Abstract

We investigated the role of saccades and microsaccades when different levels of basketball players were engaged in an ecological free-throw condition. All participants made more correct than incorrect shoots, with a movement time initiation shorter in amateurs than in near-expert groups. Near-experts had more stable gaze fixation than amateurs, with higher microsaccade rate and duration and lower peak velocity. Amateurs showed higher saccade rate, peak velocity, and amplitude than near-experts. The temporal sequence of near-experts' microsaccade rate increased after the saccade peak; on the contrary, in amateurs, the saccade peak is shown after the decrement in microsaccade rates. The spatiotemporal characteristics of microsaccades and saccades may reflect an optimal sampling method by which the brain discretely acquires visual information and can differentiate between participants who use a fixation before the critical movement time and participants who move their eyes to catch more visual cues to make decisions.

篮球运动员任意球投篮过程中的慢动作和微注视耦合。

我们研究了不同水平的篮球运动员在生态罚球条件下的囊视和微囊视作用。所有参与者的正确投篮次数都多于错误投篮次数，业余组的动作启动时间短于接近专家组。与业余选手相比，业余选手的凝视固定更稳定，微回旋率和持续时间更高，峰值速度更低。业余选手的囊状移动率、峰值速度和振幅均高于近乎专家。近熟练者的微注视率的时序在囊回峰值之后增加；相反，业余者的囊回峰值出现在微注视率下降之后。微回旋和囊回旋的时空特征可能反映了大脑离散获取视觉信息的最佳取样方法，可以区分在临界移动时间之前使用定点的参与者和移动眼睛捕捉更多视觉线索以做出决策的参与者。

期刊介绍： The Journal of Sport & Exercise Psychology (JSEP) is a peer-reviewed publication designed to stimulate and communicate research theory in all areas of sport and exercise psychology. JSEP emphasizes original research reports that advance our understanding of human behavior as it relates to sport and exercise. Comprehensive reviews employing both qualitative and quantitative methods are also encouraged, as well as brief reports of soundly designed research studies that are of special interest or importance. Areas of interest include research in social, clinical, developmental, and experimental psychology, as well as psychobiology and personality. Moreover, the terms sport and exercise may pertain to either the independent or dependent variables. Generally speaking, work on motor control processes, studies of sport as a social institution, or broader social issues are beyond the scope of JSEP. A wide variety of methods are acceptable for studying sport and exercise psychology topics.
