我们使用一种变化检测方法来评估出现在传统的“营养事实面板”和包装前营养标签上的营养信息的注意力优先顺序。结果提供了令人信服的证据，表明包装正面的标签比营养事实小组更容易吸引人们的注意，即使参与者没有专门负责搜索营养信息。此外，在包装正面标签内对关键营养素的相对营养价值进行颜色编码会增加对营养信息的关注优先顺序，但使用面部图标编码并不会显著增加对标签的关注。最后，在不同的参与者样本中，注意优先顺序的总体模式在不同的受试者中是一致的。我们的结果表明，颜色编码、包装正面的营养标签增加了对包装食品营养信息的关注，这一发现对当前有关标签变化的政策讨论具有意义。
We used a change detection method to evaluate attentional prioritization of nutrition information that appears in the traditional “Nutrition Facts Panel” and in front-of-pack nutrition labels. Results provide compelling evidence that front-of-pack labels attract attention more readily than the Nutrition Facts Panel, even when participants are not specifically tasked with searching for nutrition information. Further, color-coding the relative nutritional value of key nutrients within the front-of-pack label resulted in increased attentional prioritization of nutrition information, but coding using facial icons did not significantly increase attention to the label. Finally, the general pattern of attentional prioritization across front-of-pack designs was consistent across a diverse sample of participants. Our results indicate that color-coded, front-of-pack nutrition labels increase attention to the nutrition information of packaged food, a finding that has implications for current policy discussions regarding labeling change.
