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.
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.

Transcripts from 100 cognitive interviews, and quantitative measures of comprehension and anxiety from 7,600 participant reactions to patient education documents will be generated. We will create de-identified data sets of all quantitative human subjects data that will be preserved and shared. The purpose for creating this is to allow other investigators access to the data to both validate our findings and to further advance inquiry in the field.
Prior to end of the study.
Sharing of de-identified human subjects data will be consistent with HIPAA guidelines and the Final NIH Statement on Sharing Research Data. We do not anticipate any limitations on sharing.
