Attentional selection biases the processing of higher visual areas to particular parts of a scene. Recent experiments show how stimulation of neurons in the frontal eye fields can mimic this process.

What are 'emotions'? This book offers a balanced survey of facts and theory.

Why does the world look to us as it does? As Nico Orlandi argues, it is simply because of how the world is. This answer emerges from understanding vision as situated in a structured environment, and it contrasts with the view that visual perception involves an inference.

Logothetis, N.K.: Single units and conscious vision. Philosophical Transactions of the Royal Society of London Series B-Biological Sciences 353, 1801-1818 (1998) Abstract.

There is a certain excitement in vision science concerning the idea of applying the tools of bayesian decision theory to explain our perceptual capacities. Bayesian models are thought to be needed to explain how the inverse problem of perception is solved, and to rescue a certain constructivist and Kantian way of understanding the perceptual process. Anticlimactically, I argue both that bayesian outlooks do not constitute good solutions to the inverse problem, and that they are not constructivist in nature. In explaining (...) how visual systems derive a single percept from underdetermined stimulation, orthodox versions of bayesian accounts encounter a problem. The problem shows that such accounts need to be grounded in Natural Scene Statistics (NSS), an approach that takes seriously the Gibsonian insight that studying perception involves studying the statistical regularities of the environment in which we are situated. Additionally, I argue that bayesian frameworks postulate structures that hardly rescue a constructivist way of understanding perception. Except for percepts, the posits of bayesian theory are not representational in nature. bayesian perceptual inferences are not genuine inferences. They are biased processes that operate over nonrepresentational states. (shrink)

Knowledge Societies offers both a critical examination of existing social theory, and a new synthesis of social theory with the actual study of knowledge relations in advanced economies. Some of the elements explored are scientization: the penetration not only of production but of most social action by scientific knowledge; the transformation of access to knowledge through higher education; the growth of experts (managers, accountants, advisors, and counselors) and of corresponding institutions based on the deployment of specialized knowledge; and a shift (...) in the nature of societal conflict from struggles about income and property to claims and conflicts about generalized human needs. Nico Stehr's argument amply demonstrates not only that all social theories now need to take into account the changing nature of social relations around knowledge, but also the parameters within which this analysis should take place. This book is essential reading for all those interested in social theory, sociology of knowledge and science, and the general issue of knowledge in the late 20th century. (shrink)

Government authorities often view the 3Rs of “replace, reduce, refine” popularized by Russell and Burch as both a regulatory principle and a governance principle aimed at reducing the total amount of animal distress in science. They thus expect that the 3Rs should, in time, result in changes in total animal experimentation numbers. Communications by Swiss authorities provide stark examples of this expectation. But the 3Rs do not aim at affecting animal experimentation at the level of total numbers; rather, they focus (...) on study design in the individual case. While the underlying philosophy of the 3Rs indeed included a principle of seeking feasible overall reforms, this notion is completely absent in the 3Rs framework itself. Authorities need to stop treating the 3Rs as a means to reduce total distress and should instead invest resources into developing feasible and effective strategies for transformative governance in animal research.

Despite considerable evidence that neural activity in monkeys reflects various aspects of face perception, relatively little is known about monkeys’ face processing abilities. Two characteristics of face processing observed in humans are a subordinate-level entry point, here, the default recognition of faces at the subordinate, rather than basic, level of categorization, and holistic effects, i.e. perception of facial displays as an integrated whole. The present study used an adaptation paradigm to test whether untrained rhesus macaques (Macaca mulatta) display these hallmarks (...) of face processing. In experiments 1 and 2, macaques showed greater rebound from adaptation to conspecific faces than to other animals at the individual or subordinate level. In experiment 3, exchanging only the bottom half of a monkey face produced greater rebound in aligned than in misaligned composites, indicating that for normal, aligned faces, the new bottom half may have influenced the perception of the whole face. Scan path analysis supported this assertion: during rebound, fixation to the unchanged eye region was renewed, but only for aligned stimuli. These experiments show that macaques naturally display the distinguishing characteristics of face processing seen in humans and provide the first clear demonstration that holistic information guides scan paths for conspecific faces.

