title: Adaptation of residue pitch.
abstract: Residue pitch was examined by means of adaptation. The monaural perceptibility of a residue pitch was measured before and after exposure to ipsilateral or contralateral adapatation stimuli of variable spectral composition. Several aspects of adaptation were investigated: pitch channel specificity, number of stimulus components necessary to adapt a residue channel, importance of temporal and spectral factors for adaptation, and the relation between pure-tone and residue pitch. It was found that there are residue-pitch channels specifically sensitive to the spectral region and ear of presentation of the stimulus. At least two harmonics were necessary to adapt a residue channel, and pitch channels were found to be insensitive to temporal factors. Residue and pure-tone pitch seemed to be extracted by different mechanisms, having independent channels. The data presented augment the understanding of pitch perception and suggest refinements for pitch-perception models.
