Abstract

Procedural discourse is a monologue discourse task concerned with explaining to a listener how a particular activity is carried out. The study reported here is part of a series of investigations into discourse abilities following severe traumatic brain injury (TBI). The aim of this study was to compare the procedural discourse skills of a group of 26 TBI speakers, with those of two demographically distinct control groups. The first control group comprised 26 non-TBI orthopaedic patients, and the second control group comprised 26 university students. These control groups were selected because of the hypothesis that premorbid demographic factors could influence sociolinguistic skills, and hence performance on a procedural discourse task. The TBI group was systematically compared with the control groups on content, productivity, and pragmatic measures. They were not significantly different from orthopaedic patients on measures relating to content and productivity; however, they did differ significantly from the university students on these measures. The TBI group differed significantly from both control groups with respect to the production of pragmatic errors, and these were predominantly concerned with information transfer. The results are discussed in relation to issues in selecting control groups for discourse research following TBI, together with the clinical implications of the findings.
