Some Factors That Influence Pure Tone Delayed Auditory Feedback

Abstract

Some of the major factors that might influence tapping changes induced by relatively short-term, pure tone delayed auditory feedback (DAF) were investigated. Stimulus frequency, subject, sex, sophistication, practice, physical fatigue, adaption to the task, and habituation to the task were considered. Only sophistication and habituation influenced performance significantly. The introduction of pure tone DAF within 5 dB SL, produced observable changes in tapping, thereby providing a sensitive means of extrapolating pure tone thresholds in a relatively objective manner.
