Human vision supports prediction for moving stimuli. Here we take an individual differences approach to investigate whether there could be a common processing rate for motion-based visual prediction across diverse motion phenomena. Motion Induced Spatial Conflict refers to an incongruity arising from two edges of a combined stimulus, moving rigidly, but with different apparent speeds. This discrepancy induces an illusory jitter that has been attributed to conflict within a motion prediction mechanism. Its apparent frequency has been shown to correlate with (...) the frequency of alpha oscillations in the brain. We asked what other psychophysical measures might correlate positively with MISC frequency. We measured the correlation between MISC jitter frequency and another three measures that might be linked to motion-based spatial prediction. We demonstrate that the illusory jitter frequency in MISC correlates significantly with the accrual rate of the Motion Induced Position Shift effect - the well-established observation that a carrier movement in a static envelope of a Gabor target leads to an apparent position shift of the envelope in the direction of motion. We did not observe significant correlations with the other two measures – the Adaptation Induced Spatial Shift accrual rate and the Smooth Motion Threshold. These results suggest a shared perceptual rate between MISC and MIPS, implying a common periodic mechanism for motion-based visual prediction. (shrink)

Nicolas Coldstream was a tall but not lofty person. His manner indeed was that of a quiet and thoughtful member of the old-school type, and this certainly was occasionally misinterpreted. Coldstream tended to couch his disagreements in terms well known from the Yes Minister repertoire: ‘I am not quite sure that I can follow you completely on that’. His deliberate and seemingly at times slow responses were however always to the point, and couched in readily understandable terms; his students always (...) valued the meticulous detail that he could bring to their work, as he did in his publications. Academically Coldstream concentrated on the essentials of gathering physical evidence and interpreting them in historical terms, be they art-historical or broadly political. He regarded both his basic books, Greek Geometric Pottery: a Survey of Ten Local Styles and their Chronology and Geometric Greece as historical contributions; certainly nobody working in the field can afford to ignore either.

Faces carry key personal information about individuals, including cues to their identity, social traits, and emotional state. Much research to date has employed static images of faces taken under tightly controlled conditions yet faces in the real world are dynamic and experienced under ambient conditions. A common approach to studying key dimensions of facial variation is the use of facial caricatures. However, such techniques have again typically relied on static images, and the few examples of dynamic caricatures have relied on (...) animating graphical head models. Here, we present a principal component analysis -based active appearance model for capturing patterns of spatiotemporal variation in videos of natural dynamic facial behaviours. We demonstrate how this technique can be applied to generate dynamic anti-caricatures of biological motion patterns in facial behaviours. This technique could be extended to caricaturing other facial dimensions, or to more general analyses of spatiotemporal variations in dynamic faces. (shrink)

