只有不到一半的美国人符合目前的水果和蔬菜摄入量建议。行为情感关联模型认为，与行为相关的感觉和情绪对决策有近端影响。横截面的证据支持该模型，并表明情感协会预测水果和蔬菜的消费。本研究的目的是测试是否存在因果关系的情感协会之间的水果和未来的水果消费行为，作为衡量零食选择任务。在对认知和情感变量进行基线评估后，采用内隐启动范式对被试（N = 161）对水果的情感联想进行了实验操作。水果的图像反复配对积极的，消极的，或中性的情感刺激。关键的结果测量是一个行为选择任务，参与者在水果和格兰诺拉麦片之间做出选择。在零食选择任务中，积极启动条件下的参与者比消极条件下的参与者更有可能选择一块水果而不是格兰诺拉麦片。他们选择水果的可能性也是中性条件下的两倍。自我报告的情感关联或认知信念没有变化。这些研究结果提供了情感关联对行为的隐性和直接影响的进一步证据，表明需要将情感在健康决策模型中的作用，以及针对情感关联与健康相关行为的干预策略的潜在效用。
Fewer than half of Americans meet current recommendations for fruit and vegetable intake. The behavioral affective associations model posits that feelings and emotions associated with a behavior are a proximal influence on decision making. Cross-sectional evidence supports the model and suggests that affective associations predict fruit and vegetable consumption. The purpose of this study was to test whether a causal relation exists between affective associations about fruits and future fruit consumption behavior, as measured by a snack selection task. Following a baseline assessment of cognitive and affective variables, participants’ (N = 161) affective associations about fruits were experimentally manipulated with an implicit priming paradigm. Images of fruits were repeatedly paired with positive, negative, or neutral affective stimuli. The key outcome measure was a behavioral choice task in which participants chose between fruit and a granola bar. Participants in the positive prime condition were three times more likely than those in the negative condition to select a piece of fruit over the granola bar alternative in the snack selection task. They were also twice as likely as those in the neutral condition to select fruit. There were no changes in self-reported affective associations or cognitive beliefs. These findings provide further evidence of the implicit and direct influence of affective associations on behavior, suggesting the need to both incorporate the role of affect in health decision making models, as well as the potential utility of intervention strategies targeting affective associations with health-related behaviors.
