The perceptual-cognitive ability to track multiple moving objects and its contribution to team sports performance has traditionally been studied in the laboratory under non-sports specific conditions. It is thus questionable whether the measured visual tracking performance and the underlying gaze activity reflected the actual ability of team sports players to track teammates and opponents on a real field. Using a Virtual Reality-based visual tracking task, the ability of participants to track multiple moving virtual players as they would do on a (...) soccer field was observed to pursue two objectives. See the influence of different scenario types on the visual tracking performance of soccer compared to non-soccer players. Observe the influence of spatial features of the simulated situations on gaze activity between soccer players and non-soccer players. The linear mixed model regression revealed a significant main effect of the group but no interaction effect between group and the type of trajectories, suggesting that the visual tracking ability of soccer players did not benefit from their specific knowledge when they faced scenarios with real game trajectories. Virtual players’ spatial dispersion and crowding affected the participants’ gaze activity and their visual tracking performance. Furthermore, the gaze activity of soccer players differed in some aspects from the gaze activity of non-soccer players. Assumptions are formulated as to the implication of these results in the difference in visual tracking performance between soccer players and non-soccer players. Overall, using soccer-specific trajectories might not be enough to replicate the representativeness of the field conditions in the study of visual tracking performance. Multitasking constraints should be considered along with motor-cognitive dual-tasks in future research to develop the representativeness of visual exploration conditions. (shrink)

It has been reported that behavior of experts and novices in various sporting tasks is impervious to the introduction of blur. However, studies have used diverse methods of blurring the visual stimulus, and tasks that did not always preserve the normal perception-action coupling. In the current study, we developed a novel experimental protocol to examine the effect of different levels of Gaussian blur on interception performance and eye gaze data using an immersive VR task. Importantly, this provided a realistic simulation (...) of a real-world boxing scenario in which expert combat athletes experienced a first-person, adaptive viewpoint of the visual environment, which could be blurred according to their gaze location. We found that participants exhibited similar interception performance in the presence of central blur or peripheral blur compared to a control condition with no blur. However, interception performance was significantly better with a central blur compared to peripheral blur. Eye gaze data indicated that although participants fixated at similar areas of interest irrespective of the presence of blur, fixation duration was significantly longer with a strong level of blur in the peripheral viewing condition than all levels of central blur and the control condition. These findings can be explained by relocating attention to different areas of the environment, which thereby influenced the perception of salient information. Participants also performed better on the first punch of a sequence preceded by a foot feint compared to arm feint or no feint. Still, irrespective of feint type, performance was significantly better on the second and third punch compared to the first punch. These findings are consistent with participants using additional information from the opponent's body movements and situational probabilities to increase performance as the sequence of punches developed. Overall, these are the first evidence for the use of VR as a means to examine gaze-contingent manipulations of the environment, and hence highlight the potential for facilitating learning and transfer to a real sporting situations.

Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain (...) activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.

The concept of the self and its relation to moral action is complex and subject to varying interpretations, not only between different academic disciplines but also across time and space. This paper presents empirical evidence from a cross-cultural study on the Buddhist and Confucian notions of self in SMEs in Vietnam and Taiwan. The study employs Hwang’s Mandala Model of the Self, and its extension into Shiah’s non-self-model, to interpret how these two Eastern philosophical representations of the self, the Confucian (...) relational self and Buddhist non-self, can lead to moral action. By demonstrating the strengths of the model, emphasizing how social and cultural influences constrain the individual self and promote the social person leading to moral action, the paper extends understanding of the self with empirical evidence of the mechanisms involved in organizational contexts.

This multidisciplinary volume explores the relationship between human rights and the subject. Each chapter considers how human rights norms and practices affect the way we relate to ourselves, to other people, and to the non-human world, drawing on the best work on human rights in political theory, cultural studies, history, law, anthropology, literary studies, and philosophy.

A commonly held view is that giving to the poor is superogatory i.e., that while it is a good thing to do, it is not morally wrong for us not to do so. This essay sets out to show that for the affluent in the world giving to the poor is not superogatory but is rather a moral obligation. The paper critiques Singer's famous argument in ‘Famine, Affluence and Morality’ and finds that although the argument is a cogent and powerful (...) one, Singer, when trying to apply the argument to how we should act, somewhat skews the argument's real implications. Furthermore, it is argued that a cosmopolitan concern for the global poor is the morally correct response to have, and the author defends this view by examining the proper effect that aspects like geographical distance, nationality, reciprocity, and the nature of the global economic system should have on our moral considerations. In conclusion, it is argued that since the way that each person utilises his/her resources is a reflection of what he/she values, then for many of us in positions of affluence, in order to be moral, much more should be done in order to help those experiencing dire, life-threatening poverty across the globe.1.

"Le Proslogion de Saint Anselme de Cantorbéry - l'œuvre la plus célèbre d'un des premiers et des plus grands philosophes du moyen âge - a joué dans l'histoire de la philosophie médiévale et moderne un rôle de tout premier plan. Il contient, en effet, ce fameux argument, dit..." ontologique ", qui - fortune à nulle autre pareille - sema la division et la discorde parmi les philosophes et les théologien".

