UD Assistant Professor Evan Usler says that stuttering, a motor speech and fluency disorder, can persist from childhood to adulthood when individuals who stutter try to compensate for the anxiety they feel when speaking by avoiding words they think they can't say. Ulser, who runs the Interpersonal Neurophysiology Lab at UD, advocates "stutter[ing] openly and confidently, as it is often then that fluency seems to emerge."
