Abstract：OBJECTIVE: To investigate the central auditory processing function in children with functional articulation disorders (FAD), and possible causes of FAD. METODS: Twenty-seven children with FAD were selected as the case group and 50 age-matched normal children were selected as the control group. The two groups were compared with respect to the following factors: percentage of individuals with a positive history of language development disorder, and the form, peak latency and peak amplitude of mismatch negativity (MMN) on auditory event-related potentials. RESULTS: Compared with the control group, the case group had a significantly higher percentage of individuals with a positive history of language development disorder (70% vs 8%; P0.05). CONCLUSIONS: Prolonged central auditory processing may be one of the causes of FAD in children.
