The acquisition of virtue can be conceptualized as a self-regulatory process in which deliberate practice results in increasingly higher levels of skillfulness in leading a virtuous life. This conceptualization resonates with philosophical virtue theories as much as it converges with psychological models about skill development, expertise, goal motivation, and self-regulation. Yet, the conceptualization of virtue as skill acquisition poses the crucial question of motivation: What motivates individuals to self-improvement over time so that they can learn from past experience, correct mistakes, (...) and expand their ethical knowledge to new and unfamiliar circumstances? In this paper, it is argued that the motivation to increase one’s level of skillfulness in leading a virtuous life is supported by a specific identity goal, namely the goal to be a moral person. However, this moral identity goal needs to carry specific goal characteristics in order to effectively provide this motivation. It needs to be sufficiently abstract, internally motivated and promotion- rather than prevention-oriented. Research in developmental psychology suggests that the moral identity of children is rather concrete, externally motivated, and prevention-oriented. With development, higher levels of abstraction, internal motivation, and promotion-orientation gain importance providing an important motivational basis for a self-regulated process of virtue acquisition.

Consciousness is targeted by both philosophers and neuroscientists; but different methodological premises and even different conceptions about what conscious experience is and how the challenges and potential problems associated with consciousness research should be formulated underlie the different approaches. Namely, whereas empirical data and the constant refinement of experimental procedures to expand and modify this body of empirical data and resulting empirical theories are crucial to neuroscience, the significance of empirical knowledge to philosophy is less clear: Although empirical data certainly (...) can influence philosophical concepts, the latter are nonetheless prerequisites of empirical research itself and thus may themselves not be empirically testable. The present paper elaborates from a multidisciplinary, neuroscientist-philosopher’s perspective the relation of philosophical concepts and empirical research on consciousness, drawing on two exemplary controversies from the philosophy of mind – on the ontological status of experiential properties and on free will. Consequences from both the scientific and the philosophical standpoint are discussed. (shrink)

León and Zahavi (2023) have made a compelling case for the necessity of philosophy — and not only neuroscience — for investigating consciousness. In particular, they argue that any theory of consciousness cannot avoid philosophical enquiry and thus only can choose between good or bad philosophy. Also, the topics of self-consciousness and selfhood are highlighted as problems of consciousness sui generis next to the mind–body problem. I will try to elucidate a bit more the specific approaches to consciousness that philosophy (...) and neuroscience take and thus elaborate why the philosophy and the neuroscience of consciousness are complimentary rather than mutually exclusive.

In this article we introduce the concept of implied optical perspective in deep learning computer vision systems. Taking the BBC's experimental television programme “Made by Machine: When AI met the Archive” as a case study, we trace a conceptual and material link between the system used to automatically “watch” the television archive and a specific type of photographic practice. From a computational aesthetics perspective, we show how deep learning machine vision relies on photography, its technical regimes and epistemic advantages, and (...) we propose a novel way to identify the latent camera through which the BBC archive was seen by machine.

In 1961, Ernst Mayr published a highly influential article on the nature of causation in biology, in which he distinguished between proximate and ultimate causes. Mayr argued that proximate causes (e.g. physiological factors) and ultimate causes (e.g. natural selection) addressed distinct ‘how’ and ‘why’ questions and were not competing alternatives. That distinction retains explanatory value today. However, the adoption of Mayr’s heuristic led to the widespread belief that ontogenetic processes are irrelevant to evolutionary questions, a belief that has (1) hindered (...) progress within evolutionary biology, (2) forged divisions between evolutionary biology and adjacent disciplines and (3) obstructed several contemporary debates in biology. Here we expand on our earlier (Laland et al. in Science 334:1512–1516, 2011) argument that Mayr’s dichotomous formulation has now run its useful course, and that evolutionary biology would be better served by a concept of reciprocal causation, in which causation is perceived to cycle through biological systems recursively. We further suggest that a newer evolutionary synthesis is unlikely to emerge without this change in thinking about causation. (shrink)

