The Influence of Narrative Structure on Story Map Engagement, Performance, & Trust: A Preliminary Study
This empirical map study evaluated how narrative structure affects user engagement, performance, and trust by testing 135 participants recruited via Prolific. Using a custom-built 'Story' module in the MapStudy framework, the researchers compared two variations of the 'martini glass' narrative structure: placing an interactive map at the beginning (reverse martini glass) versus at the end of a linear, scroll-based story. The experiment utilized two environmental hazard stories—one on Hurricane Harvey in Texas and another on the Tubbs Fire in California—and tracked element-level viewing times and map interactions.
Why it matters — It provides a framework and empirical baseline for testing how the sequencing of author-driven scrollytelling and reader-driven map exploration influences how audiences comprehend and trust spatial narratives.
Caveat: The study is presented as a preliminary investigation with a relatively small sample size of 135 participants split across three geographic groups.
