Abstract
Previous research has demonstrated that auditory and visual stimuli have individual effects on the accuracy of a person’s estimation of time-to-contact (TTC), the time at which two objects collide. Prior findings also suggest that there is cross-modal interference between vision and audition; however, this phenomenon has never been studied in a TTC situation. (Driver & Spence, 1998; Ichikawa & Masskura, 2006; Roseboom, Kawabe, & Nishida, 2013) In this study we attempted to fill in this research gap by examining the effect of auditory speed cues over visual speed cues in a two-dimensional TTC scenario, and by determining if an object’s temporal presence influences accurate perception of TTC by using occlusion. Our results indicate that in the presence of auditory and visual speed disparity, participants rely more heavily on auditory cues, but when auditory and visual speeds are equivalent, or when there is no audition present, participants rely more on visual cues.
