Abstract

The quiet eye is a characteristic of highly skilled perceptual and motor performance that is considered as the final fixation toward a target before movement initiation. The aim of this study was to extend quiet eye–related knowledge by investigating expertise effects on overall quiet eye duration among expert and near-expert basketball players, as well as to determine the relative contribution of early and late visual information in a basketball jump shot by comparing the timing components of quiet eye duration (early and late quite eye). Twenty-seven expert and near-expert male basketball players performed the jump shots. Gaze was recorded with the SensoMotoric Instruments eye tracking glasses and shooting performance accuracy was evaluated by scoring each shot on a scale of 1–8. Six infrared cameras circularly arranged around the participants were used to collect the kinematic information of the players. The performance accuracy, gaze behavior, and kinematic characteristics of the participants during the test were calculated. The experts with longer quiet eye duration had better performance in a basketball jump shot compared to the near-experts. Also the experts had longer early and late quiet eye duration than the near-experts. The results revealed a relationship between quiet eye duration and performance. The combined visual strategy is a more efficient strategy in complex far-aiming tasks such as a basketball jump shot.

静眼持续时间及其组成因素在复杂远瞄准任务中的作用
静眼是高度熟练的知觉和运动表现的特征,被认为是在运动开始前对目标的最后注视。本研究旨在探讨专业篮球运动员和准专业篮球运动员的专业技能对整体静眼持续时间的影响,以拓展静眼相关知识,并通过比较静眼持续时间(静眼早期和静眼晚期)的时间分量,确定篮球跳投中早期和晚期视觉信息的相对贡献。27名专业和近乎专业的男子篮球运动员表演了跳投。用SensoMotoric Instruments眼动追踪眼镜记录凝视,并以1-8分的评分来评估射击表现的准确性。6台红外摄像机环绕在参与者周围,用于收集运动员的运动信息。计算了参与者在测试过程中的表现精度、注视行为和运动学特征。静眼持续时间较长的专家在篮球跳投中表现优于准专家。专家比准专家有更长的早、晚静眼时间。结果揭示了静眼持续时间和表现之间的关系。在复杂的远距离瞄准任务中,如篮球跳投,组合视觉策略是一种更有效的策略。

期刊介绍: The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
