How To Make A Prawn Trap?
A new study, led by David Whitney, a professor at the Center for Mind and Brain, and Department of Psychology, University of California at Davis, shows that professional tennis umpires are vulnerable to some optical illusion when you see bouncing balls in a line or near it. The misperception, despite being common in the visual system has rarely been documented in sports.
The error occurs because the perception of our brain is delayed a few milliseconds with respect to reality. While the brain is processing the image of a moving object, received their eyes, the object and continued their movement. To offset this effect, the brain makes its estimates of where to go next in order, based on its speed and direction of his career. Most times these assumptions are successful, but if the object is moving very fast and experienced sudden changes in direction, like a tennis ball bounces, assumptions can lead to erroneous assessments.
Whitney and his team reviewed a random set of 4,457 points from Wimbledon 2007. In all cases was recorded when the tennis ball landed near or on the line, and three watchers looked each play individually. They also discussed the instant replays. Whitney
hoped that the arbitrators saw the ball rebound in the direction of its original motion, which would see more balls that landed outside the line. The hypothesis has proved true. 84 percent of the 83 incorrect trials was due to errors observed in which the ball was declared "out" when it really was inside.

10 tips for tennis
3.La concentration focused on the ball, especially in the moment of impact because of this impact depends on the trajectory of it and, if we focus the attention towards the ball, we may fail no matter how prepared we had a strategy.
4.Reforzarnos to success: that is, when you make a good shot we recognize it as such, through what is known as a verbal reinforcement (eg Vamosssss!). When the result of a behavior is positively reinforced (understanding positive reinforcement as a reward), increases the likelihood of repeat behavior.
5.Aprender of errors: if an error to hit the racket to the ground or curse us, all we get is decentralized and exceed the appropriate level of activation. If, however, to make a mistake (eg ball into the net) analyze and visualize why (or gestualizamos) which should have been a blow not to fail (eg, opening more strings), then the error becomes a learning resource that will help us avoid this error, and so we took advantage of the error.
6.Marcarse objectives: one strategy to achieve the flow (state concentration close to the major stimuli of the game) is to set objectives, such as try three first serves in a row, or return three first service remains a focus for achieving this goal. 7.Autodiálogo
positive: positive talk from point to point is a good strategy to regulate itself, strengthened or planning. A key point is to avoid self-criticism at all costs. It is also essential to use words or phrases of self-reinforcement as a key to get further impetus.
8.Inducir good humor: if we are in a good mood to enjoy the game, we will be more positive self-talk and not react aggressively to the errors. For this forcéis suggest a grimace of a smile, as the muscle configuration requires grin smile makes the brain identified as positive and is responsible for secreting substances in the blood consistent with emotion. (W. James will ask you sad or cry because we are sad because we cry?)
9.Control activation status: all have an ideal trigger point is not the same for all people but is usually constant for the same person. If we are too fast, we can block and play with fear this would require a calm and self-talk especially relaxation breathing (breathe in slowly, hold a few seconds the air and out slowly.) If we are short of activation, we feel lazy, little desire to play, etc ... So we need to increase the activation, either by making a good warm up to increase heart rate and gritting his teeth as when we get angry, for the brain to identify the situation muscle as anger and order of release toxins in the blood energy to face the anger (eg adrenaline).
10.Es very important not to define a tennis match as a problem, but any competition must be conceptualized as a challenge, so, so, enjoy the process (the game) over the result (thinking future). 
1.Try not think of things that have nothing to do with tennis, bookmark, past (my opponent always wins or always win this rival, that ball was good and he has sung outside etc ...), future (5-3 to for / against this set because I've won / lost ...). The marker also can make us lose focus. The point is that none of these things help us to play tennis, because it does not tell us nor the track position, nor the technical movements and a strategy against the rival. These thoughts usually occur in moments of pause from point to point and even from game to game.
2.During the game, you should not think or analyze anything, you just have to play tennis. The analysis should be performed during breaks between points or between games, this analysis can be accompanied with some kind of ritual behavior (eg playing with the strings of the racket while we looking) in order to automate this behavior. During the game, simply to execute the intent, without time to analyze.
