Imbalanced plasticity of neural networks in the brain is proposed to underlie deficits in the integration of efferent and afferent processes in schizophrenia. These deficits affect the priming of the behavior implementing systems by prior knowledge, and thus impair both controlled regulation and automatic activation of mental and motor processes. The sense of self as a distinct entity can consequently be undermined. In predominantly reality-distorting patients, hypo-plasticity of neural connectivity may cause the emergence of highly focused but inflexible patterns of (...) activation in their representation and response systems. This may lead to dominance of prepotent patterns of activity in these systems and a relative inability of higher control systems to bias lower level activity towards congruence with the ongoing cognitive and motor context. By contrast, predominantly disorganized patients are characterized by hyper-plastic connectivity. This leads to a weakening of prepotent response tendencies but also, as in reality-distorting patients, to less effective top-down contextual constraining. (shrink)

In a recent study half of the participants were informed of the occasional occurrence of location regularities in visual stimulus sets, while the other half was not. Evidence was presented to the effect that uninformed participants extracted the patterns from the displays better than the informed participants. The authors interpret their finding as demonstrating that working memory can operate non-consciously. However, inspection of the data suggests that rather than being more effective than the informed participants in extracting patterns, uninformed participants (...) were more strongly affected by the “Broken Patterns” that served as misleading cues. Thus whereas the findings may support the possibility of non-conscious operation of low level WM functions, they nevertheless underscore the importance of conscious awareness as far as higher level functions are concerned.

The enigmatic sixteenth-century Swiss physician and natural philosopher Philippus Aureolus Theophrastus Bombastus von Hohenheim, called Paracelsus, is known for the almost superhuman energy with which he produced his innumerable writings, for his remarkable achievements in the development of science, and for his reputation as a visionary and alchemist. Little is known of his biography beyond his legendary achievements, and the details of his life have been filled in over the centuries by his admirers. This richly illustrated anthology presents in modernized (...) language a selection of the moral thought of a man who was not only a self-willed genius charged with the dynamism of an impetuous and turbulent age but also in many ways a humble seeker after truth, who deeply influenced C. G. Jung and his followers. (shrink)

In a response to Hassin’s reply to my comment on his study ), I suggest that the involvement of the central executive reveals itself in the absence of the Pattern variable effect in the Informed group, rather than in the presence of this effect in the uninformed one.

This is an informative, well-written, spritely, and sympathetic survey of the development of Marxism in France from the late nineteenth century to Sève's An Introduction to Marxist Philosophy. Although Kelly does not characterize it this way, his work may be seen as a history of the dialectical evolution of French Marxism. By tracing the historical background of the variety of theoretical works on Marx's writings and on Marxism in general and sketching the systolic and diastolic movements of the French communist (...) party as well, Kelly has produced an indispensable propaedeutic to a deeper study of the fertile writings of the leading French Marxist thinkers. He is careful and patient as he traces the twists and turns of theoretical perspectives. The relation between Hegel and Marx is a thread which runs through his exposition. Guterman and Henri Lefebvre's attempt to analyze the nature of the dialectic and the central idea of contradiction in the 1930's is discussed clearly, with emphasis upon Lefebvre's aim of attributing a non-materialistic dialectic to Marx, of characterizing historical materialism as "the unity of idealism and materialism." Stalin's exposition of dialectical and historical materialism is shown to have inaugurated an era of dogmatic Marxism. Kelly shows us how things picked up during the post-war years and how the theoretical richness of French Marxism gained momentum up to 1980. The influence of Lefebvre's Dialectical Materialism is traced up to the early anti-Hegelian standpoint of Althusser. In a later chapter, we are offered a fairly detailed exposition and commentary on Althusser's criticism of the view that Marx inverted Hegel, his analysis of the structure of the dialectic, and his belief that the issue of the exteriority of the dialectic to its possible objects is a "question of the application of a method" which "poses a pre-dialectical question... which... has no meaning for Marx." Among other things, Kelly traces the writings of, and career of, Garaudy, discusses the innovative notion of Godelier's cybernetic dialectic, briefly sketches the contributions of Tran Duc Thao, the responses to Sartre's Critique, examines Sève's original studies of contradiction and "negation of the negation," and probably introduces most non-French readers to Jaeglé's renovation of dialectics in relation to contemporary natural science. Finally, Labica's attempt to show that philosophy is jettisoned by Marx in favor of a "science of history," D'Hondt's analyses of difference and contradiction, and Mercier-Josa's circling back through Hegel for a fresh understanding of Marx are briefly discussed. It should be said that Kelly's running commentary is always informed, judicious and independent. His work serves as an excellent introduction to modern French Marxism.--George J.

In a recent comment on our paper Implicit Working Memory Guterman argued that a possible interpretation of the results of one of our experiments is that “conscious awareness … enabled the participants to find ways to benefit from the predictability … while nullifying the cost.” Unfortunately, the data do not support this interpretation. Additionally, Guterman seems to have suggested that our results may be explained by non-working memory processes. We argue against this interpretation.
