The author argues that there is no such thing as a unique and general taxonomy of non-at-issue contents. Accordingly, we ought to shun large categories such as “conventional implicature”, “F-implicature”, “CI”, “Class B” or the like. As an alternative, we may, first, describe the “semantic profile” of linguistic devices as accurately as possible. Second, we may explicitly tailor our categories to particular theoretical purposes.

In vision research metacontrast masking is a widely used technique to reduce the visibility of a stimulus. Typically, studies attempt to reveal general principles that apply to a large majority of participants and tend to omit possible individual differences. The neural plasticity of the visual system, however, entails the potential capability for individual differences in the way observers perform perceptual tasks. We report a case of perceptual learning in a metacontrast masking task that leads to the enhancement of two types (...) of adult human observers despite identical learning conditions. In a priming task both types of observers exhibited the same priming effects, which were insensitive to learning. Findings suggest that visual processing of target stimuli in the metacontrast masking task is based on neural levels with sufficient plasticity to enable the development of two types of observers, which do not contribute to processing of target stimuli in the priming task.

Sensory augmentation challenges current societal norms and views of what is conceived as a “normal” human being. Beginning with self reflections of a bodyhacker, the author proposes an extended view onto the human or respectively cyborg body. Based on cognitive theories, it is argumented that we are already mental cyborgs. Our brains plastically restructure themselves in order to meet new requirements of the technological extended human.

Silicon Valley is both object of intense fascination and stark criticism. Academic observers have described it as a unique amalgamation of hippie culture, libertarian thinking, wild experimentation, but also scientific rigor, high-tech precision, and turbo-capitalism – a seemingly improbable, even paradoxical combination. Nevertheless, Silicon Valley continues to be an economic powerhouse and a global innovation hub. The current study explores its socio-cultural and ideological foundations through the lens of an insider perspective to find explanations for its stability and sustained success (...) in light of conflicting components. Based on 15 interviews with Silicon Valley experts from start-ups, tech giants, and academic institutions, the study identifies several paradoxes on the level of ideology and environment, structure(s), and actors. These can be grouped into a binary, oppositional view, indeed describing the Silicon Valley paradox. However, alternative explanations are given, including the conceptualization as a non-dualist phenomenon. (shrink)

In metacontrast masking target visibility is modulated by the time until a masking stimulus appears. The effect of this temporal delay differs across participants in such a way that individual human observers’ performance shows distinguishable types of masking functions which remain largely unchanged for months. Here we examined whether individual differences in masking functions depend on different response criteria in addition to differences in discrimination sensitivity. To this end we reanalyzed previously published data and conducted a new experiment for further (...) data analyses. Our analyses demonstrate that a distinction of masking functions based on the type of masking stimulus is superior to a distinction based on the target–mask congruency. Individually different masking functions are based on individual differences in discrimination sensitivities and in response criteria. Results suggest that individual differences in metacontrast masking result from individually different criterion contents. (shrink)

Definition of the problem: Even after the new German legislation about organ donors and transplantation (“information solution”), the question of criteria for distributing the organs is still not solved. The various alternatives to solve this problem face different social acceptance and economic efficiency.Arguments: Medical criteria (e.g. HLA compatibility) and non-medical criteria (e.g. willingness to pay of the patients) are valued on the basis of generally accepted objectives (e.g. equal access to health services or low costs). As an innovative form of (...) organ distribution systems the club solution is introduced. It allows the donor to realise preferences regarding use of the organs.Conclusion: Scoring systems may help to increase the transparency of organ allocation. From an economic point of view medical criteria have to be weighted more than non-medical criteria. (shrink)

A first-person account of some victims of the virus, the author puts faces and circumstances to the tragedy of the Covid-19 pandemic. Told from a chaplain’s point of view, these narratives will take the reader beyond the numbers and ask questions like: What is the cost of keeping families separated at the end of life, and, if patient/family centered care is so central to healthcare these days, why was it immediately discarded? Is potentially saving human lives worth the risk of (...) damaging them beyond repair? (shrink)

The problem of finding sufficient doxastic conditions for backward induction in games of perfect information is analyzed in a syntactic framework with subjunctive conditionals. This allows to describe the structure of the game by a logical formula and consequently to treat beliefs about this structure in the same way as beliefs about rationality. A backward induction and a non-Nash equilibrium result based on higher level belief in rationality and the structure of the game are derived.

