A Neuroscience Perspective
on Stuttering
Stuttering afflicts one percent of the world’s adult
population. A ten-year- old child who stutters might
be terrified to speak in front of his class, yet is
fluent when singing, despite similar embarrassment.
Stutterers are fluent when singing. This disrupted speech
motor output of stuttering is not random and probably
reflects disturbance in auditory feedback. An improved
understanding of this disruption in speech (motor) output
would improve our understanding of language processing.
Dr. Rosenfield presented current research, including
an animal model of stuttering. This model focuses on
phonotory iterations in Zebra finches and provides insight
into this disorder.
