Interpolation in 16-Valued Trilattice Logics

In a recent paper we have defined an analytic tableau calculus \({{\mathbf {\mathsf{{PL}}}}}_{\mathbf {16}}\) for a functionally complete extension of Shramko and Wansing’s logic based on the trilattice \({SIXTEEN}_3\). This calculus makes it possible to define syntactic entailment relations that capture central semantic relations of the logic—such as the relations Open image in new window , Open image in new window , and Open image in new window that each correspond to a lattice order in \({SIXTEEN}_3\); and Open image in new window , the intersection of Open image in new window and Open image in new window . It turns out that our method of characterising these semantic relations—as intersections of auxiliary relations that can be captured with the help of a single calculus—lends itself well to proving interpolation. All entailment relations just mentioned have the interpolation property, not only when they are defined with respect to a functionally complete language, but also in a range of cases where less expressive languages are considered. For example, we will show that Open image in new window , when restricted to \(\mathcal {L}_{tf}\), the language originally considered by Shramko and Wansing, enjoys interpolation. This answers a question that was recently posed by M. Takano.     

Ernest Gellner's Words and Things: A Case Study of Empirical Philosophy

This article considers how Ernest Gellner used sociology and anthropology to attack ordinary language philosophy in Words and Things. It argues that this attack can be seen as a part of the movement to make philosophy more empirical or “naturalized,” something that has not been generally noted. It also discusses what general lessons to draw from Words and Things regarding how empirical knowledge should be used in philosophy. Among other things, the article argues that one important lesson is that empirical philosophers should make more use of “soft” social sciences, such as sociology and anthropology, and not focus exclusively on “harder” disciplines, such as physics and experimental psychology. Another upshot of the discussion is that philosophers should draw on empirical knowledge not only when they solve problems but also when they formulate them.     

When immigrant groups “misbehave”: The influence of perceived deviant behavior on increased threat and discriminatory intentions and the moderating role of right‐wing authoritarianism

In two studies, we tested the relationship between non‐immigrant individuals' perceptions of deviant behavior carried out by Muslims and foreigners and discriminatory intentions towards these outgroups. Based on a longitudinal and a representative cross‐sectional sample, we showed that two different types of perceived deviant behavior (Study 1, Muslims' unwillingness to integrate; and Study 2, foreigners' hostility towards the non‐immigrant majority group) are related to increased intergroup threat, which in turn is related to increased intentions to show passive discrimination (i.e., avoidance) towards these outgroups. In line with theorizing about an increased sensitivity for threat in authoritarian individuals, the relationship between perceptions of deviant behavior and threat was especially strong among high authoritarian individuals. Theoretical and practical implications of our results are discussed.     

The impact of concurrent visual feedback on coding of on-line and pre-planned movement sequences

The purpose of this study was to determine the extent to which participants could effectively switch from on-line (OL) to pre-planned (PP) control (or vice versa) depending on previous practice conditions and whether concurrent visual feedback was available during transfer testing. The task was to reproduce a 2000 ms spatial–temporal pattern of a sequence of elbow flexions and extensions. Participants were randomly assigned to one of two practice conditions termed OL or PP. In the OL condition the criterion waveform and the cursor were provided during movement production while this information was withheld during movement production for the PP condition. A retention test and two effector transfer tests were administered to half of the participants in each acquisition conditions under OL conditions and the other half under PP conditions. The mirror effector transfer test required the same pattern of muscle activation and limb joint angles as required during acquisition. The non-mirror transfer test required movements to the same visual–spatial locations as experienced during acquisition. The results indicated that when visual information was available during the transfer tests performers could switch from PP to OL. When visual information was withdrawn, they shifted from the OL to the PP-control mode. This finding suggests that performers adopt a mode of control consistent with the feedback conditions provided during testing.     

Comparative analysis of the risk-handling procedures for gene technology applications in medical and plant science

In this paper we analyse how the risks associated with research on transgenic plants are regulated in Sweden. The paper outlines the way in which pilot projects in the plant sciences are overseen in Sweden, and discusses the international and national background to the current regulatory system. The historical, and hitherto unexplored, reasons for the evolution of current administrative and legislative procedures in plant science are of particular interest. Specifically, we discuss similarities and differences in the regulation of medicine and plant science, and we examine the tendency towards dichotomizing risk — focusing on social/ethical risks in medicine and biological risks in plant science. The context of this article is the Synpraxia research project, an inter-disciplinary program combining expertise in sciences and the humanities.     

Single-trial EEG-fMRI reveals the dynamics of cognitive function

Two major non-invasive techniques in cognitive neuroscience, electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), have complementary advantages with regard to their spatial and temporal resolution. Recent hardware and software developments have made it feasible to acquire EEG and fMRI data simultaneously. We emphasize the potential of simultaneous EEG and fMRI recordings to pursue new strategies in cognitive neuroimaging. Specifically, we propose that, by exploiting the combined spatiotemporal resolution of the methods, the integration of EEG and fMRI recordings on a single-trial level enables the rich temporal dynamics of information processing to be characterized within spatially well-defined neural networks.     

Spontaneous emotion regulation during evaluated speaking tasks: associations with negative affect, anxiety expression, memory, and physiological responding

In these studies, the correlates of spontaneously using expressive suppression and cognitive reappraisal during stressful speeches were examined. Spontaneous emotion regulation means that there were no instructions of how to regulate emotions during the speech. Instead, participants indicated after the speech to what extent they used self-motivated expressive suppression or reappraisal during the task. The results show that suppression is associated with less anxiety expression, greater physiological responding, and less memory for the speech while having no impact on negative affect. In contrast, reappraisal has no impact on physiology and memory while leading to less expression and affect. Taken together, spontaneous emotion regulation in active coping tasks has similar consequences as experimentally induced emotion regulation in passive tasks.
