Disfluencies in the reading of 60 normal college subjects were studied in three experimental conditions: Contingent “Right”, Contingent “Buzzer”, and Contingent “Wrong”. Ten High and 10 Low disfluency level subjects participated in each condition. The subjects read consecutively for 36 minutes. The first and last 12 minutes were Baserate Segments, during which no experimental manipulations were introduced. During Segment 2 (the middle 12 minutes), subjects were presented with a buzzer or with the words “Right” or “Wrong” immediately after each repetition or hesitation emitted as they read. Subjects in the “Wrong” condition showed a clear punishment effect, with a significant decrease in disfluencies between Segments 1 and 2, and a significant increase in disfluencies again in Segment 3. Data for the other conditions were more equivocal. Instructions to one group of subjects to decrease disfluencies resulted in a marked attenuation of the response, even though no contingencies were arranged.
