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)
the true state of the world). Sharing perspectives, then, improves information, which in turn might avoid or mitigate belief polarization—especially in groups that value conformity to neighboring members higher than " information obtained from the world. " Based on computer simulation, such groups are shown to de-polarize, provided their learning dynamic… (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)
Cross-linguistic influence (CLI) has been claimed to occur under the conditions of structural overlap, interfacing, syntactic complexity and language dominance. This study tested adjective placement in the Italian of 19 adult German–Italian simultaneous bilinguals, comparing naturalistic and experimental data. The results show no CLI from German, although… (More)
Recent work on conditional reasoning argues that denying the antecedent [DA] and affirming the consequent [AC] are defeasible but cogent patterns of argument, either because they are effective, rational, albeit heuristic applications of Bayesian probability, or because they are licensed by the principle of total evidence. Against this, we show that on any… (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.
