Our primary goal was to develop and validate a task that could provide evidence about how humans learn praxis gestures, such as those involving the use of tools. To that end, we created a video-based task in which subjects view a model performing novel, meaningless one-handed actions with kinematics similar to praxis gestures. Subjects then imitated the movements with their right hand. Trials were repeated 6 times to examine practice effects. EEG was recorded during the task. As a control, subjects (...) watched videos of a model performing a well-established (over learned) tool-use gesture. These gestures were also imitated 6 times. Demonstrating convergent validity, EEG measures of task-related cortical activation were similar in topography and frequency between the novel gesture task and the overlearned, praxis gesture task. As in studies assessing motor skill learning with simpler tasks, cortical activation during novel gesture learning decreased as the same gestures were repeated. In the control condition, repetition of overlearned tool-use gestures were also associated with reductions in activation, though to a lesser degree. Given that even overlearned, praxis gestures show constriction of EEG activity with repetition, it is possible that that attentional effects drive some of the repetition effects seen in EEG measures of activation during novel gesture repetition.

Autism spectrum disorders (ASD) are thought to result in part from altered cortical excitatory-inhibitory balance; this pathophysiology may impact the generation of oscillations on EEG. We investigated premotor-parietal cortical physiology associated with praxis, which has strong theoretical and empirical associations with ASD symptomatology. 25 children with high-functioning ASD (HFA) and 33 controls performed a praxis task involving the pantomiming of tool use, while EEG was recorded. We assessed task-related modulation of signal power in alpha and beta frequency bands. Compared with (...) controls, subjects with HFA showed 27% less left central (motor/premotor) beta (18-22 Hz) event-related desynchronization (ERD) (p = 0.030), as well as 24% less left parietal alpha (7-13 Hz) ERD (p = 0.046). Within the HFA group, blunting of central ERD attenuation was associated with impairments in clinical measures of praxis imitation (r = -0.4; p = 0.04) and increased autism severity (r = 0.48; p = 0.016). The modulation of central beta activity is associated, among other things, with motor imagery, which may be necessary for imitation. Impaired imitation has been associated with core features of ASD. Altered modulation of oscillatory activity may be mechanistically involved in those aspects of motor network function that relate to the core symptoms of ASD. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 35.3 (2002) 223-243 [Access article in PDF] Style, Rhetoric, and Postmodern Culture Bradford Vivian Modern rhetoricians habitually avoid the canon of style. The reasons for this avoidance should be familiar to those versed in the disciplinary lore of rhetoric. Since the fifth and fourth centuries B. C. E., when oratorical virtuosos like Gorgias proclaimed that "Speech is a powerful lord, which by means of the finest (...) and most invisible body effects the divinest works" (41), the suspicion that rhetorical style amounts to irrational verbal excess has dogged those who would argue for the moral integrity of the art. Most recently, twentieth-century rhetoricians, Toulmin (1958) and Perelman (1969, 1979, 1982) in particular, realigned rhetoric with the study of argumentation after its apparent reduction, during the eighteenth and nineteenth centuries, to innocuous matters of form and taste by the elocutionist and belletristic movements. Consequently, the aesthetic capacities of rhetoric have received scant attention from modern rhetoricians, who resign considerations of style largely to supposedly regrettable episodes in the history of the discipline. For better or worse, then, modern rhetorical theory lacks a contemporary rationale and methodology for the study of style. 1Beyond unfortunate equations of rhetoric with grandiloquence, this scarcity in recent rhetorical scholarship corresponds to general humanistic and social scientific prejudices against the topic of style. Robert Hariman posits, "Established academic conceptions of style hardly prepare one to take seriously the aesthetic dimension of political experience" (7). As evidence for this claim, he cites Stuart Ewen's reflections on the "frustration" peculiar to research on style: "It seemed to be a universal category," Ewen writes, "transcending topical boundaries, an accolade applied to people, places, attitudes and things... a subject that was, at best, amorphous" (quoted in Hariman, 7-8). Yet the social ubiquity of style—"[o]n news magazines, sports magazines, music-oriented magazines, magazines about [End Page 223] fashion, architecture and interior design, automobiles, and sex"—indicates that it offers "a key to understanding the contours of contemporary culture" (qtd. in Hariman, 7-8). Hence, the paradox of style as a scholarly topic: that which exhibits its cultural importance makes it seem intellectually vacuous.Hariman's treatise on political style offers the most noteworthy attempt in rhetorical studies to remedy these trends; brief consideration of his insights will suggest further objectives for the study of rhetoric and style. 2 In Hariman's estimation, "style ultimately is a significant dimension of every human experience" because "relations of control and autonomy are negotiated through the artful composition of speech, gesture, ornament, decor, and any other means for modulating perception and shaping response. In a word, our political experience is styled" (3, 2). The distinctive contribution of rhetorical inquiry into political style involves "understanding the dynamics of our social experience or the relationship between rhetorical appeals and political decisions" rather than merely "cataloging discursive forms in the artistic text alone" (Hariman, 8).Accordingly, Hariman acknowledges that one must recognize the substantive social and political influences of style apart from its traditional connotations of individual artistic performance. "In this context," he explains, "although style still highlights aesthetic reactions it no longer enforces artistic autonomy. Style becomes an analytic category for understanding a social reality; in order to understand the social reality of politics, we can consider how political action involves acting according to a particular political style" (9). Thus, for Hariman, rhetorical choices in political style need not amount to a valorization of "artistic autonomy": "each political style draws on universal elements of the human condition and symbolic repertoire but organizes them into a limited, customary set of communicative designs... Each is thoroughly conventional, yet the means for personal improvisation and intelligent, innovate responses to unique problems" (11-12). His treatise therefore appears to dissociate style from its outmoded definitions while recommending the utility of rhetorical principles to the study of political culture.What Hariman calls the "cautious postmodernism" (6) of his project, however, hinders its innovative aspirations. The postmodern portion of his work endorses the study of style according to the aesthetic dimensions of social relations rather than "artistic autonomy" alone; but its... (shrink)