Depression is a highly recurrent disorder with limited treatment alternatives for reducing risk of subsequent episodes. Acceptance and commitment therapy (ACT) and attention bias modification (ABM) separately have shown some promise in reducing depressive symptoms. This study investigates (a) if group-based ACT had a greater impact in reducing residual symptoms of depression over a 12-month follow-up than a control condition, and (b) if preceding ACT with ABM produced added benefits. This multisite study consisted of two phases. In phase 1, participants (...) with a history of depression, currently in remission (N= 244), were randomized to either receive 14 days of ABM or a control condition. In phase 2, a quasi- experimental design was adopted, and only phase-1 participants from the Sørlandet site (N= 124) next received an 8-week group-based ACT intervention. Self-reported and clinician-rated depression symptoms were assessed at baseline, immediately after phase 1 and at 1, 2, 6, and 12 months after the conclusion of phase 1. At 12-month follow-up, participants who received ACT exhibited fewer self-reported and clinician-rated depressive symptoms. There were no significant differences between ACT groups preceded by ABM or a control condition. There were no significant differences between ACT groups preceded by ABM or a control condition. Group-based ACT successfully decreased residual symptoms in depression over 12 months, suggesting some promise in preventing relapse. (shrink)

We use Marya Schechtman’s Narrative Self-Constitution View to support the widespread idea that food can contribute to the construction and expression of our identities and be used to understand others. What foods we consume can be one such way to construct our identities as food itself can have different values: ethically sourced, healthy, culturally significant, etc. However, the ability to constitute one’s own identity in this way depends on the ability to autonomously choose what we consume. We argue that most (...) consumers have much less control over their own consumption habits than is typically assumed (indeed, much of the literature on food and identity relies on the assumption) and thus consumers have diminished autonomy with respect to identity-constitution. We focus on the effects of three such autonomy compromising practices: food impositions, which are social pressures on food choice; manipulative marketing; and impediments to access. Together these practices diminish second-order endorsement of food-related values, generate false beliefs about what one is eating, and create social, economic, or physical barriers which limit access to desired foods. There are, however, spaces where consumers are fighting back against cultural norms and agribusiness and changing their own relationship(s) with consumption, thereby exercising increased autonomy over their food and their identity.

While many studies from analytical sociology apply agent-based modeling to analyze the transformational mechanisms linking the micro to the macro level, we hold the view that both situational and action formation mechanisms can rather be unveiled by means of more advanced quantitative methods. By focusing on selective exposure to quality newspapers, our study has both an analytical and a substantive aim. First., our analytical aim is to amend the psychological mechanism of avoiding cognitive dissonance by social mechanisms allowing postulates on (...) how the selective exposure effect might vary by particular social groups. Second, our substantive aim is to set the ground for a longitudinal analysis of selective exposure to quality papers by placing these social mechanisms in the context of social and cultural change. By referring to hypothetical data, we illustrate which kind of (multilevel) moderator effects would have to hold if our hypotheses were true. (shrink)

Tradition und Traditionsbruch gehören zu den entscheidenden Herausforderungen in einer beschleunigt zusammenwachsenden Welt. Sollen beide Seiten nicht in einem unfriedlichen Antagonismus verharren, so ist Prämissentransparenz und Grenzbestimmung der je eigenen und fremden Argumente gefragt. In der Auseinandersetzung mit klassischen Quellen der europäischen und außereuropäischen Philosophiegeschichte soll der vorliegende Band zeigen, daß Selbstkritik und Selbstaffirmation in allen Weltphilosophien nur mehr zwei entgegengesetzte Reaktionen auf eine von innen oder von außen gefährdete Identität zum Ausdruck bringen. Skepsis und Dogmatik betreffen darum nicht allein (...) den Kern der abendländischen Annäherungen, sondern sie treffen den Nerv aller Weltphilosophien gleichermaßen. Skeptisch-kritische Positionen prägen ebenso die buddhistische, taoistische und islamische Philosophie; spekulativ-systematische Ansätze finden ihren Niederschlag in der islamischen, der hinduistischen wie auch der europäischen Philosophie; rationalistische und analytische Strömungen lassen sich in allen genannten philosophischen Traditionen ausfindig machen. Leitend ist darum die gemeinsame Frage: Wie ist Identitätskonstruktion in Traditionen möglich, ohne dogmatisch zu werden, und wie können Relativität und Skepsis ihre produktive Funktion entfalten, ohne auf die Universalität der Werte (wie etwa der Menschenrechte) verzichten zu müssen?

