The core disruption under delayed auditory feedback: evidence from adaptation study

The present study investigated the course of adaptation of various disfluency types during five repeated oral readings under bilateral delayed auditory feedback. The results indicate that, contrary to earlier findings, a significant adaptation of disfluencies occurs during repeated oral readings under DAF. Frequency of dysrhythmic phonations and reading errors decreased significantly in successive readings whereas the frequency of part-word repetitions showed no such decrease. It is suggested that, of the many different forms of disruptions known to occur under DAF, part-word repetitions represent the most basic and persistent form of disruption.
