我们展示了在 40 所小学进行的一项现场实验的结果，涉及 8000 名儿童和 400,000 次儿童日观察，该实验测试了提供短期激励是否可以培养儿童习惯的形成。在三到五周的时间里，学生们会因为在午餐时吃一份水果或蔬菜而获得奖励。相对于 39% 的平均基线率，提供小额奖励使儿童至少吃一份水果或蔬菜的比例增加了一倍。干预结束后两个月，3 周治疗中学校的消费率仍高于基线 21%，5 周治疗中学校消费率仍高于基线 44%。这些发现表明，短期激励措施可以产生行为改变，这种改变在激励措施取消后仍然持续存在。 (C) 2015 Elsevier B.V. 保留所有权利。
We present findings from a field experiment conducted at 40 elementary schools involving 8000 children and 400,000 child-day observations, which tested whether providing short-run incentives can create habit formation in children. Over a 3- or 5-week period, students received an incentive for eating a serving of fruits or vegetables during lunch. Relative to an average baseline rate of 39%, providing small incentives doubled the fraction of children eating at least one serving of fruits or vegetables. Two months after the end of the intervention, the consumption rate at schools remained 21% above baseline for the 3 week treatment and 44% above baseline for the 5-week treatment. These findings indicate that short-run incentives can produce changes in behavior that persist after incentives are removed. (C) 2015 Elsevier B.V. All rights reserved.
