Preference AssessmentsType (MSWO, paired-choice)Format (tangible, pictorial)Physical (reach, vision)

Compared Tangible and Pictorial Formats

Results: 5/7 did not show consistent preferences across the two formats

Conclusion: preference assessments are affected by presentation format

Compared choice formats to engagementPictorial, Tangible, Verbal, Textual

Results: tangible and verbal were predictive of engagement
