The purposes of this study were (1) to compare the non-word repetition performance according to syllable length, (2) to compare the sentence repetition performance according to syntactic complexity in children with late talker and normal children, (3) to investigate the correlation of non-word repetition, sentence repetition and various other factors such as chronological age, vocabulary test score, and percentage of correct consonant for each group.
A total of 40 children composed of 20 with late talker aged from 2 to 3 years old and 20 normal children participated in this study. Children were tested on Korean Denver Ⅱ(Sin et al., 2001), REVT(Receptive-Expressive Vocabulary Test, REVT, Kim et al., 2009), U-TAP(Urimal Test of Articulation and Phonology, Kim & Sin, 2004), non-word repetition(Lee et al, 2013), sentence repetition(An & Kim, 2000).
The results were revealed as follows:
First of all, a 2-way mixed ANOVA result at each syllable length showed that there was no difference in non-word repetition performance between the children with late talker and the normal children group. Each group exhibited the word length effect: As the non-word gets longer, the children's performance becomes worse.
Secondly, in all sentence types in the sentence repetition performance, the performance of the children with late talker was significantly lower than that of the normal children.
Lastly, in correlation analysis, on the data from the normal children, their non-word repetition performance was significantly correlated with chronological age and sentence repetition performance. In contrast to normal children, the non-word repetition performance of the children with late talker was significantly correlated with the percentage of correct consonant and sentence repetition performance.
These results suggest that in the non-word repetition, there is no significant difference in the performance of the children with late talker and that of the normal children. On the other hand, in the sentence repetition performance, the normal children scored higher than the children with late talker, which shows that the children with late talker may suffer deficient ability in phrase development and sentence processing. Therefore, this research supports the notion that the sentence repetition performance is a more reliable test tool than the non-word repetition as it accurately screens the children with late talker.
