Synchronous brain waves reflect differences in attention modulated by personal trait
conference paper
Presentation of identical stimuli to multiple observers can result in inter-subject correlations in the electroencephalogram (ISC-EEG). ISC-EEG has been associated with attention, but it is unclear if ISC-EEG can capture differences in attention that arise due to differences in personal traits across individuals causing differences in relevance of the presented stimulus. In this study, we investigate whether ISC-EEG differs between observers with different levels of food neophobia when watching a 15-minute movie about food. As hypothesized, we found a significant correlation between food neophobia and ISC-EEG. We also found a significant correlation between ISC-EEG during the movie and event-related potential (ERP) amplitude toward food images, a more traditional measure of attention.
