    The article analyzes the procedures of multitasking in reference to the literature on the working memory and the dual-task.With the present contribution the usefullness of surveying is supported on the procedures of multitasking like methodological strategy for the idealization, planning and realization of learning environment qualitatively effective within formative and didactic sciences

    The cognitive contribution of spatial representation to arithmetical skills

    Full text link
    The aim of the present paper is to show that, contrary to the main current approach to numerical cognition, the link between space and numbers cannot be reduced to the concept of a mental number line (MLN). A distinction between low-level numerical skills, that involve MLN processing, and higher level arithmetical skills, which are related to algorithmic processing, is needed in order to understand the different contribution given by visuo-spatial skills. I suggest that cognitive skills related to symbolic manipulation should be analyzed on their own in order to better understand the importance of spatial representation for arithmetical processing and, to this purpose, I propose a model of algorithmic skills that could be useful to study some typical features of symbolic manipulation, such as the influence of spatial schemes and the role for external resources in working memory offloading

    The mirror-neurons system: data and models

    No full text
    In this chapter we discuss the mirror-neurons system, a cortical network of areas that enables individuals to understand the meaning of actions performed by others through the activation of internal representations, which motorically code for the observed actions. We review evidence indicating that this capability does not depend on the amount of visual stimulation relative to the observed action, or on the sensory modality specifically addressed (visual, acoustical). Any sensorial cue that can evoke the "idea" of a meaningful action activates the vocabulary of motor representations stored in the ventral premotor cortex and, in humans, especially in Broca's area. This is true also for phonoarticulatory actions, which determine speech production. We present also a model of the mirror-neurons system and its partial implementation in a set of two experiments. The results, according to our model, show that motor information plays a significant role in the interpretation of actions and that a mirror-like representation can be developed autonomously as a result of the interaction between the individual and the environment

    Metaphors and Emotions as Framing Strategies in Argumentation

    No full text
    The paper focuses on the role of both emotional and metaphorical processes in reasoning. The aim of the paper is to present an extension of the argumentative theory of reasoning proposed by Mercier and Sperber (2011). In order to advance an integrated model of the roles of metaphors and emotions in argumentation, the paper argues that it is possible to ascribe not only a negative role to emotions and metaphors, but also a positive one. Far from being just a source of fallacies in reasoning, indeed, both emotions and metaphors – considered as framing and reframing strategies – can play a constructive role in argumentation, by enhancing their creative power

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
