Abstract: Objective To investigate the etiology and pathology of functional articulation disorder (FAD) by minimal phoneme contrast test in children with FAD. Methoods One hundred FAD children and one hundred typical children matched for ages were selected as testees.The auditory recognition abilities were examined by Minimal Phoneme Recognition Scale in a quiet room.Intelligence and language developments were evaluated in test groups. Results The recognition abilities of Consonant Phoneme Contrast (CPC),Vowel Phoneme Contrast (VPC) and the subtests in FAD children were all much inferior to typical children (P<0.05).There was a negative correlation between the recognition abilities of all tests and impairments in FAD children,except the type of CPC described as "the same manner with different places",the VPC of retroflex and unretroflex and the VPC of front nasal and back nasal; Except the CPC of fricatve and unfricative (P>0.05),the recognition abilities of CPC,VPC and the other subtests in FAD with language impairment (n=36) were all much inferior to FAD (n=64) (P<0.05).Twenty-nine patients were moderate to severe disorder in FAD with language impairment (80.56%). Conclusion The recognition abilities of Phoneme Contrast (PC) in FAD children are much inferior to typical children,which might contribute to FAD.
