When we read literature, we often become immersed and dive into fictional worlds. The way we perceive those worlds is the result of skillful arrangement of linguistic features by story writers in order to create certain mental representations in the reader. Narrative perspective, or focalization, is an important tool for storywriters to manipulate reader's perception of a story. Despite the fact that narrative perspective is generally considered a fundamental element in narrative comprehension, the cognitive effects on story reading remain unclear. In previous research, various methodologies were employed to investigate the cognitive processes underlying narrative comprehension. However, studies used either self-report procedures or behavioral tests to investigate reader's reactions and refrained from combined methodologies. In the present study we combined skin conductance measurements and questionnaires while participants read short stories in 1st and 3rd person perspective. The results show that immersion, imagery and appreciation are higher when participants read stories in 1st person perspective. To our surprise, we found higher arousal for reading 3rd person perspective compared to 1st person perspective narratives. We find evidence, that individual difference in arousal between the two conditions is related to how much readers empathize with the fictional characters. The combination of methodologies allows us a more differentiated understanding of the underlying mechanisms of immersion. In my talk, I want to highlight how we can gain more from interdisciplinary research and combinations from various methodologies to investigate cognitive processes underlying narrative comprehension under natural conditions.
