The Department of Psychology's public lecture by Jonathan Wilbilks, candidate for a tenure-track position in Psychology, on 'Investigating the Dynamic Capacity of Audiovisual Integration" will take place on Thursday, April 12 at 9 a.m. in  Hazen Hall, 232.


The capacities of unimodal processes such as visual and auditory working memory, multiple object tracking, and attention have been heavily researched in the psychological science literature. In recent years there has been an increase in the amount of research into multimodal processes such as the integration of auditory and visual stimuli, but relatively little work investigating the capacity of audiovisual integration.  This talk will present a series of experiments elucidating the factors that contribute to the capacity of audiovisual integration, and illustrating that the interaction of these respective factors makes capacity a fluid, dynamic property.  I show that capacity modulates based on factors such as proactive interference, temporal predictability, crossmodal congruency, perceptual chunking, and training.  Having established the factors that contribute to capacity, I will present work towards building a predictive model of audiovisual integration capacity based on individual differences in unimodal processes such as multiple object tracking and visuospatial working memory span.

This research extends what is known about audiovisual integration capacity, both in terms of its numerical value and the factors that play a role in its establishment. It also demonstrates that there is no overarching limitation on the capacity of audiovisual integration, but rather that it is a process subject to multiple factors, which can be changed depending on the situation in which integration is occurring.
