One of the main questions in the research of specific language impairment (SLI) is whether
the language characteristics of children with SLI are similar to those of younger typically
developing (TD) children (quantitative difference), or do they differ entirely and are never
observed in typical development (qualitative difference). The aim of this study was to
investigate this question in the phonological domain, by comparing the repetitions of SLI
children with those of younger TD children, obtained with a nonword repetition task (NRT)
in Serbian. The study included 75 TD children aged 3 to 7 (15 per one-year age group) and
50 children with SLI aged 4 to 8 (8-11 per one-year age group). The used NRT consisted of
48 nonwords with varying prosodic complexity, constructed according to the characteristics
of the Serbian language. The prerecorded nonwords were presented to the children in two
randomized orders, and their task was to repeat each nonword after hearing it. The repet...itions
were recorded, transcribed, and coded for accuracy and 16 types of errors on the word,
syllable and phoneme level. Four one-way MANOVAs were performed for SLI children of
different ages and younger TD children (SLI 5 – TD 3, SLI 6 – TD 3, SLI 7 – TD 4, SLI 8 –
TD 5), from whom they did not differ significantly on the overall accuracy on the task
(number of incorrect repetitions). These analyses, performed on the number of repetitions
containing each of the 16 errors, showed no significant main effect of group for any of the
compared ages. There were, however, significant group differences for some errors at
different ages (F(1,24)>4.45, p<.05, for 8 errors), e.g., SLI children age 7 had significantly
more syllable omissions and consonant metatheses than TD children age 4; SLI age 8 had
significantly more coda consonant additions than TD age 5. We may conclude that Serbian
children with SLI generally make the same types and number of errors in repetitions as
younger TD children, indicating a developmental delay, and a quantitative difference in
language characteristics between the two groups. The observed differences in the number of
some specific errors, however, may indicate an asynchronous delay in the acquisition of some
phonological parameters in SLI. This may lead to slightly atypical patterns, and qualitative
differences in language characteristics of SLI and TD children. Further analyses of the error
patterns occurring in nonword repetitions are required to confirm this.
