Cowan assumes a unitary capacity-limited attentional focus. We argue that two main problems need to be solved before this assumption can complement theoretical knowledge about human cognition. First, it needs to be clarified what exactly the nature of the elements (chunks) within the attentional focus is. Second, an elaborated process model needs to be developed and testable assumptions about the proposed capacity limitation need to be formulated.

Maintaining and coordinating multiple task-sets is difficult and leads to costs, however task-switching training can reduce these deficits. A recent study in young adults demonstrated that this training effect occurs at an amodal processing level. Old age is associated with reduced cognitive plasticity and further increases the performance costs when mixing multiple tasks. Thus, cognitive aging might be a limiting factor for inducing cross-modal training effects in a task-switching environment. We trained participants, aged 62–83 years, with an auditory task-switching paradigm (...) over four sessions, to investigate whether training-related reductions in task-switching costs would also manifest in an untrained visual modality version of the task. Two control groups trained with single tasks or not trained allowed us to identify improvements specific to task-switching training. To make statistical evaluations of any age differences in training and cross-modal transfer, the data from the Kattner cohort were incorporated into the present analysis. Despite the tendency for older adults to respond more cautiously, task-switching training specifically led to a mixing cost reduction in both trained and untrained modalities, the magnitude of which was statistically similar regardless of age. In line with a growing body of research, we failed to observe any far transfer effects in measures of inhibition, working memory or fluid intelligence. Overall, we conclude that any apparent cognitive limitations associated with aging do not prevent cognitive control processes which support set-shifting from improving at an amodal level. (shrink)

To evoke the impression of movement in the “immobile” image is one of the central motivations of the visual art, and the activating effect of images has been discussed in art psychology already some hundred years ago. However, this topic has up to now been largely neglected by the researchers in cognitive psychology and neuroscience. This study investigates – from an interdisciplinary perspective – the formation of lateralised instances of motion when an observer perceives movement in an image. A first (...) step was to identify images that evoke a perception of movement in a certain direction and to give this a rating. Reaction times leading to the engagement of a joystick following the presentation of images are used to evidence the postulated movement occasioned by the perception of movement in an image. Where the required direction of joystick moves matched the expected perception of movement direction in the image, considerably shorter reaction times were recorded. The experiment was able to prove a “movement-image compatibility effect” in observers of images. Based on this, the paper revisits and brings up to date the theses on motor sensory response to images which were developed in art psychology at the beginning of the 20th century. It furthermore contributes an embodiment theory interpretation to the prevalent representational explanation of compatibility effects. (shrink)

Dieser Band, aus Jenenser Lehrveranstaltungen erwachsen, richtet sich vornehmlich an Studenten, denen an Hand der überlieferten Fragmente des Horos des Konzils von 754 ein Einstieg in die Gedankenwelt und die Argumentation der bilderablehnenden Theologen in der ersten Phase des Ikonoklasmus ermöglicht werden soll. Richtig ist, daß dem Horos dabei eine besondere Rolle zukommt, da er weitgehend rekonstruierbar ist. Aus welchem Grunde aber die Peuseis Konstantins V., die andere wichtige Quelle für die Eruierung der ikonoklöastischen Beweisführung in der ersten Periode des (...) Streits, von der Behandlung ausgeschlossen bleiben, wird nicht erklärt. Auch fehlt eine stichhaltige Begründung für die im Vorwort genannte Einschränkung: „Eine Erfassung und Auswertung der gesamten zugehörigen Sekundärliteratur konnten und wollten wir nicht leisten“ (S.

Power is often taken to be a central concept in social and political thought that can contribute to the explanation of many different social phenomena. This article argues that in order to play this role, a general theory of power is required to identify a stable causal capacity, one that does not depend on idiosyncratic social conditions and can thus exert its characteristic influence in a wide range of cases. It considers three promising strategies for such a theory, which ground (...) power in (1) the ability to use force, (2) access to resources, or (3) collective acceptance. It shows that these strategies fail to identify a stable causal capacity. The lack of an adequate general theory of power suggests that the concept lacks the necessary unity to play the broad explanatory role it is often accorded. (shrink)

Diese Arbeit erlautert und interpretiert Platons Dialog Phaidon. Vor dem Hintergrund der Ausfuhrungen zu Eidos, Psyche und Unsterblichkeit und deren Relationen zueinander stellt diese Untersuchung einen prazisen Kommentar dar, der eine synchrone Lekture des Phaidon stutzt. Die Interpretationen der Dialogaussagen zu den Eide, zur Seelenkonzeption und zur Unsterblichkeitslehre werden erganzt durch den Vergleich mit den grundlegenden philosophischen Todes- und Jenseitsauffassungen der Vorsokratik. Neben der eng am Text entwickelten Uberprufung aller Unsterblichkeitsbeweise, der Einwande des Simmias und des Kebes und der Widerlegungen (...) dieser Einwande durch Sokrates, beschaftigt sich diese Arbeit ferner mit einer detaillierten Explikation des Hypothesisverfahrens.".

