Lucy Cooke and her colleagues found that not only do kids eat veggies they previously resisted if bribed, but they continue to eat more of them even after several months (with no additional bribes forthcoming!) than their never-bribed peers. Interestingly, verbal praise (that’s a bribe?) worked just as well as stickers.
Over four hundred four- to six-year-olds tasted six vegetables, rated them for taste and then ranked them in order of liking. Whichever was their fourth-ranked choice became their target vegetable.
