    For the purpose of this article, research on meditation concerns research into the psychological and physiological effects of meditation using the scientific recent years, these studies have increasingly involved the use of modern scientific techniques and instruments, such as fMRI and EEG which are able to directly observe brain physiology and neural activity in living .   In each of the experiments, we used a combination of performance indices to assess mental workload, including RT and accuracy, in response to a peripheral light detection task (the Detection Response Task [DRT]; ISO, ), subjective workload measures from the NASA Task Load Index (NASA-TLX; Hart & Staveland, ), and physiological measures Cited by:

    Failure subjects were then assigned to one of three self-awareness conditions: One group was forced to watch a video clip of themselves failing on the problem-solving task, one group was asked to watch a distracting video clip on bighorn sheep, and the final group was asked to sit quietly for 10 minutes. The integration of very high-tech equipment into standard operations is a radical change in the challenges faced by the infantry soldier. In addition, the battlefield, in all its forms, remains a place of extreme stress.

Flying Training Division.; Arizona State University.]. The initial physiological indices were acquired as a baseline before the experiment.

During experiment, the physiological indices were collected during each phase (level of task complexity), and the NASA-TLX questionnaire was conducted after each phase to evaluate the subjective MWL of different levels of task by: 5. The results indicate that different complexity levels of driving task have a significant effect on the driver’s performance, and the predictive performance model integrates different.

Although academic performance stems from a complex interaction between intellect and contextual variables, health is a vital moderating factor in a child's ability to learn.

The idea that healthy children learn better is empirically supported and well accepted (Basch, ), and multiple studies have confirmed that health benefits are associated with physical activity, Author: Harold W.

A growing body of literature demonstrates that engaging in sport regularly and maintaining an active lifestyle have a positive impact on cognition. The purpose of this study was to examine the influence of sport experiences and physical activity on attention, and explore whether the type of sport can impact differently on the neuroelectric system using Event-Related Potentials (ERPs).Author: Mohamed Aly, Mohamed A.
