Brief summary
The goal of this study is to understand what people understand from medical illustrations, and what meaning and emotions (such as anxiety) they derive from different design elements.
Detailed description
The investigators will conduct cognitive interviews to understand the meaning laypersons obtain from different illustrations, their opinions on illustration styles, and their level of anxiety after viewing illustrations. The investigators will also study the effect of systematically varying medical illustration designs on layperson understanding and anxiety.
