Language and memory profiles of adolescents with traumatic brain injury

The performance of adolescents who suffered a traumatic brain injury in childhood, on language comprehension tasks with varying working memory demands, was examined. It was hypothesized that adolescents with a traumatic brain injury would perform more poorly than their non-injured peers, particularly on those tasks with high working memory demands. A case study design allowed for both group and intra-participant comparisons. A battery of language comprehension and working memory tasks was administered to six adolescents aged 12-16 years. Their performance was compared with six individually age-matched peers with typical development and to the normative data of the standardized tests. Intra-participant performance was examined by comparing results across language tasks that varied in working memory demands. Analysis revealed that individuals with traumatic brain injury performed poorly compared with their age-matched peers. However, the pattern of listening comprehension impairment differed across individuals and marked variability within the comprehension profiles for some individuals with traumatic brain injury was evident. Language comprehension tasks with high working memory demands generally posed the most difficulty for individuals with traumatic brain injury.
