Eye Movement Study on the Information Processing within the Sight Range of Football Players

For athletes, the fixation account on the central information is less than that on peripheral information; the fixation account of the expert group is more than that of the novice group. For the expert group, the saccade distance of peripheral information is smaller than that of central information. The fixation account of the expert group is significantly larger than that of the novice group; the differences of indexes between the central and peripheral information is not significant. This shows that the expert group adopts strategies of concentrated fixation and search of central information while adopts strategies of rapid and large-scope scanning of peripheral information. The expert group has a stronger information processing capability, the duration time of secondary fixation point is shorter, the fixation account is more and the duration time of fixation is short. There is significant difference between the expert group and the novice group. There is significant difference between the expert group and the common group in saccade distance. Different materials affect the duration time of secondary fixation point, fixation account, the duration time of fixation and saccade distance. For the athletes in different levels, from expert to novice, the cognitive difficulty of the same task is increasing.
