摘要：

The audio-visual link in auditory spatial discrimination was analyzed. Perceptual effects were examined from decision/motor effects by two means. Firstly, spatial discrimination performance were measured. Secondly, the signal detection theory was used to separate perceptual senstivity from the decision bias. The experiment shows that the discrimination becomes better as stimulus onset asynchrony (SOA) was increased.
