神童能神多久？幼儿的自我意识和记忆
因为离奇的原因，我对人类的动物的行为有点知识，前不久我写过一篇短
文，叙述了人类出生时的智力极低，本能很少，远远不及动物出生已经具
备大量本能并且有初步生存能力。其实这正是人类更聪明的原因之一，人
类出生时候由于受到母亲骨盆大小的限制，大脑发育不全，需要很长时间
继续发育，这个时候因为有环境多样化的刺激，可以使得大脑的发育更丰
富多彩。那些大脑发育过早的神童，因为欠缺环境多样化的刺激，在生命
的后期很可能成为失败者。

所以先知们有句话：“在后面的要赶到前面”。

至于有些人要自称神童，我尊重他们的爱好.这里只是想说生命早期的过
度大脑发育，实际是一种退化，或者说动物化，不值得夸耀。

正常的幼儿在18个月前一般不知道自己是谁，更不用说什么故事和记忆。
三岁的儿童正常下有些简单不连贯的图片记忆，能有故事情节起码要到
4-5岁以后。

下面转一个著名的儿童自我意识的测验：

In 1979, Michael Lewis and Jeanne Brooks-Gunn conducted a sophisticated
version of the mirror test. They applied some blush to the noses of two
sets of children — 15- to 17-month-olds and 18- to 24-month-olds. The
idea: If the kids look in the mirror and see the blush on their nose,
they'll touch it or try to remove it in some way. However, this requires
the child to realize that the person in the mirror is himself. So what
happened? Just a few of the 15- to 17-month-olds actually reached up and
touched their noses, but the vast majority of the 18- to 24-month-old
children did it. So, these children must have recognized themselves in
the mirror.
