In 1976 an interdisciplinary study on risks and risk evaluations was inaugurated in Sweden and was sponsored by the Committee for Future-oriented Research. One of the basic assumptions of the Swedish risk project was that modern society has created “new, increasingly complicated and large-scale technical systems.” It also assumed that “large systems are economically efficient, but vulnerable and therefore create risks.” A third assumption was that “the ever rising standard of living is purchased at the cost of certain additional risks.” (...) The perspective of the project was thus markedly historically oriented. (shrink)

In this discussion, Steve Fuller’s book Dissent over Descent is criticized mainly because he draws conclusions from wishful thinking and uses ancient and medieval scientists as well as theologians in his efforts to invalidate the theory of evolution. He is also criticized for drawing universal conclusions from a Eurocentric version of history. If science and technology studies is to regain its reputation, its representatives have to use relevant statements and argue more rationally.

The case for the independence of featural processing supports Merge and FLMP alike. The target article's criticisms of the latter model are founded on misunderstanding its application to natural language processing. In fact, the main difference in the functional properties of the models is the FLMP's ability to account for graded perceptual experience. @T3:It is startling to be informed that beliefs you have held for a quarter of a century are indefensible and implausible. So it comes as a relief to (...) discover that it was all just a big misunderstanding. (shrink)

Les questions de communication sont au coeur des «perceptions du risque» car la grande majorité des risques ne seraient connus que de ceux qui l'expérimentent n'eut été les médias. Le champ historiquement individualiste de la «perception du risque» a manifesté peu d'intérêt pour le contenu des mass media et leur rôle dans la construction d'une pensée sur le risque. Bien au contraire, le processus de «l'information» sur le risque était situé dans la pensée individuelle, la question centrale étant: pourquoi certains (...) risques sont-ils grossis par les individus tandis que d'autres sont minimisés? Les médias jouent un rôle essentiel dans l'amplification de certains risques et les récepteurs de l'information sont considérés comme passifs devant les stimuli médiatiques. Il faut en fait nuancer l'approche pour saisir la dimension profonde de l'appréhension du risque. En passant de la notion de «perception du risque» à celle de «représentation du risque», on peut davantage cerner les liens entre médias et pensée profonde.Issues of communication lie at the heart of "risk perception" since the vast majority of risks would be known to only those who experience them were it not for the mass media. The historically individualist field of "risk perception" has tended to pay little attention to the contents of the mass media and the role these played in constructing risk-related thinking. Rather, the processing of risk "information" was situated within individual’s minds with the central question being: why are some risks overplayed by certain individuals while others more serious risks are underplayed? The media are seen to play a major role in the amplification of certain risks with those who receive such information being viewed as rather passive followers of media signals. The starting point of this paper is the need for a more nuanced approach to the lay dimension of the apprehension of risks. The paper outlines how a shift from "risk perception" to "risk representation" highlights the links between media and lay thinking. (shrink)

On childhood, childhood culture and child perspective in a cross-cultural frame of reference.

Willensfreiheit wird bestritten, weil sich der Begriff nicht logisch konsistent definieren lässt und weil inzwischen auch neurobiologische Anhaltspunkte gegen ihre Existenz sprechen. Anders als in der biblisch-reformatorischen Tradition gehört die Willensfreiheit aber zum Kern des aufgeklärten Menschenbildes. Und auch in der Theologie scheint die Bestreitung der Willensfreiheit unweigerlich auf die Lehre von der doppelten Prädestination hinauszulaufen, so dass seit Pietismus und Aufklärung auch die evangelische Theologie ihrem Ursprung untreu wurde. In dem Buch werden die Perspektiven der Philosophie, Neurobiologie und Theologie (...) zum Thema Willensfreiheit zusammengeführt. Die Argumente und Befunde gegen Willensfreiheit sind weit stärker als die zu ihren Gunsten. Deswegen existieren bislang nur Positionen, die den Determinismus akzeptieren, oder solche, die aus der Negation des Determinismus doch noch eine Möglichkeit für Willensfreiheit im menschlichen Gehirn zu finden hoffen. Die Studie geht einen völlig neuen Weg, indem sie den Determinismus der Aussenwelt bestreitet, und dies im Anschluss an die erkenntnistheoretischen Debatten über das Wesen des Quantenindeterminismus. Dabei wird aber gerade kein freier Wille postuliert, sondern ein Konzept aktiver Lebensführung entwickelt, in dem Bildung zur Verwirklichung von vorgenommenen Zielen eine besondere Rolle spielt."-- Back cover.

"This book is addressed to the one who lives in a passionate quest for deepened awareness, who hungers to touch and taste human existence more intimately, who delights in the celebration of now." "In the era of the multiversity with its fragments of introverted expertise, it does sound absurdly ambitious to make an integrative attempt at synoptic reflection, seeking to conjoin disparate insights from developmental psychology, psychotherapy, ontology, epistemology, ethics, phenomenology, the fine arts, jurisprudence, linguistics, theology, hermeneutics, liturgics, history, and (...) the philosophy of history...Admittedly it is not because I am an expert in any or all of these fields, but instead a human being--a single, experiencing, time-bound, warm-bodied human being--that emboldens me to speak with any assurance about the human situation. More than most other academic bailiwicks, my own academic discipline (theological ethics) invites and demands such integrative reflection on man, culture, time, being and value, dysfunctional and constructive human behavior." "Our thesis: The structure of human awareness emerges directly out of man's temporal situation and his relation to being." (excerpts from the Introduction, by Thomas C. Oden). (shrink)

