title: Effects of video modelling on emerging speech in an adult with traumatic brain injury: preliminary findings.
abstract: 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.
  
  
  METHODS
  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
  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.
  
  
  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.
