Traditional psychophysical studies have been primarily unimodal experiments due to the ease in which a single sense can be isolated in a laboratory setting. This study, however, presents participants with auditory and visual stimuli to better understand the interaction of the two senses in visuospatial perception. Visual stimuli, presented as Gaussian distributed blobs, moved laterally across a computer monitor to a central location and "bounced" back to their starting position. During this passage across the screen, a brief auditory "click" was presented via headphones. Participants were asked to respond to the bounce of the ball, and response latency was recorded. Response latency to the bounce position varied as a function of baseline (no sound) and the varying sound offset locations.
