The P300 (P3) event-related brain potential (ERP) was elicited with auditory stimuli in order to compare three different tasks and to assess the effect of ageing from childhood to adolescence. Seventy-two subjects, ranging in age from 6 to 14 divided into three age groups, were selected for this study. In the active task, the subject was required to… (More)
In Conceptual Spaces (Gärdenfors 2000), dimensions and their relations provide a topological representation of a concept's constituents and their mode of combination. Consequently, as concepts are n-dimensional geometrical structures, conceptual change denotes the dynamic development of these structures. Following this basic assumption, we apply conceptual… (More)
Everyday life reasoning and argumentation is defeasible and uncertain. I present a probability logic framework to rationally reconstruct everyday life reasoning and argumentation. Coherence in the sense of de Finetti is used as the basic rationality norm. I discuss two basic classes of approaches to construct measures of argument strength. The first class… (More)
We report on the design of a blended-learning course in elementary symbolic logic. Challenges and solutions pertaining to the Blackboard e-learning environment (Blackboard Academic Suite Release 8.0) and a customized Gentzen-style proof checker are described. The purpose is to provide orientation for those in the planning stage of similar projects.
The Central Auditory Processing mechanism of binaural integration can be assessed through behav-ioural non-invasive procedures such as the Dichotic Digit Test. This procedure consists of simultaneous presentation of digits to the two ears in an unpredictable presentation in groups of one, two and three pairs of items. The Dichotic Digit Test is commonly… (More)
