Objectives: The main purpose of this study was to compare the competence of phonological short-term memory and foreign language vocabulary learning between children with speech sound disorders (SSD) and their typically developing (TD) peers. In addition, this study tried to investigate the relationship among phonological short-term memory, other variables such as nonverbal intelligence and vocabulary knowledge, and foreign language word learning.
Methods: The study subjects were 20 SSD children and 20 TD peers from 4 to 5 years of age. For this study, nonverbal intelligence, native (Korean) vocabulary knowledge, foreign (English) vocabulary knowledge, nonword repetition scores and English vocabulary learning scores were collected.
Results: SSD children had lower scores in nonword repetition task and English vocabulary learning task than TD children. Also, nonword repetition ability was strongly influenced by percentage of correct consonants. And the receptive English vocabulary learning score was influenced by nonword repetition score whereas expressive English vocabulary learning score closely linked to English vocabulary knowledge.
Conclusion: The findings suggest children with pure SSD are expected to have more trouble in learning English vocabulary because of low phonological short term memory. Thus, it is important to improve phonological short-term memory for successful English learning, and this can also be accomplished by increasing English vocabulary knowledge.
