一个飞球的可接性取决于接球手是否能及时拿到球;准确判断可接性必须反映空间和时间两个方面。两个实验研究了在有限信息拾取条件下的可捕捉性知觉。实验1比较了感性的判断与实际的捕捉，并发现，固定的观察员是穷人的感知catchableness，因为预期的信息缺乏有关运行能力。在实验2中，被试在视觉被遮挡之前看到了球轨迹的第一部分。在一个条件下，他们开始运行（好像接球）之前闭塞;在另一个条件下，他们保持静止。运动判断优于静止判断。这支持了这样一种想法，即感知依赖于运动学而不仅仅是几何学的身体特征的示能表示可能需要执行相关动作。
The catchableness of a fly ball depends on whether the catcher can get to the ball in time; accurate judgments of catchableness must reflect both spatial and temporal aspects. Two experiments examined the perception of catchableness under conditions of restricted information pickup. Experiment 1 compared perceptual judgments with actual catching and revealed that stationary observers are poor perceivers of catchableness, as would be expected by the lack of information about running capabilities. In Experiment 2, participants saw the Ist part of ball trajectories before their vision was occluded. In 1 condition, they started to run (as if to catch the ball) before occlusion; in another, they remained stationary. Moving judgments were better than stationary judgments. This supports the idea that perceiving affordances that depend on kinematic, rather than merely geometric, body characteristics may require the relevant action to be performed.
