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…

Impact of Emotional Intelligence on Burnout among Spanish Teachers: A Mediation Study
2021
espanolLa utilidad de la inteligencia emocional y su efecto tranquilizador sobre el estres laboral de los profesores han ido cobrando importancia en este campo de investigacion. El objetivo de este estudio ha sido analizar la relacion entre las habilidades emocionales y el sindrome de burnout y si el equilibrio afectivo media esta asociacion. Se han utilizado modelos de ecuaciones estructurales con datos de autoinforme de 200 profesores cuya edad estaba comprendida entre los 22 y los 64 anos (M = 44.97, SD = 9.31, 73.50% mujeres). Se utilizo un diseno transversal para el estudio. Los resultados mostraron un efecto significativo directo e indirecto de la claridad y de la reparacion emocional…
Individual Differences Facing the COVID-19 Pandemic: The Role of Age, Gender, Personality, and Positive Psychology
2021
Research on individual differences in facing the COVID-19 pandemic seems to be crucial in order to design diverse and highly effective intervention strategies. This study uses a sample of 302 North American participants who were recruited through the crowdsourcing platform ProA; different profiles were established, profiling variables of interest in facing the COVID-19 outbreak. Socio-demographic and psychological (personality traits, gratitude, life purpose, and religiosity) variables were explored. These results are of interest if we want to deepen the study of individual differences at both a theoretical and applied level.
Relations between Parenting Stress, Attachment, and Life Satisfaction in Mothers of Adolescent Children
2016
Relacje przyczynowe pomiędzy stresem rodzicielskim, przywiązaniem i zadowoleniem z życia dotychczas poddawane analizie są traktowane wielokierunkowo w zależności od ich osadzenia w odmiennych ramach teoretycznych. Ponadto, relacje pomiędzy nimi zależą od wielu zmiennych, które mogą oddziaływać na analizowane relacje jako potencjalne czynniki zakłócające. W naszym badaniu podjęliśmy się analizy związku pomiędzy stresem rodzicielskim matek i ich zadowoleniem z życia zapośredniczonego poprzez jakość przywiązania, rozumianego, jako ogólna orientacja matki w bliskich związkach. Przywiązanie było przez nas traktowane jako rodzaj zasobów osobistych matek, który zgodnie z naszymi założeniami działa…
Guessing Meaning From Word Sounds of Unfamiliar Languages: A Cross-Cultural Sound Symbolism Study
2019
Sound symbolism refers to a non-arbitrary relationship between the sound of a word and its meaning. With the aim to better investigate this relationship by using natural languages, in the present cross-linguistic study 215 Italian and Polish participants were asked to listen to words pronounced in 4 unknown non-indo-European languages (Finnish, Japanese, Swahili, Tamil) and to try to guess the correct meaning of each word, by choosing among 3 alternatives visualized on a computer screen. The alternatives were presented in the mother tongue of participants. Three different word categories were presented: nouns, verbs and adjectives. A first overall analysis confirmed a semantic role of sound…
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…
HabitApp: New Play Technologies in Pediatric Cancer to Improve the Psychosocial State of Patients and Caregivers
2020
[EN] Childhood cancer involves long periods of hospitalization that trigger emotions such as fear or sadness. Previous research has studied the positive effects of technology games on improving the hospitalization experience, but most do not focus on caregivers and none allow interaction with the real time observation of a zoo. The present study evaluates the impact of HabitApp and assesses the short-term impact on the psychosocial state of patients and caregivers in order to improve the hospitalization experience. The participants in this study were 39 patients plus 39 caregivers. A quantitative analysis revealed a significant improvement in patient's and caregiver's psychosocial factors f…
Global Estimation of Biophysical Variables from Google Earth Engine Platform
2018
This paper proposes a processing chain for the derivation of global Leaf Area Index (LAI), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Fraction Vegetation Cover (FVC), and Canopy water content (CWC) maps from 15-years of MODIS data exploiting the capabilities of the Google Earth Engine (GEE) cloud platform. The retrieval chain is based on a hybrid method inverting the PROSAIL radiative transfer model (RTM) with Random forests (RF) regression. A major feature of this work is the implementation of a retrieval chain exploiting the GEE capabilities using global and climate data records (CDR) of both MODIS surface reflectance and LAI/FAPAR datasets allowing the global estim…
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
