According to the traditional definition of lying, somebody lies if he or she makes a believed-false statement with the intention to deceive. The traditional definition has recently been challenged by non-deceptionists who use bald-faced lies to underpin their view that the intention to deceive is no necessary condition for lying. We conducted two experiments to test whether their assertions are true. First, we presented one of five scenarios that consisted of three different kinds of lies. Then we asked participants to (...) judge whether the scenario at hand was a lie, whether the speaker intended to deceive somebody, and how they would judge the behavior in terms of morality. As expected, our results indicate that the intention to deceive is not a necessary condition for lying. Participants rated indifferent lies to be lies and judged that no intention to deceive was involved in these cases. In addition, all bald-faced lies were evaluated as lies. However, participants widely ascribed an intention to deceive to bald-faced lies, which thus might not apply as counterexamples against the traditional definition of lying. Besides, lies are judged as morally wrong regardless of an intention to deceive. (shrink)

Lying is an everyday moral phenomenon about which philosophers have written a lot. Not only the moral status of lying has been intensively discussed but also what it means to lie in the first place. Perhaps the most important criterion for an adequate definition of lying is that it fits with people’s understanding and use of this concept. In this light, it comes as a surprise that researchers only recently started to empirically investigate the folk concept of lying. In this (...) paper, we describe three experimental studies which address the following questions: Does a statement need to be objectively false in order to constitute lying? Does lying necessarily include the intention to deceive? Can one lie by omitting relevant facts? (shrink)

Indifferent lies have been proposed as a counterexample to the claim that lying requires an intention to deceive. In indifferent lies, the speaker says something she believes to be false (in a trut...

In their paper published in 2017 in Philosophical Psychology, Ronja Rutschmann and Alex Wiegmann introduce a novel kind of lies, the indifferent lies. According to them, these lies are not intended to deceive simply because the liars do not care whether their audience is going to believe them or not. It seems as if indifferent lies avoid the objections raised against other kinds of lies supposedly not intended to deceive. I argue that this is not correct. Indifferent lies, (...) too, are either intended to deceive or are not lies at all, since they do not involve genuine assertions. (shrink)

The recent discovery and structure determination of a novel ubiquitin‐like dimerization domain in protein kinase D (PKD) has significant implications for its activation. PKD is a serine/threonine kinase activated by the lipid second messenger diacylglycerol (DAG). It is an essential and highly conserved protein that is implicated in plasma membrane directed trafficking processes from the trans‐Golgi network. However, many open questions surround its mechanism of activation, its localization, and its role in the biogenesis of cargo transport carriers. In reviewing this (...) field, the focus is primarily on the mechanisms that control the activation of PKD at precise locations in the cell. In light of the new structural findings, the understanding of the mechanisms underlying PKD activation is critically evaluated, with particular emphasis on the role of dimerization in PKD autophosphorylation, and the provenance and recognition of the DAG that activates PKD.

While art is omnipresent in human history, the neural mechanisms of how we perceive, value and differentiate art has only begun to be explored. Functional magnetic resonance imaging studies suggested that art acts as secondary reward, involving brain activity in the ventral striatum and prefrontal cortices similar to primary rewards such as food. However, potential similarities or unique characteristics of art-related neuroscience remain elusive, also because of a lack of adequate experimental tools: the available collections of art stimuli often lack (...) standard image definitions and normative ratings. Therefore, we here provide a large set of well-characterized, novel art images for use as visual stimuli in psychological and neuroimaging research. The stimuli were created using a deep learning algorithm that applied different styles of popular paintings on ordinary animal, plant and object images which were drawn from established visual stimuli databases. The novel stimuli represent mundane items with artistic properties with proposed reduced dimensionality and complexity compared to paintings. In total, 2,332 novel stimuli are available open access as “art.pics” database at https://osf.io/BTWNQ/ with standard image characteristics that are comparable to other common visual stimuli material in terms of size, variable color distribution, complexity, intensity and valence, measured by image software analysis and by ratings derived from a human experimental validation study [n = 1,296, age 30.2 ± 8.8 y.o.]. The experimental validation study further showed that the art.pics elicit a broad and significantly different variation in subjective value ratings as well as in recognizability, arousal and valence across different art styles and categories. Researchers are encouraged to study the perception, processing and valuation of art images based on the art.pics database which also enables real reward remuneration of the rated stimuli and a direct comparison to other rewards from e.g., food or money.Key Messages: We provide an open access, validated and large set of novel stimuli of standardized art images including normative rating data to be used for experimental research. Reward remuneration in experimental settings can be easily implemented for the art.pics by e.g., handing out the stimuli to the participants, as done in the presented validation task. Experimental validation showed that the art.pics’ images elicit a broad and significantly different variation in subjective value ratings across different art styles and categories, while size, color and complexity characteristics remained comparable to other visual stimuli databases.

