Abstract

The encoding of space between the visual and auditory systems does not always align. For foveal species like humans and monkeys, the visual field is restricted to frontal space, whereas the auditory field is panoramic, covering the entire surrounding space. Sensitivity to sounds coming from the rear brought by spatial hearing is critical for avoiding unseen dangers. Our recent study shows that, in humans, vision's influence on auditory perception can extend to unseen rear space (Montagne and Zhou, 2018). The present study further investigates the effects of visual stimulation on reaction times when listeners localize an auditory target presented from the front or rear. Experiments are designed to survey two types of reaction times simultaneously: (1) choice reaction time for pushing a button to indicate the perceived front or back location of a sound; (2) saccade reaction time by listeners shifting their gaze to indicate the lateral direction of a perceived sound source. Our results show domain-specific effects of visual capture on both types of reaction times, and support our previous findings that audio-visual interactions are not limited by the spatial rule of proximity.
