Abstract
The purpose of this study is to test the hypothesis that during audiovisual message processing (e.g., television or film), cuts in the video track cause an orienting response, which is reflected in the involuntary shift of attention. In classic research by CitationReeves et al. (1985), changes in the alpha band were noticed in reaction to montage cuts. We propose an investigation of the brain's reaction to montage cuts by means of event-related potentials (ERPs), which are the brain's electrophysiological responses to a stimulus. Well-known indices of orienting response are two ERP components: P3 and slow cortical potential (SCP). Ten participants watched a film consisting of 105 related and 114 unrelated cuts while an electroencephalographic signal was recorded. The hypothesis that unrelated cuts in the video track when watching an audiovisual message cause more pronounced SCP was confirmed. There was no effect of unrelated cuts on P3. The results of this study provide a good starting point for further research on brain reactions to the structural features of an audiovisual message, such as close ups or camera moves.
