Avoidance learning by Guinea pigs

Albino guinea pigs were trained in shuttle-boxes. Superior performances were achieved with longer CS-US (15 sec. against 5 sec.) and intertrial intervals (90 sec. against 30 sec.). There were no performance increments within sessions, but improvements in performance occurred between sessions. Consolidation mechanisms probably play an important part in avoidance learning by guinea pigs.     

The initial capitalization superiority effect in German: evidence for a perceptual frequency variant of the orthographic cue hypothesis of visual word recognition

A perceptual frequency variant of the orthographic cue (OC) hypothesis (Peressotti, Cubelli, & Job, 2003) was tested in two perceptual identification experiments using the variable viewing position technique: German nouns and non-nouns that are most frequently perceived with or without initial letter capitalization, respectively, were tachistoscopically presented in upper-case, lower-case, or with initial capitalization. The results indicated that words were best recognized in the form they are most frequently perceived in, which suggests that during reading acquisition abstract as well as case- and item-specific OCs may be learned and used for recognition.     

The mental representation of numerical fractions: real or integer?

Numerical fractions are commonly used to express ratios and proportions (i.e., real numbers), but little is known about how they are mentally represented and processed by skilled adults. Four experiments employed comparison tasks to investigate the distance effect and the effect of the spatial numerical association of response codes (SNARC) for fractions. Results showed that fractions were processed componentially and that the real numerical value of the fraction was not accessed, indicating that processing the fraction's magnitude is not automatic. In contrast, responses were influenced by the numerical magnitude of the components and reflected the simple comparison between numerators, denominators, and reference, depending on the strategy adopted. Strategies were used even by highly skilled participants and were flexibly adapted to the specific experimental context. In line with results on the whole number bias in children, these findings suggest that the understanding of fractions is rooted in the ability to represent discrete numerosities (i.e., integers) rather than real numbers and that the well-known difficulties of children in mastering fractions are circumvented by skilled adults through a flexible use of strategies based on the integer components.     

Tragic Recognition: Revisiting Hegel’s Conception of Ethical Life

This paper interprets Hegel’s engagement with tragedy and especially tragic action as an interpretive model for understanding ethical life in complex societies in which independent value spheres collide. Tragic recognition, in contrast to the kind of recognition introduced in the master and slave dialectic, is not based on desire, but arises from the suffering deriving from clashing value spheres. As a coming to terms with one’s finitude, tragic recognition presents an important corrective to the account of mutual recognition that has been the reference point of contemporary interpretations of Hegel’s social and political philosophy. The paper concludes by pointing to some of the limits of tragedy as a universal interpretive framework for modern societies.     

Toward a Genealogy of Culture

Using psychoanalytic theory, this paper attempts to trace the natural history of the phenomenon designated as Culture. It postulates that psychoanalysis, a product of the Hegelian philosophical revolution, is still one of the best instruments to understand Culture. It traces the origins of culture as postulated by Freud and the pioneer anthropologists and its course from early and evolved religion through humanism, science, and finally postmodernism. It emphasizes the dialectical concepts in psychoanalysis and reviews summarily those psychoanalysts that, according to the author, have had a major impact on the study of culture: Freud, Horney, and Lacan.
