Abstract: | Speech sounds are judged reliably and absolutely, while the judgment of nonspeech stimuli, such as tones, is thought to be unreliable and dependent on contextual cues. Here we demonstrated that the judgment of tonal stimuli may also be reliable and absolute, provided that the subjects are trained musicians. In Experiment 1, musicians with relative pitch identified 21 tonal intervals ranging from unison to major third, and the resulting identification functions were similar to those that have been previously obtained for speech. In Experiment 3, the judgment of intervals by musicians was shown to be free of context effects, since the best subjects gave virtually identical judgments to the same intervals in two stimulus contexts. Similar results were obtained in Experiments 2 and 4 for the judgment of single tones by possessors of absolute pitch. Performance with both notes and intervals by nonmusicians, however, was unreliable and greatly influenced by context. These findings suggest that musicians acquire categories for pitch that are functionally similar to phonemic categories for speech |
