Several stimuli were made contingent on the speech disfluencies of normal adult speakers. The first four subjects were unselected volunteers. For three of them, response-contingent presentation of a tone, a light, or the words right or wrong had no effect on disluency rate. When the contingency was pointed out to these subjects through instructions, however, presentation of the stimuli was then followed by substantial reductions in disfluencies. The fourth subject spontaneously solved the contingency and showed reductions even before instructions were given.

Two additional subjects were selected from a speech pathology class and could, therefore, be expected to be more concerned about speech from the outset. They were presented the light contingent on disfluencies without any instructions and showed response reductions.
