Environment-led Attention To The The Athletes Visual Selective Attention To The Characteristics Of Research

The selective attention within the sport realm mean, athletes the direction of mental activity is various with action the technique completes the related incitement, and as to it's do a choice should a kind of consciousness of the answer regulate the appearance. Selective attention is the a kind of mental activity to regulate the mechanism, is very close vinculum to consciousness. Event-Related Brain Potentials (ERP) is totality of potentials in posterior synapses and reflects the signals of electroencephalographic activities simultaneous with stimulation. The ERPs technology is a valuable means to further investigate the cerebral mechanism of selective attention. The eye movement is study the method to provide a kind of instant research technique for the research of the sport realm. It can continuous and coinstantaneous record the behavior performance of the athlete. This research point investigate is the circumstance attentional type of athletes, selective attention of characteristics in the sport. Adopt the eye movement to record the method research athlete under the condition that the space clues turns to hint under and divide attention stimulate new different degree of the selective attention characteristics, find out the athletes different predominance attention type item to move the place of the difference on eye movement standards. Applied ERP to study athletes, nerve mechanism, the difference that investigates the circumstance attentional type of athletes and individual attentional type of athletes to find out what lead difference.Study the result enunciation: (1) Circumstance attentional type of athletes is better than the common people, have another information integrate process of have the initiative the effect obvious. The choice responds the speed ability obvious faster than common university student. The agility of selective attention is well. The ability is good to lower the attentional loss. The mistake rate is higher but keep within the scope of allow. All groups subjects express along with the increment of the mission difficulty, the resources of the devotion is more.(2) Circumstance attentional type of athletes, individual attentional type of athletes is in accordance with the common university student, they all influence by distraction stimulates (color), the clues hint and divide attention the variety regulation of three factors. All express at the valid clues hints to stimulate with new different target have the priority of the selective attention. Along with distraction stimulates the quantity increase, in addition to under the invalid clues- new color the difference stimulate constant circumstance the adoption series processing search, the other condition all searches the mode for the parallelism.(3) In distraction stimulates quantity and distraction stimulates novelty research, the circumstance attentional type of athletes and common university student compare, the eye that is in judgment process cognize mission move the mode characteristics is: fixation time shorter, fixation point number of times less, significant extent eyes saccades and seldom regressive eye movement. Fixation track more simple and concentration, fixation frequency higher, the every time gaze point continuously time is shorter, adopting quite well fixation strategy reasonablely. The information of circumstance attentional type of athletes processes the efficiency higher, at notice the characteristic and search to have characteristic strategically and more, can carry on the valid construction, can integrate more informations in the same time process, integrate the quantity higher.(4)In distraction stimulates quantity and distraction stimulates novelty research of ERP, find out is every group all activate the N85, P150 and N400s. The circumstance attentional type of athletes, N85, P150 and N400s is higher in than individual attentional type of athletes and common university students. The circumstance attentional type of athletes in different quantity distraction stimulates judgment of stimulate the mission, to the information measure of collect, accept the particularity felling information ability, information deliver with the integration ability of processing ability, the brain function etc, better than individual attentional type of athletes and common university students.(5)In distraction stimulates the quantity research, the circumstance attentional type of athletes average delitescence of the N85, P150 and N400 is shorter than individual attentional type of athletes and common university students, express a brain activate speed sooner. But in distraction stimulates the new different degree research, the circumstance attentional type of athletes delitescence of N85 obvious shorter in other two groups, express that circumstance attentional type of athletes in the earlier period that the selective attention to new different color activate quickly, but the delitescence of P150 and N400s have no obvious difference, noticing whole from the selective attention, activate to the color and did not express an obvious advantage on the brain mechanism.(6)From distraction stimulates quantity and distraction stimulates novelty research ERP, the circumstance attentional type of athletes, individual attentional type of athletes expressed with common university students compared, all amplitude under the condition of effectively hint is higher than invalid hint. circumstance attentional type of athletes while completing the different quantity to distraction stimulates the exciting mission judgment, first from Occipital sense of vision cortex quality to Temporal and Frontal dissemination, in the whole progress mission, each electrode of Occipital activation strength.(7)The eye movement method to respond from the behavior the cognition, judgment...etc. these level reflected the selective attention process. The method of ERP is then from the nerve physiology level up reflection correspond the time progress of affect the factor function. The eye movement and method of ERP combined, is the ideal instrument and method for on-line processing of selective attention.
