Theories re: Etiology. h Neurophysiologic Laryngeal Dysfunction – excessive tension, irregular vibrations (part of stuttering, but not the cause) Faulty Brain Function/Structures - slower speech movements in people who stutter (still not the cause) Defective Auditory Mechanism h Stuttering decreases h When hearing is masked by noise fed to ears through earphones h In the delayed auditory feedback (hearing one’s speech after a slight delay). However, DAF results in slower