High Mn2+ concentrations produce cytotoxic effects that can perturb the circuits under study. In the other hand, the MR signal is..

This article attempts to clarify the commitments of a predictive coding approach to perception. After summarizing predictive coding theory, the article addresses two questions. Is a predictive coding perceptual system also a Bayesian system? Is it a Kantian system? The article shows that the answer to these questions is negative.

the question of objectivity in legal interpretation has emerged in recent years as an imprtant topic in contemporary jurisprudence. This book addresses the issue of how and in what sense legal interpretation can be objective. The author supports the possibility of objectivity in law and spells out the content of objectivity involved. He then provides a defence against the classical, as well as less well-known, objections to the possibility of objectivity in legal interpretation. The discussion is thoroughly grounded in metaphysics, (...) which sets the book apart from other similar discussions in jurisprudence. Stavropoulos identifies an important source of resistance to the acceptance of the possibility of objectivity in legal interpretation; a widely held but faulty semantic. He then develops an alternative semantic framework, drawing on influential theories in contemporary philosophy. The book shows that objectivism is a natural, common sensical position, and rejects the currently popular notion that objectivism requires extravagant or bizarre metaphysics. Furthermore, the discussion presents the opportunity to re-interpret major debates in jurisprudence and to show how influential theories, notably H.L.A. Hart's and Ronald Dworkin's, bear on that issue. (shrink)

Zur Soziologie der Wissenschaftssoziologie* Von Nico Stehr Die Wissenschaftssoziologie ist in Bewegung geraten und mit ihr Wissenschaftsgeschichte und Wissenschaftstheorie sowie eine Reihe weiterer, im akademischen Bereich insti­ tutionalisierter wissenschaftlicher Spezialgebiete, die sich "Wissenschaft" reflexiv als Forschungsobjekt gewählt haben!. Die in diesem Band zusammengetragenen Aufsätze sind sowohl Ausdruck als auch Er­ gebnis dieser neuerlichen Entwicklungen auf dem Gebiet der Wissenschaftssoziologie in verschiedenen Ländern und, wie man immer mehr feststellen kann, der ihr einerseits verwandten, andererseits aber auch vorausgehenden und komplementären theoreti­ schen (...) Ansätze in der Wissenschaftsgeschichte und der Wissenschaftstheorie. Der Zu­ sammenhang von Wissenschaftssoziologie (und Wissenssoziologie), Wissensgeschichte und Wissenschaftstheorie als solcher ist zwar keineswegs neu, schon in der Vergangen­ heit haben sich die in diesen Spezialgebieten dominierenden theoretischen Annahmen gegenseitig beeinflußt. Allerdings blieb der angedeutete Zusammenhang, und hier be­ sonders was die Wissenschaftssoziologie angeht, häufig implizit und war zudem von einem, die in der Wissenschaft herrschende Hierarchie von Disziplinen und Spezial­ gebieten wiederspiegelnden Abhängigkeitsverhältnis gekennzeichnet, bei dem die in einem Spezialgebiet vorherrschenden Annahmen die des anderen weitgehend bestimm­ ten. Im Gegensatz dazu kann man immer häufiger beobachten, daß Abhängigkeits­ verhältnisse von Strukturen abgelöst werden, die auf eine wachsende Zusammenarbeit der sich mit (wenn auch verschiedenen) Aspekten der Wissenschaftsentwicklung be­ schäftigenden Spezialgebiete schließen läßt.

