This paper describes two types of auditory aftereffects concerning sound localization. The first type involves the shifts in apparent location of a test sound with a given interaural time difference (ITD) following presentation of an adapting sound having a different ITD. The second type involves changes in ITD discrimination thresholds following adaptation. The aftereffects can be simulated by the interaural cross-correlation model with gain control. These results are consistent with the idea that the gain of ITD-selective units, located after binaural interaction but before across-frequency integration, changes according to recent input.
