The purpose of this study was to examine how the length of saccadic reaction times (SRTs) affect the timing error of coincident responses. Three male subjects each participated in four kinds of tasks consisting of eight blocks of 30 trials. In the beginning, the subjects kept gazing at a fixation point on the right side of a computer monitor. When a target began to move horizontally from a starting point (near or on the fixation point) to left at a constant velocity, they made a saccadic eye movement to pursuit it as quickly and accurately as possible. After then, they pressed a push button at the moment they supposed that the target just arrived at a given point through a masking zone making it invisible. Four visual stimulus patterns consisted of two fuzzy vision conditions and two clear vision conditions. Fuzzy vision strategies make low state of focused visual attention by separating a viewpoint, from a visual target, with making it blurry and/or double imaged, and have possibility to evoke the express saccade easily. The repeated-measured two way ANOVA was employed to analyze SRTs and the absolute and constant errors of anticipated responses to the four tasks. As a result, the fuzzy vision task showed saccades with extremely short reaction times, small absolute errors, and stable constant errors close to zero. Such a fuzzy vision strategy, in contrast with a clear vision strategy, would improve motor performance in high-speed ball games.
