title: An experimental increase in stuttering frequency.
abstract: The purpose of the present experiment was to investigate whether stuttering frequency could be increased from baseline by an experimental condition. Initially, 10 adult stutterers spoke spontaneously while alone. Next, they continued speaking, but with an adult, male conversationalist. Finally, the subjects again spoke while alone. Percent stuttering increased in the conversational situation compared with the baseline (alone) situation, and decreased in the final baseline (alone) situation compared with the conversational situation.
