Memory is a general attribute of living species, whose diversification reflects both evolutionary and developmental processes. Episodic-autobiographical memory is regarded as the highest human ontogenetic achievement and as probably being uniquely human. EAM, autonoetic consciousness and the self are intimately linked, grounding, supporting and enriching each other’s development and cohesiveness. Their development is influenced by the socio-cultural–linguistic environment in which an individual grows up or lives. On the other hand, through language, textualization and social exchange, all three elements leak into (...) the world and participate to the dynamic shaping and re-shaping of the cultural scaffolding of the self, mental time traveling and EAM formation. Deficits in self-related processing, autonetic consciousness, emotional processing and mental time traveling can all lead to or co-occur with EAM disturbances, as we illustrate by findings from EAM impairments associated with neurological or psychiatric disorders.

The idea of distinct brain systems for the processing of episodic and other forms of memory is welcome. The two brain systems actually proposed however, appear to be stripped of further existing connections and could be integrated with one another. If integrating them, it seems more logical to propose one enlarged system of limbic structures whose individual components make partly different contributions to the forms of memory under discussion.

Barzykowski and Moulin link déjà vu and involuntary autobiographical memories to the process of retrieval. They make no reference to Tulving's SPI-model. In this, it is proposed that information is acquired serially (S), stored in parallel (P), and retrieved independently (I). This model offers an alternative, elegant, view of involuntary autobiographical memory retrieval, as well as of déjà vus.

It is argued that Llewellyn's hypothesis about the lack of rapid eye movement (REM)-sleep dreaming leading to loss of personal identity and deficits in episodic memory, affectivity, and prospection is insufficiently grounded because it does not integrate data from neurodevelopmental studies and makes reference to an outdated definition of episodic memory.

Der Begriff ‚Gedächtnis‘ wird im Deutschen in verschiedenen Bedeutungen gebraucht: Im Sinne eines kollektiven Gedächtnisses, das in erster Linie ein kulturelles Gedächtnis ist; im Sinne von Gedenken (memoria) und im Sinne von Erinnerung, also dem Aufnehmen, Abrufen und Ordnen von Informationen, Begebenheiten und Ereignissen aus der Vergangenheit. Letzteres hat primär eine Funktion für einzelne lebende Organismen und betrifft deren Fähigkeit, aus vergangenen Ereignissen Orientierung für ihr gegenwärtiges und künftiges Verhalten zu gewinnen – eine Fähigkeit, die auch vielen Lernprozessen zugrunde liegt (...) und beim Menschen für die Herausbildung eines Selbst zentral ist. Die beiden ersten Bedeutungen betreffen hingegen die kulturelle Identität von Gemeinschaften. (shrink)

The memory impairment of neurological and psychiatric patients is seen as occurring mainly in the autobiographical-episodic memory domain and this is considered to depend on limbic structures such as the amygdala or the septal nuclei. Especially the amygdala is a hub for giving an emotional flavor to personal memories. Bastin et al. fail to include the amygdala in their integrative memory model.

Autobiographical–episodic memory is the conjunction of subjective time, autonoetic consciousness and the experiencing self. Understanding the neural correlates of autobiographical–episodic memory might therefore be essential for shedding light on the neurobiology underlying the experience of being an autonoetic self. In this contribution we illustrate the intimate relationship between autobiographical–episodic memory and self by reviewing the clinical and neuropsychological features and brain functional imaging correlates of psychogenic amnesia – a condition that is usually characterized by severely impaired retrograde memory functioning, in (...) absence of structural brain damage as detected by standard imaging. We demonstrate that in this disorder the autobiographical–episodic memory deficits do not exist in isolation, but occur with impairments of the autonoetic self-consciousness, emotional processing, and theory of mind or executive functions. Furthermore functional and metabolic brain alterations involving regions that are agreed upon to exert crucial roles in memory processes were frequently found to accompany the psychogenic memory “loss”.

The article develops a theoretical framework that is capable of integrating the biological foundations of emotions with their cultural and semantic formation.

We addressed the questions whether stimuli presented below the threshold of verbal awareness are nevertheless perceived and whether there are perceptual differences between the two cerebral hemispheres. Pictures of line drawn objects and animals were subliminally presented to each visual half-field for subsequent identification in a form as fragmented as possible. The performance of 40 healthy subjects was compared to that of 63 controls. Whereas identification performance after blank presentation in the experimental group did not differ from that of controls, (...) identification in a significantly more fragmented form was achieved after the presentation of the complete picture. This effect, however, occurred only after subliminal stimulation in the left visual field, i.e., of the right hemisphere. Our results show that pictures presented below the threshold of verbal awareness can be perceived, and that only the right hemisphere can perceive them and make use of the perception. It remains an open question whether this kind of hemispheric specialization represents a right hemisphere dominance for subliminal perception or reflects an inability of the left hemisphere to access and behaviorally use unaware percepts via fragmented picture identification, for which a right hemisphere advantage is known.

Lindquist et al. remark that not all fear instances lead to heightened amygdalar activity and, instead, point to roles of the amygdala in detecting or stimuli. By reviewing research on the amygdala's functions in episodic-autobiographical memory, we further emphasize the involvement of the amygdala in coding the subjective relevance and extracting the biological and social significance of the stimuli.

