Reading fiction can be a profoundly moving experience, and emotions are an important explanatory factor when it comes to fiction’s psychological impact on the reader. Emotions arise when events of the story relates to the reader’s wishes and concerns (Oatley, 1999), and they have the ability to direct attention, prompting readers to focus on specific issues (Vuilleumier, 2005). What remains less clear, is how the overall reading experience is affected by the dynamic interplay of emotions throughout the narrative. This thesis undertakes one aspect of emotional responses to fiction reading, namely the effect “built-up” tension has on the experience of being moved (feeling kama muta) by a narrative. The main question raised in this thesis is whether antecedent tension can lead to a stronger kama muta experience. To investigate this topic, I conducted an online survey, consisting of short stories preselected to evoke kama muta, along with questions about felt emotions and probability evaluations of the story’s outcome. A tension scale was also developed, consisting of nine items, based on the general model of tension presented by Lehne and Koelsch (2015). Participants were selected through an online snowball sample, as well as through Clickworker.com. When partaking in the survey, participants were first tasked with reading the first half of a randomly selected short story. They were then asked about felt tension, their desired story outcome and probability estimates of said desire. Participants then proceeded to the second story half, before finally rating their kama muta experience, as well as whether the ending corresponded to their hopes and were emotionally satisfying. They also rated other felt emotions, and whether they were familiar with the story outcome form before. Results showed that tension strongly predicted kama muta intensity; participants who felt more tension while reading, also felt more kama muta. Moreover, a strong desire for a specific story outcome further predicted tension. This was supported by a mediation analysis of desirability of outcome and kama muta, with tension as the mediating variable. A full mediation effect emerged, indicating that tension fully accounted for the effect desirability of outcome had on kama muta. Tension also correlated with other emotions, suggesting that felt tension increases emotional intensity, regardless of the quality of the emotional response. This thesis is part of the larger research work done on kama muta at the University of Oslo, and data was collected independently by the author.
