Abstract

This study investigated inference comprehension performance in adolescents who had suffered a traumatic brain injury (TBI). Using stimuli adapted from Lehman-Blake and Tompkins, participants listened to short paragraphs that varied according to the working memory demands of the task and answered comprehension questions that required inferences to be generated. Six adolescents, aged 12–16 years, who had suffered a TBI prior to the age of 10 years, were assessed and their performance was compared to six individually age-matched peers with typical development. Analysis revealed that individuals with TBI did not differ from non-injured peers in their understanding of inferences when the storage demands of the task were minimized. However, when storage demands were high, adolescents with TBI performed poorly compared to their age-matched peers. Results are discussed relative to a working-memory hypothesis of impairment following TBI.