Foucault's theory of power and subjectification challenges common concepts of freedom in social philosophy and expands them through the concept of 'freedom as critique': Freedom can be defined as the capability to critically reflect one's own subjectification, and the conditions of possibility for this critical capacity lie in political and social institutions. The article develops this concept through a critical discussion of the standard response by Foucault interpreters to the standard objection that Foucault's thinking obscures freedom. The standard response interprets (...) Fou-cault's later works, especially The Subject and Power, as a solution to the problem of freedom. It is mistaken, because it conflates different concepts of freedom that are present in Foucault's work. By differentiating these concepts, this paper proposes a new institutionalist approach to solve the problem of freedom that breaks with the partly anarchist underpinnings of Foucault scholarship: As freedom as critique is not given, but itself a result of subjectification, it entails a demand for 'modal robustness' and must therefore be institutionalized. This approach helps to draw out the consequences of Foucault's thinking on freedom for postfoundationalist democratic theory and the general social-philosophical discussion on freedom. (shrink)

This paper aims to give an insight into developments that contributed to the significance of the work of Jakob von Uexküll and stresses the importance of his occupation in Hamburg. A biographical survey pays tribute to the implication of the historical pretext and context. A scientific survey describes findings and ideas of Uexküll that proved important for the development of biology and the cognitive sciences. In addition, this paper sets out to reject the common notion that Uexküll’s concepts were ideas (...) of a purely theoretical and philosophical character. It confirms that in fact the central aims of his work were to sustain the empirical method in biology and to give biology a sound epistemological basis. Some examples show how historical and theoretical developments converged at Uexküll’s Institut für Umweltforschung in Hamburg and ignited a productive research activity. (shrink)

Wie können Freiheit und Widerstand innerhalb von Foucaults Theorie der Macht und Subjektivierung konzipiert werden? Karsten Schubert liefert die erste systematische Rekonstruktion der sozialphilosophischen Debatte um Freiheit bei Foucault und eine neue Lösung für das Freiheitsproblem: Freiheit als die Fähigkeit zur reflexiven Kritik der eigenen Subjektivierung - kurz: Freiheit als Kritik - ist das Resultat von freiheitlicher Subjektivierung in politischen Institutionen. Der Band zeigt so die Konsequenzen von Foucaults Freiheitsdenken für die Demokratietheorie und die allgemeine sozialphilosophische Freiheitsdiskussion auf.

Scientific procedures are widely expected to be unbiased, in the sense that they do not single out one specific set of claims about which they yield false results more often than about others. This assumed feature of the practices of science can be called procedural objectivity. I argue that attempts to analyze procedural objectivity on the level of individual rationality fail. The appropriate balance of inductive risks for each scientific investigation hinges upon value judgments for which no binding, ‚neutral‘ standard (...) can be derived from universal principles. I make the case that the perspective of social epistemology offers a much more promising approach to establish a substantial conception of procedural objectivity. I examine two genuinely social elements of the sciences’ procedural objectivity. One consists in conventional standards, which are adopted by research communities in order to facilitate epistemic trust and which impose constraints on methodological choices that affect the balance of inductive risks. The other is constituted by the plurality of approaches within research communities and the mechanism of mutual criticism. Procedural objectivity in science thus becomes understandable as a social phenomenon. (shrink)

In recent years, a variety of philosophers have argued that the fundamental bearers of representational properties like truth are concrete particulars produced by cognitive agents—representational vehicles (“RVs”), as I will call them. This view apparently conflicts with other judgments that are part of our common sense understanding of truth. For instance, it is plausible that there are truths about the Milky Way that have and never will never be articulated by anyone. Whatever these truths are, it looks like they cannot (...) be RVs, because an RV is articulated just in case it exists. In this paper, I argue that it is consistent to hold that the fundamental truth-bearers are representational vehicles, while also acknowledging the existence of unarticulated truths. I argue that truth is a property that derivatively holds of kinds of RVs, that these provide the basis for our judgments that there are unarticulated truths, and I defend the view against putative counter-examples.

English summary: The Self and the Other: both face each other, and from our own Here, we look at the unknown There. The Self is only limited by what is unknown, and vice versa. What makes the Self? In search of identity, positions from antiquity to postmodernism are considered. From the geographical point of view, the author presents the question of the Where of the Self: how important is space for the construction of one's own identity? Here, the investigation must (...) tread a side road, which passes different geographical spatial concepts. For space for the construction of the identity of the Self must first be found.