As its title suggests, this anthology is a collection of papers presented at a conference on feelings and emotions held in Amsterdam in 2001. One of the symposium’s main goals was to draw some of the most prominent researchers in emotion research together and provide a multi-disciplinary ‘snap shot’ of the state of the art at the turn of the century. In that respect it is truly a cognitive science success story. There are articles from a wide range of fields, (...) encompassing, e.g., philosophy, neuroscience, anthropology, sociology, and psychology. Another.. (shrink)

The proposed dynamic systems model of emotion generation indeed appears considerably more plausible and descriptively adequate than traditional linear models. It also comes much closer to the complex interactions observed in neurobiological research. The proposals regarding self-organization in emerging appraisal-emotion interactions are thought-provoking and attractive. Yet, at this point they are more in the nature of promises than findings, and are clearly in need of corroborating psychological evidence or demonstrated theoretical desirability.

This article applies the concept of prudence to develop the characteristics of responsible risk-modeling practices in the insurance industry. A critical evaluation of the risk-modeling process suggests that ethical judgments are emergent rather than static, vague rather than clear, particular rather than universal, and still defensible according to the discipline’s established theory, which will support a range of judgments. Thus, positive moral guides for responsible behavior are of limited practical value. Instead, by being prudent, modelers can improve their ability to (...) deal with the ethical and technical complexity of the risk-modeling process. While the application of prudence to resolve ethical challenges in risk modeling, an issue of practical importance to managers, is a first in the literature, the practice of applying an ethical lens to issues of pragmatic importance for managers is well established in Maak and Pless (J Bus Ethics 66:99–115, 2006a ; Responsible leadership, 2006b ) among others.

Der wechselseitige Einfluss von Wissen und Freiheit (und damit Demokratie) in modernen, hochkomplexen Gesellschaften wie auch der Wandel ihrer Beziehungen im Laufe der Moderne ist eines der faszinierendsten Themen unseres Zeitalters. Es handelt sich dabei wohl kaum um eine einmal festgeschriebene, statische Beziehung, sondern um eine historisch-dynamische Relation, die immer von der Entwicklung der Wissensformen und der jeweils relevanten Definition von Freiheit mitbestimmt wurde und wird. Dieses Buch beleuchtet die neuartigen Probleme und Herausforderungen der Demokratie im Angesicht der rapide anwachsenden (...) wissenschaftlichen Erkenntnisse in gegenwärtigen Gesellschaften und gibt einen Überblick über soziologische Perspektiven von Weber, Dewey und Foucault bis in die Gegenwart.

Emotion experience reflects some of the outcomes of the mostly nonconscious processes that compose emotions. In my view, the major processes are appraisal, affect, action readiness, and autonomic arousal. The phenomenology of emotion experience varies according to mode of consciousness (nonreflective or reflective consciousness), and to direction and mode of attention. As a result, emotion experience may be either ineffable or articulate with respect to any or all of the underlying processes. In addition, emotion experience reflects the degree to which (...) the emotion processes control perception, thought, action and bodily arousal. (shrink)

The concept of “appraisal” has been used in the literature in a dual way: to refer to the content of emotional experience, as well as to the cognitive antecedents of emotions. I argue that appraisal in the former sense is what is contained in information in self-reports and that this information is of limited use for making inferences on emotion antecedents. This is so because emotional experience may contain appraisals that are part of the emotional response rather than belonging to (...) its causes. They often result from elaboration of the experience after it has begun to be generated. Although in most or all emotions some cognitive appraisal processes are essential antecedents, these processes may be much simpler than self-reports (and the semantics of emotion words) may suggest. The appraisal processes that account for emotion elicitation can be assumed to be of a quite elementary kind. (shrink)

In-vivo phenotyping of genetically engineered mouse models for amyotrophic lateral sclerosis is established by combining BT-MRI and CASL G. Vanhoutte1, E. Storkebaum2, P. Carmeliet2, A. Van der Linden1.

We report and compare the performance of different learning algorithms based on data from cortical recordings. The task is to predict the orientation of visual stimuli from the activity of a population of simultaneously recorded neurons. We compare several ways of improving the coding of the input (i.e., the spike data) as well as of the output (i.e., the orientation), and report the results obtained using different kernel algorithms.

