从运动学的角度，已经广泛地研究了将单个动作分成序列的问题。在这里，我们从知觉的角度探讨顺序行为的规划，研究伴随着视觉引导的顺序行为的感觉-运动转换。我们发现，只有当两个动作被计划快速连续进行，并因此被整合到一个共同的动作中时，视觉注意才会预先选择随后的目标。这会导致视觉注意力提前选择两个预期的目标位置。相比之下，在执行速度较慢的运动序列中，单个动作是一个接一个地编程，随后的动作目标只是在稍后的视觉上准备好(恰到好处)。后续目标位置的视觉选择关键取决于计划序列的速度：到达之间的延迟越长，最初对后续目标的视觉注意力就越少。(C)2011爱思唯尔有限公司。保留所有权利。
The chunking of individual movements into sequences has been studied extensively from a motor point of view. Here we approach the planning of sequential behavior from a perceptual perspective investigating the sensorimotor transformations that accompany visually guided sequential behavior. We show that visual attention pre-selects subsequent goals only if two movements are planned to be carried out in rapid succession and therefore are integrated into one common action. This causes visual attention to select both intended goal locations in advance. In contrast, in more slowly executed motor sequences, the single movements are programmed one-by-one and subsequent movement goals are only later visually prepared (just in time'). The visual selection of a subsequent goal location crucially depends on the speed of the planned sequence: the longer the inter-reach delay, the less visual attention is deployed to the subsequent goal initially.