Organizational changes are common in elder care today. Such changes affect caregivers, who are essential to providing good quality care. The aim of the present study was to illuminate caregivers’ experiences of working in elder care while under threat of organizational change and termination notice. Qualitative content analysis was used to examine interview data from 11 caregivers. Interviews were conducted at three occasions during a two‐year period. The findings show a transition in their experiences from ‘having a professional identity and (...) self‐confidence’, to ‘being a professional in a threatening situation caused by someone else’ and to ‘struggling to adapt to a changed working environment as a person and a professional’. The caregivers experienced a loss of pride and satisfaction. Previous literature indicates that this may have consequences for the quality of care and that employees may be at risk of negative health effects. However, the caregivers continued to struggle, doing their best to complete their duties. The study has implications for high‐level decision‐makers, managers and caregivers in similar work–life situations in that it deals with factors that facilitate or impede similar transitions.

Shepard's concept of internalization does not suggest mechanisms which help to understand how the brain adapts to changes, how representations of a steadily changing environment are updated or, in short, how brain learning continues throughout life. Neural mechanisms, as suggested by Barlow, may prove a more powerful alternative. Brain theories such as Adaptive Resonance Theory (ART) propose mechanisms to explain how representational activities may be linked in space and time. Some predictions of ART are confirmed by psychophysical and neurophysiological data. (...) [Barlow; Shepard]. (shrink)

We question the ecological plausibility as a general model of cognition of van der Velde's & de Kamps's combinatorial blackboard architecture, where knowledge-binding in space and time relies on the structural rules of language. Evidence against their view of the brain and an ecologically plausible, alternative model of cognition are brought forward.

Studies of the conceptual abilities of nonhuman primates demonstrate the substantial range of these abilities as well as their limitations. Such abilities range from categorization on the basis of shared physical attributes, associative relations and functions to abstract concepts as reflected in analogical reasoning about relations between relations. The pattern of results from these studies point to a fundamental distinction between monkeys and apes in both their implicit and explicit conceptual capacities. Monkeys, but not apes, might be best regarded as (...) “paleo‐logicans” in the sense that they form common class concepts of identity on the basis of identical predicates (i.e., shared features). The discrimination of presumably more abstract relations commonly involves relatively simple procedural strategies mediated by associative processes likely shared by all mammals. There is no evidence that monkeys can perceive, let alone judge, relations‐between‐relations. This analogical conceptual capacity is found only in chimpanzees and humans. Interestingly, the “analogical ape,” like the child, can make its analogical knowledge explicit only if it is first provided with a symbol system by which propositional representations can be encoded and manipulated.

Lehar's Gestalt Bubble model introduces a computational approach to holistic aspects of three-dimensional scene perception. The model as such has merit because it manages to translate certain Gestalt principles of perceptual organization into formal codes or algorithms. The mistake made in this target article is to present the model within the theoretical framework of the question of consciousness. As a scientific approach to the problem of consciousness, the Gestalt Bubble fails for several reasons. This commentary addresses three of these: (1) (...) the terminology surrounding the concept of consciousness is not rigorously defined; (2) it is not made evident that three-dimensional scene perception requires consciousness at all; and (3) it is not clearly explained by which mechanism(s) the “picture-in-the-head,” supposedly represented in the brain, would be made available to different levels of awareness or consciousness.

The heuristic value of Pylyshyn's cognitive impenetrability theory is questioned in this commentary, mainly because, as it stands, the key argument cannot be challenged empirically. Pylyshyn requires unambiguous evidence for an effect of cognitive states on early perceptual mechanisms, which is impossible to provide because we can only infer what might happen at these earlier levels of processing on the basis of evidence collected at the post-perceptual stage. Furthermore, the theory that early visual processes cannot be modified by cognitive states (...) implies that it is totally pointless to try to investigate interactions between consciousness and neurosensory processes.

This article presents psychophysical evidence that the Kanizsa Square does not produce an 'object superiority effect' previously reported in similar Gestalt configurations. Implications of the findings for Gestalt theory are addressed.

Le mouvement skinhead se compose de deux entités : les skinheads racistes-nationalistes et les skinheads antiracistes. S’inspirant des théories psychosociologiques relatives aux représentations sociales et aux minorités actives proposées par Serge Moscovici , il décrit les styles de comportement précis de chaque groupe skin, leurs divergences et leurs ressemblances, et analyse la façon dont la société, aidée par les media, ne retient qu’une seule représentation sociale, celle des skinheads nationalistes. Malgré l’univocité de la représentation, ce qui ressort de 19 entretiens (...) avec les skinheads, c’est l’idée de pluralité identitaire combinée à un ancrage urbain très important.The skinhead movement is divided into two groups : the racist-nationalist skinheads and the antiracist skinheads. Taking into account the social-psychological theories of social representations and active minorities, proposed by Serge Moscovici , it describes the styles of behavior of each skin group, their divergences and resemblances and analyses how society, with the help of the media, has built only one social representation of the nationalist skinheads. In spite of this univocal representation, what is underlined through the nineteen interviews with skinheads is a form of plural identity linked to a strong urban anchoring. (shrink)

A simple working taxonomy with three classes of pictorial completion is proposed as an alternative to Pessoa et al.'s classification: area, surface, and contour completion. The classification is based on psychophysical evidence, not on the different phenomenal attributes of the stimuli, showing that pictorial completion is likely to involve mechanistic interactions in the visual system at different levels of processing. Whether the concept of “filling-in” is an appropriate metaphor for the visual mechanisms that may underlie perceptual completion is questioned.
