Abstract

Visual bias is a psychophysical phenomenon where an accurately localized irrelevant signal, such as a light, will bias a spatially discrepant target that is localized with less accuracy, such as a sound, when the two stimuli are perceived as unified. Many previous studies have demonstrated visual bias in azimuth, but none have tested directly, or found, this effect in depth. The current study was able to produce over 90% bias in azimuth and somewhat less (83%) bias in depth. Bias can be predicted by the variance of the localization of each unimodal signal in each unimodal signal in each direction in space, as predicted by a maximum likelihood estimate.
