VISUAL LOCALIZATION ACCURACY DETERMINES THE BIAS OF AUDITORY TARGETS IN AZIMUTH AND DEPTH

abstract

Visual bias is a psychophysical phenomenon where an accurately localized signal, such as a light, will bias a spatially discrepant signal that is localized with less accuracy, such as a sound, when the two signals are perceived as unified. Many previous studies have demonstrated visual bias in azimuth, but none have directly tested, or found, this effect in depth. By increasing the saliency of the auditory and visual signals from a previous experiment, the current study was able to produce more accurate depth discrimination. Visual localization error was smaller than that of auditory localization error in both azimuth and depth, and visual bias was demonstrated in both dimensions. Additionally, visual localization accuracy was positively correlated to visual bias on perceived unified trials.