The era of ‘big data’ studies and computational social science has recently given rise to a number of realignments within and beyond the social sciences, where otherwise distinct data formats – digital, numerical, ethnographic, visual, etc. – rub off and emerge from one another in new ways. This article chronicles the collaboration between a team of anthropologists and sociologists, who worked together for one week in an experimental attempt to combine ‘big’ transactional and ‘small’ ethnographic data formats. Our collaboration is (...) part of a larger cross-disciplinary project carried out at the Danish Technical University, where high-resolution transactional data from smartphones allows for recordings of social networks amongst a freshman class. With a parallel deployment of ethnographic fieldwork among the DTU students, this research set-up raises a number of questions concerning how to assemble disparate ‘data-worlds’ and to what epistemological and political effects? To address these questions, a specific social event – a lively student party – was singled out from the broader DTU dataset. Our experimental collaboration used recordings of Bluetooth signals between students’ phones to visualize the ebb and flow of social intensities at the DTU party, juxtaposing these with ethnographic field-notes on shifting party atmospheres. Tracing and reflecting on the process of combining heterogeneous data, the article offers a concrete case of how a ‘stitching together’ of digital and ethnographic data-worlds might take place.

Veissière et al. disrupt current debates over the nature of mindreading by bringing multiple positions under the umbrella of free-energy. However, it is not clear whether integrating the opposing sides under a common formal framework will yield new insights into how mindreading is achieved, rather than offering a mere redescription of the target phenomenon.

BackgroundResponsive neurostimulation has been utilized as a treatment for intractable epilepsy. The RNS System delivers stimulation in response to detected abnormal activity, via leads covering the seizure foci, in response to detections of predefined epileptiform activity with the goal of decreasing seizure frequency and severity. While thalamic leads are often implanted in combination with cortical strip leads, implantation and stimulation with bilateral thalamic leads alone is less common, and the ability to detect electrographic seizures using RNS System thalamic leads is (...) uncertain.ObjectiveThe present study retrospectively evaluated fourteen patients with RNS System depth leads implanted in the thalamus, with or without concomitant implantation of cortical strip leads, to determine the ability to detect electrographic seizures in the thalamus. Detailed patient presentations and lead trajectories were reviewed alongside electroencephalographic analyses.ResultsAnterior nucleus thalamic leads, whether bilateral or unilateral and combined with a cortical strip lead, successfully detected and terminated epileptiform activity, as demonstrated by Cases 2 and 3. Similarly, bilateral centromedian thalamic leads or a combination of one centromedian thalamic alongside a cortical strip lead also demonstrated the ability to detect electrographic seizures as seen in Cases 6 and 9. Bilateral pulvinar leads likewise produced reliable seizure detection in Patient 14. Detections of electrographic seizures in thalamic nuclei did not appear to be affected by whether the patient was pediatric or adult at the time of RNS System implantation. Sole thalamic leads paralleled the combination of thalamic and cortical strip leads in terms of preventing the propagation of electrographic seizures.ConclusionThalamic nuclei present a promising target for detection and stimulation via the RNS System for seizures with multifocal or generalized onsets. These areas provide a modifiable, reversible therapeutic option for patients who are not candidates for surgical resection or ablation. (shrink)

Words whose consonantal articulation places move from the front of the mouth to the back (e.g. BADAKA; inward) receive more positive evaluations than words whose consonantal articulation places move from the back of the mouth to the front (e.g. KADABA; outward). This in–out effect has a variety of affective, cognitive, and even behavioural consequences, but its underlying mechanisms remain elusive. Most recently, a linguistic explanation has been proposed applying the linguistic easy-first account and the so-called labial-coronal effect from developmental speech (...) research and phonology to the in–out effect: Labials (front) are easier to process than coronals (middle); and people prefer easy followed by harder motor components. Disentangling consonantal articulation direction and articulation place, the present three preregistered experiments (total N = 1012) found in–out effects for coronal-dorsal (back), and labial-dorsal articulation places. Critically, no in–out effect emerged for labial-coronal articulation places. Thus, the in–out effect is unlikely an instantiation of easy first. (shrink)

How does talk work, and can we engage the public in a dialogue about the scientific study of talk? This article presents a history, critical evaluation and empirical illustration of the public science of talk. We chart the public ethos of conversation analysis that treats talk as an inherently public phenomenon and its transcribed recordings as public data. We examine the inherent contradictions that conversation analysis is simultaneously obscure yet highly cited; it studies an object that people understand intuitively, yet (...) routinely produces counter-intuitive findings about talk. We describe a novel methodology for engaging the public in a science exhibition event and show how our ‘conversational rollercoaster’ used live recording, transcription and public-led analysis to address the challenge of demonstrating how talk can become an informative object of scientific research. We conclude by encouraging researchers not only to engage in a public dialogue but also to find ways to actively engage people in taking a scientific approach to talk as a pervasive, structural feature of their everyday lives.

