One characteristic of perceptual expertise in sport and other domains is known as 'the quiet eye', which assumes that fixated information is processed during gaze stability and insufficient spatial information leads to a decrease in performance. The aims of this study were a) replicating inter- and intra-group variability and b) investigating the extent to which quiet eye supports information pick-up of varying fields of vision (i.e., central versus peripheral) using a specific eye-tracking paradigm to compare different skill levels in a dart throwing task. Differences between skill levels were replicated at baseline, but no significant differences in throwing performance were revealed among the visual occlusion conditions. Findings are generally in line with the association between quiet eye duration and aiming performance, but raise questions regarding the relevance of central vision information pick-up for the quiet eye. Key pointsInvestigation of throwing performance and quiet eye duration in dart throwing under several vision conditionsFirst investigation using a dynamic occlusion paradigm, manipulating field of vision in situReplication of previous findings concerning throwing performance and quiet eye durationNew insights about the role of central (and peripheral) vision concerning the quiet eye phenomena.
运动和其他领域的感知专长的一个特征被称为“安静的眼睛”,它假设注视信息在注视稳定性期间被处理,而空间信息不足会导致表现下降。本研究的目的是 a)复制组内和组间的可变性,b)使用特定的眼动追踪范式调查安静的眼睛在多大程度上支持不同视野(即中央和周边)的信息采集,以比较飞镖投掷任务中的不同技能水平。在基线时复制了技能水平之间的差异,但在视觉遮挡条件下没有发现投掷表现的显著差异。研究结果通常与安静眼睛持续时间和瞄准表现之间的关联一致,但对中央视觉信息采集对安静眼睛的相关性提出了质疑。