This article presents a case study of life and work at the Royal Observatory at Greenwich which reveals tensions between the lived reality of the observatory as a social space, and the attempts to create order, maintain discipline and project an image of authority in order to ensure the observatory's long-term stability. Domestic, social and scientific activities all intermingled within the observatory walls in ways which were occasionally disorderly. But life at Greenwich was carefully managed to stave off such disorder (...) and to maintain an appearance of respectability which was essential to the observatory's reputation and output. The article focuses on three areas of management: the observatory's outer boundaries, demonstrating how Greenwich navigated both human and environmental intrusions from the wider world; the house, examining how Greenwich's domestic spaces provided stability, while also complicating observatory life via the management of domestic servants; and the scientific spaces, with an emphasis on the work and play of the observatory's boy computers. Together, these three parts demonstrate that the stability of the observatory was insecure, despite being perpetuated via powerful physical and social boundaries. It had to be continually maintained, and was regularly challenged by Greenwich's occupants and neighbours. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.4 (2000) 319-335 [Access article in PDF] Rhetoric as a Technique and a Mode of Truth: Reflections on Chaïm Perelman Alan Gross In memoriam: Henry Johnstone, fons et origo.In one of his many criticisms of The New Rhetoric, the philosopher Henry W. Johnstone Jr. complains about its chapter "The Dissociation of Concepts" that "one is never sure whether [Chaïm Perelman is] thinking of rhetoric primarily (...) as a technique or primarily as a mode of truth. One wonders, too, what status [he is] claiming for the book itself" (1978, 99). 1 Since the chapter in question largely concerns philosophical argument, the doubt is very much apropos. But the response to Johnstone's implied question--a response that Johnstone does not think available--is that the correct answer legitimately varies in a systematic way. While in philosophical contexts, and, incidentally, in scientific ones, rhetoric is invariably a mode of truth, in contexts of public address it need not be. To see how this systematic variation might be the case, I will focus, as does Johnstone, on the dissociation of concepts as a test case of the robustness of a rhetoric oriented toward truth. To do so, I must first define dissociation and then come to terms with the way in which concepts are dissociated in public address, in philosophy, and in science. In treating these examples, however, I must be wary. While they will vary systematically according to field, they are not each instances of any general "law" of dissociation. Johnstone is surely right to "doubt whether there is any general logic of dissociation; there is only the logic of each particular dissociation, generated in each case by a particular problem" (99). When I have run through my examples, I can return to Johnstone's question about the status of rhetoric and of Perelman's study of it.Suppose that, in a campaign for the United States Senate, my opponent says that the central issue is high taxes, not the rise of medical costs, while I say that the central issue is medical costs, not high taxes. Neither of us [End Page 319] need be engaged in the dissociation of concepts; we may simply be excluding taxes and medical care, respectively, from political matters that deserve our immediate and full attention; we may simply be breaking the link between these issues and those of high political salience. In Perelman's words, "[T]he technique of breaking up a liaison consists... in asserting that elements that should remain separated and independent are improperly associated" (Perelman and Olbrechts-Tyteca 1969, 411). Yet, if we think that adequate medical care for all Americans is a moral issue, that it transcends politics, we are dissociating this issue from the category of campaign issues of the ordinary sort, those that deal "merely" with expediency. In the process, we are devaluing matters of mere expediency. Dissociation is a way of taking the argumentative high ground, of putting an issue on a different plane, an act that in this case turns a political race into a moral contest. In Perelman's words, "[T]he dissociation of notions brings about a more or less profound change in the conceptual data that are used as a basis of argument. It is then no more a question of breaking the links that join independent elements, but of modifying the very structure of these elements" (412).To illustrate this difference, I will use two parallel passages on the same topic: one from Stephen Douglas and the other from Abraham Lincoln, both from the debate between them in Alton, Illinois, on 15 October 1858. In his passage, Douglas stoutly defends states' rights: This government was made on the great basis of the sovereignty of the States--the right of each state to regulate its own domestic institutions to suit itself, and that right was conferred with the understanding and expectation that inasmuch as each locality had separate and distinct interests, each state must have different and distinct local and domestic institutions, corresponding to the wants...

Review of Aesthetics of Religion: A Connective Concept, eds. Alexandra Grieser and Jay Johnston, Religion and Reason, 58.

A textbook for the undergraduate who is meeting the Lebesgue integral for the first time, relating it to the calculus and exploring its properties before deducing the consequent notions of measurable functions and measure.

Alan Sidelle's Necessity, Essence, and Individuation is a sustained defense of empiricism—or, more generally, conventionalism—against recent attacks by realists. Sidelle focuses his attention on necessity a posteriori, a kind of necessity which contemporary realists have taken to support realism over empiricism. Turning the tables against the realists, Sidelle argues that if there are in fact truths necessary a posteriori, it is not realism, but rather empiricism which provides the best explanation for them.

