title: Aftereffect arising from unidirectional change of sound level in a tone: frequency specificity with a complex adaptor.
abstract: Subjects adapted to square-wave adaptors, stimuli containing odd harmonics of the fundamental, and, to provide baseline data, sinusoidal adaptors matching the square-wave's fundamental. Nulls were obtained for various frequencies of the test stimulus. At any given frequency, the baseline null was subtracted from the null for square-wave adaptation. These corrected nulls indicated frequency-specific aftereffects at the third and fifth harmonics. The evidence is consistent with previous attempts to link the aftereffect of changing sound level in a tone with the auditory movement aftereffect because the latter may also show frequency specificity.
