Lateralization Of Simulated Sources And Echoes On The Basis Of Interaural Differences Of Level, Raymond H. Dye Jr, Jacquelyn P. Hill, Leslie M. Ryan, Alexander E. Cupler, Kevin M. Bannon

Raymond Dye

This experiment assessed the relative weights given to source and echo pulses lateralized on the basis of interaural differences of level (IDLs). Separate conditions were run in which the to-be-judged target was the first (source) or second (echo) pulse. Each trial consisted of two intervals; the first presented a 3000-Hz diotic pulse that marked the intracranial midline and the pitch of the target frequency. The second presented the sequence of a source followed by an echo. Target frequency was always 3000 Hz, while the non-target pulse was presented at 1500, 3000, or 5000 Hz. Delays between the source and echo …