A centipede can walk until it thinks about howit does so. Thereafter it stumbles, over thesheer impossibility of the information andcoordination required. Life in the economy islittle different. Those engaged in productionand exchange discover, pragmatically, ways tomake them work. Those observing the processsee, realistically, the immense improbabilitythat it should do so. That most economies workin practice, but must pass such toughteleological tests to succeed in theory,highlights a difference between players' andspectators' outlook which may help to explainwhy the game has repeatedly (...) been thrown wideopen just when conclusive results seemed withinreach.Section 1 of this paper identifies the fourforms of realism which economists have tendedto adopt. Section 2 considers the pragmatism ofeconomic agents, when observed in action bypsychologists and management scholars notoverly steeped in economic theory. Theconcluding section reviews the ways in whicheconomists have tried to blur the distinction,by reclassifying agents as realistic or theirown views as pragmatic, and suggests that amore pragmatic economics might bridge thedivide.

The first book length study of property-owning democracy, Republic of Equals argues that a society in which capital is universally accessible to all citizens is uniquely placed to meet the demands of justice. Arguing from a basis in liberal-republican principles, this expanded conception of the economic structure of society contextualizes the market to make its transactions fair. The author shows that a property-owning democracy structures economic incentives such that the domination of one agent by another in the market is structurally (...) impossible. The result is a renovated form of capitalism in which the free market is no longer a threat to social democratic values, but is potentially convergent with them. It is argued that a property-owning democracy has advantages that give it priority over rival forms of social organization such as welfare state capitalism and market socialist institutions. The book also addresses the currently high levels of inequality in the societies of the developed West to suggest a range of policies that target the "New Inequality" of our times. For this reason, the work engages not only with political philosophers such as John Rawls, Philip Pettit and John Tomasi, but also with the work of economists and historians such as Anthony B. Atkinson, François Bourguignon, Jacob S. Hacker, Lane Kenworthy, and Thomas Piketty. (shrink)

Alan Millar examines our understanding of why people think and act as they do. His key theme is that normative considerations form an indispensable part of the explanatory framework which we use to understand each other. Millar offers illuminating discussions of reasons for belief and reasons for action, the explanation of beliefs and actions in terms of the subject's reasons, the idea that simulation has a key role in understanding people, and the limits of explanation in terms of propositional (...) attitudes.

Alan Miller offers a focused account of perceptual knowledge, the knowledge that we gain by means of seeing, hearing, feeling, smelling, and tasting. He explains perceptual knowledge in terms of general recognitional abilities, then situates that account within a broader perspective on epistemology and philosophical method more generally.

Despite immediate appearances, this book is not primarily a hermeneutical exercise in which the superiority of one interpretation of canonical texts is championed against others. Its origin lies elsewhere, near the overlap of history, psychoanalysis, aesthetics, and social theory of the usual kind. Weber, Pareto, Freud, W. I. Thomas, Max Scheler, Karl Mannheim, and many others of similar stature long ago wondered and wrote much about the interplay between societal rationalization and individual rationality, between collective furor and private psychopathology—in short, (...) about the strange and worrisome union of “character and social structure” (to recall Gerth and Mills). Pondering the history of social thought in this century can lead to the unpleasant realization that such large-scale questions slipped away, especially from sociologists, sometime before World War II. Or, if not entirely lost, they were so transformed in range and rhetoric that a gap opened between contemporary theorizing and its European background. Perhaps this partly explains Weber’s continuing appeal. By dealing with him, one might again broach topics long at odds with “social science” of the last forty years.—From the Preface. (shrink)

In this book, Mark Johnston argues that God needs to be saved not only from the distortions of the "undergraduate atheists" but, more importantly, from the idolatrous tendencies of religion itself. Each monotheistic religion has its characteristic ways of domesticating True Divinity, of taming God's demands so that they do not radically threaten our self-love and false righteousness. Turning the monotheistic critique of idolatry on the monotheisms themselves, Johnston shows that much in these traditions must be condemned as (...) false and spiritually debilitating. A central claim of the book is that supernaturalism is idolatry. If this is right, everything changes; we cannot place our salvation in jeopardy by tying it essentially to the supernatural cosmologies of the ancient Near East. Remarkably, Johnston rehabilitates the ideas of the Fall and of salvation within a naturalistic framework; he then presents a conception of God that both resists idolatry and is wholly consistent with the deliverances of the natural sciences. Princeton University Press is publishing Saving God in conjunction with Johnston's forthcoming book Surviving Death, which takes up the crux of supernaturalist belief, namely, the belief in life after death.

