Pictorials can aid in communicating warning information, but viewers may not always correctly comprehend them. Two experiments focused on whether the use of relevant highlighting could benefit pictorial comprehension. A set of warning-related pictorials were manipulated according to three-color highlighting conditions: highlighting areas more relevant to correct comprehension, highlighting areas less relevant to comprehension, and no highlighting. Participants were asked to describe the purpose and meaning of each pictorial presented to them. The findings from both experiments indicate that comprehension of warning pictorials is higher for the relevant highlighting condition than the other two conditions. The highlighting of less relevant areas reduced comprehension compared to no highlighting. Use of appropriately placed highlighting could benefit the design of a complex symbol by pointing out pertinent areas to aid in determining its intended conceptual meaning.
图片有助于传达警告信息，但观众可能并不总是能正确理解它们。两项实验聚焦于使用相关突出显示是否有助于图片理解。一组与警告相关的图片根据三种颜色突出显示条件进行了处理：突出显示与正确理解更相关的区域、突出显示与理解不太相关的区域以及不进行突出显示。要求参与者描述展示给他们的每幅图片的目的和含义。两项实验的结果均表明，与其他两种条件相比，相关突出显示条件下对警告图片的理解更高。与不进行突出显示相比，突出显示不太相关的区域会降低理解。通过指出相关区域以帮助确定其预期概念含义，使用适当放置的突出显示可能有利于复杂符号的设计。
