Title: Impact of Action-Object Congruency on the Integration of Auditory and Visual Stimuli in Extended Reality

 

Abstract: Understanding how humans integrate stimuli from different modalities into crossmodal objects is important for the development of effective extended reality (XR) systems. Through the process of multisensory integration, information from different sensory modalities is used to determine whether stimuli should be bound together into a unified percept. In XR environments, basic congruency of time and space may be insufficient. As such, the proposed research will investigate a new type of crossmodal congruency, called action-object congruency. Research in ecological sound perception has identified various action and object features of sound-producing events that humans can discern. As a result of multisensory perceptual learning processes, this information could be used to inform the integration of auditory and visual stimuli, even when those stimuli are novel. In the proposed research, temporal and spatial ventriloquism illusions will be utilized to assess the impact of action-object congruency. Within a virtual environment, participants will view objects interacting and hear sounds presented either from a slightly different location or with a slight delay. Participants will localize the sounds via pointing, or judge whether the auditory and visual events were simultaneous. Action and object congruency of stimuli will be manipulated. It is expected that action-object congruent visual and auditory pairings will lead to greater localization bias and higher rates of perceived simultaneity.
