东亚人 尼安德特基因 世界最高(方肘子亲自刮了点细胞去测过),尼安德特人的特点
是擅长狩猎、但人际交流社会组织能力奇弱,所以visio-spatial IQ很高、verbal IQ
很弱,不奇怪。

东亚人当农民是因为后天环境给的条件适合种地(对比阿拉伯人就只能养骆驼),而基因
是先天的。
东亚人的尼安德特基因有visio-spatial方面的优势,围棋之类的需要空间想象力的智
力运动可以轻松垄断;但verbal方面有劣势,人际交往会谈领军的能力都不见得比黑人强

来自主题: Military版 - 奥赛都是刷题刷出来的
我先用一个四年级以上数学的例子,比如等差数列的求和公式的记忆。
我觉得记忆公式本身并不错,人总是用自己的长处,如果 phonological loop 更强大
,那显然记忆等差数列求和公式多块好省。
但 spatial / formal thinker,常常会觉得在大脑里,出现一个梯形,复制成两个,
然后对称拼出个矩形,然后利用其 clue 写出公式(当然遇上 AMC 12 不一定需要公式
,直接出答案可能更快)。这种用 visuospatial sketchpad 的方式,更得心应手。

来自主题: Military版 - 金牌和状元大多也是普通人
学习方法而言,数理竞赛里的黑马型选手(也就是依赖 spatial / formal thinking
的 visuosketchpad),有高中到大学本科硕士以及一辈子不需要换学习方法的优势。
。。当然代价是分数稍微低一些,万金油不变应万变的学习方法的缺点是,百米赛跑缺
乏最后一秒优势。


: 大学里各省的状元出色的很少。 我不知道有没有状元能在本科出类拔萃的。

: 我知道的几个省状元在本科连班级前10名都费劲。

: 这个吧,一个是高考大省小省的差别。 我本科碰见的超级大牛绝大部分来自江
苏湖北

: 四川安徽, 排名分先后。 这几个省拿状元可不容易。 而且状元和前十的区分

: 另外本科里的学习的方式和高中已经很大差别了。 高中那套吃不开了。

: 相对来说本科前几名后来混academic基本都能有所建树

不是高斯娃的一年级普通娃只有 concrete operation。而没有复杂的 formal
operation 能
力,很难理解 3*3 这种 xform geometry based spatial perception。
当然试试无妨,没必要强迫。简单的直接拿三角形玩具拼就是了。但用处不大,因为纯
concrete operation 学校老师会教。

四年级以下数学我不太会,目前教小娃也是边摸索边实践。
不过总体大方向,我觉得四年级以下课后数学还是以 puzzle math 为主,不要杀了兴
趣。。。目标可能更侧重于 improve math working memory and spatial perception
/ number sense,当然缺点就是没有短期效果,也是赌。

Abstract
Identifying the phenotypes underlying postzygotic reproductive isolation is
crucial for fully understanding the evolution and maintenance of species.
One potential postzygotic isolating barrier that has not yet been examined
is learning and memory ability in hybrids. Learning and memory are important
fitness-related traits, especially in scatter-hoarding species,... 阅读全帖

图中横坐标是挪威青年男子的出生年份,纵坐标是他们的平均智商。不考虑其中短期的
波动,整个的大趋势非常明显 ——
1960年以后出生的挪威人的智商越来越高,到1975年达到顶点 —— 而1975年以后出生
的挪威人的智商越来越低。这是典型的逆转弗林效应,而且出生年份也和前面说的丹麦
、英国和德语国家的情况差不多。那如此说来,岂不是说1975前后年出生的这一拨人,
可能是欧洲发达国家史上最聪明的一代!
那怎么证明这是个实质性的效应而不只是统计现象呢?研究者拥有这么多的数据,他们
可以专门考察各个家族*内部*的智商变化情况。
比如说,一个家庭在十年内生了三个孩子。那如果弗林效应是对的,孩子应该越来越聪
明,老三的智商就应该比老大高一点。当然有些人认为老大的智商通常高于他的弟弟妹
妹 —— 可能因为头一胎的先天营养更好 —— 那即便如此,因为有了弗林效应,老三
和老大的智商差距应该并不大。弗林效应肯定是提高老三的智商,对吧?
但是研究者发现,即便只在家庭内部比较。1975年以后出生的孩子中,老三不但不如老
大聪明,而且智商差距还是*越来越大*的趋势。
研究结果是从1975年到1991年,家庭内... 阅读全帖

或者举个实际的例子,解 AIME 数学邀请赛 15 道心算填空题,其关键在于心算。
而心算 AIME 三角几何题,实际上在人大脑的 visual spatial sketch pad 里,真真
切切的虚构了空间几何体,不仅如此,还对此进行各种属数学操作变形,最终写出解析
式子,不管对错。
但另一方面,这个几何体从来没有在真实世界里存在过,只是一个幻想。尽管这个幻想
真实到哪种数学操作可以进行,哪一种不能进行,像真实空间里的物体那样逻辑分明和
细节完整。但那个只是幻想,不是现实。
如果无法区分幻想现实,就是 schizophrenia。
不过数学和物理专业,确实是 schizophrenia 的高危人群,也是事实啦。


: 你这个理论不是对所有人都适用。

: 原因是人类区分幻想和现实的能力,存在很大个体差异。

: 严重无法区分幻想和现实的,1% 的人群,叫 schizophrenia。

Progressive feminists are not going to be happy with this study:
A pioneering study has shown for the first time that the brains of men
and women are wired up differently which could explain some of the
stereotypical differences in male and female behaviour, scientists have said.
Researchers found that many of the connections in a typical male brain
run between the front and the MenWomenDifferentback of the same side of the
