A follow-up study found that the children who were able to defer gratification by waiting for the second marshmallow were also later described by their parents as "competent adolescents", and achieved higher SAT scores than those who ate the marshmallow immediately.
Looking at my own family, I'm not sure whether Older Daughter would have waited for the second marshmallow, but I can confidently predict that Younger Daughter would have eaten the first marshmallow, and possibly taken a bite out of the furniture and the returning researcher as well.
There is nothing new under the sun (Ecclesiastes). It turns out that Bronson Alcott, transcendentalist, abolitionist, and the barking-mad father of Louisa May, performed a similar experiment on his own daughters, Anna and Louisa, then aged 5 and 4.
From Louisa May Alcott, Domestic Goddess:*
Bronson, knowing that both girls loved apples, left an unguarded apple near Louisa and her older sister, Anna, with the restriction that it belonged to him and the girls were not to eat it. Bronson knew that the girls would be tempted by this literally forbidden fruit, and he felt that the struggle would reveal important information about his daughters. Since Louisa ate the apple, and then unrepentantly stated that she had done so "cause I wanted it," Bronson's intended lesson in self-sacrifice was obviously only half learned. Anna did not eat the apple, and apologized for even thinking about it. Louisa, on the other hand, may have struggled with her will, but in the end she gave in to it, despite her fear of Bronson's displeasure.Which daughter grew up to be a famous and still widely-read novelist?
Adults favor obedient, disciplined children, and it is no surprise that such children are spoken of favorably by their parents and do well on the SATs. But the child who insists on her own point of view may have more to offer the world in the long run.
*Overachiever's footnote: I'm still looking for an authoritative source for the apple story. If you know of one, please let me know. I dimly remember a book or article called something like "Rebellion in the Nursery", about Bronson and Louisa Alcott, but I haven't been able to find it.
I don't like marshmallows (and never have). How does that fit into the experiment?
ReplyDeleteEven if it had been, say, a small piece of brownie (that I really do like) I would have been content to scarf down one now and not worry about not getting a second one because two is too many.
I also did quite well on the SATs--better, in fact, than I did in college. So I think there are a lot of other factors here and agree that what they're measuring may have little to do with actual life outcomes.
I left some details out of the description for the purpose of brevity. The kids were allowed to choose beforehand a favorite snack, so the kids who liked marshmallows were faced with a marshmallow and the kids who preferred pretzels were faced with a pretzel.
ReplyDeleteYou make an interesting point -- what if the kid was just not particularly hungry, and figured one marshmallow was enough?
Ah, that makes sense. I've heard of this type of experiment before, and I think I always just assumed the reward was arbitrary.