We argue that repression is primarily an unconscious process and that the position of Erdelyi is not coherent with Freud's views on the matter. Repression of ideas is a process that takes place without the knowledge of the subject. In this respect, it is essentially different from suppression, where ideas are acted upon by a conscious will.

The student of philosophy usually is not irritated by obscure formulations. On the contrary, reading the quoted passage he would presumably be convinced ...

Change, Choice and Inference develops logical theories that are necessary both for the understanding of adaptable human reasoning and for the design of intelligent systems. The book shows that reasoning processes - the drawing on inferences and changing one's beliefs - can be viewed as belonging to the realm of practical reason by embedding logical theories into the broader context of the theory of rational choice. The book unifies lively and significant strands of research in logic, philosophy, economics and artificial (...) intelligence. It elaborates on the relevant theories and provides a mathematically precise foundation for the thesis that large parts of theoretical reason can be subsumed under practical reason. (shrink)

In this major work, Blumenberg takes issue with Karl Lowith's well-known thesis that the idea of progress is a secularized version of Christian eschatology, which promises a dramatic intervention that will consummate the history of the ...

This lucid and accessible dictionary presents technical terms that Wittgenstein introduced into philosophical debate or transformed substantially, and also topics to which he made a substantial contribution. Hans-Johann Glock places Wittgenstein's ideas in their historical context, and indicates their impact on his contemporaries as well as their relevance to current debates. The entries delineate Wittgenstein's lines of argument on particular issues, assessing their strengths and weaknesses, and shed light on fundamental exegetical controversies. The dictionary entries are prefaced by a (...) ‘Sketch of an Intellectual Biography’, which links the basic themes of the early and later philosophy and describes the general development of Wittgenstein's thinking. Extensive textual references, a detailed index and an annotated bibliography will facilitate further study. Authoritative, comprehensive and clear, the volume will be welcomed by anyone with an interest in Wittgenstein – his life, work or influence. Each Blackwell Philosopher Dictionary presents the life and work of an individual philosopher in a scholarly but accessible manner. Entries cover key ideas and thoughts, as well as the main themes of the philosopher's works. A comprehensive biographical sketch is also included. (shrink)

What role do metaphors play in philosophical language? Are they impediments to clear thinking that should be eradicated in the interests of terminological exactness? Or can they be used by philosophers to indicate the attitudes that regulate an epoch?

Machines will attain human levels of intelligence by the year 2040, predicts robotics expert Hans Moravec. And by 2050, they will have far surpassed us. In this mind-bending new book, Hans Moravec takes the reader on a roller coaster ride packed with such startling predictions. He tells us, for instance, that in the not-too-distant future, an army of robots will displace workers, causing massive, unprecedented unemployment. But then, says Moravec, a period of very comfortable existence will follow, as (...) humans benefit from a fully automated economy. And eventually, as machines evolve far beyond humanity, robots will supplant us. But if Moravec predicts the end of the domination by human beings, his is not a bleak vision. Far from railing against a future in which machines rule the world, Moravec embraces it, taking the startling view that intelligent robots will actually be our evolutionary heirs. "Intelligent machines, which will grow from us, learn our skills, and share our goals and values, can be viewed as children of our minds." And since they are our children, we will want them to outdistance us. In fact, in a bid for immortality, many of our descendants will choose to transform into "ex humans," as they upload themselves into advanced computers. We will become our children and live forever. In his provocative new book, the highly anticipated follow-up to his bestselling volume Mind Children, Moravec charts the trajectory of robotics in breathtaking detail. A must read for artificial intelligence, technology, and computer enthusiasts, Moravec's freewheeling but informed speculations present a future far different than we ever dared imagine. (shrink)

Hij buigt zich over de notie van seksuele authenticiteit en lanceert ten slotte ook een oproep (...) voor betere pornografie. (shrink)

Analytic philosophy is roughly a hundred years old, and it is now the dominant force within Western philosophy. Interest in its historical development is increasing, but there has hitherto been no sustained attempt to elucidate what it currently amounts to, and how it differs from so-called 'continental' philosophy. In this rich and wide-ranging book, Hans Johann Glock argues that analytic philosophy is a loose movement held together both by ties of influence and by various 'family resemblances'. He considers the (...) pros and cons of various definitions of analytic philosophy, and tackles the methodological, historiographical and philosophical issues raised by such definitions. Finally, he explores the wider intellectual and cultural implications of the notorious divide between analytic and continental philosophy. His book is an invaluable guide for anyone seeking to understand analytic philosophy and how it is practised. (shrink)

The paper attacks the widely held view that belief revision theories, as they have been studied in the past two decades, are founded on the Principle of Informational Economy. The principle comes in two versions. According to the first, an agent should, when accepting a new piece of information, aim at a minimal change of his previously held beliefs. If there are different ways to effect the belief change, then the agent should, according to he second version, give up those (...) beliefs that are least entrenched. Although widely proclaimed by belief revision theorists, I argue that both versions of the principle are dogmas that are not (and perhaps should not be) adhered to. I substantiate this claim with two simple mathematical observations, and I defend it against four possible objections that involve contractions, reconstructions, dispositions, and truths. (shrink)
