Abstract
|
|
|
Objective : The purpose of this study was to investigate the effect of hand tapping on the accuracy and the fluency of speech production in children with speech sound disorder(SSD) and their typically developing peers(TD).
Methods : The study subjects were 15 SSD children and 15 TD children aged 4, 5, and 6 years of age. Subjects were asked to give a picture name without hand tapping in the first experimental condition, and with hand tapping in the second experiment condition.
Results : The results showed that hand tapping significantly increased disfluency in TD, whereas in SSD. it did not affect the accuracy or fluency of speech production. In addition, TD demonstrated a significant positive correlation with the changes of accuracy and disfluency due to hand tapping, whereas SSD had no correlation.
Conclusion : We discussed the possibility that hand tapping could serve as an obstacle distracting attention from SSD and TD, acting as a motor gesture to facilitate phonological processing when facing the difficulty in lexical retrieval for SSD.
