Real-world match	2	Survey section numbering, sequence, and naming were logical and consistent with real world conventions Survey questions follow conventions for type and format Embedded YouTube videos take advantage of familiar features, platform	Procedure for leaving and returning was not conventional or natural “Survey” terms in standardized research questionnaires did not match real-world conventions Additional section links are hard to find, and function in unconventional and nonnatural ways
3. User control	2	Reset function was an effective undo feature	“Emergency exits” were unclear in additional help sections
