A Complete, Exact and Efficient Implementation for Computing the Edge-Adjacency Graph of an Arrangement of Quadrics
2011
International audience; We present a complete, exact and efficient implementation to compute the edge-adjacency graph of an arrangement of quadrics, i.e. surfaces of algebraic degree 2. This is a major step towards the computation of the full 3D arrangement. We enhanced an implementation for an exact parameterization of the intersection curves of two quadrics, such that we can compute the exact parameter value for intersection points and from that the edge-adjacency graph of the arrangement. Our implementation is complete in the sense that it can handle all kinds of inputs including all degenerate ones, i.e. singularities or tangential intersection points. It is exact in that it always comp…
Cough is dangerous : neural correlates of implicit body symptoms associations
2016
The negative interpretation of body sensations (e.g., as sign of a severe illness) is a crucial cognitive process in pathological health anxiety (HA). However, little is known about the nature and the degree of automaticity of this interpretation bias. We applied an implicit association test (IAT) in 20 subjects during functional magnetic resonance imaging (fMRI) to investigate behavioral and neural correlates of implicit attitudes towards symptom words. On the behavioral level, body symptom words elicited strong negative implicit association effects, as indexed by slowed reaction times when symptom words were paired with the attribute harmless (incongruent condition) relative to a control …
Processus attentionnels et apprentissage moteur
2012
International audience; Le but de cet article est de synthétiser les travaux portant sur les effets de l’attention volontaire sur l’apprentissage d’une habileté motrice. Les premiers modèles d’apprentissage considèrent que l’apprenant franchit plusieurs étapes au cours desquelles la sollicitation des processus attentionnels diminue (Fitts & Posner, 1967). Ainsi, la réalisation d’un mouvement nécessiterait d’engager de l’attention en début d’apprentissage alors qu’elle serait automatique en fin d’apprentissage. Cet article propose de vérifier cette affirmation au regard des recherches récentes qui révèlent que l’apprenant débutant module volontairement son attention a fin d’optimiser la réal…
Profesorado : revista de curriculum y formación del profesorado
2018
El propósito del artículo es revisar los resultados de investigaciones relativas al concepto de las teorías implícitas del profesorado en la Formación Profesional. Se parte del marco teórico establecido por Marrero (1988) contextualizado en la escolaridad obligatoria. El supuesto inicial que guía el análisis sugiere que el requerimiento de adaptación al mercado de trabajo que se atribuye a esta formación aproximaría al profesorado a la teoría técnica, en la que prima la definición de objetivos y la concreción de instrumentos evaluativos. El procedimiento metodológico parte de una revisión bibliométrica que ha permitido el análisis de cinco investigaciones sobre teorías implícitas dentro del…
Learning from Implicit Learning Literature: Comment on Shea, Wulf, Whitacre, and Park (2001)
2003
International audience; In their analysis of complex motor skill learning, Shea, Wulf, Whitacre, and Park (2001) have overlooked one of the most robust conclusions of the experimental studies on implicit learning conducted during the last decade--namely that participants usually learn things that are different from those that the experimenter expected them to learn. We show that the available literature on implicit learning strongly suggests that the improved performance in Shea et al.'s Experiments 1 and 2 (and similar earlier experiments, e.g., Wulf & Schmidt, 1997) was due to the exploitation of regularities in the target pattern different from those on which the postexperimental intervi…
Obraz "Tragedii Górnośląskiej" we współczesnych reportażach
2017
Po 1989 roku rozpoczął się w Polsce proces włączania w pamięć publiczną wydarzeń określanych mianem „Tragedii Górnośląskiej”, funkcjonujących wcześniej głównie w rodzinnych i lokalnych narracjach (służba Ślązaków w Wehrmachcie, wejście Armii Czerwonej na Śląsk, powojenne deportacje Ślązaków do ZSRR, obozy pracy dla przewidzianych do wysiedlenia do Niemiec mieszkańców Śląska). Ważną rolę w ujawnianiu tych tragicznych wydarzeń odgrywają dziennikarze i publicyści, autorzy reportaży historycznych, którzy docierają do świadków minionych wydarzeń i starają się wyjaśnić ukrywane do tej pory fakty. Autorka analizuje reportaże literackie, radiowe i telewizyjne podejmujące problematykę represji i zbr…
Sentence-Level Effects of Literary Genre: Behavioral and Electrophysiological Evidence
2017
The current study used event-related brain potentials (ERPs) and behavioral measures to examine effects of genre awareness on sentence processing and evaluation. We hypothesized that genre awareness modulates effects of genre-typical manipulations. We manipulated instructions between participants, either specifying a genre (poetry) or not (neutral). Sentences contained genre-typical variations of semantic congruency (congruent/incongruent) and morpho-phonological features (archaic/contemporary inflections). Offline ratings of meaningfulness (n=64/group) showed higher average ratings for semantically incongruent sentences in the poetry vs. neutral condition. ERPs during sentence reading (n=2…
Participation in Social Media: Studying Explicit and Implicit Forms of Participation in Communicative Social Networks
2016
The diverse forms of participation in social media raise many methodological and ethical issues that should be acknowledged in research. In this paper, participation in social media is studied by utilising the framework of explicit and implicit participation. The focus is on the communicative and communal aspects of social media. The aim of the paper is to promote the reconsideration of what constitutes participation when online users create connections rather than content. The underlying argument is that research on social media and the development of methods should concentrate more on implicit forms of participation.
The implications of teachers’ implicit theories for moral education: A case study from Finland
2017
Implicit theories concerning the malleability of human qualities are known to have a powerful impact on motivation and learning, but their role in moral education is an under-researched topic. In this qualitative case study, we examined the impact of implicit theories on four Finnish teachers’ practices of teaching morally and in teaching morality. The data include preliminary and stimulated recall interviews (STR) as well as classroom observations. Our results demonstrate the multiple ways in which teachers’ implicit beliefs are communicated to students and influence teacher’s interpretations and endeavors to educate the ethical capabilities of students. The study provides evidence for the…
Apprendimento, memoria, oblio
2012
Le teorie sulla memoria tengono conto sia della struttura della memoria che dei processi operanti al suo interno. Con il termine struttura ci si riferisce al modo in cui è organizzata la memoria, mentre con il termine processi si fa riferimento alle attività che si verificano all'interno della memoria. Apprendimento e memoria implicano una serie di stadi distinti. Il primo stadio noto come codifica, si riferisce a tutti quei fenomeni che hanno luogo durante la presentazione dell'informazione da ricordare. Il secondo stadio riguarda l'immagazzinamento delle informazioni come conseguenza del processo di codifica. Il terzo e ultimo stadio è il recupero delle informazioni immagazzinate.
