Reducing the amount of motion information can surprisingly make motion look faster (e.g., motion behind Venetian blinds). We found that a textured pattern moving to the right at speeds ranging from 0.34 to 5.5°/s appeared to move 50% faster when viewed through a short (0.5°) compared with a long (4.5°) horizontal slot. Perceived speed varied inversely with the log of the slot length. We varied the length of rectangular apertures over a tenfold range and manipulated their size, shape, and orientation. We attribute the field-size effect mostly to landmarks provided by the ends of the slots, but we also examined temporal and spatial frequency and lateral inhibition of motion.
减少运动信息的量会出人意料地使运动看起来更快（例如，百叶窗后的运动）。我们发现，当通过短的（0.5°）水平狭缝与长的（4.5°）水平狭缝观察时，以0.34至5.5°/秒的速度向右移动的纹理图案似乎移动速度快了50%。感知速度与狭缝长度的对数成反比。我们将矩形孔径的长度在十倍范围内变化，并操纵它们的大小、形状和方向。我们将视野大小效应主要归因于狭缝末端提供的地标，但我们也研究了时间和空间频率以及运动的侧向抑制。
