与观看体育比赛时可能进行的眼球运动类似，该实验调查了参与者在跟踪多个物体时倾向于看向哪里。在记录眼球运动的同时，参与者追踪黑色背景上方框内随机移动的 8 个红点中的 1 个或 3 个。结果表明，参与者更多地关注更接近的目标而不是干扰因素。然而，在三目标试验中，注视点更接近目标形成的三角形的中心，而不是任何单个目标。这种以中心为中心的策略似乎反映出人们将目标分组为单个对象，而不是同时最小化所有目标的偏心率。在这里，我们发现观察者故意将眼睛聚焦在与他们所关注的物体不同的位置上，这可能是因为将这些物体表示为一个整体。 (C) 2007 Elsevier B.V. 保留所有权利。
Similar to the eye movements you might make when viewing a sports game, this experiment investigated where participants tend to look while keeping track of multiple objects. While eye movements were recorded, participants tracked either I or 3 of 8 red dots that moved randomly within a square box on a black background. Results indicated that participants fixated closer to targets more often than to distractors. However, on 3-target trials, fixation was closer to the center of the triangle formed by the targets more often than to any individual targets. This center-looking strategy seemed to reflect that people were grouping the targets into a single object rather than simultaneously minimizing all target eccentricities. Here we find that observers deliberately focus their eyes on a location that is different from the objects they are attending, perhaps as a consequence of representing those objects as a group.
