视觉注意的核心作用是生成早期视觉无法获得的物体描述。简单的例子是计算显示中的元素，或者决定一个点是在封闭轮廓的内部还是外部（Ullman, Cognition 18(1984) 97）。我们感兴趣的是对动态模式的高级描述——描述熟悉的物体经历刻板动作的运动——比如铅笔在桌面上弹跳，右边的蝴蝶，或者正在关闭的门。我们研究这些动作模式的感知是否由注意力作为高级动画或“精灵”来调节。我们研究了由简单的、刚性连接的运动点组成的显示的识别：要么是轨道运动的一对点，要么是模仿人类行走的11个生物运动点。我们发现，即使是最简单的动态模式的辨别也需要注意。(C) 2001 Elsevier Science B.V.版权所有
A central role of visual attention is to generate object descriptions that are not available from early vision. Simple examples are counting elements in a display or deciding whether a dot is inside or outside a closed contour (Ullman, Cognition 18 (1984) 97). We are interested in the high-level descriptions of dynamic patterns - the motions that characterize familiar objects undergoing stereotypical action - such as a pencil bouncing on a table top, a butterfly in Right, or a closing door. We examine whether the perception of these action patterns is mediated by attention as a high-level animation or 'sprite'. We have studied the discrimination of displays made up of simple, rigidly linked sets of points in motion: either pairs of points in orbiting motion or 11 points in biological motion mimicking human walking. We find that discrimination of even the simplest dynamic patterns demands attention. (C) 2001 Elsevier Science B.V. All rights reserved.