Definition of the problem The eleventh version of the International Classification of Diseases (ICD-11), which became effective in 2022, has raised a number of issues associated with medical ethics. Arguments In this context the paper explores the normative view of grief as a disease. ICD-11 contains the new diagnosis of “prolonged grief disorder” with a definition that fails to aid its clear distinction from the normal course of grief. The article discusses the philosophical and ethical implications of this diagnosis and (...) explores the risks of medicalizing and pathologizing grief which may lead to an undermining of its value. Conclusions and further perspectives The paper’s specific focus is the particular case of parental grief. We show that pediatric palliative care counteracts many risk factors for difficult grief reactions and may therefore serve as a valuable instrument for their prevention. We propose in this context the concept of “advance bereavement planning” as a potentially beneficial extension of advance care planning and palliative care in general. (shrink)

Zusammenfassung: Die Covid-19-Pandemie und der politische Umgang mit ihr beeinflussen sämtliche Bereiche des gesellschaftlichen Lebens auf vielfältige Weise. Ziel dieses Artikels ist es, eine Güterabwägung am Beispiel schwerkranker Kinder und ihrer Familien als vulnerabler Gruppe durchzuführen, um politische Entscheidungen ethisch zu reflektieren. Dafür wird herausgearbeitet, was die Kinderpalliativmedizin im Vergleich zu anderen medizinischen Fachbereichen auszeichnet, und dargestellt, dass ihr Fokus auf der Linderung des „Total Pain“ nach Cicely Saunders liegt. Anhand einer Kasuistik wird ersichtlich, dass die Kinderpalliativmedizin aus diesem Grund (...) durch die vielfältigen Einflüsse der Pandemie auf die physische, psychische, soziale und spirituelle Dimension betreuter Familien vor besondere Herausforderungen gestellt wird. In diesem Zuge wird ebenfalls erläutert, dass Familien mit kinderpalliativmedizinischem Bedarf im Kontext der Covid-19-Pandemie als vulnerable Gruppe angesehen werden können und weshalb die Notwendigkeit einer ausführlichen Güterabwägung besteht. Im Rahmen einer anschließenden ethischen Diskussion wird eine derartige Güterabwägung unter der Einschränkung von Unsicherheit durchgeführt und auf die Problematik der politischen Situation als eines „tragischen Dilemmas“ eingegangen.

Well characterized databases used for experimental purposes with extensive meta-data are essential for conducting meaningful and comparable studies. The Food-pics_extended database is one example for a widely used food stimulus database. Indeed, meta-data on low level and high level image characteristics is broad, yet fiber ratings are not included, limiting its use in diet-related studies. Therefore, we developed fiber ratings per item, based on mean values of four non-expert raters. Ratings show good reliability and meaningful ranges per food type. The (...) newly provided fiber ratings enrich the already valuable database and extend it by an important nutrient value for human and planetary health. (shrink)

In this study, the affective explicit and implicit attitudes toward electric and gasoline cars are investigated. One hundred sixty-five participants completed an explicit and implicit affective rating task toward pictures of electric and gasoline cars, measurements of sustainability, future and past behaviors, and mindfulness. The results showed a positive emotional attitude for the electric cars compared with the gasoline cars only for the explicit rating but not for the implicit one. Furthermore, factors that correlated to the attitudes were investigated: explicit (...) ratings in car owners correlated with age, degree, sustainability in general, and the expressed intention to purchase an electric car in the future. Implicit attitudes in car owners correlated with the overall score of mindfulness and the dimension of “non-reactivity.” For the non-car owners, explicit attitudes correlated with the expressed intention to purchase an electric car in the future and the mindfulness dimension of “describing”. In this group, the implicit attitude correlated negatively with the mindfulness intention of acting with awareness. This indicates that several different factors should be considered in the development of promotion campaigns for the advantage of sustainable mobility behavior. (shrink)
