Lateral position of dichotic pitches can be substantially affected by interaural intensitive differences

Using an acoustic pointer, three listeners matched the intracranial position of dichotic pitches presented with interaural intensitive differences (IIDs). Unlike data previously reported [Raatgever, ‘‘Binaural time processing and time-intensity trading,’’ in Psychophysics, Physiology, and Behavioural Studies in Hearing, edited by G. van den Brink and F. A. Bilsen (Delft U.P., Delft, The Netherlands, 1980), pp. 425–453], the intracranial position of the dichotic pitch image was moved substantially by IIDs. When the dichotic stimuli were presented continuously and turned off only when the listeners used the acoustic pointer, one listener produced data like those previously reported by Raatgever. Consequently, in terms of lateralization, it does not appear necessary to maintain a theoretical cleavage between images produced by dichotic pitches (previously thought to be influenced only by ITDs) and images produced by other binaural stimuli.