What, exactly, is the difference between words such as ‘dead’ and ‘deceased’? In this paper, I argue that such differences in register, or style, ought to be construed as genuine differences in non-truth-conditional meaning. I also show that register cannot plausibly accounted for in terms of either presupposition or conventional implicature. Register is, rather, an instance of what I call pure use-conditional meaning. In the case of register, a difference in meaning does not correspond to a difference in the contents (...) speakers intend to convey. (shrink)

ABSTRACTDepression is marked by rigid thinking and the inability to generate different and more positive views on the self. The current study conceptualises this a perspective-taking deficit, which is defined as a deficit in the ability to overcome one’s egocentrism. Previous research has demonstrated that individuals with depression are impaired in Theory of Mind reasoning and empathy – two social cognitions that involve cognitive and affective perspective-taking. Here, it was investigated whether these deficits generalise to visuo-spatial perspective-taking. To test this, (...) a convenience sample completed a test-battery including measures of cognitive and visuo-spatial perspective-taking and closely matched cognitive and visuo-spatial control tasks. The results showed that individuals exhibiting high levels of depressive symptoms were specifically impaired on both perspective-taking tasks but performed equally well on the cont... (shrink)

This paper is partly exegetical, partly systematic. I argue that Frege's account of what he called “colouring” contains some important insights on how communication is related to mental states such as mental images or emotions. I also show that the Fregean perspective is supported by current research in psycholinguistics and that a full understanding of some linguistic phenomena that scholars have accounted for in terms of either semantics or pragmatics need involve psycholinguistic elements.

In this issue of Consciousness and Cognition, Bachmann comments on our study , which revealed two groups of observers with qualitative individual differences in metacontrast masking that are enhanced by perceptual learning. We are pleased that our study receives this attention and even more about Bachmann’s extremely positive comments. In this invited reply we argue that observers seem to be similar only at the beginning of the experiment but they have no choice as to which group to join. Findings strongly (...) recommend to look at the data of individual subjects. (shrink)

„Rechtsgefühl“ kann das individuelle Gerechtigkeitsempfinden, das Judiz der Richterin im Entscheidungsfindungsprozess, das emotionale Aufbäumen der unterlegenen Partei nach der Entscheidung, eine kollektive Rechtsüberzeugung bezeichnen. Verweise auf das „Rechtsgefühl“ werden oft genutzt, um Rechtssysteme oder einzelne Rechtsakte von innen oder von außen zu legitimieren oder zu delegitimieren. Als sozialer Kompass und normative Rechtfertigung versagt „Rechtsgefühl“ dagegen, wenn es mit zahlreichen gegenläufigen Rechtsgefühlen konkurriert. Dieser Frage nach dem Stellenwert divergierender Rechts- und Gerechtigkeitsempfindungen gehen die in diesem Band versammelten Beiträge aus praktischer, theoretischer (...) und historischer Perspektive nach. Mit Beiträgen von Prof. Dr. Gabriele Britz, Prof. Dr. Jeanne Gaakeer, Prof. Dr. Thorsten Keiser, Prof. Dr. Sylvia Kesper-Biermann, Prof. Dr. Frans-Willem Korsten, Prof. Dr. Greta Olson und Prof. Dr. Franz Reimer.

This essay compares decade-long commemorations between American and Japanese veterans of Pearl Harbor, and the ancient kabuki legend of “Treading the Tiger's Tail”, which also concerns enemies who come to appreciate their commonalities. The “danger zones” in the joint Pearl Harbor reunions had less to do with enemies still fighting an old war, than with each nation's internally unresolved tensions and with sensitivities across a broader, more complex constellation of postures toward war memory. Hawai'i played a significant role in providing (...) a more culturally porous milieu for the veterans to meet, away from the mainstream tensions in each of their respective nations. (shrink)

