感知告知人们行动的机会及其相关成本。为此，明确的空间布局意识的变化不仅与相关的光学和眼动变量，但也作为一个功能的成本与执行预期的行动。虽然外显意识在这方面是可变的，但直接针对直接环境的视觉引导的行动则不是。当与步行相关的代谢成本增加时--也许是因为一个人背着沉重的背包--山看起来更陡，到目标的距离看起来更远。当一个人站在高高的阳台上时，与地面的明显距离与一个人对坠落的恐惧有关。感知空间布局将世界的几何形状与行为目标以及与实现这些目标相关的成本相结合。
Perception informs people about the opportunities for action and their associated costs. To this end, explicit awareness of spatial layout varies not only with relevant optical and ocular-motor variables, but also as a function of the costs associated with performing intended actions. Although explicit awareness is mutable in this respect, visually guided actions directed at the immediate environment are not. When the metabolic costs associated with walking an extent increase-perhaps because one is wearing a heavy backpack-hills appear steeper and distances to targets appear greater. When one is standing on a high balcony, the apparent distance to the ground is correlated with one's fear of falling. Perceiving spatial layout combines the geometry of the world with behavioral goals and the costs associated with achieving these goals.
