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.
我们采用了一种变化检测方法，来评估传统“营养成分表”和包装正面营养标签中出现的营养信息的注意力优先级。结果提供了令人信服的证据，表明即使参与者没有被特别要求搜索营养信息，包装正面标签也比营养成分表更容易吸引注意力。此外，对包装正面标签内关键营养素的相对营养价值进行颜色编码，导致了营养信息注意力优先级的提高，但使用面部图标进行编码并没有显著增加对标签的关注度。最后，在不同的参与者样本中，包装正面设计的注意力优先级总体模式是一致的。我们的结果表明，颜色编码的包装正面营养标签会增加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启示意义。
