1。how is he to know that any other marble of similar size will do just as well?yet he must assume that if he is to solve the probelem。Hewson made the functional equivalence of different marbles clear by playing a "swapping game "with the children。他怎么知道其他相似尺寸的弹珠也可以用?他一定是设想自己可以解决这个问题。HEWSON通过和孩子们一起玩弹珠游戏了解了不同弹珠的机能等价。2 adult in an african culture apparently can not do the kendlers"task either。but it lessens ,on the other hand ,when we lean that a task was devised which was strictly analogous to the kendlers's one but much easier for the african males to handle。非洲文化影响下的成年人显然无法完成kendlers任务。但是,从另一方面看,我们了解了需要为非洲男人们设计一个和kendlers相似,但简单的多的任务去完成。
