The present study was to further the understanding of the conceptual relationship between narrative absorption, that is the intense engagement with a story world, and felt suspense, that is the anticipation of a narrative outcome event. To this end, a media comparative online experiment was conducted with a 2 (Media format: film vs. Literature) × 2 (Suspense structure: diegetic vs. Non-diegetic delay) × 2 (Stories) between subject design. Results revealed a complex relationship among felt suspense, attention, emotional engagement, and transportation, showing the high importance of attention in felt suspense, and the moderating effect of media format and gender. Findings indicate that non-diegetic suspense delay unlike diegetic suspense decreases felt suspense and narrative absorption independently of media format.