In this issue we include contributions from the individuals presiding at the panel All in a Jurnal's Work: A BABEL Wayzgoose, convened at the second Biennial Meeting of the BABEL Working Group. Sadly, the contributions of Daniel Remein, chief rogue at the Organism for Poetic Research as well as editor at Whiskey & Fox , were not able to appear in this version of the proceedings. From the program : 2ND BIENNUAL MEETING OF THE BABEL WORKING GROUP CONFERENCE “CRUISING IN (...) THE RUINS: THE QUESTION OF DISCIPLINARITY IN THE POST/MEDIEVAL UNIVERSITY” SEPTEMBER 21ST, 2012: SESSION 13 MCLEOD C.322, CURRY STUDENT CENTER NORTHEASTERN UNIVERSITY, BOSTON, MA. Traditionally, a wayzgoose was a celebration at the end of a printer’s year, a night off in the late fall before the work began of printing by candlelight. According to the OED, the Master Printer would make for the journeymen “a good Feast, and not only entertains them at his own House, but besides, gives them Money to spend at the Ale-house or Tavern at Night.” Following in this line, continent. proposes in its publication(s) a night out and a good Feast, away from the noxious fumes of the Academy and into a night of revelry which begins, but does not end, at the alehouse or Tavern. continent. proposes that the thinking of the Academy be freed to be thought elsewhere, in the alleys and doorways of the village and cities, encountered not in the strictly defined spaces of the classroom and blackboard (now white) but anticipated and found where thinking occurs. Historically, academic journals have served a different purpose than the Academy itself. Journals (from the Anglo-Fr. jurnal , "a day," from O.Fr. jornel , "day, time; day's work," hence the journalist as writer of the news of the day ) have served as privileged sites for the articulation and concretization of specific modes of knowledge and control (insemination of those ideas has been formalized in the classroom, in seminar). In contrast, the academic journal is post-partum and has been an old-boys club, an insider trading network in which truths are (re)circulated against themselves, forming a Maginot Line against whatever is new, or the distinctly challenging. All in a Jurnal’s Work will discuss (in part) the ramifications of cheap start-up publications that are challenging the traditional ensconced-in-ivory academic journals and their supporting infrastructures. The panel will be seeking a questioning (as a challenging) towards the discipline of knowledge production/fabrication (of truth[s]) and the event of the Academy (and its publications) as it has evolved and continues to (d)evolve. Issues to be discussed will revolve around the power of academic publishing and its origins, hierarchical versus horizontal academic modules (is there a place for the General Assembly in academia?) and the evolving idea of the Multiversity as a site(s) of a (BABELing) multivocality in the wake of the University of Disaster. A CONTINUOUS ACT Nico Jenkins In Pierre Hadot’s extraordinary book, Philosophy as a Way of Life , the practices of philosophy—that is the exercise of what we can term pre-institionalized love of wisdom, what Philo of Alexandria described as a training towards wisdom—are described as, following the Stoics, “a continuous act, permanent and identical with life itself, which had to be renewed at each instant.” This renewal of thinking, this coming to be of being itself —meeting itself on its own ground, concerns the way philosophy is practiced, and more often, taught, or rather not taught. Hadot continues his thinking with a description of what happens to the structure of thought in the medieval ages as it becomes adopted—co-opted— by the university, and by extension, by the institution of the church. Philosophy becomes no longer a way of living, no longer a praxis as such but becomes a condition that is locked in a theoretical construct, one which was literally removed from life (and in life we read then love, wisdom, being etc, also the home, the market, the field, the street) and secured behind the high walls of the monastery (which were shortly replaced by the high walls of the Academy) where thinking unfortunately rests for the most part today. Hadot writes further that this dangerous movement of removal reduces thinking to a theoretical practice akin to the mythical Ouroborous; “education was thus no longer directed toward people who were to be educated with a view to becoming fully developed human beings, but to specialists, in order that they might learn how to train other specialists.” Thought then is trapped behind the walls of the academy, and with the exception of such thinkers as Spinoza, Descartes, and Liebnitz as well as others who think from an outside in, thought remains, in the form of Kant, Fichte, Hegel, a practice reduced or removed from life and restricted to what