Previous studies (e.g., Wulf, Höss, & Prinz, 1998) have shown that motor learning can be enhanced by directing performers' attention to the effects of their movements ("external focus"), rather than to the body movements producing the effect ("internal focus"). The purpose of the present study was to test the hypothesis that increasing the distance between the body and the action effects might ...

Recently, discriminative correlation filter-based method becomes one of the popular directions in the field of visual tracking because of its computational efficiency and excellent performance, which make it especially suitable for real-time application. Most of them are focused only on the transition estimation. However, accurate scale estimation of the target plays a very important role in lo...

Applications on inference of biological networks have raised a strong interest in the problem of graph estimation in high-dimensional Gaussian graphical models. To handle this problem, we propose a two-stage procedure which first builds a family of candidate graphs from the data, and then selects one graph among this family according to a dedicated criterion. This estimation procedure is shown ...

Time varying environments or model selection problems lead to crucial dilemmas in identification and control science. In this paper, we propose a modular prediction scheme consisting in a mixture of expert architecture. Several Kalman filters are forced to adapt their dynamics and parameters to different parts of the whole dynamics of the system. The performances of this modular learning scheme...

Human vision has striking radial asymmetries, with performance on many tasks varying sharply stimulus polar angle. Performance is generally better the horizontal than vertical meridian, and lower upper these asymmetries decrease gradually deviation from meridian. Here, we report cortical magnification at a fine angular resolution around visual field. This precision enables comparisons between b...

The daylight in classrooms is a crucial aspect that affects the quality of learning environment and overall performance students. Visual arts, such as painting, sculpture, carving, textile design photography, require specific lighting conditions, which are different from regular classroom standards. Due to limited number studies this area, it necessary examine specificities types visual arts pr...

A scheme of a neural device intended for searching direct correlations between structures and properties of organic compounds without preliminary computation of molecular descriptors (that are invariant with respect to renumbering atoms in a molecule) is suggested. The invariance of a property with respect to renumbering atoms in a molecule is ensured by the architecture of the neural device, w...

The aim of the current study was twofold: (1) to validate the use of action sport cameras for quantifying focus of visual attention in sailing and (2) to apply this method to examine whether an external focus of attention is associated with better performance in upwind sailing. To test the validity of this novel quantification method, we first calculated the agreement between gaze location meas...

In sports, large amounts of data are measured and stored with the help of modern sensors and electronic devices. In particular, for endurance sports events, time-varying data are recorded and can be used to analyze the athletes’ performance. Finding patterns and issues can help better understand results in sports competitions, which is of interest for the athletes, sports managers, and trainers...
