Frames, i.e., recursive attribute-value structures, are a general format for the decomposition of lexical concepts. Attributes assign unique values to objects and thus describe functional relations. Concepts can be classified into four groups: sortal, individual, relational and functional concepts. The classification is reflected by different grammatical roles of the corresponding nouns. The paper aims at a cognitively adequate decomposition, particularly, of sortal concepts by means of frames. Using typed feature structures, an explicit formalism for the characterization of cognitive frames is (...) developed. The frame model can be extended to account for typicality effects. Applying the paradigm of object-related neural synchronization, furthermore, a biologically motivated model for the cortical implementation of frames is developed. Cortically distributed synchronization patterns may be regarded as the fingerprints of concepts. (shrink)

In der Dissertation "Kausalität und Naturgesetze bei Hume und Kant" wird die These vertreten, dass sich in der Werken Kants vielfältige Antworten auf den Skeptizismus David Humes finden lassen. Kants Position zu Naturgesetzen und Kausalität wird insbesondere anhand seiner Theorien zu besonderen Naturgesetzen in der Kritik der reinen Vernunft, den Prolegomena, den Metaphysischen Anfangsgründen der Naturwissenschaft und in der Kritik der Urteilskraft untersucht. Geleitet wird die Untersuchung von der Frage, wie empirische Gesetze in Kants Philosophie gerechtfertigt werden. In diesem Zusammenhang (...) wird nicht nur gezeigt, wie Kants Transzendentalphilosophie ein Fundament für die Einzelwissenschaften bietet und diese legitimiert, sondern auch der epistemologische Aufbau von apriorischen zu empirischen Gesetzen und ihre Einordnung in Systeme.

Although religious belief is often claimed to help with physical ailments including pain, it is unclear what psychological and neural mechanisms underlie the influence of religious belief on pain. By analogy to other top-down processes of pain modulation we hypothesized that religious belief helps believers reinterpret the emotional significance of pain, leading to emotional detachment from it. Recent findings on emotion regulation support a role for the right ventrolateral prefrontal cortex, a region also important for driving top-down pain inhibitory circuits. (...) Using functional magnetic resonance imaging in practicing Catholics and avowed atheists and agnostics during painful stimulation, here we show the existence of a context-dependent form of analgesia that was triggered by the presentation of an image with a religious content but not by the presentation of a non-religious image. As confirmed by behavioral data, contemplation of the religious image eneabled the religious group to detach themselves from the experience of pain. Critically, this context-dependent modulation of pain specifically engaged the right VLPFC, whereas group-specific preferential liking of one of the pictures was associated with activation in the ventral midbrain. We suggest that religious belief might provide a framework that allows individuals to engage known pain-regulatory brain processes. (shrink)

How does microbiota research impact our understanding of biological individuality? We summarize the interdisciplinary summer school on "Microbiota, Symbiosis and Individuality: Conceptual and Philosophical Issues" (July 2019), which was supported by a European Research Council starting grant project "Immunity, DEvelopment, and the Microbiota" (IDEM). The summer school centered around interdisciplinary group work on four facets of microbiota research: holobionts, individuality, causation, and human health. The conceptual discussion of cutting-edge empirical research provided new insights into microbiota and highlights the value of (...) incorporating into meetings experts from other disciplines, such as philosophy and history of science.
