This essay is concerned with the epistemic roles of error in scientific practice. Usually, error is regarded as something negative, as an impediment or obstacle for the advancement of science. However, we also frequently say that we are learning from error. This common expression suggests that the role of error is not—at least not always—negative but that errors can make a fruitful contribution to the scientific enterprise. My paper explores the latter possibility. Can errors play an epistemically productive role in (...) scientific research? The paper begins with a review of several twentieth-century approaches to error and the various agendas behind them. It is shown that only very few scholars have considered whether errors can be productive. The main part of the paper examines a concrete debate in early nineteenth-century microscopy and analyses how the microscopists coped with the problem of error. Drawing on this material, the article offers some terminological clarifications of the common notion ‘learning from error’. The conclusion argues that error can indeed play epistemically productive roles in scientific practice.Keywords: Error; Nineteenth-century microscopic anatomy. (shrink)

This introduction to the special issue of the same title sets out the context for a critical examination of contemporary developments in sociotechnical systems deployed in the name of security. Our focus is on technologies of tracking, with their claims to enable the identification of those who comprise legitimate targets for the use of violent force. Taking these claims as deeply problematic, we join a growing body of scholarship on the technopolitical logics that underpin an increasingly violent landscape of institutions, (...) infrastructures, and actions, promising protection to some but arguably contributing to our collective insecurity. We examine the asymmetric distributions of sociotechnologies of security; their deadly and injurious effects; and the legal, ethical, and moral questions that haunt their operations. (shrink)

Depression is a disorder of impaired emotion regulation. Consequently, examining individual differences in the habitual use of emotion-regulation strategies has considerable potential to inform models of this debilitating disorder. The aim of the current study was to identify cognitive processes that may be associated with the use of emotion-regulation strategies and to elucidate their relation to depression. Depression has been found to be associated with difficulties in cognitive control and, more specifically, with difficulties inhibiting the processing of negative material. We (...) used a negative affective priming task to assess the relations among inhibition and individual differences in the habitual use of rumination, reappraisal, and expressive suppression in clinically depressed, formerly depressed, and never-depressed participants. We found that depressed participants exhibited the predicted lack of inhibition when processing negative material. Moreover, within the group of depressed participants, reduced inhibition of negative material was associated with greater rumination. Across the entire sample, reduced inhibition of negative material was related to less use of reappraisal and more use of expressive suppression. Finally, within the formerly depressed group, less use of reappraisal, more use of rumination, and greater expressive suppression were related to higher levels of depressive symptoms. These findings suggest that individual differences in the use of emotion-regulation strategies play an important role in depression, and that deficits in cognitive control are related to the use of maladaptive emotion-regulation strategies in this disorder.

: This article analyzes the transformation of epistemological and methodological discourses in German microscopy. It is argued that the expansion of microscopy in the early decades of the nineteenth century was pivotal for the emergence of intricate methodologies that characterized the instruments and methods of microscopy in new ways. Close examination of these means of investigation showed them to be intrinsically imperfect. The flaws of the instrument, the faults of the observer's eyes and the obstructive power of the objects of (...) investigation actions came to be crucial issues in epistemological and methodological debates. It became clear that the particulars of the research arrangement not only limited the range of possible microscopical observations but would always impede and interfere with the results: Perfect working conditions could never be achieved.

The ability to process center‐embedded structures has been claimed to represent a core function of the language faculty. Recently, several studies have investigated the learning of center‐embedded dependencies in artificial grammar settings. Yet some of the results seem to question the learnability of these structures in artificial grammar tasks. Here, we tested under which exposure conditions learning of center‐embedded structures in an artificial grammar is possible. We used naturally spoken syllable sequences and varied the presence of prosodic cues. The results (...) suggest that mere distributional information does not suffice for successful learning. Prosodic cues marking the boundaries of the major relevant units, however, can lead to learning success. Thus, our data are consistent with the hypothesis that center‐embedded syntactic structures can be learned in artificial grammar tasks if language‐like acoustic cues are provided. (shrink)

Mueller et al. discuss the role of acoustic cues in detecting language structure more generally. Across languages, there are clear links between acoustic cues and syntactic structure. They show that AGL experiments implementing analogous links demonstrate that prosodic cues, as well as various auditory biases, facilitate the learning of structural rules. Some of these biases, e.g. for auditory grouping, are also present in other species.

