Abstract
Measurements of perceived lateral distance were made using transients in a lateralization paradigm. Two binaural clicks (referred to as boundary clicks) presented with interaural differences of time (IDT) were used to indicate a lateral “distance” along the interaural axis. IDT for the first click was zero (diotic) and for the second, a fixed and predetermined value (dichotic). The location of an additional click (pointer click) was controlled by the subjects, who were instructed to bisect the perceived lateral distance between the two boundary clicks with this pointer click. The procedure was repeated for three distances. Results indicate a linear relation between judgments of distance and changes in IDT (r2 = 0.999).
