Abstract

The lateral position of pulsed sinusoids presented with interaural intensive or temporal differences was determined for a variety of frequencies, overall intensities, and durations. The lateral position of stimuli presented with interaural temporal differences was linearly related to interaural phase for interaural phases between 0° and ±90°. Beyond ±90° the images often appeared at more than one position, usually on opposite sides of the head. The lateral position of stimuli presented with interaural intensive differences was linearly related to interaural intensity up to ±15 dB. These results were largely unaffected by frequency, duration, and overall intensity, although some of the small dependencies are described and discussed. The results are consistent with the assumption that lateral position at any one frequency is determined by mechanisms similar to coincidence networks or cross correlators. However, a single cross-correlation mechanism cannot account for the results obtained across frequency.
