前学龄测试：  ( A PRE-SCHOOL TEST FOR YOU) :
这巴士是向那个方向行走的   (Which way is the bus traveling) ?
是向左呢还是向右   (To the left or to the right) ?

你是不是没法判定啊      ( Can't make up your mind ) ?

很多美国前学龄儿童，都有看过这照片和给问同样的问题
( Pre-schoolers all over the United States were shown this picture and asked the same question.)

90％的前学龄儿童回答   ( 90% of the pre-schoolers gave this answer.)
"巴士是向左行走的"     ( "The bus is traveling to the left.")

当问，“为什么你认为巴士向左边行走的？”( When asked, "Why do you think the bus is traveling to the left?" )

他们回答说:     ( They answered)

"因为看不到（上）车的门 "  ("Because you can't see the door to get on the bus." )

你现在感觉到怎么样啊   ( How do you feel now ) ???
