在Wired Mag的部落格上看到這篇文章：
We're running out of memory.
I don't mean computer memory. That stuff's half-price at Costco these days. No, I'm talking about human memory, stored by the gray matter inside our heads. According to recent research, we're remembering fewer and fewer basic facts these days.
This summer, neuroscientist Ian Robertson polled 3,000 people and found that the younger ones were less able than their elders to recall standard personal info. When Robertson asked his subjects to tell them a relative's birth date, 87 percent of respondents over age 50 could recite it, while less than 40 percent of those under 30 could do so. And when he asked them their own phone number, fully one-third of the youngsters drew a blank. They had to whip out their handsets to look it up.
很奇妙，可能因為現在資訊取得和儲存的方式不同，
因此年輕一輩的人沒有習慣去記一些東西，導致記憶的廣度可能縮小。
這樣以後IQ test的memory span這項測試就不太準確了。
未來的心理學家不是可以多一項工作機會：增強記憶訓練。
認知和神經科學家的新商機，we know your brain well !
不過，為什麼不是因為，年紀大的人早就對這些personal info聊若指掌，
反覆背誦了幾十年，所以提取的速度很快呢？
所以，如果從小就使用這些gadgets，不像年紀大的人從小就練習儲存很多記憶，
working memory的功能會比較弱嗎？
心理所的朋友誰要來做一下這個實驗？
