Kwei Tan's training experiment took thirteen advanced students through repeated intensity-of-sound discrimination measurements; six continued for twenty hour-periods each and six for thirteen to seventeen periods. The article reports "no evidence of improvement with -practice" despite individual fluctuations in the practice course.
