Abstract
ABSTRACT Looming objects generate unique multisensory information and can signal potential danger. While visual judgments of arrival time are relatively accurate, auditory judgments tend to be anticipatory. When presented with information from both modalities, observers tend to rely on visual information for successful interaction. Previous work has shown that auditory information can influence perception of visual looming and receding. Here, we examined how visual information affects the auditory perception of looming and receding sounds. Participants judged the loudness change of sounds accompanied by visual looming and receding stimuli. We found that looming and receding visual stimuli influenced estimates of loudness change. Sounds were perceived to change more in loudness when presented with a larger visual change. We also found that looming sounds were perceived to change more in loudness than equivalent receding sounds and that participants showed better discrimination of the change between receding sounds than looming sounds.
