回想一下你绘画的经验，如果你想在同一块画布或一页纸上展示远距离的物体，你会怎么做？画小一点儿！原因是越远的物体在我们的视网膜上的成像就会越小。
Do you draw or paint? If you want to make something appear far away on a two-dimensional canvas or piece of paper, how do you do that? You make it smaller. The reason this works is that as objects move farther away, their image on the retina of our eye gets smaller.
但是，即使物体成像变小了，我们却不会认为它真的缩小了。如果你描述一位朋友走远了，不会说：“噢，天啊！她缩小了！！”因为你的大脑会做出正确的判断，这就是视觉恒常性。
However, even though the image is getting smaller, we don’t think the object is really getting smaller. If you are talking to a friend and she starts walking away, you don’t say, “Oh my! She’s shrinking!” Your mind makes whatever adjustments are necessary. This is what is referred to as size/shape constancy.
我们每天都在使用视觉恒常性，所以我们理所当然的认为这是一种本能。但请一定了解，这种能力不是我们与生俱来的。事实上，视觉恒常性是我们必须通过后天的学习才能具备的。它是我们在降生的最初几个月里，通过各种相关的经验才能获得的能力。
While the capacity to make these adjustments is something we use every day and take for granted, it is important to realize that it is not something that is present at birth. It is actually a skill that has to be learned. And it is through a variety of relevant experiences during the first months of life that babies gradually acquire size/shape constancy.
所以，不论何时，你和你的小宝贝来到悦宝园早教中心，参加那些看似简单的情感和体能课程时，请记住，那些对于你是再普通不过的技能，对他们来说却是复杂和具挑战性的。在悦宝园早教中心，你可能只是享受一段美好的时光，而你的宝贝，却正在学习将会让他们受益终生的能力。
So whenever you and your little one are immersed in seemingly simple sensory and physical activities at Romp n’ Roll, keep in mind that what may be relatively mundane for you is complex and challenging for her. And while you may be merely having a good time, she is learning some critical lessons that will serve her well for the rest of her life.
