视运动对应过程的二维性

运动感知的基本过程是不同视图中相应元素的匹配。在这个对应过程中，元素之间的空间分离起着重要作用。目前的研究表明，相关分离是二维的、未解释的距离，这一发现对进行对应过程的水平有影响。将当前的发现与早期有关表观运动“最优性”的结果进行比较，得出结论：最优性不能作为对应强度的衡量标准。
A fundamental process underlying motion perception is the matching of corresponding elements in different views. In this correspondence process spatial separation between elements plays a major role. The relevant separation is shown by the current study to be the two-dimensional, uninterpreted distance, a finding that has an implication to the level at which the correspondence process is carried out. The current findings are compared with earlier results concerning ‘optimality’ of apparent motion to conclude that optimality cannot serve as a measure for the correspondence strength.
