在卫生和个人卫生促进方面的许多政策关注集中在改变行为和增加对这些商品的需求上。然而，大规模干预措施的效果好坏参半，这在很大程度上是因为难以改变对根深蒂固的行为的态度。这项研究测试了围绕实验游戏构建的体验式学习练习是否可以用来改变对环境卫生和个人卫生的偏好。一个最小的协调游戏是适应环境卫生和个人卫生的设置，通过连接游戏的选择，以现实世界的投资决策和回报的健康和地位。来自泰米尔纳德邦农村20个村庄的个人被随机分配到三组中的一组：一组玩游戏，其中允许在回合之间进行交流，另一组玩游戏，其中禁止交流，控制组只完成调查。根据对治疗组的调查答复的比较，该游戏改善了与环境卫生和个人卫生有关的陈述偏好。当允许交流时，这种影响更大，在两个版本的游戏中，男性的反应平均比女性更强烈。这些结果表明，实验游戏可以是一个有价值的工具，不仅为决策的研究，但为提高参与者的知识和亲卫生偏好。
Much policy interest in sanitation and hygiene promotion focuses on changing behavior and increasing demand for these goods. Yet the effectiveness of large-scale interventions has been mixed, in large part because of the difficulty of changing attitudes on deeply rooted behaviors. This study tests whether an experiential learning exercise structured around an experimental game can be used to shift preferences around sanitation and hygiene. A minimum coordination game is adapted to the sanitation and hygiene setting by linking game choices to real-world investment decisions and payoffs in terms of health and status. Individuals from 20 villages in rural Tamil Nadu were randomly assigned to one of three groups: one that played a game in which communication between rounds was allowed, another that played a game in which communication was prohibited, and a control group that only completed a survey. Based on a comparison of survey responses across treatment arms, the game improved stated preferences in relation to sanitation and hygiene. This effect was larger when communication was allowed, and men responded on average more strongly than women across both versions of the game. These results suggest that experimental games can be a valuable tool not only for the study of decision making but for improving participants’ knowledge and pro-sanitation preferences.