This chapter provides an analysis of the long process of introducing an electronic identity for online authentication in Germany. This process is described as a multi-facet innovation, involving actors from different policy fields shifting over time. The eID process started in the late ‘90s in the context of eGovernment and eCommerce with the legislation on e-signatures, which were supposed to allow for online authentication of citizens. When after 5 years it was recognized that this was not the case, a new (...) digital ID card, which had meanwhile been announced, was chosen as token for the eID. This process was dominated by the concerns for visual inspection and border control, including the storage of digital fingerprints. Under the leadership of the Ministry of the Interior (BMI) and technical guidance of the Federal Agency for Information Security (BSI), technical specifications have to a large extent been adopted from the electronic passport, which had been smoothly introduced 2 years before. However, in the legislative process some concern regarding digital fingerprints on the eID card was raised and led to an opt-in solution. In 2009, a bill on the new ID card was passed which regulates the eID function for online authentication as well. This is characterized as a radical innovation by introducing a double-sided, mutual authentication of the citizen and the service provider and implementing the principle of proportionality regarding the access of service providers to data on the chip. At the time of writing, field tests are conducted. Roll-out of the new eID card is to start in November 2010. Therefore no figures about adoption can be provided here. (shrink)

Goldstein and Gigerenzer (2002) [Models of ecological rationality: The recognition heuristic. Psychological Review, 109 (1), 75–90] found evidence for the use of the recognition heuristic. For example, if an individual recognizes only one of two cities, they tend to infer that the recognized city has a larger population. A prediction that follows is that of the less‐is‐more effect: Recognizing fewer cities leads, under certain conditions, to more accurate inferences than recognizing more cities. We extend the recognition heuristic to group decision‐making (...) by developing majority and lexicographic models of how recognition information is used by groups. We formally show when the less‐is‐more effect is predicted in groups and we present a study where three‐member groups performed the population comparison task. Several aspects of our data indicate that members who can use the recognition heuristic are, not in all but in most cases, more influential in the group decision process than members who cannot use the heuristic. We also observed the less‐is‐more effect and found that models assuming that members who can use the recognition heuristic are more influential better predict when the effect occurs. (shrink)

Als kulturgeschichtlich bedeutsame Phänomene entstammen Masken der Ritual- und Theaterpraxis und traten schon in der Antike als Metapher in den Sprachgebrauch über. Kaum ein Philosoph hat den Masken so viel Raum gegeben wie Friedrich Nietzsche: Sie sind ihm Hilfsmittel der Erkenntnis und conditio humana, sie ermöglichen Höflichkeit und Selbstschutz, fungieren aber auch als Darstellungsform. Corinna Schubert führt zentrale Themen seines Denkens unter einem neuen Gesichtspunkt zusammen und erschließt sie als Philosophie der Masken. Dabei geht es nicht nur darum, was (...) Nietzsche über Masken denkt, sondern auch, wie er mit und in Masken denkt. (shrink)

Social order and social change is based on social action. All sociological theories of action agree on this assumption. Beyond that insight action theories disagree on basic notions of how action can be explained, on basic principles clarifying the selection of action and on basic motivations of action as starting point to construct theories of social order and social change. Contemporary sociology accepts the multidimensionality of theoretical approaches. Open are questions of how action theories can be differentiated, related or combined (...) to offer analytical instruments for empirical research. The idea this essay brings forward is that the classical dualism between utilitarism (homo oeconomicus) and normativism (homo sociologicus) is transcended in support of action theories concentrating on the meaning of culture (cultural turn), communication (linguistic turn), and on creativity (dialogical turn). Integrated as a new typology these five action theories provide an analytical framework to research social order and social conflicts of modern societies. (shrink)

Diese Studie bietet eine pragmatistische Deutung von Erkenntnis. Durch eine detaillierte Analyse im Kontext von Sprachphilosophie und Philosophie des Geistes legt der Autor dar, warum Wissen seinen Ursprung im Konnen hat. Denn bei genauer Betrachtung beschreiben die Bedingungen fur Wissen letztlich eine praktische Kompetenz. Durch die Verknupfung einer normativen Pragmatik mit einer inferentiellen Semantik macht der Autor deutlich, warum es einer solchen Kompetenz bedarf, um Uberzeugungen uberhaupt erst haben und rechtfertigen zu konnen. Im Rahmen eines Deflationismus zeigt er dagegen, dass (...) Wahrheit keine notwendige Bedingung fur Wissen, sondern vielmehr ein Mittel der Zustimmung und der Verallgemeinerung ist.". (shrink)

Platon ist nach Homer der antike Autor mit der reichhaltigsten Rezeption vom Altertum über das Mittelalter bis in die Neuzeit. Gleichwohl und gerade aus diesem Grund ist diese bisher allenfalls bruchstückhaft aufgearbeitet worden. Die Autoren versuchen, diesem alten Ziel geisteswissenschaftlicher Forschung auf neuen Wegen näherzukommen, indem sie eine informationswissenschaftliche Perspektive auf Platon und seine Rezeption anwenden. Dazu sind innovative Methoden der Paraphrasensuche entwickelt worden, um diese auch als Methode altertumswissenschaftlich und kulturwissenschaftlich interessierter Forschung zu etablieren.

