ABSTRACT |
This study attempted to ex amine and compare receptive and expressive vocabulary abilities of children with speech and/ or language disorder s to normally developing children using the Korean Ver sion of Peabody Picture Vocabulary T est - Revised (PPVT -R) and the Korean Ver sion of Boston Naming T est (K- BNT ). The ages of the subject group of this study ranged from two to six year s. T hey were divided into 3 groups which included the normal group (100 cases ), the language disorder group (54 cases ), and the speech disorder group (30 cases ). T he speech and language disorder groups contained 2 subgroups , respectively : LD and MR for the language group, and articulation and stuttering for the speech group. The collected data were analyzed by a quantitative statistical method using SPSS 8.0. T he result s revealed the following : (1) receptive and expres sive vocabulary increased very rapidly in normally developing children in all ages while expres sive vocabulary spurt was observed at two- to- three- as well as three- tofour - year - olds ; (2) LD children s receptive and expressive vocabulary scores did not show any meaningful differences between adjacent age groups , which means slow growth . Compared to the normal and the speech groups their scores were about half except for expressive vocabulary ; (3)the speech disorder group showed a few differences in receptive vocabulary compared to the normal group. No statistical difference between three and four - year - olds was observed, whereas expres sive vocabulary lag was noted among the four - year s - old children and above; and, (4) the correlation between receptive and expres sive vocabulary was high (.78- .90) for the normal, LD, articulation , and stut - tering children. But , it was but relatively low among MR children . T his study may contribute in explaining the vocabulary development of normal and speech - language impaired children . It was also found that single-word vocabulary test s could be used as effective screening test s for speech - language disorder s. Furthermore, error analysis of vocabulary test result s is expected for efficient therapy and intervention. |
