This study examines the relationship between an individual's performance on auditory event-related potential (AERP) measures and the individual's response to an altered auditory feedback device (AAF). Auditory ERP measures were obtained in a oddball P300 paradigm using simple linguistic stimuli for 20 stutterers, 10 who demonstrated a positive response to AAF, and 10 who did not appear to benefit from AAF. Results are discussed in terms of the relationship between auditory AERP latency and amplitude distribution patterns and AAF response.