Nombre de travaux ont fait ressortir les divergences entre Heidegger et Deleuze. Comment, à présent, faire converger leurs philosophies? Cette question nous occupe dans ce qui suit. Il s’agit d’abord de montrer que les pensées heideggérienne et deleuzienne se recoupent par leur volonté de mettre à bas les acceptions classiques du possible. Nous faisons voir, dans un second temps, que Heidegger et Deleuze se rejoignent aussi par leurs manières respectives de repenser le problème du possible. En troisième lieu, plongeant dans (...) les enjeux pratiques, nous nous demandons si le projet deleuzien n’est pas susceptible de venir compléter la philosophie heideggérienne. Notre objectif ne sera donc pas d’effacer de manière obtuse la distance entre Heidegger et Deleuze; il consistera, bien plutôt, à atténuer l’important écart qu’on voit d’ordinaire entre eux et à faire signe vers une certaine complémentarité, encore inaperçue jusqu’ici.

Cybernétique et psychanalyse, deux mots qui formeraient presque un oxymore. Pourtant cet ouvrage propose de repenser les liens entre la psychanalyse et l'informatique. Il révèle que les apports de la psychanalyse à l'épistémologie et l'histoire de l'informatique sont restés enfouis depuis près de soixante ans, alors même qu'elle fut une des premières disciplines à conceptualiser l'informatique, qui ne portait pas encore ce nom. Il s'agit alors à la fois de montrer l'apport pour la psychanalyse des recherches de l'informatique naissante, et (...) la particularité de l'approche psychanalytique de l'informatique, plus particulièrement chez Jacques Lacan. Cet ouvrage propose des outils et des concepts au lecteur pour prendre des distances par rapport à la trop simple opposition entre les sciences cognitives, voire les neurosciences, qui seraient la psychologie à l'ère du numérique, et la psychanalyse contemporaine.

O texto indaga acerca do núcleo das confrontações do pensamento contemporâneo, para mostrar qual é o lugar que corresponde, nesse contexto, à Levinas. Neste sentido, mostraremos, em primeiro lugar, o motivo principal pelo qual, tem-se produzido, nos últimos anos, uma revalorização do pensamento de Levinas, a saber, a virada ética contemporânea; em segundo lugar, ilustraremos uma das noções básicas da proposta filosófica levinasiana, que se encontra em íntima relação com os problemas que o pensamento contemporâneo tem desenvolvido: racionalidade ética como (...) abertura à diferença não indiferente – alteridade.

Normal 0 21 false false false MicrosoftInternetExplorer4 O presente artigo analisa a passagem da hermenêutica metodológica à experiência hermenêutica como crítica e fundamento do saber filosófico. Inicialmente, apresenta a crítica da hermenêutica à absolutizaçáo da lógica matemática como estrutura da pesquisa e produçáo de sentido na filosofia. A lógica matemática sedimenta a dinâmica da vida do homem por náo estar aberta às contingências da existência, porém a vida do homem náo se compreende sob a forma da lógica matemática. Posteriormente, demonstra (...) que compreender a dinâmica da vida do sujeito pressupõe uma hermenêutica filosófica, que interprete o verdadeiro sentido do humano. Essa compreensáo hermenêutico-filosófica se estabelece mediante uma inter-relaçáo entre o sujeito e o algo a ser interpretado. Por fim, defende que a condiçáo de possibilidade dessa inter-relaçáo é a experiência hermenêutica, o que implica uma abertura ao que esse algo tem a dizer ao sujeito, tornando-se, assim, o ponto de partida da compreensáo e fundamentaçáo do saber crítico-reflexivo.

The analysis of the circumstances in which Alexander Luria came to send letters to Kurt Goldstein sheds some light on the historical context of their existence. The documents show how strongly Luria and some of his colleagues were interested in Goldstein’s works in the early 1930s. These documents dating from the post Second World War years also testify to the beginning of the more than purely professional relationship between the two recognized neurologists (or neuropsychologists).

Alexandre Kabera L’Ubuntu est un concept issu des cultures africaines qui signifie « humanité » ou « bonté » en référence à la solidarité et à la fraternité. Il met l’accent sur l’importance de la communauté dans la vie des individus et sur la nécessité de prendre en compte les besoins des autres dans nos propres décisions et actions. Dans le récit de la guérison du paralytique en Marc 2,1-12, on peut voir comment les quatre porteurs et la foule (...) montrent de l’Ubuntu en aidant le paralytique à accéder à Jésus pour recevoir son pardon et sa guérison. Jésus lui-même montre de l’Ubuntu en pardonnant au paralytique et en le guérissant, mettant ainsi ses besoins avant les règles et les préjugés de la société. L’application du concept d’Ubuntu en exégèse peut donc offrir une perspective non occidentale sur le texte biblique en mettant en lumière les valeurs de communauté et de compassion présentes dans le récit.

Using a nationwide survey of provincial institutional quality and a sample of private manufacturing small and medium scale enterprises, this paper contributes to the literature by considering for the first time the effects of corruption on the financial performance of Vietnamese private SMEs. Interestingly, contrary to previous findings, we find that corruption when measured by a dummy variable, does not affect firms’ financial performance after controlling for heterogeneity, simultaneity and dynamic endogeneity. However, the intensity of bribery and the majority of (...) the forms of corruption were found to have negative impacts on firms’ financial performance. Hence, a typical approach using only a dummy variable for bribery might not adequately evaluate the impact of bribe intensity or even ignores the negative impacts of some types of bribes on firms’ financial performance. The findings suggest that anti-corruption measures are vital for the development of the Vietnamese private SMEs. (shrink)
