Recent reasoning accounts suggest that people can process elementary logical principles intuitively. These controversial “logical intuitions” are believed to result from a learning process in which developing reasoners automatize their application. To verify this automatization hypothesis, we contrasted the reasoning performance of younger (7th grade) and older (12th grade) reasoners with a two-response paradigm. Participants initially responded with the first intuitive response that came to mind and subsequently were allowed to deliberate on classic “bias” problems (base-rate problems and syllogisms). Results (...) showed that in addition to showing less deliberate correction of an initial erroneous response, younger reasoners were specifically less likely to generate the correct response from the outset. The findings lend credence to the role of a developmental automatization process and indicate that developmental improvements in reasoning accuracy are at least partially driven by an improvement in the accuracy of our intuitions.

Enhancement - Behinderung - gutes Leben. Der Band verknupft diese drei Themen und entwickelt einen breiten Zugang zur Debatte um die biotechnologischen Moglichkeiten zur Verbesserung des menschlichen Korpers. Die Beitrage gehen von der Arbeitshypothese aus, dass die Erfahrungen von Menschen mit Behinderungen wichtig sind, um ethische Fragen, die sich bei Enhancement-Projekten stellen, konkreter - und so besser - zu verstehen. Eine zweite Hypothese ist, dass die Sprache der Rechte, Pflichten und Verbote nicht ausreicht, um zu erfassen, worum es im Kern (...) der Fragen zum Enhancement in ethischer Hinsicht geht. Stattdessen muss geklart werden, inwieweit mit einer moglichen Verbesserung auch eine Steigerung des menschlichen Wohls verbunden ist und welche Veranderungen im Kontext eines guten Lebens wunschenswert sind.".

This paper investigates the production and circulation of the illustrations in Fritz Kahn’s five-volume series The Life of Man, one of the most popular medical publications in the German interwar period. In 1912 Kahn (1888–1968), together with a staff of illustrators, began producing what would later become his best-selling series. Illustrations of this series (in particular, the poster The human factory/der Mensch als Industriepalast) were widespread throughout Germany during the Weimar Republic. With the rise of National Socialism, Kahn was forced (...) to emigrate in 1933. While his books were forbidden by the Nazi regime, their illustrations continued to play an important role in popular scientific discourse: they reappeared in the Nazi health-education programme and were adapted for Kahn’s publications in exile at the same time. This paper discusses how their production process and collective authorship made this complex and heterogeneous reception possible. (shrink)

Der Aufsatz zielt auf eine nähere Präzisierung der üblicherweise gegebenen Bestimmung, Leibniz sei „Kompatibilist“ gewesen. Willensfreiheit ist für Leibniz mit Gottes Vorherwissen und Vorherbestimmung sowie mit dem Prinzip des zureichenden Grundes kompatibel, keineswegs jedoch mit Indifferenz. Urn die Vereinbarkeit der Willensfreiheit mit vollständigen individuellen Begriffen zu zeigen, scheint der Rekurs auf Gegenstücke in anderen möglichen Welten unerläßlich. Es wird argumentiert, daß Willensfreiheit für Leibniz nicht mit der prinzipiellen Vorhersagbarkeit von Willensentscheidungen durch einen menschlichen Beobachter oder durch einen Laplaceschen Dämon kompatibel (...) ist.

The parameters governing our behavior are in constant flux, and capturing these dynamics in cognitive models remains a challenge. We demonstrate how a mapping between ACT‐R's model of declarative memory and the linear ballistic accumulator enables efficient estimation of memory parameters from data. The resulting estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals.

Improving human characteristics goes beyond compensating for an impairment. This book explores the rich and complex relationship between enhancement and impairment, showing that the study of disability offers new ways of thinking about the social and ethical implications of improving the human condition.
