目的：研究高能量零食的传播图像与不健康饮食的潜在健康后果的厌恶图像配对对内隐和外显态度和食物选择行为的影响。设计图：参与者被随机分配到一个评价性条件反射（EC）程序，将零食的图像与潜在不良健康后果的图像配对，或者单独使用零食图像的对照条件。主要结果测量：内隐态度进行了评估前和干预后。干预后评估外显态度和食物选择行为。结果如下：条件反射干预使对能量密集型零食的内隐态度更加消极，这种影响在基线时对这些零食具有相对更有利的内隐态度的人中最大。在行为选择任务中，条件反射干预的参与者更倾向于选择水果而不是零食，这种关系由内隐态度的变化介导。结论：将潜在健康后果的厌恶图像与特定食物的厌恶图像一起呈现可以改变内隐态度，这会影响随后的食物选择行为。
Objective: To examine the effect of communicating images of energy-dense snack foods paired with aversive images of the potential health consequences of unhealthy eating, on implicit and explicit attitudes and food choice behavior. Design: Participants were randomly allocated to either an evaluative conditioning (EC) procedure that paired images of snack foods with images of potential adverse health consequences or a control condition that featured images of snack foods alone. Main Outcome Measures: Implicit attitudes were assessed pre- and post-intervention. Explicit attitudes and food choice behavior were assessed post-intervention. Results: The conditioning intervention made implicit attitudes toward energy-dense snacks more negative, with this effect greatest in those with relatively more favorable implicit attitudes toward these snacks at baseline. Participants in the conditioning intervention were more likely to choose fruit rather than snacks in a behavioral choice task, a relationship mediated by changes in implicit attitudes. Conclusion: Presenting aversive images of potential health consequences with those of specific foodstuffs can change implicit attitudes, which impacts on subsequent food choice behavior.