Epistemic trust is crucial for science. This article aims to identify the kinds of assumptions that are involved in epistemic trust as it is required for the successful operation of science as a collective epistemic enterprise. The relevant kind of reliance should involve working from the assumption that the epistemic endeavors of others are appropriately geared towards the truth, but the exact content of this assumption is more difficult to analyze than it might appear. The root of the problem is (...) that methodological decisions in science typically involve a complex trade-off between the reliability of positive results, the reliability of negative results, and the investigation's power. Which balance between these is the ‘correct’ one can only be determined in light of an evaluation of the consequences of all the different possible outcomes of the inquiry. What it means for the investigation to be ‘appropriately geared towards the truth’ thus depends on certain value judgments. I conclude that in the optimal case, trusting someone in her capacity as an information provider also involves a reliance on her having the right attitude towards the possible consequences of her epistemic work. 1 Introduction2 Epistemic Reliance within the Sciences3 Methodological Conventionalism4 Trust in Science5 Conclusions.

When interests and preferences of researchers or their sponsors cause bias in experimental design, data interpretation or dissemination of research results, we normally think of it as an epistemic shortcoming. But as a result of the debate on science and values, the idea that all extra-scientific influences on research could be singled out and separated from pure science is now widely believed to be an illusion. I argue that nonetheless, there are cases in which research is rightfully regarded as epistemologically (...) deficient due to the influence of preferences on its outcomes. I present examples from biomedical research and offer an analysis in terms of social epistemology. (shrink)

The issue of political violence is mostly absent from current debates about power. Many conceptions of power treat violence as wholly distinct from or even antithetical to power, or see it as a mere instrument whose effects are obvious and not in need of political analysis. In this paper, I explore what kind of ontology of power is necessary to properly take account of the various roles that violence can play in creating and maintaining power structures. I pursue this question (...) by contrasting the views of Hannah Arendt and Michel Foucault. For Arendt, power is generated and maintained by communicative practices. She argues that power and violence are ‘opposites’ because violence can only destroy but not create these practices. In contrast, Foucault’s conception explicitly allows violence to play a constitutive role in generating power. I argue that while Arendt is right to insist that power and violence are not identical, it does not follow that violence cannot play any role in constituting power. Guided by Foucault’s approach, I formulate a non-dualist account of the relationship between power and violence that takes seriously the role that bodies, material things, and built infrastructures play in making social relations ‘more durable’ and constituting power.

The notion of ecological rationality implies that the accuracy of a decision strategy depends on features of the information environment in which it is tested. We demonstrate that the performance of a group may be strongly affected by the decision strategies used by its individual members and specify how this effect is moderated by environmental features. Specifically, in a set of simulation studies, we systematically compared four decision strategies used by the individual group members: two linear, compensatory decision strategies and (...) two simple, noncompensatory heuristics. Individual decisions were aggregated by using a majority rule. To assess the ecological rationality of the strategies, we varied (a) the distribution of cue validities, (b) the quantity, and (c) the quality of shared information. Group performance strongly depended on the distribution of cue validities. When validities were linearly distributed, groups using a compensatory strategy achieved the highest accuracy. Conversely, when cue validities followed a J-shaped distribution, groups using a simple lexicographic heuristic performed best. While these effects were robust across different quantities of shared information, the quality of shared information exerted stronger effects on group performance. Consequences for prescriptive theories on group decision making are discussed. (shrink)

As nation-states make greater efforts to regulate the flow of people on the move—refugees, economic migrants, and international travelers alike—advocates of DNA profiling technologies claim DNA testing provides a reliable and objective way of revealing a person’s true identity for immigration procedures. This article examines the use of DNA testing for family reunification in immigration cases in Finland, Germany, and the United States—the first transatlantic analysis of such cases—to explore the relationship between technology, the meaning of family, and immigration. Drawing (...) on our analyses of archival records, government documents, and interviews with immigration stakeholders, we argue that DNA testing is not conclusive about the meaning of family. While the technology may facilitate decision making for both would-be immigrants and state officials, our study shows hesitancy among the latter to let DNA testing make the final determination. We introduce the concept of social validity—whether the interpretation of test results matches social or political meanings in a given local context—in order to make sense of the complexities and challenges of DNA testing in practice. We show that DNA testing is not just a technology of belonging or a way to claim citizenship rights. It may also enable exclusion and denial of rights. (shrink)
