I've lost control again MAY 21 2009
Jonah Lehrer, who is seemingly in a race with Michael Lewis these days to see who can write the most books and articles in a 12-month period, writes about self-control in the New Yorker...what it is, how it works, and how it affects things like achievement, happiness, etc. The article focuses on the efforts of Dr. Walter Mischel and the marshmallow test that he developed to measure self-control in young kids. With the marshmallow test, kids are given a mashmallow and they are told that they can eat it right away or, if they hold out, they can eat two marshmallows.
Once Mischel began analyzing the results, he noticed that low delayers, the children who rang the bell quickly, seemed more likely to have behavioral problems, both in school and at home. They got lower S.A.T. scores. They struggled in stressful situations, often had trouble paying attention, and found it difficult to maintain friendships. The child who could wait fifteen minutes had an S.A.T. score that was, on average, two hundred and ten points higher than that of the kid who could wait only thirty seconds.
I must have really underachieved on the SAT because as a four-year-old, I would have likely waited forever...I don't like marshmallows.
Update: Radiolab recently tackled the marshmallow test on their podcast. There is also marshmallow test footage on YouTube. (thx, michael)
Update: Lehrer answers readers' questions over on the New Yorker web site.