David Ricardo was a hugely influential British political economist and stock trader. This volume, first published in 1923, contains five important pamphlets published by him, edited and with an overarching introductory essay by E. C. K. Gonner. Each essay relates either to monetary and financial subjects - including the high price of Bullion, monetary theory and the position of the Bank of England - or to the agricultural conditions of Britain and proposed solutions to the problems discussed. This is a (...) fascinating and detailed work, which will be of great value to those with an interest in Ricardo’s theories and British economic history. (shrink)

L'incommensurable fait apparaître qu'il est des fêlures irréductibles dans notre expérience révélant de l'infini du sein même de cette expérience: entre le plaisir et la jouissance ou bien le rapport social et l'intime. L'inouï dit, non pas l'extraordinaire ou l'insolite, mais ce qui peut être au contraire le plus commun de notre expérience--mais que nous n'entendons pas parce que nous ne savons pas déborder les cadres figés de cette expérience. La vraie vie fait signe vers ce que, tout en étant (...) en vie, nous risquons de n'être toujours que dans une apparence de vie, ou pseudo-vie, sans accéder à vraiment vivre.

Contre les facilités du prêche et du marché du Bonheur, il faut penser ces concepts comme outils pour 'changer la vie.'"--Page 4 of cover. (shrink)

E. Rae Harcum argues that Christians do not have to give up their religious faith to keep the contributions of science. He confronts the relation between the human body and its non-material parts—the mind and spirit—and provides a way of looking at these metaphysical issues.

How should pragmatists respond to and contribute to the resolution of one of America's greatest and most enduring problems? Given that the most important thinkers of the pragmatist movement—Charles S. Peirce, William James, John Dewey, and George Herbert Mead—said little about the problem of race, how does their distinctly American way of thinking confront the hardship and brutality that characterizes the experience of many African Americans in this country? In 12 thoughtful and provocative essays, contemporary American pragmatists connect ideas with (...) action and theory with practice to come to terms with this seemingly intractable problem. Exploring themes such as racism and social change, the value of the concept of race, the role of education in ameliorating racism, and the place of democracy in dealing with the tragedy of race, the voices gathered in this volume consider how pragmatism can focus new attention on the problem of race. Contributors are Michael Eldridge, Eddie S. Glaude, Jr., Judith M. Green, D. Micah Hester, Donald F. Koch, Bill E. Lawson, David E. McClean, Gregory F. Pappas, Scott L. Pratt, Alfred E. Prettyman, John R. Shook, Paul C. Taylor, and Cornel West. (shrink)

Part two of the proceedings of the fifth International Congress of Logic, Methodology and Philosophy of Science, London, Ontario, Canada, August 27 - September 2, 1975.

Ecclesia and Ethics considers the subject of Ecclesial Ethics within its theological, theoretical and exegetical contexts. Part one presents the biblical-theological foundations of an ecclesial ethic – examining issues such as creation, and Paul's theology of the Cross. Part two moves on to examine issues of character formation and community. Finally, part three presents a range of exegetical applications, which examine scripture and ethics in praxis. These essays look at hot-button issues such as the 'virtual self' in the digital age, (...) economics, and attitudes to war. The collection includes luminaries such as N.T. Wright, Michael J. Gorman, Stanley Hauerwas and Dennis Hollinger, as well as giving space to new theological and exegetical voices. As such Ecclesia and Ethics provides a challenging and contemporary examination of modern ethical debates in the light of up-to-date theology and exegesis. (shrink)
