N. R. Hanson and von Uexküll: A Biosemiotic and Evolutionary Account of Theories

Journal for General Philosophy of Science - This paper proposes a biosemiotic conception of theories, as non-intentional organic theories, which is based on an analysis and comparison of...     

The Challenge of Being a Challenger: Social Dominance Orientation Shapes the Impact of “Challenger vs. Leader” Comparisons

The current research investigates when and how comparative advertising effectiveness is shaped by social dominance orientation (SDO), that is, the degree to which one desires to maintain the status quo in social hierarchies. We examine these issues with regard to “challenger vs. leader” comparisons that seek to change the relative standing of competitors in a product category by documenting the superiority of challenger brands over market leaders. Findings demonstrate that the resistance to change characterizing high (vs. low) SDO individuals makes them respond (1) less favorably to “challenger vs. leader” comparisons that seek to alter the existing category hierarchy and (2) more favorably to “leader vs. challenger” comparisons that preserve this status quo in the category hierarchy. The theoretical implications of these findings are discussed, as are avenues for future research.     

Internality attribution and intergroup relations

In two studies, subjects filled out a questionnaire requiring them to choose between internal and external explanations of desirable or undesirable events. They were also asked to fill out the same questionnaire from another person's point of view, either a member of the ingroup or a member of the outgroup. The first study used students as subjects and the events were about student life. The second study used employees for subjects and the events were about the working world. As predicted on the basis of internality norm theory, internal explanations were generally found to be chosen more often when the respondent or imagined respondent was said to be a worthy person. The internality scores were the highest for oneself and for the ingroup member, regardless of the desirability of the events; they were the lowest for the outgroup member. These internality attribution effects do not seem to stem from the well-known ingroup-favouring attributions (ultimate attribution error). Hence, the internality norm construct, irrespective of event desirability, provides a new pathway for exploring the evaluative effects of intergroup relations. © 1998 John Wiley & Sons, Ltd.

Cognitive templates for religious concepts: cross-cultural evidence for recall of counter-intuitive representations

Presents results of free-recall experiments conducted in France, Gabon and Nepal, to test predictions of a cognitive model of religious concepts. The world over, these concepts include violations of conceptual expectations at the level of domain knowledge (e.g., about 'animal' or 'artifact' or 'person') rather than at the basic level. In five studies we used narratives to test the hypothesis that domain-level violations are recalled better than other conceptual associations. These studies used material constructed in the same way as religious concepts, but not used in religions familiar to the subjects. Experiments 1 and 2 confirmed a distinctiveness effect for such material. Experiment 3 shows that recall also depends on the possibility to generate inferences from violations of domain expectations. Replications in Gabon (Exp. 4) and Nepal (Exp. 5) showed that recall for domain-level violations is better than for violations of basic-level expectations. Overall sensitivity to violations is similar in different cultures and produces similar recall effects, despite differences in commitment to religious belief, in the range of local religious concepts or in their mode of transmission. However, differences between Gabon and Nepal results suggest that familiarity with some types of domain-level violations may paradoxically make other types more salient. These results suggest that recall effects may account for the recurrent features found in religious concepts from different cultures.     

Consolidation of Memory for Odor–Reward Association: β-Adrenergic Receptor Involvement in the Late Phase

Experimentally naive rats can learn rapidly to discriminate among three odors to obtain food reinforcement. After three massed trials, they show almost errorless performance. This task has proved to be useful in studying time-dependent postacquisition intracellular processes necessary for long-term memory. The present experiments evaluated the temporal dynamics of the role of β-noradrenergic receptors in long-term consolidation. Rats were implanted with intracerebroventricular cannulae and trained in a single session to find reinforcement in a hole in a sponge impregnated with a particular odor. Injections of the β-receptor antagonist timolol were made at 5 min, 1, 2, or 5 hr after training. Memory and relearning ability were evaluated 48 hr later. Rats treated with timolol 2 hr after training showed a memory deficit at the retention test, but were able to relearn the task normally. Injections at the earlier or later time points were ineffective. The results reinforce previous observations with systemic injections that β-noradrenergic receptors are involved in the late phase of memory consolidation and suggest a critical time window during which they are necessary. The time window is compatible with the current view that long-term memory depends on late involvement of the cAMP cascade leading to new protein synthesis necessary for synaptic reorganization.     

The history and future of the office of research integrity: Scientific misconduct and beyond

This paper looks at the issues and controversies that led to creation of the Office of Research Integrity (ORI) and that dominated its agenda in the early years. The successes and failures of ORI are described and new problems identified. This paper then looks ahead to the future, considering what issues will dominate ORI’s agenda and affect the research institutions, individual scientists, and the scientific community in the next several years.     

Interpretation without hermeneutics: A plea against ecumenism

I have been much helped by Axel Bühler writings on hermeneutics (in particular by his unpublished Conference sull'ermeneutica) and would like to thank him and Donald Davidson for comments.
