Gaze behavior of elite basketball athletes was determined as they performed 10 accurate and 10 inaccurate free throws (FTs) to a regulation basket wearing an eye tracker that permitted normal accuracy. Experts (mean FT = 78%) differed significantly from near experts (mean FT = 56%) in having a longer fixation on the target combined with an earlier fixation offset during the shooting action. These results, which depart from current models of near aiming, are tentatively explained using a location-suppression hypothesis. During the early phases of the aiming action, a fixation of long duration is needed on a specific target location. As the aiming action is then performed, vision appears to be a liability and is suppressed.
研究人员使用一款能保证正常准确性的眼动追踪器,测定了精英篮球运动员在进行10次准确罚球和10次不准确罚球时的注视行为。专家组(罚球命中率均值为78%)与准专家组(罚球命中率均值为56%)存在显著差异,专家组在投篮动作中对目标的注视时间更长,且注视偏移更早。这些结果与当前的近瞄准模型不同,暂用位置抑制假说进行解释。在瞄准动作的早期阶段,需要在特定目标位置进行长时间注视。然后在执行瞄准动作时,视觉似乎成为了一种负担并被抑制。
