초록

The purpose of the present research was to test Difference of Quiet Eye and visual search on Accuracy of Free-throws in Basketball expertise. This primary purpose of this study was to investigate the effects of free throw of closed motor skill, such as QE duration, QE-dwell time, Visual search rate and visual persistence of motion figures. The participants(n=10) were participated in men’s high school basketball player in D metropolitan. They were divided into two groups of the skilled and unskilled players for the test. Two g roups were tested on free throw. Two digital cameras, SONY Special Effects Generator (DSR-700A), E ye m ovement tracking s ystem, V ision-in-action coupling were u sed for the test. The collected data was estimated for comparing using an independe nt samples t-test of SPSS 23.0.
The results of this research on participants are as follows First, QE duration revealed statistically significant difference on QE duration of free throw. That is, the skilled players showed enduring longer than the unskilled players. Second, QE-dwell time revealed statistically significant difference on QE-dwell time of free throw. That is, the skilled players showed enduring longer than the unskilled players. Third, visual search rate(eye fixation times) revealed statistically significant difference during the time that the eye fixation on free throw. That is, the skilled players showed enduring longer than the unskilled players on the eye fixation times and less than the unskilled players on the visual search rate. Fourth, The rate of eye movement revealed statistically significant difference on free throw. That is, the skilled players showed less rate of eye movement than the unskilled players and enduring longer than the unskilled players on the eye fixation times.
