At what age do people's intelligence peak?

When people are getting old, they will inevitably suffer from cognitive decline such as poor memory as well as decline in learning ability. Does IQ really have anything to do with age? At what age do people reach the peak of intelligence? The Scientific American Website published an article on the results of a research at the Harvard University and Massachusetts Institute of Technology. The study was conducted by using online cognitive games that everyone could participate in. The results show that there is no exact age in which most people's brain functions reach their peak. For example, our ability to process information quickly reaches its peak between the ages of 18 and 19; the peak of short-term memory occurs around 25 years old, and can last for 10 years, and then decreases slowly; our ability to examine a man's language and observe his countenance will reach the highest level between 40 to 50 years old;and our comprehensive knowledge level reaches at its peak in 50 years old . After that, our levels decline slightly before the age of 60, and eventually decline again around the age of 75.

In addition, the peak age of intelligence activities will change, for example, the more accomplishment the Nobel prize winner obtains, the older the age is., and this situation is the same in every field. The article said that  the most creative age of physicist is at an average age of 48, that is to say, even if you can't remember where the key is, it won’t hold you up creating brilliance when inspiration strikes.

人上了年纪，难免会出现记性不好、学习能力下降等认知衰退的情况。人的智商和年龄大小真的有关系吗？人到底在几岁会到达智力的巅峰呢？《科学美国人》网站发表了一篇文章，介绍了哈佛大学和麻省理工大学的研究成果。这项研究用了网上人人都可参与的认知游戏来进行测试。结果表明，并不存在一个能够让多数人的大脑功能达到巅峰的确切年龄。比如，我们快速处理信息的能力在18至19岁左右达到顶峰；短期记忆的巅峰大约出现在25岁，并且能保持10年之久，然后才缓慢下降；我们察言观色的能力要到40至50岁才算是最高水平；而我们的综合知识水平，在50岁左右到达巅峰。之后，我们的各项水平在60岁前轻微下降，并最终在75岁左右再次下降。

此外，智力活动的巅峰年龄也会有所变化，比如，诺贝尔奖得主获得最重要的成果时的年龄越来越大，这种情况在各个领域都一样。文章说，物理学家最具创造力的年龄平均在48岁，也就是说，就算你记不住钥匙放哪了，也不耽误你在灵感来临的时候创造辉煌。
