Abstract Primary objective: Research has shown that traumatic brain injury (TBI)
can affect a person's ability to perform previously learned skills. Dysexecutive
syndrome and inattention, for example, alongside a number of other cognitive and
behavioural impairments such as memory loss and lack of motivation, significantly
affect day-to-day functioning following TBI. This study examined the efficacy of
video modelling in emerging speech in an adult male with TBI caused by an
assault. Research design: In an effort to identify functional relations between
this novice intervention and the target behaviour, experimental control was
achieved by using within-system research methodology, overcoming difficulties of
forming groups for such an highly non-homogeneous population. Methods and
procedures: Across a number of conditions, the participant watched a videotape in
which another adult modelled a selection of 19 spoken words. When this modelled
behaviour was performed in vivo, then generalization across 76 other words in the
absence of a videotape took place. Main outcomes and results: It was revealed
that video modelling can promote the performance of previously learned behaviours
related to speech, but more significantly it can facilitate the generalization of
this verbal behaviour across untrained words. Conclusions: Video modelling could
well be added within the rehabilitation programmes for this population.