Die Reihe "Studien interdisziplinäre Geschlechterforschung" präsentiert regelmäßig neuere Untersuchungen über Herausbildungen und Bedeutungen von Geschlecht. Verknüpft werden natur-, technik-, sozial- und kulturwissenschaftliche Sichtweisen. Ebenfalls thematisiert werden hochschulpolitische Entwicklungen und Perspektiven von Geschlechterforschung in und außerhalb der Hochschule. Die Reihe wird herausgegeben vom Zentrum für interdisziplinäre Frauen- und Geschlechterforschung an der Carl von Ossietzky Universität Oldenburg (ZFG) und dem Zentrum für feministische Studien, Universität Bremen (ZFS). In diesem Band: In unserer heutigen Technowissenschaftskultur ist die Frage nach dem Verhältnis von Körper und (...) Maschine zentral. Während Körper denaturalisiert und durch die Life- und Cyberscience als turbulent und dynamisch reformuliert werden, wird Maschinen Sozialität zu- und eingeschrieben. An Beispielen aus der Robotik, Embodied Agents-Forschung und anderen Technowissenschaften, mit Bezug auf Philosophie, Wissenschaftsforschung und Literatur wird gezeigt, wie sich transklassische Maschinen und post-humane Körper herausbilden und geschlechtlich neu kodiert werden.

This paper discusses two methodological notions, the concepts Gegenprobe (countercheck) and Gegenversuch (counter-trial), which were widely applied, discussed, relied upon, and defended in German-language writings about empirical inquiry. In the decades around 1800, they were common in physiology; medicine; agriculture; chemistry; various technologies, such as printing, metallurgy, and mining; accounting; and legal and political argumentation. The ubiquity of those concepts signals a broad concern with securing empirical findings and empirical knowledge. Gegenproben and Gegenversuche – the terms as well as the (...) practices – are evidence for the close connection among explicitly knowledge-seeking endeavors and crafts and technologies. Physiological experiments, chemical analyses, agricultural or vaccination trials were indebted to applied and practical procedures of making and assaying. What united these different fields was the fact that the problems that had to be solved were very complex yet at the same time of immediate relevance to everyday lives (like diseases or crops) or highly controversial (like vital forces or spontaneous generation). We know that late eighteenth-century and early nineteenth-century practices of inquiry were firmly embedded in applied, technical contexts; this essay shows that methodological notions were anchored in applied, technical contexts as well.

This article sets out to provide a conceptual contribution to theoretical and empirical work on the level of media repertoires. We will first discuss theoretical approaches which allow for an explanation of media repertoires and relate them to the most prominent approaches to selective audience behavior. Secondly, in order to empirically analyze media repertoires we propose a combination of secondary analyses of existing surveys on media use and qualitative studies on the internal ‘architecture’ of these repertoires and their practical meaning (...) in the user's everyday life. These proposals for secondary analyses are illustrated by two examples based on different data sets and referring to different levels of analysis. (shrink)

Summary The first systematic studies on the velocity of chemical reactions (now called reaction rates) were published in the 1850s and 1860s. Inquiring about the course of chemical change, their authors established empirical equations on the basis of their measurement results. But these laws, which represented reaction velocities as proportional to the actual concentration of the reagents, could not be given a physical foundation. The chemists themselves regarded their propositions as mere ad hoc hypotheses. In 1867 Leopold Pfaundler formulated a (...) qualitative theory of chemical processes based on Clausius's version of the kinetic gas theory (and more specifically on his theory of evaporation), and on Saint-Claire Deville's investigations of dissociation processes. Pfaundler's theory was based on farreaching analogies: between evaporation and dissociation; between the gaseous state and the activated state; and between evaporation- and chemical-equilibrium. Four points of Pfaundler's theory must be regarded as essential: (1) the reduction of chemical change to randomly occurring molecular collisions, only showing regularities in great numbers according to the laws of probability; (2) the idea that molecules are in different states of internal and external motion, which determines whether a collision results in a reaction; (3) the view of the reaction step as a transition from internal to external motion and vice versa; and (4) the introduction of a new molecular-kinetic definition of chemical affinity as the maximum of internal motion. With these assumptions, Pfaundler provided the empirical rate equations with a new statistical interpretation and a physical Justification. (shrink)

This volume thus clears the ground for the productive and fruitful integration of these new developments into philosophy of science.

