Abstract: The present study examined the effects of spatial sound-source density and reverberation on the spatiotemporal window for audio-visual motion coherence. Three different acoustic stimuli were generated in Virtual Auditory Space: two acoustically “dry” stimuli via the measurement of anechoic head-related impulse responses recorded at either 1° or 5° spatial intervals (experiment 1), and a reverberant stimulus rendered from binaural room impulse responses recorded at 5° intervals in situ in order to capture reverberant acoustics in addition to head-related cues (experiment 2). A moving visual stimulus with invariant localization cues was generated by sequentially activating LED’s along the same radial path as the virtual auditory motion. Stimuli were presented at 25°/s, 50°/s and 100°/s with a random spatiotemporal offset between audition and vision. In a 2AFC task, subjects made a judgment of the leading modality (auditory or visual). No significant differences were observed in the spatiotemporal threshold (PSE) or the slope of psychometric functions (β) between all three acoustic conditions. Additionally, β was spatially invariant across velocity, suggesting a fixed spatial audio-visual integration window. Findings also suggest a key role for auditory de-reverberation in processing moving auditory stimuli and establish a perceptual measure for assessing the veracity of motion generated from finite and discreet locations.
