Abstract

Objectives: This study aims to investigate developmental patterns of nonword repetition scores in 3- to 5-year-old typically developing children and examine whether and to what extent nonword repetition scores are related to age, vocabulary and articulatory skills.
Methods: A total of 141 children (3-year age group, 37; 4-year age group, 52; 5-year age group, 52) participated in this study. Nonword repetition, articulation, and receptive and expressive vocabulary tests were administrated. Nonword repetition scores, word length and phoneme scores of the word test from Children Articulation and Phonology Profile, percentage of consonants correct from the Assessment of Phonology and Articulation for Children, and raw scores from Receptive & Expressive Vocabulary Test (REVT) were obtained.
Results: Five-year-old children showed significantly higher nonword repetition scores than 3- and 4-year-old children. No significant difference existed between 3- and 4-year-old children. The results showed that nonword repetition scores were positively related to word length and phoneme scores of the word test and the raw scores of REVT. The regression analysis showed that word length scores and raw scores of the receptive vocabulary test significantly predict nonword repetition scores.
Conclusion: This study suggests that non-word repetition performance reflect articulation skills and receptive vocabulary. The results support the clinical usefulness of nonword repetition task for screening children who may be at risk for speech and language disorders.
