The “rhythm effect” in stuttering as a function of predictability of utterance

Eighteen adult male stutterers read aloud words shown on a screen at a given signal. Ten different time intervals between word presentation and signal to read were used under each of the two experimental conditions. In Condition 1 (prediction), the signal to speak coincided with the time at which a...

Summary:Eighteen adult male stutterers read aloud words shown on a screen at a given signal. Ten different time intervals between word presentation and signal to read were used under each of the two experimental conditions. In Condition 1 (prediction), the signal to speak coincided with the time at which a rising white column came into contact with a horizontal bar across its path. In Condition 2 (non-prediction), the horizontal bar was absent and the subject was not able to predict when the signal to speak would occur. Each subject served as his own control. The opportunity to predict when to speak reduced the time needed to complete the utterance but not the total number of speech errors. The variance due to subjects was very large in both cases.
