain such a phenomenon? Why would an 'inner voice' be useful? How could it have arisen? This paper explores these questions and reports briefly some computational experiments to help elucidate them.
