研究人员对优秀篮球运动员的凝视行为进行了测定，让他们戴上眼动仪，对一个标准篮筐进行10次准确罚球和10次不准确罚球。专家（平均FT = 78%）与近专家（平均FT = 56%）在射击动作中对目标的固定时间较长，并且固定偏移较早，这一点有显著差异。这些结果偏离了当前的近距离瞄准模型，我们暂时用位置抑制假说来解释这些结果。在瞄准动作的早期阶段，需要对特定的目标位置进行长时间的固定。当瞄准动作被执行时，视觉似乎是一种负担，被抑制了。
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.
