測試：( A PRE-SCHOOL TEST FOR YOU) :
這巴士是向那個方向行走的 (Which way is the bus traveling) ?
是向左呢還是向右 (To the left or to the right)

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

很多美國前學齡兒童，都有看過這照片和給問同樣的問題
( Pre-schoolers all over the United States were shown this picture and asked the same question.)

90％的前學齡兒童回答 ( 90% of the pre-schoolers gave this answer.)

"巴士是向左行走的" ( "The bus is traveling to the left.")

當問，“為什麽你認為巴士向左邊行走的？”
( When asked, "Why do you think the bus is traveling to the left?" )

他們回答說 ( They answered) :
"因為看不到（上）車的門 " ("Because you can't see the door to get on the bus." )

怎麽樣, 你（現在）的感覺如何啊 ( How do you feel now ) ???
