ABSTRACT
Temporal aspects of dynamic sound localization were examined in four experiments. Motion was simulated by dynamically changing the interaural delay of a train of high-frequency-filtered, Gaussian clicks. Determining the direction of motion could not be explained by a model that relies entirely on the onset-offset positions of the moving stimulus. The data suggest a lowpass filtering of interaural delay information with a time constant esti mated at 60-130 ms. Results from discrimination and descriptive studies of motion are compared.
