Carol Dweck, a psychology professor at Stanford University, found that kids respond positively to praise; they enjoy hearing that they’re talented, smart and so on. But after such praise of their innate abilities, they collapse at the first experience of difficulty. Demoralized by their failure, they say they’d rather cheat than risk failing again.

In recent eye-tracking experiments by the researchers Bradley Morris and Shannon Zentall, kids were asked to draw pictures. Those who heard praise suggesting they had an innate talent were then twice as fixated on mistakes they’d made in their pictures.

By age 4 or 5, children aren’t fooled by all the trophies. They are surprisingly accurate in identifying who excels and who struggles. Those who are outperformed know it and give up, while those who do well feel cheated when they aren’t recognized for their accomplishments. They, too, may give up.

It turns out that, once kids have some proficiency in a task, the excitement and uncertainty of real competition may become the activity’s very appeal.
