Results from Experiment 1: Visual capture is apparent when subjects localized the auditory component of AV trains (A within AV) and the ventriloquism aftereffect is apparent when subjects localized the second auditory target presented after AV trains (A2 after AV). a, Auditory localization response errors from a representative subject are shown over a range of delays and azimuths with respect to the auditory component of AV disparity trains. Auditory spatial perception is predominantly shifted in the direction of the visual target, as demonstrated by the direction and magnitude of localization errors when the visual target was right (+8°) or left (−8°) of the auditory target. b, Visual capture is larger than the ventriloquism aftereffect, which dissipates over time and is no longer significant after 20 s. Colors represent individual subjects, while black indicates group means. c, The ventriloquism aftereffect on average extends to local space by at least 15°. Points represent auditory shift for A2 positions (1 s delay), all relative to the auditory component of AV disparity trains. Data at 0° azimuth are the same as the 1 s point in b.