This essay offers some reflections on the recent history of the disputes about the relation between history and philosophy of science (HPS) and the merits and prospects of HPS as an intellectual endeavor. As everyone knows, the issue was hotly debated in the 1960s and 1970s. That was the hey-day of the slogan "history without philosophy of science is blind, philosophy without history of science is empty" as well as of the many variations on the theme of HPS as a (...) "marriage of convenience," "intimate relation," or "marriage for the sake of reason." There was a flurry of interest in the early 1990s, as evidenced by sections in the 1992 and 1994 issues of PSA, entitled: "Do the History of Science and the Philosophy of .. (shrink)

In recent developments in Artificial Intelligence and especially in robotics we can observe a tendency towards building intelligent artefacts that are meant to be social, to have ‘human social’ characteristics like emotions, the ability to conduct dialogue, to learn, to develop personality, character traits, and social competencies. Care, entertainment, pet and educational robots are conceptualised as friendly, understanding partners and credible assistants which communicate ‘naturally’ with users, show emotions and support them in everyday life. Social robots are often designed to (...) interact physically, affectively and socially with humans in order to learn from them. To achieve this goal, roboticists often model the human‐robot interaction on early caregiver‐infant interactions. In this paper I want to analyse prominent visions of these ‘socio‐emotional’ machines as well as early prototypes and commercial products with regard to the human‐machine interface. By means of this I will ask how feminist critiques of technology could be applied to the field of social robotics in which concepts like sociality or emotion are crucial elements while, at the same time, these concepts play an important role in feminist critiques of technology.

A multitude of techno-natures emerge through discourses and practices of the new technosciences. While some philosophers and science studies scholars argue that model organisms and artefacts are getting more and more disembodied and decontextualised in the laboratory, I want to show how ontic dimensions of model organisms and artefacts are made invisible as well as visible in different practices of technosciences like Artificial Life and robotics.This analysis opens up possibilities for an understanding of how ontic dimensions of non-human actors are (...) made visible and invisible in technoscientific practices. At the same time it allows the development of a concept of nonhuman actors beyond reifying, velontriquist practices of representation as well as a critical intervention in the co-construction of our technoculture. German Mannigfaltige Techno-Naturen an der Schnittstelle von Sozialem, Technischem und Natürlichem entstehen in den und durch die Diskurse und Praktiken der neuen Technowissenschaften. Entgegen der verbreiteten These von der Entkörperung und Dekontextualisierung von Modellorganismen im Labor zeige ich in meinem Beitrag auf, wie auf je unterschiedliche Weise ontische Dimensionen von Modellorganismen und Technofakten in der Artificial Life-Forschung und Robotik sichtbar bzw. unsichtbar gemacht werden.Gerade die Untersuchung der Konstruktion der ontischen Dimension nichtmenschlicher Akteure in unterschiedlichen Forschungspraktiken eröffnet Möglichkeiten, nichtmenschliche Akteure ernst zu nehmen, erlaubt ein genaueres Verständnis des Un/Sichtbarmachens von spezifischen ontischen Dimensionen nichtmenschlicher Akteure und zeigt Wege für kritische Interventionen in unsere Technowissenschaftskultur auf. Sie vermeidet jene bauchrednerischen Erzählpraktiken, die mit der Stimme aus dem Off den nichtmenschlichen Akteuren Eigenschaften verordnen und sie damit einmal mehr zum Verstummen bringen. (shrink)

