Detachment and defeasibility in deontic logic

The purpose of the paper is to present a logical framework that allow to formalize a kind of prima facie duties, defeasible conditional duties, indefeasible conditional duties and actual (indefeasible) duties, as well as to show their logical interconnections.     

Spoonish spanerisms: A lexical bias effect in Spanish

Lexical bias is the tendency for phonological errors to form existing words at a rate above chance. This effect has been observed in experiments and corpus analyses in Germanic languages, but S. del Viso, J. M. Igoa, and J. E. García-Albea (1991) found no effect in a Spanish corpus study. Because lexical bias plays an important role in the debate on interactivity in language production, the authors reconsidered its absence in Spanish. A corpus analysis, which considered relatively many errors and which used a method of estimating chance rate that is relatively independent of total error number, and a speech-error elicitation experiment provided converging evidence for lexical bias in Spanish. The authors conclude that the processing mechanisms underlying this effect hold cross-linguistically.     

Creative thinking in adolescents with attention deficit hyperactivity disorder (ADHD).

A widened attentional focus, that is typically associated with ADHD, has been postulated to be accompanied by enhanced creative ability. However, creativity has been only limitedly examined in ADHD. Performance across several creativity measures were investigated in three groups: adolescents with ADHD, those with conduct disorder, and a healthy control sample. The ADHD group exhibited selective cognitive advantages and disadvantages by demonstrating an enhanced ability in overcoming the constraining influence of examples, but a reduced capacity to generate a functional invention during an imagery task. These findings are interpreted with reference to inhibitory control mechanisms and the contextual modulation of creative cognition.     

Anxiolytic-like activity of SB-205384 in the elevated plus-maze test in mice

Recent studies point to a major role for alpha2-containing GABA-A receptors in modulating anxiety. However, the possible implication of GABA-A receptors containing the alpha3 subunit on anxiety is less known. The aim of this study was to examine the effects of SB-205384 (0.5-4 mg/kg, i.p.), an alpha3 subunit positive modulator of GABA-A receptor, on anxiety tested in the elevated plus-maze in male mice, using classical and ethological parameters. Mice treated with SB-205384 showed an increase in the frequency of entries and the time spent in open arms, as well as a reduction in the time spent in closed arms, as compared with the control group. A notable increase of "head-dipping" unprotected and a reduction of "stretched-attend posture" protected was also evident. These findings indicate that SB-205384 exhibits an anxiolytic-like profile in the elevated plus-maze test, suggesting that GABA-A receptors which contain the alpha3 subunit might be involved in regulation of anxiety.     

Determinants of instrumental extinction in terrestrial toads (Bufo arenarum)

Previous research in a water-reinforced instrumental training situation with toads (Bufo arenarum) has shown that performance in both acquisition and extinction is poorer after partial, rather than continuous reinforcement training. In Experiment 1, the performance of a group receiving 24 trials on a 50% partial reinforcement schedule was poorer in acquisition and extinction than that of continuously reinforced groups matched for trials or reinforcements. However, partially reinforced toads extinguished at the same rapid rate as a continuously reinforced group that received training only on the days in which the partial toads received water reinforcement. In Experiment 2, extinction was faster after 10 reinforced acquisition trials than after 30 trials. This evidence suggests that the deleterious effects of partial reinforcement in toads can be explained by a combination of two factors, namely, the distribution of reinforced trials across days and the total number of reinforcements.     

A typology of religious attitudes among young people in Germany

Issues like faith and Church, religion and religiousness are not valued particularly highly among the young. At the same time a search for the meaning of life and an orientation in one’s own behaviour still seem to be significant and transcendent focal points are being sought to deal with these issues. This article questions the value that religion, faith and the Church have for young people on the basis of empirical data. Five types of religious orientation of young people are identified: a churchly Christian type, an autonomously Christian type, a conventionally religious type, an autonomously religious type and, finally, a non‐religious type. The empirical data are taken from a study of about 800 pupils in the Grade 11 (age 16–17 years) from grammar schools (Gymnasien) in Germany.     

The Unhappy Marriage of Care Ethics and Virtue Ethics

The proposal that care ethic(s) (CE) be subsumed under the framework of virtue ethic(s) (VE) is both promising and problematic for feminists. Although some attempts to construe care as a virtue are more commendable than others, they cannot duplicate a freestanding feminist CE. Sander‐Staudt recommends a model of theoretical collaboration between VE and CE that retains their comprehensiveness, allows CE to enhance VE as well as be enhanced by it, and leaves CE open to other collaborations.
