The aims of the present review were to (i) provide a critical overview of the current literature on the effects of mental imagery on muscular strength in healthy participants and patients with immobilization of the upper extremity (i.e., hand) and anterior cruciate ligament (ACL), (ii) identify potential moderators and mediators of the “mental imagery-strength performance” relationship and (iii...

Providing an athlete with the mental tools necessary to build, maintain or regain confidence can aid the athlete in achieving peak, or optimal performance. Many of the procedures and practices in mental training involve technology. This technology, ranges from digital video and audiotapes, to simulations and virtual reality. In this article the authors review the areas of sport efficacy and spo...

Mental fatigue is often characterized by reduced motivation for effortful activity and impaired task performance. We used subjective, behavioral (performance), and psychophysiological (P3, pupil diameter) measures during an n-back task to investigate the link between mental fatigue and task disengagement. After two hours we manipulated the rewards to examine a possible reengagement effect. Anal...

[Purpose] The final purpose of the present study was to propose easy and quick mental rotation task. Since subjects can easily understand mental rotation task that they have to do, the task is considered to be available in particular children. However, existing mental rotation task using specific software asked subjects more than ten trials per one pictured stimulus, meaning that relatively lon...

Psychology is increasingly involved with athletes, coaches, and trainers to enhance athletic performance through improved physical and mental training. Knowledge of psychology is essential for understanding each individual's motivation and developing that motivation to an ...

A trivalent diagram is a connected graph with cyclic orientations and degree conditions on its vertices. It is the combinatorial description of an unembedded trivalent ribbon graph. We shall describe and analyze an algorithm giving an exhaustive list of trivalent diagrams of a given size. The list being nonredundant in that no two diagrams of the list are isomorphic. The algorithm will be shown...
