Özet

Objective: Stuttering is a speech disorder, where speech fluency is disturbed by the involuntary repetition and prolongation of words and syllables. Its cause is not fully known. Sensory gating is an essential part of information processing and developing an appropriate behavioral response in the brain. Psychological, social, and learning-related factors together with sensorymotor variables play an important role in ensuring fluent speech. Sensory gating protects the brain from overload by filtering the redundant or potentially irrelevant information from the continuous and intensive stream of information. A lack of sensory gating for auditory stimuli may lead to disturbed auditory signal processing and auditory feedback and result in loss of speech fluency. Our aim in this study was to evaluate the state of sensory gating in children and adolescents with developmental stuttering using P50 suppression to test our hypothesis that sensory gating may be disturbed in stuttering.
