Joachim de Posada's speech on Ted

Yesterday, I watched the speech made by Joachim de Posada. It's about an interesting experiment.

Actually, I have alreadly read that experiment in a book two years ago. It was a reading comprehension at that time.

The experiment found a most important factor for success--ability of delay gratification(self-discipline). The researchers left the children alone in a room and gave them a candy and told the children that they would be back after 15 minutes. If, after the researcher came back, the candy was still there, the children got another one. When the children grew up, in a follow-up study, the researchers found that the kids who had not eaten the candy were successfull and the others were in trouble. In Chinese words is three-year-olds can see the old.

Hey, your written English is good! There were very few mistakes. :) Even English speakers will make similar mistakes.