Cognitive control processes, such as updating task-relevant information while switching between multiple tasks, are substantially impaired in older adults. However, it has also been shown that these cognitive control processes can be improved by training interventions, e.g., by training in task switching. Here, we applied an event-related potential approach to identify whether a cognitive training improves task-preparatory processes such as updating of relevant task goals. To do so, we applied a pretest-training-posttest design with eight training sessions. Two groups of older (...) adults were either trained in task switching or in performing single tasks and we compared their performance to a group of untrained younger adults. To foster cue updating in the treatment group, we applied a cue-based switching task in which the two task cues were randomly selected prior to target presentation so that participants had time to prepare for the upcoming task. In contrast, the control group also received task cues but those were redundant as only one task had to be performed. We also examined whether training in cue updating during task switching can be transferred to a similar cognitive control task measuring updating of context information, namely a modified version of the AX-Continuous Performance Task. The results revealed training-specific improvements in task switching, that is, a larger improvement in blocks requiring switching in comparison to single tasks at the behavioral level. In addition, training specific-effects were also found at the neuronal level. Older adults trained in cue updating while switching showed a reduction in mixing costs in the cue-related P3, indicating an improvement in preparatory updating processes. Additionally, P3 topography changed with training from a very broad to a parietally focused scalp distribution similar to the one found in younger adults. However, we did not obtain training-specific improvements in context updating in the AX-CPT neither at the behavioral level nor at the neuronal level. Results are discussed in the context of the ongoing debate on whether transfer of cognitive training improvements is possible. (shrink)

This article compares investigations of the process of vision that were made in early nineteenth-century Britain and the German lands. It is argued that vision studies differed significantly east and west of the North Sea. Most of the German investigators had a medical background and many of them had a firm grasp of contemporary philosophy. In contrast, the British studies on vision emerged from the context of optics. This difference manifested itself in the conceptual tools for the analysis of vision, (...) deception and illusion and shaped the experiments on visual phenomena that were carried out. Nevertheless, both in Britain and in the German lands vision studies were driven by the same impetus, by epistemological concerns with the nature and reliability of knowledge acquisition in experience. The general epistemological conclusions drawn from researches on vision and deception were optimistic. Precisely because mechanisms of deception and illusion could be uncovered, the possibility of acquiring empirical knowledge could be secured. (shrink)

This paper discusses the claim that science is “messy.” Part I argues first, that a good portion of today’s discussions about messy science is just a portrayal of familiar features of science in new terms. In the paper, I refer to this as “messy science talk.” Second, Part I draws out rhetorical functions of messy science talk, namely the denigration of science in the popular media and the celebration of the maverick. Part II identifies one way in which it is (...) enlightening to think about mess in current science, namely in reference to the problems that scientists need to address. It also shows that we do not need an entirely new conceptual inventory to analyze these problems. “Mess” and “wicked problems” were a theme in operations research and theories of social planning in the 1970s. These older analyses can illuminate important characteristics of today’s scientific problems. Wicked problems cut across different disciplines, engage different stakeholders (including non-scientists), are fluid, and cannot even be clearly formulated. They are urgent and need to be addressed before sufficient evidence is in. (shrink)

Risk assessment is an evidence-based analytical framework used to evaluate research findings related to environmental and public health decision-making. Different routines have been adopted for assessing the potential risks posed by substances and products to human health. In general, the traditional paradigm is a hazard-driven approach, based on a monocausal toxicological perspective. Questions have been raised about the applicability of the general chemical risk assessment approach in the specific case of nanomaterials. Most scientists and stakeholders assume that the current standard (...) methods are in principle suitable, but point out that experimental aspects and practical guidelines need specific adaptations. Beyond this laboratory level, risk assessment of nanomaterials also faces a number of substantive and procedural limitations, which are intrinsically attributed to the general orthodoxy of the risk assessment concept. Moreover, the developed formalism used to organize scientific knowledge is closely interlinked with the underlying governance design and the mode of interaction between the two spheres of ‘science’ and ‘decisions’. This contribution will provide a closer look at the evolution of different institutional settings for risk assessment in the context of decision-making. Improved risk governance frameworks with different narratives, process designs and procedural elements will be compared. The question of a general principle of enhanced organization of risk assessment will be discussed taking account of the barriers of substantive and procedural limitations in the special case of nanomaterials.

