Exploring the Effects of Editing Techniques via Event-related Potential

Abstract

In this study, we explored the neural correlates of the movie-viewing experience. Previous studies have shown that shot changes in a video consistently elicited event-related potential (ERP) components associated with semantic disruptions such as the N400 and P600 component, and we attempted to replicate the findings under a naturalistic viewing experience by showing the participants a feature film. Additionally, we also explored how the ERP components interacted with the various continuous editing techniques in the movie. Consistent with prior research, we found that shot changes in a movie reliably elicited distinct ERPs, characterized by a negative frontal deflection (N400) and a positive posterior deflection (P600). The amplitude of these components, however, did not differ significantly across different editing techniques, or during the start and the end of the movie. Notably, we found a significant right-lateralization of the posterior component, and this effect was weaker in ERPs elicited by match on action cuts, and right-to-left shot/reverse shots. We tested if the posterior lateralization was elicited by detection in bilateral spatial changes and received nonsignificant effects. Finally, we discussed the implications of the results, and potential connection between the posterior lateralization and spatial perception during shot changes.
