Inter-subject correlations in heart rate. ISCHR is calculated as the correlations in heart rate between each pair of participants. An average is taken for each participant to determine how synchronous they are with other participants. Top: Relationship between narrative engagement and ISCHR for each condition. Error bars denote 95% confidence intervals within each clip. Bottom: Individual correlations between ISCHR, narrative engagement, and immersion. Each point represents one participant. Boxplots denote median and quartiles, violin plots provide density estimates
