In considering capacity measures of audiovisual integration, it has become apparent that there is a wide degree of variation both within (based on unimodal and multimodal stimulus characteristics) and between participants. Recent work has discussed performance on a number of cognitive tasks that can form a regression model accounting for nearly a quarter of the variation in audiovisual integration capacity. The current study involves an investigation of whether different elements of musicality in participants can contribute to additional variation in capacity. Participants were presented with a series of rapidly changing visual displays and asked to note which elements of that display changed in synchrony with a tone. Results were fitted to a previously used model to establish capacity estimates, and these estimates were included in correlational analyses with musical training, musical perceptual abilities, and active engagement in music. We found that audiovisual integration capacity was positively correlated with amount of musical training, and that this correlation was statistically significant under the most difficult perceptual conditions. Results are discussed in the context of the boosting of perceptual abilities due to musical training, even under conditions that have been previously found to be overly demanding for participants.
