The purpose of the present research was to test Difference of Quiet Eye Duration on Accuracy of Free-throws in Basketball based on Ericsson(
1996)’s study in a previous study.
* A thesis submitted to the committee of Graduate School, Chungnam National University in a partial fulfillment of the requirements for the degree of master of Physical Education conferred in February 2016.
This primary purpose of this study was to investigate the effects of free throw of closed motor skill, such as QE duration, QEDT, Visu
al search rate and visual persistence of motion figures. The participan
ts(n=10) were participated in men’s high school basketball player in D metropolitan. They were divided into two groups of the skilled and u
nskilled players for the test. Two groups were tested on free throw. Two digital cameras, SONY Special Effects Generator (DSR-700A), E
ye movement tracking system, Vision-in-action coupling were used fo
r the test.
The collected data was estimated for comparing using an independe nt samples t-test of SPSS 21.0. The results of this research on partic
ipants 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, QEDT revealed statistically significant difference on QEDT 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.
Key words : free throw, Quiet Eye duration, Quiet Eye dwell time.
