This episode features Christopher Constantino, Ph.D., CCC-SLP as he explores the novel construct of spontaneity of speech as it applies to stuttering. This discussion outlines a theoretical model that emphasizes spontaneity rather than fluency to understand the experience of stuttering. It reviews the results of an ecological momentary assessment study in which spontaneity and fluency are measured during the real-life conversations of people who stutter and modeled over time. Clinical implications are discussed.
