There is a debate about whether the language of children with primary language
disorders and normal cognitive levels is qualitatively different from those with
language impairments who have low or borderline non-verbal IQ (NVIQ). As
children reach adolescence, this distinction may be even harder to ascertain,
especially in naturalistic settings. Narrative may provide a useful,
ecologically valid way in which to assess the language ability of adolescents
with specific language impairment (SLI) who have intact or lowered NVIQ and to
determine whether there is any discernable difference in every day language.
Nineteen adolescents with a history of SLI completed two narrative tasks: a
story telling condition and a conversational condition. Just under half the
group (n = 8) had non-verbal IQs of 85. The remaining 11 had NVIQs in
the normal range or above. Four areas of narrative (productivity, syntax,
cohesion and performance) were assessed. There were no differences between the
groups on standardized tests of language. However, the group with low NVIQ were
poorer on most aspects of narrative, suggesting that cognitive level is
important, even when language is the primary disorder. The groups showed similar
patterns of differences between story telling and conversational narrative. It
was concluded that adolescents with a history of SLI and poor cognitive levels
have poorer narrative skills than those with normal range NVIQ even though these
may not be detected by standardized assessment. Their difficulties present as
qualitatively similar to those with normal range NVIQ and narratives appear
impoverished rather than inaccurate.
