Analyse du partage d'informations contextuelles dans deux formes d'interaction sportives : coopérative et concurrentielle

2009

RESUME Plusieurs etudes ont souligne l’importance du partage d’informations contextuelles lors de tâches cooperatives. S’inspirant de la notion de contexte partage, notre etude visait a preciser le partage d’informations contextuelles dans deux formes d’interaction en tennis de table : une cooperative et une concurrentielle. Afin de reconstruire le partage d’informations contextuelles du point de vue des acteurs, cette etude a ete menee en reference au cadre theorique et methodologique du cours d’action (Theureau, 1992). Elle a permis : a) d’identifier trois formes typiques de partage des informations contextuelles ; et b) de preciser les processus regulant le partage de ces informations et…

Cognition collective : Partage de préoccupations entre les joueurs d'une équipe de basketball au cours d'un match

2011

Resume Notre etude s’est attachee a analyser la construction de l’activite collective en s’interessant au partage des preoccupations entre les partenaires d’une equipe lors d’un match de basket-ball. Elle a ete menee en reference au cadre theorique et methodologique du cours d’action (Theureau, 2006). Elle a caracterise la nature des preoccupations individuelles des joueurs et les formes d’agencement de ces preoccupations au sein de l’equipe au cours du temps. Les resultats ont mis en evidence deux dynamiques d’apparition des moments de convergence des preoccupations en relation avec la nature de ce qui est partage par les joueurs. Sont discutees la relation entre preoccupations partagees e…

Le mérite contre la justice

2019

International audience; Le mérite a la cote. Avec lui, l'idée que chacun est responsable de ce qui lui arrive, de ses succès comme de ses échecs, et l'espérance qu'en récompensant talents et efforts, on produira une société juste et efficace.La mise en exergue constante du mérite, sans tenir compte des inégalités (sociales, de genre, d'origine, etc.), est pourtant tout sauf anodine. Elle engendre de nombreux effets pervers : à l'école, où l'idéal de la formation de tous s'efface devant la sélection des plus "méritants" ; dans le monde du travail, quand se caler sur la réussite scolaire et le diplôme amène à négliger bien d'autres talents et à créer une concurrence délétère.Sans ôter tout mé…

Preliminary evaluation of an analog procedure to assess acceptability of intimate partner violence against women: The Partner Violence Acceptability …

2015

Acceptability of partner violence against women is a risk factor linked to its perpetration, and to public, professionals’ and victims’ responses to this behavior. Research on the acceptability of violence in intimate partner relationships is, however, limited by reliance solely on self-reports that often provide distorted or socially desirable accounts that may misrepresent respondents’ true attitudes. This study presents data on the development and initial validation of a new analog task assessing respondents’ acceptability of physical violence toward women in intimate relationships: the Partner Violence Acceptability Movie task (PVAM). This new analog task is intended to provide a more i…

Performance analysis in sport: Contributions from a joint analysis of athletes’ experience and biomechanical indicators

2011

The purpose of this study was to test the usefulness of combining two types of analysis to investigate sports performance with the aim of optimizing it. These two types of analysis correspond to two levels of athletes’ activity: (a) their experiences during performance and (b) the biomechanical characteristics of their movements. Rowing served as an illustration, and the activity of one female crew member was studied during a race. Three types of data were collected: (a) audiovisual data recorded during the race; (b) verbalization data obtained in interviews conducted afterward; and (c) biomechanical data. The courses of experience of the two rowers during the race were reconstructed on the…

Supporting Identity Development in Talented Youth Athletes: Insights from Existential and Cultural Psychological Approaches

2020

The purpose of this article is to present existential and cultural psychology approaches to understanding athlete identity, and offer strategies for the development of well-rounded, reflexive and s...

In this review, state-of-the-art evidence on the relationship between cannabis use, traffic crash risks, and driving safety were analyzed. Systematic reviews, meta-analyses, and other relevant papers published within the last decade were systematically searched and synthesized. Findings show that meta-analyses and culpability studies consistently indicate a slightly but significantly increased risk of crashes after acute cannabis use. These risks vary across included study type, crash severity, and method of substance application and measurement. Some studies show a significant correlation between high THC blood concentrations and car crash risk. Most studies do not support this relationshi…

A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness

2018

The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…

Analyzing the metrics of the perceptual space in a new multistage physiological colour vision model

2009

In this work, the metric of a new multistage colour vision model, ATTD05, is assessed and a new colour difference formula is suggested. Firstly, the uniformity of the ATTD05 colour space was compared with that of CIECAM02 for some Munsell samples, because if the model yields a uniform perceptual space, we will be able to implement a colour difference formula as a Euclidian distance between two points. Secondly, we developed a new space based on the perceptual descriptors of the model: brightness, hue, colourfulness, and saturation. After that, we calculated the free parameters of the space that better fit the measured and experimental data of two datasets (small-magnitude and large-magnitud…

Evaluating the user experience of omnidirectional VR walking simulators

2020

Abstract Omnidirectional treadmills (ODTs) have been traditionally proposed as a promising solution for users’ navigation in large-scale virtual environments. These mechanical devices enable users to perform locomotive motion with 360-deg freedom, while keeping their position fixed in the physical world. However, most locomotion approaches based on omnidirectional treadmills have presented either high acquisition or maintenance costs, being the capabilities of the general public, or a limited reliability. In this paper, we present a comparative usability and acceptance study with real users evaluating the two most common approaches for the development of this type of Virtual Reality (VR) wa…
