在“视觉悬崖”上与婴儿一起工作，将避免跌落与自我产生的运动体验联系起来。Adolph（2002）关于婴儿对坡度和间隙可穿越性的感知的研究表明，学习避免跌倒与发生跌倒的姿势背景高度相关。例如，婴儿在爬行时学会了避免越过危险的斜坡，当他们开始走路时，必须重新学习这种避免。刚会走路的婴儿会避免穿越视觉悬崖的落差吗？20名行走前但有爬行经验的婴儿与20名年龄相仿的刚行走的婴儿对视觉悬崖的反应进行了比较。刚学会走路的婴儿避免走到悬崖的深处，甚至比会走路的爬行动物更加一致。因此，在视觉纹理的下降的背景下，我们的研究结果表明，一旦避免下降的爬行条件下建立，它是发育维持一旦婴儿开始行走。
Work with infants on the "visual cliff' links avoidance of drop-offs to experience with self-produced locomotion. Adolph's (2002) research on infants' perception of slope and gap traversability suggests that learning to avoid falling down is highly specific to the postural context in which it occurs. Infants, for example, who have learned to avoid crossing risky slopes while crawling must learn anew such avoidance when they start walking. Do newly walking infants avoid crossing the drop-off of the visual cliff? Twenty prewalking but experienced crawling infants were compared with 20 similarly aged newly walking infants on their reactions to the visual cliff. Newly walking infants avoided moving onto the cliff's deep side even more consistently than did the prewalking crawlers. Thus, in the context of drop-offs in visual texture, our results show that once avoidance of drop-offs is established under conditions of crawling, it is developmentally maintained once infants begin walking.
