Interactions between auditory representations of musical pitch and pitch coding

认知干扰的实验采用与音高一致和不一致的音节进行。音乐音高识别任务的性能受到干扰不一致的音高标签。特别是，绝对音高的参与者受到音高处理时阴影音节，并表现出退化的性能在音节任务。一项关于绝对音高的大规模测试显示，日本音乐学生中绝对音高的普遍性比以往任何时候都要高。

Experiments on cognitive interference were carried out using vocal stimuli sung with syllables congruent and incongruent with their pitches. Performance of the musical pitch identification task was interfered by incongruent pitch labels. In particular, participants with absolute pitch were influenced by pitch processing when shadowing syllables and showed a degraded performance in the syllable task. A large-scale test on absolute pitch revealed that prevalence of absolute pitch is much higher than ever believed in Japanese music students.