In this paper, we apply imprinting theory to examine how institutional transformation substantially influences perceptions of corruption that we argue to be incorporated to a varying extent in organizations founded in that period. For this purpose, we compare the effect of a sudden shock (dissolution of the Soviet Union) on the managers' present perceptions to that of a steady transition (EU accession). We consult the 5th round of the Business Environment and Enterprise Performance Survey from 2012 to 2014 analyzing 4715 (...) interviews with managers of organizations from twelve Central and Eastern European countries. Our results reveal striking differences in the present perception of corruption for organizations founded immediately before and immediately after these institutional transitions. The study's results contribute to the research on imprinting theory regarding the relationship between organizations and institutional conditions that constitutes a lasting effect on organizational structures. Thus, applying an institutional perspective that considers less stable periods for organizations yields a promising avenue in research on organizational behavior. (shrink)

Als Erkenntnistheorie der phänomenologischen Erkenntnis versteht sich die folgende Untersuchung als ein zentrales Stück der von Husserl geforderten Selbstkritik der phänomenologischen Erkenntnis. Ausgehend vom normalsprachlichen Wahrheitsbegriff und dessen Explikation soll die prinzipielle Möglichkeit wahrer phänomenologischer Beschreibungen durch Rückgang auf das Phänomen der Wahrheit ausgewiesen werden. Im Anschluss an Husserls Analysen der vorprädikativen Erfahrung wird die explizierende Betrachtung (in Abgrenzung zum prädikativen Urteil) als die eigentlich erkennende, nämlich die kategorialen Strukturen der Phänomene erfassende und offenlegende Leistung exponiert, die einerseits anschaulich begründete (...) prädikative Urteile allererst ermöglicht und andererseits diese bewahrheitet. Die vorprädikative Erfassung liegt dabei auch der kategorialen Anschauung als einer bereits prädikativen Leistung konstitutiv zugrunde. (shrink)

A syntactic formalism for the modeling of belief revision in perfect information games is presented that allows to define the rationality of a player's choice of moves relative to the beliefs he holds as his respective decision nodes have been reached. In this setting, true common belief in the structure of the game and rationality held before the start of the game does not imply that backward induction will be played. To derive backward induction, a “forward belief” condition is formulated (...) in terms of revised rather than initial beliefs. Alternative notions of rationality as well as the use of knowledge instead of belief are also studied within this framework. Footnotes1 I would like to thank Wlodek Rabinowicz and three anonymous referees for very helpful comments. (shrink)

Frege's mature writings apparently contain two different criteria of sense identity. While in "Über Sinn und Bedeutung" (1892) and in "Kurze Übersicht meiner logischen Lehren" (1906?) he seems to advocate a psychological criterion, his letter to Husserl of December 12, 1906 offers a thoroughly logical criterion of sense identity. It is argued that the latter proposal is not a "momentary aberration", but rather Frege's official criterion; his psychological criteria only serve as a way of illustrating questions of sense identity by (...) appealing to the thoughts of completely rational thinkers.

Mathematicians often consider Zermelo-Fraenkel Set Theory with Choice (ZFC) as the only foundation of Mathematics, and frequently don’t actually want to think much about foundations. We argue here that modern Type Theory, i.e. Homotopy Type Theory (HoTT), is a preferable and should be considered as an alternative.

Plastids and mitochondria arose through endosymbiotic acquisition of formerly free-living bacteria. During more than a billion years of subsequent concerted evolution, the three genomes of plant cells have undergone dramatic structural changes to optimize the expression of the compartmentalized genetic material and to fine-tune the communication between the nucleus and the organelles. The chimeric composition of many multiprotein complexes in plastids and mitochondria (one part of the subunits being nuclear encoded and another one being encoded in the organellar genome) provides (...) a paradigm for co-evolution at the cellular level. In this paper, we discuss the co-evolution of nuclear and organellar genomes in the context of environmental adaptation in species and populations. We highlight emerging genetic model systems and new experimental approaches that are particularly suitable to elucidate the molecular basis of co-adaptation processes and describe how nuclear-cytoplasmic co-evolution can cause genetic incompatibilities that contribute to the establishment of hybridization barriers, ultimately leading to the formation of new species.
