我们研究了视觉辅助工具对食品安全判断的影响，并结合个体认知差异。在这项研究中，参与者（900名日本女性）以书面形式或书面形式伴随着视觉辅助（功能图或插图）的农药残留的解释，并要求对含有农药残留的食品的安全性做出判断。一项基于网络的调查结果显示，对非专业人士来说，对食品安全的判断非常困难，因为他们对用于描述农药残留量的技术术语了解甚少。我们发现，虽然视觉援助显示其功能关系并没有提高对技术术语的理解，说明视觉援助导致了更好的理解和更准确的判断安全。我们还发现，虽然用主观计算量表测量的认知特征（Fagerlin等人，2007 b）和认知反射测试（Frederick，2005）与食品安全判断相关，无论认知特征如何，使用视觉辅助工具都会改善判断。这些结果表明，虽然不是所有的视觉辅助工具，提高食品安全信息的理解，适当设计的视觉辅助工具，并在考虑如何传达食品安全信息时，应考虑到认知特征产生的个体差异，对食品安全的判断。
We examined the effect of visual aids on judgments on food safety in conjunction with individual cognitive differences. In this study, participants (nine hundred Japanese women) were presented with explanations of pesticide residue either in written form only or in written form accompanied by a visual aid (functional graph or illustration), and were asked to make judgments on safety for foods that have pesticide residue. Findings through a web-based survey showed that judgments on food safety were highly difficult for laypeople since they had little knowledge of the technical terms used to describe amounts of pesticide residue. We found that although a visual aid showing their functional relationship did not improve understanding of the technical terms, an illustrated visual aid led to both improved understanding and more accurate judgments on safety. We also found that although cognitive traits measured with the subjective numeracy scale (Fagerlin et al., 2007b) and the Cognitive Reflection Test (Frederick, 2005) correlated with judgments on food safety, the judgments were improved with the use of visual aids regardless of cognitive traits. These results show that while not all visual aids enhance understanding of food safety information, appropriately designed visual aids do, and that cognitive traits producing individual differences in judgments on food safety should be taken into account when considering how food safety information should be conveyed.