On May 18, 1958, Martin Heidegger led a one-day colloquium in Freiburg on the topic of “Art and Thinking” together with Shin’ichi Hisamatsu, the Japanese philosopher and Buddhist scholar. The protocol of the colloquium, published in volume 16 of Heidegger’s Gesamtausgabe, presents a conversation among the colloquium participants about art in the East Asian world. In this conversation, Heidegger is particularly interested in hearing from Hisamatsu about the conception of art present in the East Asian world prior to the introduction (...) of Western aesthetic concepts and about the relationship between form and formlessness in East Asian aesthetics. The conversation allows Hisamatsu to clarify for the participants what he takes to be the most essential features of Zen art and how these features compare with those found in modern Western abstract art.

Recent studies have shown that population-level time perspectives can be approximated using “big data” on search engine queries, and that these indices, in turn, predict the per-capita Gross Domestic Product of countries. Although these findings seem to support Baumard's suggestion that affluence makes people more future-oriented, they also reveal a more complex relationship between time perspectives and economic outputs.

Physical environmental factors – or ‘artifacts’ – are linked to healthcare outcomes in the field of social psychology. However, the role of artifacts remains rarely examined in the burgeoning discipline of placebo studies. In this paper, we argue that a careful consideration of artifacts – such as provider clothing and office décor – may carry significant potential in eliciting placebo effects in clinical settings. We discuss three potential mechanisms by which artifacts may enhance or diminish placebo (or nocebo) effects: classical (...) conditioning, response expectancy, and mindsets. We propose testable hypotheses and conclude by providing innovative research designs that might help to better advance this novel research agendum. (shrink)

The defense of plants against herbivores and pathogens involves the participation of an enormous range of different metabolites, some of which act directly as defensive weapons against enemies (toxins or deterrents) and some of which act as components of the complex internal signaling network that insures that defense is timed to enemy attack. Recent work reveals a surprising trend: The same compounds may act as both weapons and signals of defense. For example, two groups of well‐studied defensive weapons, glucosinolates and (...) benzoxazinoids, trigger the accumulation of the protective polysaccharide callose as a barrier against aphids and pathogens. In the other direction, several hormones acting in defense signaling (and their precursors and products) exhibit activity as weapons against pathogens. Knowing which compounds are defensive weapons, which are defensive signals and which are both is vital for understanding the functioning of plant defense systems. (shrink)

The role of nonverbal communication in patients with post-stroke language impairment (aphasia) is not yet fully understood. This study investigated how aphasic patients perceive and produce co-speech gestures during face-to-face interaction, and whether distinct brain lesions would predict the frequency of spontaneous co-speech gesturing. For this purpose, we recorded samples of conversations in patients with aphasia and healthy participants. Gesture perception was assessed by means of a head-mounted eye-tracking system, and the produced co-speech gestures were coded according to a linguistic (...) classification system. The main results are that meaning-laden gestures (e.g., iconic gestures representing object shapes) are more likely to attract visual attention than meaningless hand movements, and that patients with aphasia are more likely to fixate co-speech gestures overall than healthy participants. This implies that patients with aphasia may benefit from the multimodal information provided by co-speech gestures. On the level of co-speech gesture production, we found that patients with damage to the anterior part of the arcuate fasciculus showed a higher frequency of meaning-laden gestures. This area lies in close vicinity to the premotor cortex and is considered to be important for speech production. This may suggest that the use of meaning-laden gestures depends on the integrity of patients’ speech production abilities. (shrink)

Biobanking in Europe has made major steps towards harmonization and shared standards for the collection and processing of data and samples stored in biobanks. Still, biobanks and researchers face substantial legal difficulties in the field of data protection and sample management. Data protection law was harmonized almost 15 years ago while rights in samples fall under the competence of the Member States of the EU. Despite the Data Protection Directive the field of data protection shows a substantial degree of deviation (...) as public health was excluded from the harmonization. Biobanks seem to have substantially fewer difficulties to cope with in terms of the legal requirements in the field of sample management. This paper discusses the legal framework, experiences of different biobanks in Europe and potential ways forward. It also highlights the need for a health economic analysis of the costs and benefits of privacy protection in Europe. At the moment, policymakers seem to build their decisions on an insufficient evidence base which underestimates the potential value of biobanks for European public health. Within the past few years little progress has been achieved with regards to the development of a unified legal framework in Europe, The diversity in the legal system is also reflected in the different approaches of ethics committees towards biobanking. To secure the responsible and effective use of data and samples, more efforts are needed to come up with pathways for a solution. (shrink)

Alfred North Whitehead bietet in seiner philosophischen Kosmologie einen Deutungsrahmen, mit dem Wirklichkeit primär von ihrer Prozesshaftigkeit begriffen werden kann. Eine solche prozesshafte Konzeption der Wirklichkeit hat folgerichtig auch Auswirkungen darauf, wie Religion und damit zusammenhängend das Gott-Welt-Verhältnis gedacht wird. Der Band möchte einen Beitrag zu einer systematischen Rekonstruktion von Whiteheads Religionstheorie und -philosophie leisten und zugleich zeigen, wie ihr Potential für die aktuelle Debatte fruchtbar gemacht werden kann.

