一个模型的视觉明显的运动是从4个观察路径选择模糊显示，照明点的明显的运动，原则上，可以被认为是沿着许多可能的路径：（a）虽然运动在每个路径是清晰可见的，当它的刺激是孤立的，运动通常是看到只有一个路径时，2个或更多这样的刺激相结合（竞争）。(b)路径选择几乎与观看距离无关（比例不变性）。(c)在路径i和j之间的过渡点处（其中沿沿着i和j同样可能感知到视在运动），时间t和沿路径沿着的连续点之间的距离d由对数线性d/t关系描述。(d)当沿路径的连续元素沿着在方向或大小上不同时，沿该路径的感知运动沿着不一定弱于沿完全由相同元素组成的路径的运动沿着。该模型是强度理论的一种形式，其中具有最大强度的路径成为主导路径。(27参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
A model of visual apparent motion is derived from 4 observations on path selection in ambiguous displays in which apparent motion of illuminated dots could, in principle, be perceived along many possible paths:(a) Whereas motion over each path is clearly visible when its stimulus is presented in isolation, motion is usually seen over only 1 path when 2 or more such stimuli are combined (competition).(b) Path selection is nearly independent of viewing distance (scale invariance).(c) At transition points between paths i and j (where apparent motion is equally likely to be perceived along i and j), the time t and distance d between successive points along the paths are described by a log linear d/t relationship.(d) When successive elements along a path differ in orientation or size, the perceived motion along this path is not necessarily weaker than motion along a path composed entirely of identical elements. The model is a form of strength theory in which the path with greatest strength becomes the dominant path.(27 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