In Extragalactic Reality: The Case of Gravitational Lensing Hacking resumes the discussion of scientific realism from the last chapter of Representing and Intervening. Since the criterion of manipulability cannot be applied to astronomical objects, experimental entity realism seems to be restricted to terrestrial entities. In fact, Hacking explicitly argues against astronomical realism. The case at issue is the existence of gravitational lenses. In this paper, I question Hacking 's chief witness for astronomical antirealism: the gravitational lens system “0957+ 561”. It (...) will be shown that Hacking 's argumentation is misleading. Discussing astronomical realism as theory realism, Hacking focuses on the question of how to infer the existence of gravitational lenses from the truth of gravitational lens theory. But neither the reconstruction of gravitational lensing in terms of inference to the best explanation nor the argument of underdetermination are tenable under closer inspection. My thesis is that a realist account of gravitational lensing can be given by relying on observation, causal capacities and home truths. (shrink)

The published HPS paper gives us only an insufficient idea of the project of integrating history and philosophy of science. To understand how the integration may work and to make it even more rewarding, we need to reflect on the very process of constructing theories of the epistemic features of science. My paper develops this claim and considers its implications.

This paper examines how scientists conceptualize their research methodologies. Do scientists raise concerns about vague criteria and genuine uncertainties in experimental practice? If so, what sorts of issues do they identify as problematic? Do scientists acknowledge the presence of value judgments in scientific research, and do they reflect on the relation between epistemic and non-epistemic criteria for decisionmaking? We present findings from an analysis of qualitative interviews with 63 scientific researchers who talk about their views on good research practice. We (...) argue that analysts of science should care about scientists’ conceptualizations of the criteria and of the practical judgments that scientific inquiry involves. While scientists’ accounts of their own research methodologies alone do not give us a full picture of how science really works, they can point us to areas of concern. They can inspire and direct philosophical reflections about how science works. Throughout the interviews, the participating researchers provided specific examples from their own research contexts as illustrations of their methodological points. These examples reveal that scientists often struggle to evaluate the quality of their data, to figure out whether the available evidence confirms their hypothesis, whether a replication was successful, or to what extent they can rely on peer-reviewed papers. General ideas about good research methods do not directly translate into specific evaluation criteria or strategies that can guide research and help validate empirical data. (shrink)

While painted wooden icons of the Nursing Virgin were relatively common in fifteenth-century Ethiopia, only one miniature of the motif of the time has come to light. This image, bound into a later manuscript of the Miracles of Mary, is painted in a decidedly abstract style, comparable to other representations of the Virgin in fifteenth-century Ethiopian book illustration. Relying on Peirce’s distinction between index and icon, this article considers how such abstract representations might have been meant to evoke the divine (...) presence of Mary as a spiritual trace of the artist’s and the audience’s devotional practices, rather than as a potentially miracle-working depiction of her corporeal presence based on figural likeness, as was the case with painted wooden panels. Incorporating references to Ethiopian and Western theorists of modernity, the essay further proposes to view the multiple and interlocking mirror effects in book art as instances of second-order observation, in which, for example, the Virgin sees herself depicted in a book of her miracles, the compilation of which she commissioned and aided; the scribe and artist is featured in one of the miracles he himself is writing and illustrating; and the donor is depicted gazing at the viewer. Whether enabling skeptical distance or a more fully immersive spiritual experience undisturbed by attempts to capture corporeal likeness, or both, this essay proposes to analyze the politics and theology of abstraction in fifteenth-century Ethiopian book art by centering on a rare depiction of the Nursing Virgin.

This article presents a new framework for the analysis of experimental control. The framework highlights different functions for experimental controls in the realization of an experiment: experimental controls that serve as tests and experimental controls that serve as probes. The approach to experimental control proposed here can illuminate the constitutive role of controls in knowledge production, and it sheds new light on the notion of exploratory experimentation. It also clarifies what can and what cannot be expected from reviewers of scientific (...) journal articles giving feedback on experimental controls. (shrink)
