Variable responses to transcranial direct current stimulation protocols across individuals are widely reported, but the reasons behind this variation are unclear. This includes tDCS protocols meant to improve attention. Attentional control is impacted by top-down and bottom-up processes, and this relationship is affected by state characteristics such as anxiety. According to Attentional Control Theory, anxiety biases attention towards bottom-up and stimulus-driven processing. The goal of this study was to explore the extent to which differences in state anxiety and related measures (...) affect visual attention and category learning, both with and without the influence of tDCS. Using discovery learning, participants were trained to classify pictures of European streets into two categories while receiving 30 min of 2.0 mA anodal, cathodal, or sham tDCS over the rVLPFC. The pictures were classifiable according to two separate rules, one stimulus and one hypothesis-driven. The Remote Associates Test, Profile of Mood States, and Attention Networks Task were used to understand the effects of individual differences at baseline on subsequent tDCS-mediated learning. Multinomial logistic regression was fit to predict rule learning based on the baseline measures, with subjects classified according to whether they used the stimulus-driven or hypothesis-driven rule to classify the pictures. The overall model showed a classification accuracy of 74.1%. The type of tDCS stimulation applied, attentional orienting score, and self-reported mood were significant predictors of different categories of rule learning. These results indicate that anxiety can influence the quality of subjects’ attention at the onset of the task and that these attentional differences can influence tDCS-mediated category learning during the rapid assessment of visual scenes. These findings have implications for understanding the complex interactions that give rise to the variability in response to tDCS. (shrink)

In the poem which sets the seal on his three books of odes, Horace declares that his monument to himself will be more durable than bronze and higher than the pyramids. As T. E.

This is a confusing attempt to reconcile realist philosophy with an aesthetic stand. The book includes a discussion of the contributions of artists, philosophers, and critics to the formulation of an aesthetic viewpoint; a brief history of idealistic aesthetic theory embodied in the ideas of Kant, Hegel, Croce, and Tolstoy; a definition and defense of "excellence" as the criterion in the evaluation of art; and a justification for the continued inclusion of aesthetics as a philosophical endeavor. Realists, with their emphasis (...) on the scientific approach, verification, and measurement have always had a certain amount of understandable trouble with the arts, a field known for its fluidity and willful perversity regarding attempts to establish permanent, stable criteria of evaluation. Gibson draws heavily on Wittgenstein's idea of "family resemblances" and Weitz's application of that idea to art. In doing so, however, he ignores Weitz's warning that since art has no set of necessary properties and since, therefore, it is impossible to formulate theoretical definitions of it, aestheticians might better spend their time on other issues. Gibson builds his case around a family resemblance of various, so-called permanent excellences such as "significant form," "expressiveness," and "communicative efficacy" which, he insists, just happen to converge together in "great" works of art. With this statement, as well as others concerning the effect great art must produce in the beholder, Gibson has returned to the idea of an Absolute definition which, though pluralistic in scope, is still as rigid, exclusive, and closed a concept as the ones he denounces, despite his statements of "proof" to the contrary. Mention should also be made of the weakness of the overall structure of the book. Ideas and explanations become confusing when they are dropped in driblets throughout diverse chapters. This book adds nothing to the ideas of Wittgenstein or Weitz while, at the same time, detracting considerably from the clarity and logic of their concepts.--B. T. (shrink)

This work explores an aspect of Yeats's writing largely ignored until now: namely, his wide-ranging absorption in S.T. Coleridge. Gibson explores the consistent and densely woven allusions to Coleridge in Yeats's prose and poetry, often in conjunction with other Romantic figures, arguing that the earlier poet provided him with both a model of philosopher - 'the sage' - and an interpretation of metaphysical ideas which were to have a resounding effect on his later poetry, and upon his rewriting of (...)

Most debate about the ethical implications of modern biotechnology has centred around medical issues, but public concerns over the impact of agricultural biotechnologies have gathered momentum. This volume, resulting from the 55th University of Nottingham Easter School in Agricultural and Food Science, provides a survey of this new field of enquiry. The book will be of interest to a wide readership, including applied philosophers, sociologists, economists and ecologists, as well as biotechnologists and agricultural and food scientists.

Greek art and literature follow parallel courses through the long period from Homer to Euripides. Homer and Euripides, Dipylon vases and the latest white lekythoi are as far apart from each other as it is possible for works in the same medium to be. The distance can only be explained by a similar change in the views of artists, writers, and their public.

This collection of essays addresses some of the central issues in modern social and political thought, such as: the revival of Marxism and its relevance to the social sciences; the analysis of social and political structures and social movements; and the future of advanced capitalist societies.

Marx was barely 25 when he produced this astonishing rich body of work-including economic and Philosophical Manuscripts and On the Jewish Question.

In The Theatre of Dionysus in Athens Dr. Pickard-Cambridge includes a most useful and convenient collection of south Italian vase-paintings which have been held to throw light on the stage-settings of Greek tragedy. He concludes that they give no evidence for Athens in the fifth century and in particular do not justify the assumption that interior scenes were played in a porch in front of the central door. The second conclusion is true, but some of the vases do show that (...) the central doors could be thrown wide open to display an interior scene. The first conclusion is formally correct, but it should be remembered that the “plays came from Athens, and it is at least possible that the south Italian producers modelled themselves on Athenian producers. In any case these vases are worthy of further consideration. (shrink)

The comic is one of the principal esthetic categories; it unites the multifaceted experience of the social mind as it assimilates and cognizes the world, particularly the social world, on the basis of axioms of common sense, or even of public opinion about these axioms. Boldly violating the laws of logic and the verisimilitude of images, of normal connections and notions, and playing upon these violations, the comic nonetheless remains firmly on the side of common sense. The comic is inexhaustible (...) in its nuances — from light merriment and entertainment to malicious ridicule and satire, from gross farce to subtle forms of irony and humor. (shrink)
