Abstract

The study was to investigate the effects of stimulus velocity and passer's skill level on anticipation timing performance. Fourteen subjects(seven novices and seven experts) were required to make a total 12 passes in coincidence with an experimentally manipulated moving light signal in randomly presented three different conditions(4m/s, $3m/s{\rightarrow}5m/s$, $5m/s{\rightarrow}3m/s$). Results of analyses showed that absolute error(AE) and constant error(CE) were greater in constant acceleration of the moving stimulus. In addition, experts were more accuracy and consistency than novices on absolute, constant and variable error(VE). These findings indicated that stimulus velocity served as the major determination of anticipation timing performance of passing.

이 연구의 목적은 불빛 자극의 이동속도가 농구 패스를 정확하게 예측하고 수행하는데 어떠한 영향을 미치는지를 알아보고 이러한 결과가 기술수준에 따라 어떠한 차이가 나타나는지 확인하는데 있다. 이를 위해 숙련자 7명, 초보자 7명의 대상에게 불빛 자극의 이동속도(4m/s, $3m/s{\rightarrow}5m/s$, $5m/s{\rightarrow}3m/s$)가 다른 실험과제 상황에서 불빛 자극이 목표지점에 도착하는 시점과 일치되게 체스트패스를 수행하도록 하였다. 실험과제는 각 자극조건 당 4회씩 총 12회가 무선으로 제시되었으며, 매 시행마다 예측 타이밍 수행의 차이를 확인하기 위해 절대오차, 항상오차 그리고 가변오차를 측정하였다. 연구 결과, 숙련자가 초보자에 비해 예측 타이밍의 정확성이 높은 것으로 나타났으며, 감속 및 등속 조건이 가속조건에 비해 타이밍 정확성이 높은 것으로 나타났다. 타이밍 수행의 경향을 측정한 항상오차는 숙련자가 초보자에 비해 적은 오차를 나타냈으며, 감속 조건이 가장 적은 오차를 나타냈다. 마지막으로 타이밍 수행의 일관성을 측정한 가변오차는 기술수준에 따른 주효과만 유의한 것으로 나타났다. 즉 숙련자가 초보자에 비해 수행의 일관성이 높은 것으로 나타났다. 이러한 결과를 종합해보면, 숙련자가 보다 예측 타이밍 수행능력이 높은 것으로 확인되었으며, 감속 조건이 다른 이동속도 조건에 비해 보다 낮은 오차를 보인 것으로 나타났다.