The book (in German) on “Solar Energy – challenge for research, development and international co-operation” is the report of a study group of the Akademie der Wissenschaften zu Berlin. It reviews solar thermal, photovoltaic, and bio mimetic solar energy techniques; prospects of de-central techniques in developing countries; transport and storage of solar energy; and chances for cooperation with Arabic countries and countries of the South of the former Soviet Union. The prospect of large scale energy production in arid areas, and (...) the modern potentials of conducting electricity over long distances by high-voltage DC transmission (V, 2.1) are particularly relevant for the concluding section. Political chances as well as risks were considered for reliable long term cooperation with various Arab countries on these issues. The recommendations appear to be still appropriate 25 years after the book was published, particularly the political advice in favour of cooperation between Europe and suitable countries of the Maghreb. The global time scale of implementation (discussed in chapter I, 7.2) is of the same (high) magnitude as that of other major changes in the history of technology, such as the substitution of sailing ships by steamboats which took almost a century.

The serotonin transporter plays an important role in regulating serotonergic transmission via removal of serotonin from synaptic clefts. Alterations in 5-HTT expression and subsequent 5-HT transmission have been found to be associated with changes in behaviour, such as fearfulness or activity, in humans and other vertebrates. In humans, alterations in 5-HTT expression have been suggested to be able to lead to better learning performance, with more fearful persons being better at learning. Similar effects of the variation in the 5-HTT on (...) fearfulness have been found in chickens, and in this study, we investigated effects on learning. Therefore, we tested 52 adult laying hens, differing in their functional 5-HTT genotype in an operant learning paradigm in three different phases and in a tonic immobility test for fearfulness. We found that the 5-HTT polymorphism affects the initial learning performance of laying hens, with homogeneous wild-type hens being the slowest learners, and the most fearful birds. W/W hens, showed significantly more choices to solve the initial learning task and had the highest latencies in a tonic immobility test, indicating the highest fearfulness. Our results provide interesting first insights into the role of 5-HTT in chickens and its sensitive interaction with the environment. We further suggest that the 5-HTT gene can be an interesting target gene for future breeding strategies as well as for further experimental studies. (shrink)

Definition of the problemMedical and nursing care often takes place within complex organizational structures that comprise numerous facilities at numerous locations. We introduce an interactive ethical concept, designed in cooperation with the diaconal foundation BruderhausDiakonie Reutlingen and the International Centre for Ethics in Science, University of Tübingen, to address the particular needs of such organizations.ArgumentsTherefore we portray the interactive Nijmegen Model which combines an ethics committee located at the management level and situational ethical case deliberations on the ward in order (...) to bring together two indispensable ways of ethical reflection in organizations: “top-down”/“bottom-up”. We illustrate the challenges of implementing the said model into the organizational construction of the BruderhausDiakonie and how to address these by means of conception and implementation.ConclusionConsidering the implementational challenges that we encountered, the Nijmegen Model needs to be enhanced by introducing a link between the committee and the case deliberations. We delineate the basic elements and the requirements for such a position while reporting our initial practical experience with this model. (shrink)

Background: Multiple studies have shown that people who have experienced a serious health problem such as an injury tend to overrate the quality of health they had before that event. The main objective of this study was to test whether the phenomenon of respondents overrating their past health can also be observed in people from the general population. A second aim was to test whether habitual optimism is indeed focused on events in the future.Method: A representatively selected community sample from (...) Leipzig, Germany was examined. Respondents were asked to assess their current health, their past health, and their expected future health on a 0–100 scale. In addition, the study participants completed several questionnaires on specific aspects of physical and mental health.Results: Respondents of all age groups assessed their health as having been better in the past than it was at present. Moreover, they also assessed their earlier state of health more positively than people 5 years younger did their current state. Habitual optimism was associated with respondents having more positive expectations of how healthy they will be in 5 years time, but the correlation with their assessments of their current health was nearly as high.Conclusion: Highly positive scores of retrospectively assessed health among people who have experienced a health problem cannot totally be accounted for by a response to that health problem.