Schopenhauer will call “mere fencing in front of the mirror.” This is of course the tendency today and philosophy remains, for the most part, a discourse produced and thought inside the academy and disseminated, in seminated through university presses and of course the academic journal. It seems necessary to me that we have to have a place, a return, to a thinking which is closer to the Stoics, closer to the pre-Socratics, to a thinking which is a practice of becoming, a training to think, to live, to die. this is not south romantic than imperative . This thinking is one of a deep ir responsibility because it is not known, it is not figured out. It requires a risk and what Heidegger calls a leap (for there is no bridge to it). I call it irresponsible because for too long sanctioned thought has had as its premise the idea that thinking has a goal, a direction, a telos ; that it is not an activity but a process which gives a product; that the responsibility of thinking in turn demand an answer. In my mind, only freed from that goal can thinking, in contrast, bask in its own thinking, bask in a state in which the unknown can remain unknown, that mystery can rest as mystery. This is not to say that the world needs no answers, or to promote a Whitmanesque “leaning and loafing” as the only valid practice. It is only to say that for too long, thinking has been validated by the academy, by the answerable, by the already decided. To me, this requires—as an answer— the ir responsibility of thought, what Nancy calls, “a world for which all is not already done (played out, finished, enshrined in a destiny), nor entirely still to do (in the future for always future tomorrows).” This is a thinking not sanctified by the academy, made sacred by the church or the palace but rather it takes place on the périphérie , beyond the ring road, in alleyways behind the marketplace, in cafes stained with the syphilitic patina of irresponsible talk, of loose talk, the kind of talk made loose not only by the tankard and the goblet by the practice and training of attuned thinking. continent. was formed as a collective of thinkers coming out of the European Graduate School (also known as the University of Disaster) three years ago, in an effort to combat, or challenge, the dominant paradigm which isolates thinking from the street, from life, from where perhaps wisdom tends to emerge. We feel that not only is the university herself no longer the privileged site of where true thinking takes place—and where only official thought can take place—but that the very artificiality of the academy denies thinking—at times—authentic, thought. Our goal at continent. is to create a media agnostic publication which is rigorous in its intellectual underpinnings but which will remain permanently beyond and out of reach of the academy. Though many of us butter our bread with academic paychecks (maid!) we attempt to keep continent. as a refuge—and a refugee—from the University in ruins, from the University as a site of preformed and institutionalized pre-set dialogues. In concert with other publications-both cyber and print—as well as various blogs we are attempting to re-dialogize the dialogue of thinking. We are attempting both to speak to— as well as with and against —the university as a site of accreted knowledge. We have not been utterly successful and continue to attempt to define what that role of being perpetually beyond is (while still trying to maintain rigorous intellectual standards) but it is just that, a goal, which is perpetually opening, perpetually unanswered, perhaps even by design, perpetually unanswerable.

Film theory and its emphasis on political and ideological readings of films dominated much of cinema studies in the '70s and '80s. Since then, in response to what some view as the shortcomings of theoretical approaches, a variety of other methods have emerged or reemerged. In many ways, as Nico Baumbach argues, "Anti-Grand Theory" has won the day but its victory is, in part, based on misreadings or simplifications of '70s film theory. In particular, Baumbach views contemporary critical approaches to (...) film as abandoning the crucial and productive ways in which theory understands the relationship between cinema, politics, and art. Baumbach does not advocate a return to the orthodoxies of the seventies but rather reads the work of Ranciere, Badiou, and Agamben as providing new ways of thinking about the history of film theory and how film creates its own way of thinking about politics. Moreover, at a time when digital technologies are asking us to think of film and the film image in new ways, the work of these thinkers once again asks, "What is Cinema?" but in a more expansive sense that can help us account for transformations in how moving images are produced, distributed, and exhibited in the twenty-first century.
