image: Image Captions: a: Tonic pupil size as a function of video condition, spouse condition, and relationship quality. Note. Graph shows pupil size in millimeters across all video clips from videos’ onset to videos’ end. The lines depict the average linear change for all participants and for all video clips as reported in Table 4. Circles and triangles represent the raw data in 100ms bins. b: Average tonic pupil change by condition: Three-way interaction. Note. This graph depicts the amount of increase in pupil size by condition when viewing the horror videos compared to pupil size during neutral videos. Having a supportive marital relationship while concurrently having one’s spouse hold their hand resulted in less pupil dilation during horror videos. Graph depicts the same data as Fig 2a but modeled as change scores to represent more clearly this statistically significant three-way interaction. view more
