지각된 과제 난이도가 숙련자의 운동 수행 메커니즘에 미치는 영향: 시각적 착시를 중심으로

초록

Purpose: This study aimed to investigate the effects of visual illusion (Ebbinghaus illusion) on skilled golfers’ performance ability and aiming time in putting situations. Method: Ten golf-major university students holding professional qualifications(KPGA, KLPGA) participated in the study. The experiment was conducted in an indoor putting practice facility under five target conditions: standard hole, physically larger hole, physically smaller hole, perceptually larger hole, and perceptually smaller hole. Each participant performed 10 putts per condition from a distance of 2 meters, totaling 50 putts. Performance ability was measured by accuracy (radial error) and consistency (standard deviation of radial error), while aiming time was calculated from the moment the ball was placed until the hand was released. Data were analyzed using one-way repeated measures ANOVA. Results: Significant differences were found in aiming time and accuracy depending on target type. Larger and perceptually larger targets resulted in shorter aiming times but reduced accuracy, whereas smaller and perceptually smaller targets led to longer aiming times but improved accuracy. Consistency was generally maintained across most conditions, with only the larger target showing slightly greater variability compared to the standard target. Conclusion: This study confirmed that perceived target size influences aiming time and accuracy in skilled golfers, while consistency is only minimally affected. These findings support theoretical frameworks such as Attentional Control Theory (ACT), the speed-accuracy trade-off and attentional focus models, and provide practical implications for strategic guidance in sports training that incorporates perceptual manipulation.
