The role of the prefrontal cortex is one of the most topical and important areas of research in contemporary neuropsychology. This cortical region appears to be linked with executive processes affecting many diverse areas of cognitive function. Working memory, information processing, behavioural organization, attention, judgement, and the ability to cope with novel experiences are just some of the diverse processes it affects. This book brings together contributions from some of the world's leading researchers on the prefrontal cortex. They discuss the (...) many recent theoretical and technical advances in the field - for example in our understanding of the neural architecture of the prefrontal cortex, in the development of comparable texts of cognition in humans and other primates, in our understanding of the relationships between neuronal activity and behaviour, and in the increasing use of functional neuroimaging to identify different levels of organization within the prefrontal cortex. These important developments make this an ideal time to address the many questions and debates that have arisen about the role and functional organization of this area of the brain. One of the first books to be written on the subject, The Prefrontal Cortex is a state-of-the-art account of our knowledge of this exciting subject. It will be welcomed by all researchers and students in neuro- and cognitive psychology, and neuroscience. (shrink)

The world appears to conscious creatures in terms of experienced sensory qualities, but science doesn't find sensory experience in that world, only physical objects and properties. I argue that the failure to locate consciousness in the world is a function of our necessarily representational relation to reality as knowers: we won't discover the terms in which reality is represented by us in the world as it appears in those terms. Qualia -- arguably a type of representational content -- will therefore (...) not be found in the physical world as characterized in experience or science. Instead, consciousness constitutes a subjective, representational reality for cognitive systems such as ourselves, and the physical world is a represented objective reality. I suggest that naturalistic approaches to explaining consciousness should acknowledge the non-objectivity of experience, and be constrained by evidence that consciousness accompanies certain sorts of behaviour-controlling representational functions carried out by complex, physically instantiated mind-systems. I evaluate a variety of current hypotheses about consciousness, and suggest that a mature science of representation may help explain why, perhaps as matter of representational necessity, experience arises as a natural but not objectively discoverable phenomenon.

Methodological disputes in economics have been with us since Mill and Senior fought over the nature of economic science in the first half of the 19th Century. Progress has been extremely slow, and there is good reason for this as the present essay hopes to show. Three important methodological positions are examined critically: the “ultra-empiricism” of T.W. Hutchison, the “moderate empiricism” of Milton Friedman, and the “extreme a priorism” of Lionel Robbins and Ludwig Von Mises. The argument between Guttierrez (...) and Block inTheory and Decision over praxiology is discussed in connection with the last mentioned position. The paper concludes that “extreme a priorism,” though very much out of fashion is not without its resources. The work of the contemporary German philosopher, Paul Lorenzen, is enlisted to bolster this position. (shrink)

Enough and too much has been written about the Epic Cycle. Upon scanty quotations and a jejune epitome a tedious literature has been built. The older writers, such as Welcker, tried to ‘reconstruct’—as profitable and satisfying a task as inferring a burnt manor-house from its cellars; later scholars have gone out in tracing the tradition of the poems through the learned age of Greece—a scaffolding without ties, by which this or that conclusion is reached according to temperamental disposition to this (...) or that fallacy. I do not intend to enter more than is needful into a controversy where so far as I can see everyone has gone beyond the evidence. If I add to the bulk of the literature, it is in the hope of putting things in their proper places and of presenting the data as they appear to a future editor. (shrink)

This essay offers a theoretical analysis of the changes which are taking place in the musical consciousness of listeners in the present phase of society. The author seeks rather to deduce the conditions of musical reception from the present stage of musical production. The first part of the article deals with changes in production as they affect the general consciousness of listeners. Light music is discussed as well as serious music insofar as it reaches the consumer. Changes in reception are (...) revealed in certain characteristics like the cult of the melody, of the voice, of the master violin, and they are tied up with specific economic concepts. Success plays a particularly important role in this connection.The second part is devoted to the retrogression in listening, analyzed psychologically. Docile passivity, imitation of pre-given patterns, and bitter resentment of the „abnormal“ have become characteristic for the listener. The author shows how this retrogression has become concretized in the formation of a „musical child’s language.“Many listeners seek to overcome passivity by a pseudo-activity. The social function of certain types like the jitter-bug, the radio amateur, or the man with a knack for jazz, are discussed.L’article entreprend d’interpréter sous forme d’une esquisse théorique les transformations qu’a subies la conscience musicale des auditeurs dans la phase actuelle de l’évolution sociale.On n’analyse pas psychologiquement les réactions des auditeurs ; mais on prend pour point de départ Tétât de la production, et de celui-ci on déduit celui de la réception.La première partie traite de la transformation de la production dans la mesure où celle-ci atteint la conscience commune des auditeurs. L’auteur considère aussi bien la musique légère que la soi-disant musique sérieuse et les modifications que connaît celle-ci pour parvenir à la consommation.Ces modifications font de la musique un fétiche. On en prend pour exemple le culte des „idées“ musicales, de la voix et des „violons de maître“. Le caractère fétiche de la musique se mesure au succès accumulé.Ensuite, on développe quelques catégories du fétichisme musical : dépravation, arrangement, „divertissement élevé“, idolâtrie de la perfection.Au fétichisme de la musique correspond du côté de l’auditeur une régression de la faculté d’entendre — phénomène qui fait l’objet de la deuxième partie de l’étude. On l’interprète comme l’attitude auditive caractéristique des „régressifs“. Soumission passive, imitation de l’antérieurement donné, fureur contre ce qui sort de la norme — définissent cette attitude, qui s’objective en un langage musical puéril en formation et dont quelques éléments sont esquissés.A cette passivité, de larges groupes d’auditeurs cherchent vainement à échapper par une pseudo-activité. Quelques types de pseudo-activité sont décrits : l’enthousiaste, le bricoleur et le „chic type“. On montre la fonction sociale de ces types.Enfin, on traite des possibilités dialectiques de l’audition du régressif. Une confrontation de l’expérience fondamentale de la musique radicalement neuve avec le mode régressif d’entendre termine l’article. (shrink)