Knowledge of the ethical and legal basis of medicine is as essential to clinical practice as an understanding of basic medical sciences. In the UK, the General Medical Council requires that medical graduates behave according to ethical and legal principles and must know about and comply with the GMC’s ethical guidance and standards. We suggest that these standards can only be achieved when the teaching and learning of medical ethics, law and professionalism are fundamental to, and thoroughly integrated both vertically (...) and horizontally throughout, the curricula of all medical schools as a shared obligation of all teachers. The GMC also requires that each medical school provides adequate teaching time and resources to achieve the above. We reiterate that the adequate provision and coordination of teaching and learning of ethics and law requires at least one full-time senior academic in ethics and law with relevant professional and academic expertise. In this paper we set out an updated indicative core content of learning for medical ethics and law in UK medical schools and describe its origins and the consultative process by which it was achieved.

Critical insights into Kierkegaard's influence on Barth's theology. Karl Barth was often critical of Søren Kierkegaard's ideas as he understood them. But close reading of the two corpora reveals that Barth owes a lot to the melancholy Dane. Both conceive of God as infinitely qualitatively different from humans, and both emphasize the shocking nearness of God in the incarnation. As public intellectuals, they used this theological vision to protect Christocentric faith from political manipulation and compromise. For Kierkegaard, this meant criticizing (...) the state church; for Barth, this entailed resisting Nazism. Meticulously crafted by a father-son team of renowned systematic theologians, Beyond Immanence demonstrates that Kierkegaard and Barth share a theological trajectory--one that resists cynical manipulation of Christianity for political purposes in favor of uncompromising devotion to a God who is radically transcendent yet established kinship with humanity in time.

Attending to the Literary: The Distinctiveness of Literature is a foray into current debates about the nature of the literary. What is literary? Is literarity a thing? Are there still aesthetic standards of taste? Is the category of literary aesthetics an obstacle to understanding the uses of literature? What does it mean to count the reading of literature as an experience in its own right? What would be the deficits to human experience without literature? Attending to the Literary addresses all (...) of these questions with a view to challenging the notion of literarity as merely representative of experience. On the contrary, Alan Singer shows how literarity is an enacting of experience. Through close readings of an eclectic repertoire of literary sentences-culled from the genres of fiction, poetry and drama--Singer demonstrates how syntax stages human capacities for attending ever more consequentially to the world of practical experience. These stagings of forms of attention involve readers in the drama of reason giving and expand the possibilities of rational imagination. Attending to the Literary speaks to a broad audience of readers for whom the question "Why literature matters?" remains an urgent intellectual challenge. (shrink)

The idea of the inner is central to our conception of a person and is at the heart of all interaction. But how should we understand this concept, and what do we mean when we wonder what is going on inside our heads? This accessible and non-technical guide to Wittgenstein provides insight into his work in this area and on the problem of the inner. Using Wittgenstein's recently published writings on the philosophy of psychology, together with unpublished material, Paul (...) class='Hi'>Johnston presents a thorough account of a subject that was central to Wittgenstein's later work. He shows that Wittgenstein's arguments involve a radical re-thinking of our understanding of the inner and present a challenge to contemporary views which has yet to be fully appreciated or understood. Wittgenstein demonstrates how a Wittgensteinian approach can dissolve age-old problems about the nature of consciousness and the relationship between the mind, the body, and the soul. The resulting picture of the inner, with its stress on the crucial role of language, sheds light on the direction of Wittgenstein's work and presents a stimulating and controversial alternative to more fashionable positions on the subject.
